will initiate a warning alarm.
When the controller detects the imbalance current has exceeded the
pre-set value and the action selects "Warn" it will initiate a warning alarm.
When the controller does not detect synchronization signal within the
pre-set synchronization time, it will initiate a warning alarm.
When the controller detects fewer modules on the MSC link than the
