Presetting scene positions
Moreover, the position value (blind, shutter, awning, venting louver position) to be set for the output in case
of a scene recall must be specified as well. In the "Blind" mode, the height of the blind and the slat position
can be preset.
The scene function must be enabled on parameter page "Ax – Enabled functions (x = number of output).
Set the parameter "Position ... for scene y" (y = number of the scene (1…8)) on parameter page "Ax –
scenes" for each scene to the desired position (0 %...100 %).
In case of a scene recall, the output is set to the parameterized position.
The parameterized position values are adopted in the actuator during programming with the ETS only if
the parameter "Overwrite values stored in the device during an ETS download ?" is set to "yes".
Before approaching the required scene position, the switching/shutter actuator performs a reference
travel, if the current position data are unknown (e.g. after an ETS programming operation or after switch-
on of the supply voltage).
Presetting the storage behaviour for the scene function
The current position value of a blind, shutter, awning, venting louver and also of a slat can be stored
internally via the extension object on reception of a scene storage telegram. The position value can be
influenced before storage by all functions of the output (e.g. short-time and long-time operation, central or
scene recall telegram, safety and sun protection function and manual control).
The scene function must be enabled on parameter page "Ax – Enabled functions (x = number of output).
Set the parameter "Storage function for scene y" (y = number of the scene (1…8)) on parameter page
"Ax – scenes" for each scene to "yes".
The storage function is activated for the scene in question. On reception of a storage telegram via the
"Scene extension" object, the current position value will be internally stored.
Set the parameter "Storage function for scene y" (y = number of the scene (1…8)) on parameter page
"Ax – scenes" for each scene to "no".
The storage function is deactivated for the scene in question. A storage telegram received via the "scene
extension" object will be rejected.
The following rules apply for the position data to be stored:
The current curtain, slat and louver positions are stored. With blinds, the height to be stored is always
referred to a slat position of 100 %. Positions temporarily approached will be stored also for those outputs
that are involved in a travel movement at the time of data storage.
On account of the fact that position data are stored as integer percentage values (0...100), a minor
deviation from the positions adjusted later during a scene recall cannot be avoided.
The data are stored only if the mains voltage was available beforehand during at least 20 seconds after
the last reset (storage capacitors sufficiently charged for storage purposes). The data will not be stored, if
the position data are unknown.
