Digital Controller E5AK/E5EK 21 ■Parameter Initialize Parameter initialization sets all parameters to default values except for the input type, scaling upper limit, scaling lower limit, decimal point, and °C/°F selection parameters. ■Output Assignments Signals available as allocated outputs are the control output (heat), control output (cool), alarm 1, alarm 2, alarm 3, LBA, and HBA. The auxiliary outputs of the Digital Controller cannot be used as control outputs. Control output (heat), control output (cool), alarm 1, alarm 2, alarm 3, LBA, error 1 (input error), error 2 (A/D converter error), and error 3 (RSP input error) output functions are available. These functions are assigned to control outputs 1 and 2 and auxiliary outputs 1 and 2. The assignment destination of each output function is may be restricted. Refer to the following table. Standard Models In other words, heating and cooling control is carried out when con- trol output (cool) is assigned, and standard control is carried out when output is not assigned. Position-proportional Models LBA The LBA (loop break alarm) function is available when it is assigned as an output. The LBA function is not available when a memory or A/ D converter error results. LBA is a function for determining that an error has occurred some- where on the control loop and outputting an alarm when the process value does not change with the manipulated variable at a maximum or minimum state. Accordingly, the LBA function can be used as a means for detecting a malfunctioning control loop.

When set to “open in alarm,” the sta- tus of the alarm output function is output inverted. Alarm type and close in alarm (normally open)/open in alarm (nor- mally close) can be set independently from each alarm. Close in alarm/Open in alarm is set in the “alarm 1 to 3 open in alarm” parameters (setup mode). Factor y setting is “close in alarm” [ n-o ]. ■Parameter Operation List Switching to modes other than manual or protect mode is carried out using the mode selection in the menu display. The figure below shows all parameters in the order that they are displayed. Some parameters are not displayed depending on the protect mode setting and conditions of use. ■Parameters and Menus Note: For more details on the functions of each part and display contents, refer to the E5AK/E5EK User’s Manual (H83/H85). All functions selected with the Digital Controller in setup or expansion mode or all optional functions of the Digital Controll er may not be displayed. Protect Mode Limits use of the menu and A/M Keys. The protect function prevents unwanted modification of parameters and switching between the auto and manual operation.

Level 0 Mode Set the Controller to this mode during normal operation. In this mode, change the set point during operation, and start or stop Controller operation. The process value, ramp SP , and manipulated variable can only be monitored in this mode. Level 1 Mode The main mode for adjusting control. In this mode, execute AT (auto-tuning), and set alarm values, the control pe- riod, and PID parameters. Level 2 Mode The auxiliary mode for adjusting control. In this mode, set the parameters for limiting the manipulated variable and set point, switch between the remote and local modes, switch between the SP mode, and set the loop break alarm (LBA), alarm hysteresis, and the digital filter value of inputs. Setup Mode The mode for setting the basic specifications. In this mode, set parameters that must be checked or set before operation such as the input type, scaling, output assignments and direct/reverse operation. Expansion Mode The mode for setting expanded functions. In this mode, set ST (self-tuning), SP setting limiter, select advanced PID or ON/OFF control, specify the standby sequence resetting method, and set the time for automatic return to the monitoring display. Option Mode The mode for setting option functions. Select this mode only when the Option Unit is set in the Controller. In this mode, set the communications conditions, transfer output and event input parameters to match the type of Option Unit set in the Controller. Heater burnout latch function, position-proportional travel time, and remote SP scaling parameter are also located in this mode. Calibration Mode The mode for calibrating inputs and transfer output. When calibrating input, the selected input type is calibrated. Whereas, transfer output can be calibrated only when the Communications Unit (E53-CKF) is set in the Controller. ■Parameter Operation Refer to the E5AK/E5EK User’s Manual (H83/H85) for each parameter and the calibration mode in detail. Refer to page 9 for the setting in detail. Level 0 Mode PV/SV The process value is displayed on the No.1 display and the set point is displayed on the No.2 display. When the multi-SP function is in use, the value of whichever is set, set point 0 or 1, is linked. Remote SP Monitor Monitors remote SP in the local SP mode. Set Point During SP Ramp Monitors the set point when the SP ramp function is used. SP Ramp With the SP ramp function, the Controller operates according to the value (set point during SP ramp) limited by a change rate, instead of the changed set point when the set point is changed. The interval in which the set point during SP ramp is limited is referred to as the “SP ramp.” The change rate during the SP ramp is specified by the “SP ramp set value” and “SP ramp time unit” parameters. At the “SP ramp set value” default “0,” the SP ramp function is disabled. The set point changing in SP ramp can be monitored in the “Set point during SP ramp” parameter (level 0 mode).

