Description
Corrupted data in ee‐
prom detected by
checksum test made
during power-up
Battery capacity is be‐
low preset threshold
(default 10%).
Power up (temporary
warning – will disappear
after 4 hours)
125% of Q3
Duty cycle of output A
has exceeded maxi‐
mum possible of 50
Accumulated volume
on totalizer 1 during da‐
ta log period has excee‐
ded the too low or too
high consumption limit
Lowest flow rate or vol‐
ume during leakage pe‐
riod has exceeded leak‐
age detection settings
Measured electrode im‐
pedance has exceeded
the empty-pipe detec‐
tion level (parameters
540, 541 and 334)
Cause
● Power failure during Ee‐
prom write
● Battery capacity low
● Meter has been pow‐
ered up
● Wrong sizing – flow sen‐
sor too small
● Wrong settings for out‐
put A
● Flowrate higher or low‐
er than expected
● Wrong parameter setup
● Leakage in water net‐
work
● Pipe is not filled with
water
Remedy
1. Reset checksum repair alarm via pa‐
rameter 560 and check data.
– All data is checked after operation
(e.g., new flow calculation, writing to
the EEprom, etc.) with a checksum
control. If the checksum result fails,
data will not be considered as valid
and repair data must be made.
2. If data is wrong or checksum error re‐
occurs, replace the PCB board.
The alarm is active until the fault condition
is corrected.
Check calculated battery capacity (param‐
eter 510) versus battery alarm limit (param‐
eter 206) and replace batteries if necessary
Flow measurement and communication
stop, but display remains active as long as
power is available.
The alarm remains active until the fault con‐
dition is resolved.
Check meter sizing for actual installation
Alarm remains active until fault condition is
resolved.
Change volume per pulse to a higher value
- see Technical data (Page 98) for pulse
selection.
Note: Pulse A is limited to 100Hz.
The alarm remains active until output pulse
rate drops below maximum pulse rate.
Check data logger values and consumption
limit.
Alarm remains active until it is manually re‐
set via parameter 209.
Check setting and pipe installation.
Alarm is active until it is manually reset by
parameter 208.
Alarm reset resets information as does
leakage period reset (parameter 820).
Ensure sensor is filled with water.
Alarm remains active until fault condition is
resolved.
