Process Errors

ID Problem
1 The shield gas output flow is higher than expected. 1. Check that the correct consumables are installed in the torch.
2 The shield gas output flow is lower than expected.
3 The gas control is not properly communicating on
the CAN bus.
4 The plasma gas output pressure is higher than
expected.
5 The plasma gas output pressure is lower than
expected.
6 The current output of the Plasma Console is higher
than expected.
7 The current output of the Plasma Console is lower
than expected.
8 The arc was lost before plasma start signal was
removed.
9 Coolant flow is lower than 1.0 GPM.
A The Plasma Console has thrown an error.
B The control board is not properly communicating
on the CAN bus.
C The system failed to start.
D Coolant level is below the recommended level for
operation.
E The cycle start was present during boot up.
F The plasma gas pressure sensor was reading a
pressure when there was no command.
10 The shield gas pressure sensor was reading a flow
when there was no command.

Maintenance/troubleshooting
2. Check for a leak in the shield output gas line from the gas control.
3. Check the flow reading while the start signal is low. If there is more than XX CFH
(X.X CMH), replace the shield gas pressure sensor.
1. Check that the correct consumables are installed in the torch.
2. Check for a clog in the shield output gas line from the gas control.
3. Check that there is power to the pressure sensor.
4. Check for a loose or misplaced wire from the pressure sensor.
1. Check for all the switches on SW1 of the IC board are toward the display.
2. Check for SW1 on the control board in the Plasma Console is set to "Closed"
3. Check for the CAN cable is properly connected to the module.
4. Check for power to the module.
1. Check that the correct consumables are installed in the torch.
2. Check for a clog in the plasma output gas line from the gas control.
3. Check the pressure reading while the start signal is low. If there is more than X
PSI (X.X BAR), replace the plasma gas pressure sensor.
1. Check that the correct consumables are installed in the torch.
2. Check for a leak in the plasma output gas line from the gas control.
3. Check that there is power to the pressure sensor.
4. Check for a loose or misplaced wire from the pressure sensor.
1. Pierce height is too high during start.
2. No plate under torch during cutting.
3. Pierce time is too long.
1. Check the coolant level in the coolant tank.
2. Check for a clog in the filter.
3. Check for a clog in the flow sensor.
4. Check for a kink in the coolant lines.
5. Check for power to the flow sensor.
Check the CAN PS error code for more details.
1. Check for all the switches on SW1 of the IC board are toward the display.
2. Check for SW1 on the control board in the Plasma Console is set to "Closed"
3. Check for the CAN cable is properly connected to the control board.
4. Check for power to the control board.
1. Check that the torch is close enough to the work piece.
2. Check that the work piece and work leads from the Plasma Console are con-
nected electrically (< 10 Ohms).
1. Refill the coolant tank with coolant.
2. Replace the coolant level sensor.
1. Check the start signal to the interface control while the Plasma Console is off. If
there is voltage on the input, find and fix the wiring error.
2. Check the start signal to the interface control while the Plasma Console is on. If
there is voltage on the input while the output of the CNC is off, check the interface
control wiring for a short to the input.
3. Replace the interface control.
1. Check the input pressure to the plasma gas.
2. Check the wiring for the plasma gas pressure sensor.
3. Replace the plasma gas pressure sensor.
1. Check the input pressure to the shield gas.
2. Check the wiring for the shield gas pressure sensor.
3. Replace the shield gas pressure sensor.
