Acquisition Blocking and Manual Updating
During commissioning, maintenance, or testing, a brief interruption of the connection between the logical
signals and binary inputs may be useful. It allows you to manually update the status of a switching device that
is not providing feedback correctly. Before this can take place, you must first set acquisition blocking.
To set the acquisition blocking, proceed as follows:
•
In the main menu of the device display, use the navigation keys to move to
Commands→Equipment→Aq.blkman. update.
•
If several switching devices are available, select the appropriate device (for example, a circuit breaker)
using the navigation keys.
•
Press the Change softkey.
•
Enter the confirmation ID.
•
Confirm the process with the softkey marked OK in the display.
After entering the confirmation ID, the acquisition blocking function is switched on.
