Calibrating a Motor
Calibration of motors is typically required when a motor or any associated barrel components (i.e., scraper blades,
seal, faceplate, etc.) is removed or replaced. Calibration establishes a new baseline for the motor assembly. This
allows the system to determine proper viscosity settings for the new motor. When a new motor is installed in the
unit or any of the barrel components are changed or adjusted, the motor should be calibrated by performing the
procedure described in Table 31.
!
CAUTION:
Calibration must be performed when the product in the barrel is completely liquid. There must not be any ice on the
scraper blade.
System Menu
The System menu is used during production to set up the unit. It also allows the technician to view and change the
number of barrels, the number of compressors and the number of pressure sensors present in the system, as
shown in Figure 29. The description of these items is shown in Table 32.
NOTE: Changing these values to a number that doesn’t match the physical number of items in the
system generates errors or turns off some of the equipment present in the system.
When the individual fields are highlighted, the display buttons change. Refer to Table 33 for a listing of the button
functions for the various field selections.
Table 31.
Step
Action
Procedure
1
Re-assemble barrel
It is VERY IMPROTANT that calibration be performed
when the product in the barrel is in a 100% liquid
state. There can be no ice in the barrel or on the
beater bar.
2
Defrost the barrel
Select DFRST on the Barrel Status menu (Figure 8).
It is
very important
that calibration be performed on
a fully defrosted barrel (outlet temperature must be
41
°
F or barrel must be purged and refilled with new
product). Selecting DFRST while the barrel is off ini-
tiates a full defrost cycle.
3
Select Motor Setup
Use the Up and Down arrows to highlight MOTOR
SETUP on the Maintenance menu.
4
Select the barrel
Use the Up and Down arrows to highlight the desired
barrel
5
Start calibration
Press the CAL button at the bottom of the Motor
Setup menu to start the calibration process.
6
The calibration cycle continues for five (5) minutes to
allow the gearbox to stabilize at temperature and
ensure correct calibration. At that time the motor
stops and it is calibrated.
7
Complete the procedure
Press the BACK button at the bottom of the display to
return to the Maintenance menu.
