No
Type
Description
1
Over Speed
When the controller detects that the engine speed has exceeded
the pre-set value, it will initiate a warning alarm.
2
Under Speed
When the controller detects that the engine speed has fallen
below the pre-set value, it will initiate a warning alarm.
3
Loss of Speed Signal
When the controller detects that the engine speed is 0 and the
action select “Warn”, it will initiate a warning alarm.
4
Gen Over Frequency
When the controller detects that the genset frequency has
exceeded the pre-set value, it will initiate a warning alarm.
5
Gen Under
Frequency
When the controller detects that the genset frequency has fallen
below the pre-set value, it will initiate a warning alarm.
6
Gen Over Voltage
When the controller detects that the generator voltage has
exceeded the pre-set value, the controller will initiate a warning
alarm.
7
Genset Under
Voltage
When the controller detects that the genset voltage has fallen
below the pre-set value, it will initiate a warning alarm.
8
Gen Over Current
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.
9
Fail To Stop
After “fail to stop” delay, if gen-set does not stop completely, it will
initiate a warning alarm.
10
Charge Alternator
Failure
When the controller detects that charger voltage has fallen below
the pre-set value, it will initiate a warning alarm.
11
Battery Under Volt
When the controller detects that start battery voltage has fallen
below the pre-set value, it will initiate a warning alarm.
12
Battery Over Volt
When the controller detects that start battery voltage has
exceeded the pre-set value, it will initiate a warning alarm.
13
Maintenance Due
When count down time is 0 and the action select “Warn”, it will
initiate a warning alarm.
14
Reverse Power
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.
15
Over Power
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.
16
ECU Warn
If an error message is received from ECU via J1939, it will initiate
a warning alarm.
17
Gen Loss of Phase
If loss of phase detection is enabled, When controller detects the
generator loss phase, it will initiate a warning alarm.
18
Gen Phase
Sequence Wrong
When the controller detects a phase rotation error, it will initiate a
warning alarm.
