Mounting dimensions
Unit: mm Installation
1.Ensure that the input voltage is correct.
2. Ensure mount face is flat.
3. Fix product to mount face by using four nos. M5 screws(not
provided), ensure mount face is flat and has enough mechanical
strength.
4. Remove screws from front cover, see terminal blocks.
5. Insert the cable through cable gland, correctly connect power
line, data line and control line and control line to terminals
according to the indication tags on wires (wiring diagram is provide
on the left).
6.Product start to operate when power on, display wind data when
wind speed sensor is operating.
7. To prevent short circuit, fix well the unused terminals.
Wiring diagram
Wiring connection:
it is recommended to use RVVP/4 core/0.5mm²/copper core/high
and low temperature resistant shielding cable
Caution
1. Ensure cable connection is correct before power on
2. Cable shield layer and housing must be well grouded.
3. Manage and fix wind speed sensor cables well.
4. Indoor application, work with UART signal wind speed sensor only.
RS485 protocol
1. Baud rate: 9600 bit/s, 8 bit data, no parity check, one stop bit .
2.Data definition: auto-output a frame per 1s, total 7 bytes.
0xAA 0x04 0xXX 0xXX 0x00 0x00 checksum
3. Byte definition: 0xAA is synchronoushead, 0x04 is message
length, next 0xXX bytes combine a word which indicate wind
speed, the next two bytes are useless, checksum =
0xXX+0xXX+0x00+0x00, indicate checksum.
4. For example: 0xAA 0x040x01 0x6A 0x000x6B
Wind speed is 0x016A = 36.2m/s(data is binary number, convert
to decimal number indicate wind speed)
Checksum is 0x6B=0x01+0x6A+0x00+0x00
Caution:
RS485 interface is standard 9-pin DB9 connector. Foot 1 is A line of RS485, foot 2 is B line, the others are useless.
Operating and Debugging
1. Wirelesserror：
FA221C display wind data when FA221C and FA231W connected, if display”_ _ _”, go to check the connection, ensure no obstruct objects.
2. Mode and parameter setting:
1) A is wind speed and scale: A00.0 is wind speed (see fig.1), A10.0 is wind scale (see fig.2).
2) b is Pre-alarm setting: For example, if display “b18.0“, wind speed indicator is lit up, wind speed is 18m/s (see fig. 3). When wind speed
or wind scale reach the set value, product output pre-alarm signal, built-in buzzer start to alarm, frequency is 1HZ.
3) C is Alarm setting: For example, if display “c09.0“
, wind scale indicator is lit up, wind scale is 9 (see fig. 4). When wind speed or wind
scale reach the set value, product output alarm signal, built-in buzzer start to alarm, frequency is 2HZ.
4) d is wind speed range: For example, if display”d50.0”, it means wind speed range is 0-50m/s (see fig.5)
If wind speed range is linearly proportional to wind speed 0-50m/s, please set d mode as „d50.0“
If wind speed range is linearly proportional to wind speed 0-30m/s, please set d mode as „d30.0“
5) Mode setting (Automatic return to normal mode and don’t save changing data if no action within 10 seconds in SETTING mode.)
Mode A: Press the SET button for 3 seconds untill digit A flash.
Mode b: When character C or A is flashing, shore press ▼or ▲unitl digit b flash.

3| 4datasheet-FA221C-1704-en.1.1
FA221C Wireless Wind Data Display
Mode C: While character A or b is flashing, shore press ▼or ▲unitl digit C flash.
Mode d: While character A or C is flashing, shore press ▼or ▲unitl digit d flash.
6) Parameter setting (Switching wind speed to wind scale is not linear, wind speed number has a little change when switch wind speed to
wind scale.)
(In mode setting, short press and move the cursor to the required position, then short press ▼or ▲
to change the number, when the
setting is compeleted, press SET button for 3 seconds to save and quit.)
3. Wind direction setting
Product displays 16 wind direction. In normal mode, press a second, enter into wind direction mode, it displays 0~359
degree and 16 wind
direction; press a second again, quit wind direction mode, return to normal mode (see fig. 6).
3. Setting timing system and checking
Time service is used for SD card data logger; there is no need to set when you do not request record data.
If require data logger, power interrupts over 6 months or used in another time zone, please set the time.
Manual or auto set time (auto set should only be achieved by NANHUA’s software)
Manual set process:
1) Under A mode & inputting password “A16.3”, turns to time set and shows access time.
2) Under time set mode, displays “1—12”,and “1” flashes, which means year-2012
3) Then press▲, displays “2—02”,and “2” flashes, which means month-February;
4) Then press▲, displays “3—24”,and “3” flashes, which means date-24th
5) Then press▲, displays “4—13”,and “4” flashes, which means H-13;
6) Then press▲, displays “5—58”,and “5” flashes, which means Min-58
7) Then press▲, displays “6—26”,and “6” flashes, which means Sec-26
8) Press ▲or▼, you can re-check the time. Once the tolerance is over 3 mins, please revise the time; otherwise wait 10s and quit.
9) Setting device timing system, short push to move cursor, short push ▲or▼
to revise data, finish setting push SET button 3S to save
and quit.
SD card data logger:
1) Under normal mode and SD card inserted, the displayer will take sample with 10s interval and store it into SD card per 20 mins and so
forth.
2) SD card storage format:
★Total folder “WINDYDAT”under SD card directory
★Year folder “YEAR20xx” under“WINDYDAT”
★Monthly folder “MONTHxx” under “YEAR20xx”
★Day folder“DAYxx.TXT” under“MONTHxx”
★Each day’s data stored under “DAYxx.TXT”. Ex. 15:01:30 167 230 means the wind speed is 16.7m/s and direction of 230°at 15:01:30 of
that day.
3) SD card Operation and troubleshooting:
★Once the SD card extracted, the displayer screen will flash 4 times with buzzing, which mean the SD card is extracted.
★Once the wrong SD card inserted, the displayer screen will flash 4 times with buzzing, which means the SD card faults.
★If the normal SD card inserted, the displayer screen will not flash but alarm once, which means the SD card is right.
★SD card problems and solutions:
①SD card write-protection: unlock the SD card write-protection.
②SD card capacity less than 30M: ensure the capacity is over 30M.
③Before SD card used, please format it as FAT32 file system.
④If the SD card meets above requirements but the displayer also shows SD card fault, please re-start the displayer.
4) SD card and principal computer analysis software:
★Attached 4G standard SD card.
★4G SD card has store FA220S computer analysis software, software manual, USD to RS485 UT890 driver software.
