If the autoreclose function is used with external selection relays according to the prin-
ciples described in figure in “Selection relay supervision” in “BAYCON”, the input
AR_SEL in SWICON is used to select the breaker without any condition checks. When
AR_SEL is set, the output SEL_CLOS is activated directly. The close signal from the
autoreclose function is connected via the OR gate for close commands in a normal way.

The protection functions are normally running independent of the apparatus control
modules. The trip signals from the protection modules included in the control terminal
are connected via the tripping logic function. If a three-phase circuit breaker is used, the
GTRIP general trip signal from the tripping logic can be connected to the same open
output as for the manual control from SWICON via an OR gate (see figure 113). Here,
the OR gate must have the same execution cyclicity as the tripping logic module.
