Mechanical Components
When adjusting, fill a vacuum hopper to see if the switch detects
your material. The LED on the switch goes out when it detects
material.
For increased sensitivity, turn the potentiometer clockwise.
For decreased sensitivity, turn the potentiometer
counterclockwise.
3-33 Adjusting Sight Glass Proximity Sensor
Sensitivity
You can adjust the sensitivity of the material level proximity
sensor in the sight glass. The factory setting usually is correct for
most applications. The sensor is factory-installed to the frame;
however, you should install the sensor at the material level height
you want.
When adjusting, fill the glass and verify that the sensor detects
your material. The LED on the switch goes out when it detects
material.
For increased sensitivity, turn the potentiometer clockwise.
For decreased sensitivity, turn the potentiometer
counterclockwise.
