Art. No. DS 4092 TS
4.2.4.1.3 Push-button function Venetian blind
If the push-button is set to "Venetian blind", the ETS indicates the two 1-bit objects "Short-time
operation" and "Long-time operation". The long-time operation (long button-press) is used to
move a Venetian blind, rolling shutter or awning until the end position as required. The short-
time operation (brief press) is normally used to stop the long-time operation whereby any
blind/shutter position can be adjusted. Alternatively, the short-time operation can be used to
adjust the slat angle of a Venetian blind or the slit position of a rolling shutter. The operation
concept of the blind function defines how exact the time sequence of the telegrams is.
Operation concept for the Venetian blind function
For the control of Venetian blind, roller shutter, awning or similar drives, the device supports four
operation concepts for the push-button in which the telegrams are transmitted in different time
sequences. Therefore a wide variety of drive configurations can be operate with the push-
button.
The different operation concepts are described in detail in the following chapter.
Figure 4: Operation concept "short – long – short"
Operation concept "short - long – short":
In the operation concept "short – long – short", the push-button shows the following behaviour:
-
Immediately on pressing the button, the device transmits a short time telegram. Pressing
the button stops a running drive and starts time T1 ("time between short time and long time
command"). No other telegram will be transmitted, if the key is released within T1. This
short time serves the purpose of stopping a continuous movement.
The "time between short time and long time command" of the push-button should be
selected shorter than the short time operation of the actuator to prevent a jerky movement
of the blind.
-
If the button is kept depressed longer than T1, the device transmits a long time telegram
after the end of T1 for starting up the drive and time T2 ("slat adjusting time") is started.
-
If the button is released within the slat adjusting time, the device sends another 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 the button is kept depressed.
-
If the button is kept depressed longer than T2, the device transmits no further telegram.
The drive remains on until the end position is reached.
