Patent Pending Smart Model 247937 Standard Model 247936 Table of Contents Warnings . 44 2 312900D Warnings Warnings The following warnings are for the setup, use, grounding, maintenance, and repair of this equipment. [. . . ] Do not install or repair this equipment unless you are trained and qualified. Problem Cause Solution Poor wrap. ES ON/OFF valve OFF (0). * Turn ON (I). Check air pressure to gun; minimum 40 psi (0. 28 MPa, 2. 8 bar) needed at gun for full voltage. See Check Electrical Grounding on page 15 and Test Total Gun Resistance on page 23. Clean workpiece hangers. (In general, a Pro Xs Waterborne gun Gun air pressure too low. will have less wrap than a Pro Xs solventborne gun. ) Atomizing air pressure too high. Workpiece not grounded. * ES indicator light is off when the gun is triggered. 22 312900D Electrical Tests 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. Connect the leads as shown. Test Gun Resistance Measure resistance between the air swivel (35) and the charging probe socket (CC) (see FIG. If in range, test the charging probe resistance. AA Fire, Explosion, and Electric Shock Hazard Megohmmeter Part No. To reduce the risk of sparking, do not use the megohmmeter to check electrical grounding unless: · 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, explosion, and electric shock and result in serious injury and property damage. 35 CC ti13731 FIG. Test Gun Resistance Test Charging Probe Resistance Measure resistance between the metal spring in the charging probe (DD) and the charging probe tip (BB) (see FIG. If in range, inspect the spring and barrel socket for possible causes of poor continuity. Reassemble the charging probe and retest the gun resistance. Test Total Gun Resistance Measure resistance between the charging probe tip (BB) and the air swivel (35) (see FIG. If in range, refer to Gun Repair on page 27 for other possible causes of poor performance. AA AA BB BB DD ti13732 FIG. Test Total Gun Resistance 312900D 23 Electrical Tests Test Power Supply Resistance 1. Measure resistance from the power supply's ground strips (EE) to the conductive contact in the center of the power supply seal (FF). Insert a conductive rod (GG) into the gun barrel (removed for the power supply test) and against the metal contact (HH) in the front of the barrel. Measure the resistance between the conductive rod (GG) and the charging probe socket (CC). If resistance is in range, reassemble the gun and test the gun resistance. If you still have problems, refer to Gun Repair on page 27 for other possible causes of poor performance, or contact your Graco distributor.
