DESCRIPTION.
Rearm of the sealed relay and/or returning to
zero of the internal reclosure counters
Only on model RRM-C. Pressing sends
voltage to the relay, it is started with the
address no. 1 in the RS485 system.
Select the number of reclosures: 0, 1, 2, 4, 6,
8. Position zero cancels the motorised circuit
breaker reclosures
Select the time between reclosures in units of
minutes: 0.5, 1, 2, 3, 4, 5
Indicates that the relay is being supplied and
the overload/short circuit breaker protection
is not tripped. Green LED.
