Warning Messages - Outback Power Systems FXR2012E Operator's Manual

Warning Messages

A warning message is caused by a non-critical fault. When this occurs, the ERROR indicator will flash,
although the inverter will not shut down. (See page 15 for the FXR inverter's LED indicators.) The
MATE3 system display will show an event and a specific warning message. The Inverter Warnings
screen is viewed using the MATE3 Home screen's soft keys. (See the MATE3 manual for more
instructions.) One or more messages will display Y (yes). If a message says N (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
page 65.)
Warning screens can only display warnings; they cannot clear them. The way to correct the fault may
be obvious from the message.
Message Definition
The AC source is above the upper acceptable
AC Freq Too High
frequency limit and prevents connection.
The AC source is below the lower acceptable
AC Freq Too Low
frequency limit and prevents connection.
The AC source is above the upper acceptable
Voltage Too High
voltage limit and prevents connection.
Voltage Too Low The AC source is below the lower acceptable
voltage limit and prevents connection.
Input Amps > Max AC loads are drawing more current from the
AC source than allowed by the input setting.
An internal inverter temperature sensor may
Temp Sensor Bad
be malfunctioning. One of the three internal
sensor meters may give an unusual reading.
Phase Loss A slave or subphase master inverter was
ordered to transfer to an AC source by the
master, but the AC source is the wrong phase
or no AC source is present.

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 acceptance
range is adjustable.
NOTE: Adjusting the range may accommodate a
problematic AC source, but it will not fix it.
Check the AC source. Check the AC wiring. The
inverter's acceptance range is adjustable.
NOTE: Adjusting the range may accommodate a
problematic AC source, but it will not fix it.
Check the loads. Oversized loads can open circuit
breakers. If they exceed the inverter's transfer
relay size, the relay can be damaged.
This issue is usually the result of a poorly-sized
load, as opposed to a wiring problem.
In the MATE3, the three readings are labeled
Transformer, Output FETs, and Capacitors.
These values are given in degrees Celsius. See
next page.
Check the AC voltage on the inverter input
terminals. If AC voltage is not present, problem is
external. If AC voltage is present, the unit may be
damaged. Contact OutBack Technical Support.
