Transformer
(in
Temps
screen)
Displays the ambient temperature around
the inverter’s transformer.
MATE3 system display only
: These values are given in
degrees Celsius.
MATE and MATE2 system display only
: Values are
given in a representative “digital count”. Lower
counts equal higher temperatures. Higher counts
equal lower temperatures. Room temperature is 210
to 220. The internal fan runs at 142 and stops at 164.
A count of either 0 or 255 is a defective sensor.
If any reading does not seem to reflect the inverter’s
temperature or conditions, contact OutBack
Technical Support.

Output FETs
(in
Temps
screen)
Displays the temperature of the FETs
(Field Effect Transistors) and heat sink.
Capacitors
(in
Temps
screen)
Displays the temperature of the inverter’s
ripple capacitors.
See page 47 for a table of temperature
operating points and effects.
Disconnect Messages
Disconnect messages explain why the inverter has disconnected from an AC source after previously being
connected. The unit returns to inverting mode if turned on.
The system display has a list of disconnect
messages. One or more messages will display
yes
in the MATE or MATE2. It will display
Y
in the MATE3
along with an event message. If a message says
no
or
N
, it is not the cause of the disconnection. See the
system display literature for more instructions.
The system display may generate a concurrent event and warning message following the disconnection.
(See page 41.) If the AC source is removed, the warning will be blank, but the cause of the last
disconnection will remain.
Disconnect messages only display the reason for the disconnection; they cannot correct it. It is usually the
result of external conditions, not an inverter fault. If the condition is corrected, the inverter will reconnect.
A few settings can be changed to accommodate problems with the AC source.

Possible
Remedy
Frequency Too High
The AC source has exceeded acceptable
frequency levels.
Check AC source. If it is a generator, reduce speed.
Frequency Too Low
The AC source has dropped below
acceptable frequency levels.
Check AC source. If it is a generator, increase speed.
Voltage > Maximum
The AC source has exceeded acceptable
voltage levels.
Check 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 < Minimum
The AC source has dropped below
acceptable voltage levels.
Check 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.
