Warning Messages; Table 6 Warning Troubleshooting - Outback Power Systems GFX1312E Operator's Manual

Warning Messages

A Warning message is caused by a non-critical fault. When this occurs, the unit will not shut down, but
the ERROR LED (see page 11) will flash to show a condition that requires attention. See the system
display manual for instructions on viewing warnings. One or more messages will display yes. If a
message says no, it is not the cause of the warning.
Some warnings can become Errors if left unattended. Frequency and voltage warnings are meant to
warn of a problematic AC source. Often the inverter will disconnect from the source. This will occur if
the condition lasts longer than the inverter's transfer delay settings. If the inverter disconnects, the
warning will display as long as the source is present, accompanied by a Disconnect message. (See
next page.)
Warning screens can only display warnings; they cannot clear them. The way to correct the fault may
be obvious from the message.
Message Definition
acin freq too high The AC source is above the upper acceptable
frequency limit (55 Hz) and prevents connection.
acin freq too low The AC source is below the lower acceptable
frequency limit (45 Hz) and prevents connection.
acin voltage too high The AC source is above the upper acceptable
voltage limit (252 Vac default setting) and prevents
connection.
The AC source is below the lower acceptable
acin voltage too low
voltage limit (208 Vac default setting) and prevents
connection.
AC loads are drawing more current from the AC
acin input current
source than allowed by the input setting.

Troubleshooting
Possible Remedy
Check the AC source. If it is a generator,
reduce its speed.
Check the AC source. If it is a generator,
increase its speed.
Check the AC source. The inverter's range is
adjustable. However, this will accommodate
an AC problem, not fix it.
Check the AC source. Check the AC wiring.
The inverter's acceptance range is
adjustable. However, this will accommodate
an AC problem, not fix it.
Check the loads. Oversized loads can trip the
input breaker. If they exceed the inverter's
transfer relay size, the relay can be damaged.
Check sensor readings (see below). The
numeric values represent electronic counts
between 0 and 255.1
Unit may require repair. Contact OutBack
Technical Support (see inside front cover of
this manual).
Turn the battery disconnect off, and then on,
to determine if the fan self-tests, then
contact OutBack Technical Support for the
next step. Meanwhile, run the inverter at
reasonable levels or apply external cooling.
Lower counts stand for higher temperatures,
and higher counts mean lower temperatures.
Room temperature is 210 – 220. The internal
fan runs at 142, and stops at 164. A count of
either 0 or 255 is a defective sensor. Contact
OutBack Technical Support if necessary (see
inside front cover of this manual).
