Central function for outputs in switching mode
The actuator offers the possibility of linking selected individual or all output channels in switching mode with
a 1-bit central communication object. The behaviour in case of activating an output via the central function
is comparable to a central group address linked with all "Switching" objects.
The outputs assigned to the central function are activated in accordance with the central object value
received. The polarity of the central telegram can, if necessary, be inverted by means of a parameter.
The behaviour of the channels is identical with 'normal' activation via the "Switching" objects (same priority –
last switching command is executed – cf. Fig. 7). In this way, all 'secondary' functions such as timing or
supplementary functions or logic operations are included as well. The parameterized relay operation is also
evaluated for each output separately.

Enabling the central function
Enable the central function on parameter page "General" by setting the "Central function for outputs in
switching mode ?" parameter to "Yes".
When the function is activated, the "Centralized switching" communication object is visible.
Assigning outputs to the central function
Each switching output can be assigned independently to the central function.
The central function must have been enabled on parameter page "General". The assignment has otherwise
no effect on the switching output.
Set the "Assignment to central function" parameter on the "Ax–General" page (x = number of output) to
"Yes".
The corresponding output is now assigned to the central function. It can be switched on or off from a
central control station.
The switching state set by the central function is tracked in the feedback objects and also transmitted to
the bus, if they are actively transmitting. The switching state set by a central function is not tracked in the
"Switching" objects.
After a bus voltage return or after programming with the ETS, the central function is always inactive
(object value "0").
