Blower is overloaded and overload relay trips. (i.e. CP-2 trips)
  1. Clog in cartridge filter (in conveying line filter case) and drying/regenerate filter.
  2. Weld damage/wear on contact point of electromagnetic switch in control panel.
  3. Weld damage/wear on contact point of electromagnetic switch in control panel.

1. Clog in cartridge filter (in conveying line filter case) and drying/regenerate filter.
If clogged, air will not circulate, potentially leading to overload to blower.
  1. Check to see if each filter is clogged.
  2. If dirty or clogged, blow clean dry air into filter and remove the clinging particles.
