Technical description 1 Technical description Function 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.
Technical description Components 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.

Important and common terms 2 Important and common terms User mode 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).
Important and common terms Workgroup 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. Measuring window 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”.
The loggers 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.
The loggers 3.2 Design Introduction 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. Standard version The loggers have the following external characteristics: “Head” of the logger “Foot” of the logger 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.
The loggers 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.
The Commander 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).

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”.
The Commander 4.5 User mode Introduction 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.
The Commander 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.
The Commander 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.

The Commander 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.
The Commander 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: 4.8.
The Commander 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).
The Commander 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 Internal supply The Commander is fitted with an internal Li-ion rechargeable battery. This can power the device for approximately 20 hours.
Working in Easy mode 5 Working in Easy mode 5.1 Starting up the Commander 5.1.1 Switching on the Commander Switch on the Commander by pressing the I/O button . The Easy mode main menu appears on the screen: Name of the workgroup System date Changing the In Easy mode, the symbol is continuously shown at the bottom of the screen. If user mode you do not see this symbol, the Commander is in Professional mode. To switch to Easy mode, open the system settings menu.
Working in Easy mode 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 2 In the next menu, select the Change group button. button. Result: A list with all the registered logger groups opens.
Working in Easy mode 5.2 Programming the loggers Introduction 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). Procedure To program the workgroup proceed as follows: Step 1 Description In the main menu, select the Prepare loggers button. Result: The workgroup is shown.
Working in Easy mode Step 4 Description 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.
Working in Easy mode 5.3 Installing the loggers Basics 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.
Working in Easy mode Installation examples 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 36
Working in Easy mode 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.
Working in Easy mode 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.
Working in Easy mode 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.
Working in Easy mode 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.
