Planning and application
This is a security feature to ensure that a calibration is not triggered
unintentionally during normal operation overwriting the set values.
The objects are ready to receive for an hour or until the calibration is
triggered (telegram with value 1).
The artificial lighting calibration is triggered by a telegram to the object
Calibration lighting. At the start of the calibration process the object
Calibration lighting is again automatically set to 0 by the Light Controller.
The Light Controller saves the current brightness value as a setpoint for light
control. At the same time the lighting is switched on with 100 % brightness
by the Light Controller and the lighting characteristic progresses to the value
0. In this way the brightness characteristic of the lighting is stored in the
Lighting Controller. The progression takes about one minute.
The lighting is switched off automatically by the Light Controller.
This concludes the artificial lighting calibration. The Light Controller switches
on the lighting and activates the light control. The end of artificial lighting
calibration is indicated when the value 0 from the object Calibration lighting
is sent on the bus. The T flag must be set for this purpose.
