>4 After 3 consecutive occurrences of fault 4 the
machine will attempt to remove any blockages by
defrosting and cycling water – LED40 will be flashing
(5Hz) during this defrost and water cycle-defrost will
last for 5 minutes –Water will cycle for 10 minutes –if
the machine has 3 more consecutive short freeze
cycles, LED 40 will be solid and the machine will shut
down.
>6
Water fill exceeds 3 minutes then the Valve
closes & waits 10 minutes, as LED 60 Flashes. Valve
then opens & tries again. This routine repeats 3X and
results in a solid Code 6, if the fill is not completed on
the third try.
>7 Both Arm-Up/Arm Down (Cam ) Switches
Closed (un-actuated ) at the same time (not allowed ).
>8
Indicates that the machine is in full rinse mode
(left jumper pulled)
>9
Indicates bin full, Ice machine will be shut
down after current batch is complete.
Note: The controller will need to be reset to clear
these error codes. Board Revision numbers are
found on the sticker placed on a processor chip in the
middle of the control board. Example: 2.0
Stacked Jumpers:
• Under normal operation all machines will have a
jumper on the pins marked full rinse. If this jumper
is removed the water valve will stay energized to
thoroughly rinse the water plate during the water
plate lowering, harvest and water plate rising
cycles.
Note: The machine will need reset for the controller to
acknowledge this change.
• The right jumper is used to tell the controller when
it is being used on a dual evaporator machine.
BCO530 should not have jumper on.
Note: if you are replacing control board the new board
will come with jumper on. (MUST BE REMOVED OR
PLATE WILL NOT RISE).
Programming Port:
Used by service technicians to
alter or update the controller software.
Water Level Sensor:
Port for water level FLOATS.
Evaporator Temperature Adjustment:
To increase
the temperature of the evaporator at which the water
plate closes, turn this dial counterclockwise. To
decrease, turn the dial clockwise. The operator can

35 and 60F.
Note: After adjustment the controller must be reset.
Reset Button:
Reboots the controller.
Temperature Sensor Port:
For evaporator and bin
temperature sensor probes.
Bin Full Adjustment:
To increase the temperature at
which the ice level probe reacts to contact with ice in
the bin turn the dial clockwise. To decrease, turn the
dial counterclockwise. The temperature range for this
adjustment is between 33 and 45F.
Note: After adjustment the controller must be reset.
Switch Input Port:
For the on/off, ice/clean and limit
switches
Factory Use Only:
