YM:Schenck ShakeControl VVC29150

1 Important general information

At the end of 2017 the old FRS 0052 controller will be replaced by the new VVC 29150 controller.

As soon as the replacement was done all Vibro Feeders will be equipped with the new Vibro controller.

By taking a closer look at the picture you will see that there are no longer potentiometers like they used to be on the FRS 0052.

As we all know by changing the setting of the potentiometer the oscillation amplitude of the exciter was modified – modifying the oscillation amplitude from now on can only be done via EasyServe anymore.

The parameters of the VVC 29150 can be modified at chapter “42 Virbo Controller VVC” via EasyServe.

The set of parameters consists of 14 settings like P42.07 Gain (Index) 1 and P42.08 Gain (Index) 2 and is saved together with the settings of the dosing unit.

According to Schenck it should not be necessary to modify the default parameters of the VVC 29150, but since we don’t have much experience with the new vibro controller yet we cannot be not sure if it’s going to be like that.

Apart from this, it's important to know, that the new Vibro Feeder also comes with a new vibration sensor named VME 29150-2GD.

This sensor measures the acceleration instead of the velocity which was done by the previous sensor VRS 20300(-1D3G).

Please make sure that you have at least EasyServe v28 installed on your notebook and that Schenck Tersus has the firmware version vlw20172_005.

Disocont® controllers need no firmware update!

9.2 Firmwareupdate of Disocont® Controller

No Firmwareupdate required

9.3 Commissioning

The commissioning consists of four major steps:

1. Check actual feeding rate I with current Bypass value
2. Perform Calibration program “Vol. Discharge Adaption”
3. Adjust mechanical setup of the Vibro Feeder or modify P42.07 of VVC 29150 if determined Bypass value is too high – recommended range 10-12mA for dosings with low flow rate and 14mA for dosings with high flow rate
4. Run Calibration programs “Linearization P1, P2, P3 and P4”

9.3.1 Check actual feeding rate with VVC 29150

1. Open EasyServe v28 (or higher) and connect to the dosing unit
   
2. Unlock EasyServe user interface
   
3. Set P12.21 Bypass Adaption if not already configured to 1,000 and deactivate P12.19 Controller Adaptation
   
4. Open "Scale Operation 1" and start Keyboard Mode
   
5. Enable Volumetric Mode and start the dosing unit
   
6. Set P to Maximum Flow Rate
   

9.3.2 Calibration program "Vol. Discharge Adaption"

1. View "Scale Operation 1"
   
2. Set "Gravimetric Mode"
   
3. Start Dosing Unit
   
4. Set P to Maximum Flow Rate
   
5. Start Calibration Program "Vol. Discharge Adaption"
   
6. Wait until Deviation is around zero and for control magnitude and set/act value to stabilize on display
   
7. Press "Apply" - value will be taken over into Parameter P 12.03 Bypass
   

9.3.3 Adjust mechanical setup of the Vibro Feeder or modify P42.07 of VVC 29150 if determined Bypass value is too high

If for whatever reason the determined Bypass value after the Volumetric Discharge Adaption is outside of the recommended range of 10-12mA for dosings with low flow rate and 14mA for dosings with high flow rate, there are two possibilities to change that:

1. Change mechanical setup of the Vibro feeder
2. Adjust P42.07 Gain (Index) 1 of the VVC 29150: This value defines with which factor the system amplifies the actual value of the vibration amplitude. In other words, this value affects the maximum possible vibration amplitude – the higher the value, the higher the amplitude.

Note: This parameter only works in combination with the sensor VRS 20300 and only applies to the conveyor speed range 1.

9.3.4 Run Calibration programs "Linearization P1, P2, P3 and P4"

Note: The vibro feeder discharge characteristic is non-linear. To improve the assignment of set points to actual values and the control quality in gravimetric mode, linearization has to be performed.
Recommended values are: P1 = 5%, P2 = 10%, P3 = 30%, P4 = 60% of the Maximum Flow Rate

1. View "Scale Operation 1" and start Keyboard Mode
   
2. Set "Gravimetric Mode" and start Dosing Unit
   
3. Enter feed rates P1 to P4 at P
   
4. Open Calibration Programs
   
5. Start Program Linearization P1
   
6. Wait until deviation value is around zero
   
7. Accept result by pressing apply
   
8. Call up Linearization Program P2 and repeat previous steps (don’t forget to change P to P2)
   
9. Call up Linearization Program P3 and repeat previous steps (don’t forget to change P to P3)
   
10. Call up Linearization Program P4 and repeat previous steps (don’t forget to change P to P4)
    
11. Set Parameter P 13.01 Linearization to YES
    
12. Set setpoints P1 to P4 once more and check if actual feeding rate I reaches the setpoint P more smoothly
    

Template:Notice bms Finally please make sure that P12.19 Controller Adaptation is set to YES and the Dosing Unit is ready for a function test.

