Problem
Probable Cause
Remedy
Insufficient airflow
continued
Lack of compressed air
See the Specification Control Drawing shipped with the
collector for compressed air supply requirements.
Verify operation of PD pump.
Pulse cleaning not energized
Use a voltmeter to check the solenoid on the diaphragm
and the output of the PLC. Check for an orifice plug on
the solenoid valve and remove if present.
Dust storage area overfilled or
plugged
Clean out dust storage area. See Dust Disposal.
Pulse valve leaking air
Lock out all electrical power to the collector and bleed the
compressed air supply. Check for debris, valve wear, or
diaphragm failure by removing the diaphragm cover on
the pulse valves. Check for solenoid leaks or damage. If
pulse valves or solenoid valves are damaged, replace.
Pulse PLC failure
Using a voltmeter, check the PLC supply voltage. Correct
any power supply issues found. If the proper power is
supplied, and the pulse should be active, and still no
signal output to the solenoid is present, replace the pulse
controller.
Pulse Logic sensors out of
adjustment
See Pulse Alignment instructions in the installation section
in Appendix A.
Cleaning arm failure
Check for adequate clearance between nozzles and
tubesheet for free rotation. Check drive chain for proper
tension.
Low pressure system pressure
Check gauge at PD pump for proper pressure, 7.5PSI. If
pressure does not reach 7.5PSI before pulsing (expect
1 low pressure pulse every minute), check the PD pump
filter, Pressure Relief Valve, or if applicable compressed
air supply setting.
PD pump filter
Check for dirty filter. Clean and oil per manufacturer
recommendations if needed.
Pressure reflief valve
Check operation and verify that it is not discharging air
during normal operation.
Compressed air supply
Check settings and verify tank pressure reaches 7.5PSI
before pulsing.
