Planning and application
As an example short operating instructions for output A are listed for
automatic daylight calibration:
Implementation
Daylight calibration
0. Calibration lighting
1. Deactivate lighting
control
2. Switch off artificial
lighting.
3. Set the setpoint
brightness, e.g. 500 lx
with daylight.
4. Switch calibration
object to ready to
receive.
5. Initiate daylight
calibration.
6. End of daylight
calibration.
1)
Before the daylight calibration ensure that the luminaries feature a constantly reproducible
dimming performance during dimming. For this purpose the burn-in time (see section 4.7.4)
of the luminaries must be considered and already completed. Consider also that some
fluorescent lamps only develop their full lighting intensity a few seconds after being switched
on.

table
Send 0 to object activate
control (No. 24).
Send 0 to object Switch
control (No. 10).
The same setpoint can be
set using blinds or time of
day as with artificial lighting
calibration.
Note: In order to prevent
with a high level of certainty
that the setpoint is not
undershot in the controlled
state, a brightness about 10
% above the brightness
value of artificial brightness
calibration is set.
Send a telegram with the
value 1 to object Enable
calibration (No. 25).
Send a telegram with the
value 1 to object Calibration
daylight (No. 27).
Automatic via LR/S.
Effect
Lighting characteristic
stored in the Light
Controller.
Control is deactivated.
Artificial lighting switched
off.
Setpoint is set, e.g. 500 lx.
Optional manual
calibration possible.
Object Calibration lighting
and Calibration daylight
are ready to receive for 1
hour.
Control commences
calibration of daylight.
Calibration has ended after
about 10 seconds.
At the start of the daylight
calibration the object
Enable calibration (No. 25)
is again set to 0.
Control active and
controlling. Value of the
object Calibration daylight
(No. 27) is reset to 0.
