Crane Merchandising Systems 678, 670 Appendix B. The Infrared Mug/Cup Sensor, Indicator light

HOT DRINK SETUP/PROGRAMMING GUIDE

APPENDIX B. THE INFRARED MUG/CUP SENSOR

The infrared mug/cup sensor can sense the presence of a mug or cup without using moving parts.

Indicator light

The sensor is equipped with an indicator light. This light will help you get the best results from the infrared mug/cup sensor.

Under these conditions:

·Machine door open

·Cup station in place

·No cup in the station

The indicator light should be off. If it is on, it is indicating improper cup station alignment or excessive sensor sensitivity.

Under these conditions:

·Machine door closed

·Cup station in place

·No cup in the station

Press any letter on the selection switch panel, for example, A. Only the letter A should be showing in the message display. If “A MUG” is displayed, it indicates one or more of the following:

·Improper cup station alignment

·Excessive sensitivity (the sensor is sensing the delivery door)

·Cup station lens is not clean

Cleaning

As indicated in the Sanitation section, you should remove the cup station to clean it. Pay particular attention to the dark colored infrared mug/cup sensor lens, which is part of the cup station. If it is not thoroughly cleaned, the sensor will not work properly.

CAUTION

Do not get liquid inside the sensor unit.

Cleaning the infrared mug/cup sensor unit itself is not usually necessary. If it does require cleaning, just wipe it with a damp cloth.
