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 29.
CAUTION
:
!
Calibration must be performed when the product in the barrel is completely liquid. There must not be any ice on the
scraper blade.

Select DFRST on the Barrel Status menu (Figure 13.). It is very important that cali-
bration be performed on a fully defrosted barrel (outlet temperature must be 41
°
F or
barrel must be purged and refilled with new product).

brated.
