The "Si" (silent) switch determines whether the internal buzzer operates. The normal setting is
OFF which allows the buzzer to operate. The ON setting silences the buzzer.
The controller checks the positions of the DIP switches when the unit initializes during power-up. It is
necessary to disconnect the AC Adapter for a few seconds and then re-connect power for the unit to
change modes.

ANEMOMETER INSTALLATION
WARNING: Avoid overhead power lines whenever possible. If there are overhead power lines, use
extreme care to prevent contact with the power lines while installing the equipment. NovaLynx
recommends using only experienced equipment installers to avoid injury.
5.1
Anemometer Siting Considerations
Choose a mounting location for the wind sensor that is free of obstructions since nearby objects can
create eddy currents that will affect the wind measurements. Try to locate the wind sensor so that the
nearest object is 10 x T away from the wind sensor mast, where T is the height of the object.
Roof mounted sensors should be placed on the upwind side of the building and away from all exhaust
vents. If the sensor is located on top of a building the sensor height should be 1.5 x H, where H is the
height of the building.
In all cases when the wind sensor data is to be correlated to National Weather Service data or World
Meteorological Organization data, the standard exposure is 33 feet (10 meters) above the ground.

Anemometer Mounting
CAUTION: Always be careful when working on equipment that is mounted above you. Do not allow
others to stand below when equipment is being installed as falling objects can be hazardous.
The 200-WS-01B anemometer is often mounted to the top of the supporting mast. A mounting arm
(Part number 200-153) is available for mounting to the side of the mast or tower. The base of the
sensor accepts ¾" IPS pipe size or any other 1" to 1-1/16" (25 to 27 mm) outside diameter pipe.
The mast should be easy to reach for servicing the sensor and should be properly anchored and
grounded. A tilt-down arrangement can eliminate the need for lifts or ladders during installation and
service.
If the supporting mast or tower is metal it should be properly grounded to minimize lightning damage.
Installations where nearby lightning strikes are likely should include a properly grounded lightning rod
