Troubleshooting Tips for Your Dust Collector’s Pulse Clean System

A functioning and efficient pulse clean system will extend filter life and minimize operating costs. Follow the tips below to troubleshoot electrical and pneumatic problems with your dust collector's pulse clean system to ensure that it operates effectively and efficiently.

Electrical Problems

• Make sure that the power light is glowing, which indicates that there is power to the timer control.

• Each solenoid has a terminal connected to the output channel on the timer board, and a terminal connected to the solenoid common terminal. If a pressure switch is connected to the timer board, confirm it's calling for cleaning. If no pressure switch is used, the p.s. terminals are jumpered together on the timer board.

• If the timer board is not sequencing, check the fuse.

• When the timer board is sequencing, an indicator light for each output channel will glow momentarily, as the channel is energized.

Pneumatic Problems

• Check the pressure in the air manifold. The air pressure should be 85-100 PSI, and the air should be clean and dry air with sufficient volume to maintain the pressure.

• Diaphragm valves are normally closed, but they open for a split second to allow a burst of compressed air to pulse the filter. If a diaphragm valve is stuck open, hold a finger over the small bleed port at the end of the electrical solenoid to check for leaks. If air is leaking from this port, the solenoid needs to be rebuilt or replaced. If there are no leaks from solenoid valve and tubing, depressurize the manifold and clean or replace the diaphragm and spring in the pulse valve.

• If the diaphragm valve will not open, confirm there are no kinks in the tubing and check that the electrical solenoid is operating.
