Torque Control
Function/Operation
The thickness (and indirectly the temperature) of the
slush is controlled by a sensing device called the
Torque Switch. The refrigeration system is brought on
and off by a microswitch.
Inside the beater is a torque rotor to sense the
thickness of the product in the freezing cylinder. The
torque rotor should be inserted in the beater drive shaft
at the rear, and in the center of the door at the front.
When the beater turns, the moving product freezes
and exerts a clockwise pressure against the rotor as
the product thickens. This pressure is transmitted to a
torque arm, operating arm and spring.
When enough tension is produced, the microswitch is
tripped, breaking current to the holding coil of the
compressor; cycling the system off. As soon as the
compressor cycles off, the timer starts its 10 minute
timing period. When 10 minutes have elapsed, power
is sent through the timer to the solenoid. The solenoid
pulls the operating arm to the left, tripping the
microswitch. The microswitch sends power to the
holding coil of the compressor contactor; and the
system starts. When the product reaches serving
viscosity, the torque arm moves to the right, tripping
the microswitch, and the compressor stops. At this
time, the timer resets back to “0”.
When the draw handle is raised, the anticipator arm
assembly moves the torque arm to the left, tripping the
microswitch; starting the compressor.

Adjusting the Torque Switch
To achieve a thicker slush consistency, turn the
adjustment knob
clockwise
. This will increase the
spring tension, making it more difficult for the torque
arm to overcome the spring tension to trip the
microswitch.
To achieve a thinner slush consistency, turn the
adjustment knob
counter--clockwise
, to decrease
the spring tension.
