Fault
The engine runs, but the controller
shows genset to be OFF.
The controller shows incorrect PF value
or kW or load current.
The controller shows incorrect mains
voltage or incorrect main alternator
voltage.
The controller shows incorrect reading
for any of LOP, fuel level or temperature
sensors.
AUTO mode troubleshooting
Fault
The controller does not start the engine
when a remote start command is sent
from an external device.
Controller does not stop engine even
when a remote stop command is sent
from an external device.
While in Auto mode, the controller
sends a Start command even if the
mains is present.
E-governor troubleshooting
Fault
• The actuator chatters after the
engine is stopped.
• The controllers shows that the
genset is operating, when the
genset is not operating.
• The controller shows a Fail to stop
alarm when the genset is stopped.
• The controller does not maintain the
target RPM.
• The engine RPM is not stable.
• The controller cranks the engine,
but does not start the engine.

Action
• Check if the MPU signal (if used), and main alternator voltage signal (L1
phase) are received by the controller terminals.
• Check if the LOP and LLOP are working OK. Check the wiring to the
controller.
• Check wiring of the alternator phase voltage and the CT to the controller.
• Check the CT ratio (if kW or current reading is faulty).
• Check the wiring of the phase to the controller.
• If the problem is not resolved, replace the controller and try again.
• Check the respective sensor and its wiring.
• Go to the Configuration menu on the controller. Make sure the sensors are
calibrated correctly.
Action
• Check the wiring of the remote start signal to the controller's respective
digital input terminal.
• Go to the Configuration menu on the controller. Make sure the digital input for
the remote start is configured correctly.
• Check that the controller is in Auto mode.
• Make sure that the mains monitoring and site monitoring are not enabled.
• Check the wiring of the remote stop signal to the controller's digital input
terminal.
• Go to the Configuration menu. Make sure the digital input for the remote stop
is configured correctly.
• Check that the controller is in Auto mode.
• Check the wiring of the mains L1, L2 and L3 phase to the controller's input
terminal.
• Go to the Configuration menu on the controller. Make sure the mains
monitoring is configured correctly.
Action
• Go to the Configuration menu, and make sure the configuration for the LLOP
and LOP is correct. Make sure the wiring for the LLOP and LOP is correct.
• Make sure that the mains voltage wiring is not connected to the genset
voltage terminals on the controller.
• Make sure that the mechanical linkage assembly is correct.
• Go to the Configuration menu and make sure the configuration for the E-
governor is correct.
• Make sure that the PID control gains are configured correctly.
• Make sure that the actuator moves to the full throttle position when the
controller cranks the engine.
