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: Sensor Front
2.4.1. Sensor front The TOF sensor measure the distance to object by emissing small pulses of IR-laser light and then measure the time for the light, reflected by an object, to return to the sensor. 2.4.1.1. SSC (Switching Signal Channel) For presence (or absence) detection of an object in front of the face of the sensor, the following settings are available: SSC1 or SSC2. -

Page 22: Filter Scaler
2.6.9. Filter Scaler This function can increase the immunity towards unstable targets and electromagnetic disturbances: Its value can be set from 1 to 255, the default factory setting is 1. The filter functions as a moving average. This means that a filter setting of 1 gives the maximum sensing frequency and a setting of 255 gives the minimum sensing frequency. -
