3. 1 4 Custom North point setup The wind vane should normally be mounted with its index marker facing North In this case the LeWL does not need any wind direction calibration For installations where it is not possible to mount the vane facing north the Reset North Indexing option must be used to calibrate the North direction To set the North calibration select Yes and write the setup file as normal Before inserting the SD card into the LeWL and powering up the LeWL manually point the vane to North and hold it there Then insert the card and power up the LeWL and it will apply the north calibration NOTE After North calibration is done make sure this option is set to No in future to avoid re calibration when the wind vane is in operation The LeWL will automatically change this part of the setup file but is good practice to check it You can also use the Serial Port to perform the North calibration 3 3 1 5 Applying the settings to the LeWL After selecting and setting up all the parameters for the LeWL the final step is to write the setup file to the SD card Click the Write setup file button and the parameters will be written to the setup txt file on the SD card You can verify the selected parameters for the LeWL by viewing the setup txt file on the SD card after clicking the Write Setup file button Installation Manual Page 17 Logic Energy Ltd Installation and Setup After the new setup file
