Technical description 7 1 Technical description Sebalog N-3 is a system for acoustically monitoring pipe systems. It has Log N-3 noise level loggers and the Commander-3 as its basis. The Commander is used for programming the loggers as well as reading out and analysing the recorded measurements. To monitor a zone, you can attach as many noise level loggers along the pipe as you wish. They then perform regular noise measurements within a certain time window. The user can set the exact measurement time window and other parameters before measuring begins. The level and frequency of the individual measurements are saved in the logger. Even the quietest noise is saved as an audio recording. After measuring, you can collect the loggers, call up the readings and check for leak noises, and then put them back in a new zone, for example. This allows all the zones in a pipe system to be checked in succession for leaks. However, the loggers can also be left in the same zone to monitor it permanently. The measurements from the individual loggers are then read out on site. Just approaching the installed loggers with the Commander or another reader will suffice. Wireless data transfer takes place automatically. Ideally, all you have to do is drive by where the loggers are being used. The Sebalog N-3 system has the following features: • Loggers can be used temporarily, permanently or in the network • Wireless communication between all components • Audio data recorded directly in the logger • “Commander-3” with colour display, USB port, large memory capacity, and much more. • Complete group/logger management without a PC • History function • Extended wireless range using repeater • Logger available as TNC version with external antenna Function Features
Technical description 8 The Sebalog N-3 system consists of the following components: Component Use Log N-3 noise loggers measures regularly the volume level and frequency of the noise in the pipe during the programmed measuring window. Commander-3 is the portable device for programming the loggers before measuring, and for reading out and analysing the recorded data after measuring. Repeaters-3 forward the radio signals from the loggers and therefore extend the wireless link between the loggers and Commander. GSM box-3 is used as the interface between the logger network and control centre during wireless remote data transmission. SebaDataView-3 software is the application software for programming the loggers before measuring, and for reading out and analysing the recorded data with a PC or laptop. Reader-3 is a convenient device for reading out the measurements taken by the Sebalog series of loggers. Log RI is used as the wireless interface to the loggers or repeaters when connected to a PC/laptop. Components

Important and common terms 13 2 Important and common terms The Commander-3 can be operated in two different user modes (see page 23): • Easy mode • Professional mode You can switch between these modes in system settings menu (see page 25). These two values are identified each time a noise logger performs a measurement: • “Level” … is the noise level (volume) of a measurement • “Frequency” … is the frequency in the measurement’s frequency spectrum with the greatest deflection ESA stands for “Extended Spectral Analysis” and means that noise level and frequency are combined in one reading using a mathematical formula. This results in an extended view of the measured data, which makes the leak probability and position visible in relation to other loggers. The dimensionless ESA value can be between 0 and 100. The higher the ESA value, the higher the leak probability and the shorter the distance from the logger to the leak. In order to analyse the recorded measurements, the noise loggers must be read after measuring, i.e. the data in the loggers is accessed wirelessly with a reading device (Commander/Reader/PC). It is possible to do this in the following ways: Group mode “Lift&Shift” “Patrol” “Network” The loggers are collected; data is read out wirelessly in the office The loggers remain at the place of use; data is read out wirelessly while “driving by” All the installed loggers are networked with each other and connected to a GSM box; data is read out via mobile radio from the office The method must be chosen for reading out the measured data before the measuring work is performed. Before measuring, the mode decided on is permanently assigned to the loggers or logger groups. After that, only loggers that have been configured for reading using “Patrol” can be read with “Patrol”, for example, and not with “Lift&Shift” or “Network”. The same applies to the other group modes. User mode Level and frequency ESA value Group mode
