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.

Functions in the converter main menu are enabled by the access codes. The information of
this manual is related to all the functions available with the L2 level. All the functions
available through higher level are protected and reserved to the service.

Description of the L2 access code

(menu “11 Internal data” pos. 11.1)

q with code L2 = 00000 (only with this code) you can disable the L2 code request
q * with L2 customized

(freely chosen by the user) you can program all the functions

up to L2 security level, entering the code whenever you need enter the Main menu.

* ATTENTION:

take careful note of the customized code, since

there is no way for the

user to retrieve or reset it if lost.

Factory preset access codes

The converter is delivered with the

default L2 (level 2) access code:

11111

The instrument can 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 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 DESCRIPTION

(description of the functions with access code< 3)

The following pages give a description of the most important functions and how they can be changed or
enabled/disabled by the user.

MENU 1 - SENSOR

(POS. 1.6) Electrodes cleaning [E. cleaning=MIN]

Selectable options: OFF, minimum, average and maximum. It is not recommended the use of this
function (let OFF) when the liquid has a conductivity less than 100µS/cm.

(POS. 1.7) Empty pipe threshold [E.p. thr.=XXX]

This value represents the threshold of measure block to zero in empty pipe condition; the span
function is 20-250. Since the sensibility of empty pipe detection could be changed by the liquid
conductivity, ground connections, type of lining, in case of needed it is possible to adjust manually
the preset threshold. It is recommended to check periodically its proper functioning. Value
increasing means sensibility decreasing.

(POS. 1.8) Autozero calibration [Autozero cal.]

This function activates the zero calibration automatic system. To perform this operation, it is
necessary for the sensor to be full of liquid, and the liquid be perfectly still. Even minimal
movement of the liquid may affect the result, and consequently, the accuracy of the system. Once
you are sure the above conditions have been fulfilled (and the percentage flow rate value is stable)
press the key and automatically activates the zeroing procedure, after which it is necessary to
check that the percentage value showed goes to zero, repeat the operation otherwise. When the
value is stable at zero, then press the key Enter.

MENU 2 - SCALES

(POS. 2.1-2) Full scale n° 1-2 [FS1-2=

dm³/S

X.XXXX]

The full scale is used to indicate to the maximum meter’s flow rate; a volume per time is required.

The full scale should be chosen carefully as it’s parameters are used for several other parameters.
There are four fields to fill in order to set this parameter, from left to right: 1) volume unit of
measure, 2) type of unit, 3) time unit of measure and 4) numeric value. The selection is made by
positioning the cursor on the field to modify. To change the type of unit of measure (metric, British

or American, mass or volume) the cursor has to be positioned on the symbol “/” (field N. 2). When

the nominal diameter is set to zero it is possible to modify only the numeric field, since the unit of
measure stays at m/sec. The following tables show the units of measure available and the
conversion factor by comparison with 1 dm3 and 1 kg. The converter accepts any kind of
co

mbination of units of measure satisfying both the following conditions:

1. Numeric field value

is the maximum full scale value corresponding to the sensor, equal to a 10 m/sec liquid
speed. The units of measure are shown as appear on the display. The British and American units
are diversified by using capital and small characters. Available units of mass and volume:

When a mass unit of measure is set, the specific gravity function is automatically enabled by the
system. The units of measure of time may be chosen among the values: s=second, m=minute,

h=hour, d=day.

(POS. 2.3) Measure unit and number decimal totalizers [MU.tot:dm³X.XXX]

Setting the unit of measure and number of decimals for visualized the totalizers or the volumes to
batch. For set the unit of measure, position the cursor on field of the actual unit of measure; to set
the type of unit, position the cursor on the blank space between the unit of measure and the
numeric value; to set the number of decimal totalizers position the cursor on numeric field and
choose one of the possible combinations: 1000-01.00-001.0-00001.

(POS. 2.4-5) Pulse value output 1-2 and unit of measure of tot. [Imp1-2=

dm³

X.XXXXX]

Setting of the pulse volume corresponding to output 1-2 and of the totalizers measure units. There
are three fields to fill in to set this parameter, from left to right: 1) measure unit, 2) unit type and

3) numeric value. The selection is performed by positioning the cursor on the field to be modified.
To change the unit type (metric, British or American, mass or volume) just position the cursor on
the blank space between the measure unit and the numeric value. When the nominal diameter is
set to zero it is possible to modify only the numeric field since the measure unit stays at meter (m)
or feet (ft). The possible measure units are those above described

(POS. 2.6-7) Pulse duration on output 1-2 [Tpul1-2=msXXXX.XX]

Setting of the duration of the pulse generated on output 1-2. Its value is expressed in milliseconds
and has to be between 0.4 and 9999.99. When the high frequency output is present, then the
minimum value can go down to 0.04 milliseconds.

