system, the current load of the
current paths of the DC 24 V standby supply
voltage inside the device is too high. The device
signal output of the device was de-energized be-
cause of the fault message.
Identify the consumer that is overloading the in-
ternal supply voltage:
1. Remove all external consumers:
– At the digital outputs of the basic unit.
– At options that may be present.
– At all encoder connections.
– At other consumers at the DC 24 V output
voltage terminals.
2. Acknowledge the fault.
3. Reconnect the consumers to the device one
after the other until the fault message appears
again.
4. To eliminate the fault, connect a consumer with
a lower current consumption or eliminate the
short circuit.
