General information 1.1 Packaging and storage In order to ensure adequate protection during transportation the products have been carefully packed. On receipt, the goods and the packaging should be checked for damage. In case of damage the equipment must not be operated! Damaged cables or connectors are a risk to safety and, likewise, must not be used! If this is the case please contact your MOBA-supplier. If the equipment is not to be used directly after it is unpacked it must be protected from dampness and dirt. 5 1.2 Precautionary measures Please carefully and completely read the instruction manual before mounting, operating and using the equipment. Should there be any questions please contact your MOBA-supplier. Safety measures: The safety measures recommended here basically correspond to the guidelines for installation and commissioning of electrical systems. They can be adopted to all applications referring MOBA-equipment. Mounting: When mounting the equipment only original MOBA-cables may be used. The connectors may not be disconnected from the cables as they are protected against dampness. Any opening would destroy this protection. Make sure that the securing screws of all the connectors are tightened. Further mounting information referring the equipment and the sensors can be taken from the enclosed data sheets and operating instructions respectively. Wiring and cabling: The wiring and cabling has to be carried out correctly, according to the instructions given in this manual. All supply lines and connecting terminals have to be sized according to the corresponding intensity of current. Furthermore, all connections have to be made in accordance to the valid VDE-regulations and the valid national regulations respectively. Interference resistance: This equipment has been designed for industrial use and has been tested correspondingly. Nevertheless, microprocessor technology puts certain demands on installation. We would therefore like to point out the following installation facts which, if not taken into account, later can cause operational disturbances: 6 • Make sure that the connection polarity is correct; • Supply voltages may not exceed or fall short of the given range; • Protect the equipment with a suitable pre-fuse; • Use cable diameters suitable to the voltage and current intensities respectively; • Make the cabling paths as short as possible (avoid loops); • Install load, control and measuring lines as separate as possible; • Suppress contactor and relay coils; • A disturbance-free operating requires a good electrical connection between the machine chassis and the housing chassis of the individual components; • Connect screened cables to earth and at one end only (equipment end); • Do not supply other equipment directly from the connecting terminals of the power supply; • Do not use unutilised terminals for other connection points or for other equipment • Before welding disassemble the system components or at least disconnect the power supply Maximum voltages: Do not exceed the allowed maximum voltages. The maximum voltage between any two isolated circuits or between circuit and earthing is, if not otherwise noted, limited to the maximum value of the corresponding input voltage and supply voltage respectively. The connecting terminals or plugs have to be equipped with a suitable pre-fuse. Fuses: To prevent polarity reversal, voltage peaks and temporary over-voltages the equipment is fitted with electronic fuses. The supply voltages given in the technical data may not be exceeded. 7 Configuration: The equipment may be configured by the user. When reconfiguring, the user is obliged to allow for the system conditions. Alarm device: In complex systems in which a malfunction can harm the operating personnel’s health or cause system destructions, the use of an independent alarm unit for process supervision makes sense. An independent alarm unit offers protection by setting off an alarm and switching off the system in the event of an alert. In many cases the use of an alarm unit built into the controller does not provide adequate protection as it does not work independent from the control system. Explosive areas: The equipment is not designated for use in explosive areas. Fault clearance: Before starting to clear faults make sure that every voltage supply to the equipment has been disconnected. Faulty equipment should be examined in an area suitably fitted for test purposes. Every attempt to correct a fault in equipment still installed could be dangerous for the personnel and the system. Before removing or replacing sensors in the system make sure that the voltage supply has been disconnected. Ask for help If there are questions referring operating or mounting please contact your MOBA-supplier. In case the above precautionary measures are not observed, this can lead to equipment or machine failure. Damages traceable to non-observance of the precautionary measures manufacturer’s guarantee. described above are excluded from the 8 1.3 Instructions regarding operational safety General instructions • Always switch off the Digi-Sonic III System before leaving the driver’s seat or when the machine stands still. • Never carry out any work on the sensory mechanism when the system is in automatic mode. • If safety-relevant machine parts have to be removed in order to mount system components, these parts definitely have to be put back in place before initial commissioning. • Note the safety instructions provided by the machine manufacturer. When working on the electrical system • Any work on the machine’s electrical system has to be performed by trained specialised staff. • Disconnect the negative pole of the machine battery during the electrical installation. • To reduce the system’s interference liability to a minimum make sure that a good electrical connection is created between the machine chassis and the housing chassis of the individual components during the installation. • Do not use unutilised terminals for other connection points or for other equipment. 9 When welding • Before welding disconnect the negative pole of the machine battery and, if possible, dismount all electronic components and disconnect their power supply respectively. Arc welding creates very strong currents which may destroy the machine’s electronic system. • Place the negative electrode of the welding outfit close to the point where the weld is to be. • Remove the varnish from the intended fixing point and the holding device to be welded on. Prime and lacquer the weld seams when the job is done. • Protect combustible parts from flying sparks. • Never look into the arc without wearing safety glasses. 10 2.