ATTENTION

: since the instrument cannot detect which type of device it is connected to, it is up to
the user to verify the set pulse duration is compatible with the external device processing such
pulses. If, for example, an electro-mechanical pulse counter is connected, then two kind of
problems may occur: if the pulse is too long than the coil may burn or, if it is too short, the counter
may not be able to count and eventually even cause the damaging of the output itself.

MENU 3 – MEASURE

(POS. 3.2) Measure filter [M. filter=s XXX.X]

This section of the manual is extremely important because the right settings of filters allow to get a
proper meter reaction according to the flow rate behaviour.

WORKING PRINCIPLE

There are two filters:

MFSLN (Measure Filter Slow LeNght): available via ETP and through the display, in menu

3. Measure, function “M. filter”

The M. filter function effects the converter response time while measuring (it is like LOW PASS
filter); the value needs to be chosen carefully as it effects the meter behaviours. A smaller value
with a fluctuating flow will lead to unstable flow readings as the integration filter will be measuring
over very short periods. A higher value corresponds to a more stable but slower measure, a smaller
value gives a faster measure but is more unstable.

MFFLN (Measure Filter Fast LeNght): is available ONLY via ETP

The MFFLN must be set by the user in accordance with the MFSLN (M. filter) to meet the required
meter behaviour.
How the system functions: If the period of flow rate variation is over the MFFLN time (i.e. a slow
flow variation), the outputs (display/4-20mA/Alarms) are refreshed according to MFSLN (M. filter);
as soon as the flow rate variation is within MFFLN time, the output will be set immediately at the
new value.

The combination of MFSLN & MFFLN is useful as it allows the converter to react quickly to large
flow rate variations, regardless of the MFSLN (M. filter) set, therefore delaying (dampening) smaller
fluctuations in flow, resulting in very stable measures.
The value of those parameters has to be within the range from 0 (filter disabled) to the maximum
value defined on below table:

(POS. 3.3) Measure filter AC enable [AC Line fil.=ON/OFF]

This function allow to filter electrical noise on the liquid coming from the main frequency.
(POS. 3.6) Automatic scale change enable [Autorange=ON/OFF]
Enables the automatic change of scale. The meter may have two different working ranges in order
to suit to the variable process conditions. In order to get the best results out of this function it is
important range N.2 is bigger than N.1. When the flow rate increases and reaches the 100% of the
full scale 1, then the meter automatically switches to scale 2. When the flow rate decreases again
reaching a value on scale 2 equal to the 90% of full scale N.1, then the active scale is 1 again.
Allowed values for this parameter: ON/OFF. N.B.: the autorange does not allow using the manual
change of range (pos. 5.6)

MENU 4 - ALARMS

(POS. 4.6) Current output value in case of failure [mA v.fault =% XXX]

Setting of the value the 4-20mA current output has to be in one of the following cases:
empty pipe; coils interrupted; ADC error
The allowed range is from 0 to 120% of the 0-20 mA scale, 120% corresponds to 24mA and does
not depend on the selected range (0-20/4-20mA). The NAMUR NE43 recommendation asks for a
alarms signalling value for the current output lower than 3.6mA (<18%) or bigger than 21mA
(>105%). It would then be preferable to set the value of this function at the 10%, so that the
current value in case of the a.m. cases would be 2mA, allowing the following diagnostics:

1. current < 2 mA - 5%: line interrupted, power supply failure or faulty converter;

2. 2mA -5%

current 2mA + 5%: hardware alarm;

3. 4mA current 20mA: normal working range;

4. 20mA < current 22mA: out of range, measure above 100% f.s.

N.B.: To set this parameter to zero corresponds to disable the alarm
(POS. 4.7) Batch safety timer [Timeout=s XX.X]

With this function is possible to set a maximum time for the batch; over this time will be generate
an alarm.
This function is useful when you need control one or both of the followings condition:

q batch valve open and flow rate is zero
q batch valve closed and flow rate different to zero

When this alarm is activated, they are aborted the batch operation and the power supply of the
valve. The values of function are from 0 to 25.5 seconds and is active only if one or more of the
batch functions are enable.

MENU 5 - INPUTS

(POS. 5.1-2) Modify/reset totalizer enable [T1/2 reset=ON/OFF]

When one of this function is enabled, the related totalizer may be reset through the on/off input.
(POS. 5.5) Autozero calibration external command enable [Calibration=ON/OFF]
When this function is active, applying a voltage on the on/off input terminals the meter performs a
autozero calibration cycle. ATTENTION: if the voltage pulse is less 1 sec., the meter performs a
calibration cycle for compensate possible thermal drifts. If the voltage pulse is more 1 sec, the
meter performs a zero calibration of measure. This function enables/disables the automatic zero
calibration system. To perform the sensor it is absolutely necessary the sensor is full of liquid and
that the liquid is perfectly staying still. Even very small movement of the liquid may affect the result
of this function, and, consequently, the accuracy of the system.

