COUNT, DUAL COUNTER, RATE AND SLAVE DISPLAY 0.56" RED SUNLIGHT READABLE DISPLAY VARIABLE INTENSITY DISPLAY 10 POINT SCALING FOR NON-LINEAR PROCESSES (PAXI) FOUR SETPOINT ALARM OUTPUTS (W/Option Card) RETRANSMITTED ANALOG OUTPUT (W/Option Card) (PAXI) COMMUNICATION AND BUS CAPABILITIES (W/Option Card) (PAXI) BUS CAPABILITIES; DEVICENET, MODBUS, AND PROFIBUS-DP CRIMSON® PROGRAMMING SOFTWARE (PAXI) ETHERNET(W/ External Gateway) (PAXI) NEMA 4X/IP65 SEALED FRONT BEZEL GENERAL DESCRIPTION The PAX Digital Input Panel Meters offer many features and performance capabilities to suit a wide range of industrial applications. Available in three different models, PAXC Counter/Dual Counter, PAXR Rate Meter and the PAXI which offers both counting and rate in the same package. Refer to pages 4 - 5 for the details on the specific models. The PAXC and PAXR offer only the Setpoint Option, while the PAXI is the fully featured version offering all the capabilities as outlined in this bulletin as well as a slave display feature. The option cards allow the opportunity to configure the meter for present applications, while providing easy upgrades for future needs. The meters employ a bright 0.56" LED display. The meters are available with a red sunlight readable or standard green LED display. The intensity of the display can be adjusted from dark room applications up to sunlight readable, making it ideal for viewing in bright light applications. The meters accept digital inputs from a variety of sources including switch contacts, outputs from CMOS or TTL circuits, magnetic pickups and all standard RLC sensors. The meter can accept directional, uni-directional or Quadrature signals simultaneously. The maximum input signal varies up to 34 KHz depending on the count mode and function configurations programmed. Each input signal can be independently scaled to various process values. The Rate Meters provide a MAX and MIN reading memory with programmable capture time. The capture time is used to prevent detection of false max or min readings which may occur during start-up or unusual process events. Optional digital output cards provide the meter with up to four setpoint outputs. The cards are available as dual relay, quad relay, quad sinking transistor, quad sourcing transistor/SSR drive, or dual triac/dual SSR drive outputs. The setpoint alarms can be configured to suit a variety of control and alarm requirements. Communication and Bus Capabilities are also available as option cards for the PAXI only. These include RS232, RS485, Modbus, DeviceNet, and Profibus-DP. Readout values and setpoint alarm values can be controlled through the bus. Additionally, the meters have a feature that allows a remote computer to directly control the outputs of the meter. With an RS232 or RS485 card installed, it is possible to configure the meter using Red Lion’s Crimson software. The configuration data can be saved to a file for later recall. A linear DC output signal is available as an option card for the PAXI only. The card provides either 20 mA or 10 V signals. The output can be scaled independent of the input range and can track any of the counter or rate displays. Once the meters have been initially configured, the parameter list may be locked out from further modification in its entirety or only the setpoint values can be made accessible. The meters have been specifically designed for harsh industrial environments. With NEMA 4X/IP65 sealed bezel and extensive testing of noise effects to CE requirements, the meter provides a tough yet reliable application solution. SAFETY SUMMARY All safety related regulations, local codes and instructions that appear in this literature or on equipment must be observed to ensure personal safety and to prevent damage to either the instrument or equipment connected to it. If equipment is used in a manner not specified by the manufacturer, the protection provided by the equipment may be impaired. Do not use this meter to directly command motors, valves, or other actuators not equipped with safeguards. To do so can be potentially harmful to persons or equipment in the event of a fault to the meter.

1.0 insTalling The meTer Installation The PAX meets NEMA 4X/IP65 requirements when properly installed. The unit is intended to be mounted into an enclosed panel. Prepare the panel cutout to the dimensions shown. Remove the panel latch from the unit. Slide the panel gasket over the rear of the unit to the back of the bezel. The unit should be installed fully assembled. Insert the unit into the panel cutout. While holding the unit in place, push the panel latch over the rear of the unit so that the tabs of the panel latch engage in the slots on the case. The panel latch should be engaged in the farthest forward slot possible. To achieve a proper seal, tighten the latch screws evenly until the unit is snug in the panel (Torque to approximately 7 in-lbs [79N-cm]). Do not over-tighten the screws. Installation Environment The unit should be installed in a location that does not exceed the operating temperature and provides good air circulation. Placing the unit near devices that generate excessive heat should be avoided. The bezel should only be cleaned with a soft cloth and neutral soap product. Do NOT use solvents. Continuous exposure to direct sunlight may accelerate the aging process of the bezel. Do not use tools of any kind (screwdrivers, pens, pencils, etc.) to operate the keypad of the unit.

The option cards are separately purchased optional cards that perform specific functions. These cards plug into the main circuit board of the meter. The option cards have many unique functions when used with the PAX. Note: The PAXC and PAXR only use the setpoint option card. CAUTION: The option card and main circuit board contain static sensitive components. Before handling the cards, discharge static charges from your body by touching a grounded bare metal object. Ideally, handle the cards at a static controlled clean workstation. Also, only handle the cards by the edges. Dirt, oil or other contaminants that may contact the cards can adversely affect circuit operation. To Install: 1. With the case open, locate the option card connector for the card type to be installed. The types are keyed by position with different main circuit board connector locations. When installing the card, hold the meter by the rear terminals and not by the front display board.* 2. Install the option card by aligning the card terminals with the slot bay in the rear cover. Be sure the connector is fully engaged and the tab on the option card rests in the alignment slot on the display board. 3. Slide the meter base back into the case. Be sure the rear cover latches fully into the case. 4. Apply the option card label to the bottom side of the meter in the designated area. Do Not Cover the vents on the top surface of the meter. The surface of the case must be clean for the label to adhere properly. 3.0 insTalling OpTiOn Cards Internal Supply (18 V unregulated) External Supply (30 V ) max Quad Sourcing Open Collector Output Card Supply Select * If installing the Quad sourcing Option Card (PAXCDS40), set the jumper for internal or external supply operation before continuing.

2.1 SETTING THE JUMPER
The meter has one jumper for user input logic. When using the user inputs this jumper must be set before applying power. The Main Circuit Board figure shows the location of the jumper and DIP switch. The user input jumper determines signal logic for the user inputs, when they are used with user functions or for input signal direction. All user inputs are set by this jumper.
2.2 SETTING THE INPUT DIP SWITCHES
The meter has six DIP switches for Input A and Input B terminal set-up that must be set before applying power. NOTE: The PAXR only uses switches 1-3. SWITCHES 1 and 4 LOGIC: Input trigger levels VIL = 1.5 V max.; VIH = 3.75 V min. MAG: 200 mV peak input (must also have SRC on). Not recommended with counting applications. SWITCHES 2 and 5 SRC.: Adds internal 3.9 K Ω pull-down resistor, 7.3 mA max. @ 28 VDC, VMAX = 30 VDC. SNK.: Adds internal 7.8 KΩ pull-up resistor to +12 VDC, I MAX = 1.9 mA. SWITCHES 3 and 6 HI Frequency: Removes damping capacitor and allows max. frequency. LO Frequency : Adds a damping capacitor for switch contact bounce. Also limits input frequency to 50 Hz and input pulse widths to 10 msec. Main Circuit Board REAR TERMINALS FRONT DISPLAY INPUT SET-UP DIP SWITCHES USER INPUT JUMPER 1 2 3 4 5 6 SRC SNK Finger Tab Finger Tab To access the jumper and switches, remove the meter base from the meter case by firmly squeezing and pulling back on the side rear finger tabs. This should lower the latch below the case slot (which is located just in front of the finger tabs). It is recommended to release the latch on one side, then start the other side latch. Warning: Exposed line voltage exists on the circuit boards. Remove all power to the meter and load circuits before accessing inside of the meter. 1ON Input B SRC. Input B LO Freq. Input B MAG.

