Trip circuit supervision
Functional Description
Trip Circuit Supervision
The 7VK61 incorporates an integrated trip circuit supervision function. Depending on the number of available
binary inputs (not connected to a common potential), supervision with one or two binary inputs can be
selected. If the routing of the required binary inputs does not comply with the selected supervision mode, an
alarm is issued (“TripC ProgFAIL”) with identification of the non-compliant circuit. When using two binary
inputs, malfunctions in the trip circuit can be detected under all circuit breaker conditions. When only one
binary input is used, malfunctions in the circuit breaker itself cannot be detected. If single-pole tripping is
possible, a separate trip circuit supervision can be implemented for each circuit breaker pole provided the
required binary inputs are available.
These which for the two binary inputs use binary inputs must have no common potential. Therefore, it must
be ensured the use of external measures for the galvanic separation.
Supervision with Two Binary Inputs
When using two binary inputs, these are connected according to Figure 2-59 parallel to the associated trip
contact on one side, and parallel to the circuit breaker auxiliary contacts on the other.
A precondition for the use of the trip circuit supervision is that the control voltage for the circuit breaker is
higher than the total of the minimum voltages drops at the two binary inputs (U
Ctrl
> 2·U
BImin
). Since at least 19
V are needed for each binary input, the supervision function can only be used with a system control voltage of
over 38 V.
