Beater Stir Cycles
Standby
When the unit is in the STANDBY mode, the stir
cycle will be activated. The beater stir cycle timer
counts down two minutes (in seconds) and then
activates the beater motor for six seconds. After the
stir cycle, the process will repeat itself; the timer will
count down two minutes, and the beater will run for
six seconds.
Hopper T emperature
The hopper temperature setpoint range is 37 - 39°F
(2.8 - 3.9°C). In the AUTO or STANDBY mode the
compressor starts when the hopper temperature is
above the setpoint and stops when the hopper
temperature reaches the setpoint -2°.
The hopper liquid solenoid opens when the hopper
temperature rises above this setpoint and closes
when the hopper temperature is below its
setpoint -2°.
Setting Viscosity
Viscosity
Viscosity is the term used when referring to product
appearance, temperature, thickness and firmness.
Soft serve viscosity is measured by monitoring the
amperage load of the beater motor. The amperage
load of the beater motor is low when the product in
the freezing cylinder is liquid. As the product freezes
(thickens), the amperage load increases. When the
amperage load reaches the setpoint, the
refrigeration cycle discontinues.
The factory setting (setpoint) for soft serve viscosity
is 2.8 amps. The amperage measurement is
determined by monitoring the L1 leg of power being
delivered to the beater motor. To adjust the serving
viscosity, it may be necessary to raise or lower the
amperage setpoint. Adjust in increases of 0.1 amps.
The serving temperature of soft serve product may
vary throughout the day. The serving temperature
may range from 16_Fto19_F(-8.8_Cto-7.2_C).
