Performing a reset of the VDC power supply

Perform a reset of the power supply if the input of the VDC power is receiving power, but 24 VDC is
not present at the output. In that case, the DC OK LED will be off.
1. Switch the Compass system off with the circuit breaker.
2. Wait 30 seconds.
3. Switch the Compass system on with the circuit breaker.
4. Check whether the DC OK LED is on.
If the LED is not on, the 24 VDC power supply is defective or there is a short circuit in the system.
To determine if there is a short circuit and to find its source:
1. Switch the Compass system off with the circuit breaker.
2. Disconnect all 24 VDC common wires from the 24 VDC connecting terminals.
3. Switch the Compass system on with the circuit breaker.
4. Check whether the DC OK LED is on.
If the DC OK LED is off, the power supply is defective. Replace the power supply.
If the DC OK LED is on, there is a short circuit in the system. Continue with the next step to find
the source.
5. Connect the 24 VDC common wires to the connecting terminals one by one.
6. Check the DC OK LED after connecting each wire.
If the DC OK LED stays on after you have connected a wire, this wire does not cause a short
circuit.
If the DC OK LED goes out after you have connected a wire, this wire causes the short circuit.
7. Resolve the short circuit.
8. Switch the Compass system off with the circuit breaker.
9. Reconnect all wiring.
10. Switch the Compass system on with the circuit breaker.
