However, the presence of these incidences may indicate that a maintainer should visit the site before the problem deteriorates into a system malfunction. The maintainer can be notified through an automated call to an office. Problematic situations can thus be resolved before train movement is hindered. The built-in display provides a quick reference of the health and status of the system. An automated maintenance log provides the maintainer with a list of problems detected since the previous visit to the site.
Diagnostic help is provided with the standard terminal interface and the built-in display.
Diagnostics isolate the problem to the defective board or trackside unit. Parts of the train may be zoomed in to provide an in-depth analysis of trouble some cars. The PC Diagnostic Tool also displays heat profiles of alarming and near-alarming bearings and wheels. Specific channels of analog data can be preset to trigger during train passage for storage and later display. Advanced remote diagnostic aids provide detailed support and solutions to Harmon's customer support team.