System description The Digi-Sonic III System consists of a contact-free working MOBA Digi-Sonic Sensor III and the control unit “Feeder Control“. It is used to precisely control the material quantity in front of the screed of asphalt pavers. The Digi-Sonic III System can be used for the auger control as well as to control the conveyor. Operational description for using the MOBA Digi-Sonic Sensor: The MOBA Digi-Sonic Sensor sends ultrasonic waves that are reflected by the material surface. According to the time period measured between sending the ultrasonic waves and receiving the reflections the sensor calculates the distance to the fitting material. After the desired material height is adjusted with the help of the potentiometer at the control unit the Digi-Sonic III System detects every change of height and calculates the deviation scale. The controller triggers the auger until the wrong height is corrected and that way keeps the material quantity constant. Alternatively the control unit “Feeder Control“ can also be operated by a existent paddle sensor attached to the machine or another analogue sensor. 13 Due to its easy appliance via rotating knob, the easy and flexible assembly of the system as well as its reliable functioning, the Digi-Sonic III System is an efficient and easy to handle controlling system for your machine. The systems advantages at a glance: • contact-free sensing, that is no abrasion and no jamming • detection of status via LED display • outputs for different valve types adjustable • high ease of use • easy assembly at well accessible and nonhazardous sites • retrofit • reliable and precise functioning 14 Overview of the system components: Components Description Item number MOBA Digi-Sonic III 04-37-56130 Control unit “Feeder Control“ for Digi-Sonic III System 04-45-00085 Brackets for the quick and easy assembly of the MOBA Digi-Sonic III on request Coil cable to connect the control unit to the sensor 04-02-00280 Machine-specific coil cable to connect the control unit to the machine on request 15 4. Appliance and display elements 1 Rotating knob with scale label 2 Metering mark of the catch block 3 Power-LED 4 Output-LED 5 6-pin plug (machine) 6 6-hole socket (sensor) The rotating knob of the potentiometer (1) is the only classic appliance element of the Digi-Sonic III System. By turning the rotating knob clockwise the material supply in front of the screed is increased; by turning it counter-clockwise the supply is decreased. For better orientation the rotating knob features a scale label and the catch block has a metering mark (2). A high numerical value indicates more material while a low numerical value means less material.

Assembly and installation The assembly and commissioning of the Digi-Sonic III System have to be carried out by skilled and qualified specialised staff! Qualified specialised staff in terms of this manual are persons that are familiar with the assembly, commissioning and operation of the product and possess qualification according to their tasks. 5.1 Assembly information for the MOBA Digi-Sonic III The Digi-Sonic III System can easily and quickly be assembled with common tools. To mount the MOBA Digi-Sonic III Sensor different brackets are available. To receive reliable measured values the MOBA Digi-Sonic III has to be assembled in a way that the sound hits the material as vertical as possible. In ultrasonic reflection: angle of incidence = angle of reflection A distance change to the material has to in an instantaneous speed rotational alteration of the auger and alteration of respectively. the conveyor speed ° 90 result 18 Frequent assembly errors and causes for malfunctions Due to inappropriate mounting of the MOBA Digi-Sonic Sensor an angle deviation to the vertical occurs between sensor and material. The controller shows malfunctions because a reliably analysable sound pulse cannot or can only be received sporadically. There is a foreign object in the sound beam range of the MOBA Digi-Sonic Sensor. a) When the foreign object is fully detected there is no change of the distance value and therefore the auger’s speed of rotation is not controlled. b) When the foreign object is situated at the border area of the sound beam the measured value of the sensor can fluctuate between the object and the material surface. This leads to erratic changes in the auger’s speed of rotation control. 19 The MOBA Digi-Sonic Sensor does not detect the material surface but reacts to the constantly changing distance value to the rotating paddle wheel of the auger. The Digi-Sonic System does not control the material quantity. The MOBA Digi-Sonic Sensor has been mounted at a position where it is to close to the hot fitting material and/or where the ambient temperature permanently heats up to over 85°C. Malfunctions and damages of electronic components can occur. If this is the case the controller works unreliably or not at all. 20 The specified working range of the MOBA Digi-Sonic Sensor has been under- or over- h ic re e e b g ts n ei g ra b r n r A ki tr e wor e zi d ifi ifie z e ec sp sp run (also see technical data). It is not possible to control the augers speed of rotation because in both cases no reliably analysable sound pulses can be received. ch ei e r be g its ran e rb ing r A rk tr e wo ie d fiz ie zi cif e e sp sp 21 The sound beam of the MOBA DigiSonic Sensor is limited by a parallel, even wall. Walls – even if polished - cause reflections. The resulting sound rates disturb the MOBA Digi-Sonic Sensor and interfere massively with the controller. An additional collimating of the emitted ultrasonic pulses by attaching a pipe to the MOBA Digi-Sonic Sensor therefore is not possible! 