047
High line
voltage
Line voltage is close to or
greater than the upper limit
of 138 VAC
(120 VAC +15%).
The normal upper limit for
operation is 132 VAC
(120 VAC +10%).
1. Verify input–line voltage at PCB2 in the power supply and
PCB1 in the cooler (HPR400XD only). Voltage needs to be
within 10% of nominal (120 VAC).
2. Verify fuses on PCB2 in the power supply.
3. Verify 120 VAC voltage on plug J2.4, pins 3 and 4 on PCB2
in the power supply.
4. Verify the voltage on PCB1 in the cooler (HPR400XD
only) with a DC volt meter. It should be about 0.415 VDC
between TP23 and TP2 on PCB1.
5. If AC voltage on PCB2, J2.4, pins 3 and 4, is less than
132 VAC and DC voltage between TP23 and TP2 on PCB1
is greater than 0.44 VDC, verify maximum 132 VAC voltage
on plug J4, pins 1 and 2 on PCB1. Verify wiring between
PCB2 in the power supply and J4 on PCB1. If the voltage
on plug J4 is less than 132 VAC, but the DC voltage on
TP23 and TP2 is greater than 0.44, replace PCB1.
6. If the AC voltage on PCB2 in the power supply on plug
J2.4, pins 3 and 4, is less than 132 VAC and the DC voltage
between TP23 and TP2 on PCB1 in the cooler (HPR400XD
only) is also less than 0.44 VDC, verify the CAN link
between PCB3 in the power supply and PCB1 in the cooler.

Secondary
CAN error
An error occurred with
the CAN communications
between the power supply
and the gas console.
1. Verify that cable number 5 (power supply-to-gas console
control cable) is not damaged and is properly connected to
PCB3 and to the rear of the gas console.
2. 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.
3. Verify that D1 (+5 VDC) and D2 (+3.3 VDC) are illuminated
on PCB2 inside the gas console. These LEDs indicate
power to PCB2.
4. 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.

Secondary
Start signal
is on at
power-up
Plasma start signal input is
active during power-up of
power supply.
1. Stop or clear the cutting program. The plasma start signal to
the plasma was not dropped after the last cut.
2. Verify that the CNC interface cable is not damaged.
3. Remove CNC interface cable from PCB3 and look for an
open circuit between pins 15 and 34.
4. If the circuit is closed either the CNC is issuing a plasma
start or the CNC interface cable is damaged.
5. If circuit is open, and LEDN300J is illuminated with CNC
Interface cable removed from PCB3, replace PCB3.
053
Low shield
gas pressure
Shield pressure is below
lower limit of 0.14 bar
(2 psi).
1. Verify gas supply pressure and that a sufficient volume of
gas remains in your supply.
2. Verify gas regulator settings on gas console with cut chart.
3. See Setting the supply regulators (Installation section).
4. Perform gas leak tests (Maintenance section).
