General Information for Weigh Belt Feeder (WBF)Programming with K-Cdr.

Overview

IntroductionK-Cdr

The following pages describe the K-Commander (K-Cdr ) pages orscreens for the weigh belt feeder application. A listing of menuselections is provided for each screen.

Definitions Here is a listing of common terms used in loss-in-weight feeding andcontrol.

Term Definition

Belt Loading This is the weight of material per length ofbelt. Measurement is in kg/m or lb/ft.

Belt Speed This value is the measured speed of theweigh belt in m/min or ft/min.

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. Maximumoperational value of Drive Command is100%.

Feedrate This is the massflow output of the feeder.

Definitionscon’t

Term Definition

Gravimetric control The control is automatic. That is, themassflow is compared to the setpoint, and ifdifferent, a change in drive command willoccur.

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

Tare The weight of the feeder and hopper, lessmaterial.

Total Gear Reduction This is the reduction value of the inlinereducer and sprocket set on the feeder.

Transport Delay This is the time delay from belt loadingcalculation to the time that that value is usedto calculate belt speed. This function is use tomove the weight measurement electronicallyto the feeder discharge.

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

WBF Belt Factor, Page 01, Continued




Belt Load Setpoint • This value is used for twofunctions. First, in Vol Control, thisvalue is used to determine drivecommand. The formula is:

DC(vol) = [SP/(BLS *k)]*100%

where DC = Drive Command, SP =setpoint, BLS = Belt Load Setpointand k = a scaling factor that is notknown.

The factor BLS is also used to scaleBelt Loading if the display in % isdesired. The Formula is:

Belt Load(%) = 100*BL/BLS

where BL = actual belt loading andBLS = belt load setpoint.

Range of Values 0 toDefault value: 0







Totalizer DeadbandLimit

• This value sets the limit for whichbelt loading will be totalized. Forexample, if actual belt load is lessthan this limit, the displayed beltload will be zero. This prevents thetotalizer from recording erroneousvalues when the belt runs empty. Range of Values 0 toDefault value: 0

Beltloading This is the actual belt loading asdisplayed on page 00. Units areKg/meter or Lb/ft.

Material Fed inCalibration

This is the totalized amount ofmaterial fed during the calibrationcycle.

Calibration Correlation This is a percentage value thatrepresents a level of confidence inthe calibration results. The numbershould be between 90 – 100%.

Calibration Time This is the duration of the autocalibration cycle. 60 seconds is thedefault.

Calibration DriveCommand

This is the percentage of maximummotor speed used during thecalibration cycle. We recommend avalue between 40-60%.





Setting drivecommand invol control

This procedure permits step by step for setting drive command in Volcontrol. You will do this action when setting the Motor Drive Unit or tospecifically set a desired drive command when in Vol control. Note thatdrive command directly sets belt speed.

Step Action

1 Put the unit in "Vol" control.

2 Put the operating setpoint on page 00.

3 Determine the drive command that you desire

4 Enter a value of Belt Load Setpoint-BLS- on page .01

5 Run the feeder and read drive command.

6 Read Drive Command.

Drive Command Status What to do?Too High Increase Belt Load SetpointToo Low Decrease Belt Load Setpoint

7 When you have established the desired drive command andbelt speed, record the setting of BLS

8 You can now run feeder in Mass Control

Pre-Feeder DC Span • This entry will scale an outputcalled Pre-feeder Drive Commandto be a desired frequency with aspecific belt speed of the machine.The bigger the span, the higher thepre-feeder speed will be with agiven belt speed. Range of Values 0 to 10,000Default value is 1.000

Prefeeder set-up

Using a prefeeder requires that you set a frequency output #1-3 on pageMcn.08 to "Prefeeder", connect this signal by some means at theappropriate I-O point to the prefeeder and then use the Prefeeder D.C.Span to cause the belt loading to increase or decrease as you increase ordecrease the Prefeeder D.C. Span. As Prefeeder D.C. Span increases, thesignal from the selected frequency output also increases causing theprefeeder to deliver more material.

This entry allows you to eitheractivate the selected SFT into thesystem by picking Connect or toremove the selected SFT from thesystem by selecting disconnect.Default value is "Dscnct".

Number of SFTsRequired

• Set this to the number of SFTs usedin the particular feeder system.Normally a value of 1 is enteredhere.

