5 Operation
The operation status is indicated by a LED inside the logger.
LED off (short flashes every 5 seconds)
The logger is in regular storage mode. The LED flashes every 5 seconds. In addition, it also
flashes according to the set sampling interval (every minute or every 10 minutes). This means
that data is recorded.
LED flashes rapidly
This means that the microSD card does not work or has not been inserted properly. It can also
mean that the logger is connected to a PC via RS-232 interface and is waiting for configuration.
Make sure that the microSD card is inserted properly and compatible with the logger.
Also check the power consumption of the card and the amount of data. A low battery voltage can
also cause this problem because the logger does not record data when the batteries are low.
LED on
The logger is connected to a PC via the RS-232 interface and the configuration is running. To set
up the logger via the RS-232 interface, you need to remove the microSD card.
5.1 Configuration
5.1.1 Configuration via SD card
Remove the SD card from the logger and use a card reader to connect it to your PC.
On the SD card, there is a “lewl_setup.exe” file. Run the file. The following window appears:
Once you have adjusted all settings to your needs, click on “Write setup file” to confirm the
settings. Insert the microSD card into the card slot of the logger. The settings are adopted
automatically and the logger is in recording mode.

5.1.2 Configuration via terminal program
The PCE-WL2 data logger has an integrated menu which can be accessed via the RS-232
interface. To configure the logger, you need a terminal program to be installed on your PC.
All parameters (except date and time) are saved to the device permanently and do not have to
be set every time. Make sure to set up time and date every time when using this configuration
method.
Note: If your operating system does not come with a terminal program (Windows 7 or higher), you
can download a freeware program from the internet. We recommend using “HTerm”.
Access the internal menu
Run the terminal program and adjust the interface settings as follows:
The COM port number that you are using
Data rate = 4800 baud
Data bits = 8
Parity = None
Stop bits = 1
Flow control = None
Make sure that the SD card is not inserted and that the logger is supplied with power. Connect
the logger to your PC via the RS-232 interface.
Press the “M” key on your keyboard. The following menu appears in the terminal program:

5.2 Read out the data
The data is stored on the SD card in Excel-compatible format. The logger creates a file for each
month which contains all reading of this time span.
Note: We recommend you to retrieve the data every month and keep backups of the data.
There are two ways of reading out the data.
5.2.1 Read out the data via SD card
Make sure that the logger is not storing any data at the moment (LED off) and then quickly remove
the microSD card.
Use a card reader to connect the SD card to your PC. On the SD card, you can find the monthly
files which contain the readings:
You can open the files with Excel. They contain the following parameters of each measurement:
Date: Date of this data, DD-MM-YY format
Time: Time that this data was recorded, 24h HH:MM:SS format
Direction: Wind direction (heading) in degrees (0º to 360º)
Temp C: Temperature in degrees Celsius (if NTC temperature sensor connected)
Wind1avg: Average wind speed in this interval for A1 input, meters/second (m/s)
Wind1max: Maximum wind speed recorded in this interval for A1 in m/s
Wind1std: Standard deviation of wind speed in this interval for A1 in m/s
Wind2avg: Average wind speed in this interval for A2 input, meters/second (m/s)
Wind2max: Maximum wind speed recorded in this interval for A2 in m/s
Wind2std: Standard deviation of wind speed in this interval for A2 in m/s
Batt V: Battery voltage
Note: If you set the sampling interval to 10 seconds, the logger creates files for each day.
However, to open these files in Excel, you need to use the Excel text import wizard.
The “log.txt” file contains all parameters of the configuration.

5.2.2 Read out the data via RS-232 interface
You can read out the data by using the RS-232 interface and a terminal program, too.
Depending on the sampling interval, data is transmitted to your PC. In the terminal program, the
data packets look as follows:
10-08-14,16:48:25,180,21.7,7.01,9.56,0.84,6.68,9.03,0.79,2.26
Interpretation:
10-08-14 Date in dd-mm-yy format
16:48:25 Time in 24h format
180 Wind direction in degrees, 180º = south. Value increasing clockwise in 16
steps
21.7 Temperature in degrees Celsius
7.01 Average wind speed (m/s) for A1 during measurement period
9.56 Maximum wind speed (m/s) for A1 during measurement period
0.84 Standard deviation for A1 during measurement period
6.68 Average wind speed (m/s) for A2 during measurement period
9.03 Maximum wind speed (m/s) for A2 during measurement period
0.79 Standard deviation for A2 during measurement period
2.26 Battery voltage. Note that 2.26 volts is very low and batteries should be
replaced.
If the LED flashes rapidly, a problem has occurred. If logger and PC are still connected you can
check if the logger is still working by using the terminal program. If data is still transferred, the
logger works fine, otherwise an error message appears.
ATTENTION: Always check if data is transferred and if the readings are fine before using
the logger on site.
Check the data by connecting the SD card to a PC or by using the RS-232
interface and a terminal program.
ATTENTION: Do not leave the RS-232 cable plugged in for a longer period of time because
this causes higher power consumption.

6 Troubleshooting
Problem: Data is not written to the memory card.
Solution: This is likely to be due to a corrupted memory card, excessive memory card
power consumption or flat batteries. Some memory cards use much more
power than others. To guarantee a long battery life, the logger limits the
current being supplied to the memory card. We recommend using the
memory cards supplied. The logger is compatible with microSD cards up to
2GB.
Problem: The time and date has reset to zero.
Solution: The logger uses the batteries to keep its internal clock working. If at any time
the batteries are removed, the logger will reset its time and date to 00. Follow
the instructions in chapter 5.1 to set the time and date.
Problem: The green LED is flashing continuously.
Solution: Make sure the memory card is inserted properly and the card is working
correctly. The logger is compatible with standard microSD cards up to 2GB.
Problem: Wind direction is stuck at zero.
Solution: Ensure that the wind vane wiring is correct and that there are no short circuits
or open circuits at the terminals. Check if the cable is damaged.
Problem: Wind speed is zero or incorrect.
Solution: Ensure that the anemometer wiring is correct and that there are no short
circuits or open circuits at the terminals. Check if the cable is damaged. Also
check if the anemometer type is set correctly as this affects the speed
calculations.
Problem: The batteries go flat quickly.
Solution: Ensure that the batteries are good quality alkaline type. These will last longer,
especially at low temperatures. Ensure that the microSD memory card is
inserted properly and does not have large amounts of data stored on it. Do
not use the 10-second logging interval for normal long-term logging, as this
uses more power. Make sure there are no short circuits in the sensor
connections and that the sensors are working correctly.
