Error code troubleshooting (8 of 8)
Error code
number
Name Description Corrective action
134
Chopper
overcurrent
Chopper channel 1 current
feedback has exceeded
90 amps.
1. Verify that the wiring between CS1 and PCB4 is correct
and not damaged.
2. Measure voltage across the 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 the 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.
139
Purge
time-out
error
The purge cycle did not
complete within 3 minutes.
This is a warning for a possible gas restriction in the leads.
Verify that there are no restrictions in the plasma and shield
hoses.
151
Software
failure
The software has detected
an incorrect state or
condition.
1. Replace the power supply control board (PCB4).
152
Internal flash
error
Communication problem
to the flash chip on
the power supply control
board.
1. Replace the power supply control board (PCB4).
153
PS EEPROM
error
EEPROM memory on
power supply control
board is not working.
1. Replace the power supply control board (PCB4).
154
Chopper
overcurrent
Chopper channel 2 current
feedback has exceeded
90 amps.
1. Verify that the wiring between CS2 and PCB4 is correct
and not damaged.
2. Measure voltage across the 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 the 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.
157
Output
current at
power-up
Chopper current signal
from CS2 is active
(greater than 5 amps) at
power-up. 1. Verify proper electrical connections to chopper current
sensor (CS1) and to J4.2 on PCB4.
2. Verify proper electrical connections to chopper current
sensor (CS2) and to J4.2 on PCB4.
