How the unit works — SensorSAFE model
SensorSAFE
™
models provide “touchless” ice and water dispensing. When a container is placed within the actuation zone below the ice or water chute, an invisible,
randomly-generated infrared signal is emitted, reflected off the container and detected by the sensor. The sensor then sends a signal to the control board to activate
the appropriate components to dispense ice or water. LEDs on the board indicate when the board is receiving a signal from the sensors.
A safety, shut-off feature automatically shuts off dispensing after one minute of continuous activation. Dispensing can be restarted by moving the container away and
then returning it to the actuation zone.
Dispensing can be temporarily suspended by depressing and releasing the clean switch, located under the left side of the top front cover. Depressing and releasing
the button a second time will return the dispenser to normal operating state. If the clean switch is not depressed a second time, the dispenser will automatically
resume normal dispense operation (CLN LED goes out) after two minutes. An LED on the control board will light to indicate that the dispensing has been suspended
by activation of the clean switch.
The bin signal circuit is completed through the normally closed contacts of the bin thermostat and the bin signal switch. When ice builds up around the bin
thermostat, the contacts open, cutting the bin signal.
