Using an AGS Module: Troubleshooting
7.3.3 Resolving AGS Faults using the ME-ARC
Should an AGS fault occur, use your ME-ARC remote and the information in this section to resolve
the issue.
• Fault Gen Run – The generator successfully started and ran for more than two minutes, but
the generator unexpectedly stopped before the active AGS autostop condition was fi nished.
Info: The AGS controller determines the generator is running by monitoring the gen
run sense voltage/signal. When this gen run sense voltage/signal is no longer available,
the AGS thinks the generator is off or has stopped.
Info: Fault Gen Run detection is not active if the generator is manually started.
Remedy: A) If the generator is still running: Confi rm you are getting the correct gen
run sense signal to the AGS controller. Refer to your ME-AGS-N owner’s manual.
B) If the generator is not running: Check the generator for fault codes and adequate
fuel. If neither is an issue, check the generator’s owner’s manual for troubleshooting
tips to determine why it may have shut down on its own.
For the faults listed below, refer to the Remedy immediately following.
• Fault Amp – The generator failed to autostart and run per the SETUP: 04C Gen Run Amps
menu’s start parameters.
• Fault Exercise – The generator failed to autostart and run per the SETUP: 04H Gen Exercise
menu’s start parameters.
• Fault SOC – The generator failed to autostart and run per the SETUP: 04D Gen Run SOC
menu’s start parameters.
• Fault Temp – The generator failed to autostart and run per the SETUP: 04E Gen Run Temp
menu’s start parameters.
• Fault Test – The generator failed to autostart and run after the red TEST button is pressed
on the AGS controller.
Note: The ME-ARC can be set to manually turn the generator on and off, which can be used
to test the generator wiring to the AGS.
• Fault Time – The generator failed to autostart and run per the SETUP: 04B Gen Run Time
menu’s start parameters.
• Fault Topoff – The generator failed to autostart and run per the SETUP: 04G Quiet Time
Topoff start parameters.
• Fault VDC – The generator failed to autostart and run per the SETUP: 04A Gen Run VDC
menu’s start parameters.
• Fault 100% SOC – The generator failed to autostart and run per the SETUP: 04K Gen 100%
SOC Start Days menu’s start parameters.
Remedy: One of the above fault messages may display on the ARC remote when:
A) The AGS attempts to start the generator four times, but the generator failed to
start and run per the specifi c autostart parameters; or,
B) The generator started, but did not provide the correct gen run sense signal to the
AGS controller. For any scenario above, refer to the Troubleshooting section in your
ME-AGS-N owner’s manual.
• Fault MaxRn – The generator has turned off because the gen run time—after autostarting—
has exceeded the SETUP: 04F Max Gen Run Time setting.
Info: The Max Gen Run Time menu uses the SETUP: 04B Gen Run Time display to
determine the generator’s run time. Cooldown and warm-up times are not included in
the Gen Run Time display.
