A.3 Determining the Software Setup Factor
The Digital Dosing control unit is configured via a Software Setup Factor (binary code). To
determine the Software Setup Factor answer the following questions: If the answer is “yes”
enter the code number in the selection column. If the answer is “no” enter “0” in the selection
column. When all the questions have been answered and the selection column is completed,
add up the total for the selection column. The total is the Software Setup Factor.
A.4 Recipe Formulas
The following formulas can be used to determine if a recipe is appropriate or possible.
Injection Molding
For injection molding applications, compute the dosing disc speed and total number of disc
revolutions using the following formulas. Recipe limitations are listed in the table following
the equations.
Disc RPM
(Shot Weight - g) x (Additive - %) x 0.6
(Disc Calibration Weight - g) x (Recovery Time - s)
=
Disc Revolutions per Shot
(Shot Weight - g) x (Additive - %) x 0.01
(Disc Calibration Weight - g)