10.2 Firmwareupdate of Schenck Tersus Controller

Template:Notice bms#Start EasyServe v28

1. Goto Tools / Flash / Flash SPI
2. Choose your type of communication (Ethernet might be more convenient)
3. Enter IP address
4. Select firmware
5. Follow instructions according to download manager

After the firmware download has been successfully finished you will recognize that the IP address as well as the name has been set to default values.

1. Goto Connection / Ethernet (Scanner) - you will see the previously updated dosing unit shown as red
2. Select the controller and hit the Configure button
3. Type in the former IP address, subnetmask and gateway and click on Apply
4. After that press the Configure button one more time and carry out the same procedure for the name of the dosing unit. Setting up name and IP address in one step somehow didn’t work during my test, but maybe you are luckier.

In case the firmware download for whatever reason fails and you cannot reach the dosing unit via Ethernet anymore you need to set up a serial connection to the unit via terminal X102:

Contact on X102 (VVC 29150)	RS232 serial port on the PC
1 (GND)	5 (GND)
2 (Tx)	2 (Rx)
3 (Rx)	3 (Tx)

After that you should be able to carry out the firmware download one more time and hopefully finish it without any troubles.

The commissioning consists of four major steps:

1. Check actual feeding rate I with current Bypass value
2. Perform Calibration program “Vol. Discharge Adaption”
3. Adjust mechanical setup of the Vibro Feeder or modify P42.07 of VVC 29150 if determined Bypass value is too high – recommended range 10-12mA for dosings with low flow rate and 14mA for dosings with high flow rate
4. Run Calibration programs “Linearization P1, P2, P3 and P4”

10.3.1 Check actual feeding rate with VVC 29150

1. Open EasyServe v28 (or higher) and connect to the dosing unit
   
2. Unlock EasyServe user interface

10.3.3 Adjust mechanical setup of the Vibro Feeder or modify VVC 29150 parametrization if determined Bypass value is too high

If for whatever reason the determined Bypass value after the Volumetric Discharge Adaption is outside of the recommended range (10-12mA for dosings with low flow rate and 14mA for dosings with high flow rate) there are two possibilities to change that:

1. Change mechanical setup of the Vibro feeder
2. Adjust P42.07 Gain (Index) 1 or P42.09 Oscillation Amplitude MESM of the VVC 29150:

Note: P42.07 only works in combination with sensor VRS 20300 and P42.09 only with VME 29150.
P42.07 defines with which factor the system amplifies the actual value of the vibration amplitude. In other words, this value affects the maximum possible vibration amplitude – the higher the value, the higer the amplitude.
P42.09 specifies the maximum vibration amplitude. By default this parameter is set to 1.5mm – adjustment range according to Schenck: 0.8 to 2.0mm

10.3.4 Run Calibration programs "Linearization P1, P2, P3 and P4"

Note: The vibro feeder discharge characteristic is non-linear. To improve the assignment of set points to actual values and the control quality in gravimetric mode, linearization has to be performed.
Recommended values are: P1 = 5%, P2 = 10%, P3 = 30%, P4 = 60% of the Maximum Flow Rate

8. Call up Linearization Program P2 and repeat previous steps (don’t forget to change P to P2)
   
9. Call up Linearization Program P3 and repeat previous steps (don’t forget to change P to P3)
   
10. Call up Linearization Program P4 and repeat previous steps (don’t forget to change P to P4)
    
11. Set Parameter P 13.01 Linearization to YES
    
12. Set setpoints P1 to P4 once more and check if actual feeding rate I reaches the setpoint P more smoothly
    

Template:Notice bms Finally please make sure that P12.19 Controller Adaptation is set to YES and the Dosing Unit is ready for a function test.
