Error code
number
Name Description Corrective action
093
No coolant
flow
Coolant flow signal was
lost or never was satisfied.
1. If this is a new system, follow start procedure.
2. Verify that the coolant filter is in good condition.
3. Perform coolant flow tests (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.
095
High current
on CS4
A current greater than
35 amps has been
detected by
current sensor 4.
See the chopper test later in this section.
099
Chopper 1
overtemp at
power-up
Chopper 1 is indicating an
overtemp at power-up.
1. Verify that the temperature sensor for the chopper has not
been bypassed or that the wires to the temperature switch
are shorted out in the harness, or that the sensor is open.
2. If no jumper is present, the chopper is overheated and
needs time to cool to 83° C (181.4° F).
100
Chopper 2
overtemp at
power-up
Chopper 2 is indicating an
overtemp at power-up.
1. Verify that the temperature sensor for the chopper has not
been bypassed or that the wires to the temperature switch
are shorted out in the harness, or that the sensor is open.
2. If no jumper is present, the chopper is overheated and
needs time to cool to 83° C (181.4° F).
101
Magnetics
overtemp at
power-up
Main transformer is
indicating an overtemp at
power-up.
1. Verify that the transformer temperature sensor has not been
bypassed or the wires to the temperature sensor are not
shorted out in the harness.
2. Verify that the sensor is not open or shorted, if it is not open
or shorted, the main transformer is overheated and needs
time to cool to 150° C (302° F).
102
Chopper 1
current at
power-up
Chopper 1 current signal
is active at power-up
See wiring diagrams in section 7
1. Verify that the voltage at CS1 is correct.
2. Verify that the wiring between CS1 and PCB3 is correct
and not damaged.
3. Swap CS1 with CS2. If the error code changes to 156,
replace the original CS1.
103
High current
on CS1
A current greater than
35 Amps has been
detected by
current sensor 1.
See the chopper test later in this section.
104
High current
on CS2
A current greater than
35 amps has been
detected by
current sensor 2.
See the chopper test later in this section.
105
Low current
on CS1
A current less than
10 amps has been
detected by
current sensor 1.
See the chopper test later in this section.
