set to "On"
The
SYNC_INPRO
output is active when the close command (
CL_COMMAND
or
Synchronize CB) is in progress and it is reset when the close command is reset
or
Maximum Syn time has elapsed.
If the closing conditions are fulfilled during a permitted check time set with
Maximum Syn time, ASGCSYN gives synchro check permission to the breaker
control function block after the closing command signal is delivered. The simplified
configuration block diagram of ASGCSYN with
CLOSE_CB
to the breaker control
function block is shown in
Figure 860
.

Alarms generation
In the synchro check command and auto synchronization control mode operation,
there are alarms for failed closing attempt (
CL_FAIL_AL
) and for a command signal
that remains active too long (
CMD_FAIL_AL
).
In the auto synchronization control mode, the closing command generation is
activated either by the command input
CL_COMMAND
or by the command parameter
Synchronize CB.
