Setting the TQC
Step 1
Locate the L1 power path passing through the TQC to
the beater motor (socket connection #5and #6). Install
an amp meter on the L1 power path to monitor the
amperage of the beater motor.
Step 2
T urn the viscosity adjustment potentiometer clockwise
to the coldest setting.
Step 3
With the freezer properly primed, activate the
refrigeration syst em.
Step 4
During the freezing process, draw samples and
inspect the product appearance. When the desired
product viscosity and appearance is achieved, note
the beater motor amperage.
Step 5
Slowly turn the viscosity adjustment potentiometer
counterclockwise (warmer) to cycle off the
refrigeration syst em.
Step 6
Draw several samples to verify the amperage at
cycle-off time and the product appearance remains
consistent.
TQC Range Setting
The same TQC is used in many different freezer
models which have a variety of electrical
specifications. For this reason, the TQC must be set
to operate in an amperage range which relates to the
beater motor amperage and the desired product
viscosity setting.
The selected amperage range simply determines the
adjustment span of the viscosity adjustment
potentiometer on the face of the TQC.
There are four range selections to choose from as
shown on the range selection chart.
Range Selection Chart
Range (Amps) Cut Jumpers
1.2 -- 2.4 White, Blue and Yellow
2.5 -- 5.0 White and Blue
4.0 -- 8.0 White
5.7 -- 11.4 None
On thefront ofthe TQC, there are three colored jumper
wires (white, blue and yellow). The proper range
selection is determined by running the freezer to
determine the beater motor amperage when product
reaches the desired viscosity, and cutting the jumper
wire(s) indicated on the range selection chart.
Before jumper wires are cut, use the following
procedure to determine the proper range selection.
Step 1
Locate the L1 power path passing through the TQC to
the beater motor (socket connection #5and #6). Install
an amp meter on the L1 power path to monitor the
amperage of the beater motor.
Step 2
T urn the viscosity adjustment potentiometer clockwise
to the coldest setting.
Step 3
With the freezer properly primed, activate the
refrigeration syst em.
Step 4
During the freezing process, draw samples and
inspect the product appearance. When the desired
product viscosity and appearance is achieved, note
the beater motor amperage and then place the freezer
control switch in the “OFF” position.
Step 5
Compare this amperage reading with the range
selection chart. Determine the range to which the
amperage reading applies.
Note: Select the center of the range that is closest to
the noted amperage.
Step 6
Cut the jumper wire(s) which correspond with the
range selection.
Step 7
Start the refrigeration system again, and observe the
beater motor amperage. When the amperage reading
reaches the desired product viscosity, slowly turn the
viscosity adjustment potentiometer counterclockwise
(warmer) until the refrigeration system cycles off.
Step 8
Draw several samples to verify that the amperage at
the off-cycle and the product appearance remain
consistent.
Note: If the wrong wire is cut when setting the
amperage range selection, simply solderthe wireback
together .
