3) Beater Motor Overload Protector - Monitors the
current draw of the beater drive motor. If the motor
draws excessive amperage, the overload will trip and
Alarm 1 (RtA) will be displayed on the touch pad mo-
nitor.
4) Main Transformer – This transformer reduces the
incoming line voltage to 24 volts for the primary
control circuit.
5) Electronic Control Board – This board controls and
monitors
ALL
functions of the machine.
6) Current Monitoring Transformer –
This
transformer monitor the current draw of the beater
drive motor.
7) Secondary Transformer – This transformer reduces
the voltage from 24 volts to 11 volts for the electronic
control circuit.
F) Other Controls
1) Refrigeration Solenoid Valves – These valves are
located behind the front panel. These valves are used
to control the flow of refrigerant to the cylinders or
mix storage tanks. These valves are designated with
EVC for each cylinder and EVV for the mix storage
tank. (Refer to Figure 8)

2) High Pressure Safety Switch – In the event of
restricted airflow (Air Cooled) or restricted water flow
(Water Cooled), this switch will turn off the
compressor contactor. While tripped, the beater motors
will continue to run until the refrigerant pressure is
reduced enough to reset the safety switch. After
resetting, both the compressor and motor will resume
operation.
