Supervision of the circuit breaker
ready information
Because the supervising unit of the circuit breaker en-
ergy store operates often after the first fast switch off
(see also para. 3.1.2), the signal "C.B. not AR-ready" is
not evaluated anymore after an introduced reclosing.
The C.B. ready information is checked before an intro-
duced AR for further ARs. There will be a reclosing
when the "circuit breaker ready" had been given before
the begin of the reclosing cycle. If not, the LED CB
flashes and the display shows „S/E?“.
4.5.9
External blocking
The AR-relay is blocked if the the external AR-block input
is activated.
When the reclosing shot is set to „EXIT“, the
MRIK3
can
also be blocked at site. (see chapter 5.4.13)
