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. In this automatic mode the closing signal
CLOSE_CB is activated automatically once all the closing conditions are satisfied.
If the closing conditions are fulfilled during a permitted check time set with
Maximum Syn time
, ASNSCSYN gives synchro check permission to the circuit-
breaker control CBXCBR after the closing command signal is delivered. The
simplified configuration block diagram of ASNSCSYN with CLOSE_CB to CBXCBR
is shown in
Figure 876
