| Bad Password | Metrology Bad Password | Bad Password. | The number of allowable password attempts has been exceeded. Bad Password bit in Standard Status1 of ST03. | Radio Endpoint | Monitor. |
| Brownout | Brown Out | The voltage for the meter has dropped below the brownout threshold for a length of time. | Each time the SmartPoint 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. | Radio Endpoint | Investigate reason for low voltage in field. Alarm reset at end of the VAW. |
| Click Count | N/A | The meter is currently undergoing transformer breaker operations. | 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 possible source of momentary outages in field. Change the voltage source to reduce transformer breaker operations. |
| Clock Error | Metrology Clock Error | Clock error. | 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 Aclara documentation. |
| 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. The Meter will display CA 000 400The Demand Overload, Leading kVArh, and Received kWh cautions remain set in the meter until cleared by a manual demand reset. Demand Overload bit in Standard Status1 of ST03. | Metrology | Reprogram metrology or replace meter. |
| Flash Code Error | Metrology Code Error | Flash Code Error. | Error occurred in code stored in flash memory. Kv2c std table 3. ED_MFG_STATUS_1 (0X40) (Set = 1, Clear = 0) | Metrology | Replace meter. |
| Flash Data Error | Metrology Data Error | Flash Data Error. | Error occurred in data stored in flash memory. Kv2c std table 3. ED_MFG_STATUS_1 (0X80) (Set = 1, Clear = 0) | Metrology | Attempt to clear. |
| 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. | 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. | Radio Endpoint | Investigate reason for high voltage in field. The alarm will reset when the voltage average window resets. |
| In-Time Sync | N/A (See comments) | In-Time Sync. The endpoint or device's time synchronizes with the tower. | The endpoint or device's time synchronizes with the tower. Status. | Radio Endpoint | No user action is required. This is a status indication only. |
| Leading KVARh | Metrology Leading KVARH | Metrology Leading KVARH. The meter has detected a leading kVAr condition. | Meter has detected a leading kVAr condition. The meter will display CA 040 000. | Metrology | Investigate. |
| Loss of Program | Loss of Program | Loss of Program. | A programming session with the meter did not end correctly. Aclara says the this caution is set when the meter programming session, including set date/time, terminates prematurely. | Metrology | Aclara recommendation is to reprogram the meter. |
| Low Battery Error | Metrology Low Battery | The meter has lost voltage and a battery is not connected or has failed. This causes the meter clock to stop. This warning is expected on meters without a battery. Potential Fail. | Meter lost voltage and a battery is not connected or has failed. Meter will display Er 000 002. Low Loss Potential and/or Low Battery Error bit in Standard Status1 of ST03. | Metrology | Replace the battery and reprogram the meter. If the meter intentionally does not have a battery, the alert should reset after the meter receives a time sync from the FlexNet radio. The alarm resets when the battery has been replaced and the meter powered up and reprogrammed. For a meter purchased without battery, reset with a time sync. |
| 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 | Metrology Measurement Error | Measurement error. | Meter detected a bad voltage reference. | Metrology | Self-correcting. Contact Sensus if the issue persists. |
| Metering Error | Metering error. | Metrology detected a metering error. | Metrology | Investigate. | |
| 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. | The meter could not be read due to no response, bad CRC/Checksum/Parity, or invalid data. | Radio Endpoint | Self-resolving. Replace the meter if the alarm continues repeatedly. |
| Meter Unprogrammed | Metrology Meter Unprogrammed | Meter Unprogrammed. The meter is not programmed currently. | The meter is not currently programmed. Meter will show CA 000 010 on the display. Meter will set the UNPROGRAMMED_FLAG in STD TBL 3 in the meter. | Metrology | Program meter. |
| NONVOL Error | Metrology Non Volatile Memory Error | NVRAM Failure. | Meter has detected an error in stored data and configurations. The kV2c Gen 5 meter continually performs checksum tests on its non-volatile RAM (NVRAM), which consists of EEPROM and flash memory. Each memory type is further segmented according to its use (for example, Load Profile, revenue data, or programming data), and each segment has its own checksum. If a checksum error occurs in any one of the segments, the meter records an NVRAM checksum error. Will display Er 000200. | Metrology | Replace meter. |
