This manual is integral part of the product. Read carefully the instructions contained
since they give important indications for the safe use and maintenance.
Technical information and relative products in this manual could undergo modifications
without any previous notice.
The flow meter must be used for what it has been built for. The improper use, possible
tampering of the instrument or parts of it and substitutions of any not original
components, make the warranty to decay automatically.
The manufacturer is considered responsible only if the instrument it’s used in his original
configuration.
Reproduction of the present manual and of any possible software supplied with the
instrument is strictly forbidden.
INTRODUCTION
START UP AND MAINTENANCE OF THE INSTRUMENTS
Before starting up the instrument please verify the following:
Power supply voltage must correspond to that specified in the name plate
Electric connections must be done as described at page 7-8
Ground connections must be done
Verify periodically:
The integrity of the power supply cables, wiring and other electrical parts
connected
The integrity of the instrument’s housing (this must not have bruises or other
damages that may compromises the hermetical sealing)
The tightening of the sealing elements (cable glands, covers, etc.)
The integrity of the front panel (display and keyboard), damages may
compromise the sealing
The mechanical fixing of the instrument on the pipe or on the wall stand

For the correct operation of the meter it’s NECESSARY that sensor and liquid are
equipotential, so ALWAYS connect sensor and converter to the ground
GROUNDING INSTRUCTIONS
CONVERTER POWER SUPPLY
before connecting the power supply, verify that the
mains voltage falls between the limits indicated on
the tag plate
ATTENTION: the converters on dc power supply line
are not protected against the inversions of polarity.
For the wiring use only approved conductors, with
fire-proof properties.
The power supply line must be equipped with an
external protection for current overload (fuse or
automatic line breaker with limiting capacity not
greater than 10 A).
Provide in the proximity of the instrument a circuit
breaker that must be easily accessible from the
operator and clearly identified.
NOTE: characteristics of meter’s power supply, see

PROTECTIONS
The terminals are protected for the accidental polarity inversion; the output is protected
from the extra voltage due to the inductive loads (connections of coils or relay).

HOW WORK THE INPUT
The functions refer to the inputs could be substantially divided in three groups:
1. only assignable functions to the input 1 (page 13)
2. Functions that act directly on the inputs independently from the
select input (page 14)
3. only assignable functions to the input 2 and only to the input 3
which they interact between them (any examples to page 15)
remember that the activation of any functions of batch automatically disable the
operation of other. The list of such functions is suitable in the tab to page 32.

again the input 2 or 3 is been able to
get 2 results:
1) T< 1Sec = restart interrupted
batch
2) T between 1 e 4 Sec = reset

The block of the totalize always determines
the stop of batch. With the function of reset
T2 enable on descent front of input 1 comes
reset the totalize of the batch in course.
therefore the presence of the consent or a
new pulse on the input 2 or 3 they will
determine the start of a new batch
