This laser belongs to the Class 2 laser standard specified by the IEC 60825-1 / 2007. Avoid looking directly into the beam for long periods. Brief irradiation of the eye (0.25 sec) that can occur during an accidental glance is not regarded to be dangerous. However, the laser should not be aimed deliberately at people. The laser beam should also be blocked at the end of its intended path. Scatec-2 complies with the following safety standards: Complies with 21CFR 1040.10 and 1040.11 except for deviations pursuant to laser notice No.50, dated June 24, 2007 Manual SCATEC-2 Version 2011-05 4 www.baumer.com Baumer Electric AG Frauenfeld, Switzerland 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. Therefore the printing industry will be the ideal area of application for the SCATEC. Generally speaking a SCATEC sensor reacts to an edge facing the sensor’s laser beam. If the laser beam strikes such an edge, SCATEC responds with an electrical output pulse of fixed duration. However, built-in software allows the sensor among other things to suppress the reaction to certain edges which were identified by the sensor as “false edges”. Therefore, SCATEC-2 makes it possible to count newspapers to the highest degree of accuracy even at high conveyor speed. Within the SCATEC family, the SCATEC-2 is characterized by the following properties: (For details see specifications of the individual Scatec-2 types.) • • • • • • counts edges from a thickness of 0.2 mm and greater optimum working distance: 40 mm or 100 mm intelligent false pulse suppression parameter setting by means of DIP-switches counting rate up to 600,000 copies per hour with interface for remote control and data analysis Manual SCATEC-2 Version 2011-05 3 5 www.baumer.com Baumer Electric AG Frauenfeld, Switzerland Principle of operation Described simply, the SCATEC-2 consists of a laser light source and two photodetectors. The beam is aimed diagonally at the objects to be detected. Photodetector R is located close to the laser light source and photodetector V a little further away. The sensor measures the ratio between signal v (light scattered forward) and signal r (light scattered backward). The ratio v/r differs widely depending whether the beam strikes on a flat surface or on an edge. When an edge moves into the laser beam, the direct line of sight from detector V to the point of contact of the laser is obstructed, which reduces signal v, and the edge also increases the backward scattering, causing signal r to increase. Both effects cause ratio v/r to become substantially smaller than with a flat surface. If ratio v/r falls below a specific level, the sensor interprets this as an edge. This principle of operation clearly demonstrates that: • • Manual SCATEC-2 Version 2011-05 The orientation of the object to the beam is significant. An edge facing towards the beam creates a small ratio v/r, in contrast to an edge facing away from the beam. Edge detection is independent of the color, as only the ratio of the light intensities and not the absolute value is used for detection. 6 www.baumer.com Baumer Electric AG Frauenfeld, Switzerland 4 Part identification Edge-LED (yellow) DIP-switch cover with screw Power-LED (green) Alignment aid Front window Sensor plug DIP-switches Lower edge of sensor O-ring Connector : .../S42 DIP-switches Manual SCATEC-2 Version 2011-05 5 .../S14 7 www.baumer.com Baumer Electric AG Frauenfeld, Switzerland Terms and definitions For reference, the terms defined in this section are used throughout the manual.

Working plane The edge lies on the working plane. With thick overlapping copies, the working plane is slightly higher than the top of the conveying plane on which the copies are transported. Distance d is measured vertically to the lower edge of the sensor. Working distance: d Distance between the lower edge of the sensor and the working plane. Manual SCATEC-2 Version 2011-05 8 www.baumer.com Baumer Electric AG Frauenfeld, Switzerland 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. Running direction The preferred running direction (front edges leading) is indicated. The opposite direction is also permitted by the SCATEC-2. Dead time t The sensor responds to an edge with an output pulse with length p. The dead time begins when the pulse is issued. The sensor can t only issue the next pulse after p both the dead time t and the output pulse p have expired. This means: an edge detected by the beam while still either the dead time t or the the output pulse p is on does not initiate an output Output pulse Dead time pulse. False pulse Output pulse generated by an edge which should not be counted. Manual SCATEC-2 Version 2011-05 6 9 www.baumer.com Baumer Electric AG Frauenfeld, Switzerland Signal sequence The yellow edge indicator LED lights as long as an edge is located in the beam. The output pulse is issued at the end of the edge. The dead time begins when the output pulse is issued. During the dead time and when issuing the pulse, the SCATEC-2 is inactive, i.e. an edge ending during the dead time or the pulse issue of the previous edge will not initiate an output pulse. Therefore, the next output pulse can only be issued after the dead time has expired and the output pulse has been issued.

(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. Note: the laser beam is focused into a line which must be aligned in parallel to the edge to be detected! (3) Block the laser beam after the objects whenever possible. (4) Keep the window clean (remove any fingerprints after mounting!). (5) A direct line of sight from the laser impact point to the entire front window must be ensured.

