Users Manual ESDL-30 datalogger operation 1 INTRODUCTION 1.1 Overview The ESDL-30 SDI-12 Datalogger is designed to be very simple to use, be deployable in harsh environments and to be as compact as possible. The user-friendly software and standard D-cell batteries allow easy downloading of the data and maintenance in the field. Even users with very little experience with Geotechnical Instruments will be able to connect, download data and change settings with a matter of a few inputs. 1.2 System Components The automatic water level monitoring system model ESDL-30 SDI-12 Datalogger consists of the following system components and accessories:

Datalogger with internal battery back-up and communication option Configuration software CD USB to serial interface cable Installation accessories (Screw Driver) Data SIM (For telemetry option) Figure 2-1: Data logger and sensors connection diagram Page | 1 Users Manual ESDL-30 datalogger operation 2 OPERATING PRINCIPLE ESDL-30, SDI-12 Universal Datalogger is designed to record data produced by the sensors connected to SDI-12 bus. Datalogger is having 3 SDI-12 ports (channels). Sensors having SDI-12 interface can be connected on a common SDI-12 bus. This bus can be connected to any SDI-12 port of the Datalogger. Each reading is stamped with date and time at which the measurement was taken. It has non-volatile flash memory to store up to 2 million data points. These data files can be downloaded to PC using Configuration Manager by connecting logger with data cable. The downloaded readings get stored in the PCs Home Directory in CSV format. The downloaded files can be transferred to FTP server using internet connection. It can be processed on any common available spreadsheet like Microsoft-Excel. ESDL-30 with built in LTE has capability to upload data records directly to remote FTP server. Upload schedule can be set in Data logger using this software for automatic data upload to FTP server. Schedule can be set as fast as 5 minutes. Figure 2-1 shows the Datalogger and sensor connection diagram.

Using 1.5 V Alkaline Batteries Using 3.6 V Lithium Batteries 12 V external powered. 4.1 2 X 1.5 V Alkaline battery option Datalogger with this option uses 3 V powered power supply module. In this option, two D-size 1.5 V standard Alkaline Primary Batteries can be used to power-up the Datalogger. If user dont want to use D-

size batteries alternatively; user can use 3 V uninterrupted power supply (3 V/2 A battery backed PS). For this option, connect 3 V external supply at Datalogger Power Terminals (+/-). Figure 4-1 Datalogger powered with 2 x 1.5 V Alkaline Batteries 4.2 2 X 3.6 V Li battery option Datalogger with this option uses 7.2 V powered power supply module. In this option, two D-size 3.6 V standard Lithium Primary Batteries can be used to power-up the Datalogger. If user dont want to use D-

size batteries alternatively; user can use 7.2 V uninterrupted power supply (7.2 V/1 A battery backed PS). For this option, connect 7.2 V external supply at Datalogger Power Terminals (+/-). Figure 4-2 Datalogger powered with 2 x 3.6 V Lithium Batteries Page | 5 Users Manual ESDL-30 datalogger operation 4.3 12V External Powered (Mains/Solar) Datalogger with this option uses 12 V powered power supply module. This 12 V supply can be fed through either of various options like. 12 V/ 1A from Mains Adaptor 12 V/1 A from solar panel 12 V/1 A from Battery backed power supply etc Following Figure (Figure 4-3) showing an example of external power supply option. Connect 12 V external supply at Datalogger Power Terminals (+/-). Figure 4-3 Datalogger powered with 12 V Solar powered Important Do not insert batteries into battery holder if Datalogger is powered with external power source. Page | 6 Users Manual ESDL-30 datalogger operation 5 DATALOGGER SDI-12 BUS POWER OPTIONS SDI-12 Bus can be powered by either of 3 options. Using 12 V Internal Power Supply Using 12 V External Supply (with ON/OFF Control) Using 12 V External Supply (without ON/OFF Control) 5.1 Using 12 V Internal Power Supply Option Datalogger with this option uses internal power supply to generate 12 V power supply to power the SDI-

