actuator. The synchronization run has to be initiated again
as described above.
If a message “block motion” is received during the syn-
chronization run, then the synchronization run is aborted.
It can only be initiated again, when the motion blockage
is ended by a respective telegram.
All other telegrams received after a download before and
during a synchronization run are ignored.
If the solar protection shall move to the upper or lower
end position in normal operation, the travel time is calcu-
lated such that the drive reaches the respective end posi-
tion. The actuator stops the motion when the end position
is detected. A possible short opening movement of the
slats or a short lifting of a roller shade is immediately exe-
cuted after stopping the motion.
When a change of the solar protection travel times of
more than +-5% is detected during normal operation
based on the end position detection, then the travel time
configuration settings are corrected and saved accord-
ingly.
Because the electromechanical end position switch does
not close at the same time the solar protection leaves the
end position, it is necessary to block evaluation of the end
position for this period. This “blocking period” can be con-
figured via a parameter. Typical values for the blocking pe-
riod” are 0.5 to 1.0 seconds.
Behavior at bus voltage failure / recovery
In the event of bus voltage failure the current positions of
solar protection and slats as well as the travel time config-
uration is permanently saved to be restored on bus volt-
age recovery. Object values are not saved.
Status objects are not read after a bus reset.
Actions configured for execution on bus voltage failure
are only executed, if no alarm or blockage is active.
Actions configured for execution on bus voltage recovery
are only executed and possible new positions transmitted,
if no alarm or blockage was active before bus voltage fail-
ure. The information (not the object values) about alarm
and blockage before bus voltage failure is only saved for
the initialization phase after bus voltage recovery. It is re-
set (no alarm active, no blockage active) after initializa-
tion. Consequently, if e.g. before bus voltage failure a
blockage was active, the solar protection cannot be
moved into a configured position on bus voltage failure or
on bus voltage recovery. If after bus voltage recovery fur-
ther messages to move the solar protection are received,
then these are executed because the blockage present be-
fore bus voltage failure is not saved. Thus an explicit
release of a blockage after bus voltage recovery is not re-
quired.
If alarm surveillance periods are configured, then these
are restarted on bus voltage recovery.
The synchronization is retained on bus voltage failure and
recovery. Yet, the actuator assumes that any function con-
figured for bus voltage failure has been fully executed. If
this is not the case, the calculated position may deviate
from the actual position until the solar protection has
been moved to an end position.
Behavior on unloading the application program
When the application program is unloaded with ETS the
device does not function.
Resetting the device to ex-factory settings
When the programming button is pressed for more than
20 seconds the device is reset to the ex-factory settings.
All configuration settings are lost.
The device is configured and commissioned with the ETS
(Engineering Tool Software) version ETS3 v3.0f or later.
Application Program
The RL 521/23 Shutter / blind actuator needs the appli-
cation program "07 B0 A1 Shutter Actuator 982B01“.
