S&C TripSaver II Installation And Operation

S&C Instruction Sheet 461-502 29
Troubleshooting
In Mounting with Contacts Open
The TripSaver II recloser is capable of dropping open
under 3⁄4–inch (19 mm) of ice formation. If the TripSaverII
recloser does not drop open at the end of its operating
sequence because of excessive ice build-up or for any
other reason, it will remain in the upright position, with
the vacuum interrupter in the Open position and the
drop-open mechanism unlatched. The interrupter and
drop-open mechanism will not reset automatically. The
LCD screen will show the vacuum interrupter with an
Open state. Use a Loadbuster tool to open the TripSaverII
recloser and remove it from the mounting. The operating
mechanism and vacuum interrupter must then be manually
reset. See the next section for the resetting procedure.
Note: When the ambient temperature is below -30°C
(-22°F), the LCD will not refresh (complete LCD informa-
tion can be read after refreshing the LCD screen with a
9-volt Lithium L522 battery).
Manually Resetting a TripSaver II Recloser
DANGER
The TripSaver II recloser MUST be removed from the
pole before a manual reset is attempted. Attempting to
reset a TripSaver II recloser that has not dropped open
because of icing or other reasons while it is installed on
the pole using a battery will reset the recloser’s vacuum
interrupter but NOT the drop-open mechanism. (This
state can be confirmed if the recloser’s LCD screen
reads “VI Open” but the recloser appears closed.) The
trunnion of the TripSaver II recloser in this state is still
loose and can cause the TripSaver II recloser to swing
out of the mounting when the blockage is removed
or when it is manually operated, potentially causing
arcing. Therefore, the TripSaver II recloser MUST be
removed from the pole and placed in the horizontal
position to reset both the vacuum interrupter AND
the drop-open mechanism at the same time. Failure
to remove the recloser from the pole before manually
resetting can lead to arcing, injury, or death.
If a TripSaver II recloser does not drop open when it
should, the vacuum interrupter will be locked in the Open
position; it will not reset automatically. To manually reset
the TripSaver II recloser:
STEP 1. Remove the TripSaver II recloser from the
mounting using a Loadbuster tool.
STEP 2. Place the recloser horizontal on a at surface
with the trunnion pointing up. See Figure 42.
STEP 3. Connect a 9-Volt Lithium L522 battery to the
battery-reset contacts located on the bottom of
the device. In about 5 to 7 seconds, the Primary
Normal screen will refresh, and the drop-open
latch will reset with a clicking sound. Polarity of
the battery does not matter. See Figure 42.