Electrical connections are made via screw-clamp terminals located on the back of the meter. All conductors should conform to the meter’s voltage and current ratings. All cabling should conform to appropriate standards of good installation, local codes and regulations. It is recommended that the power supplied to the meter (DC or AC) be protected by a fuse or circuit breaker. When wiring the meter, compare the numbers embossed on the back of the meter case against those shown in wiring drawings for proper wire position. Strip the wire, leaving approximately 0.3" (7.5 mm) bare lead exposed (stranded wires should be tinned with solder.) Insert the lead under the correct screw- clamp terminal and tighten until the wire is secure. (Pull wire to verify tightness.) Each terminal can accept up to one #14 AWG (2.55 mm) wire, two #18 AWG (1.02 mm), or four #20 AWG (0.61 mm). EMC INSTALLATION GUIDELINES Although Red Lion Controls Products are designed with a high degree of immunity to Electromagnetic Interference (EMI), proper installation and wiring methods must be followed to ensure compatibility in each application. The type of the electrical noise, source or coupling method into a unit may be different for various installations. Cable length, routing, and shield termination are very important and can mean the difference between a successful or troublesome installation. Listed are some EMI guidelines for a successful installation in an industrial environment. 1. A unit should be mounted in a metal enclosure, which is properly connected to protective earth. 2. Use shielded cables for all Signal and Control inputs. The shield connection should be made as short as possible. The connection point for the shield depends somewhat upon the application. Listed below are the recommended methods of connecting the shield, in order of their effectiveness. a. Connect the shield to earth ground (protective earth) at one end where the unit is mounted. b. Connect the shield to earth ground at both ends of the cable, usually when the noise source frequency is over 1 MHz. 3. Never run Signal or Control cables in the same conduit or raceway with AC power lines, conductors, feeding motors, solenoids, SCR controls, and heaters, etc. The cables should be run through metal conduit that is properly grounded. This is especially useful in applications where cable runs are long and portable two-way radios are used in close proximity or if the installation is near a commercial radio transmitter. Also, Signal or Control cables within an enclosure should be routed as far away as possible from contactors, control relays, transformers, and other noisy components. 4. Long cable runs are more susceptible to EMI pickup than short cable runs. 5. In extremely high EMI environments, the use of external EMI suppression devices such as Ferrite Suppression Cores for signal and control cables is effective. The following EMI suppression devices (or equivalent) are recommended: Fair-Rite part number 0443167251 (RLC part number FCOR0000) Line Filters for input power cables: Schaffner # FN2010-1/07 (Red Lion Controls # LFIL0000) 6. To protect relay contacts that control inductive loads and to minimize radiated and conducted noise (EMI), some type of contact protection network is normally installed across the load, the contacts or both. The most effective location is across the load. a. Using a snubber, which is a resistor-capacitor (RC) network or metal oxide varistor (MOV) across an AC inductive load is very effective at reducing EMI and increasing relay contact life. b. If a DC inductive load (such as a DC relay coil) is controlled by a transistor switch, care must be taken not to exceed the breakdown voltage of the transistor when the load is switched. One of the most effective ways is to place a diode across the inductive load. Most RLC products with solid state outputs have internal zener diode protection. However external diode protection at the load is always a good design practice to limit EMI. Although the use of a snubber or varistor could be used. RLC part numbers: Snubber: SNUB0000 Varistor: ILS11500 or ILS23000 7. Care should be taken when connecting input and output devices to the instrument. When a separate input and output common is provided, they should not be mixed. Therefore a sensor common should NOT be connected to an output common. This would cause EMI on the sensitive input common, which could affect the instrument’s operation.

Before connecting the wires, the User Input Logic Jumper should be verified for proper position. If User Input 1 and/ or 2 are wired for quadrature or directional counting, an additional switching device should not be connected to that User Input terminal. Only the appropriate User Input terminal has to be wired.

CAUTION: Sensor input common is NOT isolated from user input common. In order to preserve the safety of the meter application, the sensor input common must be suitably isolated from hazardous live earth referenced voltage; or input common must be at protective earth ground potential. If not, hazardous voltage may be present at the User Inputs and User Input Common terminals. Appropriate considerations must then be given to the potential of the user input common with respect to earth ground; and the common of the isolated option cards with respect to input common.

Factory setting for the F1, and F2 keys is NO mode. * Factory setting for the RST key is (Reset Display). PROGRAMMING MODE ENTRY (PAR KEY) The meter normally operates in the Display Mode. No parameters can be programmed in this mode. The Programming Mode is entered by pressing the PAR key. If it is not accessible then it is locked by either a security code, or a hardware lock. Two types of programming modes are available. Quick Programming Mode permits only certain parameters to be viewed and/or modified. All meter functions continue to operate except the front panel keys change to Programming Mode Operations. Quick Programming Mode is configured in Module 3. Full Programming Mode permits all parameters to be viewed and modified. In this mode, incoming counts may not be recognized correctly, the front panel keys change to Programming Mode Operations and certain user input functions are disabled. Throughout this document, Programming Mode (without Quick in front) always refers to “Full” Programming. MODULE ENTRY (ARROW & PAR KEYS) The Programming Menu is organized into nine modules. These modules group together parameters that are related in function. The display will alternate between and the present module. The arrow keys ( F1 and F2) are used to select the desired module. The displayed module is entered by pressing the PAR key. MODULE MENU (PAR KEY) Each module has a separate module menu (which is shown at the start of each module discussion). The PAR key is pressed to advance to a particular parameter to be changed, without changing the programming of preceding parameters. After completing a module, the display will return to . Programming may continue by accessing additional modules. SELECTION / VALUE ENTRY (ARROW & PAR KEYS) For each parameter, the display alternates between the present parameter and the selections/value for that parameter. The arrow keys (F1 and F2) are used to move through the selections/values for that parameter. Pressing the PAR key, stores and activates the displayed selection/value. This also advances the meter to the next parameter. For numeric values, the RST key may be used to select a specific digit to be changed. Once a digit is selected, the arrow keys are used to increment or decrement that digit to the desired number. PROGRAMMING MODE EXIT (DSP KEY or at PAR KEY) The Programming Mode is exited by pressing the DSP key (from anywhere in the Programming Mode) or the PAR key (with displayed). This will commit any stored parameter changes to memory and return the meter to the Display Mode. If a parameter was just changed, the PAR key should be pressed to store the change before pressing the DSP key. (If power loss occurs before returning to the Display Mode, verify recent parameter changes.) PROGRAMMING TIPS It is recommended to start with Module 1 for counting and Module 4 for rate. If lost or confused while programming, press the DSP key and start over. When programming is complete, it is recommended to record the parameter programming on the Parameter User Chart and lock out parameter programming with a user input or lock-out code. FACTORY SETTINGS Factory Settings may be completely restored in Module 9. This is a good starting point for programming problems. Most parameters can be left at their Factory Settings without affecting basic start-up. ALTERNATING SELECTION DISPLAY In the explanation of the modules, the following dual display with arrows will appear. This is used to illustrate the display alternating between the parameter on top and the parameter’s Factory Setting on the bottom.

