Maintenance and Inspection Maintenance Instructions• Be sure to turn OFF the system to stop laser emission before cleaning the system.• Molded resin is used in some parts of the system. Do not use organic solventssuch as paint thinner or benzine to wipe the dirt on the system.• Do not wipe the glass portion of the laser aperture too strongly. Scratches on theglass may cause measurement errors.(1) Cleaning Emitter and Receiver on Front Side of Sensor Head• Always keep the emitter and receiver of the sensor head clean. Make sure that theemitter and receiver are free of substances that refract light, such as water, oil, orfingerprints, or surface water, or matters that block light, such as dust and dirt.Inspect the surfaces regularly and always keep them clean.• Blow away large particles of dust, if any, using a camera lens blower.• To remove small particles of dust or fingerprints, use soft lens cleaning cloth orlens cleaning paper and lightly wipe them out.• Use cloth moistened with a small amount of alcohol to wipe out tough dirtcarefully. InspectionInspect the system regularly to maintain the performance of the system and make itpossible to use the system under optimum conditions.● Major Inspection Items• Check that no I/O terminal connections are loose or disconnected.• Check that the glass surface on the laser aperture is free of dust, dirt orfingerprints.• Check that the power supply voltage is within the rated range (21.6 to 26.4VDC).• Check that the operating ambient temperature during use is within thespecification range (a sensor head temperature range of -10°C to 45°C).• Check that operating ambient humidity (RH) is within a range of 35% to 85%.Ramco National800-280-6933 | nsales@ramcoi.comwww.panasonicsensors.com
