not operating

Investigate

A, B, C, H, and L

D, E, F, G, J

D, E, F, and G, I, K

CHECK CONDITIONS SOLUTION

A. Power Supply No voltage or voltage incorrect Check incoming

voltage at outlet power supply

B. Stop/Start Switch No voltage through switch Replace switch

C. Vacuum motor No voltage at motor See A,B, & L

D. Filter Filter dirty Replace filter

(Also see G & J)

E. Air Ducts Obstructed Remove obstruction

F. Leaks in system Air leaking into system Replace gaskets &

repair leaks as necessary

G. Blowback air Low pressure Increase pressure

pressure incorrect (not to exceed 125 psi)

H. Limit switch No voltage through switch Replace switch

I. Load Time Chamber not filling sufficiently Increase load time

Chamber over-filling Decrease load time

J. Pulse rate Insufficient to clean filter Increase rate

K. Dump time Insufficient to allow complete Increase time

emptying of chamber

L. Pulse solenoid Correct voltage at solenoid Replace solenoid
