Quick configuration with the software Avelour We will show here the classical version of the system programing, level measurement and data sending by 2G, 3G, LTE or NB-IoT. a. Necessary equipment

- The Avelour software

- Programing Wiji kit or Wiji key Avelour Wiji kit Wiji key a. Prerequisite

- The material is considered to be directly functional

- All indications contained in this document correspond to programming with Avelour IJINUS 25 ZA de Kervidanou 3 29300 MELLAC FRANCE - www.ijinus.com - sales@ijinus.com 6 Installation Guide K0J00025-EN-A03 b. First step : Run Avelour and connect to the sensor to configure After connection of the Wiji kit (or the Wiji key) on your computer USB port, run the Avelour software. Click on the button Connect to a wireless device then the logger will be directly visible by its part number (SN) without the need to activate anything else (ex: IJA0101-0000 3559). Locate the sensor's serial number (SN) on the sensor label and click "OK". On the first connection with the sensor only the serial number will appear. The following connections you will see also the name of the installation site or another name that you define. c. Second step : Selection of the sensor to configure, eventually a firmware update would be suggested During its connection with the sensor, the following pop up appears:

When connected, and only if the sensor already has measurements in memory, the following options will suggest you to retrieve the measures:

After your choice of these options, if the sensor is not up to date (case of new firmware developed since your last connection or you are now connected with a new version of the software Avelour). It is strongly recommended to read carefully the different messages in the options windows. The firmware update can last a moment, so it is advised to do it while in your office. On-site prefer the best radio connection (so not if the metal cover of a manhole is closed). IJINUS 25 ZA de Kervidanou 3 29300 MELLAC FRANCE - www.ijinus.com - sales@ijinus.com 7 When the sensors is ready, Avelour will look like bellow:

Installation Guide K0J00025-EN-A03 d. Third step : Configuration of Measurement part This part is divided in several paragraphs. Each part will be detailed. General informations This part is useful to describe the measurement point. The most important information would be the name that will help you to find your sensor at a future connection. Measures Choice of the application to configure This part is the most important, it allows you to configure your sensor. First, click on the button Add, then choose Water height for example. IJINUS 25 ZA de Kervidanou 3 29300 MELLAC FRANCE - www.ijinus.com - sales@ijinus.com 8 Installation Guide K0J00025-EN-A03 Choice of the measurement period In this new menu, select the measurement frequency (in this example every 15min). To the right of the measure period selector, 2 little icons allowing a deferred programming according to the time period and day of the week you can choose from. So far the sensor is not calibrated. Calibration of the water height After clicking the calibration button the bellow windows appears:

IJINUS 25 ZA de Kervidanou 3 29300 MELLAC FRANCE - www.ijinus.com - sales@ijinus.com 9 Installation Guide K0J00025-EN-A03 It is difficult to establish rules but globally 3 cases may arise:

CASE 1 : Ideal case: unique echo (test in lab or if the sensor front flat water surface for example) A simple calibration would be possible. CASE 2 : Case of a classic manhole with an invert channel in the bottom. The figure bellow shows two echoes (the invert and the water). A calibration in advanced mode will be possible. First, check that the sensor is well positioned, fronting and perpendicular to the water. IJINUS 25 ZA de Kervidanou 3 29300 MELLAC FRANCE - www.ijinus.com - sales@ijinus.com 10 Installation Guide K0J00025-EN-A03 CASE 3 : Complex case The presence of many echoes make difficult the calibration the easiest way. A priority should be to move the sensor if possible otherwise go to the expert mode. (Only for experienced users). Calibration of the sensor Case N1 (Ideal) The first case presenting only one echo, you only need to adjust the water height H or the maximal distance between the sensor and the bottom Z and relaunch a measure. Note that it is possible to define a different zero point (zero at the level of an overflow threshold for example), very useful for CSO (Combined Sewer Overflow). Zero of the sensor (example of ideal case) On the right a different zero point Once done, the calibration has to be validated by clicking on Apply button. The configuration is then automatically saved in a file called configuration that is visible with the software even when not connected to the sensor. Please note that the figure presenting the echo as a power indicator, showing by a yellow dot line

