1 INTRODUCTION

We strongly recommend you to read section regarding laser safety before switching on the
equipment.

WARNING

When the DENEX MICRO is combined with user

selected components to form a system, the user is responsible for proper selection of parts

and subsequent operation. This unit shall be installed, adjusted and serviced only by

qualified personnel who are familiar with the operation of the DENEX MICRO and other

system components. Serious personal injury and equipment damage may result if this

procedure is not followed.

2 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 later, notify the freight or express agent.

3 BASIC FUNCTION

The DENEX MICRO 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
which 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 3.1 The principle of operation

The patented principle in utilizing two detectors - one for detecting the obstructed light and
the other for reference, enables the following unique benefits:

Wide operating range

High precision
Insensitive to color of paper or print
Insensitive to product thickness
Insensitive to variations in distance to copy stream

The use of a microprocessor further enhances the flexibility and reliability of the unit.
Through the use of the microprocessor, the DENEX MICRO can be adapted to different
operating modes by changing DIP-switch settings which can be reached from outside, via
the glass window.

4 INSTALLATION

In order to assure the best possible operating conditions as well as personal safety, it is
essential that the following instructions are followed exactly.

4.1 General Precautions

The DENEX MICRO 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.
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 4.1.1 (right) since it will deteriorate the function of the unit.

YES NO

Figure 4.1.1 Mounting on a non-flat conveyor.

4.2 Mechanical Installation

The sensor should be mounted parallel to, and at a distance of 100 mm from the conveyor.
The sensor will then count folded sheets up to a maximum stream thickness of 70 mm. If
the sensor is to used as a gripper sensor, refer to Appendix 1 ”Mounting and using the
sensor on a gripper conveyor”. Contact Baumer if other mountings are considered. It is
most important that the sensor is mounted the right way. It can only count in one direction.
The connector side of the sensor should be the first to meet the copies.

The laser beam must not hit any moving part of the conveyor. The path of the laser must
end with a beam stopper. See chapters 4.3 and 4.4 for more information about the type of
beam stopper used. The laser beam must never be accessible to the user!

Make sure that the mounting bracket used is rigid and that the alignment of the unit cannot
be accidentally changed. There are brackets available from Baumer.

4.3 Standard Mounting with Beam Stopper

The laser does not hit anything except the beam stopper when no copies are present.
Normal back-edges will not be counted with this mounting. The beam stopper is a black
plate or dark surface no closer than 300 mm to the bottom of the sensor. See figure 4.3.1.

4.4 Mounting with a hole for the laser

If there are mechanical parts 200-300 mm under the sensor that can cause reflections to
the detectors, the following mounting is recommended. It requires a small hole on the
conveyor, or a plate with a hole to screen off the reflection from the parts. The beam must
still be stopped with a dark plate or other material if there is any risk for a person to look
into the laser. Make sure that the laser goes through the hole properly. Normal back-edges
are not counted with this mounting.
