Refill Algorithms for the KCM
Refill modes selections include:
– Manual
– Automatic-Auto
– Automatic_Terminate
Refill Mode: Manual
Manual refill mode is designed for those applications, particularly for
low federate applications where bulk material will be randomly added
to the feeder.
The KCM is always in gravimetric control mode. The KCM switches to
Volumetric control when the hopper weight drops below the Net
Weight Low (NW Low) value. If the Refill Window remains active the
Refill Timer times out and activate the refill timer output. As shown
above the value RT is the Refill Timer setting. When the net weigh
drops below the NW Low value, the controller switches to VOL control.
