INTRODUCTION
These operating instructions and description of device functions are provided for 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, makes the
warranty to decay automatically.
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).
It is forbidden the reproduction of the present manual and of possible software supplied.
SAFETY INFORMATIONS
Any use other than described here 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
package it is possible to place one above the other but no more than three cartons. In
case of wooden package 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.
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 they contain. If you are unclear on anything in these Operating
Instructions, you must call the ISOIL service. The Operating Instructions provide
detailed information on the converter.

5) The converter should only be installed after have verified technical data provided in
this operating instructions and on the data plate.
6) Specialists must be carefully during installation and use personal protective equipment
as provided by their security plan about 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 internal components. To connect remove the
terminals from the terminal block.
8) Before connecting the power supply check 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 deliver the converter back to the service workshop use and fill the form in the last
pages of this 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

ELECTRICAL CONNECTIONS
GROUNDING INSTRUCTIONS
CONVERTER POWER SUPPLY
Compact/separate version
Panel version
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 are 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; as well 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 nearness 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 the materials chemical compatibility used in the connection security systems
in order to minimize the electrochemical corrosion.
The sensor, hardwired inputs and outputs are connected to the converter through a
terminal blocks located inside the converter.
To locate the compact/separate version terminal block loosen the 4 screws on the
back 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.
