The picture shows how the instrument controls the system adjustment ring.

The MC353 can operate as follows according to its set-up:

FLOW RATE TRANSMITTER

The instrument, thanks to the weight (load cells) and the speed (encoder) signal when it receives the run input, calculates an instantaneous flow rate which is then transmitted externally through a configurable analogue output (0÷10 V, 0÷5 V, 0÷20 mA, 4÷20 mA).

It is also possible to receive the following outputs:

- Weight totalization output;

- Conveyed weight preset output;

- Conveyed weight set output;

- Serial communication protocol, Ethernet included.

- Generic alarm output;

- Flow rate equal to 0 output;

- Conveyed weight reset input;

- USB device communication port;

- Optional USB HOST port with USB pen drive interface.

FLOW RATE CONTROLLER

The MC 353 control unit is configured with P.I. (instantaneous flow rate) regulator; it processes the weight and speed variables to get the instantaneous hourly flow rate and the totalized weight. Furthermore it acts as flow rate self-regulator.

Pag. 7

MC 353 software 1.9

ENG

The external supervisor transmits the work set-up (that can be set also through the keyboard) through the serial communication to the MC353 control unit; the latter, according to the calculated flow rate value, controls directly (through analogue output) the inverter frequency of the motor where the weighing system has been installed.

The MC353 control unit has the following features:

- Weight totalization output;

- Conveyed weight total preset and set output;

- Generic alarm output;

- Flow rate out of tolerance alarm output;

- Flow rate output equal to 0;

- Retroaction analogue output (0÷10V;0÷5V, 0÷20 mA; 4÷20 mA);

- Flow rate proportional optional analogue output;

- Optional analogue input for setting-up the flow rate;

- Inputs for the selection of 15 preset set points;

- Conveyed weight reset input;

- Selection of the instrument state from manual to automatic and vice versa by means of the keyboard, from the instrument rear side through external contact, and by means of serial communication protocol;

- Serial communication protocol, Ethernet included;

- Optional USB HOST port with USB pen drive interface.

1.1 - OTHER FUNCTIONS OF MC353

MASTER-SLAVE OPERATION

This instrument can operate as slave, thus acquiring the flow rate setpoint in continuous duty, through analogue input (0÷10V / 4÷20mA) or digital input (RS485). The flow rate setpoint is updated according to the current input: the flow rate setpoint is divided and it represents the input scale end (100%). In case the current setpoint is set to 0, the setpoint will correspond to the input percentage value of the system maximum flow rate.

The instrument can also operate as master by transmitting the instantaneous flow rate through the optional analogue output or digital transmission (RS485) for the direct connection to instruments in SLAVE operation.

PARAMETERS THAT CAN BE SET

It is possible to set the operation parameters through the touch screen user interface; all parameters are organised on 3 levels with independent access criteria.

All parameters that can be set are listed in a table and clearly identified with a numerical code (address). The parameters reading and writing access is available on the communication port with supervisor (Rs422 / RS485 / Ethernet, optional), through the ModBus RTU protocol. Furthermore the parameters reading and setting can be carried out by sharing files in CSV format on the COM2 communication port (Rs232 or USB) or directly on USB pen drive connected to the USB Host port (optional).

For operation details see the relevant paragraphs.

DATA IMPORT / EXPORT

To facilitate the data set-up and acquisition in a format that can be used with standard informatic systems the instrument is provided with files transfer functions (TXT or CSV). It features especially a reading/ writing (even partial) of the memory parameters from CSV files and a data logger procedure to acquire operation parameters.

To customise the instrument it is possible to set the setpoint names, create Help pages and load the image displayed upon switching-on (BMP file).

If the instrument is provided with a USB Host option, the import and export of the files mentioned above can occur directly on USB pen drive.

2.2 - INSTRUCTIONS FOR A CORRECT INSTALLATION OF THE LOAD CELLS AND THE MICROPROCESSOR SYSTEMS

1. Do not carry out weldings with load cells fitted.

2. Use a copper conductor to connect the load upper support plate with the lower one, then connect

both upper plates with the earth line.

3. Use watertight fittings and sheaths to protect the cells wires.

4. Use a watertight connection box and a terminal board with cable clamp to connect the cells in

parallel.

5. All “shielded” cables for signal amplifiers or cells connection extensions shall be inserted alone in

the cable conduit or in a tube as far away as possible from the power cables.

6. The amplifier or cells cable shall be inserted in the panel from one side or the other and it should be

connected directly to the instrument terminal block without being interrupted by additional terminal blocks or passing through cable conduits with other wires.

7. Use “RC” filters on the coils of remote control switches and the solenoid valves controlled by the

micro-processor.

8. In case of condensate inside the equipment it is recommended to always keep them powered.

9. The electric panel installer shall provide all instrument electric protections (fuses, door lock switch,

etc.).

10. It is recommended to connect the housing of the instrument to the protective earth (possibility to use

the set screws of the control unit).

2.3 - ELECTRIC CONNECTIONS

Only qualified personnel shall carry out the procedures described below. All connections shall be made with instrument OFF.

- The cell cable shall not be inserted together with other cables (for eg. outputs connected with remote control switches or supply cables), it must be routed in its own path.

- Any cable extension connection shall be carefully shielded, respecting the colour code and using the cable type supplied by the manufacturer. The extension connections shall be made through welding or support terminal blocks or connection box supplied as optional.

- The cell cable shall have a number of conductors not higher than those used (4 or 6). In case of a 4-conductors cable connect the reference wires by making a jumper across the relevant poles of the supply cables.

