Informational and Settings Screens
The main power supply capacitors will start to charge, and the Simulation Status
field will display “Charging Caps.” The blue Main Caps Charge indicator at the bottom
of the screen will start to fill up the empty space. The vacuum interrupter contacts will
open after the main capacitors are fully charged. When the interrupter contacts are
open, the full blue “Main Caps Charge” bar recedes immediately. See Figure 134 for an
example of what is displayed on the Functional Test screen during the open interval.

The vacuum interrupter contacts will reclose after the configured open-interval
time has elapsed, and the operating sequence will step to the next Trip operation; the
TripSaver II recloser is now ready for another fault simulation. Perform another temporary
fault simulation by clicking on the button again before the sequence-reset time expires.
Otherwise, the sequence step will reset back to the initial-trip curve.
When the sequence step reaches the last configured Trip operation, an additional
temporary fault simulation within the sequence reset time will release the drop-open
mechanism and the TripSaver II recloser will drop open.
Simulate Permanent Fault. Click on the green Simulate Permanent Fault button to
simulate a permanent fault.
NOTICE
For TripSaver II reclosers with firmware version 1.7 or previous, make sure the trunnion
of the recloser is pointing up when performing testing. Performing testing with the
trunnion facing down, or pointing to the side may cause the TripSaver II recloser to
enter the Service Now state and display the Service Now screen. See the “End
of Interrupting Capability and Service Now Screen” topic in the “Troubleshooting”
section of S&C Instruction Sheet 461-502 and the “Clearing the Service Now LCD
Screen” section on page 112.
Similar to the temporary fault simulation, the main power supply capacitors will start
to charge first, and the Simulation Status field will display “Charging Caps.” After the
main capacitors are fully charged each time, the TripSaver II recloser will open and
