General Information

Overview

Introduction:K-Cdr

The following pages describe the K-Commander (K-Cdr ) pages orscreens for the loss-in-weight application. A listing of menu selections isprovided 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 givereality 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 whenimplemented, the controller continues tooptimize its operation , zeroing in, if you willon the best point of control.

Density Array A group of FeedFactors that are placed in anarray from Refill Complete to Refill Request.The values in the array are used to operatethe feeder during Refill.

Drive Command This is the frequency output of the LWF K10Scontroller that normally provides the setpointsignal to the MDU or motor drive unit. Thelarger the value of drive command, thegreater the feedrate should be. Maximumoperating value of Drive Command is 100%.




Overview, Continued

Definitionscon't

Term Definition

FeedFactor This is a calculation made by the controllerafter every weight conversion that gives anindication of the maximum flow rate of thefeeder 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, themassflow is compared to the setpoint, and ifdifferent, a change in drive command willoccur.

Massflow StandardDeviation

This is the variance of the massflow value ascalculated by the controller.

Measured StandardDeviation

This is the variance of the weight valuescaptured from the weighing system.

Refill CompleteWeight

The point, by weight, at which the refillingwill stop.

Refill Request Weight The point, by weight, at which the refillingwill begin.

STP Sample time period is the length of time for aweight sample to occur.

Tare The weight of the feeder and hopper, lessmaterial.

Volumetric control The control is manual. That is, the massflowis calculated if possible, but no comparison toSetpoint is made and the Drive Commandremains fixed.

Initial Feedfactor ` This value of feedfactor is used fortwo purposes:

1 ] To set Drive Command when inVol control by the formula.....

DC(%) = (SP/IFF )*100%

where SP = setpoint and DC =Drive Command.

2 ] The Initial Feedfactor multipliedby the Feedfactor Alarm Limitvalue is how much the AverageFeedfactor can wander without afeedfactor alarm.

ex: Initial Feedfactor (IFF) = 1000

Feedfactor alarm = 10%

Max Ave FF = 1100

Min Ave FF = 900

If the average Feedfactor goesbeyond the max or min limit, afeedfactor alarm results.

Range of Values 0 to 100,000,000Default value: 0.012







Average Feedfactor This is the computed value offeedfactor calculated by the LWFcontroller-in Mass/Grav. It is ameasure of the total estimatedcapacity of the feeder. It iscalculated as....

Ave. FF = (MF/DC%)*100%

MF= Massflow, DC = Drive Cmd.

If you see that the Averagefeedfactor does not change, thesystem is in Pert or the setpointdeviation is greater than 25%.

FF Hopper Empty If the Density or Feedfactor Arrayis "ON", then this variable showsthe computed running average offeedfactors when the hopper isnearly at the Refill Request/RefillMinimum point.

FF Hopper Mid If the Density or Feedfactor Arrayis "ON", then this variable showsthe computed running average offeedfactors halfway between RefillComplete/Maximum and RefillRequest /Refill Minimum

FF Hopper Full If the Density or Feedfactor Arrayis "ON", then this variable showsthe computed running average offeedfactors when the hopper isnearly at the Refill Complete/Refill Maximum point.







Density Array On/Off

`

This selection turns on or off theDensity/Refill Array system. TheDensity Array is a concept that isused to improve feederperformance during the refillsequence. The pop-up windowlooks like:

OffOn <

The < symbol indicates the choiceselected. Default value is "Off".

Feedfactor Alarm Limit

`

This is a percentage value that isused to provide an alarm if theaverage feedfactor goes outside thebounds as set by the product of thisvalue and the Initial Feed Factor.

ex: Initial Feedfactor (IFF) = 1000

Feedfactor alarm = 10%

Max Ave FF = 1100

Min Ave FF = 900

If the average Feedfactor goesbeyond the max or min limit, afeedfactor alarm results.

Note: If value is "0", the Feedfactoralarm is turned off.

