The set time (delay or timeout) marks a switch on or off sequence that may consist of one or more objects.
The times apply for the entire sequence and take effect, when a switch on or step up command or a switch
off or ramp down command is demanded.
Switch on occurs in parallel per sequence. A check of the switch on state occurs only in the switch on type
timeout. The next sequence is only started after either all monitored objects report a switched on state or
the timeout period expires. Operating state monitoring of the objects for monitoring, as depicted in the
following figure, only become active after the step-up process for a sequence is completed.

Sequence 2 has no active switch-on command
in stage X, and is therefore skipped.
Objects 6 and 7 are switched on in parallel.
The state monitoring mechanism waits
max. 2 minutes for objects 6 and 7 to
transmit an On signal.
Object 8 is inactive in stage X.
Sequence 1
Sequence 2
Sequence 3
Objects 1, 2 and 3 are switched on in parallel.
As soon as 1 and 3 transmit an On signal
or the 30 sec. timeout expires,
the transition to the next sequence starts.
