Operating and indicating diagram of a restart cycle:
Remote indication
The auxiliary contact is activated in event of blocking on a residual current fault,
during checking and time delay phases.
In order not to forget to activate the recloser, the auxiliary contact on the 4P REDs is
activated if the residual current device remains in the closed position for 15 minutes
and if the recloser is inhibited (sliding cover open, i.e. moved to the right).
The auxiliary contact on the 2P REDs can be configured for three options:
Mode 1 : 1 NO contact for an indicator light
b
Mode 2 : 1 NC contact for a telephone dialler
b
Mode 3 : 1 intermittent contact, F = 1 Hz for a bell
