Electronic Control Board Function
An integrated circuit board and microprocessor are used to control the
electrical functions of the Raja beverage dispenser. Functional
features of the control board include:
• Ice bank control with compressor start-up protection
• Carbonator control with continuous run protection
• LED diagnostics
Inputs to the control board include line power, the ice bank position
sensor, and carbonator water level sensor. Switched outputs from the
circuit board include the compressor, agitator motor, condenser fan
motor, and carbonator pump (refer to electrical diagram in reference
section).
Ice Bank Control
The ice bank control operates the compressor and condenser fan motor
to control the size of the ice bank. The control board will not restart the
compressor until after the compressor has been off for at least 3 minutes
to allow the refrigeration system pressures to equalize.
