Calibration
1. Remove the plastic cap in the rear of the sensing unit, exposing the potentiometer
adjusting screw, as shown in figure B1.
2. Turn the screw clockwise to increase sensitivity of cup detection, or counterclock-
wise to decrease sensitivity.
3. Calibrate the sensor:
CAUTION
Do not adjust sensitivity too far, or unreliable sensing could
result.
a. Using a piece of WHITE poster board or heavy cardboard, make a 5" x 5-5/8"
target.
NOTE
IT IS VERY IMPORTANT THAT THIS MATERIAL BE WHITE.
b. Place the target in the cup station just beyond the cup deflectors (see figure C-
2). The target should be standing vertically; not tilted forward or backward.
c. With the target in place, turn the adjusting screw clockwise very slowly until
the indicator just turns ON.
d. Turn the adjusting screw counterclockwise very slowly until the indicator just
turns OFF.
4. Replace the plastic cap.
5. Insert a mug into the cup station in the vending position and check to see that the
red indicator light is ON.
This calibration will be adequate for most cups or mugs. In some cases, a slightly more
sensitive setting is needed if the cup or mug is a dark color.
