How to install and operate FYF-A intelligent wind direction and speed alarm：

Please refer to the front and rear panel diagram of the FYF anemometer host on the next page.

This instrument is powered by mains electricity. Before use, confirm that the power supply for the instrument is 220 × (1 ± 15%) VAC 50Hz, and the capacity of the fuse in the fuse holder on the back panel of the instrument is 0.

The sensor of the instrument is connected to the circular sensor plug socket on the back panel of the host through a cable, and the power cord is reliably connected to the mains power supply. The grounding protection wire of the instrument is properly connected to the ground (i.e. the ground wire in the single-phase 220V three core mains power supply should be reliably grounded).

Turn the boat shaped power switch on the rear panel of the host to the on position, and the instrument will be put into operation. Before the instrument is officially measured, all the light-emitting diodes on the instrument panel and all the light-emitting segments on the digital tube flash for about three seconds to check whether the instrument's light-emitting tube and digital tube are intact.

After power on, the instrument automatically enters the display mode of 3-second average value, which is the gust parameter. The 'Real time' indicator light is on, indicating that the real-time wind parameters are currently displayed. The '3-second' indicator light is on, indicating that the 3-second average value is currently displayed. The wind speed digital display shows the gust wind speed, the wind direction digital display shows the gust wind direction, and the disc display shows the gust wind direction in azimuth (32 azimuth resolution).

Press the "Average Time/+1" button, and the "3 seconds" indicator light will turn off, while the "2 minutes" indicator light will turn on, indicating that the current display has been changed to the average wind parameter of 2 minutes. Due to the display cycle, replacement of the display may take 1-3 seconds

Press the "Average Time/+1" button again, and the "2 Minutes" indicator light will turn off, while the "10 Minutes" indicator light will turn on, indicating that the current display has been changed to the average wind parameter of 10 minutes.

When the average values of 3 seconds, 2 minutes, and 10 minutes are displayed, if the "Average/Extreme/-1" button is pressed, the "Extreme" indicator light on the panel will light up. At this time, the wind speed digital display will show the gust wind speeds that occurred in the past 3 seconds, 2 minutes, and 10 minutes, respectively. The wind direction digital display and the disk wind direction display will show the corresponding wind direction when the gust occurred.

To change the setting value of the wind speed warning, press the "Work Mode" button. At this time, the "Real time" indicator light will turn off, while the "Settings" and "Warning" indicators will light up to indicate entering the setting state of the warning wind speed setting value. The wind direction digital display will show zero, the disc display will turn off, and the wind speed digital display will show the internal wind speed warning value. Use the "Average Time/+1" and "Average/Extreme Value/-1" buttons to increase or decrease the wind speed warning value. When the changes are correct, press the "Working Mode" button, and the instrument will enter the setting of the alarm wind speed setting value. The "Pre alarm" indicator light will turn off and the "Alarm" indicator light will turn on. The instrument enters the setting state of the alarm wind speed setting value, and its operation is similar to the setting of the warning value. After setting the alarm value, press the "Working Mode" button again to indicate the alarm value and return the instrument to real-time measurement mode. The "Settings" and "Alarm" indicator lights are off, and the "Real time" indicator light is on. At this point, the pre-set warning and alarm values are also stored in the system's EEPROM, which can be saved even after the instrument is powered off. They can be automatically restored the next time the power is turned on, without the need to reset them unless the original settings need to be changed.

When setting, the warning value should be set to be less than the alarm value.

When the gust wind speed is greater than the set warning wind speed, the "Warning Warning" indicator light will turn on and the instrument will give a warning signal. If the wind speed of the array further increases, when it exceeds the set value of the alarm wind speed, the "Alarm" indicator light will turn on, and the instrument will give an alarm signal. The warning signal will only disappear and the warning indicator light will turn off when the gust wind speed is lower than the set warning wind speed. Control relays can be installed according to user requirements, and the contacts of the relay can be used to control the user's equipment when warning and alarm signals occur.