COUNTER A RESET ACTION When Counter A is reset, it returns to zero or Counter A count load value. This reset action affects all Counter A resets, except the Setpoint Counter Auto Reset in Module 6. COUNTER A DECIMAL POSITION This selects the decimal point position for Counter A and any setpoint value assigned to Counter A. The selection will also affect Counter A scale factor calculations. COUNTER A SCALE FACTOR The number of input counts is multiplied by the scale factor and the scale multiplier to obtain the desired process value. A scale factor of 1.00000 will result in the display of the actual number of input counts. (Details on scaling calculations are explained at the end of this section.) COUNTER A SCALE MULTIPLIER The number of input counts is multiplied by the scale multiplier and the scale factor to obtain the desired process value. A scale multiplier of 1 will result in only the scale factor affecting the display. (Details on scaling calculations are explained at the end of this section.) COUNTER A COUNT LOAD VALUE When reset to count load action is selected, Counter A will reset to this value. COUNTER A RESET POWER-UP Counter A may be programmed to reset at each meter power-up. This enables the prescaler output. The prescaler output is useful for providing a lower frequency scaled pulse train to a PLC or another external counter. On each falling edge of Input A, the prescaler output register increments by the prescaler scale value ( ). When the register equals or exceeds 1.0000, a pulse is output and the register is lowered by 1.0000. The prescaler register is reset to zero whenever Counter A is reset (except for Setpoint Counter Auto Reset). (See Prescaler Output Figure.) Module 1 is the programming for Counter A, Counter B and the Prescaler Output. Counter B parameters follow the Prescaler parameters. For maximum input frequency, the counters should be set to mode NONE and the Prescaler to NO when they are not in use. When set to NONE or NO, the remaining related parameters are not accessible. A corresponding annunciator indicates the counter being shown in the Display Mode. An Exchange Parameter Lists feature for scale factors and count load values is explained in Module 2.

COUNTER B OPERATING MODE Select the operating mode for Counter B. SELECTION MODE DESCRIPTION Does not count. Count X1 Adds Input B falling edge. w/direction Adds Input B falling edge if User 2 is high. Subtracts Input B falling edge if User 2 is low. Quad X1 Adds Input B rising edge when User 2 is high. Subtracts Input B falling edge when User 2 is high. Quad X2 Adds Input B rising edge when User 2 is high and Input B falling edge when User 2 is low. Subtracts Input B falling edge when User 2 is high and Input B rising edge when User 2 is low. Count X2 Adds Input B rising and falling edges. w/direction Adds Input B rising and falling edges if User 2 is high. Subtracts Input B rising and falling edge if User 2 is low. COUNTER B RESET ACTION When Counter B is reset, it returns to zero or Counter B count load value. This reset action affects all Counter B resets, except the Setpoint Counter Auto Reset Action in Module 6. COUNTER B DECIMAL POSITION This selects the decimal point position for Counter B and any setpoint value assigned to Counter B. The selection will also affect Counter B scale factor calculations. COUNTER B SCALE FACTOR The number of input counts is multiplied by the scale factor and the scale multiplier to obtain the desired process value. A scale factor of 1.00000 will result in the display of the actual number of input counts. (Details on scaling calculations are explained at the end of this section.) COUNTER B SCALE MULTIPLIER The number of input counts is multiplied by the scale multiplier and the scale factor to obtain the desired process value. A scale multiplier of 1 will result in only the scale factor affecting the display. (Details on scaling calculations are explained at the end of this section.) COUNTER B COUNT LOAD VALUE When reset to count load action is selected, Counter B will reset to this value. SCALING CALCULATIONS Each counter has the ability to scale an input signal to a desired display value. This is accomplished by the counter mode (x-), scale factor (x), scale multiplier (x ) and decimal point (x ). The scale factor is calculated using: SF (x) = Desired Display Decimal DDD (Number of pulses per ‘single’ unit x CM x SM) Where: Desired Display Decimal DDD x Counter Decimal Selection 1 0 None 10 0.0 Tenths 100 0.00 Hundredths 1000 0.000 Thousandths 10000 0.0000 Ten Thousandths 100000 0.00000 Hundred Thousandths Number of pulses per ‘single’ unit: pulses per unit generated by the process (i.e. # of pulses per foot) CM: Counter Mode(x-) times factor of the mode 1,2 or 4. SM: Scale Multiplier (x) selection of 1, 0.1 or 0.01. Example: 1. Show feet to the hundredths (0.00) with 100 pulses per foot: Scale Factor would be 100 / (100 x 1 x 1) = 1 (In this case, the scale multiplier and counter mode factor are 1) 2. Show feet with 120 pulses per foot: Scale Factor would be 1 / (120 x 1 x 1) = 0.0083333. (In this case, the scale multiplier of 0.01 could be used: 1 / (120 x 1 x 0.01) = 0.83333 or show to hundredths (0.00): 100 / (120 x 1 x 1) = 0.8333.) General Rules on Scaling 1. It is recommended that, the scale factor be as close as possible to, but not exceeding 1.00000. This can be accomplished by increasing or decreasing the counter decimal point position, using the scale multiplier, or selecting a different count mode. 2. To double the number of pulses per unit, use counter modes direction X2 or quad X2. To increase it by four times, use counter mode quad X4. Using these modes will decrease the maximum input frequency. 3. A scale factor greater than 1.00000 will cause Counter display rounding. In this case, digit jumps could be caused by the internal count register rounding the display. The precision of a counter application cannot be improved by using a scale factor greater than 1. 00000. 4. The number of pulses per single unit must be greater than or equal to the DDD value for the scale factor to be less than or equal to one. 5. Lowering the scale factor can be accomplished by lowering the counter decimal position. (Example: 100 (Hundredths)/10 pulses = 10.000 lowering to 10 (Tenths)/10 = 1.000.) COUNTER B RESET POWER-UP Counter B may be programmed to reset at each meter power-up.
8 DIGIT COUNT VALUES
Any counter display value below -99999 or above 999999 (less decimal point) will consist of a two part display. This display alternates between the least 6 significant digits and the remaining most significant digits beginning with “” in the display. If the display exceeds ± 99999999 the display will roll to zero and continue counting. Outputs cannot be set to counter values above 6 digits. The annunciator, indicating the counter being displayed, will flash when the value is above 6 digits. PAXI: PRESCALER SCALE VALUE The prescaler output frequency is the Input A frequency times the prescaler scale value.

