Troubleshooting
How do you use differential pressure (DP) to tell whether your pulse cleaning is working?
With clean-on-demand control the DP should sawtooth within about a 1-inch water-column (~249 Pa) window between the high and low setpoints. If it can't pulse down to the low setpoint, or pulses constantly, the filters or the air supply are the problem.

Troubleshooting
How does over-pulsing affect pulse valves and filters, and how should the setpoints be tuned?
Every pulse flexes the filter media, so over-pulsing shortens bag life and wastes compressed air. Set realistic high/low DP limits so the collector spends most of its time between them instead of cycling constantly — and don't over-pulse to mask bad air or spent filters.

Troubleshooting
The pulse valves are firing but the differential pressure won't come down — what should I check?
Work along the cleaning chain: confirm each pulse valve truly snaps open, check that the air-receiver tank holds pressure through a cleaning cycle, inspect the blow pipe and nozzle alignment, review the controller's pulse on-time and interval, and confirm the supply air is clean, dry and at the valve's rated pressure. If the pulses are strong and the air is right but DP still won't recover, the filter bags are likely blinded — plan a bag change instead of just lowering the setpoint.

Troubleshooting
The pulse valves keep firing but the differential pressure won't drop — could the hopper be the cause?
Yes — a hopper that isn't emptied in time is a classic hidden cause. When dust bridges or piles up into the bag zone it is re-entrained and re-deposits on bags you just cleaned, so the DP controller keeps triggering the valves while DP still won't fall. The result is constant pulsing that wastes compressed air and adds diaphragm cycles without fixing anything. Before blaming the valves, check the hopper: confirm the discharge (rotary airlock, screw conveyor, or valve) is running, and clear any bridging or buildup.

Product Q&A
When should you choose the SXC-D32L (SK01-C8A9-D32L) offline pulse controller?
Choose the SXC-D32L when a compartmented baghouse needs more flexibility than a fixed channel split: its channels can be freely allocated between pulse valves and lift valves, and the built-in differential-pressure sensor lets it clean on demand and raise high/low ΔP alarms without any external instruments. All ranges and factory defaults are in the technical parameters table on this page.
