| Meter event name | RNI event name | Event description | Event trigger | Event source | Xylem recommended action |
|---|---|---|---|---|---|
| Brownout | Brown Out | The voltage for the meter has dropped below the brownout threshold for a length of time. | Each time the FlexNet module samples the voltage registers from the meter, the minimum voltage is compared to the “Brownout Voltage Threshold”. If the minimum voltage is lower than the threshold, the brownout bit is set. The brownout bit is cleared when the voltage average window resets. The first sample time in which the FlexNet module reads a voltage that sets the brownout condition an optional alarm message is sent. As a backup, in case that transmission was not received, the brownout bit is set in each meter read message until the voltage average window expires even if the brownout line condition has already cleared. | Radio Endpoint | Investigate reason for low voltage in field. Alarm reset at end of the VAW. |
| Click Count | N/A | The number of times AC voltage gaps that do not result in a power fail alarm. | A click event occurs where the power is lost long enough to detect the loss (6-240 line cycles meter configuration setting) but not for continued loss of power that crosses the Outage Time threshold where meter would then go into last gasp. The click counter field increments each time a short duration voltage outage occurs (the outage is greater than the click count threshold setting but shorter than the Outage Time Threshold setting). The counter goes to 255 before resetting back to zero. | Radio Endpoint | Investigate reason for momentary voltage issues. |
| Clock Error | Metrology Clock Error | Clock error. The meter's clock failed. | This event is set to indicate that meter lost its date and time. The Clock Error bit in Standard Status 1 in ST03. This flag is cleared when date and time is set in the meter. | Metrology | Consult Honeywell documentation. |
| Configuration Error | Configuration Error | This indicates a problem with the meter’s metrology configuration or program. The meter can usually be reprogrammed using Elster Electricity meter support software to correct the errors. | C1219 standard error | Metrology | Review and reconfigure metrology per manufacturer. |
| Demand Overload | Metrology Demand Overload | Demand Overload. The demand value is higher than the programmed value. | The demand value is higher than the programmed value. | Metrology | Reprogram metrology or replace meter. |
| High Temperature / Hot Socket | High Temperature Detected | High Temperature. The meter's internal temperature has exceeded the configured temperature threshold. | The FlexNet microprocessor uses an embedded temperature sensor to measure the ambient temperature inside of the meter plastic enclosure. The temperature is sampled every 10 seconds. If the temperature read exceeds the High Temperature threshold, ten alarm messages with the high temperature alarm bit set are immediately transmitted. The high temperature threshold defaults to 85°C and is programmable. Configuring the threshold less than 70°C fixes the threshold to 85°C. The high temperature alarm feature also includes hysteresis. After the temperature threshold is exceeded and temperature alarm messages are transmitted, the temperature must drop at least 15 degrees below the temperature threshold before the high temperature alarm function is re-enabled. This avoids having SmartPoint modules send many high temperature alarms when the ambient temperature inside of the meter is hovering around the high temperature threshold. The transmission mode for each alarm transmission depends on the SmartPoint module configuration. Typically high temperature alarm messages are transmitted on the priority channel. | Radio Endpoint | On-site visit is required to investigate the meter socket and service. |
| High Voltage | Over Voltage | High Voltage. The meter has detected that the voltage exceeds the high voltage threshold. | Each time the SmartPoint module samples the voltage registers from the meter, the maximum voltage is compared to the High Voltage Threshold. If the maximum voltage is greater than the threshold, the over voltage bit is set. The over voltage bit is cleared when the voltage average window resets. The first sample time the SmartPoint module detects an over voltage condition, an optional alarm message is sent if real time alarm for over voltage is enabled. As a backup, in case that transmission was not received, the over voltage bit is set in each meter read message until the voltage average window expires, even if the over voltage condition has already cleared. | Radio Endpoint | On-site visit is required to investigate the meter socket and service. |
| In-Time Sync | Time Adjusted | In-Time Sync. The endpoint or device's time synchronizes with the tower. | The endpoint or device's time is not synchronized with the tower. | Radio Endpoint | No user action is required. This is a status indication only. |
| Low Battery Error | Metrology Low Battery | Low Battery Error. | The meter's battery has low voltage. This will also appear if the battery is missing. | Metrology | If meter has a battery, schedule field visit for battery replacement. |
| Low Loss Potential | Metrology Low Loss Potential | Low Loss Potential. The meter is missing phase. | Voltage on phase A has dropped below the programmable set point. | Metrology | Self-correcting. Will reset if voltage goes back above set point. See manufacturer documentation. |
