86 S&C Instruction Sheet 461-504
Using TripSaver
®
II Service Center Configuration Software Version 1.8
Note:
To properly simulate a
Drop Open
operation, the TripSaver II recloser must
be installed in a present-production (“-R10” or “-R11”) S&C cutout mounting. In the
absence of a cutout mounting, always place the TripSaver II recloser horizontally on
a flat surface with the trunnion pointing up when simulating a permanent fault. The
recloser will still go through the entire sequence and release the drop-open mechanism
at the end. However, the drop-open mechanism must be reset manually by either pull-
ing up on the trunnion or by installing the TripSaver II recloser into a cutout mounting.
The drop-open mechanism is fully reset when the trunnion is no longer loosely mov-
able. The
Functional Test
feature was not designed to simulate the “Iced-on-the-pole”
scenario when a TripSaver II recloser is powered by the Service Center Configuration
power module. Do not hold the TripSaver II recloser in the mounting after the drop-
open mechanism has been released when using a power module.
Abort Simulation.
Click on the yellow
Abort Simulation
button to stop the ongo-
ing simulation. The blue “Main Caps Charge” bar recedes after this button is clicked.

How the Local Manual Open Works
TripSaver II reclosers loaded with firmware version 1.8, 1.7, and 1.6 have a
Local Manual
Open (LMO)
feature for loadbreaking without the use of the Loadbuster®—The S&C
Loadbreak Tool. When 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 and installed vertically in a cutout
mounting 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 Y-second
window when the TripSaver II recloser is in the vertical position.
W hen the triggering condition has been met, the TripSaver II recloser
starts the open time-delay sequence. For the next 10 seconds, an “LMO Can-
cel?” prompt will appear on the LCD screen for cancellation. The
LMO
com-
ma nd ca n be ca ncelled by a ny 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.
