7 Precautions & maintenance
The WEM200 hardware is maintenance free, non-repairable and users must not attempt to open the device. Firmware
updates will be possible OTA by SKF dealer.
WEM200 may need to be replaced if a fault occurs or when the battery is reaching the end of its life.
If it has to be replaced it is recommended to detach the WEM200 from the vehicle by decommissioning procedure.
No significant performance degradation over time is expected, until the integral battery has reached the end of its life.
Good practice is to be aware of the estimated remaining battery life, investigate any apparently anomalous readings or
status errors and when needed initiate a sensor exchange.
