Torque Control
Operation
When the unit is placed in the “AUTO” mode, the
beater motor is activated. After a three second delay,
the compressor starts. When the torque sensor
indicates that viscosity has been achieved, it trips a
microswitch, and the compressor stops. The beater
motor continues to run for 20 seconds and then stops.
If the torque sensor returns to the unsatisfied position
during the additional 20 seconds of beater operation,
the compressor will run again for an additional 10
seconds (minimum), and will continue until the torque
sensor is satisfied. The beater motor will run for 20
seconds.
If the torque sensor remains in the satisfied position
after a 7 or 12 minute cycle time has elapsed, the
refrigeration system will reactivate for 12 seconds, or
until viscosity is satisfied.
