Division 4.3.13 Monitoring and diagnostic concepts

The functions and equipment specified in this TSI and repeated below, shall be monitored because they present an important risk to safety in the event of a failure or operating fault:

• failure of the driver vigilance device (Section 4.2.2)

• control-command sub-system information (Section 4.2.4)

• door operation (Section 4.2.6)

• running gear instability detection (Section 4.2.10)

• on-board hot-box detection system (Section 4.2.11)

• activation of the passenger alarm (Section 4.2.12)

• fault in the brake system (Section 4.3.6)

• derailment detection (Section 4.3.10)

• fire detection (Section 4.3.11).

This monitoring shall be continuous, or at a suitable frequency to ensure reliable detection of failure in good time. The system shall also be linked to the on-board data recorder to allow the necessary traceability.

Indication to the driver shall be made of such detection, and shall require acknowledgement by the driver. Automatic action shall be required where a fault can have grave consequences for safety.
