POSSIBLE OVERLOAD CONDITIONS DURING OPERATION
1. AVERAGE OVERLOAD
- Overload lamp turns on (continuous)
Cause:
Average power has exceeded programmed
limits.
Characteristics:
During operation “OUTPUT ON” indicator
will turn off and “OUTPUT OFF” indicator will
turn on. The output will be disabled. Operator
will observe decreased output voltage and
current. This condition will automatically reset
after three seconds. The three second time
out can not be bypassed.
Correction:
If average overload occurs repeatedly the
operator must reduce the output voltage and/
or one of the mode settings.
2. PEAK OVERLOAD
-
Overload lamp flashes -
(this condition
should not occur frequently).
Cause:
Likely shorted output, possible extreme load-
ing conditions.
Characteristics:
“OUTPUT ON” indicator will turn off and
“OUTPUT OFF” indicator will turn on. Output
will be disabled. VVP-15C will not reset after
three seconds.
Turn off control circuit (foot switch or anode
pole switch).
