Art. No. DS 4092 TS
4.2.4.4.3 Extension function Venetian blind
For each input, whose function is set to "Venetian blind", the ETS indicates the two 1-bit objects
"Short time operation" and "Long time operation".
For the control of Venetian blind, roller shutter, awning or similar drives, the device supports two
operation concepts for the Venetian blind function in which the telegrams are transmitted in
different time sequences. The device can therefore be used to operate a wide variety of drive
configurations. In the ETS, the operating concept of an input is defined using the parameter of
the same name on the parameter page "Ix - General" (x = 1, 2, 3). The following settings are
possible...

Operation concept of the Venetian blind function
Operation concept "short - long – short":
In the operation concept "short – long – short", the input shows the following behaviour:
-
Immediately after a rising edge (closed pushbutton or switch) the input transmits a short
time telegram onto the bus. Pressing the button stops a running drive and starts time T1
("time between short time and long time operation"). If the a falling edge is detected within
T1 (closed pushbutton or switch), no further telegram will be transmitted. This short time
serves the purpose of stopping a continuous movement.
The "Time between short time and long time command" in the input parameters should be
selected shorter than the short time operation of the actuator to prevent a jerky movement
of the shutter.
-
If the button is kept depressed longer than T1, the input transmits a long time telegram after
the end of T1 for starting up the drive and time T2 ("slat adjusting time") is started.
-
If a falling edge is detected within the slat adjustment time, the input transmits an additional
short time telegram. This function is used for adjusting the slats of a blind. The function
permits stopping the slats in any position during their rotation.
The "slat adjusting time" should be chosen as required by the drive for a complete rotation
of the slats. If the "slat adjusting time" is selected longer than the complete running time of
the drive, a push button function is possible as well. This means that the drive is active only
when a button connected to the input is kept depressed.
-
If the button is kept depressed longer than T2, the input transmits no further telegram. The
drive remains on until the end position is reached.