This is the factory setting for all user inputs and function keys except the Reset ( RST) Key. NOTE: When a user input is used to accept a quad or directional input signal, then that user input should be programmed for NO function. RESET DISPLAY When activated (momentary action), the shown display is reset. This is the factory setting for the Reset (RST) Key. EXCHANGE PARAMETER LISTS If a user input is used to select the list then is selected when the user input is not active and and is selected when the user input is active, (maintained action). If a front panel key is used to select the list then the list will toggle for each key press, (momentary action). The meter will suspend ALL operations for approximately 1 msec. while the new values are loaded. The display will only indicate which list is active when the list is changed or when entering any Programming Mode. To program the values for and , first complete the programming of all the parameters. Exit programming and switch to the other list. Re-enter other list values must be reprogrammed. PROGRAMMING MODE LOCK-OUT Programming Mode is locked-out, as long as activated (maintained action). In Module 3, certain parameters can be setup where they are still accessible during Programming Mode Lockout. A security code can be configured to allow complete programming access during user input lockout. Function keys should not be programmed for . The meter issues a block print through the serial port when activated. The data transmitted during the print request is configured in Module 7. If the user input is still active after the transmission is complete (about 100 msec.), an additional transmission will occur. Only one transmission will take place with each function key depression. This selection will only function when a serial communications option card is installed in the meter. Module 2 is the programming for rear terminal user inputs and front panel function keys. Three rear terminal user inputs are individually programmable to perform specific meter control functions. While in the Display Mode, the function is executed when the user input transitions to the active state. (Refer to the user input specifications for active state response times.) Certain user input functions are disabled in “full” Programming Mode. Three front panel function F1, F2 and RST keys are also individually programmable to perform specific meter control functions. While in the Display Mode, the primary function is executed when the key is pressed. Holding the F1 and F2 function keys for three seconds executes a secondary function. It is possible to program a secondary function without a primary function. The front panel key functions are disabled in both Programming Modes. In most cases, if more than one user input and/or function key is programmed for the same function, the maintained (level trigger) actions will be performed while at least one of those user inputs or function keys are activated. The momentary (edge trigger) actions are performed every time any of those user inputs or function keys transition to the active state. All functions are available to both user inputs and function keys. Some of the user functions have a sublist of parameters. The sublist is accessed when PAR is pressed at the listed function. The function will only be performed for the parameters entered as . If a user input or function key is configured for a function with a sublist, then that sublist will need to be scrolled through each time to access the following user inputs or function keys parameters. ADVANCE DISPLAY When activated (momentary action), the display advances to the next display that is not locked out from the Display Mode. Shaded parameters do not apply to the PAXR. The meter issues a block print through the serial port when activated just like the Print Request function. In addition, when activated (momentary action), the meter performs a reset of the displays configured as . The print aspect of this action only functions when a serial communication option card is installed. The reset action functions regardless. DISPLAY DESCRIPTION FACTORY Maximum Minimum

For Input B select . This assignment is independent of the counting modes. The Low Update Time is the minimum amount of time between display updates for the Rate display. Values of 0.1 and 0.2 seconds will update the display correctly but may cause the display to appear unsteady. The factory setting of 1.0 will update the display every second minimum. LOW UPDATE TIME (DISPLAY UPDATE) Module 4 is the programming for the Rate parameters. For maximum input frequency, Rate assignment should be set to when not in use. When set to , the remaining related parameters are not accessible. The Rate value is shown with an annunciator of ‘’ in the Display Mode. Note: For P AXR, is actually on the unit’ s display and is actually on the unit’ s display. The High Update Time is the maximum amount of time before the Rate display is forced to zero. (For more explanation, refer to Input Frequency Calculation.) The High Update Time must be higher than the Low Update Time and higher than the desired slowest readable speed (one divided by pulses per second). The factory setting of 2.0, will force the display to zero for speeds below 0.5 Hz or a pulse every 2 seconds. HIGH UPDATE TIME (DISPLAY ZERO) This selects the decimal point position for Rate, Minimum and Maximum rate displays and any setpoint value assigned to these displays. This parameter does not affect rate scaling calculations. RATE DECIMAL POSITION This parameter specifies the number of linear segments used for the Rate Scaling function. Each linear segment has two scaling points which define the upper and lower endpoints of the segment. The number of segments used depends on the linearity of the process and the display accuracy required as described below. Linear Application – 2 Scaling Points Linear processes use a single segment (two scaling points) to provide a linear Rate display from 0 up to the maximum input frequency. For typical zero based frequency measurements (0 Hz = 0 on display), leave (factory setting). For non-zero based 2 scaling point applications, set , to enter both the Non-linear Application – Up to 10 Scaling Points Non-linear processes may utilize up to nine segments (ten scaling points) to provide a piece-wise linear approximation representing the non-linear function. The Rate display will be linear throughout each individual segment (i.e. between sequential scaling points). Thus, the greater the number of segments, the greater the conformity accuracy. Several linearization equations are available in the software. About Scaling Points Each Scaling Point is specified by two programmable parameters: A desired Rate Display Value ( ) and a corresponding Rate Input Value ( ). Scaling points are entered sequentially in ascending order of Rate Input Value. Two scaling points must be programmed to define the upper and lower endpoints of the first linear segment. Setting , automatically factory sets the first scaling point to 0.0 for typical single segment, zero based applications. When multiple segments are used, the upper scaling point for a given segment becomes the lower scaling point for the next sequential segment. Thus, for each additional segment used, only one additional scaling point must be programmed. The following chart shows the Scaling Points, the corresponding Parameter mnemonics, and the Factory Default Settings for each point. Confirm the Rate Display Value for the first Scaling Point is 0. This parameter is automatically set to 0 and does not appear when . (See Note) Confirm the Rate Input Value for the first Scaling Point is 0.0. (See Note) Note: For all linear and most non-linear applications, the Scaling Point 1 parameters ( and ) should be set to 0 and 0.0 respectively. Consult the factory before using any non-zero values for Scaling Point 1. These parameters are automatically set to 0 and do not appear when . RATE DISPLAY VALUE FOR SCALING POINT 2 Enter the desired Rate Display Value for the second Scaling Point by using the arrow keys. to INPUT DEFAULT 00000.0 INPUT PARAMETER DISPLAY DEFAULT SEGMENT SCALING POINT DISPLAY PARAMETER
RATE INPUT VALUE FOR SCALING POINT 2 Enter the corresponding Rate Input Value for the second Scaling Point by using the arrow keys. Rate Input values for scaling points can be entered by using the Key-in or the Applied method described below. Key-in Method: Enter the Rate Input value ( ) that corresponds to the entered Rate Display value ( ) by pressing the F1 or F2 keys. This value is always in pulses per second (Hz). Applied Method: Apply an external rate signal to the appropriate input terminals. At the Rate Input Value () press and hold the F1 and F2 keys at the same time. The applied input frequency (in Hz) will appear on the display. (To verify correct reading wait for at least the length of the Low Update Time. Then press and hold the F1 and F2 keys at the same time again. The new value should be ± 0.1% of the previous entered value.) Press PAR to enter the displayed frequency as the Rate Input value. To prevent the displayed value from being entered, press DSP. This will take the meter out of Programming Mode and the previous Rate Input value will remain. Rounding values other than one round the Rate display to the nearest increment selected (e.g. rounding of ‘5’ causes 122 to round to 120 and 123 to round to 125). Rounding starts at the least significant digit of the Rate display. RATE DISPLAY ROUND The Low Cut Out value forces the Rate display to zero when the Rate display falls below the value entered. LOW CUT OUT When the Rate value is above the present Maximum rate value for the entered amount of time, the meter will capture that Rate value as the new Maximum value. A delay time helps to avoid false captures of sudden short spikes. Maximum detection will only function if Rate is assigned to Input A or B. The Maximum rate value is shown with an annunciator of ‘ ’ in the display and will continue to function independent of being displayed. MAXIMUM CAPTURE DELAY TIME When the Rate value is below the present Minimum rate value for the entered amount of time, the meter will capture that Rate value as the new Minimum value. A delay time helps to avoid false captures of sudden short spikes. Minimum detection will only function if Rate is assigned to Input A or B. The Minimum rate value is shown with an annunciator of ‘’ in the display and will continue to function independent of being displayed. MINIMUM CAPTURE DELAY TIME RATE SCALING To scale the Rate, enter a Scaling Display value with a corresponding Scaling Input value. (The Display and Input values can be entered by Key-in or Applied Methods.) These values are internally plotted to a Display value of 0 and Input value of 0 Hz. A linear relationship is formed between these points to yield a rate display value that corresponds to the incoming input signal rate. The PAXI and PAXR are capable of showing a rate display value for any linear process. KEY-IN SCALING METHOD CALCULATION If a display value versus input signal (in pulses per second) is known, then those values can be entered into Scaling Display ( x) and Scaling Input (x). No further calculations are needed. If only the number of pulses per ‘single’ unit (i.e. # of pulses per foot) is known, then it can be entered as the Scaling Input value and the Scaling Display value will be entered as the following: NOTES: 1. If # of pulse per unit is less than 10, then multiply both Input and Display values by 10. 2. If # of pulse per unit is less than 1, then multiply both Input and Display values by 100. 3. If the Display value is raised or lowered, then Input value must be raised or lowered by the same proportion (i.e. Display value for per hour is entered by a third less (1200) then Input value is a third less of # of pulses per unit). The same is true if the Input value is raised or lowered, then Display value must be raised or lowered by the same proportion. 4. Both values must be greater than 0.0. EXAMPLE: 1. With 15.1 pulses per foot, show feet per minute in tenths. Scaling Display = 60.0 Scaling Input = 15.1. 2. With 0.25 pulses per gallon, show whole gallons per hour. (To have greater accuracy, multiply both Input and Display values by 10.) Scaling Display = 36000 Scaling Input = 2.5. INPUT FREQUENCY CALCULATION The meter determines the input frequency by summing the number of falling edges received during a sample period of time. The sample period begins on the first falling edge. At this falling edge, the meter starts accumulating time towards Low Update and High Update values. Also, the meter starts accumulating the number of falling edges. When the time reaches the Low Update Time value, the meter looks for one more falling edge to end the sample period. If a falling edge occurs (before the High Update Time value is reached), the Rate display will update to the new value and the next sample period will start on the same edge. If the High Update Time value is reached (without receiving a falling edge after reaching Low Update Time), then the sample period will end but the Rate display will be forced to zero. The High Update Time value must be greater than the Low Update Time value. Both values must be greater than 0.0. The input frequency calculated during the sample period, is then shown as a Rate value determined by either scaling method. RATE DISPLAY EXCEEDED If the rate of the input signal causes a display that exceeds the capacity of the Rate display (5 digits, 99999), then the display will indicate an overflow condition by showing “ ”. During this overflow condition, the Minimum and Maximum rate values will stay at their values even during resets. # of pulses per unit3600Hour # of pulses per unit60Minute # of pulses per unit1Second
COUNTER C SCALE MULTIPLIER The number of input counts is multiplied by the scale multiplier and the scale factor to obtain the desired process value. A scale multiplier of 1 will result in only the scale factor affecting the display. (Details on scaling calculations are explained at the end of Module 1 section.) COUNTER C OPERATING MODE COUNTER C COUNT LOAD VALUE When reset to count load action is selected, Counter C will reset to this value. COUNTER C RESET POWER-UP Counter C may be programmed to reset at each meter power-up. COUNTER C RESET ACTION When Counter C is reset, it returns to zero or Counter C count load value. This reset action affects all Counter C resets, except the Setpoint Counter Auto Reset Action in Module 6. COUNTER C DECIMAL POSITION This selects the decimal point position for Counter C and any setpoint value assigned to Counter C. The selection will also affect Counter C scale factor calculations. COUNTER C SCALE FACTOR The number of input counts is multiplied by the scale factor and the scale multiplier to obtain the desired process value. A scale factor of 1.00000 will result in the display of the actual number of input counts. For the mode of operation, the input signal is scaled directly. For and modes of operation, the math is performed on the input signals and then the result is scaled. To achieve correct results, both Input A and Input B must provide the same amount of pulses per unit of measurement. (Details on scaling calculations are explained at the end of Module 1 section.) Module 5 is the programming for Counter C. For maximum input frequency, the counter operating mode should be set to when not in use. When set to the remaining related parameters are not accessible. The C annunciator indicates that Counter C is being shown in the Display Mode. An Exchange Parameter List feature for scale factor and count load values is explained in Module 2. Select the operating mode for Counter C. Does not count. Counter C counts the incoming pulses from Counter A input as per Counter A mode of operation. The signal is scaled only according to Counter C parameters. Counter C counts the incoming pulses from Counter A and B inputs as per Counter A and B modes of operation. The result is scaled only according to Counter C parameters. (Example: If Counter A is set for Count X1 mode and Counter B is set for Count X2 mode, then Counter C will increment by 1 for each pulse received on Input A and increment by 2 for each pulse received on Input B. Counter C scale settings are then applied and the result is displayed.) Counter C counts the incoming pulses from Counter A and B inputs as per Counter A and B modes of operation and subtracts the B counts from the A counts. The result is scaled only according to Counter C parameters. (Example: If Counter A is set for Count X1 mode and Counter B is set for Count X2 mode, then Counter C will increment by 1 for each pulse received on Input A and decrement by 2 for each pulse received on Input B. Counter C scale settings are then applied and the result is displayed.) Note: When using Add Ab or Sub Ab, Counter A, B and C must all be reset at the same time for the math to be performed on the display values.

