inch of the sensor. It also connects to the K4 red connector
on the control board and has the same operating sequence
as the mechanicam bin control.
The capacitive proximity control has 4 components including
a sensor, bin control relay, 24VDC power supply and
resistor harness. This resistor harness is slightly different
from the harness used for the mechanical control. It will
supply either 15.8 K ohms or 5.6 K ohms to the red K4
connector to control the unit.
As the sensor switches, the resistance value will change
to either start up or shut down the unit through the control
board K4 connector.
a) When no ice is present within 1/2~1 inch of the sensor
end, the resistance at the K4 connector will be 5.6 K ohms
and the unit will start. This is the bin empty signal.
b) When ice is present within 1/2~1 inch of the sensor, the
resistance at the K4 connector will be 15.8 K ohms and the
unit will shut down within the first 5 minutes of the freeze
cycle. This is the bin full signal.
Note: Control board dip switch number 7 must be ON for
this control to operate the unit.
F/DCM Bin Control
Flaker / DCM units use a mechanical bin control. A paddle
pivots on a hinge pin to operate either a micro- switch or
magnetic proximity switch. For proper operation, make sure
that the paddle swings freely. The F-450MAF-C cubelet
unit uses an Infrared eye control since it is designed for
dispenser applications. This control has a seperate DC
power supply and an infrared sensor which is mounted
to the base of the ice chute.
CAPACITORS
See wiring diagram reference chart for capacitor ratings.
Check capacitors with an ohm meter for a short or open
circuit. A capacitor checker can be used to check the
capacitance however, it is a good common practice to
change a run capacator any time a PSC motor is replaced.
Always check the run capacitor if a PSC motor will not
start, is running slow, overamping, or overheating.
