11.4 Fault identification
Make sure to de-energise the meter prior to starting any actions related to fault identification and repair,
such as opening the transmitter housing, checking the power cable connections, disconnecting the
meter sensor or removing PC boards from the transmitter housing.
Nevertheless, some operations require that parts of the meter or its PC boards remain live. In such
cases proceed with utmost care to minimise the risk of electric shock.
Operational/functional tests on the flowmeter can be performed using the RS-485 MODBUS RTU serial
communication line and program FLOSET 4.0.
To carry out any on-site meter repair actions the user will need a set of spare PC boards tested and pre-
set at the manufacturing company. Such repair actions consist of replacement of the defective PC
boards. If the given type of defect is associated with a malfunction of any specific PC board, the user
may try to replace such board upon opening the respective cover of the meter transmitter.
The flowmeter software includes internal control and diagnostic algorithms the purpose of which is to
identify meter defects and show the corresponding error code on the meter display.
Should the error code displayed imply a sensor defect, the sensor can be substituted by the sensor
simulator SF1.0 (applicable to the remote meter version only).

Error description
Likely error cause and error removal procedure
E00
No error
-
E01
AD range overflow
Excessive flow rate (a short-term step change in flow rate from 0 to Q
4
). If
the error condition is of a continuous nature, the fault will be in the measuring
PC board.
E02
Flow-rate step change
See error code E01
E03
Memory read/write error
If RTC time error is too big, replace back-up battery on the processor board.
Should this not help, replace electronic unit (the processor, output and/or
measuring PC boards).
E04
Other types of electronic
unit error
Should the error condition continue, replace electronic unit (the processor,
output and/or measuring PC boards).
E05
Error message in cases
where it is not possible to
calibrate zero flow rate
Wait for a few seconds and repeat zero flow rate calibration. Should the error
condition continue, replace electronic unit (the processor, output and/or
measuring PC board).
E06
Low excitation current
Disconnected excitation circuit
– defective sensor or broken connection
between the transmitter and sensor.
Defective measuring PC board.
Should the error condition continue, replace electronic unit (the processor,
output and/or measuring PC board).
E07
Shorted coil circuit
Short in excitation circuit
– defective sensor or a short circuit in the
connection between the transmitter and sensor.
Check the conditions of signal cables. Replace sensor by sensor simulator
SF1.0.
E08
Information
– zero setting in
progress,
measurement
discontinued
Flow measurement discontinued for one minute. Upon completion of the
zero-setting procedure, this information message disappears from the
display and measurement can continue.
E09
High resistance of
measured fluid
Indication of a not fully-flooded piping condition.
E10
OUT1 output error
Output frequency in excess of 10kHz.
pulse output frequency in excess of 100Hz.
Time period between pulses is shorter than pulse length.
E11
OUT2 output error
See comments to error E09 related to the OUT2 output.
E12
Information on excessive
current
Incorrect configuration of the current output.
Current beyond the range of 4 to 20mA
The output current does not correspond to the flow rate range.
E13
Incorrect time setting
Incorrect time setting following back-up battery replacement.
Should the error condition continue, replace electronic unit (the processor,
output and/or measuring PC board).
E14
Exceeding the value of the
overload flow rate Q4
Check the setting of Q 100%.
Should the error condition continue, replace electronic unit (the processor,
output and/or measuring PC board).