To have setpoint outputs, a setpoint option card needs to be installed into the PAX (see Ordering Information). Depending on the card installed, there will be two or four setpoint outputs available. For setpoint hardware and wiring details, refer to the bulletin shipped with the option card. For maximum input frequency, unused Setpoints should be configured for action. The setpoint assignment and the setpoint action determine certain setpoint feature availability. The chart below illustrates this. SETPOINT PARAMETER AVAILABILITY SETPOINT SELECT Select a setpoint (alarm output) to open the remaining module menu. (The “” in the following parameters will reflect the chosen setpoint number.) After the chosen setpoint is programmed, the display will default to . Select the next setpoint to be programmed and continue the sequence for each setpoint. Pressing PAR at will exit Module 6. SETPOINT ANNUNCIATORS disables the display of the setpoint annunciator. Normal ( ) displays the corresponding setpoint annunciator of an “on” alarm output. Reverse ( ) displays the corresponding setpoint annunciator of an “off” alarm output. flashes the display and the corresponding setpoint annunciator of an “on” alarm output. SETPOINT OUTPUT LOGIC Normal ( ) turns the output “on” when activated and “off” when deactivated. Reverse () turns the output “off” when activated and “on” when deactivated. SETPOINT POWER UP STATE will restore the output to the same state it was at before the meter was powered down. will activate the output at power up. will deactivate the output at power up.

