Circuit breaker / contactor control
Associated functions
Trip circuit supervision and open / closed
matching
Description
This supervision is designed for trip circuits:
b with shunt trip units
The function detects:
v circuit continuity
v loss of supply
v mismatching of position contacts.
The function inhibits closing of the breaking device.
b with undervoltage trip units
The function detects mismatching of position contacts, coil supervision being
unnecessary in this case.
The information is accessible in the matrix and via the remote indication TS43.
Block diagram (1)
Wiring for undervoltage trip unit. (1) With MES option.
The function is activated if inputs I11 and I12 are set respectively as circuit breaker "open
position" and circuit breaker "closed position".

Open and close order supervision
Description
Following a circuit breaker open or close order, the system checks whether, after a
200 ms time delay, the circuit breaker has actually changed status.
If the circuit breaker status does not match the last order sent, a "Control fault"
message and remote indication TS45 are generated.
