"Fixed position" only: set the parameter "Fixed position of blind", "Fixed position of shutter/awning" or
"Fixed position of venting louver" to "as specified by parameter". Thereafter, set the parameter "Position
of blind (0…100%)", "Position of shutter/awning (0…100%)" or "Position of venting louver (0…100%)" to
the desired position.
At the beginning of shading, the output invariably approaches the parameterized position value.
"Fixed position" only: set the parameter "Fixed position of blind", "Fixed position of shutter/awning" or
"Fixed position of venting louver" to "no change of current position".
At the beginning of shading, the last adjusted height of the blind, of the shutter, of the awning or of the
venting louver will be maintained.
"Fixed position" and mode of operation = "blind" only. set the parameter "Fixed slat position (0…100%)"
to the desired position value.
At the beginning of shading, the output invariably moves the slats to the parameterized position after the
height of the blind has been adjusted.
Set the parameter "Reaction at the beginning of sunshine / shading" to "variable position".
At the beginning of shading, the shutter actuator recalls the variable position value for the output
concerned. The variable position of the height of the blind, of the shutter, awning or venting louver
position is preset via the separate communication object "Sunsh./shading ... position" (in the mode
"Blind" for the slats also via the separate object "Sunsh./shading slat position").
In the "Blind" mode of operation, the "variable position" setting can be selected separately for the height
of the blind and for the slat position. For this reason, the ETS adapts the parameter selection and
enlarges the setting options in this mode of operation.
The behaviour preset in this parameter will only be executed, if no function with a higher priority (e.g.
safety) is activated at the time of shading.
"Internal scene recall" setting: For this setting, the scene function of the output must be enabled in the
ETS. Otherwise, the positions approached at the beginning of sunshine/shading are undefined positions.
The scene position values stored in the actuator by a scene storage function will be approached as well.
A delay configured for scene recalls has no influence on the recall of the scene value by the sun
protection function.
"Variable position" setting: After an ETS programming operation or after switch-on of the supply voltage,
the objects "Sunsh./shading ... position" and "Sunsh./shading slat position" must receive position values
from the bus. Otherwise, the actuator makes no positioning attempts at the beginning of
sunshine/shading as it has no valid position data.
When the actuator is in operation, the position data can be updated at any time via the bus even if the
sun protection is active (e.g. by a weather station for the purpose of sun position tracking). The shutter
actuator will then immediately approach the newly received positions if the sun protection is active. If a
function with a higher priority is active, the actuator stores the newly received position values and
approaches them during a later shading operation.
The position data last received are not lost in a bus voltage failure (mains voltage on).
