2.22.2.2 Setting Notes
General The number of circuits to be supervised was set during the configuration in address
140 Trip Cir. Sup. (Section 2.1.1.3). If the trip circuit supervision is not used at
all, the setting Disabled must be applied there.
The trip circuit supervision can be switched ON or OFF in address 4001 FCT
TripSuperv.. The number of binary inputs that shall be used in each of the super-
vised circuits is set in address 4002 No. of BI. If the routing of the binary inputs
required for this does not comply with the selected supervision mode, an alarm is
given („TripC1 ProgFAIL ...“, with identification of the non-compliant circuit).
Supervision with
One Binary Input
The alarm for supervision with two binary inputs is always delayed by approx. 1 s to
2 s, whereas the delay time of the alarm for supervision with one binary input can be
set in address 4003 Alarm Delay. 1 s to 2 s are sufficient if only the 7SD5 device is
connected to the trip circuits as the trip circuit supervision does not operate during a
system fault. If, however, trip contacts from other devices are connected in parallel in
the trip circuit, the alarm must be delayed such that the longest trip command duration
can be reliably bridged.
