Diehl 500W Water Meter ERT Alarms and Events

ERT has detected an external magnetic field.

500S Cellular devices log the event within 15 seconds of occurrence. To prevent excess events, the tamper interrupt is ignored for 15 minutes after a log entry is created. For the mag event to be logged, the state must change from no mag to detected and it has to be at least 15 minutes from the last mag event.

The endpoint has received a corrupt data character in the Alarm Flags field of the encoded frame from the attached meter.

The endpoint logs this event as soon as it receives the corrupt data character from the meter. The event in the endpoint is not logged again for the remainder of the current day (day ends at midnight UTC endpoint time). This results in a maximum of one of this event being logged per day.

Configured as an alarm by default.

The BPD generates the alarm once every 24 hours starting at midnight UTC.

Corresponds to Err7 in the Diehl meter.

Air in supply system, flow rate measurement not possible.

Configured as an alarm by default.

The BPD generates the alarm once every 24 hours starting at midnight UTC.

Corresponds to Alarm5 (Leak Error) in the Diehl meter.

The Diehl meter activates this alarm once per 24 hours. The meter resets the alarm 15 minutes after the leakage has been cleared.

Corresponds to C-1 (Checksum-Error) in the Diehl meter.

The BPD generates the alarm once every 24 hours starting at midnight UTC.

Electronic error: the meter must be replaced.

Corresponds to Err1 (Temperature Measurement Error) in the Diehl meter.

The BPD generates the alarm once every 24 hours starting at midnight UTC.

Medium temperature too low or too high < 22°F / > 212°F (< - 30 °C / > 100 °C), or cable temperature sensor disconnected or cut off.

Corresponds to Err4 (US-Hardware Error) in the Diehl meter.

The BPD generates the alarm once every 24 hours starting at midnight UTC.

Ultrasonic hardware error, ultrasonic transducer defective or short-circuit, or cable ultrasonic transducers disconnected or cut off.

Corresponds to Err5 (Power Consumption out of limit Error) in the Diehl meter.

The BPD generates the alarm once every 24 hours starting at midnight UTC.

Communication not possible (too frequent reading over optical interface).

Corresponds to ErrH (Overflow Error) in the Diehl meter.

The BPD generates the alarm once every 24 hours starting at midnight UTC.

Corresponds to TMH (Temperature-Hardware Error) in the Diehl meter.

The BPD generates the alarm once every 24 hours starting at midnight UTC.

Corresponds to Alarm1 (Reverse Flow Alarm) in the Diehl meter.

The BPD logs the alarm once every 30 days starting at midnight UTC.

The Diehl meter activates this alarm if the consumption was below the limit configured for the meter. If the alarm has not occurred for 30 days, the meter resets the alarm.

Corresponds to Alarm3 (No Usage Alarm) in the Diehl meter.

The BPD logs the alarm once every 30 days starting at midnight UTC.

The Diehl meter activates this alarm once per 30 days.

The meter resets the alarm as soon as 15 minutes after the issue is resolved.

Corresponds to Alarm4 (Measurement Alarm) in the Diehl meter.

The BPD logs the alarm once every 30 days starting at midnight UTC.

The Diehl meter activates this alarm if both error Err4 and error TMH are active during eight consecutive minutes.

The meter resets the alarm after 30 days if the issue is resolved.

Corresponds to Alarm6 (Low Temperature Alarm) in the Diehl meter.

The BPD logs the alarm once every 30 days starting at midnight UTC.

The Diehl meter activates this alarm if the temperature is less than 3°C after four consecutive temperature measurements (every 16 seconds) and the meter detects Err4 at the same time.

The meter resets the alarm after 30 days if the issue is resolved.

Corresponds to Alarm7 (Empty Pipe Alarm) in the Diehl meter.

The BPD logs the alarm once every 30 days starting at midnight UTC.

The Diehl meter activates this alarm if Err7 is active.

The meter resets the alarm after 30 days without air.

Corresponds to AlarmH (Overflow Alarm) in the Diehl meter.

The BPD logs the alarm once every 30 days starting at midnight UTC.

Corresponds to Alarm9 (End of Life Alarm) in the Diehl meter.

The BPD generates the event only once.

The Diehl meter activates this alarm if the calculated battery life is less than 400 days.

Diehl Hydrus 1.3: Not supported

Diehl Hydrus 2.0: Meter raises this alarm when it detects that the measured medium temperature is greater than 90 degrees Celsius for 60 consecutive minutes. Meter lowers the alarm three days after the measured medium temperature is less than or equal to 90 degrees Celsius for 60 consecutive minutes.

Diehl Hydrus 1.3: Not supported

Diehl Hydrus 2.0: Meter raises this alarm when it detects a significant deviation in the two measuring paths. Alarm is lowered 3 days after the deviation of the two measuring paths goes away. Note that this only applies to the Hydrus 2.0 Bulk (DN50 (2") and bigger) meters.

Diehl Hydrus 1.3: Not supported

Diehl Hydrus 2.0: Meter raises this alarm when an entry is made into the metrological log (only for LAB Role). The meter never lowers this flag. The endpoint should log this event when it sees the meter indicate the alarm, and then only log it again if it sees the meter alarm go away and then reappear.
