General Troubleshooting
The following chart lists general troubleshooting guidelines for the ProLine system when
the status LED’s or the error LED do not give any insight to the particular problem being
experienced. Please contact KALIBURN technical support for any issues not covered in
this section. Before any tests are performed, make sure that all system fuses are good.
The primary system fuse F1 is located on the rear panel of the unit. All of the control
fuses are located behind the front panel of the unit beside the microprocessor p.c. board.
The automatic gas console fuse is located behind the right side panel of the system. Also
check all of the voltage LED’s on the system p.c. boards before performing any tests.
Problem
Possible Cause
Front panel white A.C. power light will
not illuminate
1. Primary disconnect fuse blown.
2. Fuse F1 or F4 blown.
3. White light or associated wiring bad.
4. Transformer TR2 or associated wiring bad.
Unit will not energize when the ON
button is pressed
1. RHF door open.
2. Low coolant level.
3. Fuse F4 blown.
4. Faulty ON switch or associated wiring. The
ON switch is normally open.
5. Faulty OFF switch or associated wiring. The
OFF switch is normally closed.
6. Relay CR1 coil open.
Power supply will not stay on when the
front panel ON button is pressed and
released
1. Check the control panel status LED’s and
troubleshoot accordingly.
2. Faulty latch relay on relay p.c. board.
3. Faulty relay p.c. board.
4. Faulty microprocessor p.c. board.
5. Relay CR1 defective.
No arc at the torch
1. Incorrect torch consumables installed.
2. Incorrect gas pressure settings.
3. Check the control panel status LED’s and
troubleshoot accordingly.
4. Check the spark gap assembly inside the RHF
console for proper arcing after a start signal is
applied. Open the RHF door and pull up on
the door interlock switch plunger to defeat the
interlock. If there is no spark, skip to the next
test.
5. Pilot arc resistor PAR or pilot arc transistor
PAT is not closing properly. Check the relay
for proper operation. Also, check the PAR and
PAT LED’s on the microprocessor p.c. board
and PAT drive p.c. board.
