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.

Figure 5. Electrical Diagram

Extrusion - Constant: Wire the cycle/run slave cable (thin two- conductor cable) to a set of DRY (NO VOLTAGE) contacts that CLOSE when the screw rotates. See Figure 5 for electrical diagram.

Extrusion - Proportional: Wire the cycle/run slave cable to the extruder signal output that is proportional to the extruder speed. The signal output can be one of the following: 0-10 VDC or 0-20 mA. Please refer to the labels on the cycle/run slave cable for the correct input to avoid damaging the controller. Digital Dosing Additive Feeder should be configured from the factory for each specific input. See Figure 6 for analog inputs.

NOTE: Voltage from Extruder needs to be isolated. Consult factory for other signal requirements. External signal converter may be required.

NOTE: Zero input corresponds to zero screw speed and no additive dosing. Maximum input corresponds to maximum screw speed.

NOTE: If a 0-10 kHz frequency input is used, it must be a square wave width and an amplitude of 12 VDC. The shape of the signal is important, especially above 7,000 Hz.
