Typical Start-up
Upon a first time start-up of the process, the throughput control system is placed in the Manual
Mode. The LIW controller learns the rate of the material flow through the mass flow hopper within
45 seconds and enters the logarithmic value in the control parameters. The controller will display
the learned throughput rate and indicate the process can be switched into the Auto or Locked
Mode. A target value for the process throughput desired is entered as a set point on the LIW
controller. The system can be switched into the Auto or Lock Mode and the speed of the extruder
will be adjusted to maintain the target process throughput. If a change to the process throughput is
required the new target is entered and the controller will instruct the extruder drive to increase
crease or decrease respectively. The reaction of the LIW system to the process rate change is
almost instantaneous and will settle at the desired throughput within 45 seconds of the process
reaching the requested target.
Once the LIW controller learns the throughput rate of a material, it is stored in the memory of the
controller. The controller can be left in the Auto or Locked mode if the same material is continued
or a similar bulk density material is used. If a new material with a different bulk density is used, the
start-up procedure must be re-initiated.
Components
