FUNCTION:
FORCING OUTPUT RELAYS
The output relays can be independently forced in static or dynamic mode. In static mode the selected relay will operate as long as it is
in the ENABLED state. Only when the user enters DISABLE, will the selected relay reset. In dynamic mode the user specifies the op-
erate time (1- 300 s) and the selected relay will operate for the specified duration.
The FORCE OUTPUT RELAY option is NOT allowed when the selected relay output is already active due to trip or alarm condition,
when the SR469 is in start block condition, or when the SR469 is not in service.
IMPORTANT NOTE:
•
THE FORCED RELAY WILL OVERRIDE ANY TRIP OR ALARM CONDITIONS.
(I.e. when the relay is forced and trip occurs, the relay will still be enabled when the trip condition is reset)
•
CONTROL POWER LOSS IN THE SR469 WILL
RESET
ALL FORCED RELAYS.
