Genset has one red led. Led OFF means that the genset is not requested to start. Led blinking means
that the genset has been requested to start or the genset is running with an anomaly. Led ON indicates
that genset is running and ready to supply the load.
Genset contactor has one green led to show its status.
9.3 DETECTED AND SIGNALED FAULTS AND WARNINGS
9.3.1 WARNINGS
High Engine Temperature Warning occurs when the analog engine temperature sensor reading goes above
the High Engine Temperature Pre-alarm value set by HTP in the menu or when the engine temperature switch
is active and the 4 second fault delay is still being counted. The Engine Temperature symbol blinks indicating
this warning.
Low Coolant Level Warning occurs when the coolant switch is detected active and the 4 second delay is
being counted. The Coolant Level symbol (
) on the LCD blinks to indicate this warning.
Low Oil Pressure Warning occurs when the analog reading goes below the Low Oil Pressure Pre-alarm value
set by LoP in the menu or when the oil pressure switch is detected and the fault delay (2 sec) is being counted.
The Oil Pressure symbol blinks indicating this warning.
Low Fuel Level Warning occurs when the fuel switch is detected active and the 4 second delay is being
counted. The Fuel Level symbol (
) on the LCD blinks to indicate this warning.
Low Dynamo Voltage Warning occurs when the dynamo voltage decreases below the dynamo shutdown
voltage set by dSd and the 5 second delay is being counted. The Dynamo Voltage (
) symbol on the LCD
blinks to indicate this warning.
Over/Under Frequency Warning occurs when the frequency goes above/below the values set in GoF/GuF
(for Genset), UoF/UuF (for Utility) and the delay set by GoFd/GuFd (for Genset), UoFd/UuFd (for Utility) is
being counted. For the genset, the RPM symbol (
) turns on to indicate this warning.
Oil Change Warning occurs when the hours since last oil change exceed the value set by RHR. This warning
is indicated by the blinking of the Oil Pressure symbol on the LCD. To reset the oil change counter, press the
push button corresponding to the current operating mode for 2 seconds.
9.3.2 FAULTS
To delete the current fault, press and release the Off push button.
