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
