SECTION 510-TROUBLESHOOTING GUIDE

Symptom
End of cartridge service life
Cleaning mechanism not properly adjusted
Compressed air pressure too low
Pulsing valve failure
Controller timer failure
Moisture in collector
Inlet baffle plugging, causing high inlet
velocities
Heavier dust loading than design (scalping
of product)
Cause
Replace cartridges (service life is determined by the
application)
Consult Customer Service (1-800-479-6801)
Increase cleaning frequency
Pulse for longer duration
Perform off-line cleanings
Check performance of diaphragm and solenoids (repair)
Check performance of timer/controller (adjust or repair)
Check compressed air supply (90-105 psi)
Increase filter media area
Change filter media type
Install overbags to prevent blinding
Consult Customer Service (1-800-479-6801)
See sections following Low Pressure / Compressed Air
Increase pressure (85-105 psi)
Decrease duration and frequency of the pulse events
Check compressed air dryer and clean if necessary
Check for obstructions in piping
Consult Customer Service (1-800-479-6801)
Check wiring between controller and pilot valves
Check tubing between solenoid valves and diaphragms
Check diaphragms (replace or repair)
Check solenoid valves (replace or repair)
Consult Customer Service (1-800-479-6801)
See sections following Timer / Controller Failure
Verify controller is operational
Check for appropriate power connections
Check to see if timer is indexing to all contacts
Check output on all terminals
Check accuracy of magnehelic gauge (if applicable)
Consult Customer Service (1-800-479-6801)
See sections following Moisture in Collector
Check for leaks in collector or ductwork
Insulate collector
Purge system after shutdown
Preheat unit before operation
Check compressed air dryer (-85 degree dew point)
Locate collector indoors
Consult Customer Service (1-800-479-6801)
Check to find type of baffle (channels, abrasion resistant
plate, or none)
Remove plugged baffle
Replace baffle with the appropriate style for application
Reduce moisture in the collection system – see above
Consult Customer Service (1-800-479-6801)
Check designed airflow against actual airflow, adjust
accordingly
