MV2 error
Auto Gas
Only
Motor valve 2 did not
move into position within
60 seconds.
1. Verify that LED D19 or D20 is illuminating on the AC valve
driver PCB in the selection console. If either illuminates,
replace the motor valve. If they do not illuminate, replace
PCB3.
133
Unknown gas
console type
The power supply control
board does not recognize
the gas console that is
installed or has not
received a CAN message.
1. Verify that the part numbers of PCB2 and PCB3 are
correct.
2. Verify that cable number 5 (power supply-to-gas console
control cable) is not damaged and is properly connected to
PCB3 and the rear of the gas console.
3. Verify that cable number 6 (power supply-to-gas console
power cable) is not damaged and is properly connected
inside the power supply and to the rear of the gas console.
4. Verify that D1 (+5 VDC) and D2 (+3.3 VDC) are
illuminated on PCB2 inside the gas console. These LEDs
indicate power to PCB2.
5. If power is present at PCB2 and PCB3 and both gas
console cables are good, then PCB2 or PCB3 has failed.
Use the CAN tester to verify which board needs to be
replaced.
134
Chopper 1
overcurrent
Chopper 1 current
feedback has exceeded
160 amps.
1. Verify that the wiring between CS1 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 JA.1 from the chopper and verify that
LED1 is extinguished.
a) If LED1 is extinguished with the connector removed,
then reconnect JA.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.
