FAST PATH:
The pushbuttons, Tag, Block and Bypass Block are used for both breakers (contactor) and
switches when selected in the SLD. Only one component at the time can be selected in the
SLD.
FAST PATH:
Tagging, blocking, or bypassing block can be performed in Local Mode, and only when the
component (breaker (contactor) or switch) is selected in the SLD. The applied action of
tagging, blocking or bypassing block is retained for this component after it’s been
deselected. To change the status of the applied action, the component need be reselected.
FAST PATH:
The Local Mode control allows programming of separate pair of PBs for Open and Close
commands to breakers (contactor) and for Open and Close commands to switches. If
desired, one pair of pushbuttons can be programmed for Open and Close commands to
both breakers (contactor) and switches.
