8. ERROR REMOVAL AND METER REPAIR PROCEDURES

Error removal and meter repair activities should be reserved to duly qualified staff skilled in maintenance of
electronic equipment and acquainted with the labour safety rules applicable to the plant concerned. On
request, the meter manufacturer will provide training for such staff. The manufacturer's responsibility for any
meter damage due to incorrect handling is precluded.
Prior to any work on the meter such as disconnection or removal of printed circuit boards, sensor
disconnection, dismantling of the display unit, keypad etc., make sure that the supply voltage is
disconnected. At all times, be aware of the danger of electric shock.

8.3. FLOWMETER REPAIR PROCEDURE

Prior to any maintenance or repair action on the internal parts of the meter control unit including the
power source, PC boards, display unit, keypad etc. make sure that the supply voltage is
disconnected.
WARNING: disregarding this instruction implies risk of electric shock.
The meter in the ECONOMIC configuration can be tested using a computer connected to the meter by
means of an USB serial communication line and using the FLOSET program. Alternatively, connect a display
unit and keypad to the FNP5 processor board of the meter to be checked or repaired and carry out the test
as with the COMFORT configuration.
The meter in the COMFORT configuration includes a keypad and display unit. The procedures described in
this manual are focused on identification of a defective board or system component. The serviceman shall
have available replacement boards tested and pre-set by the meter manufacturer. The repair procedure
consists of replacement and checks on the condition of each system component (PC board) in turns. To
exclude the possibility of a defect in the flow sensor, it should be disconnected and a sensor simulator
SF 1.0 put in its place.
