Table 8 Warning Alarms
When the controller detects that start battery voltage has exceeded the
pre-set value, it will initiate a warning alarm.
When the controller detects that start battery voltage has fallen below
the pre-set value, it will initiate a warning alarm.
When count down time is 0 and the action is selected "Warn", it will
initiate a warning alarm.
When digit input port is set as warning and the alarm is active, 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.
Least start genset number is not reached when start request delay is
over, it will initiate a warning alarm.
When current power percentage of bus is above 100% and alarm action
is selected to Warn, it will initiate a warning alarm.
When mains power is above pre-set output power limit and alarm action
is selected Warn, it will initiate a warning alarm.
When controller detects mains frequency is over pre-set limit, it initiates
a warning signal.
When controller detects mains frequency is below pre-set limit, it
initiates a warning signal.
When controller detects mains voltage is over pre-set limit, it initiates a
warning signal.
When controller detects mains voltage is below pre-set limit, it initiates a
warning signal.
When controller detects mains ROCOF is over pre-set limit, it initiates a
warning signal.
When controller detects mains vector change is over pre-set limit, it
initiates a warning signal.