Range of Values 0 to 1000%Default value: 0%







Calibrate DriveCommand

` This value is used to set drivecommand for feedfactorcalibration. If it is set to "0", thendrive command for feedfactorcalibration will =

DC% = (SP/AFF)*100

where SP = setpoint and AFF =average feedfactor.

This factor is not used for vibratoryfeeders.

Range of Values 0 to 100% Default Value: 10%

Calibrate Time ` Permits selection of feedfactorcalibrate time from 30 seconds to300 seconds. Pick a larger numberas the setpoint becomes lower. Formost cases, 60 seconds is a goodaverage choice. You may select atime interval however, that isrelevant to your process timing tobest understand how your feederwill really function in your process.

Range of Values 30-300 Default Value: 60







Calib. Correlation Limit A slow running average of thecorrelation from past runs takenduring feedfactor calibration basedupon a linear regression of thesample data computed during thecalibration time. An alarm isgenerated and the Initial Feedfactoris set to zero if the new correlationis below this number. To correct,enter a longer calibrate time thenincrease the calibrate drive cmd.

Last Calib. Correlation The correlation value capturedduring the last feedfactorcalibration. Look for consistency. Avalue of 100 is perfect, 90 is goodindicating consistent material flow,80 is indicating the flow is lessconsistent. The smaller the number,the less consistent the flow,possibly suggesting changing thefeeder type or feed screw if used.

Material Fed LastCalibration

The physical amount of productdelivered during the calibrationcycle. Divide this value by theCalibrate Time to compute themassflow rate. If you reset thetotalizer before starting, thetotalizer will give you the samevalue. Compare this value to theactual material weight deliveredduring the calibrate cycle. If theactual weight agrees with the valuedisplayed here, the feeder is alsocalibrated accurately by weight.

F3 Calibrate Cycle This function is special to loss-in-weight control. By using thecalibrate function, you candetermine the capacity of yourfeeder. The procedure forFeedfactor Calibration follows thissection.





Feedfactorcalibrationprocedure

This procedure permits step by step for feedfactor calibration. You dothis when running new or unknown material through your feeder andare unsure as to what the feed rate capacity of the feeder will be. Thistechnique will also produce information on accuracy of feedercalibration and to how well it will perform delivering material.

Step Action

1 Place new material in the feed hopper.

2 Enter a desired setpoint on page Mcn.00.

3 Go to page Mcn.01 and enter the Initial Feed Factor twicethe setpoint value. This will cause the feeder to run at 50%.

4 Put the unit in "Vol" control. Run the feeder until the feederis uniformly discharging material. Stop the feeder.

5 Go to page Mcn.01, enter desired Calibrate Drive Command.A value of 40-60% is recommended unless lower drivecommands are expected in normal operation.

6 Enter desired value of Calibrate Time in seconds. The defaultis 60 seconds. We suggest a time of 120 to 300 seconds.

7 Put an empty, tared container under the discharge.

8 Press F3- Calibrate Cycle. Feeder runs for the Calib Time.

9 When stopped, note the new Average and Initial Feedfactor.This tells you what the capacity of the unit is with thatmaterial. It also insures that when you begin operation, thefeeder will start close to its correct operating point and thatthe massflow will be near to the desired setpoint.

10 If the Last Calib Correlation is less than the CorrelationLimit, go to step 6 and increase the calibrate time. If thatdoesn't work, increase the Calibrate Drive Command in step5. A calib correlation above 90% is suggested to ensuresatisfactory feeder performance.

11 Weigh the delivered material and compare to the value inMaterial Fed Last Calib. If they agree, the feeder iscalibrated. If they don't agree, it is necessary to correct theweight span as indicated on page Mcn.05. Use this formulato calculate a new weight span, enter this value on pageMcn.05 and redo the calibration process.

New Span = old span *(container weight/mt’f fed last calib)

12 Put controller in Gravimetric control and run feeder.

Refill Enable ` No RefillRefill <

You select Refill to have theAutomatic function, if selected,continue to activate the refillingprocess. If you select "No Refill" ,no refill will occur and this willallow you to clean out the feederhopper with no problems. Thedefault value is " Refill".

