7. Putting Relay into Service
The following procedure must be adhered to when putting the relay into service after finishing
the commissioning tests or maintenance tests.
•
Check that all the external connections are correct.
•
Check the settings of all measuring elements, timers, scheme switches, recordings and clock
are correct.
In particular, when settings are changed temporarily for testing, be sure to restore them.
•
Clear any unnecessary records on faults, events and disturbances which are recorded during
the tests.
•
If dc power has not been supplied to the relay for two days or more, then internal clock may be
cleared soon after restoring the power. This is because the back-up RAM may have
discharged and may contain uncertain data. Set the internal clock again.
•
Press the VIEW
key and check that no failure message is displayed on the
"Auto-supervision" screen.
•
Check that the green "IN SERVICE" LED is lit and no other LEDs are lit on the front panel.