Important and common terms 14 The Commander can only ever interact with a single registered logger group. This group is called the “workgroup”. It is not possible to program or read loggers from another group. The “measuring window” is the time during which a logger is programmed to carry out measurements, e.g. from 2 a.m. until 4 a.m. in the morning. A measuring window could also be referred to as a “measuring day”. A measuring period refers to the time span that passes between programming and reading a logger. A measuring period can therefore last 1 to 100 measuring days. There is a certain basic noise level in each pipe system. This basic noise level is referred to as the “leak threshold”. This level may be known or estimated based on experience. If the lowest measured noise level in a section of pipe is above the leak threshold, there is presumed to be a leak. If the level of the quietest noise in a measuring window is above the previously found leak threshold (see above), the logger goes into “leak status”. This means, for example, that when this logger is read, a warning appears on the reader indicating that there is an increased probability of a leak close to the logger. The term “leak value” combines the three measurement results – level, frequency and ESA value – determined for the quietest noise in a measuring period. If a noise logger has been switched off (i.e. it has stood “on its head” for at least 3 minutes), it is in “configuration mode” after it is switched back on. This means: • The previous programming has been deleted. The logger is now unprogrammed. • Switching off has not deleted the previously saved measurement results. They are still in the logger’s memory and can be accessed by a reading device, but only by single interrogation (see page 54). • The logger is ready for wireless operation and waiting to be contacted by the Commander or PC. The logger remains in configuration mode until it is reprogrammed. Each device in the Sebalog N-3 series has a unique serial number (SN). You will find it on the type plate of the device. All loggers, repeaters and GSM boxes also have an identification number (ID) which can be used by the Commander or the SebaDataView software to manage them. You will also find the ID on the type plate, or on a separate plate on the device. The identification number is identical to the last six digits of the serial number. When inputting an ID, the preceding zero digits can be omitted. Thus, if the ID is “000815”, you need only enter “815”. Workgroup Measuring window Measuring period Leak threshold Leak status Leak value Configuration mode Identification number
The loggers 15 3 The loggers 3.1 Function The noise loggers are installed along a section of pipe directly on the pipe, or directly on fittings on the pipe. Within the configured measuring window, they perform regular noise measurements, each 3 seconds in length. The volume level and frequency of each measurement are saved in the logger. While the noise level alone only records the general existence of a leak, together with the frequency it also provides information on the approximate distance in relation to other loggers. The measurement results gathered by the logger can be queried later using a reading device (Commander/Reader/PC). The quietest noise of the last measuring window is saved as an audio file. After reading out the data, you can actually listen to the assumed leak noise and immediately decide if it is a leak noise or background noise. The “Real time measurement” function can be used to observe a logger “live” as it measures (see page 58). With the “Direct recording” function can be used to listen to a noise in a pipe (see page 63). Communication with the loggers is performed with short range radio only.
The loggers 16 3.2 Design All noise loggers have a highly sensitive microphone with a large dynamic range, a data memory and a lithium battery inside. The standard loggers also have an internal radio antenna. The loggers have the following external characteristics: Element Description Hole (M5 thread) For fitting the supplied ring, which can be used for carrying the logger and pulling it out of the shaft. Label with identification number (ID) Each logger has its own six-digit identification number. Type plate The last six digits of the serial number (SN) on the type plate of the device are identical to the ID. Marking Must always face upwards when the logger is fitted horizontally. Magnetic foot Can be unscrewed and replaced by an adapter, or similar, from the assembly accessories. The special TNC version of loggers have no internal antenna. Instead of the hole for the assembly ring they have an antenna socket for connecting an external antenna. Introduction Standard version TNC version “Head” of the logger “Foot” of the logger
The loggers 17 3.3 Switching on and off The noise loggers have an internal tilt switch and are switched on and off simply by turning them over. Loggers standing on their foot are switched on. Loggers standing on their head for longer than 3 minutes are switched off. Each time a logger is switched on, its configuration data is reset to the default values. The time internally is also lost. Therefore, whenever the logger is switched back on, it must be reprogrammed (see page 50). 3.4 Memory A logger’s internal memory allows a maximum of 100 pairs of values (the level and frequency of a measurement) to be recorded. Furthermore, the quietest recording of the last measuring window is saved as an audio file (3 seconds in length). Circular buffering is used, with the oldest stored measuring window being deleted after 100 measurements. 3.5 Power supply Each logger has an internal lithium battery. The actual battery lifetime depends on the intensity of use. If a logger is always operated using the default configuration data, factory-set in the Commander, a battery lifetime of up to 5 years is possible. Longer measuring periods and increased wireless activity/availability shorten the life of the logger battery. Severe fluctuations in climatic conditions also have a negative impact. Flat batteries cannot be recharged. They must be replaced. SebaKMT or an authorised service partner must change the batteries. Otherwise, water- and dirt-resistance of the logger cannot be guaranteed.
