EXECUTE command. This must now come together with the OPEN or
CLOSE direction to activate either EXE_OPEN or EXE_CLOS. The con-
nections between SWICON and the output board are shown in Fig. 9.

Fig. 9 Connection of select and execute signals to the command out-
put board from SWICON
Before a selection output is activated, SWICON checks the blocking
(BLK_OPEN/CLOS) and interlocking (INT_LOCK) inputs. After activa-
tion of the selection outputs, the selection timer (T_SEL) starts. When the
feedback select signal does not come in time, SWICON sets the
SEL_ERR output. After the execute outputs are activated, it sets the
CMD_ERR if the position indication does not indicate a start in the posi-
tion change, before the time T_START has elapsed.
Automatic operation is included in SWICON. It has an input for bay
information concerning permission for automatic operation (AU_OP_V).
It also has an output that indicates permission per apparatus (AU_OP_P).
For synchro-check, SWICON has two versions. One version (SWICONA)
is for a synchro-check relay that checks the synchronisation condition
continuously and gives a signal on SY_OK if there is synchronism, see
Fig. 28. This is the normal application when the internal synchro-check
function is used. To close the breaker, SWICON can activate the
EXE_CLOS output at the activation of the SY_OK signal, when the
CLOSE and EXECUTE inputs are already set and also when the
SEL_CLOS output is set. The SY_RUN input is set to FIXD-ON. If not,
the SY_OK input is used; it also sets to FIXD-ON.