SFT Raw Weight This represents the weight appliedto the SFT that is selected byaddress above. If the SFT weightexceeds the SFT range, an error willoccur.

Selected SFT Status A code is shown here that describesthe operational status of the SFTselected. Used by service only. Thisnumber is a decimal value of a hexnumber ( 2 byte) that describesvarious problems with the SFTbeing interrogated. There shouldbe some number in this location,zero is a type of failure.







SFT Type Code This identifies the gross scale rangeof the selected SFT. For a W300 andW600 machine, this variable willread 0006.

SFT Configuration • By pressing the ENT key, you willcause a "Poll" to result and thusidentify the connected SFTs. Toconnect an SFT, its address must bepreset to "0". SFT failure codes willshow here in the address locationthat is indicating the failure.

SFT Failure Codes "f" = SFT failure of its internalparts. A vibrating wire or othermalfunction has occurred. TheSFT is still communicating withthe controller. "t" = Timeout. The SFT is notcommunicating with thecontroller. The reasons are many. "?" = Incorrect response fromSFT. " - ' = No SFT at the locationindicated.

Frequencyoutput scaling

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

Frequency Name Equation for Output

Massflow Ouput Fo = (Massflow/FSS) * 10kHz

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

Fo = 5000 Hz.

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

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

Fo = 3000 Hz.

Beltloading Output Fo =

(Actual belt load/Belt Load Setpoint)*5Khz

ex: Fo = (2 lb/ft/5lb/ft )*5kHz = 2000 Hz.

Deviation fromSetpoint Output

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 CommandOutput

Fo =

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

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

Belt Speed Output Fo = Motor speed frequency.

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.

Note: The default value is 16,777,151 because the Low Battery shouldnot shutdown the feeders.



Weigh Belt Feeder Calibration-WBF

Introduction This section will help you to calibrate your weigh belt feeder. Please dothe tare calibration first.

Tarecalibration-WBF

To set the weigh belt feeder tare, please do the following.

Step Action

1 Empty the weigh belt feeder so that the weigh belt is clean

2 Run the feeder in Volumetric control with a Drive Commandof nearly 50%.

Adjust Massflow Setpoint and Belt Load Setpoint to adjust theDrive Command.

3 Stop the feeder.

4 Press the Tare Button, Key F3 on page Mcn.05. The feederwill run for a number of belt revolutions and then stop.

5 Record the value entered in the Belt Tare Weight location.

6 Plot this value as a point on your Tare or Zero Run Chart.

7 Tare is complete.

The tare runchart

It is useful to graph out the calibration values for tare. Here is a runchart for tare. Note that for a number of weeks, tare calibration wasquite constant. But on June 1, a problem developed. Rather than justrecalibrating, this chart tells us that something is wrong and needsrepair. A repair can be made to correct an otherwise hidden problem.

Please note that the starting tare value scaling is arbitrary but must befine enough to see what is happening to the calibration of the machine.

Spancalibration bytaking catchsamples-WBF

To do the this span calibration, the tare calibration must be completedfirst.

Step Action

1 Run the weigh belt feeder in VOL control and allow materialto flow onto the belt. Run so that the pile of material is stableand that belt loading is also stable.

2 Put the unit into GRAV control at some desired setpoint.

3 Start the feeder and let it stabilize its flowrate. Watch to seethat drive command is stable.

4 Take 5 consecutive 1 minute samples in five separatecontainers. Be sure each container is tared.

ex: 1.000 kg, 1.004 kg, 1.006 kg. 1.003 kg. 1.004 kg

5 Add the samples together and divide by 5.

1.000

1.004

1.006

1.003

1.004

= 5.017/5 = 1.0034 kg

6 Calculate your new span by the following formula: See pageMcn.05 for current span.

New Span =

Current Span *( Actual Samples/ Desired Samples)

Your setpoint was 60 Kg/hr so the desired setpoint in 1minute is 1 Kg. Current Span = 1.002

New Span = 1.002*(1.0034/1) = 1.005. Enter on page Mcn.05.

7 Take 5 more samples as in step 4 and recheck yourcalculations. If you have done it correctly, the span will notchange.

8 Record the new span value on the Span Run Chart.

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





Totalizermethod forspancalibration-WBF

You may elect to use the totalizer to set the feeder span rather thantaking catch samples. If so, please follow this procedure.