Allowed Refill Time ` This entry sets the time period for anormal refill-in Automatic Refillmode- to occur. If the refill takeslonger than this entered value, analarm and an output from the RefillTimer Output will occur. Range of Values 5 to 240 secondsDefault value: 30 seconds







Refill Timer Option `DisableEnable <Terminate

Your selections:

Disable:

Disconnects any Refill Timeroutput from affecting the Alarmsystem. You get no Alarm from arefill failure.

Enable:

Connects the refill timer to thealarm system. You get an alarmwith a refill failure if set properly.

Terminate:

Terminates any alarm from therefill timer.

The default value is " Enable".

Refill Complete Weight ` This is the point at which anautomatic refilling system will stopadding material to the feederhopper. See the next section to seehow to set this value. Range of Values 0.01* Scale Range to0.95 * (Scale Range -Tare)Default value: 0







Refill Request Weight ` This is the point at which anautomatic refill system will beginto add material to the feederhopper. Please refer to the LWFControl section to see the chain ofevents that occur when the weightin the feed hopper reaches thispoint. Range of Values 0 to(Refill Comp - 2 of weight units).ex: 100-2 kgs = 98 kgsDefault value: 0

Post Refill Mode Delay ` This entry determines how long thecontrol will remain in "Vol" controlafter the refill is terminated. Thisdelay improves mass flow stabilityafter a refill. See a later section onhow to set this value. Range of Values 0 to 240 secondsDefault value: 5 seconds

Refill Mode ` ManualAutomatic <

You select Automatic if the LWF isrefill by machine, manual if youwill manually refill it. The defaultvalue is "Automatic".






Pert Value This value is directly related to theenvironmental noise. A highernumber represents more noise inthe weight signal. The minimalvalue is 0. When the feeder isstopped this value should be lessthan 5. When the feeder is runningthis value should be from 2-10. Asenviormental noise increases, thisvalue may increase to 20.

Basically this value shouldremain stable. If you note that thevalue is increasing or peaks, thismay cause massflow errors.

Refer to the Loss-in-WeightControl Theory manual #4002.There is a section that discussesPERT.



Refill Setup Procedures

Setting "RefillComplete"

This procedure will permit initial setting of the Refill Complete entry.You can trim the setting after you have run the system to optimizesystem performance.

Step Action

1 Determine the material bulk density , ex, 0.64 kg/L

or 40 Lb/ft3

2 Measure the feeder hopper volume, e.g. 140 L, or 5 ft3

3 Multiply volume by density to get maximum hopper storagecapacity(MHSC). e.g.: from step 1 &2,

MHSC = 0.64*140 = 89.6 Kgs or 40 * 5 = 200 Lbs.

4 Determine the net available weight capacity(NAWC) by:

NAWC = Scale Gross Weight Range - Tare

You will find these values on page Mcn.05.

ex: Scale Range = 264 Lbs, Tare = 122 Lbs, 120 Kgs, 55.35 Kgs

NAWC = 264-122 = 142 Lbs or 64.4 Kgs.

5 Use the smaller of the two calculated values. In this example,the hopper can hold more weight than the scale can support.Use the scale capacity number NAWC.

NAWC = 142lbs or 64.4 Kgs, MHSC = 200 lbs or 89.6 Kgs,therefore use NAWC value to set refill maximum.

6 Take the value from step 5 and multiply it by 0.7. This is theinitial value you program into the controller for RefillComplete Weight.

7 Run the system and use trial an error to optimize the RefillComplete point so that you do not overfill the hopper oroverrange the scale system. Good luck.




Refill Setup Procedures, Continued

Setting "RefillRequestWeight"

To set the Refill Request Weight, you can take 40% of the RefillComplete Weight and use that value as the Refill Request Weight oryou can follow this procedure.

