Default I/O diagram of the supply control unit [A51]
The diagram below shows the default I/O connections on the supply control unit [A51], and
describes the use of the signals/connections in the supply unit. Under normal
circumstances, the factory-made wiring should not be changed.
Relay outputs
XRO1: Running (energized = running)
250 V AC / 30 V DC

Safe torque off. Both circuits must be closed for the supply unit to start.
(IN1 and IN2 must be connected to OUT.)
Digital inputs
Temperature fault (0 = overtemperature)
Run / enable (1 = run enable)
MCB feedback (1 = main contactor/breaker closed)
Circuit breaker fault (0 = auxiliary circuit breaker or switch open)
Ground (earth) fault (1 = ground fault monitoring tripped)
Reset (0 -> 1 = fault reset)
Emergency stop (0 = emergency stop activated) (units with em. stop option only)
