1 RECEIVING AND HANDLING
Upon delivery of the equipment, thoroughly inspect the shipping containers and contents
for indications of damage incurred in transit. If any concealed loss or damage is
discovered, notify the forward agent.
A complete DENEX Edge Detector II shipping box should contain:
1 DENEX Edge Detector II
1 Female Connector, Amphenol Tuchel T3476 001

2 BASIC FUNCTION
The DENEX Edge Detector II is a non-contact sensor, which counts all kinds of printed
products on an overlapped stream. It senses the leading edge and generates one output
pulse for every product. Product thickness from a single folded sheet up to a maximum
stream thickness of 70 mm can be sensed without adjustments.
The laser diode that is used produces a visible and very intensive and focused light beam
that is projected onto the stream. The reflected light from the spot is collected by two light
sensitive detectors P and R and is analyzed by a microprocessor. The difference in
reflected light that occurs, when the light spot is temporarily hidden behind the passing
product edge provides the basic data for the sensor to determine a count output pulse.
Figure 2.1 The principle of operation
The microprocessor controlled DENEX Edge Detector II can be adapted to different
operating modes by changing DIP-switches, which can be reached from outside, via the
lid.

3 INSTALLATION
3.1 General Precautions
The DENEX Edge Detector II should be installed in an environment where:
1. The equipment ambient temperature does not exceed 40º C.
2. The equipment atmosphere is free from highly flammable or combustible vapors,
corrosive chemical flumes, oil vapor, steam, excessive moisture and particles.
Avoid mounting the unit in places with strong vibrations since they can produce miscounts,
especially when thin products are counted. Make sure that the mounting bracket and
means used are rigid to withstand vibrations.
3.2 Mechanical Installation
The sensor should normally be mounted on a flat conveyor. It is possible to mount the
sensor on a bent part of the conveyor according to figures below. Do not mount according
to Figure 3.2.1 (right) since it will deteriorate the function of the unit.
YES NO
Figure 3.2.1 Mounting on a non-flat conveyor.
The sensor should be mounted parallel to, and at a distance of 100 mm from the conveyor.
When the laser does not hit a product, it should hit a light, matte surface at 100 - 150 mm
below the sensor. The reference surface must be smooth. If the surface is wrinkled or
coarse, vibrations can cause error pulses. Also, make sure that dust and paper pieces do
not stay on the surface, since they could also create output pulses. Make sure that the
laser beam is properly stopped by this surface, so that it is impossible for a user to be
exposed to the laser beam.

3.3 Electrical installation
The interface to the copy sensor is a 7-pin connector with the following pin-out:
Matching connector: Amphenol Tuchel T3476 001, delivered with the sensor.
Pin 1 : +24VDC in
Pin 2 : + Output (collector)
Pin 3 : Not connected
Pin 4 : Not connected
Pin 5 : - Output (emitter)
Pin 6 : 0V
Pin 7 : No function
3.3.1 Power Connection
Proper wiring techniques are essential for successful system installation. To reduce the
effects of electrical noise interference and static discharge, the procedures outlined in this
section must be strictly followed.
The sensor shall be connected to 24 VDC regulated power.
It must be free from transients!
Never connect or disconnect any cables when the power is on!
The normal current consumption is 150 mA.
3.3.2 Output Signal
The output is a normally open, opto-isolated transistor. Every output pulse is signaled as a
closing of the output for a certain time; see also “DIP-Switch Settings”
The specification for the output opto-coupler is as follows:
Max load current: 100 mA
Max voltage: 35VDC

3.3.2.1 Output Signal – Connections
The output can be used for both "current source" and "current sink" depending on what is
required by the equipment. In current source mode, the sensor output will give a positive
pulse to the stacker/totalizer when active. In current sink mode, the sensor output will give
a negative pulse. Figure below shows a common 24 VDC as power supply and feeding the
pulse. It is possible to have different power supplies. In that case, the 24V power is
connected to pins 1 and 6, and the totalizer can be connected to pins 2 and 5.

4 SOFTWARE FUNCTIONS
The benefit with the microprocessor-based copy sensor is that the sensor learns what the
products and the stream look like and make decisions according to this.
Application Setting
Things like output pulse width, Blocking Function and other parameters are set a little
different for each application in order to reach the highest possible accuracy.
There are DIP-switches that tell the sensor which application it should be set for.
It is very important to set the right application!
4.1 Blocking Function
This function will eliminate false counts due to double edges or a cut-edge-first delivery.
The sensor will count edges coming within the blocking zone as one product. In
productions using stitches, extra pulses due to the stitch are blocked out by this function.
The blocking zone is a dynamic value that constantly adapts to the average distance
between copies. It will be 15%, 30 % or 46% of the average lap, depending on application.
The average distance between copies is 100%, see figure 4.1.
Figure 4.1 The principle of the blocking function. The blocking zone is marked with grey.
15% is dark grey, 30% both grey sections.
The 46% blocking zone is marked with arrows.
For irregular product streams where the lap distance between each copy varies much, the
above described blocking function, can block out copies. This gives the result that there
are too many copies in each bundle. For such cases a special mode is available in the
software, Mode 11.
Our general recommendation is to try to adjust the machinery and get correct stream
conditions, so the lap distance between each copy becomes equal.

4.2 DIP-Switch Settings
An 8-pole DIP-switch can be reached via the lid on top of the sensor. Unscrewing the
screw opens the lid.
The software functions can be controlled via the DIP switches.
DIP-Switch positions

DIP-switches 1-4 are reserved for factory.
DIP-switches 5-8 are for selecting operation mode

5 LED INDICATORS
There are four LED’s that are placed close to the connector.
Power (Green)
Laser off (Red)
Output (Orange)
Not used ( ellow)Y
5.1 The POWER-LED
The green POWER-LED indicates that the sensor has power and should be operating.
For laser safety reasons never mount or adjust the sensor when Power-LED is on!
5.2 The LASER OFF-LED
The LASER OFF-LED is an indication that the laser is off. The laser will be shut off for the
following reasons:
•The laser power has exceeded the allowed limits (electronic problem inside sensor)
•The laser power has reached lower than acceptable level (laser is worn out, or
electronic problem)
If the laser levels are outside of the allowed limits, the sensor must be sent for repair.
5.3 The OUTPUT-LED
The OUTPUT-LED is active when the output stage is active (set). The LED will flash for
every output pulse.
