Tweco 300 XT Auto-Cut 400V - Manual (Page 54)

AUTO-CUT 300 XT
�-� OPERATION Manual 0-5290
• Normally used with nitrogen.
• Provides very smooth cut surface.
• Reduces smoke and heat input to the workpiece.
• Effective up to 1/2 inch (12.7 mm) maximum material thickness.
• Tap water provides low operating expense.
4.05 Power Supply Status Codes
NOTE
See the Appendix for Advanced Troubleshooting
On start-up and during operation, the power supply control circuitry performs various tests. If the circuitry detects
a condition requiring operator attention, the status display on the front panel shows a 3 digit code preceded by
either letter “E” (currently active fault) or letter “L” (last or latched fault) meaning a fault occurred stopping the
process but is not currently active.
Some conditions can be active indefinitely, while others are momentary. The power supply latches momentary
conditions; some momentary conditions can shut down the system. The indicator may show multiple conditions
in sequence; it is important to recognize all possible conditions that may be displayed.
NOTE
500 codes are not used for this system
CCM Status Code
Group 1 Plasma Process
Code Message Remedy / Comments
101 Plasma Disabled
Plasma Enable Off ; External Disable activated or CCM TB1-1&2 jumper missing; 40 circuit
ribbon cable from Relay PCB to CCM disconnected or defective;
102 Pilot Ignition Failure
Pilot did not start within 15 seconds. Torch consumable parts worn? Ensure current control
setting matches consumables; Plasma pressure too high; Defective Arc Starter; Defective
Pilot PCB; defective Inverter section 1A.
103 Lost Pilot
Pilot went out while Start active. Torch consumable parts worn? Ensure current control set-
ting matches consumables; Plasma pressure too high;
104 Transfer Lost
Arc was transferred to work for more than 50 ms and then went out while Start still active. Arc
lost contact with work, run off edge, over hole, etc.; Standoff too high; Ensure current control
setting matches consumables; Wrong gas pressure
105 Not used Reserved for legacy product
106
Pilot Timeout, no
Transfer
Must transfer from Pilot to Cutting Arc in 0.085 seconds (SW8-1 OFF) or 3 sec. (SW8-1 ON).
Standoff too high or void in work under torch; Current Control setting too low for consumables
resulting in: Pilot current too low for consumables; Wrong gas pressure.
107 Not used Reserved for legacy product
108
Tip to Electrode
voltage fault.
Tip voltage too close to electrode voltage. Rear panel gas switch set to wrong gas; Torch con-
sumable parts worn out; Wrong consumables installed causing tip to electrode short; Plasma
pressure too low; Leak in Plasma hose to torch; Current Control set too high for consum-
ables; Defective Pilot PCB; Shorted torch body .
