merten 580692 Wind Monitoring Unit Sensor
What you can do with the wind monitoring unit
The wind monitoring unit enables the blinds to be raised or lowered depending
on the wind strength. The Up position protects fragile blind slats, thereby
maintaining safety in windy weather.
The wind monitoring unit consists of two components:
- a wind sensor (art. no. 580692) or a wind sensor with heating (art. no. 580690) and
- the wind sensor interface.
The wind sensor is operated in connection with the blind control insert and the binary inputs of the KNX system.
Risk of fatal injury from electrical current. The device may only be installed and connected by skilled electricians. Observe the country-specific regulations.
Installation notes
The required screws and plugs are included with the delivery.
Installing the wind sensor, wind sensor with heating
The wind sensor (art. no. 580692) or the wind sensor with heating (art. no. 580690) is installed on the roof or the outside wall of the building. It must be mounted in a position suitable for measuring the wind strength. The device must therefore not be mounted in the slipstream of any objects. Ensure that the device is mounted in the correct position. Use a shielded wire for the wind sensor connection (we suggest: JY-ST-Y 2x2x0.6). Do not lay the cable together with 230 V wires (risk of interference).
Connecting the wind sensor interface
The wind sensor is connected to the blind control insert using the wind sensor interface.
- Remove the lid of the connection housing by removing the two screws. (If the cable entry is at the back, pierce through the rubber grommet and insert the wire).
- Secure the device using two screws.
- Insert cables into the connection housing and connect them as shown.
The wind sensor interface is equipped with floating make contacts. For use at the same phase, install a bridge between L and When low.
voltage circuits are connected to the floating make contact, observe the VDE 0100 regulations.
Selecting the wind sensor
Two different types of wind sensors can be connected. Set the switch to
position II (factory setting).
Selecting test mode/wind strength evaluation
Moving the rotary switch into one of the ten positions (1, 2, 3, … 9, 0):
- activates the test mode (positions 1 and 2).
- defines the wind strength at which the blinds are raised (position 3 – 0).
Test mode
Positions 1 and 2 activate the test mode: The optical display (test LED, lights up after a maximum of one second. If the rotary sensor is rotated, the test LED flickers at the frequency of the rotational speed and one can test that the unit is working even when the rotational speed of the rotary sensor is low.
Wind strength evaluation
Position 3 – 0 defines the wind strength at which the blinds are raised. The
setting is made in Beaufort (Bft) units, see. After exiting the test mode, it
takes the unit about 4 seconds for the device to evaluate the set wind force.
The selected setting will be applied after a maximum of 4.5 minutes after
switching from one wind strength to another. In order to quickly switch over
from one wind strength evaluation to another, select the test mode and then
set the desired wind strength. Terminals 1 and 2 serve as distributor
terminals and are not wired inside the unit. They can be used for a wind
sensor with heating, for example. The individual distributor terminal is used
to connect the protective conductor. Close the lid of the unit.In order to
