Circuit breaker / contactor control
Associated functions
Latching / acknowledgment
Description
The tripping outputs of all the protection functions and all the logic inputs may be
latched individually.
Logic outputs may not be latched. The logic outputs set up in pulse mode maintain
pulse-type operation, even when linked to latched data.
Latched data are saved in the event of a power failure.
All latched data may be acknowledged locally on the UMI, or remotely by means of
a logic input or via the communication link.
The "Latching / acknowledgment" function associated with the "Circuit breaker /
contactor control" function may be used to perform the ANSI 86 "lockout relay"
function.

TC/circuit breaker position discrepancy
Description
This function detects a discrepancy between the last remote control order received
and the actual position of the circuit breaker.
The information is accessible via remote indication TS42.