22 5.2 Assembly information for the control unit “Feeder Control“ The control unit ”Feeder Control“ should be mounted at a splash- and soil-proof position. The rotating knob has to be reached easily and the cabling of the machine and the MOBA Digi-Sonic Sensor has to be possible without having to disassemble the control unit. The circuit points have to face downwards to protect the connector plugs from water infiltration. For information about the connecting dimensions please see the technical data in this manual. 5.3 Attaching the connection cable to the MOBA Digi-Sonic Sensor To machine 04-02-00280 Attach the 6-pin cable plug of the connection cable to the 6-hole connector socket of the control unit “Feeder Control” and attach the 6-hole cable socket of the connection cable to the 6-pin connector plug of the MOBA Digi-Sonic Sensor. 23 5.4 Alternative connection of an existent paddle sensor Schematic connecting diagram Gnd B signal D E paddle sensor +8V 6 hole connector socket 5.5 Machine connection The design of the machine connectors and machine cabling manufacturerspecifically varies significally. In addition there are two different valve types for the material control in asphalt pavers. Prop valve: For this valve type a “dosed“ electrical triggering is feasible; that is the auger and the conveyor respectively can be operated with variable speed. Therefore the controller can react to the different conditions in diverse intensity. ON/OFF valve: This valve type generally can only be switched on and off. It offers less microcontrol than the “prop valve”. The ON/OFF valve can be identified by the fact that there is only one auger velocity and conveyor velocity respectively. For some asphalt pavers your MOBA-supplier can provide you with cables for connecting the control unit “Feeder Control” and the machine. In many cases, however, the machine connection has to be conducted individually. 24 To be able to use the full functional range of the system as described in this manual, the cabling has to be undertaken completely and according to the following outlines. Interconnect the operating mode switch as described and note the individual differences when connecting the different valve types. 5.5.1 Connection prop valve, PNP, with I max = 150 mA 8 Amp. + Batt. - Batt.

Working with the Digi-Sonic III System 1) Manually convey the material quantity in front 2) Turn the rotating knob of the control unit 3 of the screed up to the desired height. “Feeder control“ to its left stop position. (scale reading = 0). 3) Position the MOBA Digi-Sonic Sensor at a distance of 30 up to 80 cm above the material. Switch the Digi-Sonic III System to the 3 4) operating mode “Automatic“. The green powerLED is beaming constantly. 27 5) Now slowly turn the rotating knob of the control unit “Feeder Control“ clockwise until the auger just starts running. 3 As the output of the control unit now is active, the red output-LED is beaming. 6) In case the material height changes during the assembly this will be detected by the sensor. By accelerating or decelerating or on- and offswitching of the auger (depending on the valve type used) the material height will be automatically corrected by the control unit ”Feeder Control”. 3 7) Increase or decrease the material height by using the rotating knob at the control unit “Feeder Control” (working point shift). Turn the rotating knob clockwise to increase the material height and counter-clockwise to decrease it. 28 6.1 Operating mode “manual“ when using a prop valve This mode allows the operating of the Digi-Sonic III System without having to use a sensor or external switches. 1) Switch the Digi-Sonic III System to the 3 operating mode “manual“. The green power-LED is blinking. 2) Increase or decrease the auger speed by using the rotating knob at the control unit “Feeder 3 Control”. At the left stop position (scale reading = 0) the auger works with minimal speed (1) , at the right stop position (scale reading = 10) it works with maximum speed The intensity (2) . of the output triggering is 3 additionally visualised by increasing and decreasing brightness of the red output-LED. (1) + (2) When operating the Digi-Sonic III System with a proportional valve the minimal and maximum speed of the auger is adjustable. See section “ 7. Configuration“ in this manual. 29 6.2 Operating mode “manual“ when using an ON/OFF valve This mode allows the operation of the Digi-Sonic III System without having to use a sensor or external switches. 1) Turn the rotating knob at the control unit “Feeder Control“ to a scale reading < 5. 3 Switch the Digi-Sonic III System to the operating mode ”manual“. The green power-LED is blinking. 