Using an AGS Module: Troubleshooting

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 autostop voltage is less than the

temperature-compensated absorb charge voltage.

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 de-

termine the Stop Gen AC Amps setting 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: 05B Battery SOC read-

ing 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 tempera-

ture 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 added to your autostop

condition does not exceed the SETUP: 04F Max Gen Run Time setting.

Info: Beginning with Version 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: 03D 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.

7.3.4 How to Clear AGS Faults

Go to the CTRL: 03 Gen Control menu, and then select OFF.

Note: After the fault clears and the reason for the fault is determined, be sure to re-enable the

AGS to autostart. Go to the CTRL: 03 Gen Control menu and select AUTO. Refer to Figure 7-2.

Once the fault is cleared and the reason for the fault is determined, you should re-enable the AGS

to see if the fault returns, or test the AGS/generator system by performing the AGS functional

test for your remote (see Section 7.1.2).

7.3.5 How to Clear AGS Fault History

Go to the TECH: 04 Fault History menu, press the SELECT knob, and then turn the knob until the

04D Clear Faults screen appears.

At the 04D Clear Faults screen, press and hold the SELECT knob until the “5.0 to 0.0 second”

screen countdown is ﬁ nished and the screen displays “HISTORY CLEARED”.

CAUTION: Before using the Clear Faults feature, be sure you do not want the fault

history for any device (inverter, AGS, or PT controller). Once fault history data has been

cleared, it cannot be retrieved.
