6. EXTRUSION – “Simple”: Connect the input cable (2-conductor cable-gray) to a dry contact (zero voltage) signal that indicates the extruder screw is turning. (The connection in the controller should be on terminal block #10 and PLC input X5.. A jumper wire can also be installed on the same terminals (instead of a dry contact.) if the feeder is to be started and stopped through the feeder controller, and not with the extruder screw. 7.

Screw Recovery Time. The screw recovery time is the estimated screw recovery time, and is used as the initial value for validating the recipe. Actual screw recovery times as measured by the presence of the screw recovery signal, are used to fine-tune the feed rate during operation. The estimated time must be at least ½ of the actual recovery time. If less than ½, the feeder will interpret the recovery signal as a purge cycle. Calibration weight. Calibration weight is determ
