Alarms 

Causes 

Voltage 

the pre-set over voltage threshold 

15 

R/L1 Phase Under 
Voltage 

Indicates that genset L1(R) Phase voltage has fallen 
below pre-set under voltage threshold. 

16 

Y/L2 Phase Under 
Voltage 

Indicates that genset L2(Y) Phase voltage has fallen 
below pre-set under voltage threshold 

17 

B / L3 Phase Under 
Voltage 

Indicates that genset L3(B) Phase voltage has fallen 
below pre-set under voltage threshold 

18 

Genset Phase 
Reversal 

Alternator phase sequence is not correct 

19 

Over Frequency 

Indicates that genset output frequency has exceeded the 
pre-set threshold 

20 

Under Frequency 

Indicates that genset output frequency has fallen below 
the pre-set threshold 

21 

Over Current 

Indicates that genset current has exceeded the pre-set 
shutdown threshold 

22 

Over Load 

Indicates that the measured kW load rating has exceeded 
the pre-set threshold 

23 

Unbalanced Load 

Load on any phase is greater or less than other phases by 
a threshold value 

24 

Over Speed 

Indicates that genset speed has exceeded the pre-set 
over speed threshold 

25

Indicates that genset speed has exceeded the pre-set 
gross over speed threshold 

26 

Under Speed 

The engine speed has fallen below the pre-set RPM 

27 

Extended Over Load 
Trip 

Indicates that there was 100% load on the genset for one 
hour in the time interval of last 12 hours 

28 

Battery Under Voltage 

The battery voltage has fallen below the pre-set threshold 

29 

Battery Over Voltage 

The battery voltage has exceeded the pre-set threshold 

30 

Maintenance Due 

Indicates that engine running hours has exceeded the pre-
set hours limit or maintenance due date has occurred, and 
filter servicing is required. 

31 

Mains Phase Reversal 

Indicates the Mains unhealthy condition 

32 

AVR Fault 

Generic fault 

33 

No speed signal 

If signal is not received when MPU speed signal source is 
selected in engine running condition. 

34 

Speed Sensor I/P Lost 

If engine speed sensing through sensor is enabled and 
GCU is not getting any signal from speed sensor. 

35 

High Voltage Failure 

If the voltage generated during the auto-exercise is too 
high 

36 

Low Voltage Warning 

If the voltage generated during the auto-exercise is too 
low 

37 

Alternator Input Lost 

If the alternator signal is lost 

38 

Low Voltage Failure 

If the voltage generated during the auto-exercise is too 
low  

39 

Auto Exercise Skipped 

If ambient temperature is less than 40°F and auto 
exercises time occurs, GCU skips exercise and gives this
