Art. No. DS 4092 TS
The rotary knob function "2-byte value transmitter" distinguishes three different functions...
-
Temperature value transmitter
In this function, the rotary knob transmits formatted 2-byte temperature values within a
range of "0...+40°C" according to the KNX data type 9.001. Such values are normally used
for basic setpoint temperatures for room temperature controllers.
Optionally, a value adjustment can be carried out by adjusting the rotary knob by a defined
rotation angle.
-
Brightness value transmitter
In this function, the rotary knob transmits formatted 2-byte temperature values within a
range of "0...1500 lux" according to the KNX data type 9.004. Such values are normally
used for brightness setpoint presettings for constant light regulation.
Optionally, a value adjustment can be carried out by adjusting the rotary knob by a defined
rotation angle.
-
Value transmitter (0...65535)
In this function, the device is able to transmit unformatted 2-byte values within a range
"0...65535" to the bus according to the KNX data type 7.001. Such values are normally
used for the presetting for counter limiting values.
Optionally, a value adjustment can be carried out by adjusting the rotary knob by a defined
rotation angle.
The rotary sensor differentiates between different operations (e.g. transmit value 1, afterwards
value 2) based upon the time that the rotary knob stands still after a completed operation. The
"Time for standstill after each movement" is configured in the ETS and should not be selected
too short in order to avoid unintended control operations - particularly during fast operations. If
the device detects additional operations immediately after a rotary movement (time not yet
elapsed), it evaluates the continuing movement of the rotary knob and executes further
reactions as described if necessary. The time for standstill detection is retriggered for each
rotary knob movement.
With the 2-byte value transmitter a distinction is made as to whether just a value recall takes
place and whether a value adjustment is also possible...
Function value adjustment disabled:
When operating the rotary knob, a 2-byte value telegram according to the ETS configuration is
already transmitted in this case after the first notch (minimum rotation angle) depending on the
direction of rotation. Different values can be preset for the clockwise or anticlockwise
movements of the rotary knob (figure 30). The values are always transmitted to the bus via the
same communication object.
i
If the direction of rotation changes without interruption during an operation, the rotary knob
does not transmit any further telegram. The device evaluates this operation as a wrong
operation.
i
The rotation angle (number of notches during a rotary movement) and the speed of rotation
have no significance for this function. During a new operation, a telegram is already
transmitted to the bus after the first notch (minimum rotation angle).