Step Action

1 Find or measure the feeder hopper volume that is agitated. Ifthe hopper section is not agitated, measure the volume of theconverging section or cone. ex: 1 ft3 or 30 L.

2 Determine the bulk density of the material being fed. Fromthe above example, we measured 0.64 Kg/L or 40 Lb/ft3.

3 The Refill Request Weight is 0.64 Kg/L*30L= 19.3 Kgs. or

40 lb/ft^3 * 1 ft^3 or 40 Lbs

This is the minimum recommended value to be used forRefill Request. The Refill Request value could be as large as0.5 times the Refill Complete Weight value and still workwell.

Setting"Refill Timer"

Use this procedure to set the Refill Timer.

Step Action

1 Run the feeder through 3 refill cycles. Measure the time ofeach refill period. Average the values.

2 Increase the average by 25% and enter that value into therefill timer.

3 Test to see that the Refill Alarm does not actuate in normaloperation.




Refill Setup Procedures, Continued

Setting the"Post RefillMode Delay"

This is an empirical procedure to set the Post Refill Mode Delay. Thepurpose of setting this value is to minimize upsets to the mass flow ofproduct going into the process during and immediately after refill. Thedefault is 5 seconds and is OK for pelletized materials. For floodablematerials or liquids, the time will likely be longer. How do youdetermine the correct value? Please follow this next procedure.

Step Action

1 Monitor either motor speed or Drive Command from thecontroller. Be able to accurately record those values.

2 With the default setting in the Post Refill Mode Delay,operate the feeder through a refill. Note the deviation ofmotor speed or drive command during the time beginningimmediately prior to refill and ending a minute or so afterthe unit has switched to Mass control. If you not anunacceptable deviation, increase the time by a couple ofseconds and repeat the process. Continue this process untilyou get no additional major improvement. If the timebecomes excessive, select a value that is in your mind areasonable compromise. Record that entry.

Cleaning oremptying thefeeder hopper

To facilitate the emptying of the feeder hopper when in AutomaticRefill, select the "No Refill" selection for Refill Mode prior to the refillsystem actuating. This will prevent a refill from occurring and permitemptying of the feeder hopper.

Alarm Cause Remedy

Scale/SFT# "xx"Overrange Alarm

The scale orindividual SFT asidentified by the "xx"is in overrange.

SFT has weight on itgreater than itscapacity. Removeweight from the scaleor SFT.

Scale/SFT# "xx"Underrange Alarm

The scale orindividual SFT asidentified by the "xx"is in underrangecondition.

The gross weightreading is below zeroby more than the NetWeight Low(-)value.Generally a failurecondition in thetransducer or scalesystem. In a B scale,the counterweighthas shifted. Bindingor forced unloadingof the SFT may alsoresult in this problem.

Weight ProcessorFailure Alarm

Controller is notreceiving a weightsignal from SFTs towhich it is connected.

Many problems cancause this situation.An SFT failure, aScale Interface Pcfailure, a powerfailure to the SFT orscale Interface Pcboard.






Alarm Cause Remedy

Net Weight LowAlarm

Actual weight inhopper is less than

2%(Scale Range-Tare)

This value isprogrammable from0.0% to 10.0% of thevalue (Scale Range-Tare).

This means, if tare iscorrect, that thefeeder hopper isnearly empty. Manycauses are possible.

Tare and Span Calibration Procedures

Tarecalibrationprocedure

To tare the machine, please follow the next procedure. If you have thevalue of tare already available, enter that value in the Feeder TareWeight position.

Step Action

1 Empty feeder hopper

2 Press key F3 - Tare button.

3 Note that the Material Net Weigh is nearly zero.

4 Record the value of Feeder Tare Weight for future reference

5 Fill machine hopper and operate feeder.

Spancalibrationprocedureusing weights

This procedure for checking the scale calibration uses weights.

Step Action

1 Note the current material net weight reading

2 Add an accurate known weight to the machine. Use a weightthat is at least 10% of the scale range for this activity. Thematerial net weight reading should increase by that amount.

