9.1 MALFUNCTIONING AND POSSIBLE SOLUTIONS
The following table summarizes the possible malfunctions that may occur during the use of the
MAG converter, for which the possible causes and solutions to be adopted in order to restore correct
operation of the flowmeter are listed.
MALFUNCTIONING
POSSIBLE CAUSE
SOLUTION
The converter shows a flow rate
even when there is no flow.
Grounding missing or incorrect.
Check that the sensor and the
liquid are correctly grounded,
making sure that the relative
earth ground connections are
correctly connected.
Lack of liquid in the sensor
downstream of the converter.
Check that the sensor is full with
liquid.
Electric conductivity of the liquid
is too low or it is not compatible
with the material used for the
sensor electrodes.
Check which electrode type is
used on the sensor.
If necessary, replace electrodes
and/or sensor.
Calibration missing or incorrect.
Perform manual zero calibration
if necessary (Menu - Parameters,
submenu - zero calibration).
MALFUNCTIONING
POSSIBLE CAUSE
SOLUTION
External pulse totalizer shows
results different than expected.
Pulse output configuration error.
Check the conditions in the
paragraph 8.3.4 (pag. 65)
- Menu - Pulse output.
Test the output with the
external flow simulator and the
converter-pulse counter system,
simulating a flow rate through
System > Simulation.
MALFUNCTIONING
POSSIBLE CAUSE
SOLUTION
The screen is turned off and it
doesn’t turn on.
There is no voltage supply or it is
incorrect.
Check the current supply voltage
on the converter plate.
For the battery version, check
the battery life and replace the
battery pack.
