controls. Check incoming compressed air for proper pressure (90-110 PSIG [6.4-
7.2 BAR]), pulse flow (1.47 SCF standard cubic feet [41.6 liters] per pulse) and
pulse duraon (100 milli-seconds), correct any problems
Set points incorrect
Confirm all program inputs are suitable for the applicaon
Solenoid not firing properly
