Inverter Troubleshooting
Symptom
Possible
Cause
LED Indicator
or Icon
Possible Remedy
Loads drop out
or crash during
transfer
Loads sensitive
to inverter’s
transfer time
N/A
The inverter features a small but noticeable response time
during transfer. Certain loads (such as highly sensitive
computers) may not respond well. An uninterruptible power
supply may be needed.
Loads too large
Red LED
Red
inverter icon
The unit can transfer more power than it can invert. If loads are
oversized, the unit will falter or crash when switching to batteries.
Reduce the size of the loads.
Undersized
battery cables
Red LED
Battery cables smaller than recommended will cause a
significant voltage drop when switching to batteries, acting like
either an overload or a low-battery condition. Size all cables
correctly.
Generator fails
to start; AGS
conditions
were met
Generator

set to
Auto
in
Action Menu
N/A
Both items must be set before AGS can function. In the
STATUS
view,
AGS Status
will not read
Enabled
if both items
are not set.
AGS

Enable
under
Generator
tab
Generator,
external fan,
etc. fails to
start when
signal is
provided by
A
UX
output
A

not connected
Yellow LED

Test the generator or device to confirm functionality. Test the
appropriate
A
UX
terminals with a DVM. (If the
R
ELAY
A
UX
terminals are in use, test for continuity. If the
12V
A
UX
terminals
are in use, test for 12 Vdc.)
If the proper results are present when the
Action Menu
indicates
the function is
On
(and the device still does not work), then there is
an external connection problem.
If the proper results are not present with the function
On
, the
A
UX
circuit may be damaged.
Wrong
A
UX
terminals were
programmed
Yellow LED
Yellow

Confirm that the
A
UX
item that was programmed matches the
terminals that are in use.

If generator or external device requires 12 Vdc, confirm the
12V
A
UX
terminals have been connected. The
R
ELAY
A
UX
terminals
do not provide voltage.
