Throughput control of the extruder
|
Throughput control of the extruder is a configurable basic function of
the GraviMaster. To start with the screw speed is set by hand. If the
throughput is within tolerance limits the system can be driven in automatic
mode. The function is comparable with an electronically controlled
potentiometer.
The automatic/manual strategy is selectable:
- manual switch-over to automatic mode within the tolerance band.
- manual switch-over to automatic mode within or outside the tolerance band.
- self-acting switch-over to automatic mode within the tolerance band
- set-point tracking in manual mode
