7.0 Using an AGS Module
• 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.
Remedy: Confi rm that all the autostop parameters that are active
or enabled can be satisfi ed before the SETUP: 04F Max Gen Run
Time setting is reached.
• If using the SETUP: 04A Gen Run VDC menu's parameters:
– with a battery voltage setting to autostop, ensure the autos-
top voltage is less than the temperature-compensated absorb
charge voltage.
– with the "Float" setting to autostop, ensure the time that the
charger is in the Bulk Charge and Absorb Charge¹ stages is
shorter than the 04F Max Gen Run Time setting.
Refer to the SETUP: 04A Gen Run VDC section for additional
information on this setting.
• If using SETUP: 04B Gen Run Time, confi rm you have not set
the total run time (start time to the stop time) longer than the
SETUP: 04F Max Gen Run Time setting.
• If using SETUP: 04C Gen Run Amps, confi rm the inverter
load(s) that is used to determine the Stop Gen AC Amps set-
ting is not required to run longer than the SETUP: 04F Max Gen
Run Time setting.
• If using SETUP: 04D Gen Run SOC, confi rm that the METER:
04A BMK SOC reading is not "Think'n", but shows an actual
percentage reading on the display (i.e., 85%), and the Stop
Gen SOC setting can be satisfi ed before the SETUP: 04F Max
Gen Run Time setting is reached.
• If using SETUP: 04E Gen Run Temp, the temperature around
the remote temperature sensor has not reached the Gen Run
Temp setting. You need to either lower the Gen Run Temp Start
setting, determine how to cool the area (remote temp sensor
location) to below the Gen Run Temp Start setting before the
04F Max Gen Run Time setting is reached, or increase the Max
Gen Run Time setting.
Lastly, confi rm that your warm-up and/or cooldown time when add-
ed to your autostop condition does not exceed the SETUP: 04F Max
Gen Run Time setting.
Info: Beginning with Revision 5.2 of the ME-AGS-N, the Max Gen Run
Time setting can be defeated. In some cases, it may be appropriate
to set the Max Gen Run Time setting to OFF. However, this feature is
mainly provided as a safety feature to ensure the generator doesn't
run longer than the time it takes to reach the autostop conditions or
to expend the generator's fuel capacity, whichever occurs fi rst – take
this into consideration if this setting is defeated.
Note¹: Several conditions determine the length of time that the charger is in the
Absorb Charge stage. Ensure the SETUP: 03E Absorb Done (Time, Amps, or SOC)
setting—determines when the Absorb Charge stage is complete and enters the
Float stage—is taken into account when setting the 04F Max Gen Run Time setting.
