- Load Cell (Amplified & Not Amplified) calibration:
In load cell Mode, the max voltage needs to be calculated depending of the load cell type, the
mechanical integration into the customer application and the max resultant load put on the cell. To
help you please ask the WARNER Electric the load cell calculation spreadsheet.
1) Put the Load Cell to Min, press Min on the software:
Min is learnt automatically and displayed
2) Set Max manually (according to the load cell)
3) ) Click on ‘Write Current to XCtrl Partition P1P2P3’ button
to Save these parameters
- Filtering & inverting the input.
In case of noisy applications, the vibrations can cause the PID control to ‘compensate’ the noise. To
avoid this behavior, it’s possible to add an extra filtering which is going to reduce the noise processed
by the controller.
To activate this filter :
1) Click on the ‘XCTRL’ button in the main menu and on ‘Enable/Disable Advanced mode’. Two
tick box are appearing below the calibration menu. The first allow you to invert the input and the
second to filter it.
2) Tick the ‘Active filter’ box. A ‘Duration tab’ is appearing offering you the possibility to enter your
desired filtering time.
A ‘Invert Input’ button appears also, allowing you to invert the input if needed. In case of inversion,
the calibration of the input needs to be redone.
• Range Definition
To facilitate the value comprehension and the display, a logical range can be set-up, with selected its Unit, Min
and Max range Span and its Error threshold.
- Chose the working Unit (%, Kg, Nm …): any kinds of characters are
allowed. No conversion calculations are processed. This parameter is
only for display purpose to facilitate the comprehension of the input.
- Working Range: this is the “logical range” in which the controller will
process all its data. This has the advantage to facilitate the human
interfacing, with having both human and controller talks the same
“language”, actually the same unit. Set-up is according to your
application data.
- Error threshold: these Min and Max values are defining the error
threshold out of which the controller is emitting an Error signal. Once
the Sensor/load cell measured value is below or over these thresholds,
the XCTRL is triggering the Error Sense signals (ErrS1 or ErrS2). ErrS1
is linked to the Cell/Dancer 1 Input when ErrS2 is linked to the Cell/
Dancer 2 Input.