The Commander 18 4 The Commander 4.1 Function The Sebalog Commander 3 is the mobile programming and reading device for noise loggers in the Sebalog N-3 series. The Commander is used to program the noise loggers before measuring. After measuring, the recorded data in the loggers can be queried with the Commander. Both current and older data can be displayed on the device’s screen and analysed in greater detail. Furthermore, a real time measurement can be performed (see page 58). After connecting the supplied headphones, you can play back audio files of leak noises. It is also possible to listen to the current noise in a pipe (see page 63).
The Commander 19 4.2 Device design The Commander has the following controls and connections: Element Description Selector knob ESC button I/O button • Device on/off • Backlight on/off Charging indicator light • Lights up red … external supply, battery is being charged Socket for USB link to PC and for connecting an optional GPS module (combined) Headphone and charging socket (combined) Antenna socket Controls and connections
The Commander 20 4.3 Design of the user interface All the menu levels on the Commander’s user interface consist of a large display area and an infobar on the bottom edge of the screen. The content and structure of the display area change depending on the system status. In Easy Mode, the main menu can be selected in the display area of the start screen. In Professional Mode, the “Main menu bar” is between the display area and infobar. You can access the individual functions of the device using the symbols shown. Quick start for reading out the measured data of the workgroup Functions for programming and reading loggers Functions for displaying, playing back and analysing data, etc. Functions for managing loggers in the Commander, etc. Back to the next higher menu level The infobar structure remains the same in each menu and continuously provides the user with the following information (from left to right): • A help text gives short explanations on the selected element or on how to proceed further. • A coloured symbol indicates the group mode (see page 13) of the workgroup … “Lift&Shift” … “Patrol” … “Network” • The battery symbol indicates the charge level of the battery. • The Commander’s internal time. Main menu Infobar N P L Display area Infobar Help text ++ Help text ++ Help text Main menu bar (Professional mode only)
The Commander 21 4.4 Basics of operation The Commander is very simple to operate and intuitive in principle. Navigation within the menus is done exclusively with the aid of the selector knob as follows: Turning = select Pressing = open/confirm (ENTER function) The selected element appears on a black background: In Easy Mode, use the ESC button to exit each menu. This immediately returns you to the start screen. Any functions started are cancelled. In Professional Mode, you can use the symbol at any time to return to the previous menu level. Pressing the ESC button once makes the hidden main menu bar reappear. Pressing it a second time takes you back directly to the start screen. With the aid of the selector knob, not only can individual menu items be accessed but also settings can be changed and parameters adapted. Please proceed as follows: select element → ENTER → change parameter → ENTER In some cases, the parameter can be changed directly in the input field. In others, a pull-down list opens where you can select a new setting. Navigation within the menus Exiting the menu Adjustable parameters If in doubt, you can always cancel a procedure with the ESC button. 20 20 5 5 Selected Not selected
The Commander 22 To input comments or similar, a virtual keyboard appears on the screen, which is also operated with the selector knob. … deletes last character … switches between upper- and lower-case … inserts space … confirms and completes input Various menus list the individual loggers of a logger group. This appears in a table-like form. You are able to re-sort these loggers by the criteria “Comment”, “Time of data read-out” or “ESA value”. This can be useful for identifying certain loggers straightaway, e.g. all loggers where a leak is suspected, etc. To change the sort, apply the Sort button repeatedly. A small triangular symbol in the header of a column indicates which criterion is selected and whether the loggers are arranged in descending ▼ or ascending ▲ order. Examples of possible settings: “ESA ▼” … sorting by ESA value (descending), i.e. the loggers with a suspected leak are at the top of the list “Date/time ▼” … sorting by time of the data read-out (descending), i.e. the loggers most recently read are at the top of the list “Date/time ▲” … sorting by time of the data read-out (ascending), i.e. the loggers not yet read are at the top of the list Various functions require the identification numbers (IDs) of loggers, repeaters or GSM boxes to be given. When inputting an ID, all the preceding zero digits can be omitted. Thus, if the ID is “000815”, you need only enter “815”. Virtual keyboard Sorting loggers Entering an identification number
