Description

The P03/3-RS485-GPS/CET Weather Station measures temperature, wind

speed and brightness (eastern, southern and western sun). It recognizes precipita-

tion and receives the time signal with a GPS receiver. With the weather station P03/

3-RS485-GPS the international time signal UTC and position coordinates are out-

put. Direction (azimuth) and hight (elevation) of the sun are also calculated and

output. For the P03/3-RS485-CET Weather Station, the Central European Time

(CET) is output. The daylight savings time is adjusted automatically according to

the specifications for Central Europe.

The weather station sends the currently recorded weather data, date and time once

every second. This data flow can be received and analyzed by an end device such

as SPS, PC or MC.

Functions:

•

Brightness measurement with three separate sensors for east, south and

west. Recognition of twilight/dawn

•

Wind measurement: The wind strength measurement takes place

electronically and thus noiselessly and reliably, even during hail, snow and

sub-zero temperatures. Even turbulent air and anabatic winds in the vicinity

of the weather station are recorded

• Temperature measurement

•

Heated precipitation sensor (1.2 watts): No false reports as a result of fog

or dew. Dries quickly after precipitation has stopped

•

Sending cycle for data 1 second

Functions P03/3-RS485-GPS:

•

Integrated GPS receiver. Output of UTC (Universal Time Coordinated),

position (degree of longitude and latitude) and position of the sun (azimuth,

elevation)

Functions P03/3-RS485-CET:

•

Integrated GPS receiver. Output of CET (Central European Time),

automatic adjustment of daylight savings time.

Installation and commissioning

Installation, testing, operational start-up and troubleshooting should

only be performed by an authorised electrician.

CAUTION!

Live voltage!

• Inspect the device for damage before installation. Only put undamaged

devices into operation.

• Comply with the locally applicable directives, regulations and provisions

for electrical installation.

• Immediately take the device or system out of service and secure it against

unintentional switch-on if risk-free operation is no longer guaranteed.

Use the device exclusively for building automation and observe the operating ins-

tructions. Improper use, modifications to the device or failure to observe the ope-

rating instructions will invalidate any warranty or guarantee claims.

Operate the device only as a fixed-site installation, i.e. only in assembled condition

and after conclusion of all installation and operational start-up tasks, and only in

the surroundings designated for it.

Elsner Elektronik is not liable for any changes in norms and standards which may

occur after publication of these operating instructions.

2.0.1. Installation position

Choose an installation position in the building where wind, rain and sun can be

measured unhindered by the sensors. The weather station must not be installed

underneath any structural parts from which water can still drip onto the rain sensor

after it has stopped raining or snowing. The weather station must not be shaded

by anything, such as building structures or trees.

At least 60 cm of clearance must be left all round the weather station. This facilita-

tes correct wind speed measurement without eddies. The distance concurrently

prevents spray (raindrops hitting the device) or snow (snow penetration) from im-

pairing the measurement. It also does not allow birds to bite it.

Please take note that an extended awning does not shade the device from sun and

wind.

Temperature measurements can also be affected by external influences such as by

warming or cooling of the building structure on which the sensor is mounted, (sun-

light, heating or cold water pipes).

Magnetic fields, transmitters and interfering fields from electricity consumers (e.g.

fluorescent lamps, neon signs, switched-mode power supplies etc.) can interfere

with or even cut out reception of the GPS signal.

2.1. Mounting the sensor

2.1.1. Attaching the mount

The sensor comes with a combination wall/pole mount. The mount comes adhered

by adhesive strips to the rear side of the housing. Fasten the mount vertically onto

the wall or pole.

Different mounting arms are available

from Elsner Elektronik as additional, op-

tional accessories for flexible installation

of the weather station on a wall, pole or

beam (pictures of sensors exemplary).

Example of the use of a mounting arm:

Due to flexible ball joints, the sensor can

be brought into ideal position.

Example use of the hinge arm mounting:

With the hinge arm mounting, the weat-

her station projects from beneath the

roof overhang. Sun, wind and precipita-

tion can act upon the sensors without

hindrance.
