Users’ Manual ESDL-30 datalogger operation CARE OF BATTERY Data logger’s Battery The ESDL-30 SDI-12 Datalogger with internal battery uses two primary D-cell non-rechargeable batteries as a power source. If the ESDL-30 SDI-12 Datalogger is not going to be used for more than 30 days, remove the batteries from battery compartment. When battery voltage is showing 10 percent of battery capacity left in system information screen (at Readout unit), replace the battery at the first opportunity to avoid data loss.

Users’ Manual 1 1.1 ESDL-30 datalogger operation INTRODUCTION 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.
Users’ Manual 2 ESDL-30 datalogger operation 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.
Users’ Manual 3 ESDL-30 datalogger operation DATA LOGGER SETUP Refer following steps to setup data logger for first time. 3.1 Connecting Sensor Cable Refer following steps to connect SDI-12 sensor with data. 1 Open the data logger by unscrewing the 4 screws provided at top cover. 2 Unscrew the cable gland (CG-1) of data logger cable gland holder and pass sensor cable end through cable gland assembly as in Figure 3-3.
Users’ Manual ESDL-30 datalogger operation Figure 3-3: Connecting the sensor cable to sensor end connector 3.2 Inserting SIM Card A GPRS enabled SIM card is required for Dataloggers those are having telemetry option to upload logged data to remote FTP server. Refer following steps to insert SIM card into Datalogger. 1 Remove the top cover of data logger by un-screwing the four screws on the top cap of the data logger.
Users’ Manual 4 ESDL-30 datalogger operation POWER SUPPLY ESDL-30 SDI-12 Datalogger can be powered by either of 3 options. 4.1 Using 1.5 V Alkaline Batteries Using 3.6 V Lithium Batteries 12 V external powered. 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.
Users’ Manual 4.3 ESDL-30 datalogger operation 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 (+/-).
Users’ Manual 5 ESDL-30 datalogger operation DATALOGGER SDI-12 BUS POWER OPTIONS SDI-12 Bus can be powered by either of 3 options. 5.1 Using 12 V Internal Power Supply Using 12 V External Supply (with ON/OFF Control) Using 12 V External Supply (without ON/OFF Control) Using 12 V Internal Power Supply Option Datalogger with this option uses internal power supply to generate 12 V power supply to power the SDI12 Bus.
Users’ Manual 6 ESDL-30 datalogger operation COMMUNICATION INTERFACE Data logger can be configured by application software using communication cable. These methods are explained in following sections. 6.1 Communication Cables Communication cable has 4 pins USB connector at one end and 9 pins D-sub connector at another end. Connect 9 pins D-sub connector of the Interface Cable to the Data Logger and other end with USB socket at PC/Laptop.

Users’ Manual 8 8.1 ESDL-30 datalogger operation DATA LOGGER INTERFACE SOFTWARE ESDL-30 SDI-12 Datalogger Configuration Manager for PC/Laptop The application is configuration manager software for ESDL-30 SDI-12 Datalogger. 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.
Users’ Manual 9 ESDL-30 datalogger operation 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.
Users’ Manual ESDL-30 datalogger operation 10 OPERATION AND MAINTENANCE Although the ESDL-30 SDI-12 Datalogger automatic water level monitoring system is almost maintenance free system for long time monitoring, however it may require battery replacement. 10.1 Battery Replacement 1 Launch the configuration manager and connect the data logger. 2 Shut down the data logger from applications home screen and remove the USB to RS232 cable. 3 Hold data logger in the position as shown in Figure 10-1(left).
Users’ Manual ESDL-30 datalogger operation 11 TROUBLESHOOTING 11.1 Unable to connect to the Data logger RS232 interface connector may be loose. Check the RS232 interface cable’s connector for damage. RS232 interface cable may be broken. Data logger’s battery may be discharged.
