Warning Messages

A warning message is caused by a non-critical fault. When this occurs, the unit will not shut down, but

the

MATE3 system display will show an event and a specific warning message. This 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.

NOTE: The Radian series has no external indicators and requires the MATE3 system display to identify

a 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 60.)
Warning screens can only display warnings; they cannot clear them. The way to correct the fault may

be obvious from the message.

Possible Remedy

AC Freq Too High

The AC source is above the upper acceptable
frequency limit and prevents connection.

Check the AC source. If it is a generator, reduce its
speed.

AC Freq Too Low

The AC source is below the lower acceptable

frequency limit and prevents connection.

Check the AC source. If it is a generator, increase

its speed.

Voltage Too High

The AC source is above the upper acceptable
voltage limit and prevents connection.

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.

Voltage Too Low

The AC source is below the lower acceptable

voltage limit and prevents connection.

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.

Input Amps > Max

AC loads are drawing more current from the AC

source than allowed by the input setting.

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.

Temp Sensor Bad

An internal inverter temperature sensor may be

malfunctioning. One of the three internal

sensor meters may give an unusual reading.

In the MATE3, the three readings are

labeled

Transformer, Output FETs, and

Capacitors. These values are given in degrees
Celsius. See next page.

Phase Loss

A slave 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.

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.
