WEB GUIDE CONTROL SYSTEMS

System components 35Line Follower Head LH500The latest imaging technology to keep slit failures to an absolute minimum.The Line Follower Head LH500 is a sensor that optically detects register lines or patterns printed on a web. In combinationwith a controller, the LH500 can be used to form an EPC (Edge Position Control) and LFC (Line Follower Control) system.? Printed lines stored as image informationThe new system is highly effective and keeps track of storedline information, even if register lines and printing accessoriesare mixed.? Automatic optimization of illuminant color and light volumecompleted simply by pressing the search buttonThe sensor has an automatic light adjustment functionwhich can be used also for highly reflective material, such asaluminum foil and copper foil.? Central positioning simple with laser pointerThe device is equipped with a laser pointer, improvingvisibility of control position.? LED bar makes detection status easy to seeThe detected object and detection status can be seen at aglance. Use the search button to toggle between operatingmode (deviation display) and search mode (pattern display).Line Follower Head LH500 stores detected lines as image information, which it uses to perform pattern matching and comparisonoperations on image information during operation. With this new system, even if register lines and printing accessories are mixed, thestored lines are always tracked.LH500 operating proceduresControllerSearch recognitionbuttonLine (dark)LED bar detection pattern displayLine (light) Edge EdgeLaser pointerON when irradiating ERROROKREADYERRORREADYOKSearch modeRecognitionMemoryAmp autoLamps and LED barsLitFlashingUnlitSpotlight distanceWith diffuser plate: 1 mm(from web surface to diffuser plate surface)No diffuser plate: 15 mm(from web surface to main unit surface)Detection range 7 mm (with reference to memory pattern position)Pattern memorywidth 3 mm (main unit center)Light source Blue and red high luminance LEDOutput1) Position signal (voltage output):0.7 to 4.3 V DC (High) 0.07 to 0.43 V DC (Low)2) Actuator lock signal:Open collector output 30 V, 0.1 A or lessON conditions: pattern errors or outside ofpattern field of view, in search modeDetection element CCD linear image sensorPixel resolution 14 μmPower supply +15V DC, 250 mA / -15 V DC, 30 mAAmbienttemperature 0 to +50?CAmbient humidity 35-85% RH (no condensation)Protective structurerating IP50Laser Class 2 (IEC), ON/OFF switch (for laser pointer)Body material AC4COuter dimensions 108 (H) × 58 (W) × 50 (D) mm(projected part is not included)Mass Main unit: 0.5 kg Screw guider: 0.5 kgCables LH500 cable (optional) Model: MD0002640-70Conversion cable (optional) Model: MD0002640-80
