Using an AGS Module: Troubleshooting

7.3 AGS Troubleshooting using the ME-ARC

This section assists you in using your ME-ARC remote to identify a fault and to resolve an abnor-

mal operational condition detected within your AGS system.

7.3.1 AGS Fault Message Screen

When an AGS fault is detected, the ME-ARC’s red FAULT LED comes on and the fault status is

displayed on the LCD screen. Figure 7-6 is an example of how AGS fault messages appear on the

ME-ARC remote. Use the remote’s LCD screen and the information in this section to identify and

correct the issue.

Note: The FAULT LED blinks and the fault alternates with the inverter/charger status.

7.3.2 Resolving AGS Operational Statuses

The following operational statuses can display on your ME-ARC, and some may indicate an ab-

normal condition. This section provides additional information and assistance to resolve these

statuses (if needed).

• AC In – This is a normal status when the input to the inverter/charger is connected to an AC

source such as utility/grid power, or to an alternate generator that may not be controlled by

the AGS.

Remedy: The AC In status prevents the AGS from autostarting. To enable the AGS to

autostart the generator, remove any AC power connected to the input of the inverter/

charger.

• No Comm – If an AGS is installed, use the information below to determine the remedy.

Remedy: If an AGS is installed, then follow these steps:

1. Ensure the green READY indicator on the AGS controller is on (blinking or solid) to

indicate that the AGS controller is getting power.

2. Ensure the communications cable is connected from the Network port on the Magnum

inverter to the NETWORK port on the ME-AGS-N.

3. Ensure you have the correct communications cable.
