Acting on Sensor Data

This article provides general guidelines for linking sensor statuses to the urgency of taking action.

The urgency to act is divided into five priority levels. Each sensor status is assigned to a corresponding level and is represented by a specific color code.

No to Low Priority Levels

	5 - No Priority	4 - Low Priority
Action	None. All data is good.	Alert the user.
Color code	Green 🟩	Grey 🔲
Alarm statuses
Battery level	Battery OK
Wheel end failure	No failure	No Data
WEM failure	No failure
Temperature sensor failure	No failure
Temperature warning active	No failure
Vibration monitoring status¹	The learning phase is completed. Vibration monitoring is active.	The learning phase is ongoing Inconsistent data

¹	The capability to detect wheel end failure through vibration monitoring is only available for sensors that have completed the learning phase. However, other measurements, like temperature warnings, are still available.

Medium to Critical Priority Levels

	3 - Medium Priority	2 - High Priority	1 - Critical Priority
Action	Need to service soon. Schedule service.	Finish the current route and investigate the issue in a repair and service shop before beginning the next one.	Pullover, do not finish the route and address the issue.
Color code	Orange 🟧	Red 🟥	Red 🟥
Alarm statuses
Battery level	Battery Low level
Wheel end failure		Failure
WEM failure		Piezo Failure WEM Failure Reversed position.
Temperature sensor failure		Failure
Temperature warning active			Failure
Vibration monitoring status

"Maintenance" might not be the best translation here. I think what the guidance is suggesting is to investigate the issue, or in other words, to perform a service check in a repair-shop.
