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. Set value for thermal device in control panel not set.

1. Clog in cartridge filter (in conveying line filter case) and drying/regeneration filter.
If clogged, air will not circulate, potentially leading to overload of 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.
    [Point]
     
    1. Wear a mask when cleaning. Dust/particles will disperse in the air when blowing dry air.
    2. After cleaning, set filter in the original position and fasten securely.