PAXC & I: COUNTER AUTO RESET PAXI & R: SETPOINT ON DELAY PAXI & R: SETPOINT OFF DELAY PAXI & R: SETPOINT HYSTERESIS PAXC & I: SETPOINT ASSIGNMENT SETPOINT ACTION : When not using a setpoint, it should be set to (no action). For Counter Assignments: With Timed Out action, the setpoint output activates when the count value equals the setpoint value and deactivates after the Time Out value. This action is not associated with Boundary types. With boundary action, the setpoint output activates when the count value is greater than or equal to (for = ) or less than or equal to (for = ) the setpoint value. The setpoint output will deactivate when the count value is less than (for = ) or greater than (for = ) the setpoint value. With Latch action, the setpoint output activates when the count value equals the setpoint value. The output remains active until reset. This action is not associated with Boundary types. For Rate Assignments: With Timed Out action, the setpoint output cycles when the rate value is greater than or equal to (for = ) or less than or equal to (for = ) the setpoint value. The Setpoint Time Out () and Setpoint On Delay ( ) values determine the cycling times. With Boundary action, the setpoint output activates when the rate value is greater than or equal to (for = ) or less than or equal to (for = ) the setpoint value. The setpoint output will deactivate (Auto reset) as determined by the hysteresis value. With Latch action, the setpoint output activates when the rate value is equal to the setpoint value. The setpoint output remains active until reset. If after reset, the rate value is greater than or equal to (for = ) or less than or equal to (for = ) the setpoint value, the output will reactivate. Select the display that the setpoint is to be assigned. SETPOINT VALUE Enter the desired setpoint value. Setpoint values can also be entered in the Quick Programming Mode when the setpoint is configured as in Module 3. (See Module 2 for Exchange Parameter Lists explanation.) SETPOINT TRACKING If a selection other than NO is chosen, then the value of the setpoint being programmed (“n”) will track the entered selection’s value. Tracking means that when the selection’s value is changed, the “n” setpoint value will also change (or follow) by the same amount. SETPOINT BOUNDARY TYPE activates the output when the assigned display value ( ) equals or exceeds the setpoint value. activates the setpoint when the assigned display value is less than or equal to the setpoint. SETPOINT STANDBY OPERATION Selecting will disable low acting setpoints at a power up until the display value crosses into the alarm “off” area. Once in the alarm “off” area, the setpoint will function according to the configured setpoint parameters. The hysteresis value is added to (for = ), or subtracted from (for = ), the setpoint value to determine at what value to deactivate the associated setpoint output. Hysteresis is only available for setpoints assigned to the Rate with boundary action. This is the amount of time the Rate display must meet the setpoint deactivation requirements (below hysteresis for high acting and above hysteresis for low acting) before the setpoint’s output deactivates. This is the amount of time the Rate display must meet the setpoint activation requirements (below setpoint for = and above setpoint for = ) before the setpoint’s output activates. If the Rate Setpoint Action is Timed Out, this is the amount of time the output is off during the on / off output cycling. SETPOINT TIME OUT If the setpoint action is Timed Out and the setpoint is assigned to Rate, then this is the amount of time the output is on during the on / off output cycling. If the setpoint action is Timed Out and the setpoint is assigned to Count, then this is the amount of time the output will activate once the count value equals the setpoint value. This automatically resets the display value of the Setpoint Assignment () counter each time the setpoint value is reached. This reset may be different than the Counter’s Reset Action (x) in Module 1 or 5. SELECTION ACTION No auto reset. Reset to zero at the start of output activation. Reset to count load value at the start of output activation. Reset to zero at the end of output activation. ( action only). Reset to count load value at the end of output activation. ( action only).
PAXC & I: SETPOINT RESET WHEN SPn+1 DEACTIVATES PAXC & I: SETPOINT RESET WHEN SPn+1 ACTIVATES Select , so the setpoint output will deactivate (reset) when SPn +1 activates. (Example: SP1 deactivates when SP2 activates and SP4 when SP1 activates.) The last setpoint will wrap around to the first. Select , so the setpoint output will deactivate (reset) when SPn +1 activates and then times out (deactivates). This function may only be used if the SPn+1 is programmed for Setpoint Action of . (Example SP1 deactivates when SP2 is activated and then times out.) The last setpoint will wrap around to the first. (For Reverse Action, The Alarm state is opposite.) LOW ACTING WITH NO DELAY LOW ACTING WITH DELAY HIGH ACTING WITH TIMEOUT LOW ACTING WITH TIMEOUT HIGH ACTING WITH NO DELAY HIGH ACTING WITH DELAY PAXC & I: SETPOINT RESET WITH DISPLAY RESET Select , so the setpoint output will deactivate (reset) when the Setpoint Assignment ( ) counter display resets. The only exception is if the assigned counter is reset by a Counter Auto reset generated by another setpoint. PAXR & I: SETPOINT (ALARM) FIGURES FOR RATE

Normally, the baud rate is set to the highest value that all the serial equipment is capable of transmitting and receiving. BAUD RATE ABBREVIATED PRINTING Select for full print or Command T transmissions (meter address, parameter data and mnemonics) or for abbreviated print transmissions (parameter data only). This will affect all the parameters selected in the print options. (If the meter address is 0, it will not be sent during a full transmission.) - Enters the sub-menu to select the meter parameters to appear during a print request. For each parameter in the sub-menu, select for that parameter information to be sent during a print request or for that parameter information not to be sent. A print request is sometimes referred to as a block print because more than one parameter information (meter address, parameter data and mnemonics) can be sent to a printer or computer as a block.

DATA BIT Select either 7 or 8 bit data word lengths. Set the word length to match the other serial communications equipment on the serial link. PARITY BIT Set the parity bit to match that of the other serial communications equipment on the serial link. The meter ignores the parity when receiving data and sets the parity bit for outgoing data. If no parity is selected with 7 bit word length, an additional stop bit is used to force the frame size to 10 bits. METER ADDRESS Enter the serial meter (node) address. The address range is dependent on the parameter. With a single unit, configured for RLC protocol ( = ), an address is not needed and a value of zero can be used.

These parameters are used to match the serial settings of the PAXI with those of the host computer or other serial device, such as a terminal or printer. This programming module can only be accessed if an RS232 or RS485 Serial Communications card is installed. This section also includes an explanation of the commands and formatting required for communicating with the PAXI. In order to establish serial communications, the user must have host software that can send and receive ASCII characters or Modbus protocol. Red Lion’s Crimson software can be used for configuring the PAXI (See Ordering Information). For serial hardware and wiring details, refer to the bulletin shipped with the option card. This section does NOT apply to the DeviceNet or Profibus-DP communication cards. For details on the operation of the Fieldbus cards, refer to the bulletin shipped with each card. u - Modbus RTU - RLC Protocol (ASCII) Select the desired communications protocol. Modbus protocol provides access to all meter values and parameters. Since Modbus is included within the PAXI, the PAX Modbus option card, PAXCDC4, should not be used. The PAXCDC1 (RS485), or PAXCDC2 (RS232) card should be used instead. COMMUNICATIONS TYPE u TRANSMIT DELAY Following a transmit value (‘*’ terminator) or Modbus command, the PAXI will wait this minimum amount of time before issuing a serial response. Parameters below only appear when Communications Type parameter
SERIAL MODBUS COMMUNICATIONS Modbus Communications requires that the Serial Communications Type Parameter (tYPE) be set to Modbus RTU (Mbrtu) or Modbus ASCII (MbASC). PAXI CONFIGURATION USING CRIMSON AND SERIAL COMMUNICATIONS CARD 1. Install Crimson software. 2. Install RS232 or RS485 card and connect communications cable from PAXI to PC. 3. Supply power to PAXI. 4. Configure serial parameters to Modbus RTU (Mbrtu), 38,400 baud, address 247. (Note:These are the factory default settings.) 5. Create a new file (File, New) or open an existing PAXI V3.0+ database. 6. Configure Crimson Link options (Link, Options) to the serial port which the communication cable is attached (in step 2). SUPPORTED FUNCTION CODES FC03: Read Holding Registers 1. Up to 64 registers can be requested at one time. 2. HEX <8000> is returned for non-used registers. FC04: Read Input Registers 1. Up to 64 registers can be requested at one time. 2. Block starting point can not exceed register boundaries. 3. HEX <8000> is returned in registers beyond the boundaries. 4. Input registers are a mirror of Holding registers. FC06: Preset Single Register 1. HEX <8001> is echoed back when attempting to write to a read only register. 2. If the write value exceeds the register limit (see Register Table), then that register value changes to its high or low limit. It is also returned in the response. FC16: Preset Multiple Registers 1. No response is given with an attempt to write to more than 64 registers at a time. 2. Block starting point cannot exceed the read and write boundaries (40001- 41280). 3. If a multiple write includes read only registers, then only the write registers will change. 4. If the write value exceeds the register limit (see Register Table), then that register value changes to its high or low limit. FC08: Diagnostics The following is sent upon FC08 request: Module Address, 08 (FC code), 04 (byte count), “Total Comms” 2 byte count, “Total Good Comms” 2 byte count, checksum of the string “Total Comms” is the total number of messages received that were addressed to the PAXI. “Total Good Comms” is the total messages received by the PAXI with good address, parity and checksum. Both counters are reset to 0 upon response to FC08 and at power-up. FC17: Report Slave ID The following is sent upon FC17 request: <a> = SP Card Status. “0”-None, “2”-Dual, “4”-Quad <b> = Linear Card Status. “0”-Not Installed, “1”-Installed <0300h> = Software Version Number (e.g. 3.00) <0040h><0040h> = Max Register Reads/Writes (64) <0010h> = Number of GUID/Scratch Pad Registers (16) SUPPORTED EXCEPTION CODES 01: Illegal Function Issued whenever the requested function is not implemented in the meter. 02: Illegal Data Address Issued whenever an attempt is made to access a single register that does not exist (outside the implemented space) or to access a block of registers that falls completely outside the implemented space. 03: Illegal Data Value Issued when an attempt is made to read or write more registers than the meter can handle in one request. 07: Negative Acknowledge Issued when a write to a register is attempted with an invalid string length. PAXI MODBUS REGISTER TABLE This table shows the most commonly used registers for the PAXI. The complete register table listing is available at http://www.redlion.net. Values less than 65,535 will be in (Lo word). Values greater than 65,535 will continue into (Hi word). Negative values are represented by two’s complement of the combined (Hi word) and (Lo word). The PAXI should not be powered down while parameters are being changed. Doing so may corrupt the non-volatile memory resulting in checksum errors.

