GEARSWITCH
Note:
Not used for vibratory feeders
Defines how the unit will change gear reductions on the K2 feeder
with motor reversing gear reduction switching. To activate, a digital
output must be set to <HILoGear>. Selections are:
High, Low, Auto Hi, Auto Lo
Notes:
• See more detail of operation section 5.1.1.
• To fix the reduction at either High or Low speed, select either High
or Low entries.
• This value is only displayed when internal KCM motor drives are
used.
• <Low> selects low speed/highest gear reduction.
• <High> selects high speed/lowest gear reduction.
• <Auto Hi> When entering a setpoint which will generate a drive
command of more than 50% and the GEARSWITCH is on Auto
Lo, the gear will switch to high and the GEARSWITCH parameter
changes to Auto Hi.
• <Auto Lo> When entering a setpoint which will generate a drive
command of less than 10% and the GEARSWITCH is on Auto Hi,
the gear will switch to low and the GEARSWITCH parameter
changes to Auto Lo.

AUTO FF CALIB This action permits easy feeder calibration. For this the program
parameter <CAL DC> and <CAL TIME> have to be entered. Material
is discharged for the value of <CAL TIME> and the starting feeding
factor is calculated.
Notes:
• Calibration can be canceled with STOP.
•PressingENTER instead of RUN as noted above will abort the
AUTOFFCALIB routine and return the user to the HOME menu.
• Performing an AUTOFFCALIB function on an already running
feeder will have no effect upon operation.
▲This command will start the feeder. Make sure that nobody is
working on the machine.
For KSU-II/KCM select this parameter, press ENTER twice
and then press RUN
For KSL press MORE-F5 then press then press RUN.
For KSC press then RUN.
Attention:
Refilling and feeding errors during calibration reset the program pa-
rameter FF INIT to <0> and activate the <FEEDFACTOR ERR>
alarm.
CALIB REMAIN [s] A count down timer for the auto calibrate cycle. It shows how many
seconds are left in the Calibration cycle.
INIT FF
Initial Feedfactor
Input of the starting feeding factor to determine the motor speed. The
Drive Command is calculated as follows:
DriveCommand(%) = 100 x (Setpoint/Initial Feedfactor)
The starting feed factor can also be calculated with the command
variable <AUTO FF CALIB>. Value of <0> will cause a Feedfactor
Alarm.

BULKDENSITY
Bulk Density
If the variable <VOL RATE>, in the <SERVICE VARIABLE INDEX>,
is set any value other than <0>, this variable will be displayed.
As the feeder runs in gravimetric control, the Bulk Density value will
be updated by the calculation: BD = FF/VOL RATE
Note:
To use this variable, do the following:
1. Enter the bulk density (BD) of the material being fed.
2. Perform an Auto Feedfactor calibration. The result is the value
<VOL RATE>, calculated as the ratio of Feedfactor (FF) /
Entered Bulk Density. The value <VOL RATE> is found in the
Service Variable Index.
When the feeder runs in gravimetric control, the <BULKDENSITY>
parameter will reflect the current material bulk density.
EMPTY FDR Empty feeder function. When started, the feeder runs at a drive
command of 70%. The feeder stops automatically if no weight loss is
detected.
Note:
<Empty Drive Cmd> may be changed by the Service Variables.
▲This command will start the feeder. Make sure that nobody is
working on the machine.
For KSU-II/KCM select EMPTY FDR, then press ENTER
twice then RUN .
For KSL press MORE-F5- then press then press
RUN.
For KSC, press the then RUN.
Notes:
• The <EMPTY FDR> action can be halted with the STOP key.
• The Net Weight Low alarm is also generated when the Empty Fdr

ACTIFLOW CALIB ActiFlow calibration function
1. Fill the feeder with material.
2. Set material characteristic “Easy, Medium, Hard or Manual“ in
the KCM ActiFlow menu.
3. Run the ActiFlow calibration.
Notes:
• This calibration routine will run a frequency sweep on the ActiFlow
to find the mechanical resonance point of the feeder. During the
calibration is no material fed.
• Its important to have the feeder filled with material to a normal
operating level before running this step, because the resonance
point is significantly affected by material.
SCREW FILL When started, the motor will run (At the Calib DC) until weight loss is
detected. Then the motor automatically stops.

AVG FF
Average Feedfactor
The value shows the estimated mass flow value expected at 100%

AverageFeedfactor = 100 x (Massflow/DriveCommand(%)
Average Feedfactor represents the massflow capacity of the feeder
and is affected by bulk material characteristics and the current
feeder mechanical configuration.

REFILL ARRAY
Feedfactor Array or
Density Array
ON Refilling feedfactor storage array is on. The feeding
factor values are stored in these registers when the
gravimetric mode is active. During refilling, the stored
feeding factor values in conjunction with setpoint are
used to establish proper drive command.
OFF The refilling feedfactor storage array is off. The last
average feedfactor just prior to refill is used in
conjunction with setpoint to control feeding during
refilling.
Input range: On or Off Default: Off
Notes:
• When <ON>, the Refill Array routine checks that the array FF
Empty and FF Full are within 0.5 to 2.0 times the current average
feed factor, otherwise the FF array is cleared.
• If the feed factor changes more than 15% (0.5 times the service
variable RefArr DevLim), the refill array is cleared.
FEED FACT 1, 5, 9
FF Hopper Full
FF Hopper Mid
FF Hopper Empty
Display of the feeding factor values in the refilling feedfactor array.
These factors are calculated in the gravimetric mode and used
during refilling in the volumetric mode when the refilling array
registers are activated.
Full(9) = 10% below the top refilling limit.
Middle(5) = 50% below the top refilling limit.
Empty(1)= 10% above the lower refilling limit.
Note:
Consistency of values indicate little variance in bulk material flow
properties. This is ideal. Rapidly changing bulk density can affect
feeder performance over the refill range. This would be evidenced by
widely varying values of feedfactor. If the values vary highly,
consider modifying refill levels, both maximum and minimum, to
achieve more consistent feedfactors over the refill range.
