1 INTRODUCTION 1.1 System Overview LeNETmobile is essentially a GPRS enabled multi-channel data acquisition device for remote live monitoring solutions. It continuously collects information from the connected sensors and automatically sends data updates to LeSENSE web server, regularly via the GSM/GPRS network. Some key features of LeNETmobile are: • 8 x Digital Input ports • 6 x Analogue Input ports • Wireless: GSM/GPRS technology for remote data updates • LeSENSE web portal: for data access, management, analysis and manipulation • Flexible powering options: Batteries, Solar panel, or Mains power supply Figure-1 LeNETmobile & LeSENSE typical Applications

1.2 Input Ports and Sensor Compatibility LeNETmobile has capability to monitor 8 digital and 6 analogue sensors with its input ports that are grouped as digital ports (A1-A4, D1-D4) and analog ports (D5-D10) and are compatible with a variety of sensors. - See Appendix-A for details about specification of the sensors compatible with LeNETmobile - The following table shows LeNETmobile ports with different configuration modes and sensor compatibility: Input Ports Configuration Mode Sensors Compatibility A1 - A4 Low AC waveform Low AC sensors (such as NRG, C3 anemometers ) Digital A1 - A4 D1 - D4 Dry contact pulse Standard pulse output sensors Opto-isolated pulse and dry-contact switch pulse sensors (electricity kWh meters, Heat Meters, Flow meters, Gas meters, reed-switch sensors, Rain collectors, etc) 24 VDC pulse 24 VDC mode for industrial applications Analog u D5 - D10 0 - 3.3 VDC Analogue sensors with DC output voltage or current loop (wind vanes, temperature, humidity, solar radiation, pressure sensors) 0 – 5 VDC 0 - 20 mA Note: see section 2.2 “input ports setup” on how to setup for different configuration modes. 1.3 Data Management LeNETmobile can operate on two modes: Meteorolical or Energy metering applications. Data is sampled every second for Meteorological and Wind Applications. For Energy applications a discrete count system is used. Data is grouped every 10 minutes in averages, totals or other statistical values depending on application. Table 1.3 shows the raw data type for LeNETmobile ports. Notice that some ports (A1-A4, D1-D6) have more than one form for raw data, which is preset at the factory depending on the application. Input Ports A1 - A4 AVG, MAX, STD (Hz) Accumulative Pulse Counts D1 - D4 Periodic Pulse Counts & Accumulative Pulse Counts D5 - D10 Average Analogue Value D11 Battery Voltage

At every recording interval (measurement period of 10 minutes), calculated data is updated on: 1- LeSENSE web portal, where data is stored on secure and reliable SAS70 Type-11 certified data centre technology system. Data can be accessed, managed, analyzed and manipulated in a variety of useful ways. (refer to section-3 for more details, for complete details refer to LeSENSE manual) 2- Micro SD card, where data is logged onto a log file in CSV format for local backup

The table below shows a general guide to the jumper configuration for various sensor/signal types. The jumper settings are shown with the LeNETmobile in the same orientation as the other diagrams in this manual. Input Ports Configuration Jumpers Setting Configuration Mode Sensors Compatibility Digital A1 - A4 Low AC waveform low ac output sensors (such as NRG, C3 anemometers ) standard pulse output sensors including optical pulse and dry-contact switch pulse sensors (such as Energy meters/KWH meters, Heat Meters, Flow meters, Gas meters, reed-switch anemometers, Rain collectors, optical sensors) 24 VDC mode for variety of digital pulse signals (24VDC signals) Standard Pulse 24 VDC pulse D1 - D4 Standard Pulse 24 VDC pulse Analogue D5 - D10 0 - 3.3 VDC Analogue sensors with DC output voltage or current (such as potentiometer type wind vanes, temperature, humidity, solar radiation, pressure sensors) 0 – 5 VDC 0 - 20 mA Note: A digital port that is not used should be configured as dry contact and any analogue port that is not used should be set to 0 – 5 VDC modes. The following points should be considered before connecting the sensors with the LeNETmobile: Some general instructions about the sensor installation are given below: • LeNETmobile should be powered OFF before connecting or disconnecting sensors. • For the sensors employing shielding wire, make sure that shield is connected to ground (GND) port at LeNETmobile and is not connected at the sensor side.

