ally meter alerts
The following information describes the alarms, errors, and warnings for the ally meter.

|---|---|---|---|---|---|---|
| Register Error | Invalid or suspect data received from metrology core. | Invalid or suspect data received from metrology core. | Smart Meter | Investigate if condition continues. | ||
| Actuator Failure | Valve Transition Failure | Set if a valve actuation request could not be completed (that is, the valve is not known to be in the desired final state). | Triggered by failure to successfully complete valve actuation request. | Smart Meter | Investigate. | |
| b (also displays battery icon) | Battery Beyond End of Life | Beyond End of Life | Triggers when the product has reached the end of the expected product life base on years. | Triggers after 20 yrs from install or 21 yrs from date of manufacture. | Smart Meter | Plan scheduled maintenance. |
| b (also displays battery icon) | Battery Near End of Life | Near End of Life | Triggers when the product is near the end of the expected product life based on years. | Triggers after 19.5 yrs from install or 20.5 yrs from date of manufacture. | Smart Meter | Plan scheduled maintenance. |
| Configuration Error | Configuration Error | Indicates one or more calibration factors were not set or that the calibration file has reverted to defaults. | Triggers on a reset if one or more of the calibration factors has not been set. (Should not be seen outside the factory.) | Smart Meter | Investigate, make plans to replace meter soon. | |
| Critical Hardware Warning | Critical Hardware Warning | There may be an issue with peripheral meter hardware, though core metrology functions are not impacted. | Meter fault is detected. | Smart Meter | Investigate. | |
| L | Customer Leak | Continuous Flow | Triggers when the flow rate through the meter meets or exceeds the configured value for the configured period of time. | Triggers when flow rate exceeds configured value for configured time period. The defaults are 0.25 GPM, 0.05 M3/HR, 2 CF/HR in 24hr period. | Smart Meter | Investigate. |
| 0 (zero) | Empty Pipe | Empty Pipe | Triggers when air is detected in the pipe and indicates there is no water in the flow tube. | No water presence detected for 20-40s. | Smart Meter | Investigate. |
| Hardware Failure | Hardware Fault | Severe hardware problem. The meter operation has been compromised. | Meter operation failed. ASIC or system clock failure, calibration data corrupted. | Smart Meter | Replace meter. | |
| H | High Flow | High Flow | Triggers when the flow rate though the meter meets or exceeds the set value for the set time. Could be caused by a broken pipe. | Triggers when flow rate exceeds set value for set period. The default is 25 GPM, 5.7 M3/HR, 200 CF/HR in an hour. | Smart Meter | Investigate. |
| 1 | High Pressure Alarm | High Pressure | Triggers when pressure rises above the set threshold. | Triggers when pressure is above set threshold. The defaults are 200 PSIG, 13.8 Bar over 1 minute. | Smart Meter | Investigate. |
| 3 | High Temperature Alarm | High Temperature | Triggers when the temperature rises above the set range. | Triggers when temperature is above the set temperature. The defaults are 80F, 27C over a minute. | Smart Meter | Investigate. |
| 2 | Low Pressure Alarm | Low Pressure | Triggers when pressure drops below the set threshold. | Triggers when pressure falls below the set threshold. The defaults are 35 PSIG, 2.4 Bar over a minute duration. | Smart Meter | Investigate. |
| Low Primary Battery Volts | Low Metrology Battery Volts | Triggers when voltage supplied to the metrology is running low. | Triggers when volts drops below 2.8V. | Smart Meter | Plan scheduled maintenance. | |
| Low Secondary Battery Volts | Low Valve Battery Volts | Triggers when the voltage supplied at the valve is running low. | Triggers when volts drops below 2.8V. | Smart Meter | Plan scheduled maintenance. | |
| 4 | Low Temperature Alarm (DT101) | Low Temperature | Triggers when the temperature drops below the set range. | Triggers when temperature falls below the set temperature. The defaults are 35F, 2C over a minute. | Smart Meter | Investigate. |
| t | Magnetic Tamper | Magnetic Tamper | Triggers when an attempt to tamper with the meter through the use of a magnet is detected. | Triggers when magnet impacting metrology is detected for 15 or more minutes for 4 cumulative times (1hr). (Not detected when in Empty Pipe.) | Smart Meter | Investigate. |
| Misc Metrology | Misc Metrology | The metrology data is potentially becoming unreliable due to high noise, excessive flow rate, or an excessive number of direction changes. | High noise: There is a potential degradation in meter accuracy caused by an applied external electric current on or in the water line that exceeds the threshold for at least 15 minutes. Excessive flow rate: This threshold is programmable after R1.1.xx. Prior to that release, the maximum allowable flow rate is 55 gpm, the maximum flow physically possible for a 3/4" ally meter. This is potentially caused by water entering the flow from an unexpected source. Excessive direction changes: The threshold and time delay are programmable after the R1.1.xx release. Prior to that release, the maximum allowable number of direction changes is 20 per minute. This condition is checked once per minute. This is potentially caused by water entering the flow from an unexpected source, or electrode failure. | Smart Meter | If this alarm is caused by high noise, it will clear when the noise drops below the programmed threshold, or if the meter enters empty pipe mode. If this alarm is caused by an excessive number of direction changes, it will clear after the number of direction changes per minute falls below the threshold. | |
| Non-Volatile Memory Error | Configuration Error | "Non-Volatile Memory Error". NV memory checksum failed. | NV memory checksum failed. | Smart Meter | Investigate. | |
| Reboot | Meter Reboot | Meter has rebooted. | Meter has rebooted. | Smart Meter | Investigate. | |
| r | Reverse Flow | Reverse Flow | Triggers an alert when there is a consistent reverse flow for a specified period of time. | Triggers when flow is detected in opposite direction. (From the Marketing spreadsheet.) The default flow rate is 1 GPM, 0.22 M3/HR, 8 CF/HR over a minute. | Smart Meter | Investigate. |
| Upgrade Mode | Upgrade Mode | Set if the unit is in a mode that is updating the firmware. | Triggered by receipt of a command to start Firmware Update. | Smart Meter | Investigate. |
