After staircase time dimming to base brightness
Options: 100/99...1/0 % (OFF)
This parameter determines the base brightness which is continuously
controlled after the staircase lighting time .
Example
This option is used for example, for night time operation where the hall
lighting should remain switched on with a minimum brightness level value.
If someone enters the hall the light is switched on to a defined brightness
via a presence detector for the staircase light time.
Time for dimming down in s [0...65,535]
Options: 0...60...65,535
The parameter defines the speed used for dimming down at the end of
the staircase lighting time.
The dimming time relates to the minimum dimming value or the basis
brightness, depending on the value that is reached first. Using this logic
the light is always dimmed for the entire prewarn time, in order to provide
a sufficiently long warning before the staircase light is switched off.
Extending staircase lighting by
multiple operation ("pumping up")
Options: no (not retriggerable)
yes (retriggerable)
up to max. 2x staircase lighting time
up to max. 3x staircase lighting time
up to max. 4x staircase lighting time
up to max. 5x staircase lighting time
If a further ON telegram is received during the staircase lighting time,
the remaining staircase lighting time can be extended by a further period.
This is possible until the maximum time has been achieved. The maximum
staircase lighting time can be programmed and it can be set to 1, 2, 3, 4 or
5-fold time of the staircase lighting time. If a portion of the "pumped up" time
has already elapsed, it can again be pumped up to the maximum value.
The parameterised maximum staircase lighting time may not however be
exceeded. The warning time is not modified by the pumping up action.
•
no (not retriggerable): The receipt of a switch on telegram during the
running staircase lighting time is ignored. The staircase lighting time
continues without modification to completion. If an ON telegram is
received during the dimming time, the staircase light time is retriggered.
•
yes (retriggerable): The staircase light time is reset each time by an ON
telegram and starts to count again each time.