(oblique from left to right). This one is very useful to fine tune the sensor. The echo should ideally be upward that line. A weak echo means measurement not precise, a too high echo provides accurate measures but use faster the energy. A temperature checking during the measure has also to be done (23C in this example). While the measure is temperature compensated, you should not calibrate a sensor when the temperature is too high and then asking it to measure on a different environment (typical case of 15C under a sewer manhole). IJINUS 25 ZA de Kervidanou 3 29300 MELLAC FRANCE - www.ijinus.com - sales@ijinus.com 11 Installation Guide K0J00025-EN-A03 Calibration of the sensor Case N2 (Classic example of a manhole with an invert channel) In case no. 2, with an echo having several peaks, the software indicates the presence of "critical" obstacles that can disturb the measurement if no modification is done to the calibration. These critical obstacles appear in red on the graph, while the echo reported by the sensor as the measurement is shown in green. The power indicator (yellow line) is always present. In this case, follow the following procedure:

- Activate the advance mode by clicking on the button at the top, The software displays a first step of calibration that is more precise and named Measures parameters: This parameter allows to extend the exclusion area corresponding roughly to the dead band of the sensor. This parameter is to be modified, mainly in the case of probes 0-6m if there are interfering echoes in this zone, or in the case of a probe mounted on an angular return bracket. The manipulation consists in increasing the value of the pink zone so it covers the different peaks for distances close to the probe, IJINUS 25 ZA de Kervidanou 3 29300 MELLAC FRANCE - www.ijinus.com - sales@ijinus.com 12 Installation Guide K0J00025-EN-A03

- This advanced mode also allows to create an obstacle filter that consist in masking obstacles echoes that disturb the measure like in the case of invert, ladder rungs present in the field of view of the sensor. After clicking on Create an obstacle filter, you need to choose with the tick box the obstacle matching the wanted measure (water height), press Create.

- Once the filter has been made and checked, you need to validate it by clicking the button Launch a new measure, then adjust either the H or the H2 to ensure the quality of water height measurements. Finally, this advanced mode allows to two other optimization operations and another filtered particularly efficient. One computation parameter often named oblique filter works as follow:

- Choose a Filter y-axis of 160 for example

- Adjust the filter slope until it becomes parallel to the power indicator (yellow line) and ends to the zero of the sensor.

- If you cant see that oblique filter, adjust the y-axis. The integrations count option, available for minimum, average and maximum, is the successive ultrasonic shoots treatment (3 by default). The average option does an average of those shoots. Most of the time the maximum option is to be chosen to get reliable measurements (and especially in presence of condensation) but also depends of the power setting of the sensor. IJINUS 25 ZA de Kervidanou 3 29300 MELLAC FRANCE - www.ijinus.com - sales@ijinus.com 13 Installation Guide K0J00025-EN-A03 Finally, you need to launch a new measure to check the relevance of the result so:

- The green line position used for the measure,

- Values of the echo slightly higher than the power indicator,

- and validate by pressing the Apply button Calibration of the sensor Case N3 (complex) Expert mode The expert mode is to be used only in complex cases and need user experience and knowledge of ultrasonic measure data processing. Various parameters and options are then available but wont be in this document. You need a password to go on expert mode. Please contact your sales representative or the after-sale services, the password as well as some information will be given. Temperature recording You can log the temperature thank to the internal temperature probe used to compensate the level measurement with ultrasonic. For information, the sound speed in the air at 10C is 337,6m/s. IJINUS 25 ZA de Kervidanou 3 29300 MELLAC FRANCE - www.ijinus.com - sales@ijinus.com 14 Installation Guide K0J00025-EN-A03 Change measure period on height threshold For some sensors, you can have two different time of data acquisition depending on water height measures. For example, you can measure every hour when the level is low and accelerate to 2 minutes when level goes above a threshold. This measurement period acceleration can be set to some time slots, following an exceedance of level (with or without hysteresis) and with the choice of a minimum time before deceleration. The limit of this acceleration is that it can only be done with a water height measurement. If you wish to accelerate the measures as soon as the water go over one level between two measurements, you have to connect one of our overflow detectors to the ultrasonic level sensor. Define a threshold / software overflow detection (Two can be set) After the programing of the first threshold, you can then define a second one. To go further and use the advanced parameters: Zoom on the debugging echoes (acoustic signature) and the replacement values in case of loss of echoes. All advanced parameters wont be explain here, but two zooms on very useful functionalities:

