Ho
w the unit w
orks — 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 rest
arted 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 fr
ont 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, t
he 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.
