Switching the light on/off permanently, or switch-
ing off after a cycle time has elapsed
With a brief press of a push-button, the switch actuator
switches the light on or off permanently. With a long
press of a push-button, the light switches on, and after
a parameterised cycle time (e.g. 6 minutes), it switches
back off again. Due to the cycle time in the push-button
which can be parameterised, the switch actuator re-
quires no staircase lighting function for this function.
Electronic protection against theft
This example will show you how to program electronic
theft protection for the push-button. It is activated by a
brief push-button action and then transmits cyclically.
As soon as the push-button is forcibly separated from
the bus, this can be reported or an alarm can be trig-
gered.
Effect lighting
This example shows you how to program effect lighting,
for example for a display window. A long push-button
action switches between two different lighting scenes.
A short push-button action stops the toggling and trans-
mits a scene which switches off everything. The scene
module of the push-button is used to retrieve the scene.
Communication objects
You can select the following communication objects:
Number of objects = 2 (object A/B)
Object A/B = 1 bit
Object A: Action on release before the long operating time has
elapsed = toggles
Object B: Action on achieving the long operating interval = sends 1
and after a cycle time 0.
Action on release after achieving the long operating time
= no change.
Cycle time = e.g. 6 minutes.
Connect object A and object B with the switch object of the switch ac-
tuator.
Number of objects = 1 (object A)
Object A = 1 bit
Object A: Action on release before the long operating time has
elapsed = Sends 1 immediately and then cyclically.
Action on achieving the long operating time = No change.
Action on release after achieving the long operating time
= No change.
Cycle time = e.g. 10 minutes.
Connect object A with an object that listens cyclically for telegrams
(e.g. a safety object). The monitoring time set on the safety object
must be longer than the cycle time of the push-button. If the safety
object receives no telegrams from the push-button during this time,
a reaction which can be parameterised is activated (e.g. channel is
switched on).

Object A: Direct action on operation = None (stops cyclical send-

Action on release after achieving the long operating time

Object B: Direct action on operation = None (stops cyclical send-
ing).
Action on release before the long operating time has
elapsed = None (stops cyclical sending).
Action on achieving the long operating time = None
