Determining and configuring travelling times
For computing positions and also for executing long-time operation, the switching/shutter actuator needs
the exact travelling time of the connected blind, shutter, awning or louver. The travelling time for a shutter
output must be measured 'manually' and entered as a parameter into the ETS. It is important to determine
the travelling time accurately to permit positions to be approached with good precision. Therefore, it is
recommended to make several time measurements and to take the average of these values before entering
them into the corresponding parameter.
The travelling time corresponds to the duration of a travel movement from the completely open position
(upper end position / awning rolled up) to the completely closed position (lower end position / awning
completely unrolled) and not vice versa! Fig. 23 is a schematic showing the determination of the travelling
time as a function of the different types of movements.

Presetting the travelling time of blinds, shutters, awnings and louvers without automatic end
position detection
The measurement of the travelling time is described in detail in chapter "2.4 Commissioning".
The automatic end detection position must be deactivated.
Enter the exact travelling times determined in the course of the commissioning procedure into the
parameters "Blind travelling time" or "Shutter/awning travelling time" or "Venting louver travelling time" on
parameter page "A1 – Time settings" (x = number of output). The maximum travelling time is '59 minutes
59 seconds. The working principle does not allow longer travelling times.
The parameterized travelling time extension will moreover be taken into account by the actuator for all
upward travels or all travel movements into the open position as the drive motors are then generally no
so fast due to the weight of the curtains or to external physical influences (e.g. temperature, wind, etc.).
