Function blocking
The block signal is checked in the beginning of each program cycle. The blocking signal is received
from the blocking matrix in the function's dedicated input. If the blocking signal is not activated when
the synchronization is OK, a SYN OK signal is generated.
If the blocking signal is active when the SYN OK activates, a BLOCKED signal is generated and the
function does not process the situation further. If the SYN OK function has been activated before the
blocking signal, it resets.
The blocking of the function causes an HMI display event and a-time stamped blocking event with
information of the startup voltage values and its fault type to be issued.
The blocking signal can also be tested in the commissioning phase by a software switch signal when
the relay's testing mode "Enable stage forcing" is activated (
General
→
Device). The variables the
user can set are binary signals from the system.
Setting parameters
NO NOTE! TE! Before these settings can be accessed, a voltage channel (U3 or U4) must be set into
the synchrocheck mode ("SS") in the voltage transformer settings ( Measurements
→
VT Module).
