Faults – Interference
By closing or interrupting the input circuit you can check whether the unit switches on or off
correctly.
For safety reasons, the unit cannot be started if the following faults are present:
} Contact malfunction: As the contact block is connected to a base unit,
reactivation will not be possible if the contacts have welded after the input circuit has
opened.
} Open circuit, short circuit or earth fault ( e.g. in the input circuit)
