2 Digital Indicators K3HB Series (Pulse Input Series)

Many I/O Variations for Discrimination, Control, and Information Applications Digital Indicators are used in a wide variety of applications, from an electronic measurement value display or equipment/device operating status display to a host communications interface in monitoring and control systems. OMRON provides a complete lineup for a variety of input and control output applications to meet all your application requirements. Select a Comparative Output Pattern to Suit the Discrimination or Control Application

The output pattern for comparative outputs can be selected. In addition to high/low comparison with set values, output based on level changes is also possible. (Use the type of output pattern appropriate for the application.) Note: The HH, H, L or LL outputs must be set in that order for the zone outputs to output correctly. (This is because the comparative set values and outputs for standard and level outputs are in a 1-to-1 relationship, whereas the meaning of zone outputs depends on the settings of all the comparative set values.) Lineup Includes DeviceNet Models Enabling High-speed Data Communications with PLCs without Special Programming DeviceNet compliance enables high-speed data transmission by allocating setting and monitoring parameters in the I/O memory of the PLC. This capability greatly reduces labor spent in developing communications programs. N/C NPN PNP Sensor power supply (CPB) (CPA)

Rotary Pulse Indicator K3HB-R 7 Operation ■Functions (Operating Modes) F1 to F6 Functions F1 to F6 provide rpm/circumferential speed and other calculation displays by measuring continuous pulses (frequencies ). Example Function name Function No. Rpm/circumferential speed Absolute ratio f2 Error ratio f3 Rotational difference f4 Flow rate ratio f5 Passing time f6 Length of processing stage F1: Displays rotation (rpm) or circumferential speed for one input. F2 to F5: Displays the calculation result for two rotation (rpm) speeds. F6: Displays the passing time calculated from the circumferential speed and the length of the processing stage for one input. The basic principle used by the Digital Indicator to calculate the rotation speed (rpm) display is to count the ON/OFF time (T) for input sensor or other device inputs using the internal system clock, and then automatically calculate the frequency. This frequency (f) is multiplied by 60 and displayed as the rotation (rpm) speed. Input sensor or other input pulse ON/OFF time (T) = Frequency (f) = Rotation speed (rpm) = f × 60 Circumferential speed = Roll circumference × Rotation speed (rpm) Passing time= These calculations are automatically made internally and displayed whenever any input pulse is received.

Rotary Pulse Indicator K3HB-R 9 ■What Is Prescaling? To make calculations using the input pulse to display rotation (rpm) or circumferential speed, the number of pulses per rotation or the length of the circumference must be multiplied by a certain coefficient. This coefficient is called the prescale value. Rotation speed (rpm) = f × 60 × a f: Input pulse frequency (No. of pulses per second) a: Prescale value If there are 5 pulses per rotation, then and an accurate rotation speed (rpm) can be calculated. The actual setting is X = 2.0000 (mantissa) and Y = 10 -1 (exponent). ■What Is the Auto-zero Function? (Set this function before using the Digital Indicator.) If a function f1 to f6 is set, the frequency can be force-set to zero if there is no input pulse for a set period. This period is called the auto- zero time. Set the auto-zero time to slightly longer than the longest input pulse interval. (The display will not easily return to zero if the auto-zero time is too long or left at the default setting.) Time Unit Settings Note: Time unit can be set only when passing time (F6) is selected. Input Type Setting Note: Set to 10 or 11 when there is a large variation in the display. The largest measurement range is 30 Hz.

■What Is Prescaling? To make calculations using the input pulse to display the passing speed between two points, the distance between the two points and the display unit must be set and the internally measured time multiplied by a certain coefficient. This coefficient is called the prescale value. (For information on settings details, refer to the User's Manual.) Time Unit Settings Input Type Setting Note: Set to 10 or 11 when there is a large variation in the display. The largest measurement range is 30 Hz. Time band Displays input A ON time (T).

Prevents comparative outputs from chattering when the measurement value fluctuates slightly near the set value. Holds the output status when a comparative result output other than PASS turns ON. Comparative results other than PASS and error signals can be output from the PASS output terminal. Delays turning OFF comparatives for a set period. This can be used to provide sufficient time to read the comparative output ON status when the comparative result changes at short intervals. Turns ON the comparative output for a specific time. Reverses the output logic of comparative results. Measurements can be stopped for a set time using an external input. Output operation can be checked without using actual input signals by using the keys to set a test measurement value. A current or voltage proportional to the change in the measurement value can be output. The comparison outputs can be kept OFF until the measurement value enters the PASS range. Display The display value can be set to the present value, the maximum value, or the minimum value. The present value display color can be set to green or red. The color of the present value can also be switched according to the comparative output. When the input changes rapidly, the display refresh period can be lengthened to control flickering and make the display easier to read. The present measurement value can be displayed as a position in relation to the scaling width on a 20-gradation position meter. The input signal can be converted and displayed as any value. Select whether or not to display the comparative value during operation. Automatically returns the display to RUN level when there are no key Other Holds the maximum and minimum measurement values.
