The trip lockout function is used to prevent accidental closing of the circuit breaker

after a trip. The trip lockout function must be locally reset with a separate reset

command before the circuit breaker can be closed again. This function is useful

when the trip output contact of the relay is latched or the open circuit of the circuit

breaker remains activated.

The trip lockout function is selected in SGF1. When selected, PO3 is dedicated to

this function. As long as no trip occurs, PO3 is closed.

Every signal which has been routed to PO3 via the output signal matrix activates the

trip lockout function and opens the contacts of PO3. When the contacts have

opened, they are locked into the open state.

The trip lockout function can also be activated externally, via a digital input. The

trip lockout function can be reset via a digital input, the HMI or SPA parameter

V103, but not before the signal which activated the function has been reset.
