Follow-up time of the inactive control
in s [0...65,535]
Options:
If constant lighting control is deactivated or interrupted by the user, e.g. by manual dimming, the current
dimmed-to brightness value is stored for the duration of the follow up time. The follow-up time commences
after the lighting group is switched off.
If the lighting is switched back on during the follow-up time using the communication object Switch
(manually or automatically by a presence detector), light control is not restarted. The lighting is switched
on with the brightness value stored beforehand.
If however, the lighting is switched on by the switching object after the follow-up time, the lighting control is
recommenced.
Should the lighting group be switched off during light control via the communication object Switch, a follow-
up time is not started.
This reaction is intended for the user who, after leaving the room and returning after a short period, wishes
to retain the lighting state set manually beforehand. This can be undertaken by manual switching or
automatically by a presence detector via the communication object Switch.
Note
The light controller can assume three operating states:
Light controller is not active: The light controller was deactivated via the communication object Fct
Activate controller/Status (telegram has been received with value 0). In this state, the lighting group
behaves like a "normal" DALI lighting group. ON telegrams on the communication object Switch do not
cause the light control to start. Only after a telegram with the value 1 has been received on the
communication object Fct Activate controller, is it possible to start the light controller. Whether the
additional function Light control is active is indicated by the communication object Status additional
functions, see
Light controller is in standby operation: The light controller is active but has however been ended,
e.g. by the OFF telegram to the communication object Switch. The light controller still remains active in
the background and starts again with control after an ON telegram to the communication object Switch
or Fct Activate controller/Status.
Light controller controlling: The DLR/S controls and adjusts the lighting so that the setpoint
brightness is set. The state of the light controller is indicated by the communication object Status
