3-2 Initial Operation

The control system is factory-programmed. However, specific values need to be verified prior to operation (basic parameter settings). The input values will be saved and still be available if the feeder is switched off, or a power failure occurs. Please refer to Appendix B for these values.

Extrusion operations require a “span factor” to be entered into the basic settings. These are also explained in Appendix B.

Prior to putting your new Digital Dosing feeder on-line:

Configure the feeder control for motor speed, encoder pulses, sensors, and alarm

options.

Tune the drive.

Enter a recipe.

Calibrate the additive weight for best accuracy.

NOTE: Recipe parameters are different for Injection Molding, Extrusion –

Constant, and Extrusion - Proportional operation. See each individual section for details.

Once the feeder is on-line, recipes can be saved for later recall (up to 50 standard).
