10.2 Resetting the Bell Alarm with reclosing lockout (optional)
WL circuit breakers are normally configured to be immediately "Ready-to-close" again following a trip. With the automatic reset of the Bell
Alarm, the tripping coil is automatic resetting after the trip unit has tripped. The circuit breaker is immediately "Ready-to-close" again. For
confirmation, the tripped indicator must be reset, either manually on the trip unit or via the remote reset coil.
When the WL breaker is configured with option WLNOAUTRSET, the tripping coil must be manually reset before the circuit breaker is
capable of closing. The following instruction details the resetting of the Bell Alarm, and the tripping coil.
