Determination of the checking time for closing
The control module receives information about the circuit breaker status and thus is able
to adjust the command signal to be delivered to the Synchro check function. If the external
command signal CL_COMMAND is kept active longer than necessary, the
CMD_FAIL_AL
alarm output is activated. The alarm indicates that the control module has
not removed the external command signal after the closing operation. To avoid
unnecessary alarms, the duration of the command signal should be set in such a way that
the maximum length of the signal is always below
Maximum Syn time
+ 5s.
