Artificial light calibration
1)
(using lighting group 1 as an example)
Version
By
Effect
1.
Checking of the light sensor(s)
that is/are relevant for light
control.
Read out communication object Status
Sensors (no. 9).
The corresponding bit(s) for the
relevant light sensor must have the
value 1.
1a.
Check the light sensor position.
Sensor value is not subject to
interference.
2.
Deactivate light control.
Send the value 0 to communication
object Fct Activate controller/Status
(no. 31).
Light control is deactivated.
3.
Slaves must be active and
integrated in the lighting.
Write the value 1 to corresponding
communication objects Function Slave.
The entire lighting which is effective
in the control must be active during
calibration.
4.
Dim room lighting.
Blind or time of day.
Brightness in the detection range of
the light sensor(s) less than 20 lx
2)
5.
Set the artificial lighting so that
the setpoint brightness is set to
the reference point.
The light sensor should be
positioned above the reference
surface.
Dimming via communication object
Relative dimming (no. 34) or set
brightness value via communication
object Brightness value (no. 32).
Setpoint is set, e.g. 500 lx.
The sensor of the lux meter should
be positioned vertically below the
light sensor.
6.
Switch calibration
communication object to ready to
receive.
Send a telegram to communication
object Enable controller calibration
(no. 27) with the number of the
controller group.
Communication objects Calibration
artificial light and Calibration daylight
are ready to receive for 1 hour or
until calibration has been completed.
7.
Initiate artificial lighting
calibration.
Send a telegram with the value 1 to the
communication object Calibration

Light controller commences
calibration of artificial light. Jump to
100 % brightness. Dimming to 0.
The calibration is completed after
about 1 minute.
8.
Artificial lighting calibration end.
Automatic through DALI Light
Controller.
At the end, the lighting control is
active and controlled.
1)
Before the artificial light calibration, ensure that the lighting equipment offers a constantly reproducible dimming
performance during dimming. For this purpose, the burn-in time (
Effect of ageing on lighting equipment
, page 164) of the
lighting equipment must be considered and already completed. Consider also that a fluorescent lamp only develops its full
lighting intensity after a few seconds.
2)
Interference in the artificial light calibration caused by daylight has the effect that the DLR/S assumes that the illumination
can produce a larger brightness level than is actually the case. The DLR/S will set a lower level of brightness in light
control operation.
