General Information
Overview
Introduction:
K-Cdr The following pages describe the K-Commander (K-Cdr ) pages or
screens for the loss-in-weight application. A listing of menu selections is
provided for each screen. This document is suitable for rev. Z software.
In this chapter Please note that the page numbers beginning with 01 is merely to give
reality to the display and this number could range from 01 to 15.
Definitions Here is a listing of common terms used in loss-in-weight feeding.
Term Definition
Adaptive Tuning This is a control concept that when
implemented, the controller continues to
optimize its operation , zeroing in, if you will
on the best point of control.
Density Array A group of FeedFactors that are placed in an
array from Refill Complete to Refill Request.
The values in the array are used to operate
the feeder during Refill.
Drive Command This is the frequency output of the LWF K10S
controller that normally provides the setpoint
signal to the MDU or motor drive unit. The
larger the value of drive command, the
greater the feedrate should be. Maximum
operating value of Drive Command is 100%.

Term Definition
FeedFactor This is a calculation made by the controller
after every weight conversion that gives an
indication of the maximum flow rate of the
feeder when drive command is equal to 100%
It is calculated as:
FeedFactor = (MF/DC%)*100 where
MF= Massflow and DC = Drive Command.
Feedrate This is the massflow output of the feeder.
Gravimetric control The control is automatic. That is, the
massflow is compared to the setpoint, and if
different, a change in drive command will
occur.
Massflow Standard
Deviation This is the variance of the massflow value as
calculated by the controller.
Measured Standard
Deviation This is the variance of the weight values
captured from the weighing system.
Refill Complete
Weight The point, by weight, at which the refilling
will stop.
Refill Request Weight The point, by weight, at which the refilling
will begin.
STP Sample time period is the length of time for a
weight sample to occur.
Tare The weight of the feeder and hopper, less
material.
Volumetric control The control is manual. That is, the massflow
is calculated if possible, but no comparison to
Setpoint is made and the Drive Command
remains fixed.

Standard Key Arrangements
Introduction Many keys are the same and used in the same way on each screen. This
map will describe the often used keys and each page section will
describe those keys unique to that page. Here is a typical key layout for
viewing.

Number Key Name Description
F1
Grav Mode
Places the control in Gravimetric or
Mass control. The LWF Controller
measures the massflow, compares
this value to the setpoint and
causes the Drive Command to
change so that the massflow will
equal the setpoint
F2
Vol Mode
When operating in Volumetric
control, the Drive Command is
fixed. There is no attempt by the
controller to make the massflow
value equal the setpoint.
F3 Unused
F4 Unused
F5
Edit Mode
When pressed, highlights the first
variable that can be changed. The
switch then becomes "Change
Value".
