Operating and installation instructions
Wind direction sensor
Keep for future use
Valid from 15 November 2009
General information
Note on electrical installation
The unit is electrically connected as shown in Fig. 3. Connect the supplied plug-in connector to your line. The line
may have a length of up to 50 m. If you received wiring
diagrams for your particular sun shading control unit, also
follow the connection instructions in these documents.
The sensor may only be operated with safety extra low
voltage. As specified in VDE 0022, the operating company and the installer are responsible for compliance with
the regulations put forth by the public utility provider and
the VDE.
The device meets the EMC directives for use in residential
and commercial areas.
Fig. 1: Wind direction sensor
The sensor is connected to the SE-BII sensor unit and,
together with the "Wind" (type 3H) sensor, is used to
measure the horizontal component of the wind direction.
The sensor can be mounted outside on a pole. The high
quality, die cast metal design and the integrated heating
guarantee a high resistance to weathering. The precision
ball bearings ensure that it provides immediate measurements, even in light winds.
Installation
When installing the sensor, note the following instructions:

The sensor must be mounted in the immediate vicinity
of the "wind" sensor

Ideally, the sensor should be mounted at a height of
approx. 10 m above a level, undisturbed terrain. Undisturbed terrain means that the distance between the
sensor and obstacles should be at least ten times the
height of the obstacle. On flat roofs, the wind direction
sensor should be erected in the middle of the roof instead of at the edges to avoid preferential directions.

First mount the wind vane on the sensor housing.
Slide the supplied rubber disk (Ø 17 mm) over the
axis. The counterweight of the wind vane is equipped
with a pin (Ø 3 mm); place the wind vane on the axis
so that the pin engages in the corresponding hole.
Fasten the wind vane using the self-locking cap nut.

To achieve a northward orientation, the housing markings on the shaft and on the protective cap are moved
into alignment. Then a prominent feature in a northerly
direction is identified using a compass. The equipment
is then aligned with this point using the guide plate
and rod of the wind vane. When they are aligned, the
sensor is fixed to the pole using the two hex screws.
Intended use
The device was developed to control sun shading systems. The approval of the manufacturer must be obtained
for uses outside of the purposes listed in these instructions.
Safety instructions
WWARNIN
The electrical installation must be performed
by a certified electrician in accordance
with the electrical installation regulations
published by the Association of German
Electrical Engineers (VDE 0100) or the
standards and regulations of the country
in which the device is being installed. The
specialist must observe the installation
instructions included with the electrical
device.
WWARNIN
If it appears that hazard-free operation is
not possible, the device may not be started
or must be deactivated. This assumption is
justified

If the housing or the supply lines show signs
of damage,

If the device is no longer working.

CCAUTIO
The equipment may only stored, mounted
and operated in the open in a vertical
position as otherwise water may enter into
the device.
Commissioning
After the device is fully mounted and the power supply is
connected, the device is ready for operation.

Function
Technical data
The wind vane is turned by the wind. The magnetic direction scan generates an encoded signal that is converted
to an analogue signal by an integrated measurement
value converter. The operating and heating voltage is
supplied by separate power supply units. The device can
therefore also be operated without heating. Outputs and
inputs are protected against overvoltage.
Sensor for
wind direction
There are no parts within the device that require maintenance. The sensor should occasionally be checked for
dirt (e.g. bird droppings) and cleaned carefully. Commercially available household cleaners may be used. Solvents may not be used.
Liability
Failure to comply with the product information in these
instructions and use of the unit in a manner that contravenes its intended use and purpose may result in the
manufacturer refusing to honour warranty claims for product damage. In this case, liability for consequential harm
to persons or damage to property will also be excluded.
Follow the instructions in the operating instructions of your
sun shading system. The automatic or manual operation
of the sun shading system when iced over as well as using the sun shading system during severe weather may
cause damage and must be prevented by the user by taking suitable precautions.
