Section 1: Introduction This User’s Manual is intended for use with the Digital Dosing Disc Additive Feeder. The feeder precisely meters and controls the addition of master batches, chemical additives, and regrinds to primary plastics. The Digital Dosing unit can meter both powder and granular material of various sizes. It can be used on extrusion, blow molding and injection molding machines.
Figure 2.
1.1 Controller The Digital Dosing additive feeder consists of a controller(s), dosing motor(s), and feeder(s). The controller is used to: • Configure the unit to the desired process. • Calibrate the feeder • Run, monitor, and stop the dosing process • Enter, recall, and run recipes • Troubleshoot problems via error codes A keypad and LED display (see Figure 3) are used to enter, or change, data. • The control system is switched on (position “1") with the On/Off switch.
1.2 Keys and Symbols Recipe Storage/Recall: For saving, recalling or modifying recipes. Stop: Stops the continuous operation of the feeder. Will reset the totalizer showing metered amount of additive to zero if depressed for two seconds. Up-arrow: For increasing the set value in decimal increments. Down-arrow: For decreasing the set value in decimal increments. Arrow Key: For fast increasing/decreasing of the set value in larger increments. Must be pressed simultaneously with the up- or down-arrow.
Symbols Lights when the run signal from the process machine is received by the Digital Dosing controller. During operation, lights when the disc is dosing material. During calibration and recipe input/viewing, lights when a calibration weight is input or viewed. (EXTRUSION ONLY) Lights when a screw speed signal is received from the extruder during proportional extrusion control (tracking, or following) Lights when an alarm occurs.

Section 3: Initial Installation and Operation 3.1 Initial Installation Hopper Piece Processing Machine Direction of Material Flow Figure 4. Digital Dosing Unit Assembly 1. The Digital Dosing additive feeder is not affected by machine vibration, therefore best performance is achieved by mounting the unit directly to the feed throat of the molding machine or extruder (see Figure 4). The inlet into the process machine must be greater than 2” diameter; otherwise, an adapter might be necessary.
4. Electrical connection to process machine: • Injection Molding: Connect the cycle/run slave cable (thin two-conductor cable) to a set of DRY (NO VOLTAGE) contacts that CLOSE for the duration of screw recovery. See Figure 5, electrical diagram. J12-3 J12-2 Relay contact Injection molding Machine Digital Dosing controller (Electrical diagram of connections) Figure 5.

3.6 Calibration All feeders must be calibrated before any blending recipes can run using the Digital Dosing additive feeder. NOTE: The calibration weight (metered material weight for one revolution of the dosing disc) must be determined separately for each material to be dosed since calibration weight differs from material to material. The following equipment is needed for calculating the calibration weight: • Scale with a minimum accuracy of 0.
• This sample should be returned to the material hopper without weighing. This sample is used only to ensure that all disc pockets are completely filled. • Replace container in calibration box (or under material outlet tube) • Press • The disc will rotate one full revolution. After the disc has stopped rotating, a Step 3: to take a sample for weighing. number in the format “xx.xx” will appear on the screen along with a flashing and “g.
Step 6: After the fifth calibration sample press “ RUN “ the controller will automatically finish the calibration cycle and be ready to run. The following are methods used to interrupt the calibration cycle. • Pressing the stop button will stop proportioning and not accept the calibration weight. • Pressing the calibration button will stop proportioning and accept the calibration weight. NOTE: It is normal for calibration weights to vary slightly from sample to sample.
