200- WS-23 Wind System BENCH TEST Testing Procedure

WS-02F Wind Sensor Testing .................First the WS-02F sensor needs to be tested for proper operationYou Will Need a Simple Digital Multimeter

To test the Wind Speed output Connect an ohmmeter to the Brown and White wires. It will read an open or closed , when you rotate the cups The ohmmeter will show 3 switch closures in one rotation on the cups

To test the Wind Direction on the sensor to verify if it is Defective ... Do the following....1. You will need an ohmmeter set to measure around 20K Ohms2. Measure the Resistance Between the between the Black and Red wires It should be around 20 K ohms3. Now Measure the Resistance Between the between the Black and Green wires now rotate theDirection Vane around one full Rotation, it should vary form 0 to 20K ohms ( If the sensor tested good then proceed to the next step to test the PCB )

SENSOR TO PCB Connection Connect Wind Sensor As shown belowmake sure that there is a good connectionand you are not Screwing down on the wireinsulation.

Refer to WS-23 Manual Drawings also.

Now You can Test to PCB with the Sensor connectedYou will Need a DC power source and a digital multi-meter that is set to measure dc current.

The DC power should be between 9 to 30 volts DC for our testing we used a 9 volt battery for simplification

Step1. Connect the positive from the power source to number 1 and 3 on the green 4 pin terminal A jumper wire can be connected to terminal 1 & 3 they are labeled WD+ & WS+ on the board.

Step 2. Connect the positive lead from your Current meter to number 4 to the terminal is labeled WS -

Step 3. Connect the negative lead from your Current meter to the negative on the DC Power Source.

Step 4. It must indicate 4 milliamps on your Current meter, If it does not then the board is defective 4 ma is equal to 0 mph wind speed.

Now Spin the cups by handand the 4ma signal willincrease to 5 or 6 ma

Step 5. Move the positive lead fromyour Current meter to number 2 tothe terminal is labeled WD -

Step 6. Leave the negative leadfrom your Current meter connectedto the negative on the DC PowerSource.

Step 7. If the Wind Vane is pointedto the West It will indicate around 16milliamps on your Current meter

South be 12ma, & East at 8ma
