4.2.4.2.5 "Venetian blind" function
If the function of the input is configured to "Venetian blind", various parameters for the Venetian
blind function and the "Short time operation" and "Long-time operation" objects are visible. The
"operation concept" parameter predefines the telegram sequence for short and long-time
telegrams that are transmitted with or during button actuation.
For controlling the Venetian blind, shutter or awning operations the push button interface is
supported by two operation concepts, in which the telegrams are transmitted with a different
time sequence. Therefore a wide variety of drive configurations can be operate. The different
operation concepts are described in detail in the following chapters.
Operation concept "short – long – short"
In the operation concept "short – long – short", the input shows the following behaviour...
-
Immediately after a rising edge 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 and long time command" 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 a falling edge is detected within the slat adjustment time, the device 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 travelling time of the drive, a
pushbutton function is possible as well. In this case, the driver only remains on while the
button is kept depressed at the input. 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.
Figure 8: Operation concept "short – long – short"
Operation concept "long – short":
In the operation concept "long – short", the input shows the following behaviour...
-
Immediately after a rising edge the device transmits a long time telegram. The drive begins
to move and time T1 ("slat adjusting time") is started.
-
If a falling edge is detected within the slat adjustment time, the device transmits a 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 travelling time of
the drive, a pushbutton function is possible as well. In this case, the driver only remains on
while the button is kept depressed at the input.
-
If the button is kept depressed longer than T1, the device transmits no further telegram.
The drive remains on until the end position is reached.
