reclose based on the configured operating sequence and eventually release the drop-open
mechanism. The TripSaver II recloser will then drop open and reset.
Clicking on the Simulate Permanent Fault button before the sequence-reset time
expires after a temporary fault simulation is performed will immediately start a perma-
nent fault simulation from the beginning -TCC0.
NOTICE
Clicking either of the two green fault-simulation buttons when in NR or R-NR mode
or when only the Initial Trip curve is applied will cause the recloser to operate “single
shot to drop open.”
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 ongoing
simulation. The blue “Main Caps Charge” bar recedes after this button is clicked.
See Figure 134 on page 97.
How the Local Manual Open Works
TripSaver II reclosers loaded with rmware version 2.0, 1.9, 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.
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.
