2 Introduction SCATEC-2 has the same key feature as all the other sensors from the SCATEC family: The capability of non-contact detection of object edges. SCATEC is the sensor of choice when it comes to detect flat objects conveyed in an overlapping stream or individually. The sensors in the SCATEC family were developed and highly optimized particularly with regard to the specific demands of non-contact counting of overlapping paper sheets and newspapers.

Overlap: a Distance between two successive edges, measured along the conveying plane. (Also referred to as the object spacing.) Edge thickness: k Thickness of the copy at the point where the edge is to be detected. Front edge The edge of an object facing the laser beam. Front edges are detected by the sensor. Tail edge The edge of an object facing away from the laser beam. Tail edges are not detected by the sensor unless they are pointing upwards.
7 7.1 Installation Electrical connection Make the electrical connections as specified in Sections 10.2 Electrical data and 10.3 Pin assignement. 7.2 Mounting (1) Mount the sensor at the nominal working distance h (+/-3 mm) with the front window parallel to the conveying plane. (2) Adjust the sensor so that the laser beam is aimed towards the edges to be counted. When mounted correctly, the overlap of the copies is facing in the same direction as indicated in the alignment aid.
.3 Beam blocker Uncontrolled reflections of the laser beam can cause malfunctioning of the sensor or disturb people. Therefore, a beam blocker should be fitted whenever possible to block the beam when there is no target present. A flat surface (at least approx. 25x25 mm) made of a matte, non-reflecting material is recommended as the beam blocker. The beam blocker must be mounted parallel to the sensor. The yellow edge indicator LED must not light when the laser beam strikes the beam blocker. 7.

A helpful rule of thumb is: Output pulse length p in milliseconds must be shorter than 1.2 million divided by the production rate given in copies per hour The theoretical maximum production rate where output pulses follow each other without any gap in between is 3 times higher than the recommended value given by the rule of thumb. Exceeding the recommended value of the production rate increases the risk of missing edges due to irregular intervals between copies.
The following diagram shows a comparison of the pulse sequences for active and inactive false pulse suppression with an identical lap stream. Running direction on yellow edge-LED off high p low a t output pulse (pulse period: p) Scatec inactive Scatec active dead time (duration: t = 18% of the average overlap a) high output pulse (pulse period: p) low Scatec inactive Scatec active dead time (duration: t = 0) time Manual SCATEC-2 Version 2011-05 9.3 19 www.baumer.
9.5 Signal sequence Every output pulse is preceeded by a flash of the yellow edge-LED, however, not every flash of the yellow edge-LED is followed by an output pulse! The yellow edge-LED lights as long as an edge is located in the beam. Whether this edge actually results in an output pulse or not depends on the current settings. The pulse could still be suppressed due to restrictions imposed by the dead-time or pulse length (see section 6).

12 Maintenance The SCATEC-2 requires no maintenance apart from keeping the front windows clean. Dust or fingerprints can impair the sensor function. It is normally sufficient to wipe the windows dry with a clean (!), soft cloth. Alcohol may be used for heavy soiling. The cover of the DIP switch must be mounted, otherwise dust might intrude. Dust inside the housing can cause the sensor to malfunction.
Fault 2 Scatec counts more copies than actually pass the sensor Manual SCATEC-2 Version 2011-05 Possible causes Corrective actions (see manual section x.x) a) Apart from the edges, there are other patches on the copies which cause false pulses. Prevent critical patches on the copies. b) Laser beam on beam blocker causes false pulses. Adjust beam blocker correctly (yellow edge LED must never light when the laser beam strikes the beam blocker).
