Testing the Anemometer

Before beginning your installation, follow the instructions below to test the ane­ mometer wind speed and wind direction functions.

1. Connect the anemometer cable to the appropriate connector on your sensor interface module {SIM) or junction box.

2. Push the wind cups onto the smaller of the two stainless steel shafts at the end of the arm.

3. Spin the wind cups gently You haven’t secured them yet, and if you spin them too hard you may knock them off.

4. Check the display on your weather station to make sure you are getting a wind speed reading.

5. Grab the larger of the two stainless steel shafts at the end of the arm with your fingers and twist the shaft about l /2 turn.

6. Check the display to make sure the wind direction readings on your display change.
   Note: The wind direction readings will not change as rapidly as you turn the shaft. The station uses a low pass filter to smooth out the constant small shifts in wind direction and keep the direction display from jumping about in gusty winds.

7. Disconnect the cables when you are finished testing the anemometer.

Assembling the Anemometer
Attach the drip rings and the wind cups to the anemometer and check the mounting base orientation before you install it. The wind vane is attached after the anemometer has been installed.

Attaching the Drip Rings

The anemometer drip rings provide protection against the icing of the wind vane and wind cups. Follow the instructions below to attach the two drip rings.

1. Place one of the drip rings on a flat surface with the small hole facing up.

2. Securely press the wind vane on top of the drip ring.
   Note: you may want to start with the vane tilted slightly

3. Make sure the ring fits securely between the two ridges on the vane with the lower edge parallel to the bottom of the wind vane.

4. Install the small end of the other drip ring on the wind cup end of the ane­ mometer control head as shown below.
   Note: The wind cup end of the control head has the smaller of the two stainless steel shafts.

5. Gently push up the drip ring until it reaches the groove on the control head.

6. Make sure the lower edge of the drip ring is aligned with the lower edge of the control head.

Attaching the Wind Cups
Before installing the anemometer, attach the wind cups. Wait until you have installed the anemometer before you attach the wind vane.

1. Push the wind cups onto the smaller of the two stainless steel shafts at the end of the arm.

2. Slide the wind cups as far up the shaft as possible.

3. Use the Allen wrench provided to tighten the set screw on the side of the wind cups.
   Note: When you let go of the wind cups, they should drop slightly.

4. Spin the wind cups. If they do not spin freely, loosen the set screw, lower the cups slightly, then retighten the set screw.

5. Repeat Step 4 until the wind cups spin freely.

Checking the Anemometer Base Orientation

You will need to know which way to orient the base before installing it.

1. Insert the anemometer arm into the base
2. Attempt to push the #4-40 x 1 1 /4″ pan head screw through the holes in the arm and the base as described in “Attaching the Wind Vane” on page 8.
3. If the screw does not slide easily through the holes, rotate the base 180 to line up the opposite holes, then try again.
4. Note the correct base orientation for use when you install the base later in the installation process.

Choosing the Best Anemometer Location
Use the following guidelines to determine the best location for your anemome­.

• Make sure you install the anemometer in a location where wind flow is unobstructed by trees and nearby buildings.

• For the most accurate readings, the anemometer should be mounted at least 4 feet (1.2 m) above the roof line.
  You may do this by mounting the anemometer on a television antenna mast, a wooden post, or a metal pipe.

• Make sure the antenna mast or metal pipe is properly grounded. You may want to useNetafimGrounding Kit.

• If you are not certain about how to ground your installation, consult a qualified professional for national and local codes.

Note: If you live in an area subject to frequent thunderstorms, installing a lightning rod nearby can reduce the risk of damage.

Installing the Anemometer

Use the following procedures to mount the anemometer.
Installing a Sensor Mounting Arm
Consult the Sensor Mounting Arm manual for instructions. You will need to return to this instruction manual after installing onto the Sensor Mounting Arm for instructions on attaching the wind vane (see “Attaching the Wind Vane” on page 8).

Installing the Base on a Wooden Post or Surface

1. Hold the anemometer base against the wood surface and use a pencil to mark the location of the four holes on the base.
2. Use a drill with a3/16 (5-mm) drill bit to make pilot holes in these locations.
3. Drive the lag screws through the holes in the anemometer base and into the wood.

Installing the Base on an Antenna Mast or Metal Pipe: Outside Diameter 7/8″ to 1 1/4″ (22 to 32 mm)

1. Hold the anemometer base against the pipe and insert the two U-bolts through the back of the base so that the U-bolts wrap around the pipe.
2. Place an l / 4 ·· washer and an I/ 4-20 hex nut over each end of the U-bolts and use a wrench to tighten the hex nuts.

Installing the Base on a Metal Mast or Pipe: Outside Diameter Greater than 11/4 inch (32 mm)
Use stainless steel hose clamps to attach the mounting base to masts or pipes larger than I L/4″ diameter.

