Acting on sensor data

This article outlines general guidelines for connecting sensor statuses to the urgency of acting.

The urgency to act has been split into five levels referred to as criticality levels (CL). The sensor's different statuses have then been mapped to an appropriate level, along with a color code.

Criticality levels

CL	Action	Color code
1	Immediate Service – Pullover, do not finish the route and address the issue.	Red
2	High Priority – Finish the route and then perform service prior to the next route.	Red
3	Schedule Service – Need to service soon.	Orange
4	Low Priority – Notify the user in UI.	Gray
5	No Priority – All data is good.	Green

Mapping of sensor statuses to criticality levels

CL	Battery level	Wheel end failure	WEM failure	Temperature sensor failure	Temperature warning active	Vibration monitoring status¹
1					Failure
2		Failure	Piezo Failure WEM Failure Reversed position	Failure
3	Battery Low level
4		No Data				Learning phase ongoing² Inconsistent data
5	Battery OK	No failure	No failure	No failure	No failure	Learning phase completed, and vibration monitoring is active

¹ Information on how to determine the sensor’s learning phase status will be made available shortly.

² The ability to detect wheel end failure based on vibration monitoring is only available for sensors that have completed the learning phase. Other measurements, such as temperature warnings, are still available.
