Other CB fail reasons:
 When the BO CB close/open is in steady state and CB feedback is changed, the CB fail is detected
immediately (no delay).

 When the BO CB close/open opens, there is 5 resp. 2 sec delay for the breaker to respond before a CB
fail is detected. In such case, if CB OFF coil is used for opening the CB and CB fail occurs during
opening the CB, the signal CB OFF coil is automatically extended until the breaker opening is detected
(evaluated as CB status).
 2 sec when the CB is used for synchronizing
 5 sec in other cases
