Maintenance/troubleshooting
Make sure the inputs are wired to the proper input on the IC.
Make sure the CNC is only sending the 24 VDC from DB37 connector
back to the IC as the input when turning the input on.
Check for voltage on the collector side. If there is a DC voltage there
greater than 10 volts, then call service.
Make sure the plasma gas box and shield gas box have power (green
LED on the same side as the cable connections is lit).
