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

HML 210

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:

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 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.

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.
