6.0 ME-AGS-N Module Troubleshooting
6.2 Generator Starting/Running Troubleshooting
This section helps troubleshoot the generator system when the AGSs STA-
TUS LED shows a fault condition (solid red LED indication), or the remote
control displays a generator autostart fault.
Press the
TEST
button on the AGS module, or start the generator from the
remote (refer to Section 8.2.1.2 - RC, 9.2.1.2 - ARC, and 10.2.1.3 - RTR).
6.2.1 If the Generator will not Start or Run
If the generator does not start after pressing the AGS modules
TEST
button,
follow the steps below.
1. Ensure the green READY indicator on the AGS module is on (blink-
ing or solid) to indicate that the AGS module is getting power
(see Figure 5-1).
2. Check the generator for fuel or for any fault codes, or check the gen-
erators operating manual for troubleshooting tips to resolve why the
generator will not start or run.
3. Check that the start/stop wiring has not come loose and is correctly con-
nected for your generator model. A wiring diagram for your particular
brand and model of generator may be available, check our website at:
http://www.magnumenergy.com/service/genwiringdiagrams.htm
4. Your generator may require a higher amperage start signal than what
our AGS relays are rated (approx. 5 amps); in that case, you will need
to supply a higher-rated external relay.
5. If the generator tries to start as soon as you initiate a test (instead of
waiting for the initial stop signal before attempting to start), check the
start and stop wire connections, it is possible that they are reversed.
6. Remove the generator start/stop wires from the AGSs 8-port terminal.
Simulate the AGS relays by physically connecting the start wires
rst to
ensure the generator starts and runs. Then, connect the stop wires and
ensure the generator stops. If the generator does not start or stop as it
should, recheck and troubleshoot the start/stop wiring to the generator.
6.2.2 STATUS LED does not go Solid
If the generator is running, but the STATUS LED on the AGS module is not
on solid, then:
1. Ensure the AGS is not in warm-up (STATUS LED should go solid once the
warm-up period is over).
2. Con
rm you are getting the correct gen run sense signal based on your
Gen Type setting.
Info:
Refer to the Gen Type Setting section (page 19) and Table 3-1
(page 20) to determine your Gen Type setting.
• Gen Type is 2-Wire Standby Mode
When using 2-Wire Standby
mode, the gen run sense signal is communicated from the remote con-
trol to the AGS thru the remote control cable. The AGS determines that
the generator is running when the remote communicates that it is in a
charge state (i.e., Charging, Bulk Charge, Absorb Charge, etc.).
Note:
In order to perform the 2-Wire Standby mode tests: the remote
control must be connected to the inverter, and the green Network port
on the inverter must be connected with the communication cable to the
green NETWORK port on the AGS.
