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.

q For the connections use only approved conductors, with fire-

proof properties, whose

section varies from 0.25mm2 to 2.50mm2, based on distance/power; additionally

fix

the power supply wires with a additional fastening system

located close to the

terminal.

q The powe

r 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.

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.

The sensor, hardwired inputs and outputs are connected to the converter through a

terminal blocks located inside the converter.

q To locate the compact/separate version terminal block loosen t

he 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 information

s on the terminal

block numbering, and the

respective connecting of the sensor cables, and inputs/outputs.

MENU 1-SENSOR

(POS. 1.1) Nominal diameter of sensor [ND= XXXX]

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. 1.8) Electrodes cleaning [El. 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. 1.9) 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. 1.10) 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 long 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 .

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 (Pls1-2, and 3 Measure). 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 1dm3 and 1kg. The converter accepts any k

where fs

max

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

When a measure mass unit is set, the specific gravity function is automatically enabled by the system. Please, note that the mass measure is heavily affected by the temperature. With certain liquids this may cause significant measurement errors. The following measure of time units can be selected: s = second, m = minute, h = hour, d = day.

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

Setting the measure unit and decimals number for visualized totalizers or the volumes to batch. Setting the measure unit and decimals places number displayed for the volumes. To set the measure unit, position the cursor on field of the measure unit. To set the unit type, position the cursor on the blank space between the measure unit and the numeric value; the number decimal places can be selected by placing the cursor on numeric field and choosing one of the possible combinations: 1000-

01.00-001.0-00001.

(POS. 2.4-5) Pulse value channel 1-2 and unit of measure of tot. [Pls1-2=

dm³

X.XXXXX]

This function allows the user to set a signal (a pulse) to be given from the converter when a defined amount of liquid has passed through the sensor. To set the parameter, complete the three fields, from left to right: 1) measure unit, 2) unit type and 3) numeric value. The selection is performed by positioning the cursor in the field to be modified. To change the unit type (metric, British or American, mass or volume) 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 meters (m) or feet (ft). Only those units described above are available to be selected.

(POS. 2.6-7) Pulse duration channel 1-2 [Tpls1-2=msXXXX.XX]

With the liquid volume to generate the pulse value (pos. 2.4-2.5) set by the user. The user must set the corresponding duration of the pulse to be outputed. This 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 type of device is connected to the converter, the user must verify that the set pulse duration is compatible with the external device processing such pulses. If, for example, an electromechanical pulse counter is connected, one of be set to a minimum of 0.04 milliseconds. ATTENTION: since the converter can not detect which two problems may occur; firstly, if the pulse is too long the coils may burn out, secondly, if the pulse is too short, the counter may not be able to function, with the possibility of causing damage of the output.

MENU 3 - MEASURE

(POS. 3.1) Main frequency filter [AC filter=s XX.X]

This function allow to filter electrical noise on the liquid coming from the main frequency. The allowed values are: 0.1s, 0.2s, 1.0s, OFF; 0.1s=ready measure, 0.2s=liquid noise filter, 0.5s=liquid STRONG noise filter.

(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. 3.5) 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 (Fs2) if enabled is bigger than N.1 (Fs1). 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. Note: the autorange does not allow using the manual change of range (pos. 5.8)

(POS. 3.6) Energy saving enable [E.saving=ON/OFF]

Automatic energy saving function enables. This function is used when the instrument is powered by a battery or solar cells, allowing an energy saving up the 60-80%. The energy saving function controls the powering cycles ratio of the coils while the measuring cycling remain unaffected. When the

energy saving function is enabled and the flow rate is stable the number of “off” cycles is greater than the “on” cycles, reducing the average power consumption. If the flow rate suddenly changes,

the meter switches to a higher number of measuring cycles, achieving a higher response time.

To allow this function to work properly set the SMART measure setup (see quick start menu).

MEN

4 - ALARMS

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

The output current signal can be specified by the user in case of failure of either, empty pipe, coils interrupted, or ADC error. The signal current is set as a percentage (0 to 120%) of the 0/4-20mA current. 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 2 mA, allowing the following diagnostics:

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

current 2mA + 5%: hardware alarm;

q 4mA current 20mA: normal working range; q 20mA < current

22mA: out of range, measure above 100% f.s.

Note: To set this parameter to zero disables the alarm (POS. 4.7) Frequency output value in case of failure [Hz V.fault=%XXX]

To set the frequency value assigned to the on/off output in one or more of the following failure cases: q Empty pipe; Coils interrupted ; ADC error Allowable range is from 0 to 125% of the frequency full scale value. Although there are no specific rules regulating cases such as these, it would be convenient to use the failure information as follows: q 0% Hz

frequency 100% f.s.: normal working range;

q 100% f.s. < frequency 110% f.s.: overflow, measure above the 100% of the f.s.; q 115% f.s. frequency 125% f.s.: hardware alarm condition.

(POS. 4.8) 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 following conditions:

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

When this alarm is activate, the batch operation and power supply to the value is halted. The allowed values of function are from 0 (disable) to 25.5 seconds and is active only if one or more of the batch functions are enabled.

