feedback has exceeded
160 amps.
1. Verify that the wiring between CS3 and PCB3 is correct
and not damaged.
2. Measure voltage across current sensor.
a) Red to black = +15 VDC, Green to black = -15 VDC,
white to black = 0 VDC at idle and varies with current
output (4 VDC = 100 amps).
b) If possible, take a voltage reading on current sensor
while trying to cut. Ratio is 4 VDC = 100 amps.
c) If the current sensor voltage is approximately 6.4 VDC
or greater at idle, replace the current sensor.
3. Remove connector JC.1 from the chopper and verify that
LED1 is extinguished.
a) If LED1 is extinguished with the connector removed,
then reconnect JC.1 and try to fire the torch. If the
chopper still goes into overcurrent, replace the chopper.
b) If the chopper does not go into overcurrent, replace
PCB3..

1. Verify that the voltage at CS2 is correct.
2. Verify that the wiring between CS2 and PCB3 is correct
and not damaged.
3. Swap CS2 with CS3. If the error code changes to 157,
replace the original CS2.