The Commander 23 4.5 User mode The Commander-3 can be operated in two different user modes. Easy mode Professional mode In Easy mode all the main functions of the device are available. They can perform most day-to-day work quickly and simply - from programming a logger group to analysing measured data on the Commander. The individual applications are structured very clearly; the user is partly guided step-by-step from one action to the next. Easy mode is therefore not just suited to first-time users but also experienced operators who prefer to use its simpler menu structure. In Professional mode all the functions of the device are available to the user. This allows the system to be better adapted to the user’s requirements and conditions on site. Difficult measurements can be prepared more exactly and the results evaluated and documented in more different ways, etc. Some applications can only be used in Professional mode, such as using Repeaters or building a logger network. If the Commander is in Easy mode, the following symbol is permanently displayed above the infobar: If the EasyGo symbol isn’t shown on the screen, the Commander is in Professional mode. The user mode can be switched in the system settings (see page 26). Introduction How to identify the user mode? How to change the user mode?
The Commander 24 4.6 Making a connection 4.6.1 Connection between the Commander and logger Short range radio is used for communication between the Commander and loggers. The Commander has an integrated radio module. After the antenna is connected (standard or vehicle antenna), the device is ready for wireless operation. The loggers must be switched on and wirelessly available (see page 52). The radio range of a logger is affected by the conditions where it is used. To extend the range a repeater can be used (see page 64). 4.6.2 Connection between the Commander and PC The connection between the Commander and a PC/laptop is made using the VK 77 connection cable supplied and is needed for the following tasks: • Transferring measured data from the Commander to the PC. • Transferring configuration data from the SebaDataView-3 software to the Commander. • Installing a firmware update on the Commander. The Commander must be operated in Professional mode to connect it to the PC. Proceed as follows: Step Description 1 Select the button in the main menu bar. 2 In the next menu, select the Connect to PC button. 3 Use the USB socket on the Commander for connecting the cable to the PC. Markings on the plug and socket ensure that the plug is lined up correctly. You must feel the plug engage. 4 Select the Connect button on the Commander. Result: The connection is made. The Commander is automatically detected by the PC as a mass storage device. As soon as the Connected message on the Commander’s screen appears, data can be transferred between the Commander and PC. If no connection is made, check the cable connection again. If necessary, disconnect the Commander from the PC, restart it again, or perform a reset, and follow steps 1 to 4 once again. To end the connection, select the Disconnect button on the Commander. As soon as the Disconnected message on the Commander’s screen appears, the connection cable can be removed. Purpose Making a connection Disconnection
The Commander 25 4.7 Switching on the display lighting The Commander’s screen has a backlight. It is activated by using the selector knob or briefly pressing the I/O button . The lighting then remains on for a certain time period. The length of this period (a maximum of 4 minutes) can be adjusted in the system settings (see page 26). 4.8 System settings You can use the System settings menu to customise various device settings to the needs of the user. Beginning at the start screen, follow the  symbols. The System settings menu opens: When the Commander is in Professional mode, more settings can be changed than in Easy mode. Use the Next button to go to the second page of the menu.
