FAQ

For ignition failure, briefly: adjust spark gap to 3‑4 mm, sand probe to bare copper, set air damper to 30% then fine‑tune, and listen for valve click – if none, check coil voltage.

Clear exhaust pipe, check fan rotation (swap phases if reversed), blow through sampling hose with compressed air, replace worn door seals, and have an electrician fine‑tune the pressure switch threshold.

Keep batch ≤95% rated capacity, increase drum speed by 5‑8 rpm, center deflector when cold, close butterfly 5‑10%, and empty chaff collector every batch.

Power supply or fuse issues, over‑temperature protection triggering, firmware hanging, and excessive on‑the‑fly adjustments can all cause equipment malfunction. To address these, first check the socket and fuse; if over‑temp protection has tripped, allow the unit to cool for 30 minutes and then reset; if firmware appears hung, unplug the power for 1 minute to reboot; additionally, program process curves in advance to minimise real‑time tweaks during operation.
