Allow switching ON via brightness value
Options:
This parameter defines the switch on performance of the lighting group with a received brightness value.
yes: Switch on with a brightness value is permitted.
no: Switch on with a brightness value is not permitted. The lighting group must be switched on in order
to execute the brightness value telegram.
Allow switching OFF via brightness value
Options:
This parameter defines the switch off performance with a received brightness value.
yes: Switch off with a brightness value is permitted.
no: Switch off with a brightness value is not permitted. The DALI output must be implemented with an
OFF telegram via the communication objects Switch or Switch/status.
Dim period to reach turn on or off
brightness (Fct. "Switch") in s
Options:
A soft start or soft stop can be set with this parameter. For this purpose, the time duration in which the
DGN/S dims the lighting group from 0 % brightness to the switch on value with an ON telegram is defined.
The same speed also applies for an OFF telegram. The dim period is only relevant for ON/OFF telegrams
(1 Bit).
The time received via the communication object Flexible time has an effect on the ON/OFF switch-
ing performance. The flexible dimming time has a value between 0...65,535 seconds.

Dimming time changeable via
obj. "Flexible time" 2 Byte
Options: yes
no
communication object no.
yes: The time received via the central communication object Flexible time (DALI output) is used
as a dimming time for the switch on/off value.
no: The dimming time for the switching on and off value cannot be changed via KNX.
Note
The switch off time is also considered when the lighting group is at the lower dimming threshold
and an OFF telegram is received. In this case, the lighting group switches off at the lower dim-
ming value limit only after the programmed dimming time for switch ON/OFF. This ensures that
all lighting groups switch off simultaneously.