The Commander 26 4.8.1 Basic settings The following basic settings can be made in both Professional mode and Easy mode: Line Description User mode Select a user mode for the device (see page 26). Language Select a language for the user interface. If you cannot read the preset language, you can go to the language selection - starting from the main menu - via the following symbols:   Time and date settings In the Timezone line, select the timezone for where you are. In the Daylight saving time line select whether it is currently winter or summer time. In the Date format line, select the date format to be used by the Commander. DD … Day MM … Month YYYY … Year In the Time line, enter the current time for the Commander (hour:minutes:seconds). In the Date line, enter the current date for the Commander (day:month:year). Backlight switch off Select a period of time for the backlight until it is switched off automatically (never = continuous backlight). Turn off autom. after Select a period of time for the auto-off function. If no entry is made for longer the specified time, the Commander switches off automatically (never = automatic switch off deactivated). Keybeep Activate/deactivate the key tone that sounds when the selector knob is pressed. History Activate/deactivate the “History” function. If the “History” function is activated, the measured data from loggers remains stored in the Commander after they are read out. They can then be called up at any time and displayed again. If the function is deactivated, the previous data set is overwritten when new data is read. Deactivating the function can be useful because this saves memory space and the Commander can work faster in certain situations.
The Commander 27 4.8.2 Extended settings in Professional mode The following extended settings are only available in Professional mode: Line Description Logger list visibility Select table columns to be shown/hidden. Various menu levels list the loggers of a group in a table on the screen. The columns contain information about the loggers, such as the logger ID and logger comment. To make the table clearer, you can specify which columns are actually shown. Logger found beep Switch the acoustic signal on/off that occurs when a logger is found. An acoustic signal sounds each time the Commander detects a logger when reading out data. A corresponding message is shown briefly on the screen. When “patrolling”, this can happen several times in succession because the loggers send data packets to the Commander at regular intervals. You can specify how often there is a signal or a message: • always … acoustic signal each time the Commander detects a logger • only once if logger found … acoustic signal only when a logger is detected the first time • never … no acoustic signal • beep and display only once … acoustic signal and message on the screen only when a logger is detected the first time Additional hints Decide if additional information shall be shown or not. At various positions in the menu, special displays appear on the screen, providing additional information about the current functions. These displays can be deactivated. Sorting order Select the standard sorting order for loggers in tables. Various menu levels list the loggers of a group in a table on the screen. The criterion by which the loggers are sorted within the table as standard can be specified.. Factory settings Restore factory settings. The settings on the Commander can be reset to the factory settings, to the state when the Commander was delivered.
The Commander 28 4.8.3 System info When the Commander is operated in Professional mode, the System settings menu has the following information on the device and the firmware currently in use: Line Description Free space Commander’s free memory space in MB Software version Firmware version of the Commander Software date/time When the firmware was last updated ID Identification number of the Commander 4.8.4 Saving settings To save any changed settings in Easy mode, apply the OK button before exiting the System settings menu with the ESC button . In Professional mode, saving is automatic when exiting the menu. 4.9 Performing a hardware reset If the Commander stops responding to inputs (from the selector knob or buttons), a hardware reset can be performed. Hold down the selector knob and the ESC button at the same time for about one second. The Commander restarts automatically. This usually rectifies the malfunction. If the malfunction persists after this normal reset, try the following: Hold down the selector knob and the ESC button at the same time for about three seconds. The Commander switches off. Wait about a minute before switching the Commander back on with the I/O button . The device should now function correctly again.
The Commander 29 4.10 Updating the firmware Visit regularly the Downloads section at www.sebakmt.com for information about new versions of firmware. You can install any updated versions of the firmware on the Commander if they are available. The current version of the Commander firmware installed can be found in the system settings (see page 28). To update the firmware, proceed as follows: Step Description 1 First ensure that the Commander’s battery has sufficient power to update the firmware (at least one bar on the battery symbol on the infobar (see page 20)). If in doubt, recharge the battery first (see page 30). 2 Download the latest firmware archive from www.sebakmt.com and extract it to a directory on your PC. 3 Connect the PC and Commander together via USB- (see page 24). 4 Copy the extracted files directly into the Commander’s main directory. 5 Disconnect the Commander from the PC (see page 24). 6 Switch the Commander off and then on again, or perform a reset (see above). Result: The firmware update begins. A bar indicator shows the progress on the screen. CAUTION During the update, no entries whatsoever must be made on the Commander! This could cause the device irreparable damage. After the procedure is complete, the device switches back on automatically. Check the version number in the start screen to see if the Commander is actually using the new firmware.
