Maintenance and Repair
To make sure that the unit is adjusted correctly and not too sensitive, close
the door and manually run the mixer. The LED should not change states
while the mixer is running, which would indicate that the sensor is seeing the
mixer pass the face. If this occurs make sure that all pieces are installed cor-
rectly and adjusted flush with the mixing chamber. If the unit still sees the
mixer, adjust blade in front of sensor and re-calibrate so the blades are not
seen by the sensor.
9.6.1.1 Calibrate/adjust a sensor with material present

2
For most applications setting the sensor with the vessel empty is sufficient. You
can, if you wish, make additional adjustments with material present in the bin.
Making a full adjustment (material present) does not change the empty
adjustment. This type of adjustment may need to be completed for low bulk
density materials.
With material present, press and hold the pushbutton adjustment with a pen or a
small screwdriver for more than 5 seconds, but less than 10 seconds. For the first
5 seconds the green LED will flash slowly (approx. 1 Hz or 1 flash per second)
after approx 5 seconds then it will begin to flash faster (approx. 2 Hz or 2 flashes
per second). Release the pushbutton as soon as the green LED begins to flash
faster (approx. 2 Hz – or 2 flashes per second.
The yellow and green LED's will be lit – this means the unit is set and is in
operating mode.
