1 INTRODUCTION

WARNING

When a DENEX Gripper LED 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 Gripper LED 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 Gripper LED is a non-contact sensor which counts all kinds of products
carried in a Gripper. It senses the leading edge and generates one output pulse for every
product. Product thickness from a single folded sheet and up can be sensed without
adjustments.

The Infra Red-Light Emitting Diode (IR-LED) that is used produces a 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.

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 accuracy

• Insensitive to color of paper or print

• Insensitive to product thickness

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

4 INSTALLATION

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

4.1 General Precautions

The DENEX Gripper LED 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 is rigid to
withstand vibrations.

4.2 Mechanical Installation

The sensor should be installed parallel to the conveyor and at a distance of 40 mm from
the copy edge, see figure 4.2.1. 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 meet the
edge first”.

As a “Target”, mount a white surface at 120 to 150 mm below the sensor, and parallel to
the bottom of the sensor. Check that the LED 4 indicates Target Status OK, see chapter 6,
”SOFTWARE FUNCTIONS”. Failure to comply will make the counter less accurate.

Mount the DENEX Gripper LED as close as possible to the Grippers without risking being
in contact with the Grippers. A 5 mm safety distance is recommended.
There must be at least 5 mm of air between the edge that the sensor should detect, and
the previous product.

If the sensor is to be used together with a Gripper pulse, it must be possible to move the
sensor sideways for the length of one Gripper, see figure 4.2.2. See further chapter 6.3,
”Gripper Pulse Mode”.

5 ELECTRICAL INSTALLATION

The copy sensor has a 7-pin male connector with the following pin-out:
Matching female connector is Amphenol Tuchel T3476 001, delivered with the sensor.
Pin 1 : +24Vin

Pin 2 : + Output (Collector)
Pin 3 : + Speed Sensor Input
Pin 4 : - Speed Sensor Input
Pin 5 : - Output (Emitter)
Pin 6 : 0V
Pin 7 : No function (connected to pin 6 internally)

5.1 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 19 - 30V DC regulated power.
It must be free from transients!
Never connect or disconnect any cables when the power is on!
The normal current consumption is around 200mA.

5.2 Output Signal

The output is a normally open, opto-isolated transistor. Every output pulse is signaled as a
closing of the output; see “DIP-Switch Settings” in chapter 6.4.
The specification for the output opto-coupler is as follows:

Max load current: 150mA
Max voltage: 35V DC

5.2.1 Output Signal - Connections

The output can be used for both "current source" and "current sink" depending on what is
required for the connected equipment. It can be normally open or normally closed, see
chapter 6, ”SOFTWARE FUNCTIONS”.
In current source mode, the sensor output will give a positive output pulse when active.
In current sink mode, the sensor output will give a negative pulse.
Figures 5.2.1.1 and 5.2.1.2 show a common 24 VDC as power supply and as the supply
for 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 output is connected to pins 2 and 5, see figure 5.2.1.3.
