Siemens SIPROTEC 4 7VK61 - Setting Notes; Settings; Information List

The trip circuit supervision does not operate during system faults. A momentary closed tripping contact does
not lead to a fault indication. If, however, other trip relay contacts from different devices are connected in
parallel in the trip circuit, the fault indication must be delayed by Alarm Delay (see also Figure 2-62). After
clearance of the failure in the trip circuit, the fault message automatically resets with the same time delay.

Setting Notes
General
The number of circuits to be supervised was set during the configuration in address 140 Trip Cir. Sup.
(Section 2.1.1.2 Setting Notes). If the trip circuit supervision is not used at all, the setting Disabled must be
applied there.
The trip circuit supervision can be switched in address 4001 FCT TripSuperv. ON- or OFF. The number of
binary inputs that shall be used in each of the supervised circuits is set in address 4002 No. of BI. If the
routing of the required binary inputs does not comply with the selected monitoring mode, an alarm is issued
(
TripC 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. 1s to 2s, whereas the delay time
of the alarm for supervision with one binary input can be set in address 4003 Alarm Delay. If only the
device 7VK61 is connected to the trip circuits 1 s to 2 s are sufficient, 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.
