SENSOR MAINTENANCE
Wind sensors experience vibration due to high velocity wind. The vibration can loosen the mounting
screws or the support structure. Regular inspection of the mounting hardware is required to prevent
damage to the sensor.
1.
Inspect the wind vane to ensure the tail is vertical and the screws holding it to the vane are
snug. If the vane has loosened then it must be re-balanced before tightening. First, inspect the
counterweight to ensure it is firmly cemented to the vane. Repair if necessary. Next, remove
the entire sensor and hold it horizontal to the ground. Adjust the distance of the counterweight
until it exactly balances the tail. Make sure the tail is vertical to the sensor and then tighten the
vane. Re-check the balance.
2.
With the sensor mounted on the mast make sure the North
indicating label is oriented
correctly, then tighten the mounting screws (do not strip the threads in the plastic base of the
sensor).
3.
Spin the anemometer cup assembly. It should turn freely. A short spray of light oil such as
WD40 can be applied to the bearing located in the hub of the cup assembly.
4.
Inspect the cable and ensure it is secured to the mast to prevent damage due to wind whipping.
5.
A repair kit (Part number 200-WS-02E-ASSY) is available in case one of the cup arms is broken.
