Using TripSaver
®
II Service Center Configuration Software Version 1.8
Last Fault Current, A.
This indicates the fundamental-frequency magnitude of the last
fault, in primary amperes, measured just prior to the opening of the vacuum interrupter
contacts. See Figure 102 on page 70.
Status.
This displays the status of the control. See Figure 102. The following status
messages can be displayed.
•
OK:
The TripSaver II recloser is functioning normally and is in the
Idle
state.
•
Waiting to Open VI:
This indicates the vacuum interrupter contacts are waiting to
open.
•
Waiting to Close VI:
This indicates the vacuum interrupter contacts are waiting
to close.
•
Open Interval:
This indicates the state when TripSaver II recloser is in the
Open
Interval
state.
•
Waiting to Drop Open:
This indicates the state when TripSaver II recloser is wait-
ing to drop open.
•
Waiting to Reset Drop-Open:
This indicates the state when TripSaver II recloser is
waiting to reset the drop-open mechanism. This is a relatively short transient state.
•
Dropped Open:
This indicates the TripSaver II recloser has dropped open. This is
a relatively short transient state, after which the status will go back to being “OK”.
•
Error:
This indicates an error has just occurred. This is a transient state and only
temporarily displays immediately after an error event.
•
Service Now:
This appears when a TripSaver II recloser cannot release the drop-open
mechanism after consecutive re-tries, when the vacuum interrupter contacts cannot
open after consecutive re-tries, or when a TripSaver II recloser is no longer capable
of interrupting a fault when remaining contact wear is at 0%. When a TripSaver II
recloser enters the
Service Now
state, the LCD will be locked with a special
Service
Now
screen: the right side of the screen will display the vacuum interrupter status
(“O” for Open; “I” for Closed; “X” for an error situation when the recloser cannot sense
the vacuum interrupter status.) and the left side of the screen will display an “!” sym-
bol, indicating immediate attention is needed. Rotating the MODE SELECTOR lever,
applying a 9-Volt Lithium L522 battery, or applying the Service Center Configurability
power module will not unlock the screen. The TripSaver II recloser must be returned
to S&C Electric Company for service.
Note:
The
Status
field displays “OK” most of the time during configuration.
Changes in status will be seen during a functional test. However, some of the fast
transient events may not be captured on the screen. To optimize the performance of
communications system, the software is designed to pull status information from the
connected TripSaver II recloser only once per second. Therefore, some fast transient
events may have already expired by the time TripSaver II recloser starts to transmit its
latest status information to the software.
