You can also implement both functions (off delay timer and pulse relay) in a single unit. What is more,
you can incorporate extra functions without making any alterations to the wiring. In our example
program, we have combined the advantages of both the current impulse relay and the automatic
stairway lighting timer as follows:
•
Actuate the pushbutton
expiration of a predefined time.
•
Hold the pushbutton down
•
Press the pushbutton once more
7.1.2 The scheme of xLogic
The wiring of a lighting system with xLogic is the same as standard corridor or stairway lighting systems.
Only the automatic lighting timer/pulse relay is replaced.
xLogic lets you quickly and easily combine all those functions in a single dual-function switch SFB,
without additional wiring and expenditure.

When the input "I1" has a pulse, the output "Q1"will be on or off.
