Figure 4: Connection diagram for connecting the evaluation unit to the Venetian blind controller
oThe evaluation unit has a relay with two potential-free NO contacts. To control the Venetian
blind insert (11) from the same conductor, place a bridge (12) between the relay input and
the conductor.
oCarry out commissioning (see Commissioning chapter).
oClose the housing lid of the evaluation unit.
iIf 230 V is present at extension input 2 of the insert (11), then the blind/shutter moves to
the top end position and cannot be operated, either manually or automatically.
iGlass break sensors may not be used jointly with the wind sensor. After there is a glass
break, the wind alarm function is locked and the Venetian blind or roller shutter does not
move to a safe end position.
4.2 Commissioning
DANGER!
Electrical shock when live parts are touched.
Electrical shocks can be fatal.
Before working on the device, cover up live parts in the working environment.
Setting the wind sensor switch in the evaluation unit
oOpen the housing lid of the evaluation unit.
oTurn the rotary switch to the (8) to the II position, factory setting (Figure 3).
Carrying out test operation
The rotary switch (9) specifies the wind speed at which the blind/shutter moves up or activates
the test operation.
In test operation, the function of the devices can be checked even at a low rotary speed.
oTurn the rotary switch (9) to the 1 or 2 position.
The test LED (2) lights up after a second.
oTurn the anemometer of the wind sensor.
The test LED flickers at the rotary speed of the anemometer.
Setting the wind speed threshold vale
oUsing the rotary switch (9), set the wind speed at which the blind/shutter is to move to the
protected end position (Figure 5). The setting is made in Beauforts Bft.
