1. Verify that both 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 back side of J3.201, pins 2 and 10
on PCB3, is less than or equal to 2.9 VDC.
4. If the voltage is low, verify correct wiring between chopper
temp sensor and J3.201 pins 9 and 10.
5. If wiring is good and over temp error does not clear after 30
minutes, replace chopper.
6. If voltage is higher than 2.9 VDC and over temp LED does
not clear after 30 minutes, replace PCB3.
1. Verify that the large fan is 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 back side of J3.201 pins 2 and
8, is equal to or less than 3.2 VDC.
4. If voltage is low, inspect wiring between the transformer's
temp sensor and J3.201 pins 7 and 8. Look for shorts to wires
or ground.
5. If wiring is good, the transformer has overheated.
6. If voltage is higher than 3.2 V and over temp error does not
clear after 30 minutes, replace PCB3.
1. Verify that all four fans in the coolant heat exchanger are
running.
2. Blow dust out of the system, especially from the heat
exchanger.
3. Verify that the voltage on the back side of J3.201 pins 2 and
6, is equal to or lower than 2.8 VDC.
4. If voltage is low, inspect wiring between coolant sensor and
J3.201, pins 5 and 6, for shorts to wires or ground.
5. If wiring is good, the coolant has overheated; let system
stand for 30 minutes to cool.
6. If voltage is higher than 2.8 VDC and the over temp error
does not clear after 30 minutes, replace PCB3.
1. If this is a new system, follow start procedure.
2. Verify that the coolant filter is in good condition.
3. Perform coolant flow test procedure (
Maintenance
section).
4.Verify that the CNC drives the plasma start signal for at least
10 seconds to allow the timed-out pump to turn on again.
1. Verify that the temperature sensor for the chopper has not
been jumped out or the wires to the temp switch shorted out in
the harness.
2. If no jumper is present, the chopper is overheated and needs
time to cool to 83° C (181.4° F).

Chopper 2
over temp at
power-up
Dipswitch No.1 is not in
the correct position. It is in
the OFF position.
1. For 130 amp systems verify dipswitch No.1 is in the OFF
position.
2. For 260 amp systems repeat step 1 and 2 in error code 99.
