1.4.4 Maintenance
1.4.4.1 General maintenance
The F650 requires minimum maintenance once it is commissioned into service. F650 is a microprocessor based relay and
its characteristics do not change over time; as such no further functional tests are required. While the F650 performs
continual self-tests, it is recommended that maintenance be scheduled with other system maintenance. This maintenance
can involve in-service, out-of-service, or unscheduled maintenance.
If it is concluded that the relay or one of its modules is of concern, contact GE Multilin or one of its representative for
prompt service.
1.4.4.2 In-service maintenance
1.
Visual verification of the analog value integrity such as voltage and current (in comparison to other devices in the
system).
2.
Visual verification of active alarms, relay display messages and LED indications.
3.
Visual inspection for any damage, corrosion, dust or loose wires.
4.
Event recorder file download with further event analysis.
1.4.4.3 Out-of-service maintenance
1.
Check wiring connections for firmness.
2.
Analog value (current, voltages, analog inputs) injection test and metering accuracy verification. Calibrated test
equipment is required.
3.
Protection element setpoint verification (analog values injection or visual verification of setting file entries against
relay settings).
4.
Contact inputs and outputs verification. This test can be conducted by direct change of state forcing or as part of the
system functional testing.
5.
Visual inspection for any damage, corrosion or dust.
6.
Event recorder file download with further events analysis.
1.4.4.4 Unscheduled maintenance
Unscheduled maintenance such as during a disturbance causing system interruption:
•
View the event recorder and oscillography or fault report for correct operation of inputs,outputs and elements.
1.4.5 Storage
Store the unit indoors in a cool, dry place. If possible, store in the original packaging. Follow the storage temperature range
outlined in the Specifications.
NOTICE
To avoid deterioration of electrolytic capacitors, power up units that are stored in a de-energized
state once per year, for one hour continuously.