If an edge faces away from the beam, it is not detected. Tail edges are therefore not counted unless they face upwards. Running direction The SCATEC-2 permits both running directions. The edges facing the laser beam (front edges) are detected by the sensor regardless of the running direction.

Manual SCATEC-2 Version 2011-05 12 www.baumer.com Baumer Electric AG Frauenfeld, Switzerland 7.3 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. 7.4 Cleaning the front window Fingerprints, dust and other forms of dirt on the front window can impair the function of the sensor. There is a high risk of accidentially leaving fingerprints on the windows when mounting the sensor. Make sure that after the mounting the front windows are cleaned! It is normally sufficient to wipe the glass pane dry with a clean (!), soft cloth. Alcohol may be used for heavier soiling. 7.5 Checklist for correct mounting When the SCATEC-2 is mounted correctly: • • • • • • • the green power LED lights as long as the electrical supply is connected the product overlap faces in the same direction as indicated on the sensor label the laser beam is focused on the conveying plane into a line about 2 (3) mm long the laser line focus must be aligned in parallel to the edges to be detected the yellow edge indicator LED does not light when the laser beam strikes the beam blocker the yellow edge indicator LED lights as long as an edge is located in the beam the front windows are clean Manual SCATEC-2 Version 2011-05 8 13 www.baumer.com Baumer Electric AG Frauenfeld, Switzerland Adjustments With the SCATEC-2, the following parameters and operating modes can be adjusted: • Output pulse length • False pulse suppression • Sensitivity The parameters can be adjusted in two ways: via the interface or using DIP switches. Parameter setting through the interface allows continuous choice of the parameters, whereas a selection is made from a defined set when the parameters are set with the DIP switches. Parameter setting through the interface using a computer is described in the user manual for the software package ScaDiag. Note: • The sensor is only in DIP switch mode when the power LED lights green. If the power LED lights yellow instead of green, the parameters of the sensor have been set through the interface. In this case, the DIP switches are inactive on the sensor and their settings are irrelevant. The sensor can be reset to DIP switch mode, in which the parameters are defined by the DIP switches, in two ways. a) Through the interface (see user manual for the software package ScaDiag). b) By setting the DIP switches in the following sequence: 1. 2. 3. 4. • Set all switches to OFF (at least one must have been ON previously) Set all switches to ON within 16 seconds Set all switches back to OFF within 16 seconds The power LED should then light green after a brief delay. The parameters of the sensor can then be adjusted with the DIP switches To prevent the loss of the DIP switch cover screw, do not fully remove it from the cover. The screw is retained by the cover.

