Calibrating a Motor
Calibration of motors is typically required when a motor or any associated barrel components (i.e., scrapper 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 55.
CAUTION:
!
Calibration must be performed when the product in the barrel is completely liquid. There must not be any ice on the scraper
blade.
Table 55.
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 39). 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).
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 pro-
cess.
The calibration cycle continues for five (5) minutes to allow the gearbox to stabilize at tem-
perature and ensure correct calibration. At that time the motor stops and it is calibrated.
6
Complete the procedure
Press the BACK button at the bottom of the display to return to the Maintenance menu.
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 60.
The
description of these items is shown in Table 56.
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 56 for a listing of the button functions for
the various field selections.
