Getting started

4.1 Assembly
Attach the wind speed alarm controller where desired. The dimensions can be taken from the assembly drawing below.

4.2 Power supply
Establish power supply by means of the relevant connections and set up the connection of the relay outputs to your system or signalling device (see 3.2). Make sure that the polarity and the power supply is correct.
ATTENTION: Excessive voltage can destroy the device! Ensure zero voltage when establishing the connection!
The device will power on immediately when connected to the power supply. The current reading will be displayed when a sensor has been connected. If no sensor has been attached, the display will show “00,0“ if you have one of the PCE-WSAC 50-A2C versions (signal input 0…10 V) or.
“Err“ if you have a PCE-WSAC 50-A1C version (Signal input 4…20 mA).
4.3 Connecting the sensors
Connect the sensor (not included in the standard package) and the (optional) interface, using the plugs as described in 3.3 and 3.4. Make sure that the polarity and the power supply are correct.
ATTENTION: Non-observance of the polarity can destroy the wind speed alarm controller and the sensor.

Operation

5.1 Measurement
The device measures continuously as long as it is connected to the power supply. The factory default setting for the pre-alarm (S1) is from 8 m/s and for the alarm (S2), the default setting is from 10.8 m/s.
The pre-alarm will make the pre-alarm relay switch, a yellow LED will glow and a beep sound will be emitted in intervals.
In case of an alarm, the alarm relay will switch, the red LED will glow and a continuous beep sound will be activated.
5.2 Settings
To get to the setup menu, press the ENTER key (6) until the first digit flashes. Then enter “888“.
With the Arrow right key (7), you can navigate through the digits and change the value of the digit with the Arrow up key (8). Confirm with ENTER (6).
The following options can be selected using the Arrow up key (8):

with the Arrow right key (7) and change the value of the digits with the Arrow up key (8). Confirm with ENTER (6).
Please note: The pre-alarm value must not be higher than the alarm value and the alarm value must not be lower than the pre- alarm value.
S2| Alarm| Enter the desired value (max. 50 m/s). You can move the cursor with the Arrow right key (7) and change the value of the digits with the Arrow up key (8). Confirm with ENTER (6).
Please note: The pre-alarm value must not be higher than the alarm value and the alarm value must not be lower than the pre- alarm value.
Flt| Filter| You can use the Arrow right key (7) to navigate through the digits and the Arrow up key (8) to change the value of the digits. Confirm with ENTER (6).
The following options can be selected: “000“ Current wind speed
Change interval of display:    200 ms Change interval of relay:        200 ms
“002“ 2-minute average value Change interval of display:    120 s Change interval of relay:        120 s
“005“ 5-minute average value Change interval of display:    300 s Change interval of relay:        300 s
Str| Factory settings| Resets all parameters to factory settings

To enter the relevant menu, select the menu with the Arrow up key (8) and confirm with ENTER, (6).
You can leave the menu by selecting “Ext“ and confirming with the ENTER (6) key. If no key is pressed for 60 seconds, the device enters normal measuring mode automatically.
6 RS-485 interface (optional)
The communication with the wind speed alarm controller PCE-WSAC 50 is enabled by the MODBUS RTU protocol and the serial RS-485 port. This allows different registers containing the measured wind speed, the wind scale and other information to be read.
6.1 Communication protocol

• The registers can be read by means of the Modbus function 03 (03 hex) and written into by the function 06 (06 hex).

Supported baud rates| 1200, 2400, 4800, 9600, 14400, 19200,
38400, 56000, 57600, 115200
---|---
Data bits| 8
Parity bit| None
Stop bits| 1 or 2
Data type of registers| 16-bit unsigned integer

6.2 Standard setting

6.3 Excerpt from register addresses

Register address (dec)| Register address (hex)| Description| R/W
---|---|---|---
0000| 0000| Current wind speed in m/s| R
0001| 0001| Current wind scale| R
0034| 0022| Pre-alarm| R/W
0035| 0023| Alarm| R/W
0080| 0050| Modbus address| R/W
0081| 0051| Baud rate (12 = 1200 baud, 24 = 2400 baud,etc.)| R/W
0084| 0054| Stop bits (1 or 2)| R/W
