Troubleshooting
Problem
Solution
LED is on but the current switch didn’t activate Disconnect the wires from the current switch output. Measure the resistance
across the contacts with an Ohmmeter.
See Figure 6
for the actual resistance
readings for an open or closed switch reading.
LED didn’t turn on and the current switch
didn’t activate
Verify that the current flowing in the conductor being monitored is above the
fixed trip point as listed in the operating specifications. If the sensor is
monitoring less than the fixed trip point
See Figure 3
.
LED not on but the Current Switch is Activated LED not indicating correctly, may have been damaged
Current Switch is operating at a low-level
current or failing to operate within the accuracy
specifications.
For A/SCS2 Series, 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,
See Figure 2
. Retest the sensor in your application.
