General cleaning of the electrodes
Always refer to the instructions manual of the electrodes.
Wait until no water comes out from the hydraulic system. Disconnect the electrode wires by removing the
respective connectors at their ends and fastening rings and extract them from the probe holders present in the
hydraulic circuit of the control station. Wash the sensitive end with warm water and neutral soap, removing any
grease residues using a soft bristle brush.
To clean the probes, do not rub them with abrasive objects or cloths that can electrostatically charge
them.
If the electrodes are very dirty, they can be cleaned with Denatured Alcohol. On completion of cleaning
operations, reconnect the electrodes with their respective cables and calibrate them without restoring the water
flow to the control station. After calibration operations, electrically disconnect the control station and reassemble
the electrodes in the electrode holder. Restore power supply and the water flow to the control station after having
closed the sampling valve.
Hydraulic system inspection
Visually check the entire hydraulic circuit of the control station after it has been electrically disconnected. In the
presence of liquid leaks, damage to piping or any seal problems, intervene on the hydraulic circuit only after
having stopped the flow of water that reaches the station and having depressurised the system by opening the
sampling valve. Replace the damaged parts only with original spare parts.
Do not leave impurities inside the hydraulic circuit, which can clog it.
Close the sampling valve before restoring the water flow to the station. Gradually restore system
pressure and then power the control station again.
EXTRAORDINARY OPERATIONS IN CASE OF FAILURE
All components supplied by us are chosen and tested according to strict principles of selection and thus
guarantee reliability and operation with our devices for a long time.
Mechanical failures
Since the system is robust, actual mechanical failures do not occur. Liquid can at times leak from a loose fitting
or ring nut, or if the water supply pipe bursts. After eliminating the leak, you must clean and dry the control
station from any water, which, in the event of stagnation, can damage the parts in contact.
THE FLOW INSIDE THE MEASURING CELL IS INSUFFICIENT
•
Check the tightness of the O-rings
•
Check the status of filter clogging;
•
Check the inlet and outlet valves
•
Check the sampling valve.
Electrical faults
NO LIGHT SIGNAL, DISPLAY OFF.
•
Make sure the control station is powered correctly (socket and plug). If the control station remains off,
contact our Assistance Centres.
INCORRECT MEASUREMENTS
•
Carefully check the calibration. If in doubt, reset to bring the instrument back to its default settings.
•
Check correct operation of the probes and their possible wear