On the other hand, the length of the output pulse limits the maximum counting rate. Because output pulses must not overlap, the interval between edges must be at least as long as one output pulse length. If the interval is shorter, then this edge will be suppressed meaning that the edge will not initiate an output pulse. The following figure illustrates how every other edge is suppressed because of a too long of an output pulse length. Scatec-2 a a on amber edge-LED off high output pulse pulse length p < interval a p low high p low output pulse pulse length p > interval a some edges are suppressed! time Manual SCATEC-2 Version 2011-05 16 www.baumer.com Baumer Electric AG Frauenfeld, Switzerland 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 table lists the recommended maximum production rate for some values of the output pulse length. set output pulse length recommended maximum production rate [milliseconds] 1 2 5 10 15 20 [copies/hour] 1,200,000 600,000 240,000 120,000 80,000 60,000 If suddenly the Scatec starts to miss copies while the production rate is run up, the reason very often is too short an output pulse length for the actual production rate in combination with fluctuations of the interval between copies. Manual SCATEC-2 Version 2011-05 9.2 17 www.baumer.com Baumer Electric AG Frauenfeld, Switzerland False pulse suppression It is generally recommended that the SCATEC-2 should be operated with the false pulse suppression feature active. In this way, multiple pulses caused by thicker copies (newspapers, folded cardboard boxes etc.) or by a small crease at the edge can be suppressed. The false pulse suppression feature ensures that no further pulses can be issued when an output pulse is active and during the dead time. Activating the false pulse suppression feature causes the sensor to automatically initiate a dead time when each pulse is issued, whose duration is 18% of the average overlap spacing. If an output pulse is followed by another in less than about 1/6 of the current average overlap spacing time, this pulse is suppressed, as it lies within the dead time of the preceding pulse. The average overlap spacing time is constantly recalculated automatically by the SCATEC-2. This ensures that the dead time is adjusted if the conveying speed changes. In certain cases, one edge may be suppressed if the conveying speed is very quickly accelerated, whereas one false impulse may not be suppressed during very fast braking. However, gaps in the overlapping stream caused when individual copies are removed or when the overlapping stream is briefly diverted have no effect. The false pulse suppression feature has no effect on the maximum counting rate as the dead time is shortened as the counting frequency rises and can even become shorter than the output pulse length. This occurs when the average copy spacing time becomes less than 6 times of the output pulse length. Ideally, the sensor would not issue further pulses after a valid output pulse for a specific length, as the typical distance between two edges is often known regardless of the speed. Anything between these would be false pulses. However, to allow the sensor to suppress pulses for a specific length and not for a defined time, it must be synchronized to the conveying speed. This is possible with the Scatec-10 and Scatec-15. Always switch on false pulse suppression unless the overlap spacing is highly unregular. Individual copies may be ignored during abrupt acceleration or if the overlap spacing suddenly becomes smaller. Manual SCATEC-2 Version 2011-05 18 www.baumer.com Baumer Electric AG Frauenfeld, Switzerland 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.com Baumer Electric AG Frauenfeld, Switzerland Sensitivity Because the Scatec cannot discern between a front edge (which the customer wishes to detect) and a spot on the object similar to an edge (e.g. crests or creases in the paper, creases in a carton etc), the sensitivity of the sensor should be adjusted to the edge thickness to be detected. This means that the sensor should be set to a sensitivity at which it detects all leading edges without being sensitive enough to react to edge-like spots on the object thinner than the actual edge thickness. It is possible to choose between two different sensitivity levels with DIP switch 4. A diagram of the sensitivity in relation to the working distance and transportation speed is shown in Section 10.6. 9.4 Variation of the working distance The thickness that an edge must have to be detected by the SCATEC-2 depends on the working distance. The SCATEC-2 is most sensitive at the nominal working distance which is 40mm for the FLDK 110x1003/Sxx and 100mm for the FLDK 110x1005/Sxx and FLDK 110x1006/Sxx. The relationship between the sensitivity and the working distance is contained in the specifications in Section 10.6. the sensitivity of the sensor varies with the working distance Manual SCATEC-2 Version 2011-05 20 www.baumer.com Baumer Electric AG Frauenfeld, Switzerland 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). Because the yellow edge-LED lights up exactly during the time an edge is in the laser beam, the flashing of the yellow LED may become difficult to recognize by eye when fine edges pass the sensor at high speed. Consequently, at high conveying speed and/or fine edges, supposedly absent flashing of the yellow LED does not necessarily mean malfunction of the sensor. 9.6 not every flash of the yellow edge-LED is followed by an output pulse at a high conveying speed the flashing of the yellow edge-LED may be difficult to recognize Applications outside the paper processing industry Due to the fundamental principle of edge detection employed by the SCATEC-2, the field of application for the sensor is not restricted to the paper processing industry. For applications concerning high-gloss surfaces (e.g. sheet metals), it is advisable to consult a technician from Baumer Electric AG on the application.

Otherwise first try to resolve the problem using the following tables. If this is unsuccessful, consult Baumer Electric AG (www.baumerelectric.com) for technical support. The search for fault causes can be substantially shortened if the following issues are clarified before you make contact with a technician from Baumer Electric AG: 1. 2. 3. 4. What is the part number and P-code of the sensor (see white area on the sensor label)? Give exact description of the problem. (Does the SCATEC count more or less copies than actually pass the sensor?) Retain several samples of the products causing the counting error. (Mark the running direction on one sample and the approximate line along which it passes the laser beam.) If possible, take digital images of the installed sensor in operation and of the immediate surroundings. Manual SCATEC-2 Version 2011-05 Fault 1 Scatec counts less copies than actually pass the sensor Manual SCATEC-2 Version 2011-05 31 www.baumer.com Baumer Electric AG Frauenfeld, Switzerland Possible causes Corrective actions (see manual section x.x) a) Wrong sensitivity setting. Set DIP-swich 4 off. (8; 9.3) b) Copies too close to or too far away from the Scatec, so that the copies are in a distance range at which the sensitivity of the sensor is inadequate. Set the distance of the copies in a range where the sensor is sufficiently sensitive to detect the copies. (10.6) c) Overlap spacing sporadically too small. Increase the overlap spacing or reduce the conveying speed (production rate). (9.1) d) Some copies are completely covered by another copy. Prevent complete coverage of copies. e) Conveying speed too high. Reduce conveying speed. (10.6) f) False pulse suppression active while overlap a is highly irregular or conveying speed is occasionally accelerated very quickly. Deactivate false pulse suppression (DIP-switch 3 set off) or make overlap a more regular or accelaerate slower (9.2) 32 www.baumer.com Baumer Electric AG Frauenfeld, Switzerland 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). c) Unblocked laser beam is reflected and causes false pulses.
