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 transmitter is to be used only to be coupled directly 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.
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 transmitter must only be installed, connected, commissioned 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 service. The Operating Instructions provide
detailed information on the transmitter.

5) Repairs may only be performed if a genuine spare parts kit is available and this
repair work is expressly permitted.
6) The transmitter should only be installed after have verified technical data provided in
this operating instructions and on the data plate.
7) Specialists must be carefully during installation and use personal protective
equipment as provided by their security plan about risk assessment.
8) Never mount or wire the transmitter while it is connected to the power supply and
avoid any liquid contact with the instrument internal components.
9) Before connecting the power supply check the safety equipment.
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

ELECTRICAL CONNECTIONS

LWAYS ensure that the transmitter and the sensor are grounded (earthed) correctly.
The grounding of the sensor and transmitter 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 transmitter 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.
The sensor, hardwired inputs and outputs are connected to the transmitter through
terminal blocks located inside the transmitter.
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 transmitter 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.

BLIND CONFIGURATION
For the transmitters without keyboard (blind
configuration), the programming is made
through ISOCON (cable and software needed).
Being the housing closure dependent by the
installer, the IP degree may be compromised, so
follow the torques mentioned.
TRANSMITTER ACCESS
KEYPAD M3
The keypad is accessible by loosening the 4 cover screws and
opening the front cover of the transmitter. Three KEYS are set
aside of the M3 power supply terminal block, allowing the user
to change display visualizations and select functions. Ensure
that the power supply cover is closed.

* The maximum number shown on the totalizer is 999.999.999 regardless of the number of user selected
decimals (see Pos 2.3). Beyond this value the totalizers are set to zero.
Note: The user will see the
screen displayed (left) at
power on of the transmitter.

The ML 110 allows to show a 5 digit character display for flow rate units; this mean the
maximum flow rate value that can be represented on the display is 99999 (no matter the
positioning of the decimal point). The minimum one is 0.0025.
The representable measure unit depends from sensor flow rate and diameter; the
permitted units are those, set the instrument full scale value, allow to be represented with
a numerical field which the maximum value do not exceed 99999.
Example for DN 300:
- Full scale value: 3m/s
-PERMITTED measure unit (example): l/s (216.00); m3/h (777.60); m3/s (0.2160)
-NOT PERMITTED measure unit (example): l/h (777600)..

Functions in the main menu transmitter are enabled by the access codes. The information
of this manual is related to all the functions available with the L2 level. All higher level
functions are reserved for servicing and not available.
Description of the L2 access code
(menu “11 Internal data” pos. 11.1)
with code L2 = 00000 (only with this code) you can disable the L2 code request
*with L2 customized (freely chosen by the user) you can program all the functions
up to L2 security level, entering this code whenever you enter the Main menu.
* ATTENTION: take careful note of the customized code you have chosen, there is no way
for the user to retrieve or reset it if lost.

Functions can be accessed by the keyboard in two different ways:
The Quick start menu makes possible to access directly a range of principal
functions for setting the scale reading and display characteristics of the sensor
Quick start menu can be enabled by function 8.4 (menu display)
Through the Main menu it is possible to access functions with the access code
level 2. These control the sensor’s monitoring, data processing, input/output as
well further display options.
The following example shows how to change the Full scale by Quick Start menu; the
following example illustrates how to change the function by the Main menu.
The transmitter configuration menu can be accessed in two different ways:
1) by ISOCON interface
2) by keyboard of transmitter
Isocon is a Windows®software

transmitter functions and
personalize the menu (IF2X is
required), see suitable manual for
