A newly received object value (sun / beginning of shading or sun / end of shading ) can optionally be
evaluated with a time delay. This feature permits suppressing brief increases of brightness caused, for
instance, by light clouds or by a thunderstorm.
An update (from activated to activated) of the "Sunshine / shading facade" object causes the sun protection
to be reactivated, if it had been influenced and possibly been re-enabled beforehand by a direct operation in
acc. with the preset priority.
The reaction of a specific output at the beginning of shading can be preset in the ETS. This setting permits
approaching fixed parameterized positions or positions preset via the bus and thus variable. Variable
positions for sun protection purposes can be preset, for instance, by means of touch sensors or
visualizations. In addition, it is possible in case of a defined sun protection positioning movement to have a
reference travel executed by forced control. This ensures that identical curtain positions are approached
synchronously by different outputs in case of a sun protection positioning movement.
The reaction at the end of a shading task can be preset as well. In this situation, the curtain can pass into
an end position, be stopped or shown no special reaction. Tracking of positions is possible as well.
By means of a priority setting in the ETS parameters it can be specified whether the sun protection function
can be influenced by operation or whether the corresponding output is locked by a telegram "Sunshine /
shading facade " in the sun protection position. Basically, the "Manual control", "Forced position" and
"Safety" functions have a higher priority so that these functions can override, but not terminate a sun
protection. Thus, the sun protection function is re-executed at the end of a function with a higher priority, if
the object "Sunshine / shading facade" continues to signal the presence of sunshine.
After an ETS programming operation, the sun protection function is always deactivated. An activated sun
protection (independent of the selected priority with respect to direct operation) remains active even after
a bus voltage failure as long as the mains voltage supply is still on. The sun protection reaction last
executed will therefore be executed again at the end of a temporary or permanent manual control (if
enabled in case of bus failure), even if there is no bus voltage.
