How to display phase current readings on GE Multilin 565 Other?
To resolve the issue of no phase current readings displayed on your GE Multilin Other: 1. Verify that the current readings are selected for display by pressing the ACTUAL VALUES key and the LINE DOWN key to view the messages in actual values page 1. 2. Verify that the phase current wiring is correct. 3. Perform the phase current input function check.
What to do if GE Multilin Other display lights but power up message doesn't appear?
If the display lights up but the power up message does not appear on your GE Multilin Other, verify that the control voltage is within the limits indicated on the serial number found on the side of the relay chassis.
What to do if ground fault protection is not energizing trip relay(s) in GE Multilin Other?
To troubleshoot ground fault protection not energizing trip relay(s) in your GE Multilin Other: 1. Verify that ground fault sensing is enabled in setpoints mode. 2. Check that the sensing system selected in setpoints (Residual or Zero sequence) corresponds to your system. 3. For Zero sequence systems, ensure the CT primary ratio entered in setpoints matches the installed CT. 4. Check that the correct ground fault overcurrent pickup has been entered in setpoints. 5. Verify the correct protection curve, pickup level, and curve number are selected for the ground fault level. 6. Ensure the fault current is present longer than the time needed to trip, according to the selected time/overcurrent curve. 7. Check all system wiring. 8. Perform a calibration mode relay test to verify the tr...
What to do if GE Multilin 565 shows 'Illegal Access,' even with the jumper installed?
If you are experiencing ‘Illegal Access,’ even with the jumper installed on your GE Multilin Other, check if access setpoint is disabled via communication with Relaycom®.
How to troubleshoot no MTM communication on GE Multilin Other?
To troubleshoot no MTM communication on your GE Multilin Other: 1. Check MTM communication setpoint. 2. Check MTM default power switch. The MTM can be powered from the PTs or line. The default is line; the switch must be toggled for PT.
Why is analog input alarm not operating on GE Multilin 565?
To troubleshoot why the analog input alarm is not operating on your GE Multilin Other: 1. Verify that the analog input alarm is enabled. 2. Verify that the intended relay has been selected in the setpoints and that the selected relay is correctly wired to the alarm circuit. 3. Read the scaled value of the analog input in the actual values page 2, and ensure that it is above the alarm level setpoint entered in setpoints mode. 4. Read the analog input alarm time delay from the setpoints mode page 5, and ensure that the analog signal is above the trip level for longer than this time.
