GE Feeder Management Relay 750 Instruction Manual

GE Multilin 750/760 Feeder Management Relay 8-98 COMMISSIONING TESTS 8.2 INPUTS/OUTPUTS88.2.3 OUTPUT RELAYS1. Enter the following settings under the S8 TESTING Ö OUTPUT RELAYS subheading:FORCE OUTPUT RELAYS FUNCTION: "Enabled"FORCE 1 TRIP RELAY: "De-energized"FORCE 2 CLOSE RELAY: "De-energized"FORCE 3 AUXILIARY RELAY: "De-energized"FORCE 4 AUXILIARY RELAY: "De-energized"FORCE 5 AUXILIARY RELAY: "De-energized"FORCE 6 AUXILIARY RELAY: "De-energized"FORCE 7 AUXILIARY RELAY: "De-energized"FORCE 8 SELF-TEST RELAY: "De-energized"FORCE SOLID STATE OUTPUT: "De-energized"2. Using a multimeter, check that all output relays are de-energized (i.e. N.O. contacts open, N.C. contacts closed).3. Make the following setting change: S8 TESTING Ö OUTPUT RELAYS ÖØ FORCE 1 TRIP RELAY: "Energized".4. Check that the Trip output is energized (i.e. N.O. contacts closed), and the Trip LED is illuminated.5. Make the following setting change: S8 TESTING Ö OUTPUT RELAYS ÖØ FORCE 1 TRIP RELAY: "De-energized".6. Repeat Steps 3 through 5 for Output Relays 2 through 8 inclusive.7. Observing polarity, connect a minimum 5 V DC source in series with a limiting resistor that will permit a minimum cur-rent of 100 mA, in series with the Solid State output. Observing polarity, connect a DC voltmeter across the limitingresistor. Check there is no voltage displayed on the voltmeter.8. Change setting to: S8 TESTING Ö OUTPUT RELAYS ÖØ FORCE SOLID STATE OUTPUT: "Energized".9. Check that a voltage has appeared on the voltmeter. Turn off the source and disconnect the test wiring.10. Change setting to: S8 TESTING Ö OUTPUT RELAYS ÖØ FORCE SOLID STATE OUTPUT: "De-energized".11. Change setting to: S8 TESTING Ö OUTPUT RELAYS Ö FORCE OUTPUT RELAYS FUNCTION: "Disabled".
