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
