Problem
Probable Cause
Remedy
Insufficient airflow
continued
Pulse cleaning not energized
Use a voltmeter to check the solenoid valve. Make sure
the solenoid valve exhaust port weather cap is removed.
Solenoid valve failure, constant air
leakage
Replace solenoid valve. Lock out all electrical power to
the collector and bleed the compressed air system before
removing the valve.
Solenoid valve failure, failure to
open
Check voltage output from Solid-State Timer. If output
voltage is present, replace the solenoid valve. Lock out all
electrical power to the collector and bleed the compressed
air system before removing the valve. Make sure the
solenoid valve exhaust port weather cap is removed.
Diaphragm valve failure
Replace the primary and secondary diaphragms and
springs. Note: To reassemble the smaller secondary
diaphragm, remove the solenoid valve and pipe fittings
and push down on the top of the diaphragm to hold it in
the closed position while tightening the retaining bolts.
Lock out all electrical power to the collector and bleed the
compressed air system before any component repair work
is completed.
Solid-State timer failure
Using a voltmeter, check supply voltage to the timer
board. Check and replace the fuse on the timer board if
necessary. If the fuse is good and input power is present
but output voltage to the solenoid is not, replace the timer
board. See Solid-State Timer Installation.
Solid-State timer out of adjustment See Solid-State Timer and Solid-State Timer Wiring