| Measurement Error | Measurement Error | Measurement error. | Temporary issue measuring energy. | Metrology | Self-correcting. Contact metrology manufacturer if the issue persists. |
| Meter Read Failure | Meter Read Failure | Meter Read Failure. The meter could not be read due to no response, bad CRC/Checksum/Parity, or invalid data. | Meter Read Failure (MRF) indications are set internally when any metrology I/O operation fails. A MRF failure is communicated to the RNI on the next supervisory transmit event when an MRF alarm is sent instead of a reading message. | Radio Endpoint | Self-resolving. Replace the meter if the alarm continues repeatedly. |
| Meter Unprogrammed | Meter Unprogrammed | Meter Unprogrammed. The meter is not programmed currently. | C1219 standard error | Metrology | Reprogram metrology or replace meter. |
| NONVOL Error | Metrology Non Volatile Memory Error | NONVOL Error. The meter cannot access the EEPROM. | The metrology cannot access the nonvolatile ram. Meter will show Er 000 200 on the display. Metrology will set NONVOL_MEM_FAILURE_FLAG in STD TBL 3 in the meter. | Metrology | Replace meter recommended by Aclara. |
| Over Class Amps | Over Current | Over Class Amps. Set when the current flow exceeds the rated class amps. | Each time the FlexNet module samples the current level registers from the meter, the maximum current is compared to the “High Current Threshold”. If the maximum current is greater than the threshold, the over class amps bit is set. The overclass amps bit is cleared when the voltage average window resets. | Radio Endpoint | On-site visit is required to investigate the meter socket and service. |
| Power Fail | Power Fail | The meter has lost power. | Each time the FlexNet module detects that the power monitor signal is de-asserted, the module enters a low power state and enters a hold-off period equal to the number of seconds stored as the “Outage Time Threshold”. The Outage Time Threshold is programmable in eight second increments and can be configured from 8 to 120 seconds. While the FlexNet module is in its low power state it continues to monitor the status of both power monitor signals. If either power monitor signal is re-asserted while the module is still in the hold-off period, the FlexNet module exits the low power state and continues to operate normally. No power fail transmissions are sent in this case. | Radio Endpoint | The alarm will auto resolve when the AC power is restored. If the power has been restored but the alarm persists then an on-site visit is required to investigate the status of the meter. |
| Power Restore | N/A - Restore is marked as the end of the Power Fail event | Power Restore. AC power is detected for a longer period than the configured Restore Time threshold after a loss of power occurred. | Upon power-on-reset (POR), the FlexNet module waits until the power monitor signal is asserted. Once the power monitor signal is asserted, the FlexNet module enters a hold-off time equal to the number of seconds stored as the “Restoral Time Threshold”. The Restoral Time Threshold is configurable in eight second increments and can be configured from 8 to 120 seconds. | Radio Endpoint | No user action required. This is a status indication only. |
| Processor Resets | N/A | Processor resets. The number of times the meter's processor has been reset. | The processor resets field is a modulo-16 counter that increments each time the FlexNet microprocessor is reset. Seeing this field increase is not necessarily an indication of a problem since this field will increment each time the power fails for longer than the Outage Time Threshold. A high value in this field only indicates a potential problem when the unit has not also been reporting a high number of power failures. | Radio Endpoint | Monitor for excessive resets. |
| RAM Failure | RAM Failed | RAM Failed. The RAM checksum test failed during bootup. | The RAM checksum test failed during boot-up. Counter that increments once every time the microprocessor is reset. Cleared by a static setup message. | Metrology | Replace meter. |
| Register Memory Error | The meter had a problem reading internal register data. | Reported by metrology. | Metrology | Investigate. | |
| Reverse Energy | Reverse Energy | Reverse energy. Reverse power flow has been detected. | Reverse power flow has been detected continuously for five minutes Each time the FlexNet module samples the voltage registers from the meter (90-sec), the reverse current flag will be checked. The first sample time in which the FlexNet module detects a reverse flow bit an optional alarm message will be sent. As a backup, in case that transmission was not received, the reverse energy bit is set in each meter read message until the voltage average window (VAW) expires even if the reverse energy condition has already cleared. If the meter’s reverse energy indication spans multiple VAW timeouts, an optional reverse energy alarm once during each VAW. | Radio Endpoint | Investigate the reason for the alarm. |
| ROM Failure | Metrology ROM Error | ROM failure. The meter had a problem accessing its nonvolatile EEPROM. | The meter cannot access the EEPROM. | Metrology | Replace meter. |