SENDING SERIAL COMMANDS AND DATA TO THE METER When sending commands to the meter, a string containing at least one command character must be constructed. A command string consists of a command character, a value identifier, numerical data (if writing data to the meter) followed by a command terminator character * or $. The <CR> is also available as a terminator when Counter C is in the SLA VE mode. Command Chart COMMAND DESCRIPTION NOTES N Node (Meter) Address Specifier Address a specific meter. Must be followed by a two digit node address. Not required when address = 00. T Transmit Value (read) Read a register from the meter. Must be followed by register ID character V Value Change (write) Write to register of the meter. Must be followed by register ID character and numeric data. R Reset Reset a register or output. Must be followed by register ID character. P Block Print Request Initiates a block print output. Registers are defined in programming. Command String Construction The command string must be constructed in a specific sequence. The meter does not respond with an error message to invalid commands. The following procedure details construction of a command string: 1. The first characters consist of the Node Address Specifier (N) followed by a 1 or 2 character address number. The address number of the meter is programmable. If the node address is 0, this command and the node address itself may be omitted. For node address 1 through 9, a leading zero character is not required. (The only exception is a numeric transmission when Counter C is set for slave mode.) This is the only command that may be used in conjunction with other commands. 2. After the optional address specifier, the next character is the command character. 3. The next character is the Register ID. This identifies the register that the command affects. The P command does not require a Register ID character. It prints according to the selections made in print options. 4. If constructing a value change command (writing data), the numeric data is sent next. 5. All command strings must be terminated with the string termination characters *, $ or when Counter C is set for slave mode <CR>. The meter does not begin processing the command string until this character is received. See Timing Diagram figure for differences between terminating characters. Sending Numeric Data Numeric data sent to the meter must be limited to the digit range shown under transmit details in the Register Identification Chart. Leading zeros are ignored. Negative numbers must have a minus sign. The meter ignores any decimal point and conforms the number to the scaled resolution. (For example: the meter’s scaled decimal point position = 0.0 and 25 is written to a register. The value of the register is now 2.5. Note: Since the meter does not issue a reply to value change commands, follow with a transmit value command for readback verification.

COUNTER C SLAVE COMMUNICATIONS Counter C may be programmed for , to act as a serial slave display. By doing this, the carriage return <CR> is added as a valid command terminator character for all serial command strings. The <CR> as a terminator may be very useful for standard serial commands, even if Counter C is never displayed or sent a slave message. The $ terminator should not be used in the slave mode. If numeric values are not to be saved to memory, then send the value as a literal transmission with <CR> terminator. The Counter C slave display is right aligned. It has a capacity of displaying six characters. When less than six characters are received, blank spaces will be placed in front of the characters. If more than six characters are sent, then only the last six are displayed. The meter has a 192 character buffer for the slave display. If more than 192 characters are sent, the additional characters are discarded until a terminator is received. Counter C processes numeric and literal transmissions differently. Numeric Transmissions When a string that does not begin with #, T, V , P or R is received, the meter processes it as a Numeric transmission. In this case, only the recognized numbers and punctuation are displayed. All other characters in the string are discarded. If a negative sign appears anywhere in the string the resulting number will be negative. Only the most significant decimal point is retained. If no numerical characters are received, then the numeric value will be zero. The numeric display can be used for setpoint (boundary action only) and analog output functions. When using this display for setpoint and analog output values, the decimal point position must match the programming entered through the front panel. The numeric value is retained in Counter C memory until another Numeric transmission is received. Recognized Numbers = 0, 1, 2, 3, 4, 5, 6, 7, 8, 9 Recognized Punctuation = period, comma, minus Literal Transmissions When a string that begins with # is received, the meter processes it as a Literal transmission. In this case, any unrecognized characters will be replaced with a space. A Literal display will replace a Numeric value in the Counter C display. However, it will not remove a previous Numeric value from Counter C memory or prevent the Counter C outputs from functioning with the Numeric value. Literal transmissions are only possible when using RS232 or RS485 cards. Recognized Characters = a, b, c, d, e, f, g, h, i, j, l, n, o, p, q, r, s, t, u, y, z (in upper or lower case) Recognized Numbers = 0, 1, 2, 3, 4, 5, 6, 7, 8, 9 Recognized Punctuation = period, comma, minus, blank RECEIVING DATA FROM THE METER Data is transmitted by the meter in response to either a transmit command (T), a print block command (P) or User Function print request. The response from the meter is either a full field transmission or an abbreviated transmission. The meter response mode is established in Module 7. Full Field Transmission (Address, Mnemonic, Numeric data) Byte Description 1, 2 2 byte Node (meter) Address field [00-99] 3 <SP> (Space) 4-6 3 byte Register Mnemonic field 7-18 12 byte data field, 10 bytes for number, one byte for sign, one byte for decimal point 19 <CR> carriage return 20 <LF> line feed 21 <SP>* (Space) 22 <CR>* carriage return 23 <LF>* line feed * These characters only appear in the last line of a block print. The first two characters transmitted (bytes 1 and 2) are the unit address. If the address assigned is 00, two spaces are substituted. A space (byte 3) follows the unit address field. The next three characters (bytes 4 to 6) are the register mnemonic. The numeric data is transmitted next. The numeric field (bytes 7 to 18) is 12 characters long. When the requested value exceeds eight digits for count values or five digits for rate values, an * (used as an overflow character) replaces the space in byte 7. Byte 8 is always a space. The remaining ten positions of this field (bytes 9 to 18) consist of a minus sign (for negative values), a floating decimal point (if applicable), and eight positions for the requested value. The data within bytes 9 to 18 is right-aligned with leading spaces for any unfilled positions. The end of the response string is terminated with <CR> (byte 19), and <LF> (byte 20). When a block print is finished, an extra <SP> (byte 21), <CR> (byte 22), and <LF> (byte 23) are used to provide separation between the transmissions. Abbreviated Transmission (Numeric data only) Byte Description 1-12 12 byte data field, 10 bytes for number, one byte for sign, one byte for decimal point 13 <CR> carriage return 14 <LF> line feed 15 <SP>* (Space) 16 <CR>* carriage return 17 <LF>* line feed * These characters only appear in the last line of a block print. Meter Response Examples: 1. Address = 17, full field response, Count A = 875

