Defining the switch-off behaviour of the staircase function
In a staircase function, the reaction to an OFF-telegram to the "Staircase function start / stop" object can
also be parameterized. Without reception of an OFF-telegram, the output switches off after the pre-warning
time has elapsed. With a possible ON-delay and a pre-warning function, the staircase function has a switch-
off behaviour as shown in Fig. 16.

Fig. 16: switch-off behaviour of the staircase function
The parameter "Reaction to OFF-telegram" defines whether the staircase time (T
ON
) of the staircase
function can be stopped prematurely.
The staircase function must have been enabled on parameter page "Ax – Enabled functions (x = number of
output).
Set the parameter "Reaction to OFF-telegram" to "Switching off"
The output shuts off immediately when an OFF-telegram is received via the object "Staircase function
start / stop" during the ON-phase of the staircase time. If the staircase time is stopped prematurely by
such a telegram, there is no pre-warning, i.e. the pre-warning time is not started.
Set the parameter "Reaction to OFF-telegram" to "Ignore".
OFF-telegrams received during the ON-phase of the staircase time will be rejected. The staircase time
will be executed completely, if applicable with a pre-warning.
