Electrical Tests

Electrical Tests

Electrical components inside the gun affect performance and safety. The following procedures test the condition of the power supply (18) and barrel (16), 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) with an applied voltage of 500 V. Connect the leads as shown.

Test Gun Resistance

1.Flush and dry the fluid passage.

2.Measure resistance between the electrode needle tip (9b) and the air swivel (35); it should be 156-180 megohms. See Fig. 5. If outside this range, go to the next test. If in range, refer to “Electrical Trouble- shooting”on page 24 for other possible causes of poor performance.

WARNING

Fire, Explosion, and Electric Shock Hazard

Megohmmeter Part No. 241079 (AA-see Fig. 5) is not approved for use in a hazard- ous area. To reduce the risk of sparking, do not use the megohmmeter to check electri- cal grounding unless:

9b

35

• 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.