Step Action

1 Run the weigh belt feeder in VOL control and allow materialto flow onto the belt. Run so that the pile of material is stableand that belt loading is also stable. Stop the feeder.

2 Put the unit into GRAV control at some desired setpoint.

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:See page Mcn.05 for current span.

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 on page Mcn.05.

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

12 Record the new span value on the Span Run Chart.

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



Auto Cal Feature for WBF Software

IntroductionIn release ‘R’ of the K10S WBF software and K-Commander softwareRev. ‘L’, a new calibration function was added. You will set up andinitiate this function on the Belt Factor page Mcn.01.

Setting up thefeeder forautocalibration

Step Action1 Put material in the hopper. Put feeder in (GRAV) mode.2 Enter a setpoint close to your normal operating setpoint.

Run the feeder.3

Adjust the slide gate height to change the belt loading andbelt speed in order to meet the following conditions:

� The pile of material should be centered and not touchingthe side skirts.

� If you are running a pelletized material the belt speedshould be less than 60 ft/min.

� If you are running a powder, than the belt speed shouldbe less than 24 ft/min.

� The belt speed should be greater than 6 ft/min.

1. Record the actual belt loading when all of previousconditions have been met.

2. Calculate operational belt speed = normal setpoint / beltload

3. Calculate operational drive command =(operational beltspeed / max belt speed) * 100

For example:Belt load = 2 lb/ftMassflow Setpoint = 2400 lb/hr or 40 lb/minOp. Belt speed = (40 lb/min) / ( 2 lb/ft ) = 20 ft/minOp. Drive comm. = ( 20 / 60 ) * 100 = 33%




Auto Cal Feature for WBF Software, Continued

Calibrationusing the AutoCal feature

You can use this procedure to simplify feeder performance validation. Itis recommended that a tare be done first.

Step Action

1 Run the feeder in Vol control and allow material to flow ontothe belt. Run so that the pile of material is stable and that beltloading is also stable. Stop the feeder.

2 Setting Calibration Time

Go to the Belt Factors page Mcn.01 to set the time duration ofthe catch sample. The default setting is 60 seconds. Wesuggest that you set the Calibration Time to 300 seconds ifpossible. This allows for 5 minutes of sampling.

3 Setting Calibration Drive Command

Set the Calibration Drive Command to be equal to theoperational drive command, calculated in the previousprocedure.

4 Place a tared container under the feeder that can capture allof the material to be delivered in the Calibration Time.

Massflow Setpoint x Calibration Time = Weight

( 3000 lb / hr/3600 sec) x 300 seconds = 250 lb of product

5 Press F3 to commence the Calibrate Cycle process.

6 When the Calibrate Cycle is completed, look at theCalibration Correlation to verify that it is above 90%.





SampleCheck

Step Action

7 Quick Material Sample Check

When the calibration is complete, weigh the container andcompare it to the Material Fed in Calibration value. Calculatethe percentage error.

Cal.Matl.Fed value – actual material weight = Weight Difference.

The %error = (Weight Difference / Actual Mat. Weight) x 100

If the %error > 2% than you should contact a trainedmaintenance technician to identify the problem. You couldalso repeat the calibration procedure with a longerCalibration Time and recheck your %Error.

If the %error < 2% you can now put your feeder intooperation in Gravimetric mode.

!Remember, if you only took a single 60 second sample, you

may not have enough information regarding the accuracy of thefeeder. We do not recommend that you adjust SPAN with only one60 second sample. GO TO NEXT STEP!





SpanAdjustement

Step Action

8 If your calibration time was 300 seconds or longer you canuse your catch sample to change the span value if necessary.This is basically the same as using the totalizer methodexplained earlieer.

Calculate the new span setting from the following equation:

New Span, (Page Mcn.05) =

Current Span*( Container Weight/Material Fed in Calib)

ex: Current span = 1.004, Container weight =99 kgs, theMaterial Fed in Calib. reads 100 kgs.

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

Record the span value on your run chart.





The span runchart

It is useful to graph out the calibration values for span. Here is a runchart for span. Note that for a number of weeks, span calibration wasquite constant. Notice that unlike the tare run chart, no changes havebeen found outside a small band of variation.
