Interlockings are carried out with the status changes of the switching device. Remove acquisition blocking
again manually. Otherwise, position changes of the switching device are not detected and interlockings are
ineffective.
If the acquisition blocking and the manually updated position are set using the operation panel of the device
or the system interface IEC 61850, these are retained until the acquisition blocking is manually deactivated.
When you initially start the device, the acquisition blocking is deactivated.
Except for a restart, the acquisition blocking and the manually updated position are retained.
If the acquisition blocking is activated via the input signal >Acquisition blocking, it is retained as long as
the binary input is active.
To set the acquisition blocking of a switching device, the following sources are possible:
•
Operation panel of the device
•
System interface IEC 61850
•
Input signal >Acquisition blocking
All sources undergo OR operations, that is, the acquisition blocking remains set until all the sources are deacti-
vated.
After deactivation of the acquisition blocking, the actual position of the switching device is adopted and
displayed in the operation panel of the device.

When the acquisition blocking is activated or the switching device updated manually while the entire
device or the switching device is in test mode, these states are not saved. The acquisition blocking and the
manual updating are not retained after a restart.
The acquisition blocking and the manual update for the circuit breaker, the disconnector, and the tap changer
are reset by way of the >Reset AcqBlk&Subst binary input. Setting acquisition blocking and manual
update is blocked with the input activated.
