El data logger EOL Zenith recopila datos de acuerdo con la norma IEC 61400-12 para realizar una evaluación de alta calidad de los recursos eólicos y solares, en casos en los que se requiere el máximo rendimiento, fiabilidad y facilidad de uso.

El EOL Zenith está diseñado para un rendimiento óptimo en cualquier clima, desde los fríos del norte de Noruega hasta el calor del desierto de Egipto.

Este rendimiento excepcionalmente versátil se debe a la electrónica cuidadosamente diseñada, a los componentes robustos y fiables, y al bajo consumo de energía del data logger, característica que sigue siendo única en el EOL Zenith y de crucial importancia cuando se opera en áreas remotas. Entre las características específicas del diseño se incluyen:

Frecuencia de muestreo de 1 Hz (conforme a IEC 61400-12)
Diagnóstico avanzado de errores del sensor
Datos en tiempo real (comunicación bidireccional)
Sello de tiempo GPS y sincronización
Descarga automática de archivos
Múltiples opciones de entrega y reenvío de datos
Intervalo de promedio de 10 minutos (a elección del usuario)
Cifrado de datos y protección con contraseña de 2 niveles
No se requieren tarjetas de interfaz
No se requiere programación
Capacidad de SCADA/Modbus (opcional)
Capacidad de conectar sensores ultrasónicos (opcional)
Herramienta de gestión de torres de medición (EOL Manager) que ayuda a realizar un seguimiento de todos sus sitios

El data logger EOL Zenith ofrece una amplia gama de posibilidades, siendo el componente central de las campañas de medición del recurso eólico. Por defecto, el data logger viene equipado con capacidades de comunicación GSM/GPRS. Debido a su bajo consumo de energía, un panel solar de 10 W es suficiente para su funcionamiento estándar (dependiendo de las horas de sol, latitud, etc.)

The software and remote monitoring system for the EOL Zenith data logger ensures reliable and easy access to wind data and logger status, and forms an integral part of the data acquisition system.

Download data, collect real-time values, refine logger settings remotely and keep all your wind data organized.

Dashboard with site-by-site status, with direct access to site coordinates via Google Earth
Automatic data download from unlimited number of sites
Advanced sensor error diagnosis
User selectable output format incl. EPE (Brazil) and MGM (Turkey)
Upload new logger settings OTA
Live real-time data (bi-directional communication)
Multiple data delivery and forward options
User configurable password protection

EOL Manager includes advanced graphics for more accurate wind data trouble-shooting as well as enhanced control of multiple wind assessment sites with automatic and real time connectivity.

In short EOL Manager offers ‘at a glance’ status of all your data loggers in the field with easy identification of sensor faults. It also allows for configuration of the data loggers, download frequency etc.

What format should the SD memory have for it to work with the EOL Zenith?

If you are using the SD memory card that was supplied together with the data logger, the SD card is already formatted.

In case you want to re-format a SD card please follow these steps:

Turn off the data logger
Insert the SD card you want to format into the data logger
Turn the data logger on
Wait for at least 12 minutes

The SD card is now formatted correctly.

Can I use any SD memory card with the data logger?

Yes, you can use any SD memory card (with a maximum capacity of 2GB). However, not all SD memory cards have the same quality. We strongly recommend using the industrial grade SD memory card that is supplied together with the data logger.

Please make sure that the SD card is correctly formatted before use.

How does the data management system work for the EOL Zenith?

The EOL Manager is used to prepare the configuration file for the EOL Zenith data logger. The .sit file (configuration file) is then uploaded to the data logger.

EOL Manager downloads the encrypted .log file from the data logger. The .log file contains all the RAW data (the pulses and Hz stored from all the sensors connected to the data logger)

EOL Manager then automatically converts the .log file into a .wnd file and .txt file using the active logger configuration file (also stored on your PC)

There is no GSM coverage on the site where I plan to install my next wind measurement mast. What should I do?

We offer two alternative satellite solutions, Iridium and BGAN. Either solution enables you to connect with data loggers installed in remote locations without GSM coverage while maintaining full compatibility with the other features and accessories of our data loggers, including:

Live data connections
Remote modifications to logger settings incl. firmware upgrades
Automatic data download
GPS coordinates
Windfarm Monitoring Module

What battery should I use for the data logger?

We recommend using a flotation (back-up) sealed lead-acid battery (12VDC). This kind of battery has no maintenance and can be transported in any orientation. If you are performing wind measurement and are using an internet / GSM connection to your data logger, we recommend using a 24Ah battery. This gives autonomy of approximately 1 month without the battery being recharged.

How do I make sure my solar panel is charging the battery correctly?

To test that the solar power supply system has been installed and performs properly you need a multimeter set to “Read Current” mode.

Step 1

To begin with you should check if the output from the solar panel is correct. You should do this on a sunny day (Please connect the multimeter as shown in the drawing below).

Step 2

Now check that the regulator is charging the battery. There are lEDs on the solar regulator helping you to indicate if the regulator is charging the battery. But to be sure you should check with the multimeter (see drawing below)

Figure 1.1B

In addition to dimensioning the solar power supply system correctly, it is important to position the solar panels appropriately for maximum electricity production.

How should I install the solar panel for charging the battery?

In addition to dimensioning the solar power supply system correctly, it is important to orientate the solar panels appropriately for maximizing the energy production during the season with less sun energy.

In general the solar panel should be facing GEOGRAPHICAL SOUTH in the Northern hemisphere and GEOGRAPHICAL NORTH in the Southern hemisphere. And as a rule of thumb the inclination of the solar panel should be the latitude of the site where you are installing the solar panel -10°.

E.g. For an installation in Germany, close to Frankfurt (with latitude 50° N) you should orientate the solar panel towards SOUTH and with an inclination of 40° with respect to horizontal.

For sites in the North (e.g. Scandinavia), or where there may be very little sunlight during certain periods of the year, an individual solar radiation calculation should be carried out. You can contact our technical support for help on this.

Tropical and Equatorial sites

In inter-tropical latitudes the sun can be located either North or South. In the equator, for example, the met mast structure shadow is projected to the South for 6 months and to the North for the other 6 months. This of course lowers the radiation on the solar panel and we therefore recommend installing two separate solar panels.

Installing two solar panels

If you are going to install two separate solar panels, we recommend the following configuration (see images below). Both panels are to be installed in booms parallels to the West-East Earth axis, with one solar panel pointed towards the North (and tilted approx. 10°) and the other one pointed towards the South (and tilted approx. 10°). The charging efficiency is increased by using independent solar chargers for each solar panel.

How should I connect the power supply to the EOL Zenith data logger?

Usually solar power systems for the EOL Zenith consist of a solar panel, a charge controller and a battery.

Important!

Always connect the battery terminals directly to the BAT + and – on the data logger. Do not connect the LOAD+ and LOAD- to the data logger. The reason we recommend this is to avoid the regulator to switch off its outputs when the battery drops below a certain cutoff limit for the regulator. Keep in mind that the data logger can work with 5V. See drawing below.

How should I ground the data logger correctly?

To ground the EOL Zenith®, connect one end of the copper ground wire (usually yellow-green color) to the data logger GND terminal and the other end to an independent grounding spike.

If the enclosure is metallic you must also connect the enclosure to the ground wire, to do so, all metallic enclosures have a connection screw terminal with the ground symbol on it.
