Service
When the vacuum interrupter reaches the end of its useful
life, TripSaver Dropout Recloser will go into “Service Now”
mode. It will drop into the open position and will not reset,
blocking the vacuum interrupter in the open position and
the operating mechanism in the dropout position. TripSaver
Dropout Recloser cannot be closed into the mounting and will
need to be removed and returned to the factory for service.
Contact your nearest S&C Sales Office. Reverse the procedure
outlined in Step 3 on pages 9 through 11 to the remove
TripSaver Dropout Recloser from the cutout mounting.
Under Ice Conditions
Ice hood, suffix “-H1,” can be added to increase ice-breaking
capability from
1/8
to
1/4
-inch. See Figure 16.
If, during a fault condition, TripSaver Dropout Recloser
cannot drop out of the mounting because of excessive ice
buildup, the operating sequence will be:
•
In the AUTO mode:
Open (fast)–5 sec.–
Close–Open (TCC)–5 sec.–
[Close–Open (fast)–5 sec.]–No Reclose.
Sequence in brackets repeats four times.
•
In the NR mode:
Open (fast)–5 sec.–No Reclose.
At the end of either operating sequence above, the Trip-
Saver Dropout Recloser will not have been reset and will be
locked out with the contacts in the open position. The unit
must be returned to S&C to be reset.