1. Use two stainless steel hose clamps large enough to fit around the mast or pipe and the anemometer base.
   You may purchase hose clamps at your local hard­ ware store.

2. Hold the anemometer base against the pipe and fasten the hose clamps over the anemometer base and around the metal mast or pipe.

Attaching the Anemometer Arm to the Base

1. Insert the anemometer arm into the anemometer base.
   Guide the anemometer cable through the slot as you insert the arm.

2. Insert the pan head screw into one of the holes in the base and slide it through the arm.

3. Secure the pan head screw using the flat washer, and lock the washer. and hex nut as shown.

Attaching the Wind Vane
To mount the wind vane, you will need to look at the console display in order to orient the vane accurately. You may wish to have a friend or family member on the ground do this for you. Or, you may wish to bring the console and SIM/junc­tion box onto the roof with you.

1. Connect the anemometer cable to the SIM/junction box.

2. Press the WIND key on the console if necessary to display wind direction in degrees.

3. Use the compass or map to determine in which direction {N, S, E, W.) the anemometer arm is pointing.

4. Use the wind direction chart to find the degree reading which corresponds to that direction.

5. Slowly turn the wind direction shaft with your fingers. Stop turning when the weather station display reaches the degree reading obtained in step 4.
   Because of the low pass filter used by the station (see “Testing the Anemom­ eter” on page 2), the wind direction reading requires approximately 5 sec­ onds to stabilize each time you turn the shaft. You will need to turn the shaft, wait, and turn it again until you eventually “zero in” on the desired wind direction reading.

6. Being careful to keep the stainless steel shaft from turning, place the wind vane on the shaft with the bullet-shaped nose of the vane pointing in the same direction as the arm.

7. Slide the wind vane down onto the shaft as far as it will go.

8. Use the alien wrench provided to tighten the set screw on the side of the wind vane.

9. Test your assembly by pointing the wind vane in any direction and (using the compass or map as a guide) making sure the console displays the correct wind direction. Readjust the vane if necessary.
   Because of the low pass filter used by the station (see “Testing the Anemom­ enter” on page 2), you need to allow the wind direction reading approxi­ mately 5 seconds to stabilize after you turn the vane.

10. Spin the wind cups to make sure you get a wind speed reading. Readjust the cups if necessary.

11. Secure the cable to the metal mast or pipe with electrical tape. Secure the rest of the cable according to the directions below.

Securing the Cable
To prevent fraying or cutting of the anemometer cable where it is exposed to weather, it is very important that you secure it so it doesn’t whip about in the wind. Use cable clips or weather-resistant cable ties to secure the cable. Place clips or ties approximately every 3 to 5 feet (I to 1.6 m).

Note: Do not use metal staples or a staple gun to secure cables. Metal staples especially when installed with a staple gun–have a tendency to cut the cables

**Maintenance

**

Your anemometer does not require any regular maintenance.
CAUTION: DO NOT attempt to lubricate the wind cup shaft and bearings or the wind vane shaft. Natural or synthetic lubricants will inhibit the normal operation of the anemometer

**Troubleshooting

**

While your anemometer is designed to provide years of trouble-free operation, occasionally problems may arise. If you are having a problem with your unit, please check the following troubleshooting procedures before sending the unit in for repair. You will be able to solve many of the problems yourself. If, after check­ ing these procedures you are unable to solve the problem, please call Netafim Tech­nical Support for further instructions (see “ContactingNetafim Instruments
Technical Support” on page 11.) Please do not return your unit for repair without receiving prior authorization from Netafim Technical Support.
Wind speed reads O all the time or intermittently

• Make sure the anemometer cable is plugged into the jack marked WIND on the junction box.
• Check for a broken wire along the length of the anemometer cable. Carefully check areas where the cable has been secured.
• Try dropping the wind cups approximately 1/16″ to 1/8″ (1.5 to 3 mm) lower on the mounting shaft. Use the included Allen wrench to loosen and retighten the wind cup assembly.
• If you still do not get a reading, the problem is probably with the anemometer. Contact Netafim Technical Support for return authorization.

Wind speed reading seems too high or too low

• Check the installation by spinning wind cups. If the wind cups spin freely and your weather station displays a wind speed then the wind cups are installed correctly. If the wind cups don’t spin freely, then try dropping the wind cups approximately 1/16″ to 1/8″ (1.5 to 3 mm).
• Check calibration number and adjust if necessary.
• Check for any obstructions blocking the wind near the anemometer.
• The wind direction reading is dashed out
• Make sure the anemometer cable is plugged into the jack marked WIND on the junction box.
• Check for a broken wire along the length of the anemometer cable. Carefully check the places where the cable has been secured.

Note: If these steps do not solve the problem, the problem is probably with the anemometer Call Netafim Tech­nical Support for return authorization.