- Address = 0, full field response, Setpoint 2 = -250.5 SP2 -250.5<CR><LF> 3. Address = 0, abbreviated response, Setpoint 2 = 250, last line of block print AUTO/MANUAL MODE REGISTER (MMR) ID: U This register sets the controlling mode for the outputs. In Auto Mode (0) the meter controls the setpoint and analog output. In Manual Mode (1) the outputs are defined by the registers SOR and AOR. When transferring from auto mode to manual mode, the meter holds the last output value (until the register is changed by a write). Each output may be independently changed to auto or manual. In a write command string (VU), any character besides 0 or 1 in a field will not change the corresponding output mode. U abcde e = Analog Output d = SP4 c = SP3 b = SP2 a = SP1 Example: VU00011* places SP4 and Analog in manual. ANALOG OUTPUT REGISTER (AOR) ID: W This register stores the present signal value of the analog output. The range of values of this register is 0 to 4095, which corresponds to the analog output range per the following chart: Register Value Output Signal* 0-20 mA 4-20 mA 0-10 V 0 0.00 4.00 0.000 1 0.005 4.004 0.0025 2047 10.000 12.000 5.000 4094 19.995 19.996 9.9975 4095 20.000 20.000 10.000 Writing to this register (VW) while the analog output is in the Manual Mode causes the output signal level to update immediately to the value sent. While in the Automatic Mode, this register may be written to, but it has no effect until the analog output is placed in the manual mode. When in the Automatic Mode, the meter controls the analog output signal level. Reading from this register (TW) will show the present value of the analog output signal. Example: VW2047* will result in an output of 10.000 mA, 12.000 mA or 5.000V depending on the range selected. SETPOINT OUTPUT REGISTER (SOR) ID: X This register stores the states of the setpoint outputs. Reading from this register (TX) will show the present state of all the setpoint outputs. A “0” in the setpoint location means the output is off and a “1” means the output is on. X abcd d = SP4 c = SP3 b = SP2 a = SP1 In Automatic Mode, the meter controls the setpoint output state. In Manual Mode, writing to this register (VX) will change the output state. Sending any character besides 0 or 1 in a field or if the corresponding output was not first in manual mode, the corresponding output value will not change. (It is not necessary to send least significant 0s.) Example: VX10* will result in output 1 on and output 2 off. *Due to the absolute accuracy rating and resolution of the output card, the actual output signal may differ 0.15% FS from the table values. The output signal corresponds to the range selected (0-20 mA, 4-20 mA or 0-10 V).
Data is transferred from the meter through a serial communication channel. In serial communications, the voltage is switched between a high and low level at a predetermined rate (baud rate) using ASCII encoding. The receiving device reads the voltage levels at the same intervals and then translates the switched levels back to a character. The voltage level conventions depend on the interface standard. The table lists the voltage levels for each standard. Data is transmitted one byte at a time with a variable idle period between characters (0 to ∞). Each ASCII character is “framed” with a beginning start bit, an optional parity bit and one or more ending stop bits. The data format and baud rate must match that of other equipment in order for communication to take place. The figures list the data formats employed by the meter. Start bit and Data bits Data transmission always begins with the start bit. The start bit signals the receiving device to prepare for reception of data. One bit period later, the least significant bit of the ASCII encoded character is transmitted, followed by the remaining data bits. The receiving device then reads each bit position as they are transmitted. Parity bit After the data bits, the parity bit is sent. The transmitter sets the parity bit to a zero or a one, so that the total number of ones contained in the transmission (including the parity bit) is either even or odd. This bit is used by the receiver to detect errors that may occur to an odd number of bits in the transmission. However, a single parity bit cannot detect errors that may occur to an even number of bits. Given this limitation, the parity bit is often ignored by the receiving device. The PAX meter ignores the parity bit of incoming data and sets the parity bit to odd, even or none (mark parity) for outgoing data. Stop bit The last character transmitted is the stop bit. The stop bit provides a single bit period pause to allow the receiver to prepare to re-synchronize to the start of a new transmission (start bit of next byte). The receiver then continuously looks for the occurrence of the start bit. If 7 data bits and no parity is selected, then 2 stop bits are sent from the PAXI.

- Voltage levels at the Receiver COMMAND RESPONSE TIME The meter can only receive data or transmit data at any one time (half-duplex operation). During RS232 transmissions, the meter ignores commands while transmitting data, but instead uses RXD as a busy signal. When sending commands and data to the meter, a delay must be imposed before sending another command. This allows enough time for the meter to process the command and prepare for the next command. At the start of the time interval t1, the computer program prints or writes the string to the com port, thus initiating a transmission. During t 1, the command characters are under transmission and at the end of this period, the command terminating character (*, $ or slave only <CR>) is received by the meter. The time duration of t 1 is dependent on the number of characters and baud rate of the channel. t1 = (10 times the # of characters) / baud rate At the start of time interval t 2, the meter starts the interpretation of the command and when complete, performs the command function. This time interval t 2 varies from 2 msec to 15 msec. If no response from the meter is expected, the meter is ready to accept another command. If the meter is to reply with data, the time interval t 2 is controlled by the use of the command terminating character and the Serial Transmit Delay parameter (dELAY). The ‘*’ or ‘<CR>’ terminating character results in a response time window of the Serial Transmit Delay time (dELAY) plus 15 msec. maximum. The dELAY parameter should be programmed to a value that allows sufficient time for the release of the sending driver on the RS485 bus. Terminating the command line with “$” results in a response time window (t2) of 2 msec minimum and 15 msec maximum. The response time of this terminating character requires that sending drivers release within 2 msec after the terminating character is received. At the beginning of time interval t 3, the meter responds with the first character of the reply. As with t 1, the time duration of t 3 is dependent on the number of characters and baud rate of the channel. At the end of t3, the meter is ready to receive the next command. t3 = (10 times the # of characters) / baud rate The maximum serial throughput of the meter is limited to the sum of the times t1, t2 and t3.

The Count A and B values are scaled using the parameters in Module 1, Counter C value is scaled using Module 5 and the Rate value is scaled using Module 4. If the meter appears to be indicating incorrectly or inaccurately, refer to the Troubleshooting section. When Analog Out recalibration is required (generally every 2 years), it should be performed by qualified technicians using appropriate equipment. Calibration does not change any user programmed parameters. Calibration may be aborted by disconnecting power to the meter before exiting Module 9. In this case, the existing calibration settings remain in effect. Note: Allow a 30 minute warm-up period before staring calibration. Shaded areas are model dependent. INPUT A AND B LOGIC SELECTION The Count Inputs A and B are factory configured for falling edge triggered (active low) operation in single edge count modes. The Counter Operating Mode descriptions in the Input programming section reflect this logic. If an application is better suited to use rising edge triggered (active high) operation, the Input Logic for Input A and/or Input B can be changed by entering Code 55. Selecting sets the Input A logic to rising edge triggered (active high) operation. Be advised that all references to Input A falling edge and Input A rising edge will be reversed for the Counter Operating Mode descriptions. Selecting sets the Input B logic to rising edge triggered (active high) operation. Be advised that all references to Input B falling edge and Input B rising edge will be reversed for the Counter Operating Mode descriptions. The meter briefly displays the unit type followed by the current firmware version ( x.x), and then returns to . This information is also displayed during the meter power-up sequence.
