Siemens 7ME6810, Operating Instructions Manual, Page: 165 / 170

Alarm (parameters 200 to 274)
● Active alarm is indicated on the display
● Monitoring of all alarms with statistic recording on each alarm
– Total hours an alarm has been active
– Numbers of time the alarm has been activated
– First time an alarm appears
– Last time the alarm disappears
● Fatal faults interrupt the measurement, if active
– Signal insulation – Flow signal immunity is influenced (Advanced version only)
– Coil current – Fault in driving magnetic sensor field
– Amplifier – Fault in signal circuit
– Check sum – Fault in calculation or handling of data
● Warning faults
– Low Power – Alarm for customer-selectable battery level or power drop-out
– Flow overflow – Flow in sensor exceeds Qmax (125 % Qn (Q3, Q4))
– Pulse overflow on output A and B – Selected pulse volume is too small compared to
actual flow rate and max. output pulse rate
– Consumption – Saved data logger consumption exceeds customer selected limit on high
or low consumption
– Leakage – Leakage detected based on customer settings (Advanced version only)
– Empty pipe – No water in the pipe/sensor
– Low impedance – Measured electrode impedance below customer low impedance level
– Flow limit – Actual flow exceeds selected high flow limited
Meter status (parameter 120)
Monitoring of important revenue parameters and data
● Changing totalizers 1 and 2
● Changing tariff totalizer
● Changing tariff settings
● Changing date and time
● Alarm has been active (see alarm log for details)
● Fault log has been reset
● Hardware key has been broken
● Meter has been repowered
