Level Sensor Position Adjustment
Adjust the level sensor position by loosening the clamp screw with a hex
wrench and sliding the sensor up and down.
Hopper Level Sensor: Adjust the level sensor so that when the lance
proximity sensor stops the lance, the bottom of the level sensor is at the
position where you want the virgin transfer pump delay to start. This
position must take into account both the delay time and the usage rate,
since the powder level will continue to fall until the delay timer runs out and
the virgin pump is turned on.
Box Level Sensor: Adjust the level sensor so that the fluidizing bars and
lance are submerged in the powder when the level sensor contacts it. Each
time the powder level falls below the level sensor, the lance will be moved
down until the sensor is again in contact with the powder. The box proximity
sensor stops the lance before it contacts the bottom of the box.
