Message Function description
Check the Fuel Level Sensor and associated wiring.
Speed Fault
The Speed Sensing system is not working as expected.
Check the associated speed sensor wiring and external influences such as
poorly operating battery chargers and poorly filtered UPS systems connect
to the load.
Speed Detected
Speed signal is unexpectedly present.
Check the associated speed sensor wiring and external influences such as
poorly operating battery chargers and poorly filtered UPS systems
connected to the load. Check electrical safety earthing systems. Check
associated communications networks are isolated and not part of an
unexpected earth loop.
Oil Detected
Oil Pressure is unexpectedly present.
Check the Oil Pressure Sensors and associated wiring.
Check the Oil filter system is not blocked.
Check the engine is not running with a failed speed sensing system.
E-S Lock-out
The emergency stop input has been activated. Deactivate the emergency
stop input, then press the stop button to clear this alarm.
Fire Alarm
The Fire Alarm input has been activated. The genset will be shutdown as
an emergency stop. Investigate the source of the alarm then press the
stop button to clear this alarm
A-S Lock-out
If the Stop button is pressed while running in auto mode, it is considered
an emergency stop and the unit will stop the engine and enter the
Autostart Lockout state. This prevents the engine from starting again,
while the Autostart input remains activated.
The Autostart Lockout state is self resetting upon deactivation of the
Autostart input.
If the engine was stopped for a real emergency, then the emergency stop
switch should also be activated to ensure the engine will not start
inadvertently.
If the unit is in the Autostart Lockout state, the engine can be restarted by
pressing the Start button. This is not considered a manual start but rather
a release from the Autostart Lockout condition. The contactors will be
controlled in the appropriate way.
AGF Phase Reversal The generator has a phase reversal or the wiring is incorrect

AGF High V2 Volts Voltage on Alternator Phase V2 is High
AGF High V3 Volts Voltage on Alternator Phase V3 is High
AGF High Frequency Alternator frequency is high
AGF Low Frequency Alternator frequency is low
