Warning before end of staircase lighting
Options: no
via object
via quick switching OFF-ON
via object and switching OFF-ON
Before the staircase lighting time times-out, the user can be informed of the imminent switch off of
the lighting by a warning. If the warning time is not equal to 0, the staircase lighting time is extended
by the warning time. The warning time is not modified by the "pumping up" action.
•
no: No warning is given, the staircase light switches off immediately after the staircase lighting
time elapses.
There are two types of warning:
1. The communication object Staircase lighting warning is set to the value 1 at the commence-
ment of warning time and remains set until the warning time has elapsed. The communication
object can be used, for example, to switch a warning light.
2. Switching the output (briefly OFF and ON again).
Both possibilities can be set together or separately from one another. The time duration between
the OFF and ON process is about 1 second. If the warning time is not equal to 0, the staircase light-
ing time is extended by the warning time. If the staircase lighting is ended prematurely, e.g. by a
switching telegram, no warning is given.
Note
When dealing with the warning time, it is important to remember that the Energy Actuator draws
its switching energy exclusively from the bus. Furthermore, the Energy Actuator collects enough
energy before the first switching action to ensure that all outputs can safely go to the required
position should the bus voltage fail. Under these conditions, only a certain number of switching
actions are possible per minute, see
Warning time in sec. [0...65,535] add
to Staircase lighting duration
Options: 0...45...65,535
This parameter is visible if a warning is parameterized before the staircase lighting time
ends. The warning time must be entered in seconds. The staircase lighting time is extended
by the warning time. The warning is triggered at the start of the warning time.
The warning time is not modified by "pumping up".
Staircase lighting duration can be
changed via object
Options: no
yes
•
yes: A 2 byte Staircase lighting duration communication object is enabled. The staircase light-
ing time can be changed via the bus here. The value defines the staircase lighting time in se-
conds. The function Staircase lightning, which has already commenced, is completed. A
change of the staircase lighting time is used the next time it is accessed.
•
no: No modification of the staircase lighting time is possible via the bus.
