D. Initial Set up Conditions
This section is to help isolate the defective circuit before
troubleshooting, identify symptoms, and test the unit
for proper operation. Follow the instructions as given to
identify the possible symptom(s) and the defective circuit.
After repairs are complete, run the following tests again to
verify that the unit is fully operational.
1. Connect gas supply to rear of Power Supply.
2. Turn ON gas supply and set operating pressure per
pressure setting label on power supply.
3. Set the Power Supply controls as follows:
• ON/OFF SWITCH to OFF position
• Turn FUNCTION CONTROL SWITCH to SET position
• CURRENT CONTROL POTENTIOMETER to MAXI
-
MUM position, fully clockwise.
E. Main Input and Internal Power Test
1. Connect Primary Line power to the unit.
2. Turn the ON/OFF SWITCH (SW1) to ON position and
observe the following:
• Software version is displayed (See section 5.04
Fault Indicators)
After approximately three (3) seconds
• Inrush relay on PCB 1 energizes, starting pre-
charging of working capacitors.
• AC and GAS Indicators come ON
• Gas flows
• After 4 seconds W1 energizes
For earlier units, Fan MOT 1 turns ON for one (1)
second then shuts OFF.
3. Adjust the pressure regulator to set the gas pressure
as specified in charts.

4. Turn FUNCTION CONTROL SWITCH to RUN position
• Solenoid turns OFF, gas stops flowing (pressure
display may increase slightly when gas is not flow
-
ing)
This completes the Main Input and Internal Power Test. If the
above are all correct then proceed to the next section "F. Pilot
Arc Test". If the unit does not function as stated above, then
note the symptom and proceed to Section "5.07, Main Input
and Internal Power Problems".
F. Pilot Arc Test
There are three types of START signals which can be used to
begin system operation:
1. Hand Torch - Operator switch mounted on the torch
handle.
2. Machine torch or Automation torch:
A.
Hand held pendant switch
B.
CNC cable interfaced to controller.
1. Provide a START signal to establish a pilot arc and note
the following
• Cooling fans MOT 1-3 turn ON.
• Gas solenoid opens
• Gas flows
• After two seconds the gas solenoid closes and
gas stops flowing momentarily, then gas solenoid
re-opens and gas resumes flowing.
• DC LED comes ON
• Pilot arc is established
2. Remove the START signal and note the following
• Gas continues to flow
• DC LED goes OFF
After 20 second post flow time
• Gas solenoid closes
• Gas flow stops