SETUP Installation Manual Page 10 © Logic Energy Ltd. Registered in Scotland • Connect GND and Shield cable first, and disconnect them last. 2.3 GSM/GPRS Configuration Note: For SIMs not supplied by Logic Energy Ltd, GPRS config parameters must be set up before use. To configure the LeNETmobile for your own SIM, you need the GPRS APN, username and password from your network provider, plus the radio band that you provider uses (e.g. GSM900). Moreover you also need SD card reader (this is built into some PCs) and a micro-SD adapter in order to read micro-SD card. 1. Ensure the LeNETmobile is switched off. Unscrew and remove the end cover from the LeNETmobile enclosure. Remove the micro-SD card from the LeNETmobile by gently pushing it in to unlatch it. 2. Insert the micro-SD card into your card reader, and browse to the config_backup folder on the card. Open the config.txt file in a text editor such as Notepad. 3. The file config.txt specifies the GPRS config parameters to use for the GSM network connection. An example config.txt file might look like this: [GPRS] apn=yourapn.com usr=username pwd=password bnd=0 4. Change the APN parameters to match those from your provider. For example: [GPRS] apn=internet usr=web pwd=web bnd=0 5. Set the bnd parameter, as shown in the table below bnd=0 GSM900 and GSM1800/DCS1800 (Most countries outside the US/Canada) bnd=1 GSM900 and GSM1900/PSC1900 bnd=2 GSM850 and GSM1800/DCS1800 bnd=3 GSM850 and GSM1900/DCS1900 (USA/Canada and some of South America) 6. Save the file, and then copy (not move) the file to the root (top level) folder of the SD card. 7. Eject the card from the reader and insert it into the LeNETmobile by pushing it into the socket until it clicks and locks into place. Then switch ON the LeNETmobile.

SETUP Installation Manual Page 12 © Logic Energy Ltd. Registered in Scotland 2.4 Power Supply Setup Depending on the installation type, there are various ways to power the LeNETmobile. • For remote sites and long term monitoring, a PV kit (solar panel and battery) is recommended. • For cost-conscious installations, a replaceable industrial alkaline battery pack can be used. • For indoor or energy metering systems, a mains power supply is suitable. Note: The power supply positive wire connects to the LeNETmobile PWR+ terminal, and the negative wire connects to the GND terminal. 2.4.1 PV Kit Power Supply The LeNETmobile can be powered from a 6V or 12V rechargeable battery and PV panel kit for reliable long-term operation on remote sites. • The solar panel works best when it receives full sunlight, so mount it away from fences, buildings, trees or other obstructions that may cast shadows on it. • The panel should be mounted facing south in the Northern Hemisphere, and facing north in the Southern Hemisphere for maximum sun exposure. The vertical angle depends on latitude (usually about 30º angle) • Mount the enclosure and panel on the mast, mount pole or wall with appropriate brackets. • Connect the PV kit output cable to the LeNETmobile power terminals: “+” (red or white wire) to LeNETmobile “PWR +” and “–” (black wire) to LeNETmobile GND. 2.4.2 Mains Power Supply The LeNETmobile can be powered from any mains power supply that can provide up to 2 Amps at typically 9 Volts. This is typically a plug-pack or DIN-rail switching supply. Connect the supply output directly to the LeNETmobile power terminals, and avoid use of excessively long cables. 2.4.3 Battery Power Supply The LeNETmobile can be powered from an alkaline battery pack consisting of 6 D-cells. Only use good quality industrial cells for maximum life. These will typically last around 3 months. Always use LeSENSE to monitor the battery voltage, and/or set up a LeSENSE alert to warn of low battery. The alert trigger point should be set at 7.5V. See the LeSENSE user guide for details of how to configure alerts.