(POS. 9.1) Number of batch samples [N.SAMPLES=XXX]

Number of batch cycles to be done to define the value of compensation. This function allows to
automatically determine the average value for automatic compensation of system delay (pos. 9.3).
Set to ZERO this function for manually introduction of the compensation value.
(POS. 9.2) % limit of compensation [HYST.=%XXX]
This value defines the percentage of maximum difference between the compensation value set
(pos. 9.3) and the average compensation value defined with the function 9.1. Over this threshold
the new compensation value will be automatically set (if number of batch samples is not zero)
(POS. 9.3) Compensation value [V.COM.=XX.XXX]
This value, expressed in the same selected volume unit of measure, is the result of the difference
between the batch value set and the quantity of product really supplied due to the system delays:
closing valves, stop pumps, stop motors, etc. Attention: if you need to set manually the value of
compensation, preset to ZERO the Number of batch samples (pos. 9.1)
(POS. 9.4) Prebatch value [V.PRE.=XX.XXX]
set the volume of liquid at which you want to enable the pre-batch. When the pre-batch volume “V
Pre” is reached the output (if enabled) is de-activated. This value is constant for all quantities to be
batched and must be set in current volume unit of measure. The pre-batch function is useful when
you need fast and accurate fillings.

(POS. 9.5) Enable/disable auto-batch function [AUTO BATCH=ON/OFF]

Applying a voltage on the on/off input terminals for more than 5 second the valve controlled by the
meter stands open while the voltage is applied on the input. When the product has reached the
desired volume/level, removing the voltage from the input, the meter closes the valve and
memorizes the supplied product volume in the current memory batch (see BATCH FUNTIONS); the
value obtained with this procedure will be the volume supplied in every following batch. In order to
modify this value, repeat the operations above. This procedure set the safety timer at a value 1.25
times greater than the time used to reach the batched quantity; after that the counter will be reset.

(POS. 9.6) Automatic selection of batch formula [BM AUTO SEL=ON/OFF]

The function allows the automatic selection of the first 4 formulas depending on the duration of the
pulse of the batch start (see section Input operation stage). This function is active only if the
function cons. mode (pos. 9.7) has not enabled. Besides, activating this function, the automatic
compensation of the batch volume is also excluded (the value of the parameter "N.samples" (pos.

9.1) will be automatically set to zero). However the manual compensation is possible introducing
the opportune value on the parameter "V.com" (pos. 9.3)

(POS. 9.7) Static consent of batch [CONS. MODE=ON/OFF]

The function enable the dosing start and stop using a static signal, instead of an impulsive, applied
to the input (see Digital input section), this signal will have to stand applied all through the batch.
The function automatically disables functions BM AUTO SEL (pos. 9.6) and AUTO BATCH (pos. 9.5).

To

optimize the performances of the meter used as a batch instrument (batch time < 5s), it is
recommended to set it as prompt as possible according to the plant requirements, choosing the
batching setup for the automatic parameter optimization of the quick start menu. It is also
reccomended to disactivate the function 3.3, AC line filter.

ALARMS

Messages ANOMALIES ACTION TO TAKE

NO ALARMS

All works regularly

-----

MAX ALARM

The flow rate is higher than the maximum threshold set

Check the maximum flow rate threshold set and the
process conditions

MIN ALARM

The flow rate is lower than the minimum threshold set

Check the minimum flow rate threshold set and the
process conditions

FLOW RATE >FS

The flow rate is higher than the full scale value set on the
instrument

Check the full scale value set on the instrument and
the process conditions

PULSE/FREQ>FS

The pulse generation output of the device is saturated and cannot
generate the sufficient number of impulses

Set a bigger unit of volume or, if the connected
counting device allows it, reduce the pulse duration
value

EMPTY PIPE

The measuring pipe is empty or the detection system has not
been properly calibrated

Check whether the pipe is empty or perform again
the empty pipe calibration procedure

BATCH ALARM

Batch interrupted for the followings

condition:

q Timer batch expired before the end of the

batch

q Batch valve open and flow rate to zero for a

time longer to the safety timer set

q

batch valve closed and flow rate different from
zero for a time longer to the safety timer set

Verify:

q presetting
q system condition

INPUT NOISY

The measure is strongly effected by external noise or the cable
connected the converter to the sensor is broken

Check the status of the cables connecting the sensor,
the grounding connections of the devices or the
possible presence of noise sources

EXCITATION FAIL

The coils or the cable connecting the sensor are interrupted

Check the connecting cables to the sensor

CURR. LOOP

OPEN

The 0/4...20mA output on board or the optional one are not
correctly closed on a valid load

Verify the load is applied to the output (max 1000
ohm).

To disable the alarm,set the “mA VAL.FAULT” value (

menu alarm ) to 0.

P.SUPPLY FAIL

Power supply different from that suitable in the label.

Verify that the power supply is that suitable on label
