INTRODUCTION
These operating instructions and description of device functions are provided as part of the
scope of supply. They could be modified without prior notice. The improper use, possible
tampering of the instrument or parts of it and substitutions of any components not original,
renders the warranty automatically void.
The converter is to be used only to be coupled with a sensor to realize a measuring device,
flow meter, that is to be used for measuring the flow of conductive liquids in closed pipes
with conductivity greater than 5µS/cm.
The converter could be coupled directly on the sensor (compact version) or coupled to the
sensor by cable supplied with it (remote version).
The reproduction of this manual and any supplied software is strictly forbidden.
SAFETY INFORMATIONS
Any use other than described in this manual affects the protection provided by the
manufacturer and compromises the safety of people and the entire measuring system and
is, therefore, not permitted.
The manufacturer is not liable for damaged caused by improper or non-designated use.
1) Transport the measuring device to the measuring point in the original packaging. Do
not remove covers or caps until immediately before installation. In case of cartons
packaging it is possible to place one above the other but no more than three cartons.
In case of wooden packaging do not place one above the other.
2) Disposal of this product or parts of it must be carried out according to the local
public or private waste collection service regulations.
3) The converter must only be installed, connected and maintained by qualified and
authorized specialists (e.g. electrical technicians) in full compliance with the
instructions in these Operating Instructions, the applicable norms, legal regulations
and certificates (depending on the application).
4) The specialists must have read and understood these Operating Instructions and
must follow the instructions it contains. The Operating Instructions provide detailed
information about the converter. If you are unclear on anything in these Operating
Instructions, you must call the ISOIL service department.

5) The converter should only be installed after have verified technical data provided in
these operating instructions and on the data plate.
6) Specialists must take care during installation and use personal protective equipment
as provided by any related security plan or risk assessment.
7) Never mount or wire the converter while it is connected to the power supply and
avoid any liquid contact with the instrument’s internal components. To connect
remove the terminals from the terminal block.
8) Before connecting the power supply check the functionality of the safety equipment.
9) Repairs may only be performed if a genuine spare parts kit is available and this
repair work is expressly permitted.
10) For the cleaning of the device use only a damp cloth, and for the
maintenance/repairs contact the service center (for details see the last page).
11) To return the product back for service complete and return the meter with form
found in the last pages of these operating instructions.
Before starting up the equipment please verify the following:
Power supply voltage must correspond to that specified on the data plate
Electric connections must be completed as described
Ground (earth) connections must be completed as specified
Verify periodically (every 3-4 months):
The power supply cables integrity, wiring and other connected electrical parts
The converter housing integrity
The suitable tightness of the sealing elements
The front panel integrity (display and keyboard)
The mechanical fixing of the converter to the pipe or wall stand.
SAFETY CONVENTIONS
DANGER
Warning indicates an action or procedure which, if not performed correctly,
can result in injury or a safety hazard. Comply strictly with the instructions
and proceed with care.
WARNING
Caution indicates an action or procedure which, if not performed correctly, can
result in incorrect operation or destruction of the device. Comply strictly with
the instructions.
NOTES
Note indicates an action or procedure which, if not performed correctly, can
have an indirect effect on operation or trigger an unexpected response on the
part of the device.

ELECTRICAL CONNECTIONS
ALWAYS ensure that the converter and the sensor are grounded (earthed) correctly. The
grounding of the sensor and converter ensures that the equipment and liquid are
equipotential.
Before connecting the power supply, verify that the mains voltage is within the limits
indicated on data plate.
For the connections use only approved conductors, with fire-proof properties, whose
section varies from 0.25mm2to 2.50mm2, based on distance/power; additionally fix
the power supply wires with a additional fastening system located close to the
terminal.
The power supply line must be equipped with an external protection for overload
current (fuse or automatic line breaker).
Provide in close proximity the converter a circuit breaker easily accessible for the
operator and clearly identified; whose symbols must conform to the electrical safety
and local electrical requirements.
Ensure that the component complies with the requirements of the standard for
electrical safety distance.
Check chemical compatibility of materials used in the connection security systems in
order to minimize electrochemical corrosion. In the aluminum housing it should
avoid direct contact between the ground connection cable and the aluminum
housing. It is therefore recommended to connect the safety ground cable, by placing
it between the washer and the metal bracket on the related terminal or use an
eyelet terminal crimped on the ground protection cable.
The sensor, hardwired inputs and outputs are connected to the converter through
terminal blocks located inside the converter.
To locate the terminal block loosen the 4 screws on the front cover. When the front
cover is lifted, the terminal block is visible. The terminal block is the hardwire
connection of the converter to external equipment, including the sensor.
The following pages give informations on the terminal block numbering, and the
respective connecting of the sensor cables, and inputs/outputs.
