Troubleshooting
• Gen Type is 2-Wire Standby Mode – When using 2-Wire
Standby mode, the gen run sense signal is communicated from
the remote control to the AGS through the remote control cable.
The AGS determines that the generator is running when the
remote communicates that it is in a charge state (e.g., Charging,
Bulk Charge, Absorb Charge).
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
communications cable to the green NETWORK port on the AGS.
1. Ensure the remote control is in a charge state (e.g.,
Charging, Bulk Charge, Absorb Charge). If not, then:
a) Ensure generator’s AC output connected to inverter’s
AC input. Check wiring/AC breaker to inverter’s AC input.
b) Ensure the AC input breaker on the inverter has not
popped out/opened up.
2. Ensure the network (Section 2.4.2) and remote cables are
the correct type (see your remote’s operating manual).
• Gen Type is not 2-Wire Standby Mode – All gen types (except
2-Wire Standby mode) use DC voltage as the gen run sense
signal to the AGS. While the generator is running, use a DC
voltmeter to con
¿
rm there is 10 to 40 VDC between Terminals 2
(+) and 4 (–) on the AGS’s green 8-port terminal.
Note: These tests can be performed without either a remote control
connected to the inverter, or the network communications cable
connected from the inverter to the AGS’s green NETWORK port.
A) Use a DC voltmeter to ensure you have a 10-40 VDC reading
between Terminals 2 and 4 while the generator is running. Shut
the generator down, and then recheck voltage to con
¿
rm it has
gone away with the generator being off.
1. If the voltage is correct and goes away when the generator
is off, then the gen run sense signal is correct. Proceed to
the remote control section to set up and enable the AGS
to autostart your generator.
2. If the voltage is still present with the generator off, then
it is not a correct gen run sense signal. Determine where
it is coming from and remove or correct it using the gen
run sense signal (voltage) options found in Section 2.6.2.
B) If the DC voltage is incorrect or missing between Terminals
2 and 4:
1. Check the fuse and wiring to Terminal 2. The wire on
Terminal 2 may be loose, you may have a blown fuse,
or the other end of the wire may not be connected to a
proper run signal like the Gen Hour Meter or one of our
alternate gen run sense signal (voltage) options found in
Section 2.6.2.
