LBS USER MANUAL LMI Sensors 95 Valkenburgerweg 223 6419 AT HEERLEN The Netherlands Telephone 31 0 45 5719300 Fax 31 0 45 5742500 Serial number __ B04___ SAFETY REGULATIONS The LXS range from LMI Sensors 95 are precision instruments in which a semi conductor laser is being used as a light source Power 5 mWatt Spectrum 670 nm visible red light According to the European Safetynorm the laserdiode is classified in classe Ia Do not point the sensor at any person Labels The following labels must always be shown perceptible on the lasersensor if not possible in the direct surrounding Standard the sensors have been supplied for the required labels by LMI Sensors 95 Standard Laser Symbol A LASERBEAM Classification laser VISIBLE LASER RADIATION AVOID DIRECT EXPOSURE TO BEAM LASER DIODE x MILLIWAT MAXIMUM OUTPUT CLASS Y LASER PRODUCT General The producer and supplier are not responsible for damage which is caused by inexpert use and or faulty working of the sensor In connection with safety reasons the lasersensor only needs to be installed and maintained by authorized personnel In cause of malfunction please contact LMI Sensors 95 INSTALLATION When installing the Laser Beam Sensor you need to take the following items into account During assembling and maintenance the sensor needs to be switched off This to prevent somebody looks into the2. laserbeam per mistake A non solid attachment of the sensor will effect the measurement negatively In spite of the sensor housing being extremely robust and the electronics optics and laser being protected in this way you need to take into account that vibrations c q Resonances in the system can cause undesirable measuring faults Since this is an optical system you need to prevent the lenses to get dirty This has a negative effect on the measurement The cleaning of the lenses needs to take place with a suitable means for that for example optical cleaning cloth A clean environment is recommended Smoke and dirt can influence the laserbeam The maximum temperature on which the semi conductor laser may be exposed amounts to 50 C Avoid direct radiation from sunlight Place the transmitter and the receiver in line For the connections of the sensors see chapter Connections Switch on the system and reckon with the warming up time With the potentiometer on the receiver you can adjust the amplification factor Notice the following steps Receiving no laser light Output voltage OVolt Receiving 100 laser light Output voltage 10Volt Adjust the output voltage 10Vdc with the potentiometer Connections Transmitter brown 15 to 30 Vdc black green GND Receiver brown 15 to 30 Vdc black green GND yellow OUTPUT N B Only use a linear powersupply Make sure the positive and negative supp
