What does it mean when I get an “428 generic alarm” at my ISX-GEN-ATS Smart Gen ATS panel?

 
 
Issue:
ISX-GEN-ATS - 428 generic alarm
 
Product line:
ISX-GEN-ATS – Cummins Diesel Generator
 
Environment:
All models, all serial numbers
 
 
Cause:
What does it mean when I get an “428 generic alarm” at my ISX-GEN-ATS Smart Gen ATS panel? 

This alarm means “water in the fuel” go to Generator for more detail.
 

Resolution:
The alarm that’s set at the APC-Schneider ATS panel display is a generic Generator alarm/ event, to obtain more description you must go to the Generator and check the alarms. Use Fault Acknowledge button to clear the alarm at the generator. After the alarm has cleared at the generator then check the ATS alarm is also cleared, if it is not cleared then toggle the automatic operation switch from auto to manual (reset) and back to auto to clear any latched alarms at the ATS panel.
 
Cummins FSR/ Generator repair tech should be called to look over the Genset fuel system and determine how to fix and clear the alarms. It’s possible you have water in the fuel/ water separator filter and that would need to be drained. Otherwise, some sort of sensing failure of this water in fuel sensing circuit. Call your Generator service company
