How to troubleshoot ABB ReliaGear LV SG E2.2 when it is not possible to insert the moving part in the fixed part?
If it is not possible to insert the moving part in the fixed part: * The racking-in/racking-out operation is not performed correctly. See the document 1SDH002013A1001. * The moving part is incompatible with the fixed part. Check the compatibility between the moving part and the fixed part.
How to troubleshoot ABB ReliaGear LV SG E2.2 when opening data not displayed?
If opening data is not displayed on your ABB Circuit breaker, it could be due to no auxiliary power supply and/ or battery low. Correct operating condition.
Why is it not possible to charge the closing springs by means of the gearmotor in ABB ReliaGear LV SG E2.2 Circuit breakers?
If it is not possible to charge the closing springs by means of the gearmotor, it could be due to: * The cables of the gearmotor are not inserted correctly in the terminals. Make sure there is continuity between cable and terminal and if necessary reconnect the cables of the gearmotor to the terminals. * The connections of the power supply circuit are wrong. Check the connections using the relevant wiring diagram. * The circuit-breaker is in disconnected position. Switch the circuit-breaker to the test or connected position. * The gearmotor protection internal fuse has tripped. Replace the fuse. * The gearmotor is damaged. Replace the gearmotor.
What causes ABB ReliaGear LV SG E2.2 not being able to lock in the open position?
If it is not possible to lock the ABB circuit-breaker in the open position: * The opening pushbutton is not being pressed. Press the opening pushbutton and activate the lock. * The lock in open position is defective. Contact ABB.
What causes ABB ReliaGear LV SG E2.2 not being able to remove from the disconnected position?
If it is not possible to remove the ABB circuit-breaker from the disconnected position it can be caused by Fail Safe lock being active. Discharge the closing springs of the command.
What causes Trip times different than expected in ABB Circuit breakers?
If trip times are different than expected in your ABB Circuit breakers, it could be due to: * Wrong threshold/time/curve selected: Correct parameters. * Thermal memory enabled: Disable it if it is not necessary. * Zone selectivity enabled: Disable it if it is not necessary. * Incorrect neutral selection: Modify the neutral selection.
How to troubleshoot display off and/or not backlit in ABB ReliaGear LV SG E2.2?
If the display is off and/or not backlit on your ABB Circuit breaker, it could be due to: * No auxiliary supply or currents lower than minimum turn-on values: Correct operating condition. * Temperature outside range: Correct operating condition.
How to troubleshoot measurements incorrect or absent (current, voltage, etc) in ABB Circuit breakers?
If you find measurements incorrect or absent (current, voltage, etc.) on your ABB Circuit breakers, consider the following possible causes: * Current below the minimum threshold that can be displayed: Correct operating condition. * Incorrect frequency setting: Set frequency. * Harmonic distortion and/or crest factor off range: Correct operating condition. * Incorrect connection between isolation transformer and Measurement module: Check connections between isolation transformer and Measurement module. * Rated voltage parameter setting Error: Set the correct parameters.
Why is the state of CB Position field not aligned with circuit-breaker position in ABB?
The state of the CB Position field might not align with the circuit-breaker position due to the absence of Ekip Com or Ekip Link modules, or contact S75I. To resolve this, check for the presence of Ekip Com or Ekip Link modules and connect contact S75/I.
What causes ABB ReliaGear LV SG E2.2 Circuit breakers not to open when the opening coil is powered?
The ABB circuit-breaker may not open when the opening coil is powered due to: * The operating mechanism being blocked. Contact ABB. * The power supply voltage of the auxiliary circuits being too low. Measure the voltage: it should not be lower than 85 % of the rated voltage of the coil. * The power supply voltage being different from that indicated on the rating plate. Use the correct voltage. * The cables of the coil not being inserted correctly in the terminals. Make sure there is continuity between cable and terminal and if necessary reconnect the cables of the coil to the terminals. * The connections of the power supply circuit being wrong. Check the connections using the relevant wiring diagram. * The opening coil being damaged. Replace the coil.