3 New weight Span =

Current Weight Span *(Applied weight/Displayed weight)

ex: If current weight span is 0.9, the weight applied to thescale is 100 kg and the displayed weight reading is (350-249)or 101 Kg then

New weight Span = 0.9*(100/101) = 0.891

4 Enter the calculated weight span number into the WeightSpan variable.

5 Check the material net weight change again after enteringthe new span value to make sure that the weight increaseyou see agrees with the value of the weight you applied tothe scale.




Tare and Span Calibration Procedures, Continued

Spancalibration bytaking ratesamples

You can also set the weight span by taking weight samples. This isprobably not quite as accurate as the method using a known accurateweight.

Step Action

1 Put material in the feed hopper.

2 Place the machine in Gravimetric control.

3 Put in a desired operating setpoint.

4 Run the feeder for a period until the massflow and drivecommand values are stable.

5 Take 5, 1 minute catch samples in a row.

ex: 3.66 kg, 3.56 lkg, 3.58 kg, 3.60 kg and 3.59 kg

6 Add up the samples and divide by the number of samplestaken to get the average sample value.

Total = 17.99 kg and divide by 5 samples = 3.598 kg/sample.

7 Recalculate the setpoint into the same time units.

ex: Setpoint = 220 kg/hr = 3.666 kg/minute

8 Calculate the new span using the current span in thefollowing formula.

New Span = Current Span*(Sample Ave./ Setpoint) =

ex; Current span = 1.005

New Span = 1.005*(3.598/3.666) = 0.986

9 Enter calculate span into the variable Weight Span

10 Repeat steps 5 to 8 to check that the span is OK. If not, redothe calculations, enter new span as in step 9, and redo steps5-8 again.




Tare and Span Calibration Procedures, Continued

Totalizermethod forspancalibration

To set the span by using the totalizer is another way to calibrate thefeeder.

Step Action

1 Put the unit into Gravimetric control at some desiredsetpoint.

2 With material in the feeder hopper, run the feeder and allowmaterial to flow from the feeder in a uniform flow pattern.Be sure that the massflow rate and drive commande arequite stable. Stop the feeder.

3 Clear the totalizer. Be sure that you have a large container tocatch the flow of material during this run.

4 Start the feeder.

5 When the container becomes full, stop the feeder.

6 Note the totalizer reading

7 Weigh the contents of the container

8 Compare the container weight to the totalizer. They shouldmatch.

9 Calculate the new span setting from the following equation:

New Span =

Current Span*( Container Weight/Totalizer Weight)

ex: Current span = 1.004, Container weight =99 kgs, thetotalizer reads 100 kgs.

New span = 1.004 * ( 99/100) = 0.994

10 Enter the new span.

11 Redo steps 3-9 to check the accuracy of the new span value.

12 You have calibrated the feeder. You can now run the feederin production.

These outputs can be configuredfor a number of different functionsas shown. The scaling chart followsthis section. Default value is " NotAssigned".

Frequency Input 1-2 Not Used

Frequency Input #3 ` This is the ratio or direct setpointinput for the controller if use.

Frequency Input #1-#3Value

These variables show the incomingfrequency at these inputs.

Scaled Frequency Input#3

This is the frequency value of Input#3 after it has been scaled by theScale Factor for Input #3.







Scale Factor Input #3 ` This value scales the incomingfrequency as presented to Input #3.The frequency will be used toprovide the ratio or direct controlsignal as set on page 07. Theprocedure on how to set this valueis described in DCS#322.

Range of Values 0 to 999Default value is 1.000

Frequency In #3Deadband

` This value sets the variation level atwhich the frequency signal will beignored. For example, if the entry isset to 10 Hz, any frequency input toInput #3 that varies less than 10 Hzwill be recognized as non-changing.

Range of Values 0 to 1,000,000,000 HzDefault value is 1 Hz





Frequencyouput scaling

The following table indicates the equations for frequency outputs forthe LWF application. Note: FSS = Full Scale Setpoint from page 07.