Digital Controller E5AK/E5EK 27 Input Shift When temperature input is selected, scaling is not required. This is because input is treated as the “temper ature” as it is matched to the input type. However, note that the upper- and lower-limit values of the sensor can be shifted. For example, if both the upper- and lower-limit values are shifted by 1.2 °C, the process value (before shift) is regarded as 201.2°C after shift when input is 200°C before shift. To set the input shift, set shift values in the “input shift upper limit” and “input shift lower limit” parameters (level 2 mode).

Digital Controller E5AK/E5EK 29 ■How to Use the Error Display When an error has occurred, the No.1 display alternately indicates error codes together with the current display item. This section describes how to check error codes on the displa y, and the actions that must be taken to remedy the problem. Meaning Input is in error. Action Check the wiring of inputs, disconnections, and shorts, and check the input type and the input type jumper con- nector. Operation at Error For control output functions, output the manipulated variable matched to the setting of the “MV at PV error” param- eter (level 2 mode). Alarm output functions are activated when the upper limit is exceeded. Meaning Internal memory operation is in error Action First, turn the power OFF then back ON again. If the display remains the same, the E5AK/E5EK Controller must be repaired. If the display is restored to normal, the probable cause may be external noise affecting the control system. Check for external noise. Operation at Error Control output functions turn OFF (2 mA max. at 4 to 20 mA output, and output equivalent to 0% in case of other outputs). Alarm output functions turn OFF . Meaning Internal circuits are in error. Action First, turn the power OFF then back ON again. If the display remains the same, the E5AK/E5EK Controller must be repaired. If the display is restored to normal, the probable cause may be external noise affecting the control system. Check for external noise. Operation at Error Control output functions turn OFF (2 mA max. at 4 to 20 mA output, and output equivalent to 0% in case of other outputs). Alarm output functions turn OFF . This error is output only during temperature input and is displayed for two seconds when the power is turned ON. Meaning Calibration data is in error. Action Must repair. Operation at Error Both control output functions and alarm output functions are active. However, note that the readout accuracy is not assured. Meaning Though not an error, this is displayed when the proces s value exceeds the display range when the control range (setting range ±10%) is larger than the display range (−1999 to 9999).  When less than “−1999”  When greater than “9999” Operation Control continues, allowing normal operation. Input Error Memory Error A/D Converter Error Calibration Data Error Display Range Over

30 Digital Controller E5AK/E5EK

Meaning Motor calibration has ended with an error. Action First, correctly connect the wiring for the potentiometer, open output, and close output. Execute the motor calibration again. Operation Procedure Operation at Error When motor calibration is executed, open output will oper ate and then close output will operate. However, as the value is incorrect, the result turns out to be an error. Motor Calibration Error (Displayed on the No. 2 Display)

Digital Controller E5AK/E5EK 31 ■Fuzzy Self-tuning Fuzzy self-tuning is a function that enables the E5AK/E5EK to calcu- late the most suitable PID constants for the controlled object.

