    Functional Principle, Technical Data Proper Environment - Protection class: IP 65 - Operating temperature: -10 °C ... +55 °C - Storage temperature: -10 °C ... +85 °C - Humidity: 20 - 80 % relative humidity (non-condensing) - Ambient pressure: Atmospheric pressure The sensor is stable and can be used in a wide temperature range.

  • Page 10: Functions

    Functional Principle, Technical Data The transformed values (colors), are stored in the sensor and continuously compared to the current color. When the colors are all within the entered tolerance range, a recognition signal is sent to the digital switching outputs and the keyboard indicators. This process allows storage of multiple colors in various color spaces. In the same manner, the color values and the recognized color are output as data protocol via the available interfaces as required.

    Assembly The frequently used and standardized M12 sockets allow use of standard commercial cables to match the specific, special requirements of the specific operating environment. For example, cables are available, which are oil-resistant or suitable for use with drag chains. The input and output signals from the sensor as well as the power supply and communication connections are accessible using standardized M12 connectors (male and female).

    The switching state zero is not used to ensure reliable test performance in the face of a discontinuity. The switching state all switched is recommended as the standard error output. Use shielded cable with a length < 30 m. Micro-Epsilon recommends use of CAB-M12-8P-Bu-ge cable, available as an option, see Chap. 4.4.2 Ethernet (ETH)

  • Page 28: Optical Fiber, Sensor Cable

    Assembly Optical Fiber, Sensor Cable Plug the optical fiber into the optical fiber connector on sensor. Fig. 13 Optical fiber connector on sensor Fig. 14 Installation of optical fiber cable The coding for the optical fiber connection (FA) is located on the illumination LED. Keep the end surfaces of the optical fiber cable free of dust, avoid any damage or soiling, e.g.
  • Page 29 Assembly Please observe the permissible minimum bending radius for the optical fiber used. Failure to observe the minimum bending radius (depending on the type of optical fiber used) leads to breakage of the optical fiber. Since the optical fiber cable consists of multiple fibers, breakage of any of the optical fibers leads to a reduc- tion in the illumination intensity and, in the case of signal cables, to a decrease in the measuring signal.

  • Page 30: Commissioning

    Operation Operation Commissioning Connect the sensor to the optical fiber cable, see Chap. 4.5. Fig. 15 Overall view of colorSENSOR CFO with optical fiber Connect the sensor to a power supply, see Chap. 4.4.1. Switch on the power supply. After switching on the sensor, the green LED flashes and the red LED illuminates continuously as long as the sensor is booting, see Fig.
  • Page 31 Operation The sensor is in the operating mode when only the green Power LED is illuminated, see Fig. Fig. 17 Green LED illuminated continuously (operating mode reached) Then, depending on whether the key lock is active and colors are detected, the corresponding LEDs illumi- nate or the set output circuit for color is not detected.

  • Page 32: Membrane Keys

    Operation Membrane Keys The colorSENSOR CFO can be configured using the network interface, the serial interface and the keyboard integrated into the housing. Due to the functional scope and the accessibility of the sensors, only the most important settings are accessible via the keyboard. For special applications it may therefore be necessary to use the network or serial interface to make initial settings.

  • Page 42: Teaching Colors

    Operation 5.4.2.1 Teaching Colors One or more colors can be learned for each recognition group, see Chap. 5.4.5.3. The recognition groups are differentiated according to their output coding. The 1-out-of-N codes are easily accessible via the key- board (only one of the output lines is active). Although the subsequent binary codes can be scrolled though individually, the large number of possible combinations (up to 256 for the CFO200) makes it more convenient to use an auxiliary program or the HTTP-API for this purpose.

  • Page 49: In0 Switching Input Function Assignment

    Operation 5.4.5.1 IN0 Switching Input Function Assignment Using the keyboard it is possible to assign switching input IN0 to GATE for triggered color evaluation or to TEACH for triggered color teaching. If neither of the two functions is selected, the LEDs flash slowly (100/1900 ms).

    Operation 5.4.5.2 Hold Time Extending the hold time for a recognition result beyond the actual duration of color matching is practical when the actuators controlled by the color sensor require a certain minimum hold time for the switching level. The hold time can be set to one of three different stages in the option menu. Stage Hold Time Description of LED display...

  • Page 52: Multiple Teach Mode

    Operation 5.4.5.3 Multiple Teach Mode The multiple teach mode allows keyboard selection of whether each recognition group may contain only the last color saved, or whether it can be assigned a number of colors. This setting has no influence on the behavior of the other user interfaces (HTTP-API or own software).
