»
Protection Para/P-Set Switch«
Via Input Function
(e.g. Digital Input)
Switch over not until the request is clear.
That means, if there is more or less than one request signal active, no switch
over will be executed.
Example::
DI3 is assigned onto Parameter set 1. DI3 is active „1“.
DI4 is assigned onto Parameter set 2. DI4 is inactive „0“.
Now the device should switch from parameter set 1 to parameter set 2. Therefore
at first DI3 has to become inactive “0”. Than DI4 has to be active “1”.
If DI4 becomes again inactive „0“, parameter set 2 will remain active “1” as long
as there is no clear request (e.g. DI3 becomes active “1”, all the other
assignments are inactive “0”)
Via Scada Switch over if there is a clear SCADA request.
Otherwise no switch over will be executed.
The description of the parameters can be found within chapter System
Parameters.
