ELECTRO-TECHNOLOGY FOR INDUSTRYTechnologyTypes of beaconVisual signaling takes place by means of colour, light intensity and lighting duration. Four types of beacons withdifferent signaling effects are essentially offered in signal technology;Continuous lights – lowest signaling effectThe light intensity of the continuous light changes with the power of the lamp and the use of different colours andtypes of lenses. This type of beacon is normally used to display a status and serves to a lesser extent as a meansof an alarm.Blinking lights – increased signaling effectThe observer’s attention is increased by means of switching the lamp on and off with a blinking frequency ofnormally 1 to 2 Hz. This type of beacon is used, for example, as a warning signal.Rotating mirror lights – high signaling effectA rotating light cone is generated by means of diverting the light using the internal rotating mirror. Higher attentionis gained at faster rotary speeds. Smooth lenses are used for these beacons in order to exploit the light effect to itsfullest and to avoid scattering effects. As opposed to fl ashing beacons, the dazzling effect is reduced with rotatingmirror beacons.Flashing lights – highest signaling effectThe charged capacitor discharges its energy into the gas-fi lled glass tube and forms a light arc. This very short andvery intensive light effect generates the highest signal attention. Among other things, this type of beacon is used asa top priority alarm.Meaning of the colours in visual signalingThe signal colours red, amber, yellow, green, blue and clear are mainly used in signal technology.Different lamp colours convey different messages to the observer in accordance with EN 60078, EN 981 andDIN VDE 0199.ColourProcessstatus(as per IEC 73)Processdata(nach IEC 73)Meaning /message categoryPurposeUser reaction(as per DIN VDE 0199)Exampleapplicationredemergencylimit valueexceeded• danger• abnormal status• act immediately• urgent rescue orprotection measure• emergency• alarm• stop• prohibited• failureimmediate reaction• stop sign• prohibiting sign• emergency stop devicesyellow /amberabnormalwarning limitreached• caution• be prepared• act if necessary• attention required• change of status• interventionmonitor and/orinterveneindication of dangers,such as: fi re, explosion,radiation, chemical infl u-ences, obstructions etc.greennormalwithin normalrange• everything ok• normal status• safe• no danger• danger is pastr• first aid• return to normal process• continueno action required• identifi cation of escaperoutes and emergencyexits• fi rst aid and rescuestationsbluespecifiedmeaningspecifiedmeaning• display of necessityfor specifi ed action• command sign• notice• machine-specific• action• protection• extraordinary attention• safety-relevant regulationor precaution with priorityspecifi ed action• obligation to wear personalprotective equipment• location of a telephone• etc.white /clearotherneutralneutralnot assigned anyparticular meaning23
