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

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

3 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: 
• 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.

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 
only issue the next pulse after 
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 
pulse. 
False pulse  Output pulse generated by an edge which should not be counted.

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.

7 Installation 
7.1 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. 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.

Overlap orientation  The copies are counted when the edge facing the laser beam moves 
through the beam. 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.

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

8 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. Set all switches to OFF (at least one must have been ON previously) 
2. Set all switches to ON within 16 seconds 
3. Set all switches back to OFF within 16 seconds 
4. 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.

9 Instructions for use 
9.1 Output pulse length and maximum counting rate 
On the one hand, the duration of an output pulse must be long enough so that the customer’s control 
system can process it. 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.

 Manual SCATEC-2  17  Baumer Electric AG 
 Version 2011-05

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.

[milliseconds]

production rate

5  240,000 
10  120,000 
15  80,000 
20  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.

 Version 2011-05
www.baumer.com
Frauenfeld, Switzerland 
9.2 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.

9.3 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

 Version 2011-05

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. 
 
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 
9.6 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.

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. 
13 Troubleshooting 
Whenever possible use the application software ScaDiag for trouble shooting ! 
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. What is the part number and P-code of the sensor (see white area on the sensor label)? 
2. Give exact description of the problem. (Does the SCATEC count more or less copies 
than actually pass the sensor?) 
3. 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.) 
4. If possible, take digital images of the installed sensor in operation and of the immediate 
surroundings.

Fault  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) 
1
Scatec counts less 
copies than actually 
pass the sensor 
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)

 Version 2011-05

Frauenfeld, Switzerland 
Fault  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. 
Install beam blocker at proper distance. 
2
Scatec counts more 
copies than actually 
pass the sensor 
d) Conveyor belt stands still and 
vibrates while an edge is still in the 
laser beam. 
This problem can be eliminated only by 
synchronizing the sensor to the conveyor speed. 
Scatec-10 and –15 can be synchronized.
