Figure 482:
Enabling and blocking logic for CLOSE_ENAD and OPEN_ENAD signals
Disconnector control 29DS and grounding switch control 29GS
Normally, the switch closing is enabled (that is, the
CLOSE_ENAD
signal is TRUE) by
activating the
ENA_CLOSE
input. The input
ITL_BYPASS
can be used for bypassing
this control. The
ITL_BYPASS
input can be used to activate the
CLOSE_ENAD
discarding the
ENA_CLOSE
input state. However, the
BLK_CLOSE
input always blocks
the
CLOSE_ENAD
output.
The CB opening (
OPEN_ENAD
) logic is identical to CB closing logic. The
ITL_BYPASS
input is used in both
CLOSE_ENAD
and
OPEN_ENAD
logics.
