To test the 4-20mA input on the Krom Schroder IC 20 actuator:
1. Check Wiring: - Ensure the analogue input (IN Analog) is correctly wired for 4-20mA. - Verify polarity: incorrect polarity can cause malfunction.
2. Set DIP Switches: - Configure the DIP switches according to the input signal requirements. - Refer to page 7 of the manual for the correct DIP switch settings.
3. Verify Input Signal: - Use a multimeter or signal generator to provide and measure the 4-20mA signal. - Ensure the input signal is between 4-20mA; if below 3mA, the red LED will flash once.
4. Check Feedback Potentiometer (if installed): - The potentiometer must be used as a voltage divider. - Measure voltage changes corresponding to actuator position.
5. Monitor LED Indicators: - If the adjustment range is too small, the red LED will flash three times. - Adjust the range using the min and max buttons if needed.
6. Test Actuator Response: - The actuator should move according to the 4-20mA signal. - If the actuator does not respond, check wiring, DIP switch settings, and input signal.
This ensures proper functionality and testing of the 4-20mA input on the IC 20 actuator.
