7.5 DEAD TIME CONTROL
When the setting CS AR Immediate is enabled, immediate r

that both sides of the circuit breaker are live and in synchronism at any time after the dead time has started. This
allows for quicker load restoration, as it is not necessary to wait for the full dead time to expire.
If CS AR Immediate is disabled, or neither Line nor Bus are live, the dead timer will continue to run, if the Dead
Time Enabled signal is high. The Dead Time Enabled function could be mapped to an opto-input to indicate that
the circuit breaker is healthy. Mapping the Dead Time Enabled function in PSL increases the flexibility by allowing it
