ELEVATION SERIES CIM CUBER CONTROL BOARD

Adjustment Switch Block
Three adjustments can be made on the block. Extended Purge, Bin Thermostat Kit add-on and
Cleaning Needed Reminder.
Standard Purge time during a Defrost Cycle is set at 7 seconds. To add an additional 5 seconds to
the purge time, move Switch 1 to the right, to the ON position.
Should the unit be installed on top of a dispenser, a Bin Thermostat Kit is required. Following the
instruction that come with the kit, Switch 2 needs to be moved to the ON position to tell the pro-
gram to read the Bin Thermostat. The LED beside the Bin Stat Connection will then illuminate.
The Switch 3 on the block is for the Cleaning Needed Reminder. When in the OFF position, the
default setting for the reminder is 6 months. When Switch 3 is moved to the ON position, the
Reminder is set for every 3 months. This is recommended should the unit be installed in a hard
water location to help with production levels.
12V DC Molex for Control Switches
This Molex connects the Magnetic Curtain Switch(es), High Float Switch, Low Float Switch and
Remote Configuration Switch to the Board. The LED’s associated to each switch will illuminate
when the contacts for each are closed. The Remote Configuration LED will be illuminated when
the Smart Harness reads the unit has a Remote Condenser. The Configuration 1 and both Fill Con-
figuration LED’s are not used as of the printing of this manual.
Thermistor Molex
The Thermistor is used to guage the water temperature in the Sump and is used to activate the
Anti-Slush Cycle. When the water temperature reaches 36 degrees F during the first 3 cycles fol-
lowing a full bin situation, being restarted after a loss of power or turned off, the Water Pump will
be turned off for 20 seconds to help prevent slushing of the water in the Sump. An Anti-Slush will
also be performed any time the water temperature reaches 28 degrees F.
Control Relays
The six Control Relays send voltage out to the individual components during the operation of the
unit. Relay 1 energizes the Fan(s) on self contained air cooled units or the Liquid Line Solenoid
on Remotes. Relay 2 energizes the Compressor through the Contactor (and Fan Motor on
Remotes). Relay 3 energizes the Hot Gas Valve and Harvest Assist Assembly during the Harvest
Cycle. Relay 4 energizes Water Inlet Valve. Relay 5 energizes the Purge Valve. Relay 6 energizes
the Water Pump.
Line Voltage Molex
The Line Voltage Molex connects for each component to the Board. See the wiring diagram for
each unit to see the wiring colors associated with each component.
Power and Clean Buttons
These buttons are functional duplicates of the buttons on the Push Pad mounted to the front frame
of the unit. See also “Button Function” chart in this manual for operation.
