Art.-No.: 2095 LUX
After that a telegram must be sent on communication object 8 "Calibrate setpoint" to the
brightness controller. Only after that is it possible - if set previously - to set the setpoint back to
the desired value.
A successful calibration can be performed by reading communication object 9 "Brightness,
measured value". In case of unchanged brightness conditions after the last calibration the
measured brightness value must correspond to the calibration value.
Response to a device reset
In case of bus voltage failure the current status of the objects "Presence" and "Automatic mode"
and the last switching command or dimming value sent by the controller are saved in the non-
volatile memory. In case of bus voltage return the brightness controller adopts the status of the
saved objects and then enters the operating status determined by the two status values and the
parameter "Response to bus voltage return".
If this causes the automatic mode to be activated, the device transmits a switching or dimming
value telegram only if the switching state or dimming value calculated by the controller based on
the current light conditions differs from the one last transmitted.