Debugging echoes The record of debugging echoes is very useful to log, when there is a difference between two successive measures (on rise and or on lowering: here 75mm for both), the acoustic signature of the measures named ultrasonic echo. A post review allows you to evaluate the quality of level measurements and to correct them if needed. For your first or complex installations, we strongly advice to activate this functionality. IJINUS 25 ZA de Kervidanou 3 29300 MELLAC FRANCE - www.ijinus.com - sales@ijinus.com 15

Installation Guide K0J00025-EN-A03 Height value for loss of echo In the field of ultrasonic, a loss of echoes is reflected by the absence of peaks (or a very weak peaks not detected as an obstacle) on echoes that materialize by a maximal height, the Z value defined during the calibration. This function is used when the sensor encounters this situation, to replace this value a priori false by another one defined by the user:

The last valid value, a value you define, no value, This option has to be appropriately used, it never should compensate a not completed or not adapted calibration. Programing for flow rate calculation from height measures and control a water sampler Before completing this chapter, it is important to keep in mind that a flow rate measure is obtained by two factors:

1) the wet area and 2) the average velocity. The sensors described in this document only measure water height (that allows wet area calculation via the collector shape) but never a velocity measure. Nerveless some tools to transform water height measured in flow rate (then in volume) by conversion table or measuring system on threshold are available. It is the users responsibility to choose the transforming tool. In this case, it has to be chosen at the beginning of the programing (or to modified) height/flow rate like shown below. Once the programing choice has been done, an example sheet of conversion is available:

An Excel file will then open with in summary the different type of use. For example, in case of circular collector, the sheet called Height/surface - circle allows you to generate a value table (mm) / Area (mm) for a circular collector (here for 1500 mm) with the possibility to integrate mud height, this for a scale every 5 mm. Only the yellow cells have to be filled, conversion is done automatically. IJINUS 25 ZA de Kervidanou 3 29300 MELLAC FRANCE - www.ijinus.com - sales@ijinus.com 16 You need to select, copy the bloc Height/Area in Excel (bellow example) and paste the data from clipboard. Final validation is done by pressing the OK button Installation Guide K0J00025-EN-A03 This operation validates the input of these data in the table by displaying the number of lines, then can activate, depending on calculation needs, flow logs and eventually to control a water sampler. Once the programming is done, a resume summarized your different choices Finishing of the programming: you have to validate with the Program the device button to send the configuration in the sensor memory:

After the saving operation is done please check that you have at the top right corner the two green sign showing that the sensor working and recording, and also sending data. You can stop them both by pressing the red Stop icon, if needed. IJINUS 25 ZA de Kervidanou 3 29300 MELLAC FRANCE - www.ijinus.com - sales@ijinus.com 17 Installation Guide K0J00025-EN-A03 e. Fourth step : Data reading in real time You Have two possibilities to read the data in real time: By pressing the Test measure button, or by selecting on the main menu the window View broadcast measures (Main menu > Windows > View broadcast measures) View broadcast measures: this option opens a window showing the measures received by radio from Ijinus sensors and loggers nearby. Now you can also press the Test measure button for a direct reading f. Fifth Step : Retrieve and see locally your data by radio When connected to a sensor, the software directly asks you if you want to retrieve data. After you can find this command from the main menu: Menu > Actions > Retrieve measures IJINUS 25 ZA de Kervidanou 3 29300 MELLAC FRANCE - www.ijinus.com - sales@ijinus.com 18 You can view the data, even offline, on graphic and list. A graph configuration module allows you to changes colors, thickness of lines, , but also to apply statistical filters and formula to your data. Installation Guide K0J00025-EN-A03 g. Sixth step: Data export From The graph and/or list of data you find the tab Export the measures with the choice of different files format and style of reports, from date to date, by month, or simply all data. h. Seventh step: Pair devices Our level sensor can retrieve locally the data from other sensors and logger nearby by radio, and send them with its modem. To do this you need to check in Avelour what devices can be seen by the logger around it. In the Pair devices part, click the Edit button Then you need to click the Refresh button to run the test. Simply tick the boxes corresponding to the devices you want to associate. IJINUS 25 ZA de Kervidanou 3 29300 MELLAC FRANCE - www.ijinus.com - sales@ijinus.com 19 Installation Guide K0J00025-EN-A03 Check the strength of the radio signal by placing the cursor on the indicator (Be careful the quality of radio signal cannot be compared with cellular values: -70 dB is a bad quality for radio and excellent for cellular communication i. Eighth step : Data sending As we said at the beginning of the document different ways to send data are possible like SMS or FTP transfer. In this part I will show you the way to do it by FTP. First keep in mind that on the installation location if you already cant find operator signal in surface, it will be even more difficult while under a metal cover in the manhole. IJINUS 25 ZA de Kervidanou 3 29300 MELLAC FRANCE - www.ijinus.com - sales@ijinus.com 20 Installation Guide K0J00025-EN-A03 First of all you need to:

- Insert in the sensor sim holder a regular size data SIM card with at least 5 Mo per month available. While buying the card please ask the APN of the operator, as well as the PIN code if any. We will need these informations. The cellular antenna has also to be connected to the connector on top of the sensor.

- Set now your timezone in the System options menu:

- After clicking the Edit button, choose the sending period, define to send every day or only some of them. You can define several periods by clicking on the green + icon. Depending on your configuration you may need to choose a minimum delay between 2 anticipated data sending.

- If the sim card is locked, please enter your code (if any) and press the Inactive button (that will turn green, and become Active) and Program the pin code button.

- Enter your APN code and press the Program APN button. A message will confirm the success for each operations. By default, the parameters are set to send the data to our server as we propose a web platform www.ijitrack.com with different services to manage them. So if you choose this option, you dont have to change the FTP Username. At this step you can run a sending test by pressing the Force data retrieval button and check on www.ijitrack.com, in your account, if the sensors data appears. Of course if your account is already created. Please ask otherwise our customer service to do so for you. You should also write the Rfid product number on the label of the sensor, the address of the installation, you will need them later to set up the sensor on our web platform. IJINUS 25 ZA de Kervidanou 3 29300 MELLAC FRANCE - www.ijinus.com - sales@ijinus.com 21 The modem diagnostic button available on the modem configuration allows a better diagnostic of the 2G, 3G, LTE or NB-IoT reception by doing multiple measurements. Installation Guide K0J00025-EN-A03 If you use the advanced mode, you also do continuous modem measurements on a longer period. These options are practical to know on what side of the manhole to place the antenna before drilling in the concrete under the cover plate and inserting it. IJINUS 25 ZA de Kervidanou 3 29300 MELLAC FRANCE - www.ijinus.com - sales@ijinus.com 22 Installation Guide K0J00025-EN-A03 Advanced parameters If you need to send the data to your server, first click the View advanced parameters, then the FTP / internet Options will appear as well PPP options in the modem options. You need to fill in your own information details regarding your server access. Your server administrator can provide to you those information. After completing this chapter please press the Program the devise button, the configuration will be sent by radio to the sensor.

Elements for good practice and installation examples We propose here, and without being exhaustive, some elements of good practice such as:

- The sensor have to front and be perpendicular to the surface water to be measured. This surface has to be stable and without ripples for more accuracy, without foam). If possible, it shouldnt be any obstacle between the sensor and the water surface (if you cant avoid it, please refer to the calibration chapter to mask it with a filter).

- The calibration is compulsory and the verification of the max distance (Z) very important. Calibration has to be checked at least once a year.

- Sensors with ultrasonic technology dont need much maintenance, but at least once every six months you should clean it, check on-site the presence of debris, floating debris, anything hang to the sensor Finally, below are some photos of sensors installed in different environments:

Procedure for inserting the SIM card Installation Guide K0J00025-EN-A03 Loggers with 2G/3G or 2G/LTE/NB-IoT modem need a SIM CARD to send data. The card holder is located on the board. Following steps need to be respected to ensure proper operation of the device :

- The sensor must be in standby mode (no connection with our software Avelour or USB) for the modem to recognize the SIM card.

- Unscrew the ring then take off the cover.

- It is imperative not to leave the sensor open too long (max 2 min) the desiccant bags may absorb too much moisture and do not fulfill their role thereafter (condensation)

- Insert the SIM card (beveled edge side up right).

- Place the lid back (mind the notch) on the threads and screw back the ring to the end. IJINUS 25 ZA de Kervidanou 3 29300 MELLAC FRANCE - www.ijinus.com - sales@ijinus.com 27 Installation Guide K0J00025-EN-A03 77. Procedure for removing a battery

- Unscrew the cover

- Remove the battery from its housing and disconnect.

- Throw away the desiccant bags present in the sensor if they are green