SETUP Installation Manual Page 13 © Logic Energy Ltd. Registered in Scotland 2.5 Installation Checklist Before powering up the LeNETmobile device, check that the installation is correct. Following is the quick checklist for installation: 1. Make sure the sensors connections are sound and the jumpers are configured correctly for each port connected to signal source/sensor. 2. For wind applications, the primary/top anemometer must be connected to port A1 and the primary/top wind vane must be connected to port D5. 3. An active GSM (Cellular) SIM is inserted in the GSM module. Also make sure the antenna is connected to the module. If using an external antenna, ensure it is securely mounted, and not obstructed by metal enclosures or masts and preferable vertical position. 4. If you are using your own SIM, then make sure that micro-SD card contains the correct GPRS settings in the configuration file. 5. Power up the device using appropriate powering source. Note: Once the system is in operation, check that the device communicates with the server, and that the server shows new data each measurement interval. Also check that data makes sense before leaving the installation site. 2.6 LEDs Status There are two LEDs on LeNETmobile to indicate its operating state. They are: • Activity LED (GREEN LED-gear wheel symbol) blinks every 1 second (or few seconds) during normal operation of the system, while the other LED stays OFF. This LED also indicates memory card access. • GSM LED (AMBER LED-antenna symbol) flashes during the communication cycle only, while the other LED stays OFF.

3 LESENSE MONITROING AND DATA ACCESS Once the LeNETmobile device is installed and powered ON, it automatically starts communicating with the LeSENSE web server for regular data updates. Note: It is recommended to check the LeNETmobile device’s status and data ports on the LeSENSE web portal after the hardware installation is complete and the device is in operation.

APPENDIX A SENSORS SPECIFICATION A-1 Energy Meter Specification The following are the main points when checking the compatibility of an energy meter with LeNETmobile. 1- The energy meter should have pulse output feature. 2- Any standard pulse output is compatible with LeNETmobile. 3- The pulse output rate varies depending on the amount of energy flow through the meter. For most scenarios, a pulse rate of 1000 imp/KWH gives advanced resolution.

APPENDIX B CONNECTION DIAGRAMS B-1 Energy Meters & Analogue sensors LeNETmobile is capable of monitoring upto 8 Energy meters (such as KWH meters, Heat meters, Flow meters) connected to ports A1-A4 and D1-D4. Moreover it can also monitor 6 analogue sensors connected to ports D5-D10.

B-2 Energy Meters & Solar Radiation Sensor This example shows the configuration jumper settings and sensors for a typical Solar PV metering installation, which monitors 2 energy meters (eg generation and export) and solar radiation. The energy meters (electrical or heat) must be configured to provide a pulse output (dry contact, KYZ or open-collector) of typically 1000 pulses per kWh depending on system size. Sensors: • Port D1 = Pulse output from generation energy meter (dry contact or open-collector) • Port D2 = Linked to port D1 • Port D3 = Pulse output from export energy meter (dry contact or open-collector) • Port D4 = Linked to port D3 • Port D7 = Solar Radiation sensor (Pyranometer) As the digital ports A1-A4 are not used, they are configured in dry contact mode. Similarly the analogue ports D8, D9 are not used, so they are configured as 0-5VDC mode.

B-3 NRG anemometers and wind vane This example shows the configuration jumper settings and sensor wiring for a typical wind monitoring installation using NRG #40C anemometers and NRG #200P wind vane. Note the jumper settings. Sensors: • Port A1 = Primary/top anemometer (NRG #40C) • Port A2 = Secondary/lower anemometer (NRG #40C) • Port D5 = Primary wind vane (NRG #200P) Shielded cables must be used for the anemometer and wind vane connections to ensure signal quality. Connect the shield to GND at the LeNETmobile. Do not connect the shield at the sensor. Additional anemometers can be connected to ports A3-4, and one additional wind vane can be connected to port D6. In LeSENSE wind reports, wind vane D6 will be associated with anemometer A2.

B-4 Pro-D anemometer and Temperature sensor This example shows a simple weather monitoring system, with an anemometer and wind vane combination instrument plus a temperature sensor. Other sensors such as rain gauges (tipping bucket), humidity, barometric pressure and solar radiation (pyranometer) can be added. Sensors: • Port A1 = Davis Pro anemometer (reed switch) • Port D5 = Davis Pro wind vane • Port D10 = NRG #110S temperature sensor (0-2.5V output) Note that the NRG #110S temperature sensor requires a power supply of minimum 4 volts, so it cannot be powered from the SPW terminal. It can easily be supplied from the same power source as the LeNETmobile as shown on the diagram below. The Davis Pro anemometer and wind vane is supplied with a pre-assembled cable. Simply cut off the connector and strip the cable end to reveal the cable colours shown on the diagram below. Wire these directly into the LeNETmobile terminals.
