.
- The storage location 0 N calculates the average values for open-circuit voltage and short-
circuit current from all stored measured values.
8.7.6 Reading out the measured value memory via the USB interface
To read out the measured values via the USB interface
7
, you have to install the hardware driver
from the "Treiber-driver" directory on the enclosed CD-ROM and then the download program
from the CD-ROM's "Programm-program" directory on your PC once.
In order to download the data, please proceed as follows:
- Disconnect all safety measuring leads from the BENNING PV 1-1.
- Connect the BENNING PV 1-1 to your PC by means of the USB connecting cable.
- The hardware driver is installed automatically on a free COM port and confirms that the new
hardware can be used.
- The COM port used can be viewed by means of the Device Manager of your system.
- Start the "BENNING SOLAR Datalogger“ program, in the “Tools” menu click “Refresh Ports”
and select the corresponding COM port. Then, click “Download”.
- Press the -key
6
at the BENNING PV 1-1 for approx. 2 seconds until the download is
made and the complete measured value memory will be read out.
- The measured values can be stored as (*.csv) or (*.txt) file.
- Click “Open” to open the measured series e. g. via a spreadsheet.
8.8 Radio connection to BENNING SUN 2 – wireless SUN link
The BENNING PV 1-1 is able to receive the measured values (insolation, PV module / ambient
temperature and date / time stamp) of the insolation and temperature measuring instrument
BENNING SUN 2 (optional) via radio connection.
For this purpose, the BENNING PV 1-1 has to be coupled with the BENNING SUN 2 once.
Typical radio range of the BENNING SUN 2 in open space: approx. 30 m
Buildings / metal structures or interfering signals can reduce the radio range.
8.8.1 Coupling with insolation / temperature measuring instrument BENNING SUN 2
- Remove all electronic devices in direct vicinity.
- Switch the BENNING PV 1-1 and the BENNING SUN 2 off.
- Press and hold the two ON/OFF keys of the BENNING SUN 2.
- Press and hold simultaneously the
R
PE
-key and the
Auto
-key of the BENNING PV 1-1.
- The BENNING PV 1-1 indicates the successful coupling by means of an acoustic signal and
by displaying the serial no. of the BENNING SUN 2.
- The "W/m
2
" symbol is shown on the LC display of the BENNING PV 1-1.
8.8.2 Decoupling from the insolation / temperature measuring instrument BENNING SUN 2
- Remove all electronic devices in direct vicinity.
- Switch the BENNING PV 1-1 off.
- Press and hold the
R
PE
-key and the
Auto
-key of the BENNING PV 1-1 for approx. 10 seconds.
- The BENNING PV 1-1 indicates the decoupling from the BENNING SUN 2 by means of an
acoustic signal and by clearing the LC display.
- The "R
PE
/Ω" symbol is shown on the LC display of the BENNING PV 1-1.
8.8.3 Activating / deactivating the radio transmission of the BENNING SUN 2
- Couple the BENNING PV 1-1 with the BENNING SUN 2.
- To activate / deactivate the radio transmission, press and hold the -key of the BENNING
SUN 2 and simultaneously press the -key. A flashing triangle above the -key shows
that the radio transmission has been activated.
- If the BENNING PV 1-1 is within the radio range of the BENNING SUN 2, the measured
insolation value (W/m²) is shown on the LC display of the BENNING PV 1-1.
- Besides the electric variables (Vo/c, Is/c, R
ISO
), an AUTO measurement by means of the
BENNING PV 1-1 additionally measures the insolation, the module and ambient tempera-
ture as well as the date / time stamp of the BENNING SUN 2.
- If the BENNING PV 1-1 is outside the radio range of the BENNING SUN 2, the "W/m²" sym-
bol on the LC display starts flashing. Moreover, "_ _ _ _" is shown on the LC display, if the
measured insolation value is outside the measuring range.
See gure 9: Radio connection to the optional insolation and temperature measuring
instrument BENNING SUN 2
Note:
If the BENNING PV 1-1 does not receive any radio signal from the BENNING SUN 2, the display
indications are stored with the date / time stamp of the BENNING PV 1-1.
9. Maintenance
c
Before opening the BENNING PV 1-1, make quite sure that it is voltage free!
Electrical danger!
Work on the opened BENNING PV 1-1 under voltage may be carried out only by skilled
