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 directly with a sensor device 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 reproduction of this manual and any supplied software is strictly forbidd

S
AFETY 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 service.

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.
Before starting up the equipment please verify the following:
q Power supply voltage must correspond to that specified on the data plate q Electric connections must be completed as described q Ground (earth) connections must be completed as specified
Verify periodically (every 3-4 months):
q The power supply cables integrity, wiring and other connected electrical parts q The converter housing integrity q The suitable tightness of the sealing elements q The mechanical fixing of the converter to the pipe or wall stand.
SAFETY CONVENTIONS
DANGER
W
arning 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.

GROUNDING INSTRUCTIONS
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.
CONVERTER POWER SUPPLY
q
Before connecting the power supply, verify that the
mains voltage is
within the limits indicated on data
plate.
q ATTENTION:
the converters on dc power supply line
are not protected against the inversions of polarity.
q
For the connections use only approved conductors, with
fire-
proof properties, whose section varies from
0.25mm2 to 2.50mm
2
, based on distance/power;
additionally fix the
power supply wires with a additional
fastening system located close to the terminal.
q
The power supply line must be equipped with an external protection for overload current (fuse or
automatic line breaker).
q 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.
q
Ensure that the component complies with the requirements of the standard for
electrical safety distance.
q Check chemical compatibility of
materials used in the connection security systems in
order to minimize electrochemical corrosion.
q
The sensor, hardwired inputs and outputs are connected to the converter through a
terminal blocks located inside the converter.
q To locate terminal blocks loosen the 2 covers, front and
back. 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.

DIGITAL INPUT
The functions refer to the inputs could be substantially divided in three groups:
1.
only assignable functions to the input 1
2.
functions that act directly on the inputs independently from the select input
3. only assignable functions to the input 2 and only to the input 3 which they
interact between them
Remember that the activation of any functions of batch automatically disable the operation o
f other.
The list of such functions is suitable in the table of the batch
function configuration section.
