    5) 1=transient protection, 2=polarity reversal protection, 3= short-circuit protection for transistor output Remarks  Function Attention! characteristics: The OPSL 775 edge detector It is imperative that the safety notices in section 8 are observed is an optoelectronic sensor for the contactless detection of object edges.
  • Page 3 It is imperative that the safety notices in section 8 are observed It is possible with the OPSL 775 to detect edges being conveyed within a range of 5 to 150 mm, as measured from the underside of the device. The sensitivity range is dependent on the working distance. By focussing the laser beam to a distance of 100mm, detection of the smallest possible edge height of 0.1mm is only possible within the focus range of 100mm ±...

    Calibration of working distance (CAL) Sensitivity (Sens) Fig. 2: OPSL 775 - operational controls Potentiometer for output pulse width( This potentiometer allows the output pulse width to be modified in stages, whereby turning to the left / right effects an increase / decrease of the output pulse width (left limit stop: Maximum pulse width = 1023ms or right limit stop: Minimum pulse width = 1ms).

  • Page 5: Installation / Alignment

    In order that optimum functioning of the device can be guaranteed, the following points must be observed during installation: 1. The OPSL 775 must be installed in such a manner that vibrations are completely eliminated, otherwise there is a risk of counting errors occurring.
  • Page 6 The correct direction of overlap is stamped onto the front side of the device. The OPSL 775 only counts those edges which are pointing in the conveying direction. Thus, in the case of an uninterrupted overlap flow, the last copy is counted only once as the "falling edge" is not detected.
  • Page 7 Calibration is concluded and it should now be possible to count the edges in the overlap flow with a constant working distance. Under certain circumstances, the calibration procedure may have to be repeated. In the event that no edges can be detected, please refer to the procedure for setting the OPSL 775 in section 5. General There are three possibilities for optimum adaptation of the device for the specified counting tasks: 1.
  • Page 8 It must be ensured that the output pulse width is not greater than the period following the edge! We recommend using the dynamic pulse adaptation DPA wherever possible.
