500W Pit Module receives a successful read from the register.

Low Battery Warning

■

The low battery warning allows the utility to easily identify which water modules are

nearing end-of-life in a mixed population and gives the utility the opportunity to schedule

replacement.

The pit modules include a battery life estimator. The estimator is based on the number of

data packets sent at the various power levels and the age (self-discharge) of the Cellular

500W Pit Module.

Note: The low battery warning is a single flag that is set when the battery has less than

10% remaining capacity, which typically corresponds to 2 years of battery life

remaining. Battery life is evaluated daily at midnight.

Network Mode
