Screen Name Description
— Hold Previous
Screen
The Normal screen is displayed.
Blue Screen A blue screen is displayed. When the Identify command is given by the communications gateway,
the LCD screen will update to all blue, then all white, and repeat. This can help to identify a
specific TripSaver II recloser.
“Primary Normal”
Screen
For standard TripSaver II reclosers, four operating parameters are displayed: Vacuum Interrupter
status (Open or Closed), Mode Selector status (Auto or NR), Overload indicator at the bottom
left corner (Symbol “X”), and Service Soon indicator at the bottom right corner (Symbol “•”). The
Overload indicator will appear when the TripSaver II recloser has dropped open because of an
overload. The Service Soon indicator will appear when the vacuum interrupter reaches 10% of the
remaining contact wear.
For Extended Open Interval option-enabled TripSaver II reclosers (catalog number with “-O”
suffix option), an additional operating parameter may be displayed: Battery Status indicator
(Symbol “!”) to the left of the Service Soon indicator. The Battery Status indicator will appear
when the control detects a battery problem.
“Secondary Normal”
Screen
Three operating parameters are displayed: Vacuum Interrupter status at the upper left corner
(Symbol “O” for open, Symbol “I” for closed), Number of Open operations at the upper right
corner, and Remaining Contact Wear in bar chart format at the bottom of the screen. (A full blue
bar indicates 100% remaining contact wear. The blue bar shortens in length leftward as remaining
contact wear decreases.)
Load Current The load current in primary amperes, measured just before the recloser loses power, is displayed.
Last Fault Magnitude The fundamental-frequency magnitude of the last fault current in primary amperes, measured just
prior to the opening of the vacuum interrupter, is displayed. The fault current unit is A for faults
smaller than 1000 A, and kA with two decimals for faults greater or equal to 1000 A. This was
done because of the limited horizontal space on the LCD. Note: When selected, if the recloser
drops open because of an overload event, the Primary Normal screen will be displayed instead.
Vacuum Interrupter
Status
The most-recent state of the vacuum interrupter–either “Open” or “Closed”–is displayed.
Mode Selector
Status
The most-recent mode of operation–either “Auto”, “NR”, or “R-NR”–is displayed.
Number of Open
Operations
The total vacuum interrupter Open operations is displayed.