The Commander 30 4.11 Memory The Commander has a 2 GB internal memory. This is sufficient to manage the data of up to 1,000 logger groups, each with 1,000 loggers. You can query the available memory space at any time in the system settings (see page 25). 4.12 Power supply The Commander is fitted with an internal Li-ion rechargeable battery. This can power the device for approximately 20 hours. The battery’s present charge level is shown continuously by the battery symbol in the infobar on the screen. If the battery is low, a warning on a coloured background appears on the screen: • Yellow background … device can still operate for a few hours • Red background + warning sound ... device will shortly switch off The Commander can be operated using an external electricity source. Connect it to the mains voltage or to your vehicle’s 12 volt socket. A guide on the round plug of the charging cable and a groove on the charging socket of the Commander specify the correct alignment of the plug. As soon as the Commander is connected to the external power supply, its battery is charged up automatically. This is shown by the red charging indicator light and by the arrow in the battery symbol at the bottom right of the screen. Charging takes approximately 12 hours. The battery is fully charged once four bars are shown in the battery symbol. After the battery is fully charged, the Commander switches to trickle charging. CAUTION During charging, the ambient temperature should be between 10°C and 40°C (50°F and 104°F). Otherwise the device could be damaged! Only use the supplied charging cable to connect the Commander to external power sources. If you experience problems with the battery, please contact your SebaKMT sales partner. Do not open the device yourself. The stated water- and dirt-resistance can only be guaranteed if any work on the device is performed solely by service departments authorised to do so. The Commander automatically switches off if no input is made within a specified time period. This timespan can be configured in the system settings (see page 26).

The Easy mode main menu appears on the screen: In Easy mode, the symbol is continuously shown at the bottom of the screen. If you do not see this symbol, the Commander is in Professional mode. To switch to Easy mode, open the system settings menu. Starting from the start screen, follow the  symbols and, in the first line of the menu, select the “Easy mode” setting from the list. The screen might not be displaying the correct language. The language can be changed in the system settings menu. Beginning at the start screen, follow the   symbols and select your language from the list. 5.1.2 Checking the basic settings Before a measuring session, check that the Commander’s system settings are up-to-date and correct (see page 26). The date and time settings in particular must be correct. Beginning at the start screen, follow the  symbols to open the system settings menu. Changing the user mode Changing the language Name of the workgroup System date
Working in Easy mode 32 5.1.3 Defining a workgroup More than one group of loggers can be registered in the Commander. However, the Commander can only work with one of these groups at a time. This group is called the “workgroup”. Specify the workgroup for the impending measurement session. Please proceed as follows: Step Description 1 In the main menu, select the System settings button. 2 In the next menu, select the Change group button. Result: A list with all the registered logger groups opens. The current workgroup is indicated by an X. 3 Select a logger group for the measurement session. Result: The selected group is now registered in the Commander as the workgroup. In the main menu, the name of the workgroup is shown at the bottom left of the display area. Each logger group in the list has already been assigned its group mode (see page 13). Groups with an “L” before the name can only be read using “Lift & Shift”, i.e. all the loggers in the group are collected and then read together. Groups with a “P” before the name can only be read using “Patrol”, i.e. all the loggers in the group remain in the shaft and are read on location individually. The loggers of a group with an “N” before the name are networked together and connected to a GSM-Box. These loggers can’t be read by a reading device but send their data regularly to a FTP server.
