moisture. 
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.

•  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 6 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: 0-10VDC or 0-20mA.  Please refer to the labels on the cycle/run slave 
cable for the correct input to avoid damaging the controller.  Digital Dosing 
Additive Feeder is configured from the factory for each specific input.  See Figure 5 
for the electrical diagram for voltage inputs.  See Figure 6 for frequency inputs.  
NOTE: Voltage from Drive needs to be isolated.  Consult factory for other signal 
requirements.  External converter signal may be required.
