Electrical Tests

Electrical components inside the gun affect performance and safety. The following procedures test the condition of the power supply (12) and barrel (6), and electrical continuity between components.

CAUTION

The barrel resistor cartridge is part of the barrel and is not replaceable. To avoid destroying the gun barrel, do not attempt to remove the barrel resistor.

Use megohmmeter Part No. 241079 (AA) and an applied voltage of 500 V. Connect the leads as shown.

Electrical Tests

Test Gun Resistance

1.Flush and dry the fluid passage.

2.Measure resistance between the electrode needle tip (40a) and the turbine air inlet fitting (TA); it should be 156-180 megohms. If outside this range, relieve pressure and remove the air cap (page 37). Inspect the electrode (40a) and the barrel conductive ring (6a) for damage and proper position, to ensure that the electrode makes contact with the conductive ring. Reinstall the air cap and repeat the measure- ment. If it is still outside this range, remove the gun for service.

WARNING

Fire, Explosion, and Electric Shock Hazard

Megohmmeter Part No. 241079 (AA-see FIG. 19.) is not approved for use in a haz- ardous area. To reduce the risk of sparking, do not use the megohmmeter to check elec- trical grounding unless:

•The gun has been removed from the haz- ardous area;

•Or all spraying devices in the hazardous area are turned off, ventilation fans in the hazardous area are operating, and there are no flammable vapors in the area (such as open solvent containers or fumes from spraying).

Failure to follow this warning could cause fire, explosion, and electric shock and result in serious injury and property damage.