| RX Calibration Errors/Receiver Calibration | N/A | RX Calibration Errors/Receiver Calibration. The number of times the receiver could not calibrate. | The RX Calibration errors field is a modulo-16 counter that increments each time the mPass receiver fails to calibrate. For a receiver that is operating under normal operating temperatures, this field should never be non-zero. | Radio Endpoint | Investigate the reason for the alarm. |
| Single Phase Outage | Single Phase Fail | Single phase outage. | For a meter that has multiple phase voltages, the module has the ability to detect and report single phase outages. A single phase outage is defined as one of the power monitor signals from the meter reading less than 96 volts. The single phase outage detection is an edge sensitive. This means that the device must have been operating normal power prior to a single phase dropping out in order for the device to enter the single phase outage alarm messaging sequence. When a single phase outage event occurs the module will schedule three alarm messages to be sent with the single phase fail bit set. The power fail bit will not be set in these messages. | Metrology | The alarm will auto resolve when the AC power is restored to this phase. If the power has been restored but the alarm persists then an on-site visit is required to investigate the status of the meter. |
| Tamper | Tamper | Tamper. The meter's orientation has been moved or the cover has been opened. | Each time the FlexNet module detects a de-asserted power monitor signal, the electronic tamper algorithm starts. The electronic tamper detection monitors a hardware vibration sensor to determine if the meter has been removed from the socket. If the meter was removed from the socket, the FlexNet module will immediately send up to four power fail transmissions with the tamper bit set. | Radio Endpoint | Doublecheck if there was a work order for this time. If not, on-site visit is required to investigate the status of the meter. |
| TX Lock Errors/Synthesizer Lock Failures | N/A | TX Lock Errors/Synthesizer Lock Failures. The number of times the transmitter could not lock to a frequency. | The TX Lock errors field is a modulo-16 counter that increments each time the transmit synthesizer fails to lock. For a transmitter that is operating under normal operating temperatures, this field should never be non-zero. | Radio Endpoint | Investigate the reason for the alarm. |

If the minimum voltage is lower than the threshold, the brownout bit is set. The brownout bit is cleared when the voltage average window resets. As stated above, the first sample time in which the FlexNet module reads a voltage that sets the brownout condition an optional alarm message is sent. As a backup, in case that transmission was not received, the brownout bit is set in each meter read message until the voltage average window expires even if the brownout line condition has already cleared. | Radio Endpoint | Investigate reason for low voltage in field. Alarm reset at end of the VAW. |

| Power Fail | Power Fail | Power Fail. The meter does not have any AC power. | Each time the FlexNet module detects that the power monitor signal is de-asserted, the module enters a low power state and enters a hold-off period equal to the number of seconds stored as the “Outage Time Threshold”. The Outage Time Threshold is programmable in eight second increments and can be configured from 8 to 120 seconds.

If either power monitor signal is re-asserted while the module is still in the hold-off period, the FlexNet module exits the low power state and continues to operate normally. No power fail transmissions are sent in this case. If the module completes its programmed hold-off time and the power monitor signals from the meter are still de-asserted, the module will then write the time of last power fail to flash memory and send up to five power fail transmissions.

If the meter cannot be read the meter read failure flag will be set and sent to identify an issue with collecting the reading value. For example, a wheel is between digits 3 and 4 during the reading the radio cannot read the value. | Radio Endpoint | Self-resolving. Replace the meter if the alarm continues repeatedly. |
| Meter Unprogrammed | Meter Unprogrammed | Meter Unprogrammed. The meter is not programmed currently. | C1219 standard error | Metrology | Reprogram metrology or replace meter. |
| Power Fail | Power Fail | Power Fail. The meter does not have any AC power. | The meter transmits 4 alarms unless power comes back during the transmission/dither period, or the meter does not have enough reserve capacitor charge to allow it (for example, there is a brief power restore not allowing sufficient charging time, followed by another power fail). | Radio Endpoint | The alarm will auto resolve when the AC power is restored. If the power has been restored but the alarm persists then an on-site visit is required to investigate the status of the meter. |
| Power Restore | N/A - Restore is marked as the end of the Power Fail event | Power Restore. AC power is detected for a longer period than the configured Restore Time threshold after a loss of power occurred. | AC power is detected after a power fail. | Radio Endpoint | No action necessary. |
| RAM Failure | RAM Failed | RAM Failed. The RAM checksum test failed during bootup. | RAM Error bit in Standard Status 1 is reported as an immediate alarm. | Metrology | Replace meter. |