When one of this function is enabled, the related totalizer may be reset through the on/off input. (POS. 5.7) “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 than 1 sec., the meter performs a calibration cycle to for compensate possible thermal drifts. If the voltage pulse is more 1 sec, the meter performs a zero calibration measure. This function enables/disables the automatic zero calibration of the system. To perform the calibration it is absolutely necessary for the sensor to be full of liquid and that the liquid is perfectly staying still. Even very small movement of the liquid may affect the result of the calibration, and, consequently, the accuracy of the system.

If the real time clock optional module is present, then the time setting is kept when the converter power supply is off, otherwise the clock is frozen untill the power supply to the converter is resumed. For example, if the power supply has been off for one hour, when switched on the converter will be one hour behind actual time. The calendar is valid till year 2091.

MENU 10 - DIAGNOSTIC

(POS. 10.1) Meter calibration [Calibration]

Enables the calibration of the meter. The activation of this function happens pressing the key during the visualization of the function. The following message will be visualised on the screen: " EXECUTE?" press the key to proceed. Press any other key to delete the operation. (POS. 10.2) Autotest function [Self test] Meter autotest function. This function stops the normal functions of the meter and performs a complete test cycle on the measure input circuits and on the excitation generator. To activate this function, after select it, push key , at the question: “EXECUTE?” push the key for start autotest, or any other key for delete operation. The result of the test is shown on the display. At the end of operation the converter will revert to one of the initial visualization pages. This function is automatically performed when switching on the device. (POS. 10.3) Flow rate simulation [Simulation=ON/OFF] Flow rate simulation enabling. With this function it is possible to generate an internal signal that simulates the flow rate, allowing the outputs and all the connected instruments test. After enabling it, a ‘S’ appears in the top left of the screen and the flow rate simulation can be: q set: by pushing the key from one of visualization pages, to set the required % flow rate

(Fl.rate=%) and the same key to confirm the value;

HML 210

The batch functions allow the user to set the converter to measure a defined volume of fluid and control outputs. An example is opening and closing a value after a predefined volume has passed the sensor. The user sets the volume and the control parameters by the converter through the follwing fuctions (Main menu function group 12 Batch)

MENU 12 - BATCH Menu visualized only with batch active (output on batch and/or pos. 5.9 enable or 5.10 on batch) (POS. 12.1) Number of batch samples [N.samples=XXX]

Number of batch cycles to be completed to define the value of compensation. This function allows the converter to automatically determine the average value for the automatic compensation of the system delay (pos. 12.3). Set the value to ZERO to manually introduce the compensation value. (POS. 12.2) % limit of compensation [Diff.thr=%XXX] This value defines the percentage of maximum difference between the compensation value set (see pos. 12.3) and the average compensation value defined with the function 12.1. Over this threshold the new compensation value will be automatically set (if number of batch samples is different from zero) (POS. 12.3) Compensation value [V.com.=XX.XXX] This value is expressed in the units of measure selected. The compensation value is the difference between the batch value set and the actual system delays due to closing valves, stop pumps, stop motors, etc. To set the compensation value manually, preset to ZERO the number of batch samples (pos. 12.1) (POS. 12.4) Prebatch value [V.pre=XX.XXX] This sets the volume of liquid at which the Pre-batch is enabled. When the pre-batch volume (V.pre) is reached the output (if enabled) is deactivated. 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 dosages.

(POS. 12.5) Enable/disable auto-batch function [Auto batch=ON/OFF]

By applying a voltage to the on/off input terminals for more than 5 second opens the value controlled by the converter. When the required flow volume has passed, the input voltage is removed, closing the value. The converter memorizes the volume supplied in the current batch memory. (see “Batch Functions”). The volume set in this procedure will be the batch volume supplied in every following activation of the batch function. In order to modify this value, repeat the operations described 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. 12.6) 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 page 15 "Operation stage on input 1 or 2"). This function is active only if the function Cons. mode (pos. 12.7) has not enabled (OFF). With the ‘Static consent of batch’, the automatic compensation of the batch volume is excluded (additionally the value of the parameter "N.samples" (pos. 12.1) will be automatically be set to zero). However the manual compensation is possible by inserting an appropriate value on the parameter "V.com" (pos. 12.3)

(POS. 12.7) Static consent of batch [Cons. mode=ON/OFF]

This function enables the start and stop of the batch dosing using a static signal, instead of and

impulse, applied to the input (see page 13 “Digital inputs”), this signal has to be constantly applied throughout the batch. This function automatically disables the functions ‘BM auto sel’ (pos. 12.6) and ‘Auto batch’ (pos. 12.5).

START STOP BATCH

START: it is possible to activate the start of batch in two different ways:

1. From remote input:

assigning the functions of start/stop batch to the input 1 (pos. 5.9)

or input 2 (pos. 5.10) and using the inputs like visualized from page 14.

2. From keyboard: short pressing of the key N.B.: The start of batch from keyboard is always initiated on the release of the key.

The

function is not available with the batch consent (pos. 12.7) function enabled.

STOP: A batch may stop (be stopped) due to three events:

1. Keyboard or remote input (manual stop): short pressing of the key

2. End of batch: In th

is case the batch will be stopped once the batch quantity has been

achieved and a signal given

3. Maximum time of batch:

If a maximum batch time has been set, and is exceeded, the

batch in progress is stopped independently from the batched quantity.

Notes:

during the batch the symbol of the active batch and the name of the formula are

visualized on display.

q When the batch outputs are enabled, pushing the

key for more than 5 seconds will

energize the outputs until the key is released. On the display, I
