Stop Clock
This toggles between start/stop the
clock of the relay. The ‘Stop’ stops the
clock in the relay. The ‘Start’ resumes
the clock in the relay.
Save
When connected to the protection
system, the date and time information
on the display is sent to the relay.
Cancel
Returns you to the IPSutil main
window. Any changes to the displayed
information is lost.
There is a blue Time Sync LED mimic on this
dialog box (the LED is displayed as different shading
on a monochrome monitor). When this LED is blue,
the relay is synchronized with the IRIG-B signal
and the Time field is grayed out, indicating that this
field can’t be changed. But the Date field can be
changed (by editing and pressing
Save
).
When the LED is
not blue, the relay is not time-
synchronized and therefore, both the Date and
Time fields can be changed. The time field in the
dialog box is not updated continuously. The time at
which the dialog box was opened is the time that is
displayed and remains as such. This is true whether
the relay is synchronized with the IRIG-B signal or
not. IPSutil is fully Y2K compliant.