12 Bus. This 12 V supply is generated either from 3 V in 3 V Datalogger PS option or from 7.2 V in 7.2 V Datalogger PS option or from 12 V in 12 V Datalogger PS option. SDI-12 Datalogger when idle keeps SDI-12 bus power disable to save the power. It enables 12 V Bus power when required either for scanning or for other queries. There is no need of any 12 V external PS to power the bus with this option. This 12 V Bus power option has limited current capacity. It can power the SDI-12 Bus up to 70 mA current at any channel (CH-1, 2 or 3). SDI-12 Bus with Internal 12 Power supply option is suitable for low power SDI-12 sensors or few sensors connected to SDI-12 Bus. If Bus current is exceeding 70 mA then user can opt for 12 V external to power up the Bus. 12V external Bus power is recommended if large numbers of sensors are connected to SDI-12 Bus or when Datalogger is scanning at fast scan intervals because it will affect battery backup. 5.2 Using 12 V External Supply (with ON/OFF Control) option Datalogger with this option uses 12 V external power supply to power the SDI-12 Bus. Connect 12 V external supply at Bus Power Terminals (+/-). This 12V Bus power option can power the SDI-12 Bus up to 3 A current at any channel (CH-1, 2 or 3). SDI-12 Datalogger when idle keeps SDI-12 bus power disable to save the power. It enables 12 V Bus power when required either for scanning or for other queries. 12V External Supply BUS Power SDI-12 BUS CH-1/2/3 SIG GND

+12V SDI-12 Datalogger 5.3 Using 12 V External Supply (without ON/OFF Control) option To SDI-12 Sensors Datalogger with this option uses 1 2V external power supply to power the SDI-12 Bus. Connect 12 V external supply at SDI-12 Bus. Keep the Bus Power Terminals (+/-) at Datalogger open. The entire SDI-

12 Bus will always be powered ON with this option. SDI-12 Datalogger will not control the 12 V Bus power. This option is suitable for SDI-12 sensors application where SDI-12 sensor to be kept ON always SDI-12 BUS CH-1/2/3 SIG GND BUS Power SDI-12 Datalogger 12V External Supply

The data logger can be configured through this software. It analyzes the data files produced by the ESDL-30 SDI-12 Datalogger. The application displays raw data and parameter as per set monitor interval. By setting the log interval for scanning, the readings can be scanned which gets saved in the loggers non-volatile memory. After download, the application allows the user to analyze the readings obtained from the data logger in tabular and graphical form. The software is designed in a very user friendly manner which can be operated very easily for downloading of the data and analyzing the readings. Even users with little experience with Geotechnical Instruments can connect, download data and change settings as and when required. Figure 8-1 ESDL-30UNI Configuration Manager Application running on PC Page | 12 Users Manual ESDL-30 datalogger operation 9 WEB BASED DATA MONITORING SERVICE (WDMS) The data on variation of water level collected from a large number of boreholes need to be presented as time Vs water level graphs or as tables for visualization or further analysis. Also the data may be required by a number of people sitting at different geographical locations simultaneously. Web Data Monitoring software provided by Encardio-rite aids in the above process. It looks at the collected data and makes them immediately available in the form of time vs level plots or in tabular form. The user will have to maintain a desktop PC with an internet connection with static IP and running windows operating system and Microsoft IIS (Internet Information Service) server to run this software. Authorized users from anywhere in the world can then login the website using the supplied user name and password and access the graphs and tables using any internet connected computer and a standard web browser like Microsoft Explorer, Google Chrome, Firefox etc. Figure 9-1 showing an example of Borehole data presented in graphical form. Figure 9-1: Data display on remote PC In case a user does not want to host his own server, Encardio-rite can provide this as a service at a low cost. This service is known as Web based Data Monitoring Service (WDMS) and is available to users throughout the world.
