What happens if the AZP or P3 sensor main batteries fail?

This shouldn’t happen as the battery state is reported on regularly to give ample time to change them. However, if the main batteries do approach the end of their life, the sensor goes into back-up power mode before the main batteries actually fail. In back-up power mode, the sensor is powered by its internal back-up battery. The sensor continues to record new data and retains all existing data and settings in its large 2Mb memory. However, it stops communicating with the i2O server. If the AZP sensor main battery fails, this has no effect on the performance of the controller. However, if the P3 sensor main battery fails, the server will be unable to update the control algorithm. This will have a minimal effect as long as the P3 sensor battery is replaced within a reasonable time.
