Troubleshooting

WARNING
CAUTION
Check the problem against the symptoms in the following troubleshooting guide. The remedy may be quite
simple. If the cause cannot be quickly located, shut off the input power, open up the unit, and perform simple
visual inspection of all the components and wiring. Check for secure terminal connections, loose or burned wir-
ing or components, bulged or leaking capacitors, or any other sign of damage or discoloration.
The cause of control malfunctions can be found by referring to the sequence of operations, electrical schematics
and checking the various components. A volt-ohmmeter will be necessary for some of these checks.

Troubleshooting Guide

When the input power is applied to m2 Smart Plasmarc system, pump motor should turn ON immediately, the
power light on the front panel will be ON and fault light will be OFF (if there are no errors/faults) indicating nor-
mal operation.
Check the following:
1. If pump motor doesn't turn ON, fuse(F3) might be bad or check for a bad connection to pump motor.
2. If POWER light doesn't turn ON or main contactor and main fan doesn't turn ON, then it could be
caused by blown fuses F1 or F2.
3. If the FAULT light is ON, then check the CNC/Process Controller display screen for the type of error
message from Plasma Console.
