Description
Object 0
A channel light
Switching
In the <control type> "switching", the A light switch output sends an ON telegram on
detection of movement and insufficient brightness and an OFF telegram on completion
of the switch-off delay time or with sufficient brightness:
0 = Absence or sufficient brightness (OFF)
1 = Presence and insufficient brightness (ON)

Send value
Feedback value
Objects 1 - 3 are available if "constant light control" is selected as the <control
type>.
In the <control type> "constant light control", objects 0 - 3 are used for constant
light control. All four objects must be linked for a functioning constant light control.
A different response is produced depending on configuration:
Start control with value telegram:
A value telegram is sent via object 2 on detection of movement and insufficient
brightness. The actuator switches and dims up. An ON telegram is sent via object 1 on
reaching the set point value. The presence detector sends a request for the current
dimming value to the actuator via object 3. Control with 1-byte telegrams to object 2
starts from this dimming value.
Start control with ON telegram:
An On telegram is sent via object 0 on detection of movement and insufficient bright
-
ness. The actuator switches on and dims up to the configured value on the actuator.
The presence detector sends a request for the current dimming value to the actuator
via object 3. Control with 1-byte telegrams via object 2 starts from this dimming value.
The presence detector does not have any specific push button inputs but does respond
to push button commands sent to objects 0 to 2:
See information on push button operation on page 28 chapter 3.
Object 4
A brightness level
Receive value
Object available if "yes" has been selected at <set brightness level via bus>.
This enables the adapting of the brightness level during operation.
The brightness level value will not be accepted if the received value is outside the
value range (5..2000 lux) or the set point value does not match the current room
correction factor setting (see setting limit).
The value transfer will not be carried out if the received value is outside the value
range of the brightness level. Object 4 returns the stored value of the currently active
brightness level.
If an error occurs, object 35 provides the information for error diagnosis with a 1-byte
value. See „Diagnosis“ page 14
