S&C TripSaver II Installation And Operation

S&C Instruction Sheet 461-502 25
Operation
Local Manual Open—TripSaver II Loadbreak
Function
NOTICE
DO NOT attempt to test the TripSaver II recloser’s
Local Manual Open feature with the recloser in the
horizontal or dropout position. For the Local Manual
Open feature to function properly, the recloser MUST
be installed vertically in the closed position in a cutout
mounting. Repeated use of the Local Manual Open
feature to open the recloser when it is in the horizontal
or dropout position will cause it to enter the Service
Now state after 5 Local Manual Open operations,
rendering the recloser inoperable.
TripSaver II reclosers with rmware versions 1.6, 1.7
and 1.8 have a Local Manual Open (LMO) feature for
loadbreaking without the use of Loadbuster
®
—The S&C
Loadbreak Tool, when this feature is enabled. (A label is
placed inside each TripSaver II recloser shipping carton
for users to label their reclosers that already have the LMO
feature enabled.) This feature provides a manual-operation
sequence that commands the TripSaver II recloser to
open the vacuum-interrupter contacts and drop open.
A TripSaver II recloser must be powered for the LMO
feature to work.
The MODE-SELECTOR lever controls the LMO feature.
The Open Command state is triggered by operating the
MODE-SELECTOR lever X number of times within a
Figure 35. How the LMO feature works.

Note: The trigger values for X (Operations count) and
Y (Operation Time window) are user-configurable using
the TripSaver II Service Center Configuration Software.
Confirm the values of X and Y with your utility.
When the triggering condition has been met, the
TripSaver II recloser starts the open time-delay sequence.
For the next 10 seconds, an “LMO Cancel?” prompt will
appear on the LCD screen for cancellation. The LMO
command can be cancelled by any operation of the
MODE-SELECTOR lever. If the MODE-SELECTOR lever
is operated during this time, an “LMO Cancelled” message
will briefly appear on the LCD screen to indicate the user
has cancelled the operation.
If the command is not cancelled within 10 seconds,
a “WALK AWAY” message will display on the LCD
screen, indicating the start of the 20-second operation
timer intended to allow the operator to comply with any
operating-distance requirements specified by the utility
work practices.
During the walk-away period, the operator can no longer
cancel the open operation. At the end of the walk-away
period, the TripSaver II recloser will open the vacuum-
interrupter contacts to interrupt the load current, then
drop open and reclose the contacts after the tilt sensor
indicates a completed drop-open function. See Figure 35
for a flowchart of the LMO feature sequence.