| 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 | Investigate service. The alarm will reset when the voltage average window resets. |
| Power Fail - endpoint generated Power Failure - meter generated | 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. 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. | Power Fail - endpoint Power Failure - meter | 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 | Power Fail | Power Restore. AC Power is detected after a power fail. | 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 radio'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 because this field increments each time the power is lost for longer than the Outage Time Threshold. A high value in this field indicates a potential problem only when the unit has not also been reporting a high number of power losses. | Radio Endpoint | The alarm will be cleared automatically when a static setup message is sent. |
| 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 | The alarm will be cleared automatically when a static setup message is sent. |
| RAM Failure | Metrology RAM Failure | RAM Failure. The metrology RAM checksum test failed during bootup. | Indicates a memory addressing error reported by the metrology processor. C1219 ST3 | Metrology | Replace meter. |
| Received KWH | Metrology Received KWH | Received kWh; Energy has been detected coming from the load side of the meter (reverse energy). | Energy has been detected flowing in the reverse direction (load to line). The Demand Overload, Leading kVArh, and Received kWh cautions remain set in the meter until cleared by a manual reset issued from the RNI. | Metrology | Investigate. |
| Reverse Energy | Reverse Energy | Reverse Energy. Reverse power flow has been detected. | If enabled in the meter configuration, the meter sets the meter's ANSI C12.19 Table 3 flag that can be read by the SmartPoint Module indicating reverse energy flow. | Radio Endpoint | Investigate the reason for the alarm. |
| ROM Failure | Metrology ROM Failure | ROM failure. | The meter cannot access the EEPROM. | Metrology | Replace meter recommended by Aclara. |
| 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 does not calibrate. For a receiver that is operating under normal operating temperatures, this field should never be non-zero. | Radio Endpoint | The alarm will be cleared automatically when a static setup message is sent. |
| Single Phase Fail | Single Phase Fail | A single phase outage is defined as one of the power phases reading less than 96 volts. | For a meter form 12S/25S, the module detects phase outages during the periodic voltage monitoring process. When a single phase outage event occurs the module will schedule three alarm messages to be sent with the single phase fail bit set. | Radio Endpoint | 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. |
| Switch Change | Remote Disconnect Switch State Changed | The remote disconnect switch changed state. | When a switch state change occurs the device will send a sequence of messages consisting of 6 each Load Shed ACKs and Alarms. If priority alarms are configured the alarm type is a Short Priority Alarm, Format 11. If priority alarms are not configured the alarm sent is the C&I Alarm. | Radio Endpoint | Investigate the reason for the alarm. |
| System Error | Metrology System Error | System error. | The meter detected an internal hardware failure. Meter will display. Er 000 020. The System Error is triggered when the meter detects a problem with its internal hardware, most likely the microprocessor. This is in the ST 3, Manufacturing Status 1 field. Measurement Error bit (AKA Voltage reference Error) bit in Standard Status 1 are reported as weekly alarm. | Metrology | Replace meter. |
| Tamper | Tamper | Tamper - meter removal. | 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 five 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. |
| Time Changed | Metrology Time Adjusted | Time changed. | Time in the meter has been changed. | Metrology | Monitor. |
| 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 does not lock. For a transmitter that is operating under normal operating temperatures, this field should never be non-zero. | Radio Endpoint | The alarm will be cleared automatically when a static setup message is sent. |
The following eight diagnostics monitor what is happening with the electric service and the load. They report something detected that is out of the ordinary with the service. The diagnostics are constantly monitored by the kV2c meter based on the meter configuration. The diagnostic cautions are reset when the condition clears.
