Smaller gap

The closer the arrow [] to SHUTTER DRUM, the bigger the gap. On the contrary, the fartherthe arrow [] from SHUTTER DRUM, the smaller the gap.

ActionMagnet●MOISUTURE SENSOR

SensorActionSHUTTER DRUM rotates180 degrees for 2 times to the same
direction (In total 360 degrees rotation). After that, rotating direction isswitched to opposite side and these actions are repeated.
SHUTTER DRUM stops at the time that the sensor detects themagnet. The standard distance that the sensor detects the magnet isabout 8mm.

Measuring roll
During the halt, the measuring rolls are thewaiting position. Switch A is close.

The measuring rolls move to sampling position
and wait for the coming sample for 90 seconds.
Switch B is close.

Crushing the sample, moisture value ismeasured. After measuring, the measuring rolls
return to the waiting position and the moisture

Troubleshooting for.L①The sample doesn't come into MOISTURE SENSOR.
→ Clean up the sample inlet and remove the foreign material in it .
