Trip Circuit Supervision 74TC

2.12.2
The 7SC80 device features an integrated trip circuit supervision. 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 allocation of the required binary inputs does not match the selected supervision type, then a message to
this effect is generated (
Applications
•
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.