3 2) Switch the auger on or off by using the rotating knob at the control unit “Feeder Control”. At a scale reading < 5 the auger is switched off, at a scale reading > 5 the auger is switched on. When the output of the control unit is switched on the red output-LED is beaming. 3 30 7. Configuration Any configuration of the system may only be carried out to the described extent! Deviant rebuildings or alterations of the system are illegitimate and constitute a non-intended use. The control unit “Feeder Control“ features two valve outputs (see section 9 “Technical data” in this manual) . The valve output 1 is solely designed for the use of a proportional valve with a maximum of 150 mA . The valve output 2 can be configurated in a limited range. The cabling of the 6-pin connector plug first of all defines the valve type used in your machine (see section 5.5 “machine connection” in this manual). When using a proportional valve at the valve output 2 of the control unit “Feeder Control“ via the variables “min-current“ and “max-current“ additionally the minimum and maximum triggering of the valve - and therefore also the minimum and maximum speed of the auger - can be adjusted. Definition of terms Min-current: The min-current is the minimum electricity emission at the “dosed” triggering at the valve output 2 of the control unit. It is adjustable within set limits (0% - 50%). The min-current defines the lowest rotation speed of the auger. Max-current: The max-current is the maximum electricity emission at the ”dosed” triggering at the valve output 2 of the control unit. It is adjustable within set limits (50% - 100%). The max-current defines the highest rotation speed of the auger. 31 7.1 Programming adaptor To adjust min- and max-current you need a programming adaptor, which can be manufactured from a few components. Schematic connecting diagram B Gnd push-button switch E F 6 hole connector socket +8V 10k Input programming adaptor 32 7.2 Min-current and max-current adjustments 1) Switch off the power supply of the Digi-Sonic 3 III System. The green power-LED is off. Turn the rotating knob of the control unit ”Feeder Control“ to its left stop position (scale reading = 0). Disconnect the sensor cable and instead 3 2) plug the programming adaptor into the 6-hole connector socket of the control unit. Switch on the power supply of the Digi-Sonic III System. The green power-LED is blinking quickly. 3 3) Now slowly turn the rotating knob of the control unit “Feeder Control“ clockwise until the auger runs with the desired entry speed. We recommend: Until the auger just starts rotating! As the output of the control unit “Feeder Control“ now is active, the red output-LED is glowing. 33 3 4) Push the button at the programming adaptor and this way save the min-current. During the saving process the green power-LED only is blinking slowly. After the saving process has finished the green power-LED is blinking quickly again. Now slowly turn the rotating knob of the control unit “Feeder Control“ further clockwise until the auger has reached the desired maximum speed. As the output of the control unit “Feeder Control“ is triggered more intensely than before, the red output-LED brightness. now is beaming with higher 3 5) 34 6) Push the button at the programming adaptor again and this way save the max-current. During the saving process the green power-LED Afterwards the Digi-Sonic III System automatically switches back to its regular operating mode. Disconnect the programming adaptor and plug the sensor cable into the 6-hole connector socket of the control unit. The system now is ready for operation again. In case the adjustments need to be altered the procedure has to be repeated. 3 only is blinking slowly. 35 8. Maintenance and upkeep 8.1 General information The Digi-Sonic III System has been designed to conform to high operational safety. The system can be maintained with only minimum effort. All electronic components are built into robust casings to prevent potential mechanical damage. Nevertheless, the equipment as well as the connection cables should be checked for potential damages and impurities at regular intervals. To prevent poor contacts, the thread of the plug connection and the cable glands have to be kept free of soil, grease, asphalt or other foreign material. 8.2 Remarks referring the equipment cleaning 1) Switch off the Digi-Sonic III System; 2) Apply a customary cleaner for synthetics on a soft, lint-free cloth; 3) Clean the equipment surfaces without pressing; 4) Completely remove the cleaner of the equipment with a clean cloth; 36 9. Technical data On the following pages you will find data sheets referring the different system components. Besides a dimensioned diagram of the device they contain a description of its interfaces and several basic technical remarks. All components of the Digi-Sonic III System feature an inverse-polarity protection, an over-voltage protection as well as several EMC-safety measures to achieve the highest operational safety possible. 37 Artikel-Nr.: 04-37-56130 Abmessungen (Dimensions): 1 22 1 A B F C D 128 E 59 2 2 Technische Daten (Technical data): Spannungsbereich (voltage range): 10,5 … 35 V Spezifische Daten (Specific data): Ausgang (output) 1: PWM, NPN (I max = 70 mA) Schematische Darstellung (schematic diagram): Stromaufnahme (current consumption): < 65 mA V Min.Puls PWM Freq.
