14 KNX-BSA12L • KNX-BSA12H SATEL
Automatic after programming and restart –the blind/shutter travel time and slat
adjustment time (for slat blinds) will be recognized and saved by the module
automatically after being programmed and after each restart.
Automatic detection is enabled only by receiving the “Move up/down” telegram or
pressing the channel control button on the module enclosure.
You can only select the automatic detection for the blind/shutter whose motor is
equipped with the upper/lower limit switch. If the blind/shutter has an electronic motor
drive, the motor quiescent current must not be higher than 25 mA for KNX-BSA L and
60 mA for KNX-BSA H.
For the horizontal blinds, the slat adjustment time cannot be recognized automatically
by the module. Therefore, the “Time of slat adjustment” parameter is also displayed
after selecting automatic detection.
If, during the automatic detection, the module detects that the blind/shutter motor is
deenergized for longer than 30 seconds, the detection process will be stopped and the
module will report lack of synchronization between the blind/shutter and the module.
If, after restarting the process (e.g. using the buttons on the module panel), the module
reports lack of synchronization, check the blind/shutter motor supply circuit for
a possible fault.
Automatic detection will not start, if the channel is locked by the position forcing
function activated in it, or the weather alarm.
Automatic detection will only be carried out properly if the module correctly detects the
movement of blind/shutter in both directions (see “Service mode”).
Position tolerance –maximum distance from the target position at which the blind/shutter
can stop –see Fig. 10 (0 –100 [%]; default= 10). If, after stopping, the distance between
the blind/shutter and the target position is greater, the channel will report an error –
incorrect position of the blind/shutter (“Channel error alarm” and “Device error alarm”
communicationn object). The blind/shutter error does not block the channel, and
blind/shutter movement control is possible for the entire duration of the error. The error will
be automatically cleared when the blind/shutter reaches the end position in the opposite
direction to the one in which it was moving when the problem occurred. After the error is
removed, a telegram is sent to the KNX bus with information that the channel is working
properly. Entering the value “0” in the field disables checking the blind/shutter position
(an incorrect blind/shutter position will not cause any error).
The “Position tolerance” parameter is only available for automatic travel time detection.
Step: object type –selects the type of data for the “Stop/step up/down” communication
object. Sets the range within which the object values can be defined:
1-bit –the object can assume value 0 or 1 (0 = step up by the value defined in the “Step:
value” field; 1 = step down by the value defined in the “Step: value” field; if the
blinds/shutters / slats are moving 0 and 1 = Stop).
4-bit –the object can assume values from 0 to 100% and value “Stop” (0% = the upper
end position (fully open); 100% = the lower end position (fully closed); Stop = movement
stopped).
Step: value –percentage value by which the blind/shutter will be moved or blind slats
adjusted in response to 1-bit telegram from the “Stop/step up/down” communication object
or by a short press of the button for manual control of channel / blind/shutter (0 –100 [%],
default value = 10). The field is displayed in the tab, if the “1-bit” data type is selected for
the object.
