How many cars can I query at one time?

How can calibration records be uploaded to EHMS?

What are alerts in EHMS?
Alerts are created when wayside detector readings exceed established thresholds for specific components.

Alerts are available in EHMS and Equipment Health View. Subscribers may receive notifications by email, FTP or MQ.
What are kip readings?
Kip readings measure force on components such as wheels and truck assemblies. One kip equals 1000 pounds.
Who can see detailed alert data?
All users can view alerts, but detailed readings are limited to Umler interested parties such as owners, lessees and maintenance responsible parties.
How are alerts closed?
Alerts close when repairs with a Job Code and Why Made Code are reported or when an inspection is recorded. In some cases, data summary autoclose rules may close related alerts.
How do data summaries get closed?
Depending on the summary type, closure may occur through autoclose criteria, manual closure or may not be available.
How do alert readings move from detectors to EHMS?
Wayside detector readings are processed by IQ, which determines when an alert should open and sends the alert information to EHMS.
What alert information is displayed in EHMS?
EHMS displays data such as car initial, car number, alert type, closure date and detector readings. Additional data is visible only to Umler interested parties.
What is the difference between reporting a repair and reporting an inspection?
Repairs include a Job Code and may close alerts, while inspections use a reason code and do not close related alerts unless each component is individually inspected.
What Job Code or AAR Rule should I use for repairs?
Reporting a wheelset or wheel replacement has the same effect. EHMS closes alerts for related components based on the repair hierarchy.
