The safety travel time required by an output to move the drive into the end positions is determined by the
"Travel time" parameter on parameter page "Ax - Time settings". Like the long-time operation, a safety
travel is derived from the travel time. Downward travel: travel time + 20 %; Upward travel: travel time +
20 % + parameterized or taught-in travel time extension. safety travels are not retriggerable.
Slats of blinds are not repositioned at the end of safety travels into end positions.
Presetting the behaviour at the end of all safety alarms
The switching/shutter actuator ends the safety interlock of an output only after all safety alarms assigned to
the output have become inactive. Thereafter, the output concerned shows the parameterized "Behaviour at
the end of safety". This behaviour is parameterized in common for all alarms on parameter page "Ax –
safety" (x = number of output).
Depending on the selected mode of operation, the ETS adapts the designations of the parameter settings
("raising"
↔
"opening the louver" / "lowering"
↔
"closing the louver").
The safety functions must be globally enabled on the "Shutter outputs safety" parameter page.
The safety function for an output must be enabled on parameter page "Ax – Enabled functions (x = number
of output). Only then are the channel-related parameters for the safety function visible.
Set the parameter "Behaviour at the end of safety" to "no reaction"
At the end of all safety alarms, the output is released and the relay of the output shows no reaction. Any
travel movements still in progress at this instant will still be finished.
Set the parameter "Behaviour at the end of safety" to "raising" or "opening the louver".
The actuator releases the output at the end of all safety alarms and raises the curtain or opens the
venting louver.
Set the parameter "Behaviour at the end of safety" to "lowering" or "closing the louver".
The actuator releases the output at the end of all safety alarms and lowers or closes the venting louver.
Set the parameter "Behaviour at the end of safety" to "stop"
At the end of all safety alarms, the output is released and the actuator switches the relays of the output to
"stop". A travel movement in progress, if any, will be interrupted.
Set the parameter "Behaviour at the end of safety" to "tracking the position".
At the end of all safety alarms, the output will be set to the state last adjusted statically before the safety
function or to the state tracked and internally stored during the safety function. The position objects, the
long-time object and the scene function are tracked.
Parameter setting "Position tracking": The switching/shutter actuator can track absolute positions after
safety release (position telegram, scene value) only if the position data are known and if the positions
have been predefined. In all other cases, no reaction takes place on release of safety.
Position data can be tracked, if the output was in a defined position before the safety function or if a new
position telegram was received via the position objects during the safety interlock. In the latter case, a
reference travel will be executed when the safety function is enabled, if the position before or during the
safety interlock was unknown.
Known slat positions will also be tracked as described. This is also the case, when the height of the blind
is unknown.
Long-time travel movements (travels without position preset) will, however, always be tracked.
The preset "Behaviour at the end of safety" will only be executed, if the output passes over to direct
operation at the end of all safety alarms. If a sun protection function is activated (independent of the
preset priority with respect to direct operation), it will be also executed.
