6.0 ME-AGS-N Module Troubleshooting
6.1 Using the ME-AGS-N’s LED Indicators
The two LEDs on the front of the AGS controller indicate how the AGS is
operating and help you troubleshoot the AGS system. The STATUS LED is bi-
color (green or red) and indicates the AGS’s status. The READY LED is green,
and lights if the AGS has power and the remote temp sensor is connected.
The AGS controller performs a “self test” when power is
 rst applied. The
green READY LED lights up (solid) and the STATUS LED blinks green once. If
the self-test is successful, test the AGS system for proper operation by press-
ing and releasing the TEST button. The STATUS LED blinks green, and the
AGS should start the generator. Once the generator starts, the STATUS LED
lights solid green and the generator runs for approximately 30-60 seconds,
and then shuts off (will not try to restart within the next two minutes). If the
generator does not start and stop as expected, refer to Table 6-1 below to
help
 nd a solution.
WARNING:
Completely unplug the green 8-port terminal block from
the AGS module before performing maintenance on the electrical or
generator system to prevent harm to servicing personnel.
LED
Indication
Symptom Solution
STATUS is on red
= Gen fault 1. Gen won’t start; or
2. Gen won’t run. It
starts, but is stopped
by the AGS (B+ or gen
run sense voltage not
sensed to Terminal
#2).
Refer to Section 6.0 “ME-AGS-N Module
Troubleshooting” for assistance.
Unplug/remove and reconnect the green
8-port friction-  t terminal block to reset
the STATUS (fault) indicator.
STATUS is blinking
green = Gen start
initiated
Gen start initiated. No problem – normal operation.
STATUS is on solid
green = Gen run
Gen is running.
No problem – normal operation.
READY is off =
No power con-
nected to the AGS
module
DC voltage to Termi-
nals #3 (+) and #4
(-) on module miss-
ing or incorrect.
1. Check fuse, check DC wiring.
2. Check the DC voltage under the AGS
TECH menu.
READY is blinking
= The tempera-
ture sensor is not
detected
Note: Temp sen-
sor is not required
to be connected
unless the temp
autostart feature
is needed.
The temp sensor
is not sensed or
plugged into the
purple REMOTE port.
1. Check the temp sensor cable and its
connection to the purple REMOTE port, or
2. Check the temp sensor cable for any
damage.
3. Obtain another temp sensor cable.
4. Check the DC voltage under the AGS
TECH menu.
READY is on
(solid) = Power
and temp sensor
connected
The temp sensor
is connected to the
purple REMOTE port.
No problem – normal operation.
