What does the TRACTION SYSTEM (local) fault light signify?

The TRACTION SYSTEM (local) fault light signifies a defective local traction system. In the context of electrical traction systems, the presence of a fault light indicates that there is a malfunction or issue that affects the operation of the traction system. This could involve problems such as a failure within the electrical components, issues with the power supply, or non-standard operational parameters that require attention for safety and efficiency.

When this fault light is illuminated, it serves as an alert to operators and maintenance personnel that immediate investigation and corrective action are necessary before the system can return to safe and reliable operation. Recognizing that the issue lies specifically within the local system allows for targeted troubleshooting and repair, critical for maintaining safe operational conditions and preventing further damage or safety hazards.

The other options do not align with the function of the fault light. For instance, normal operation would not trigger a fault indicator; high pressure in the reservoir relates to pressure management rather than a traction system issue, and emergency procedures being enabled is typically a response to critical failures rather than a status indication from the fault light.
