OMNI+ alerts
The following describes the alarms, errors, and warnings for the OMNI+ meter.
| Meter event name | RNI event name | Event description | Event trigger | Event source | Xylem recommended action |
|---|---|---|---|---|---|
| Beyond End of Life | Beyond End of Life | Register has reached the end of its operational life. | For a 10 year battery device, End-of-life alarm becomes active 11 years from date of manufacture or 10 years from Date of Activation whichever is less. Alarm-specific additional data field indicates number of days elapsed after meter reached end-of-life. Alarm is updated once a day at midnight. | Smart Meter | Plan scheduled maintenance. |
| Config Error | Configuration Error | Factory Seal is not set. | Configuration error alarm becomes active when factory seal is not set. Alarm is checked once an hour. | Smart Meter | Investigate. |
| 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. |
| 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. |
| Low Primary Battery | Low Metrology Battery Volts | Low battery. | Battery low voltage alarm becomes active when the battery voltage is below 2.7 V for any 4 consecutive 15 sample periods. | Smart Meter | Investigate. |
| Meter Disconnect Tamper | Meter Disconnect Tamper | Meter disconnected from radio due to cut or broken wire. | Alarm is defined for end-to-end solution but detection is not presently supported by the meter. | Smart Meter | Investigate. |
| Near End of Life | Near End of Life | Register is nearing the end of its operational life. | For a 10 year battery device, Near End of Life alarm becomes active 10.5 years from date of manufacture or 9.5 years from Date of Activation whichever is less. Alarm-specific additional data field indicates number of days remaining before meter reaches end-of-life. Alarm is updated once a day at midnight. | Smart Meter | Plan scheduled maintenance. |
| Non-Volatile Memory Error | Configuration Error | "Non-Volatile Memory Error". NV memory checksum failed. | NV memory checksum failed. | Smart Meter | Reset Firmware Image or start a new firmware load. |
| Reboot | Meter Reboot | Register rebooted. | Reboot alarm is triggered when the register has rebooted. | Smart Meter | Investigate. |
| 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 | Meter is receiving a firmware image. | Alarm is set when the device begins to receive firmware image blocks. It is marked as no longer occurring before executing the flasher app as the last part of a firmware upgrade. Upon booting into the upgraded image, the alarm is in persistent state with start time associated with the reception of Load Start command and stop time associated with the reception of Flash Start command. If after loading the new image, the CRC fails, the Alarm condition is maintained until a Reset Firmware Image is received or a new image is attempted to be loaded. | Smart Meter | Investigate. |
