What causes ABB SACE Emax 2 Circuit breakers 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 SACE Emax 2 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 SACE Emax 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 SACE Emax 2 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 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.
How to fix communication problems with Ekip Com, Ekip Link, Ekip Signalling or Ekip CI in ABB SACE Emax 2?
If you're experiencing communication problems with Ekip Com, Ekip Link, Ekip Signalling, or Ekip CI in your ABB Circuit breakers, it might be due to the circuit-breaker being in the withdrawn position, Vaux being absent, or modules not inserted properly. To resolve this, insert the modules, set the circuit-breaker to the Connected position, and connect Vaux.
What causes TRIP fail signaling Trip Fail command (BF) in ABB Circuit breakers?
TRIP fail signaling Trip Fail command (BF) in ABB Circuit breakers can be caused by: * One or more of the following conditions: Trip coil not working, status contacts not working, faulty internal wiring. To solve this: 1. If closed, open CB in the manual mode and check changed status. 2. Press iTest, check that the signal has disappeared from the display and the general status of the alarms. 3. Check the conditions of the wiring and internal contacts. 4. Working in safety conditions, close the CB and perform a trip test via the trip unit. Contact ABB if problems persist.
