S&C TripSaver II User Manual

130 S&C Instruction Sheet 461-504
Appendix D
A SCADA communication can place a TripSaver II recloser with the Extended Open
Interval option (option “-O”) into Remote Non-Reclose (R-NR) mode if remote com-
munications are enabled via the TripSaver II Communications Gateway. With the addition
of the new NR-Standard, Cold Wakeup, and Post Fault Wakeup curves, and with the ability
to turn off the Temporary Auto mode, the TripSaver II recloser may behave differently
from what is expected.
Table 3 explains which curve is active depending on the MODE-SELECTOR lever
position, the R-NR mode, the conditions the recloser is “waking up” from when being
closed into its mounting, and whether the Temporary Auto mode has been disabled
under the R-NR Functions menu.

● The Temporary Auto mode can be enabled
or disabled using the Disable Temporary Auto
Post-Fault Wakeup mode in Remote-NR button
found in the R-NR Functions menu. This ONLY
disables Temporary Auto mode when the switch
is in R-NR mode with the lever in the Up position.
