6.11.3 NOTES
1. The PLANT isolate status affects the PLI token in output logic and the "Others"
total on the base display, and also the Ancillary Isolate LED. It does not affect
the Brigade isolate relay or LED. The PLI token is true if the plant is isolated and
false if not isolated. This token may have been programmed to disable the
ancillary relays, module relays or open collector outputs.
2. Option 6 : Bells will be shown on the menu only if the Ancillary 3 relay is
controlled by output logic. In this case if bells are used, they are driven by
module relays (or other).
Thus:
(a) Option 3:ANC3 - is the isolate status of the actual Ancillary 3 relay and
has nothing to do with bells.
(b) Option 6:BELLS - allows the bells to be isolated or de-isolated and has
nothing to do with the Ancillary 3 relay. In this case, isolating the bells will
set the BLI token true in output logic and the BEL token false but have no
effect on the AR3I token. Bells Isolated does not operate the Brigade
Isolate relay.
The bells may also be isolated or de-isolated using the dedicated "BELLS
ISOL" key.
3. If option 6 is not shown (the Ancillary 3 relay is not controlled by output logic) then
option 3 is also a bells isolate/de-isolate function.
Refer also to Section 8.1.2.
