Page 8: Process Data
Access to internal parameters allows the user to see how the sensor is performing, for example by reading the internal temperature. Event Data allows the user to get diagnostic information such as an error, an alarm, a warning or a communication problem. -
Page 9: Output Parameters
2.4. Output Parameters Seven sensing functions and 4 application functions can be selected. These values can be independently adjusted and used as source for the Switching Output 1 or 2; in addition to those, an external input can be selected for SO2. After selecting one of these sources, it is possible to configure the output of the sensor with a SCTL55 or an IO-Link master, following the seven steps shown in the Switching Output setup below. -
Page 10: Sensor Front
2.4.1. Sensor front The Background Suppression sensor emits light towards a target and measure the position of the light reflected from the target. If the measured position value is equal to or less than a predefined position for the target, the sensor changes the output state. The measured sensing distance is almost independent of the target colour 2.4.1.1. - Page 11 Two point mode The switching information changes when the distance measured passes the threshold defined in setpoint SP1. This change occurs only with decreasing distance measured. The switching information also changes when the distance measured passes the threshold defined in setpoint SP2.

Page 12: Hysteresis Settings
2.4.1.3. Hysteresis Settings The hysteresis can be set automatically or manually for SSC1 and manually only for SSC2. The hysteresis is set in mm for SP1 and SP2. Note: When trimmer is selected, the default hysteresis is Automatic. Automatic hysteresis: Automatic hysteresis will guarantee stable operation for most applications. - Page 13 Symbol Truth table 2-input AND Gate Boolean Expression Q = A.B Read as A AND B gives Q Symbol Truth table 2-input OR Gate Boolean Expression Q = A + B Read as A OR B gives Q Symbol Truth table 2-input XOR Gate Boolean Expression Q = A + B A OR B but NOT BOTH gives Q...

Page 20: Divider Function
2.4.7.3. Divider function This function allows e.g. the user to set up a number of counts to be performed before changing the output. By default, this value is set to 1 and each activation causes the output to change. When the value is set to a higher value e.g. 10 then the sensor will give output every 10th detection, the sensor will count at the trailing edge of the object. -
Page 21: Object And Gap Monitoring
2.4.7.4. Object and Gap Monitoring This function is designed to monitor that the length of an objects and the gap between the following object on a conveyor belt are within certain limits. The stand alone sensor gives a signal if the size of the object is too small, the objects overlap each other or if the gap between two objects are too small for the following processes. - Page 22 b) Enter the maximum time the Gap will be present in the menu “Object and Gap monitor” -> “Gap maximum time” between 10 … 60 000 ms (default value is 500) ms, e.g. 130 ms. As a help the gap time can be read from the “Object and Gap monitor” -> “Gap time”.

Page 33: Wiring Diagrams
NOTE! The temperature measured by the sensor will always be higher than the ambient temperature, due to internal heating. The difference between ambient temperature and internal temperature is influenced by how the sensor is installed in the application. If the sensor is installed in a metal bracket the difference will be lower than if the sensor is mounted in a plastic one. -
