Electrical Tests
Electrical components inside the gun affect performance and safety. The following procedures test the condition of the power supply (18), barrel (16) and charging probe (31), and electrical continuity between components.
Use megohmmeter Part No. 241079 (AA) and an applied voltage of 500 V. Connect the leads as shown.
Electrical Tests
Test Gun Resistance
Measure resistance between the air swivel (35) and the charging probe socket (CC) (see FIG. 9); it should be
Fire, Explosion, and Electric Shock Hazard
Megohmmeter Part No. 241079
•The gun has been removed from the hazardous 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, explo- sion, and electric shock and result in serious injury and property damage.
Test Total Gun Resistance
Measure resistance between the charging probe tip
(BB)and the air swivel (35) (see FIG. 8.); it should be
