In order to let users know the far going application field of xLogic, we present a set of
application example. Each instance includes the circuit program of its original solution and the
compare of solution in which xLogic has been applied.
You can find the following solution:
Dual-function switch
Automatic gate
Ventilation system
Industry door
Daylight lamps
Rain water pump
Note:
The application example of xLogic is available free of charge to our clients, but we can ’ t make
any promise, it is only to explain the general rule of using xLogic. It is possible that these
instances can be different from user ’ s specific application, so user should take all related
responsibility of running those instance systems, and we sincerely suggest user shall refer to
relevant nation standard and installation rules related to systems. Also, we have to point out
that error is unavoidable, and we reserve the according modification rights.

Requirements for stairway lighting systems
The basic requirements for a stairway lighting system are as follows:
• When someone is using the stairs, the stairway lights should be on.
• If no one is in the stairway, the lights should go out in order to save energy.

Up to now two methods were known to control such a lighting system:
• Pulse relay: When the lights are off, press any of the pushbuttons to switch on the lights.
When the lights are on, press any of the pushbuttons to switch off the lights again.
Disadvantage: People often forget to switch off the lights
• Automatic stairway light switch: Press any one of the pushbuttons to switch on the lights.
The lights switch off again automatically when a preset off delay time has expired.
Disadvantage: You can't keep the lights switched on over an extended period of time. The
permanent on switch, usually installed inside the stairway lighting timer unit, may be difficult or
impossible to access.
The wiring is the same for both systems.