Working in Easy mode 33 5.2 Programming the loggers The loggers in the workgroup must be reprogrammed before each session. This means that the Commander sends basic data for the session wirelessly to the loggers (e.g. the measuring window). To program the workgroup proceed as follows: Step Description 1 In the main menu, select the Prepare loggers button. Result: The workgroup is shown. The name of the group is at the very top of the display, and all the loggers in the group are listed underneath. 2 Select the Prog. Group button. Result: The next step is shown. 3 Switch off all the loggers in the group, i.e. place them “on their head” for about three minutes. As an aid, a three-minute countdown on the screen can be started with the Start button. Then select the OK button. Result: The next step is shown. (continued on the next page) Introduction Procedure
Working in Easy mode 34 Step Description 4 Switch on all the loggers in the group, i.e. place them “on their foot”. Select the OK button to confirm. Result: The next display provides information about the data used to program the loggers. (It is not possible to change this configuration data in Easy mode). 5 Select the Program button. Result: The next display opens and the Commander automatically begins transferring data to the loggers. The flashing antenna symbol on the bottom left of the display area indicates that the data transfer is in progress. The left-hand window shows all the loggers in the group already programmed. The right-hand window contains all the loggers with which no contact has yet been possible. The Stop button can be used to cancel programming at any time. It can be recommenced with the Start button. The procedure ends automatically once all the loggers in the group have been successfully programmed. The loggers are now ready to be installed for use on location. Use the ESC button to return to the main menu. From now on, do not place the loggers on their head because switching off would cause them to lose their configuration data and they would need to be reprogrammed. If a logger could not be programmed, it may be because it was not in “Configuration mode” at the time of programming, (see page 14) i.e. it had not been properly switched off and switched back on 3 minutes later. It is also possible that the logger is not within the wireless range of the Commander. The ideal distance between a logger and the Commander is about one meter. Possible sources of error
Working in Easy mode 35 5.3 Installing the loggers Install the loggers of the workgroup in succession along the stretch of pipe. It is best to fit them directly on the pipe. However, you can also attach the loggers to valve rods or hydrants, for example, or any other position along the pipeline that is easily accessible. There must be the best possible contact between the logger foot or the mounted adapter (see below) and the pipe. If the logger is attached to a valve rod, for example, make sure the surface is as flat as possible. Clean the rod thoroughly (preferably with a wire brush). Due to their powerful magnet, the loggers can also be attached horizontally to ferromagnetic surfaces. You must however make sure the red mark on the logger is facing upwards. Otherwise the internal tilt switch will switch the logger off after 3 minutes. Loggers with the mark facing upwards are switched on. Loggers with the mark facing downwards are switched off. If the logger cannot be attached anywhere directly, the accessories for the Sebalog N-3 set have various adapters. If, for example, the surface of the valve rod is not flat, or not magnetic, unscrew the magnet on the foot of the logger and fit the 20 mm or 42 mm valve rod adapter (optionally available) instead. When installing the logger on an underground hydrant, you can fit it on the valve rod or on the side of the rod, depending on the height of the shaft. Use the magnetic angle adapter, for example, for side mounting. For underground hydrants with bayonet fittings, you can use the underground hydrant adapter. Fit the adapter in the hydrant claw. For plastic domestic pipes (water meter fittings), use the plastic fitting, if necessary in combination with the angle adapter. Basics Horizontal installation Special cases
Working in Easy mode 36 The following pictures show a few methods for installing N-3 noise loggers: Logger on the valve rod of an underground hydrant Logger on an underground hydrant Logger with an angle adapter on the valve rod Logger with an angle adapter on the hydrant claw Logger with an angle adapter horizontally on the valve rod Installation examples
Working in Easy mode 37 5.4 Reading out the measured data After the loggers have been installed on location for at least one measuring day, the recorded measured data can be read out with the Commander. The exact same group mode (“Lift&Shift”/“Patrol”/”Network”) for which the workgroup was programmed is used. Groups with an “L” before the name can only be read using “Lift & Shift”, i.e. all the loggers in the group are collected and then read together. Groups with a “P” before the name can only be read using “Patrol”, i.e. all the loggers in the group remain in the shaft and are read on location individually. The loggers of a group with an “N” before the name are networked together and connected to a GSM-Box. These loggers can’t be read by a reading device but send their data regularly to a FTP server.