Frequency Name Equation for Output

Massflow Fo = (Massflow/FSS) * 10kHz

ex: Fo= (5000Kg/Hr/10000Kg/Hr) *10kHz

Fo = 5000 Hz.

Setpoint Fo = (Operating Setpoint/FSS) * 10kHz

ex: Fo= (3000Kg/Hr/10000Kg/Hr) *10kHz

Fo = 3000 Hz.

Weight on Scale Fo =

(10kHz/Scale Range)*Actual Net Weight

ex: Fo= (10kHz/120kg)*43Kg = 3583 Hz

Deviation fromSetpoint

Fo = 5Khz + 10kHz*(Massflow Error/FSS)

ex: Massflow error = -50 Kg/Hr:

Fo = 5 kHz + 10kHz(-50/10000) = 4950Hz

Note sign of the massflow error.

Drive Command Fo =

10Khz* (Current Drive Command%)/100%

ex: 10kHz *( 43%/100%) = 4300 Hz.

Screw Speed Fo = Motor speed frequency/(# of GearTeeth*Total Reduction)

ex: Fo = 3200/(120*1) = 26 Hz

Density Factor Fo =

(5Khz/Initial Feedfactor)* Ave. Feedfactor

ex: Fo = (5000/1000)*343 = 1715 Hz.

The following is a listing and description of each variable on this page.A "` " mark shows the values that you can edit. A "#" indicates that thevalue is changed by a Function key. A $ symbol indicates that the valuecan be changed but you should let the controller do it for you.


Weight Sample Time(msec)

$ This value sets the length of theweight sample time period. Thesmaller the setpoint as a function ofthe gross scale range, the larger thisnumber should be. The value 4500msec is the maximum entry. If theAdaptive Tuning is Enabled, thisvalue is calculated for youautomatically. Range of Values 500 to 4500 msec

Massflow StandardDeviation

$ This value represents the squareroot of the 2 sigma weight residualcalculations as done by the Kalmanfilter. The larger the number, thepoorer the environment is treatingthe feeder. The smaller the numberthe more accurate is likely themassflow result. This number iscalculated by the Kalman filterwhen the Adaptive Tuning isenabled. Numbers in the range of20-50 are good. Numbers largerthan 100 require work to be done tothe installation to reduce thevibration to the feeder. Range of Values 1 to 999







Desired Std Deviation $ This value is a function of thevariation of the massflow data andis used by the controller to set theKalman filter gain function foraggressive or sluggish control. Thisnumber is calculated by theKalman filter when the AdaptiveTuning is enabled. Range of Values 01. to 500

Motor Control Gain $ This number sets the Integral gainof the controller. The large thevalue , the more aggressive thecontrol action. This number iscalculated by the Kalman filterwhen the Adaptive Tuning isenabled. Range of Values 1 to 999

Massflow Filter Length ` The larger this value is, the morestable the massflow display will be.This value has no affect on control. Range of Values 1 to 300 secondsDefault value is 5 seconds







Adaptive TuningEnabled

` OffOn <

It is recommended that theAdaptive Tuning be left on for alloperations. Selecting "off" results inno updating of the Kalman filterdata and potential less thanoptimal performance by the feedercontroller. Default value is "Off"

Feeder Run Time ` This is the length of time in hoursthat the feeder has been runningsince the variable was cleared.Enter the value of "0" to clear thevariable.

Drive Command Ceiling Sets the maximum motor drivecommand. The range is: 0 to 125%.The default is 125%.

Basics of SPCoperation

Each point indicated on the chart is an average of the number ofsamples of the selected variable specified by the sample widthparameter set on pg Mcn.11. Samples are taken every two seconds. Theamplitude of the points on the chart (in pixels) is equal to:

Amplitude = 2000*(chart scaling factor)* Deviation from target

where chart scaling factor is set on page Mcn.11.

The height of the chart between zero deviation and either dashed line is100 pixels.




LWF Page 12: SPC Chart, Continued
