Power Up and Test
Restore power to the circuit. The BUS POWER LEVEL LED will display green
when auxiliary power is present.
If a fault is discovered in the control wiring, the BUS POWER LEVEL LED will
turn off and the FAULT indicator will illuminate. This condition typically means
that the station wiring has a fault; however it could mean a connected device
is having an issue. A qualified technician should inspect the system wire and
terminations first, and then proceed to disconnecting devices to pinpoint the
fault and correct it.
The DIN Rail Station Power Supply will update the fault indicator
automatically when the fault condition is cleared.
