Blind actuator 1-gang flush-mounted Order-No. 2165 00 - Gira

Software "Venetian blind, input 20BD11"
Functional description
Figure 12: Type 1 - Slatted Venetian blinds with oblique slat position in both travel directions
There are also single-motor Venetian blind systems without a working position the slats of which
are horizontal during an upward travel and oblique during a downward travel. Such Venetian
blind types can also be connected to the device in which case a completely open slat position
corresponds to the slats in horizontal position .

Presetting the slat moving time
The measurement of the slat moving time is described in detail in chapter "Commissioning".
o Set the parameter "Slat moving time" on parameter page "O1 - Times" exactly to the value
determined in the course of the commissioning procedure.
i The slat moving time must be shorter than the preset or learnt blind travelling time.
i The configured or measured movement time extension will also be taken into account
when slats are moved into the completely open position (upward movement).
Determining and configuring the movement time extension and the switchover time
When moving upwards, Venetian blinds, roller shutters or awnings have a tendency of moving
more slowly due to their own weight or to external physical influences (e.g. temperature, wind,
etc.). The same applies to venting louvers where opening may take longer than closing.
For this reason, the device takes the configured travelling time extension into account when
moving upwards or when opening louvers. The extension is computed as a percentage of the
difference of the movement times in both directions.
The movement time extension should be determined separately during commissioning and
entered into the ETS configuration.
The measurement of the movement time extension is described in detail in chapter
"Commissioning".
Example for determining the movement time extension:
