Fig. 18 Sensor connection on the controller Fig. 19 Mounting of sensor (optical fiber) The coding on the sensor connector (CFS or FA) is on the side of the illumination LED. Keep the end surfaces of the sensor free of dust, avoid any damage or soiling, e.g.
  • Page 38 Installation and Assembly Please observe the permissible minimum bending radius of the integrated optical fiber. Failure to observe the minimum bending radius (depending on the sensor model) leads to breakage of the integrated optical fiber. As the sensor (optical fiber) consists of a glass fiber bundle with several individual fibers, a break in the illu- mination fibers causes a drop in the illumination intensity, and a reduced measurement signal of the signal fi- bers.

Automatic modulation is required after replacing the sensor (optical fiber) with changed measurement ar- rangement or when the measurement environment has changed. Fig. 39 Automatic modulation The automatic modulation determines a suitable combination of internal controller parameters for the current optical situation.
  • Page 89 Operation Since a combination of control parameters such as amplification, averaging, receive brightness and LED brightness is taken during automatic modulation, one needs a control variable. This is the measurement frequency at which the data is to be output via the digital I/Os. Automatic modu- Effective measurement Starts automatic modulation of the controller.

    Operation 5.6.3.4 White Reference Go to Settings > Detection profile > White reference. Since the sensor (optical fiber) can have an influence on the color accuracy of the measurement, we rec- ommend a white balance after replacing a sensor (fiber optics) if the measuring arrangement or measuring environment has changed.
  • Page 91 Operation Performing White Balance We recommend performing a white balance after replacing a sensor (fiber optics) or if the measurement environment has changed. Switch to Settings > Detection profile > White reference. Recommendation: Position the white standard, see optional accessory, see A 1, at the permissible measurement distance to the sensor.

  • Page 94: Hold Time

    Operation 5.6.4.2 Hold Time Go to the menu Settings > Color group > Hold time. The hold time determines how long the output configuration of the detected color is held. The hold time must not be negative. In high-speed production lines, the measuring object is detected by the sensor for just a few µs. With a measurement frequency of 30,000 Hz, up to 7,500 parts/sec (up to 15,000 parts/s with synchronous opera- tion) can be reliably detected without synchronous operation and signaled at the switching outputs.
