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.
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.
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.
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. 100 Figure 4.3.1 Standard mounting with beam stopper. User Manual DENEX MICRO Version 2013-02, V1.6 7/24 www.baumer.
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.
4.5 Mounting With Reference Surface In some cases, the reflections from parts under the conveyor cannot be screened off. In this case, the following is recommended. Let the laser hit a light, matte surface, reference surface, like a white piece of paper or a light painted plate, at 100 mm below the sensor. The reference surface must be smooth. If the surface is wrinkled or coarse, vibrations can cause error pulses.
5 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 : Pin 2 : Pin 3 : Pin 4 : Pin 5 : Pin 6 : Pin 7 : 5.1 +24VDC power + Output (collector) + Speed Sensor Input - Speed Sensor Input - Output (emitter) 0V No function (connected to pin 6 internally) Power Connection Proper wiring techniques are essential for successful system installation.

Copy Sensor Figure 5.2.1.3 Electrical connection, separate supply for power and pulse. 5.2.2 Speed Sensor Input There is a possibility to connect an input signal from a speed sensor, such as an encoder, in order to give information of conveyor speed. The input can be used to obtain a fixed blocking distance.
6 SOFTWARE FUNCTIONS The real power with a microprocessor-based sensor is that the sensor learns what the products and the stream look like and make decisions according to this. Before actual settings are discussed, first a short description of the major functions and terms. 6.1 Application Setting The sensor can be optimized around certain applications.
6.4 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 = OFF = ON DIP-switches 1-4 are reserved for factory DIP-switches 5-8 are for selecting operation mode All in OFF-position is the default setting.
7 LED INDICATORS As a help for checking the operation of the sensor, there are four LED’s that are placed close to the connector. Figure 7.1 Position of LED:s. 7.1 The POWER-LED The green POWER-LED indicates that the sensor has power and should be operating. Never mount or adjust the sensor when this LED is on! 7.2 The LASER OFF-LED The LASER OFF-LED is an indication that the laser is off.
8 TECHNICAL SPECIFICATIONS Maximum Count Rate < 600.000 copies/hour Maximum Product Speed 1 m/s (200 ft/min) for thinnest product, up to 2 m/s otherwise Maximum Stream Thickness 70 mm (2.76”) standard range Minimum Product Thickness 0,25 mm (0.01”) standard range, Distance From Conveyor 100 mm (3.94”) standard range, Minimum Spacing Between Copies 1-5 mm (0.039-0.20”) dep.
9 LASER SAFETY The concentrated beam of optical radiation from the laser diode is potentially dangerous. In considering the safety aspects of the use of such devices, it is the thermal effects of absorption of this energy, which are important. However, in comparison with higher power laser using different generating media, laser diodes are relatively safe. A Class II-laser product as the DENEX MICRO is said to be safe if a person does not stare into the beam.
10 SAFETY 10.1 Safety Features The following chapter describes the safety features of the DENEX MICRO. Make regular checks to verify the function of these features. 10.1.1 Power Control To power off the sensor, unplug the power connection. 10.1.
12 RETURNING EQUIPMENT If it is necessary to return a DENEX MICRO for repair, the following procedure should be followed. 1. Tag the unit with the following: • Company and contact person returning the item • Phone, fax or email to the contact person for additional information • Helpful information regarding the malfunction. A good description reduces trouble shooting cost. If the unit has been disassembled, reassemble it, making certain that all hardware is in place.
14 TROUBLESHOOTING The green LED (POWER) is not lit • The sensor does not receive +24V on pin 1 and 0V on pin 6 on the Tuchel connector, see chapter 5, ”Electrical Installation”. • If the sensor has been working and is suddenly dead, there could be transients knocking out the sensor. Make sure that the voltage is between 20V and 30V and is regulated. The red LED (LASER-OFF) is lit constantly, and no laser is present • Re-power the sensor. Check that the laser is lit.
The sensor does not read the Speed Sensor Input Signal • Check polarity and levels according to chapter 5.2.2, ”Speed Sensor Input”. Is the speed very high? It should be max. 2.5 kHz. There is an overcount (too few copies in the bundle) • Check the mechanical installation. The sensor must be parallel to the stream. • For cut-edge first delivery, or with copies with stitches or other non-folded edges, try changing the application so that the Blocking Zone is greater, see chapter 6, ”SOFTWARE FUNCTIONS”.
