Instruction ManualNivuMaster Ultrasonic Sensors®NivuMaster Ultrasonic Sensors - Rev. 06 as of 29.07.2011 Page 278 TroubleshootingError Possible Reason CorrectionSensor error Connection Check connection at terminal clamp.Sensor installation Check installation. Risk of echo loss as soon as thesensor position is at an angle to the reflecting surfaceor in a place tending to foam/wave formation.Projecting edge Check installation. Risk of faulty measurement if thesensor is in a position where (a) projecting edge(s)cause additional reflections.Transmitter Check supply voltage9 Table of ResistivenessThe NivuMaster sensors are resistant to normal domestic sewages, dirt and rainwater as well as mixed water from municipalities and communities. The sensorsnevertheless are not resistant to all substances and substance mixtures.As a basic principle, damage might occur in case of using chloride mediaas well as various organic solvents!Please observe that substance mixtures (several substances being present sim-ultaneously) under certain circumstances may cause catalytic effects whichmight not occur if the individual substances are in use. Due to infinitely possiblecombinations these catalytic effects cannot be verified entirely.10 Maintenance and CleaningDuring standard use the NivuMaster sensor does not get in contact with themeasurement medium and therefore is virtually maintenance-free. If the sensorface however should get dirty due to medium contact (immersion) or ambientconditions (dust) clean the sensor face carefully with a damp cloth.Never use aggressive cleansing agents (such as thinner). For heavy pollutionNIVUS recommends the use of surface-active agents. The use of abrasivecleansing agents is not allowed.If you wish to clean or dismantle the sensor please disconnect the unit frommains before.No hard objects such as wire brushes, rods, scrapers or similar shall be used toclean the sensor. Using a high pressure cleaner may lead to sensor damageand measurement failures and thus is not allowed. |
