Monitoring the Tripping Circuit - EasyPact MVS TS Trip System User Guide

Presentation

When the TS trip system is energized, it provides constant monitoring of the following:

The internal tripping circuit
.
The connection of the internal sensors (internal current transformers, sensor plug, performer plug)
.
The connection of the circuit breaker tripping voltage release (MITOP) to the TS trip system
.

NOTE: The mechanism is not monitored. It is recommended to perform preventive maintenance as proposed by Schneider Electric.

Availability

Monitoring the tripping circuit function of the TS trip system is available on TS 2.0S, 5.0S, and 6.0S trip system.

Operating Principle: Ready LED

TBD: role of satus bar, role of the Ready LED to indicate status of the tripping circuit TBC with experts

To do: Graphics MVS TS

A. Ready LED

The result of the monitoring is indicated by the ready LED on the front face of the TS trip system, as follows:

The ready LED is flashing green: the internal tripping circuit of the circuit breaker is functioning correctly.
The ready LED is off:
- The TS trip system is not powered.
- Or there is a detected incident in the tripping circuit.

Circuit Breaker Status

Following the detection of an incident in the tripping circuit the circuit breaker may be tripped or not, depending on the type of incident detected.

Tripping Data and Availability

The following data about the tripping function is logged by the TS trip system:

Total number of trips
The recent trip cause

The tripping data is available with:

The EcoStruxure Power Commission software for last 30 trip records.
The EcoStruxure Power Device app through NFC communication.

Predefined Events

The monitoring of the tripping circuit generates the following events:

Code	Event	History	Severity
0x6407 (25607)	Self diagnostic trip	Trip	High
0x6433 (25651)	Phase current transformer sensors open circuit trip	Trip	High
0x1400 (5120)	Control unit self test major malfunction 1	Diagnostic	High
0x1402 (5122)	Internal current sensor disconnected	Diagnostic	High
0x1404 (5124)	Control unit self test major malfunction 2	Diagnostic	High
0x1405 (5125)	Control unit self test major malfunction 3	Diagnostic	High
0x1406 (5126)	Control unit self test major malfunction 4	Diagnostic	High
0x1416 (5142)	Control unit self test major malfunction 5	Diagnostic	High
0x1409 (5129)	Unable to read sensor plug	Diagnostic	High
0x1518 (5400)	Control unit self test major malfunction 6	Diagnostic	High

Predefined events cannot be modified by the user. For general information about events, refer to the Event Management.

Recommended Actions

Code	Event	Recommended actions
0x6407 (25607)	Self diagnostic trip	Plan to replace the TS trip system.
0x6433 (25651)	Phase current transformer sensors open circuit trip	Plan to replace the circuit breaker. TBC
0x1400 (5120)	Control unit self test major malfunction 1	Plan to replace the TS trip system.
0x1402 (5122)	Internal current sensor disconnected	Plan to replace the circuit breaker.
0x1404 (5124)	Control unit self test major malfunction 2	Plan to replace the TS trip system.
0x1405 (5125)	Control unit self test major malfunction 3	Plan to replace the TS trip system.
0x1406 (5126)	Control unit self test major malfunction 4	Plan to replace the TS trip system.
0x1416 (5142)	Control unit self test major malfunction 5	Plan to replace the TS trip system.
0x1409 (5129)	Unable to read sensor plug	Check connection of the sensor plug and performer plug. If the connection is good but the event is detected again, replace the sensor plug or the trip system.
0x1518 (5400)	Control unit self test major malfunction 6	Plan to replace the TS trip system.

Contact Schneider Electric Support or your Schneider Electric Services representative for more information about who can carry out the recommended actions.
