Section 7 Maintenance and
Troubleshooting
WARNING: Only qualified maintenance personnel should perform
maintenance on the Spirit system. The system utilizes potentially fatal
A.C. and D.C. voltages. All maintenance should be performed with
safety in mind.
Use extreme caution when working near the power conversion module
(i.e., chopper). The large electrolytic capacitors store large amounts of
energy even after power has been removed from the system. Wait at
least five minutes after turning off power, and then use a voltmeter to
verify that the capacitors are fully discharged before touching the power
conversion module.
Capacitor failure can injure and/or cause property damage. If
troubleshooting requires the system to be powered with the enclosure
panels removed, remain clear of the capacitors. Failure of a capacitor
can result in a sudden release of stored energy causing rupture of the
capacitor case.
Routine Maintenance
Note: At minimum, these checks should be performed on a monthly
basis. In excessively dirty environments or in heavy usage situations,
the checks should be performed more frequently.
Power Supply
1. Remove the left, right, front, and rear panels of the power supply.
2. Using clean, dry, compressed air, blow out all accumulated dust inside
the power supply, including dust on p.c. boards and fans. Be sure to
blow out the fan and heat exchanger at the rear of the unit. In an
excessively dirty environment, blow out the unit on a weekly basis.
3. Verify that all torch lead and work ground connections are secure and
free from corrosion.
4. Verify that the primary three phase A.C. voltage connections are tight
5. Verify that all p.c. board connectors are installed securely.
6. Verify that the rear panel cable connectors are installed securely.
7. Verify that the automatic gas console connector is installed securely to
the plug on the bottom of the gas console.
8. Check the torch coolant filter/deionization cartridge at the rear of the
power supply and replace if dirty.
9. Flush the cooling system every six months and replace the coolant and
coolant filter/deionization cartridge.
