Presetting the fabric-stretching function
The fabric-stretching function can be parameterized independently for each shutter or awning output on
parameter page "Ax – Fabric-stretching" (x = number of output). The travel time required for fabric
stretching by means of a movement in opposite direction can be parameterized.
The fabric-stretching function must be activated.
Select the desired value for the "Time for fabric-stretching" parameter.
After the end of a downward travel the curtain stops and – after elapsing of the changeover delay –
moves backwards in opposite direction for a period corresponding to the parameterized fabric-stretching
time.
The time for fabric stretching must be selected shorter than the parameterized or measured travel time of
the shutter or awning. Otherwise, risk of malfunction.
Fabric stretching will only be effected if the downward movement lasts longer than the parameterized
fabric-stretching time.

Delivery state
In the state as delivered, the actuator is passive, i.e. no telegrams are transmitted to the bus. The outputs
can, however, be operated by manual control on the device, if the mains voltage is on. In the manual control
mode, no feedback telegrams are sent to the bus. All other functions of the actuator are deactivated.
The device can be programmed and put into operation with the ETS. The physical address is preset to
15.15.255.
Moreover the device has been configured at the factory with the following characteristics...
–
Channel definition: all outputs configured for shutter operation
–
Travel time (continuous run): 1 minute
–
Travel time extension 2 %
–
Break during travel direction changeover 1 s
–
Response to bus voltage failure: no reaction
–
Behaviour on return of bus or mains voltage: stop
