1 Introduction
1.1 General
Thank you for purchasing a wind logger PCE-WL2 from PCE Instruments.
The wind logger PCE-WL 2 is used to determine and analyse the current wind situation before putting
wind energy plants into service. The wind sensor saves measured data on wind direction as well as wind
velocity to an SD memory card. This means that after the measurement, the data can be further analysed
by means of a PC. Its case is weather-resistant and protected according to the IP65 protection class. The
cable of the wind sensor is connected to the data logger via screwed connections. The wind sensor can
measure velocities of up to 40 m/s and wind directions of between 2.5 º and 357.5 º. The cup
anemometer of the wind logger is equipped with low-wear reed relays that ensure a long operating time.
Optionally, this device can be equipped with a display which indicates wind direction and velocity results
in real time.

4.1 Installation of hardware
4.1.1 How to open the case and install the cable
Open the case of the wind logger by loosening four screws at its corners by means of a screwdriver.
You can now see the circuit board of the data logger. The next step is to install the cable.
To do so, open the PG gland and remove the sealing ring.
First slide the nut over the wind sensor cable, followed by the sealing ring.

Now you can insert the cable into the case through the gland and fix the nut.
4.1.2 How to connect the sensor
The connector block of the sensors is fixed to the main circuit board. The connectors on the main circuit
board have the following functions:
From left to right:
G: ground
A2: input of sensor 2
G: ground
A1: input of sensor 1
G: ground
D: input of wind direction sensor
D+: power supply of wind direction sensor
V+: positive pole (red)
G: ground (black)

We recommend to use tweezers or long nose pliers for installation.
Note: The green and the green-yellow cable are not connected. We recommend to insulate the ends of
both cables.
4.1.3 How to mount the waterproof box to the wall
As there are 4 prepared holes, the PCE-WL2 can easily be mounted to a wall.
4.2 Power supply
The PCE-WL2 is powered by two 1.5 V D cells.
Note: Check on a regular basis whether the data logger still works properly und whether the batteries are
charged. Otherwise there might be some problems with the memory. We recommend to replace the
batteries every 3 months.
Attention: When replacing the batteries, date and time are reset. You have to make the date and time
setting again.
We recommend to make a backup of the SD card on another SD card. Before replacing the batteries,
make all SD card settings by means of the configuration software. Replace the batteries and insert the
newly configured SD card. The new settings will then be saved directly to the data logger.
5 Instructions
5.1 Device status
The current device status is indicated by a green LED inside the device.
Manual
8
LED off: The logger is in normal data storage mode. The LED flashes in the recording interval you set up.
If the set interval is 10 seconds, the LED flashes every 10 seconds. If the set interval is 1 minute, the LED
will flash every minute.
LED flashes quickly: There is a memory card error. One possible reason is that the memory card has
not been inserted correctly but it is also possible that the power consumption of the memory card is too
high to ensure proper recording.
Quick flashing can also indicate that the wind logger is ready for communication via the RS-232 interface.
LED on: The logger is in setup mode and settings must be made by means of a computer connected to
the device via the RS-232 interface.
5.2 Setup of the wind logger PCE-WL2
5.2.1 Setup of the data on the SD card by means of the software (for beginners)
Remove the SD card from the data logger and connect it to a PC by means of a card reader.
Start the file lewl_setup.exe. The following window will open:
Manual

After making all settings, click on the “Write setup file” button to save the settings. You can now remove
the SD card from the PC and insert it into the logger again. Data storage will start automatically. The
flashing LED in the set recording interval indicates that the wind logger works properly.
5.2.2 Setup by means of the terminal programme (for experts)
The PCE-WL2 data logger has an integrated menu which can easily be configured by means of a
terminal programme via a PC. All parameters (except date and time) are saved to the device permanently
and so not have to be set every time.
Note: PCs which are equipped with Windows 7 do not have an integrated terminal programme. As a
replacement, we recommend the programme HTerm by Tobias Hammer which is freely available.
5.2.2.1 Connection to a PC
In order to carry out the configuration of the device, open the terminal programme and connect the device
with the following parameters:
1. the COM port you use
2. baud rate: 4800
3. 8 data bits
4. no parity
5. 1 stop bit
6. no flow control

5.3 How to read out data from the memory card
When you want to remove the card from the device, make sure that no data are saved to the SD card at
that moment, which is indicated by the LED flashing in the recording interval. In order to start data
recording again, you only have to insert the memory card into the device again.
The data saved on the memory card can easily be read out on the PC by means of a memory card
reader. If the recording interval is 10 seconds, the record files are listed on the basis of the date.
Example: The file 01-10-08.CSV contains all data recorded this day:
If the recording interval is 1 or 10 minutes, the files are listed on the basis of the month:
The file LOG.TXT contains all configuration parameters: date, time of configuration, recording interval and
number of sensors:
16-10-08, 17:16:51, Avg_time=10, Sensor1=1.05999994, Sensor2=1.05999994
