TROUBLESHOOTING
PROBLEM SOLUTION(S)
No Reading:
- Verify that there is current flowing through the conductor being monitored with a
clamp-on current probe.
- Check the polarity of the circuit.
- Verify that the terminals are screwed down, wires are firmly in place.
MSCTA-40
- Confirm that you have +13.5 to 30VDC in series with the current sensor output
terminals and the analog input of the control panel.
- Disconnect the input to the control panel and then insert a current meter (mA
range) in series with the current sensor output to verify that the circuit is working
properly.
MSCTE-40
- No power supply needed. The power for the current sensor is induced from the
conductor being monitored.
- Disconnect the wires from the current sensor output and tighten down the screws.
Measure the voltage across the current sensor output with a Voltmeter to verify that
the sensor is working properly.
Erratic Readings:
- Verify that the wires are terminated properly.
- In areas of high RF interference, shielded
cable may be necessary to stabilize signal.
Inaccurate Readings:
- If you suspect that the current sensor is not reading within the accuracy
specifications, please contact the factory for assistance.
Current Sensor is operating at a low-level
current or failing to operate within the accuracy
specifications:
-Visually check the mating parts of the core to ensure there is no debris between the
split contacts.
-Remove all debris or dust manually and close the current sensor.
-Continue to retest the sensor in your application.
