Under Range Indicator in Chapter 6 See Technical Specification for a complete list of Under Range triggering points Overload Condition An overload condition occurs when either the peak signal starts to exceed the signal handling capability of the specialised amplifier circuitry or if the vibration level exceeds the top of the selected range by 596 If the vibration source saturates the input circuitry or is 596 greater than top of the selected range an Overload condition occurs and an overload indicator is displayed on your instrument If an overload condition occurs it is highly recommended to change to a higher range with a lower sensitivity as your meter will be out of specification The overload indicator will remain on for a minimum of 2 seconds or while the overload condition remains Please be aware that the selected frequency weighting may attenuate the displayed signal level below the overload triggering point but an overload can still occur This is because the overload operates from the unweighted input signal Placement of the overload indicator can be found under Overload Indictor in Chapter 6 See Technical Specification for a complete list of Overload triggering points Page 24 Chapter 4 Getting Started The AVIO16S instrument has three states of basic operation e Stop State e Record State e Playback Whilst the instrument is in the Record State the vibration activity is analysed and all parameters

16. Analysis The next step of your predicitive maintenance program after detecting any machinery complications will be to identify the problem with the machine It may be necessary to use more specialized monitoring equipment to determine the vibration signature of the fault and exactly pinpoint the location however if as discussed vibration readings are recording in all three directions 1 Axial 2 Radial Horizontal 3 Radial Vertical Then this maybe be sufficient data to determine the more common machinery problems and there location Correction The last stage of the predicitive maintenance program after detection and analysis will be to correct repair the found problem With early detection and analysis the correction can be planned in advance for a convienent time to ensure minimum disruption and minimum cost Page 23 Under Range amp Overload Conditions Under Range Condition An under range condition occurs when the vibration level is equal to or lower than the bottom of the current range the meter is set to If this condition occurs then the Under Range indicator will be displayed on your instrument In such circumstances it is highly recommended to change to a lower range with a higher sensitivity as your meter will be out of specification The under range indicator will remain on for a minimum of 2 seconds or while the under range condition remains Placement of the under range indicator can be found under

49. with a rechargeable battery pack featuring the latest NiMH technology which incorporates extremely low self discharge Every part of the HAAVI has been thoughtfuly designed The case accelerometer and cable are all rugged for industrial use and the meter is extremely easy to use with a simple three button operation all you virtually need do is press the power button and start recording With the AVID16S machine monitoring has become even easier Page 14 Chapter 2 Accelerometer Type Removal and Fitting The accelerometer for use with the AVIO16S produces a Voltage Output proportional to the signal being measured The table below shows the output voltage and specifications for the accelerometer where g is the acceleration due to gravity on the Earth s surface and is defined as 9 80885 ms Acceleration is measured in metres per second per second m s s which can be written as either of the following Accelerometer Type HVM116 Single Axis Accelerometer Accelerometer Output Operating Frequency Type Voltage Range Response Single Axis 100mV g 20g 2 to 10000Hz 10 HVM116 Single Axis Accelerometer Page 15 Attaching amp Removing the Accelerometer Locate the jack socket on the instrument and gently push the 3 pole jack plug of the accelerometer cable into the jack socket To remove the accelerometer cable from the instrument gently pull the jack plug from the instrum
50. with the machine mounting or the structure of the machine itself Axial vibration travels in either direction along the shaft Bent shafts or misalignment of bearings or the shaft coupling device can cause higher machine vibration measurements Ensure flanges are not overloaded to reduce the chance of misalignment issues To measure the correct direction mount the accelerometer so that the resulting vibration travels up through the accelerometer Page 20 The severity of the vibration level measured will be proportional to any amount of misalignment imbalance or bending of the shaft Remember Condition Monitoring you need to devise a regular monitoring schedule for your machinery that enables you to ascertain and repair many costly machine faults before they occur Your AVIO16S instrument is a tool to aid in this condition monitoring it is not a tool that gives detailed fault analysis by using techniques such as fast fourier transforms Used correctly with trained personnel it will give a good early indication as to where faults may be occurring and allow you to plan scheduled corrective maintanence It is then down to the experience of the engineers to determine and repair the fault or if required analyse the vibration fault even further using specialsed monitoring equipment to determine the exact location of the problem Page 21 Predictive Maintenance Program In general your vibration predictive maintenance program
