Position Position Sequence of Operations
Clean Serve -Drive Motor and Condenser Fan Motor start and run together,
or No time limit exists.
Standby -Power Transformer, torque switch, compressor, liquid level
control, and mix low light are non-operational.
On Serve -Drive Motor and Condenser Fan start and run together
continuously.
-Power Transformer is on.
-Liquid level control and mix low light are operational.
-With liquid mix or loose slush in the freezing cylinder, the torque
switch is closed. The delay-on-make timer starts the compressor
after a 10-30 second delay.
-When the slush reaches consistency, the torque switch opens
and the compressor immediately shuts off. The drive motor and
condenser fan motor continue to run.
On Standby -Power transformer, liquid level control and mix low light are
operational only when the temperature control is closed.
-Drive motor, condenser fan motor, and compressor cycle on and
off with the temperature control (compressor start delays 10-30
seconds).
NOTE
If the temperature control is set too cold, control will default to the torque switch to prevent freeeze-up.
