3.2 PowerCut 1500 Indicator Lights (see figure above)
E. Power "ON" Indicator: Illuminates whenever the front panel power
switch is in the ON position.
F. AC Line Indicator or High/Low Line Voltage Indicator: This fault light
will blink to indicate that the input voltage is outside the "+ or -" 15% range
of the input rating.
G. Gas Flow Indicator: This fault light will blink to indicate that the air flow
supply is low or has no back pressure.
H. Fault Indicator: When this light blinks, either the system failed to initiate
a pilot arc after a number of attempts, or there has been an over-current
event within the system. If the light blinks for 10 seconds and then stops,
then the problem is pilot arc initiation. Check the consumables in the
torch.
If the light continues to blink, and the system does not reset, then the fault
is an over-current event. One likely source of an over-current fault is a
nozzle to electrode short. Turn off the machine and inspect the torch and
its consumables. Replace the consumables as needed. Turn the ma-
chine back on. If the problem occurs again, the machine may require
service.
I. Over Temperature Indicator: This fault light will blink to indicate that the
duty cycle has been exceeded. Allow the power source to cool down
before returning to operation.
All fault signals will remain on for a minimum of 10 seconds. If fault
clears, all will reset automatically except for over-current. To clear
over-current, the power must be shut off for 5 seconds and then
turned back on.
