O3M151 3D Smart Sensor Object Detection

2.3 Operating check

With an optical system, detection faults can occur in case of poor visibility (e�g� under very dense fog, a great deal of dust, very heavy snowfall, etc�)� The O3M151 Smart Sensor is equipped with sensory fault detection in the system and generates a message when faults occur�

● the "Blockage Detection" function actively detects relevant soiling, condensation on or icing-up of the sensor;

(This function is not yet available with the SW Version OD 2�2�4 and OD 2�2�5� It will be possible to activate this function later in a firmware update�)

● The "Diffuse Scene" function actively detects diffuse faults, such as dense fog or clouds of dust in the sensor area�

Internal diagnosis of the hardware for faults → Operating instructions

● Application-specific solutions can result simply and especially conveniently with a controller (e�g�

CR040X) or display (e�g CR108X) based on the functional output�

There are special CODESYS libraries for receiving and interpreting the CAN signals of the O3M151

Smart Sensor� In addition, various application examples on a CODESYS basis are also available�
