No shield gas
type
Manual gas - The gas
console control board is
not receiving signals from
the gas selector knob.
Auto gas - The selection
console is not receiving the
plasma gas type signal.
1. Auto gas - the process parameters may not have been
downloaded. Verify that the process information can be
viewed on the CNC screen.
2. Manual gas - the selector knob (2) may be set between
positions. Reset the knob.
3. Verify that there is power to the console by looking to see if
any LED on any board in the selection console (auto) or
gas console (manual) is illuminated. If no LEDs are
illuminated, verify that the fuse on the power distribution
PCB is in proper working condition.
4. If the problem still exists, replace the control board.
065
Chopper 1
overtemp
Chopper 1 has overheated.
1. Verify that all chopper fans are operating properly. Spinning
fan blades should be difficult to see.
2. Blow dust out of system, especially from fans and heat sink
of chopper.
3. Verify that the voltage on rear side of J3.202, pins 2 and 3
on PCB3, is less than or equal to 2.9 VDC.
4. If the voltage is low, verify correct wiring between chopper
temperature sensor and J3.202 pins 1 and 2.
5. If wiring is good and overtemp error does not clear after
30 minutes of the power supply idling with the fans
running, replace the chopper.
066
Chopper 2
overtemp
Chopper 2 has overheated.
1. Verify that all chopper fans are operating properly. Spinning
fan blades should be difficult to see.
2. Blow dust out of system, especially from fans and heat sink
of chopper.
3. Verify that the voltage on rear side of J3.202, pins 5 and 6
on PCB3, is less than or equal to 2.9 VDC.
4. If the voltage is low, verify correct wiring between chopper
temperature sensor and J3.202 pins 4 and 5.
5. If wiring is good and overtemp error does not clear after
30 minutes of the power supply idling with the fans
running, replace the chopper.
067
Magnetics
overtemp
Power transformer has
overheated.
1. Verify that all the large fans are operating properly.
Spinning fan blades should be difficult to see.
2. Blow dust out of system especially from fans and large
power transformer.
3. Verify that the voltage on the rear side of J3.202
pins 14 and 15, is equal to or less than 3.2 VDC.
4. If voltage is low or near 0 VDC, inspect wiring between the
transformer's temperature sensor and J3.202 pins 13 and
14. Look for shorts between wires or to ground.
5. If wiring is good, the transformer has overheated. Allow the
power supply to idle with the fans running for a minimum of
30 minutes to cool the large power transformer.
6. Replace the transformer's temperature sensor if it is open
or shorted. Replacement kit part number is 228309.
