COMPONENT DESCRIPTION
E. ICE BIN LEVEL LIGHT CONTROL – BLACK
FOUR POLE CONNECTOR –AUTOMATIC
RESET
The electronic ice bin level control (located on the
ice spout) stops the operation of the ice machine
when the light beam between the light source and
the sensor gets interrupted by the ice which
accumulates in the spout.
When the light beam is interrupted for 6 seconds,
the 1st RED LED (on the front of the PC board)
goes off and the ice machine stops ice production
and turns on the 6
th
YELLOW LED to show that
there is a full storage bin.
The 6-second delay prevents interruption of
machine operation in the case of minimal breaks in
the light beam that can occur due to the ice
dropping through the ice spout blocking the sensor.
As soon as ice is scooped out of the bin, the light
beam resumes contact with the two infrared
sensors of ice level control. The RED LED lights
up and after 6 seconds the ice machine resume its
operation and the 6
th
YELLOW LED turns off.
F. ICE/WATER OPTICAL DISPENSING DEVICE -
BLUE FOUR-POLE CONNECTOR
Located on the front of the dispensing area it
consists of a combination of an infrared Transmitter
and Receiver.
When a glass or a carafe is placed in front of the
Infrared sources, the optical device transmits a
signal to the PC Board. This activates the
dispensing drive motor, which in turn, puts into
rotation a dispensing vane that pushes the ice
towards a rectangular opening located in the
bottom of the storage bin.
After the glass/carafe is removed or the dispensing
time has elapsed (5, 10 or 15 seconds according to
the setting) the infrared transmitter switches off the
dispensing drive motor.
