Finding the Cause of a Trip or an Alarm in Critical Cases

Definitions

While operating the circuit breaker, the user may face two critical cases:

• The circuit breaker has tripped automatically, interrupting the power supply.

• The circuit breaker has not tripped, but the TS trip system has detected an alarm:

  • For a high severity alarm, the status bar is red, indicating that urgent corrective action is required.

  • For a medium severity alarm, the status bar is orange, indicating that corrective action needs to be scheduled.

Notification of a Trip or Alarm

A trip or alarm event is signaled:

• On the TS trip system, by the trip cause LEDs, the status bar and the service LED.

• By the SDE fault-trip indication contact.

Active alarms can also be consulted in the following ways:

• On a smartphone with EcoStruxure Power Device app connected to the TS trip system through NFC wireless communication.

• On a PC with EcoStruxure Power Commission software connected to the TS trip system through USB connection.

Identifying the Cause of a Trip or Alarm Using the TS Trip System

In critical situations, the cause of a trip or an alarm can be identified locally by using one of the following:

• The blue fault-trip reset button on the circuit breaker. When the trip button is popped out, the trip has occurred.

• The indication LEDs on the TS trip system.

• A smartphone with EcoStruxure Power Device app installed to get the trip cause, the trip or alarm context, and the circuit breaker ID through NFC wireless communication

Availability of Diagnostic Data After a Trip

Availability of diagnostic data after a trip depends on the TS state:

• If the TS trip system is operative, the trip data is available.

• If the TS trip system is inoperative, no data is directly available. However, some data can be extracted using the NFC wireless communication with the EcoStruxure Power Device app.

The trip cause LEDs, status bar and service LED are powered by the TS internal battery and remain on for 2 hours when there is no other power to the trip system. To switch on the trip cause LEDs or the service LED again after 2 hours, press the button.

Procedure to Follow After Detection of a Trip or Alarm

The procedure to follow after detection of a trip or an alarm depends on the indications provided by the blue fault trip button and the indication LEDs on the TS trip system.
