3.2.5 Timer (tFCt)
The timer provides an output signal available for the binary functions. This signal can be used,
e.g. to realize a time-limited control or a time-dependent setpoint changeover.
The timer value is not saved during a mains failure. After the mains connection is restored, the
timer remains inactive.
