Safety Instructions

• Before operating with or at the device/product, read through the operating instructions.
This manual contains instructions which should be followed on mounting, start-up, and operation.
A non-observance might cause:

- failure of important functions

- Endangering of persons by electrical or mechanical effect

- Damage to objects

• Mounting, electrical connection and wiring of the device/product must be carried out only by a qualified technician
who is familiar with and observes the engineering regulations, provisions and standards applicable in each case.

• Repairs and maintenance may only be carried out by trained staff or Adolf Thies GmbH & Co. KG. Only
components and spare parts supplied and/or recommended by Adolf Thies GmbH & Co. KG should be used for
repairs.

• Electrical devices/products must be mounted and wired only in voltage-free state.

• Adolf Thies GmbH & Co KG guarantees proper functioning of the device/products provided that no

modifications have been made to the mechanics, electronics or software, and that the following points are
observed:

• All information, warnings and instructions for use included in these operating instructions must be taken into
account and observed as this is essential to ensure trouble-free operation and a safe condition of the measuring
system / device / product.

• The device / product is designed for a specific application as described in these operating instructions.

• The device / product should be operated with the accessories and consumables supplied and/or recommended

by Adolf Thies GmbH & Co KG .

• Recommendation: As it is possible that each measuring system / device / product under certain conditions, and
in rare cases, may also output erroneous measuring values, it is recommended using redundant systems with
plausibility checks with security-relevant applications.

• As a longstanding manufacturer of sensors Adolf Thies GmbH & Co KG is committed to the
objectives of environmental protection and is therefore willing to take back all supplied products

governed by the provisions of "ElektroG"

and to perform environmentally compatible disposal and recycling. We are prepared to take
back all Thies products concerned free of charge if returned to Thies by our customers
carriage-paid.

• Make sure you retain packaging for storage or transport of products. Should packaging
however no longer be required, arrange for recycling as the packaging materials are designed
to be recycled.

3 - 12 021262/11/07

The wind direction transmitters are shipped in semi-mounted state, in order to avoid transport
damages and to keep the package small.

The following parts are included in delivery:
1 x wind direction transmitter, pre-mounted
1 x cup star
1 x wind vane
1 x connecting plug

2 Range of application

The wind direction transmitter is designed for the acquisition of the horizontal wind direction. The
measuring value is output proportionally to wind direction as analogue voltage in case the
potentiometer is supplied by a constant voltage. The measuring data available are ideally adapted
to the supply in display instruments, recording instruments, datalogger, as well as process control
systems.

For winter operation the instruments are equipped with an electronically regulated heating in order
to guarantee a smooth running of the ball bearings, and to avoid ice-formation at the slot of the
outer rotation parts. The electrical supply of wind transmitter heating is carried out, for ex., by our
power supply unit, order-no. 9.3388.00.000.

3 Construction and Mode of Operation

The housing and wind vane are made of aluminum, die the surfaces are anodized. Labyrinth seals
and o-rings protect the sensitive internal parts from precipitation. The instrument is designed for
mounting to a mast tube; the electrical plug connection is situated in the transmitter shaft.

The wind direction is detected by means of a low-inertia wind vane, the ball bearing axis of which is
connected to a potentiometer.

4 Recommendation Site Selection / Standard Installation

In general, wind measurement instruments should be able to detect wind conditions over a broad
range. In order to obtain comparative values of the surface wind, measurements should be taken at
a height of 10m above a flat, open terrain. Open terrain means that the distance between the wind
transmitter and an obstacle is at least 10 times greater than the height of the obstacle itself. If this
requirement cannot be fulfilled, then set the wind transmitter up at a height where the influence of
local obstacles on the measured values is minimal (about 6-10 m above the level of the obstacle). If
the wind transmitter is set up on a flat roof, then place it is the center of the roof and not at the edge
in order to avoid privileged directions.
