The following can be selected:
OR function
AND function

The activation of the logic function means that the switch object of the respective channel
(output) interacts with the logic object of the associated channel (output).
Time switches (staircase lighting timer) or timing functions (ON, OFF and ON/OFF delays)
can also be used.

2.1.3 OR Function with Timing or Time Switch Function
It is a good idea to use the available OR function in combination with timing functions or
time switch functions.
It should be noted that the specified delay period only influences the switch object of the
respective output. It is therefore possible to switch circuits for specific applications directly
(via logic objects) and with a time delay (via switch objects).

Figure 2: Switch actuator with OR function
The conventional staircase lighting function is possible here as a time switch application
which is activated via the switch object. The group addresses in the logic object enable
the maintained lighting function to be implemented as there is no active timing function in
this case.