Features

 The E5AK/E5EK determines by itself when to perform fuzzy self- tuning. Fuzzy Self-tuning Function The fuzzy self-tuning function has three modes. In SRT (step response tuning) mode, the PID constants are tuned using a step response method at the time the set point is changed. In DT (disturbance tuning) mode, the PID constants are amended so that the controlled temperat ure will be within the target range set in advance when there is external disturbance. In HT (hunting tuning) mode, when hunting occurs, the PID con- stants are amended to suppress the hunting. Note: Be sure to turn on the power supply to the load either before or simultaneously with the start of Temperature Controller opera- tion. Dead time will be measured from the time the Temperature Controller starts operating. If a load such as a heater is turned on after the Temperature Controller is turned on, dead time longer than the actual value will be measured and inappropri- ate PID constants will be obtained. If an extremely large amount of dead time is measured, the control amount will be set to 0% for a short period of time before being returned to 100%, and the constants will then be retuned. Retuning is per- formed only for large amounts of dead time, so be sure to follow the precaution given above when starting operation. Startup Conditions of SRT SRT will start if the following conditions are satisfied simultaneously when the E5AK/E5EK is turned on or the set point is changed. Note: The last SRT -executed set point is set to 0 before shipping and when changing from advanced PID control to advanced PID control with fuzzy self-tuning. PID Constant Refreshing Conditions If the step control amount is applied before the maximum tempera- ture slope (R) is obtained, SRT will not renew any PID constant. If the proportional band obtained from the R and L values that were mea- sured before the imposition had been completed is larger than the present proportional band, the PID constants will be renewed because the measured value is in the direction towards the suitable proportional band value, and the set point at that time will be the SRT -executed set point. Stable Temperature Status If the temperature is within the stable range for a certain time, it is deemed that the temperature is stable. This time is called stability judgement time. Like PID constants, stability judgement time is adjusted with fuzzy self-tuning according to the characteristics of the object to be controlled. Fuzzy self-tuning will not be activated if the temperature is stable because the Temperature Controller deems that temperature control is smooth. Balanced Status If the process value is within the stable range for 60 s when there is no output, it is deemed that the temperature is balanced. Startup Conditions of DT 1. DT will start if the temperature that has been stable varies due to external disturbance and the deflection of the temperature exceeds the stable range, and then the temperature becomes stable, provided that the number of maximum temperature values is less than four. 2. DT will start if the set point is changed under the condition that SRT does not start and the temperature becomes stable, pro- vided that the number of maximum temperature values is less than four. If there are four or more maximum temperature values, HT will start. At the time the E5AK/E5EK starts operating At the time set point is changed 1. The set point at the time the E5AK/E5EK starts operating is different from the set point used at the time SRT was last executed (see note). 2. The process value at the time the E5AK/E5EK starts operat- ing is smaller than the set point in reverse operation and larger than the set point in normal operation. 1. The new set point is different from the set point used at the time SRT was last executed (see note). 2. The process value is in stable condition before the set point is changed. 3. A larger set point value is set in reverse operation and a smaller set point is set in nor- mal operation.

HT will be ON when there is hunting with four or more maximum tem- perature values (extreme values) while SRT is not being executed. Note: In specific applications where temperature varies periodically due to disturbance, internal parameters need to be adjusted. For details, refer to the E5AK/E5EK User’s Manual (H83/H85).

Keep within the rated ambient operating temperature, ambient oper- ating humidity, and storage temperature ranges. Use the Unit according to the vibration resistance, shock resistance, and degree of protection. Do not use the Unit in places with corrosive gas or excessive dust. Do not use the Unit nearby machines generating high-frequency noise. Correct Use Mounting The dimensions of the Digital Controller conform to DIN 43700. Recommended panel thickness is 1 to 8 mm. Mount the Unit horizontally. Connection To reduce inductive noise influence, the lead wires connecting the input type to the Digital Controller must be separated from the power lines and load lines. Use the specified compensating c onductors for thermocouples. Use lead wires having a small resistance for platinum resistance ther- mometers. Connection Example Wire the terminals of the Unit using solderless terminals. The tightening torque applied to the terminal screws of the Unit must be approximately 0.78 N·m or 8 kgf·cm. Use the following type of solderless terminals for M3.5 screws. Operation The alarm outputs of a model with an alarm function may not turn ON properly when the model malfuncti ons. The use of alarm equipment with the model is recommended. The parameters and internal switch are set before shipping so that the Unit will function normally. Change the settings of the parameters and internal switch according to the application if necessary. Several seconds are required until the relay is turned ON after power has been supplied to the Digital Controller. Therefore, take this time delay into consideration when designing sequenced circuits which incorporate a Digital Controller. Do not use excessive force when drawing out the internal mecha- nism from the housing. Protect the internal connector or electronic parts of the Unit from shock. Protect against static discharge when changing the settings of the internal switch. Changing the settings on a grounded conductive mat is recommended. When connecting the Control Output Unit to the Temperature Con- troller or Digital Controller, make sure that the Control Output Unit is a suitable type. The use of an improper type of Control Output Unit may cause the system to malfunction. The heater burnout alarm will not be available if the Linear Output Unit is used. 7.2 mm max. 7.2 mm max.
