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 Ris located close to the laser light source
and photodetector Va 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 Vto the point of contact of the
laser is obstructed, which reduces signal v, and the edge
also increases the backward scattering, causing signal rto
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.

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.

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) Bysetting 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
www.baumer.com Frauenfeld, Switzerland
A helpful rule of thumb is: Output pulse length pin 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

2 600,000
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.
Manual SCATEC-2 18 Baumer Electric AG
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

Manual SCATEC-2 21 Baumer Electric AG
Version 2011-05
www.baumer.com 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.
Manual SCATEC-2 32 Baumer Electric AG
Version 2011-05
www.baumer.com Frauenfeld, Switzerland
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 sufficientlysensitive 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 ofcopies.
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 ais highly irregular or
conveying speed is occasionally
accelerated very quickly.
Deactivate false pulse suppression (DIP-switch 3
set off) or make overlap amore regular or
accelaerate slower (9.2)

Manual SCATEC-2 33 Baumer Electric AG
Version 2011-05
www.baumer.com 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 theconveyor speed.
Scatec-10 and –15 can be synchronized.
