Art. No. DS 4092 TS
4.2.4.6 Status-LED (only with application program of version 1.2)
The rotary sensor has two red Status LEDs, which can be configured independently of one
another. The Status LEDs can execute various display functions, provided that their use is
generally enabled on the parameter page "Push-button (PB) / Rotary knob (RK)". The left Status
LED is assigned to the push-button and the right LED to the rotary knob. Consequently, the
LEDs display operations of a button-press display or telegram acknowledgment according to
this assignment.
The use of both Status LEDs is optional. If the visual display functions are required, then special
design covers with light guides must be used (see page 7-8).
i
The LED display functions can only be configured and used with Version 1.2 of the
application program! If Version 1.1 of the application program is used, the Status LEDs are
only activated when alarm signalling is active.
i
The Status LEDs always indicate that an application program has been unloaded by
flashing slowly.
The following functions can be configured separately for each Status LED...
-
always OFF,
-
always ON (orientation light),
-
Status indicator (via LED object),
-
Inverted status indicator (via LED object),
-
Button-press display.
The following function can additionally be configured specially for the left Status LED (push-
button)...
-
Telegram acknowledgment.
Function "Always OFF" or "Always ON"
With this parameterisation, a status LED remains permanently switched on or off. Permanently
switched-on Status LEDs can be used, for example, for orientation lighting.
Special case: In the "Always OFF" setting, the Status LEDs display adjustments of the
transmission values in the "Value transmitter" button or rotary knob function, provided that this
function has been enabled in the ETS and is executed by the operator. The LEDs then light up
briefly when a new value adjustment telegram is transmitted. In the case of the left Status LED
for the push-button, in the "Always ON" setting, the continuous light is interrupted for the length
of the value adjustment. The LED lights up briefly for each adjustment value transmitted to the
bus. By contrast, when in "Always ON", the right Status LED of the rotary knob remains
switched-on without interruption, even if a value is adjusted.
Function "Button-press display"
If a Status LED is working as a button-press display, it lights up when the rotary knob or the
push-button is actuated. In the case of the rotary knob, the right-hand LED always then lights up
at the start of an operation. In the case of the push-button, the Status LED lights up on pressing
and releasing (exception: Scene extension with memory function: Here, after short operations,
the LED only lights up on release).
In addition, the LED signals to the push-button when a storage telegram is being transmitted in
the function "Scene extension". In addition, in the "Value transmitter" function, the LEDs for the
push-button and rotary knob display the transmission of a value adjustment telegram.
The light period of the button-press display can generally be set in the ETS using the "Light
period of the Status LED for button-press display" parameter. In contrast to this, the signal
duration of the display for a scene storage telegram (approx. 3 seconds) and the value
adjustment (250 milliseconds) is permanently defined.
