The out sensor used for the vorlaufwagen c … The out sensor used for the vorlaufwagen cannot be a standard reed switch because the cylinder that drives this output is a telescoping version. It is impossible to detect the out position. Therefore, a sensor is fitted that must be programmed to set a high output when it detects the full range has been reached The sensor is a [https://www.pepperl-fuchs.com/global/en/classid_53.htm?view=productdetails&prodid=42559#overview Pepperl+Fuchs VDM28-8-L] Datasheet can be downloaded [https://files.pepperl-fuchs.com/webcat/navi/productInfo/45/452859n.pdf?v=20220926110229 here] '''Function''' The distance measurement device contains one transmitter and one receiver incorporated into a single housing. The transmitter light is reflected back to the receiver from a target. The sensor determines the distance to the target and triggers a switching function or supplies the relevant measured value for processing. '''Assembly instructions''' The sensor can be mounted by means of through holes or by using a mounting bracket or mounting clamp Ensure that the surface is level in order to prevent the housing from becoming distorted when the fittings are tightened. It is advisable to secure the nuts and screws using spring washers in order to prevent the sensor from being incorrectly adjusted. '''Connection''' Connect the device in accordance with the connection diagram in the datasheet. '''Adjustment''' The green LED lights up when the operating voltage is switched on. Adjust the sensor so that the laser point is on the gripper bodyso that the laser point is on the gripper body +

...Note! The difference in the taught-in distance measured values for the switching thresholds A and B must be greater than the switching hysteresis set in the sensor. On delivery, the switching hysteresis is 15 mm. If the difference in the taught-in measured values is the same as or smaller than the set switching hysteresis, the sensor will visually signal an unsuccessful Teach-In. The last distance measured value that was taught in will not be adopted by the sensor. Select a new distance measured value for switching threshold A or B with a greater difference between the switching thresholds. Teach in this distance measured value on the sensor again.
