6.1 WARNING ALARMS
Warnings are not shutdown alarms and do not affect the operation of the gen-set. Warning alarms
does not lead to shutdown. Warning alarms types are as follows:
When the controller detects that the engine speed has exceeded
the pre-set value, it will initiate a warning alarm.
When the controller detects that the engine speed has fallen
below the pre-set value, it will initiate a warning alarm.
When the controller detects that the engine speed is 0 and the
action select “Warn”, it will initiate a warning alarm.
When the controller detects that the genset frequency has
exceeded the pre-set value, it will initiate a warning alarm.
When the controller detects that the genset frequency has fallen
below the pre-set value, it will initiate a warning alarm.
When the controller detects that the generator voltage has
exceeded the pre-set value, the controller will initiate a warning
alarm.
When the controller detects that the genset voltage has fallen
below the pre-set value, it will initiate a warning alarm.
When the controller detects that the genset current has exceeded
the pre-set value and the action select “Warn”, it will initiate a
warning alarm.
After “fail to stop” delay, if gen-set does not stop completely, it will
initiate a warning alarm.
Charge Alternator
Failure
When the controller detects that charger voltage has fallen below
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 the controller detects that start battery voltage has
exceeded the pre-set value, it will initiate a warning alarm.
When count down time is 0 and the action select “Warn”, it will
initiate a warning alarm.
If reverse power detection is enabled, when the controller detects
that the reverse power value (power is negative) has fallen below
the pre-set value and the action select “Warn”, it will initiate a
warning alarm.
If over power detection is enabled, when the controller detects that
the over power value (power is positive) has exceeded the pre-set
value and the action select “Warn”, it will initiate a warning alarm.
If an error message is received from ECU via J1939, it will initiate
a warning alarm.
If loss of phase detection is enabled, When controller detects the
generator loss phase, it will initiate a warning alarm.
When the controller detects a phase rotation error, it will initiate a
warning alarm.
