Functional description
Each Seven-day time switch has three cams you can use to
configure a time hysteresis. You specify the on- and
off-times at the Cam parameters. The Seven-day time switch
sets the output at a certain on-time, if this is not already set.
The Seven-day time switch resets the output at a certain
off-time, if it is not switched off already. You will cause a con-
flict if the on- and off-times you set for the Seven-day time
switch are identical, though set on different cams. In this
case, cam3 takes priority over cam2, whereas cam2 takes
priority over cam1.
The switching state of the Seven-day time switch is deter-
mined by the status of all three cams.
