4. The discharge valve is not functioning normally (close).
Check the condition of the discharge valve. If using while loading granulated materials, see if any particles or spool runners are trapped.
[Point] Use extra caution not to scratch the seal of the valve. [Point] If the spool runner is too long, grind twice.
Clean the valve if any materials are caught. Also, if materials are accumulating in the valve, adjust the secondary convey blow time or the secondary convey air. If the discharge valve (solenoid valve) is damaged, please repair or replace.
5. The delay time for full load in the secondary convey is not set at a sufficient time.
If the time settings for full load is long and causes too much material to be sent, it may lead to a decline in conveying abilities.
Display the secondary convey settings on the touch panel and check the settings.
Convey - Set the increasing time from the point where the conveying stops after the material in the receiving hopper exceeds full load (i.e. Demand Signal OFF) on secondary conveying.
Blow - Set the time for the completion of transfer of the remaining materials in the pipings after loading during timer setting time.
Input the setting time suitable for the quatity of the suction hopper.
