Communication Error Indicators.
• Last Good Read (LGR Flag) Indicates a communication error with the register.
• 100W/100W+ encoder ERT module
If this flag is set for 24 consecutive hours, it initiates a cut cable flag in the extended tampers.
The LGR Flag automatically clears after the ERT module receives a successful read from the
register.
• 100WP pulser ERT module
If the LGR Flag is set two consecutive times, it initiates a Cut Cable Flag in the extended tampers.
The LGR Flag automatically clears after the ERT module receives a successful read from the
register.
Note Last Good Read Flag may be an indicator of a damaged register.
• Extended Tamper Flag (retrievable with two-way communication)
• Low Battery Warning. The 100W/100W+ and 100WP/100WP+ ERT 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 ERT module. The low battery warning allows the utility
to easily identify which ERT modules are nearing end-of-life in a mixed population and gives the
opportunity to schedule replacement.
Note The low battery warning is a single flag set when the battery has less than 10% remaining
capacity, typically 2 years life remaining. Battery life is evaluated daily at midnight.
• Cut Cable Flag
• 100W/100W+ encoder ERT module. The Cut Cable Flag sets if the LGR Flag is active for 24
hours.
• 100WP/100WP+ pulser ERT module. The Cut Cable Flag sets if the LGR Flag is active two
consecutive times.
• The Cut Cable Flag remains active for 40 days in Mobile mode.
• The Cut Cable Flag remains active for 24 hours in Fixed Network mode.
