Wind Direction and Wind Speed (Anemometer)
1. Open up the front panel to the 90 deg. position, as shown in Figure 4.5. Make sure the cable
supports the front panel securely.
2. Find a location that is open and free from obstructions. Mount the mast at the end of the greenhouse
or other building structure, with the top of the mast extending at least 3 feet above the top of the
building.
3. Run the free end of the sensor cable to the controller unit.
4. You may extend the sensor cable to a maximum length of 150, but make sure to use an adapter and
wire approved by Link4 to make any extensions (the wire and adapter can be purchased from Link4).
5. Carefully insert the cable through the right most watertight fittings at the bottom of the enclosure. It is
easy to strip insulation and/or break wires when pulling cable. If you want to bundle wires tighter, use
UV protected “tie wraps” (typically blue or black), and do not over-tighten.
Note: If any splices are needed to extend cable length, make certain they are WATERTIGHT. Water or
fertilizer infiltration WILL cause unstable sensor readings.
6. Keep sensor cables away from interference sources, including high voltage power wiring, inverters,
motor controllers, mercury arc, or sodium lamp circuits. Placing sensor cable near such wiring may
cause erratic sensor readings.
7. Connect the wires as shown in Figure 4.15.
8. After installing the sensor, it is recommended that sensors be checked by plugging in the power
supply and testing under various conditions before moving on in order to make sure the sensor works
properly and accurately. After testing remember to unplug the unit to continue installing other
sensors.
9. If necessary, refer to the Anemometer installation instructions that are shipped with the unit for more
installation details.
