PFC2 Over Temp:
See PFC1 above for description.
AUX Over Current:
AUX stands for Auxiliary output. This alarm indicates that there
was a overcurrent condition on the AC AUX output. This could indicate that there is an
internal problem, which is drawing too much current. Another possible condition is that
the output load exceeds the maximum output rating, which caused the AUX output to
shut down.
MAIN Over Current:
MAIN stands for AC CURRENT MAIN output. This alarm
indicates that there was an over current condition on the CURRENT MAIN output. This
could indicate that there is an internal problem, which is drawing too much current.
Another more probable condition is that the output current exceeds the terminal
maximum output rating, which caused the CURRENT MAIN output to shut down.
Normally you will see this error message in conjunction with PFC1 Fail and PFC1 Fail.
This will happen when you are in the Momentary Mode and exceed the maximum
allowable overload for the Main output terminal. For example, you can normally get
about 13 Amperes from the 10 Amp output tap, when in the Momentary Mode. If you
exceed this value the unit will alarm off and you will see the following Alarm message;
PFC1 Fail
PFC2 Fail
MAIN Over Current
If you see this message, you will need to reset the unit by pressing the unit reset button
located just above the control knob, see Item #17 on Page 1 Unit Illustration. Then
move the test lead to the next higher output terminal and repeat your test.
AUX Over Temp:
This alarm indicates that there is an over temperature condition on
the AC AUX output. This could indicate that there is an internal problem, which is
causing an over temperature condition (fan not working). Another possible condition is
that the output duty cycle has exceeded the maximum ratings, which caused the AUX
output to shut down. In either case, allow the unit to cool down. Leave the unit on with
the fan running, and wait about 15 to 20 minutes before trying to operate again.
MAIN Over Temp:
This alarm indicates that there is an over temperature condition on
the AC CURRENT MAIN output. This could indicate that there is an internal problem,
which is causing an over temperature condition (fan not working). Another possible
condition is that the output duty cycle has exceeded the maximum ratings, which
caused the AC CURRENT MAIN output to shut down. In either case, allow the unit to
cool down. Leave the unit on with the fan running, and wait about 15 to 20 minutes
before trying to operate again.
DC_COMBO Over Current:
DC_COMBO stands for the DC AUX output. This alarm
indicates that there was a overcurrent condition on the DC AUX output. This could
indicate that there is an internal problem, which is drawing too much current. Another
possible condition is that the output load exceeds the maximum output rating, which
caused the DC AUX output to shut down.