Working in Easy mode 38 5.4.1 Reading out a “Lift&Shift” group To read out the measured data in the loggers, proceed as follows: Step Description 1 Collect up all the loggers of the group and place them next to the Commander. Avoid placing the loggers on their head! The stored data would not be lost if the loggers were switched off, but it would no longer be indicated if a logger is in leak status or not (see page 14). 2 In the main menu of the Commander, select the Readout loggers button. Result: The Commander and the loggers are connected. Data transfer begins automatically. The antenna symbol in the bottom left of the display flashes. As soon as the Commander detects a logger, it receives its measured data. The corresponding logger switches from the right-hand to the left-hand window on the screen. The coloured background of the read data in the left-hand window reflects the probability of a leak. No colour … Leak probability low, leak threshold was not exceeded Grey … Leak probability not available, logger in configuration mode (was switched off during or after the measurement) Other colour … Leak probability high! Leak threshold exceeded! The colour reflects approximately the frequency of the leak noise: Blue Yellow 0 Hz 2,500 Hz If a logger’s comment is on a red background, this means that its battery is weak. 3 The Stop button can be used to cancel reading at any time. It can be continued with the Start button. The procedure finishes automatically once the Commander has received and saved the measured data from all the loggers in the group. If a logger could not be read, it may have been switched off, not ready for wireless operation or it was outside the Commander’s wireless range. 4 You can immediately view the data of a logger that has just been read. To do so, select the left-hand window on the screen and then select the respective logger. Result: The logger’s measured data is shown (see page 42). Use the ESC button to return to the main menu.
Working in Easy mode 39 5.4.2 Reading out a “Patrol” group To read out the measured data in the loggers, proceed as follows: Step Description 1 In the main menu of the Commander, select the Patrol Loggers button. Result: The Commander is ready to receive the measured data from the individual loggers. The antenna symbol in the bottom left of the display flashes. 2 Move into the wireless range of each logger one after the other. If the radio signals of the loggers are strong enough, the data can also be collected while in the car, simply by driving past where the loggers are installed. The Commander’s standard antenna can be replaced with the supplied vehicle antenna to do this. As soon as the Commander has detected a logger, the following message appears on the screen: Logger comment Logger ID Level/frequency of the quietest noise in the measuring period The message has a coloured background. The colour shows straightaway whether the programmed leak threshold has been exceeded or not during the measuring period. • Yellow … Attention! Leak threshold exceeded! • Blue ... Leak threshold not exceeded There is an acoustic signal along with the message: • Long tone ... Attention! Leak! • Short tone … No leak As standard, the tone sounds each time a logger is detected. It can be deactivated in the system settings of Professional mode (see page 27). If the displayed message contains a battery symbol, this means the battery of the particular logger is weak. If the displayed message contains a clock symbol, this means the logger’s internal clock differs from the system time of the reading device by more than 30 minutes. The logger group concerned should be reprogrammed. The logger’s clock is synchronised with that of the Commander. It is only possible to change the time of individual loggers in Professional mode. (continued on the next page)
Working in Easy mode 40 Step Description The detected logger switches from the right-hand to the left-hand window on the Commander screen. The coloured background of the read data reflects the probability of a leak. No colour … Leak probability low, leak threshold was not exceeded Grey … Leak probability not available, logger in config. mode, (was switched off during or after the measurement) Other colour … Leak probability high! Leak threshold exceeded! The colour reflects approximately the frequency of the leak noise: Blue Yellow 0 Hz 2,500 Hz If a logger’s comment is on a red background, this means its battery is weak. 3 The Stop and Start buttons can be used to cancel and continue reading at any time. The procedure finishes automatically once the Commander has received and saved the measured data from all the loggers in the group. During “Patrolling”, the complete measured data set is only transferred to the Commander from loggers in leak status (see page 14). To save power, if the quietest noise in a measurement is below the programmed leak threshold, the loggers will only send a small packet to the Commander, with the level and frequency of this noise. If necessary, the complete measured data of these loggers can be called up using single interrogation in Professional mode (see page 54). If a logger could not be read, it may have been switched off, not ready for wireless operation or it was outside the Commander’s wireless range. 4 You can immediately view the data of a logger that has just been read. To do so, select the respective logger in the left-hand window on the screen. Result: The logger’s measured data is shown (see page 42). Use the ESC button to return to the main menu.
