Application
The Multifunction Switch function block can be used for hallway or corridor lighting.
Basic Programming
A pulse on input Tr activates output Q for the specified time (parameter TH in seconds).
A switch-off warning (briefly switching the output on/off) notifies you prior to deactivating the output, to prevent you from being left in the dark by surprise.
Parameter TW specifies the time when the warning should occur in seconds before the final switch-off. The duration of the warning (duration of switching off) is specified with the parameter WT.
If the pulse on Tr is longer than the time set with parameter TT, output Q is permanently ON. A pulse on input O also sets output Q permanently ON.
