7.1.1 Faults codes
(continued)
7. Service
Warning faults cover operating conditions where settings or monitored values exceed configured
limits.
Some of the warnings require a manual reset before they are removed from the alarm list.
Faults Alarm description
codes
Warning
5 Low power
6 Flow overflow
7 & 8 Pulse 1 & 2 overflow
9 Consumption warning
L Leakage
(Advanced version
only)
E Empty pipe
C High conductivity
d High flow rate
Note
A reset of the fault log (FT204) also resets all alarms. Once reset, only active alarms become
visible again.

Alarm reasons
Indication of wrong setting or application issues
Battery voltage is below 2 volts or battery capacity is below the low
power % limit (set as customer parameter FT206). When low
voltage is detected, flow measurement and communication will stop,
but the display will remain active as long as some power is
available. The alarm remains active until the fault condition is
resolved.
-> Check the calculated battery capacity (FT510) versus the
battery alarm limit (FT206) and replace batteries as necessary.
Flow rate through the meter is 25% above Qn (Q3) and the meter
stops counting at 125% flow. The alarm remains active until the
fault condition is resolved.
-> Check the sizing of the meter for the current installation.
The pulse rate is higher than the pulse output can deliver.
Reminder: the basic version is limited to 50 Hz maximum; the
advanced version is limited to 100 Hz maximum. The alarm
remains active until the output pulse rate drops below the maxi-
mum pulse rate.
-> Change volume per pulse to a higher value - see section 8
"Technical data" for pulse selection.
The data logged consumption on totalizer 1 has exceed the too low
or too high consumption limit. The alarm remains active until it is
manually reset by FT209.
-> Check data logger values and consumption limit.
The lowest flow rate or volume during leakage period has
exceeded the leakage detection settings. The alarm is active until
it is manually reset by FT208. An alarm reset (similar to leakage
period reset FT820) will reset information for the selected function.
-> Check setting and pipe installation.
The measured electrode impedance is above the empty pipe level
(FT540 & FT541 & FT334). The alarm remains active until the fault
condition is resolved.
-> Make sure the sensor is filled with water.
The electrode impedance is below the low media impedance
(FT542) - meaning the water has a high conductivity. The alarm is
active until the resistance in the water is above the low media
alarm limit.
The flow rate is greater than the flow alarm limit (FT553).
The alarm remains active until the flow rate drops below the flow
alarm limit.
