XPR300 Instruction Manual 809480 311
CAN codes (500 – 503, 510 – 513 for gas connect console, 504 – 505, 514 – 515 for CAN cable and
jumper block, 507 – 508 for CAN network and bus, 600 – 602 for no CAN communication)
Multiple codes at the same time can indicate a problem with the CAN cable. If there is only one
code, the problem is more likely to be caused by what the code says (not the CAN cable).
1. Remove the power from the cutting system. Refer to Remove the power from the cutting system
on page 240.
2. For chopper-related codes, make sure that the chopper ID cable connector is fully engaged in
J8 on Chopper 1 and Chopper 2. If the chopper ID cable connection is good, continue with the
following steps:
a. For code 504 alone:
 Examine the CAN cable connection between Chopper 1 and Chopper 2. Look for loose
connections, bent pins, and bent sockets.
 Tighten loose connections if found.
 If you find bent sockets, order a new cable.
 If you find a bent pin, try to straighten it. If this does not work, order a new cable.
b. For code 503 and 504 together:
 Examine the CAN cable connection between Chopper 2 and the control board (PCB 1)
on the plasma power supply. Look for loose connections, bent pins, and bent sockets.
 Tighten loose connections if found.
 If you find bent sockets, order a new cable.
 If you find a bent pin, try to straighten it. If this does not work, order a new cable.
c. If the CAN cable connections are good, examine the PCB for Chopper 1/PCB 2 and
Chopper 2/PCB 3. Make sure that the following green LEDS are illuminated on each PCB:
 D22 (+18/-5 VDC)
 D14 (+5 VDC)
 D21 (+3.3 VDC)
WARNING
ELECTRIC SHOCK CAN KILL
Disconnect electrical power before doing troubleshooting or diagnostic work.
All work requiring removal of the plasma power supply outer cover or panels
must be done by a qualified technician.
See the Safety and Compliance Manual (80669C) for more safety
