This alarm will occur when the GCB feedback input does not match the
expected position given by the GCB Close/Open output. It stays active until
the mismatch between the output and feedback persists.
ï‚· If there was no command issued by the controller and the breaker
(feedback) changes suddenly the position itself, the alarm will be
issued immediately.
ï‚· The alarm will be also issued if the breaker does not respond to an
open or close command within 2 seconds. If synchronizing is
disabled (binary input ForwSyncDisabl is active) the maximum
allowed reaction time is increased to 5.
