This logic group is used to enable an even use (duty cycle) of the lamps of two lamp circuits.

Via the "Lighting" input, the user can only switch the lighting on/off.

The logic group itself defines which lamp circuit is switched. Via the "WEEK" output of the time transmitter element, a telegram is triggered weekly that activates or deactivates the two gate elements alternately.

Thus, the ON telegrams from the "Lighting" input are always only forwarded to the output whose gate element is activated.
The OFF telegram, on the other hand, is always forwarded to both lighting circuits via a separate path to ensure that both lighting circuits can be switched off at any time.

In addition, the user can manually change the lighting circuits via the "man. Change" input to change the lighting circuits manually.

The element "... initialise." (fixed value) has the task of setting the GATE inputs of the gate elements to a defined state when the logic group is activated.
