Putting Relay Into Service - Toshiba GRL100-701B Instruction Manual

7. Putting Relay into Service

The following procedure must be adhered to when putting the relay into service after finishing
commissioning or maintenance tests.
• Check that all 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.
• Reset the counter figures of autoreclose, if necessary. For resetting the count, see Section
4.2.3.4.
• 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.
Whilst the relay is put into service at one terminal by supplying DC power and not yet at the
other terminal, a communication failure will be detected by the automatic monitoring at the
in-service terminal and a red "ALARM" LED is lit. But it will be reset when the relays are put
into service at all terminals.