It is possible to connect up to maximum 8 350 Ohm cells in parallel to the instrument. The cells supply voltage is of 5 Vdc and is protected against temporary short circuit. The instrument measurement field foresees the use of load cells with sensitivity from 1 mV/V to 5 mV/V.

IN1 - Run static input. Close this contact to enable instrument begin and maintain programmed operations (weighing, flow regulation, alarms etc.). Input must be kept closed during dosing; open the contact to stop operations.

IN2 - Manual selection (open) / automatic (closed). The selection through the keyboard has the priority over the selection of this input. When a selection that does not correspond to the input state is changed through the keyboard, to commutate the selection with this input it is necessary to first set the selection according to what had been done by the keyboard, and then commutate it in the desired position. For example: with the input set to AUTO, it is possible to commutate it to MAN through the keyboard. To restore the automatic operation using the input it is necessary to first set the input to MAN and then to AUTO.

IN3 - Bit 1 setpoint selection with BCD coding. The selection is shown on the display. When all inputs are open the system keeps the last selected combination (even if you switch off the instrument).

IN4 - Bit 2 setpoint selection with BCD coding. The selection is shown on the display. When all inputs are open the system keeps the last selected combination (even if you switch off the instrument).

IN5 - The function of this input can be selected: the input (closed by pulses) can control the belt homing remote procedure. Otherwise you can have the function combined with inputs 3, 4 and 6 for selecting the setpoint with BCD coding. (inp. 5 = bit 4). To start AUTOZERO procedure, close input 1027 (parameter INPUT FUNCTION 5 = “belt reset mode”); the above procedure can be activated only when 3028 RUN STATUS is STOP. Then, set 3028 RUN STATUS = RUN and keep it that way during the whole duration of the procedure. The duration of the procedure depends upon the time settings of parameter 0132 BELT LAP TIME, so please wait until this time elapse. During this period, if there are any anomalies, will be indicated by the alarm output. If, during AUTOZERO procedure duration, no alarm is raised, you can safely assume that the procedure has successfully ended. Now you can set again 3028 RUN STATUS = STOP.

IN6 - The function of this input can be selected: the input (closed by pulses) can control the conveyed total reset, with receipt print if the printer is suitably set. Otherwise you can have the function combined with inputs 3, 4 and 5 for selecting the setpoint with BCD coding. (inp. 6 = bit 8 if inp. 5 = bit 4; inp. 6 = bit 4 if inp. 5 is selected to control the belt homing procedure).

NOTE: inputs are activated only if activation time exceeds 500 msec.

OUT1 - Total Set reached. This output is active when the total conveyed product exceeds the set value, anticipated of the set flying material. If the set value is zero, this output is never excited.

The output is disabled when the total conveyed product is reset.

OUT2 - Total PreSet reached. This output is active when the total conveyed product exceeds the SET value - PRESET value. If the set value is zero, this output is never excited. The output is disabled when the total conveyed product exceeds the SET value - PRESET value. If the set value is zero this output is not excited. The output is disabled when the total conveyed product is reset.

OUT3 - Totalization pulse. This output is excited by pulses (0.5 sec.) each time that the quantity of product that is conveyed is equal to the set value, max. 1 impulse per second (1 Hz)

OUT4 - Functioning alarm. This output is activated when at least one of the scheduled alarms occurs (except alarm 3). You can program this function. OUT4 is deactivated automatically when function is one again normal. Output is active during RUN or always according to parameter’s 1030 settings.

OUT 5 - Instantaneous flow rate out of tolerance. During belt’s RUN (only in automatic mode), this output is active if instantaneous flow rate exceeds the set limit. OUT5 is deactivated automatically when function is one again normal, i.e when flow rate is within tolerance. You can program this function.

OUT6 - Null flow rate alarm (Al 3). During the belt movement this output is active when the null flow rate alarm (minimum weight or encoder signal missing) is triggered according to the conditions defined by the 1022 parameter selections.

Data bus transmission on RS485 / RS422 connection is differential type, i.e. signal is the result of tension difference between the 2 wires composing the bus.RS485 / RS422 transmitters provide an output (under load) of ±2-3 V between output A and B; receivers recognize output levels up to ±200 mV as a valid signal.

This technique provides excellent disturb immunity even with long cable runs. To minimize reflections, transmitter must have the possibility to insert the polarizing resistance while first

and last network line element should be equipped with a terminal line resistor, connected inparallel to the line.

Typically, terminal line resistors must have resistance values between 120 and 560 ohm.

In case of connections with double pairs RS422 and two nodes, resistances should be near the further receiver while value can be low up to 120 Ohm (see figure)

COMMUNICATION PORTS SUMMARY

The instrument is equipped with three independent communication ports: COM1, COM2, COM3. COM1 has 2 possible interfaces (that can be used alternatively): RS422/RS485, Ethernet or Profibus

(optional). COM2 has 3 interfaces (that can be used alternatively): RS232, USB device, RS485. COM3 has an RS232 interface with only transmission functions and CTS management. Following is a diagram with all possible connections:

- operation display

- ﬁrmware update

(optional)

MC353 MASTER / SLAVE

In case of connections with double pairs RS422 and more nodes, same 120 Ohm value is indicated at the figure, but this is valid for very long lines (hundreds of meter). If line is considerably shorter, resistance value must raise because impendence at 120 Ohm would be very low, 60 Ohm (not counting the receivers load). It would be better to use resistances in the ~250 Ohm range.

Same considerations apply to the RS485 connection. Use 250 Ohm resistances for lines not very long.

MAIN ANALOGUE OUTPUT (CONTACTS 12÷14, UPPER TERMINAL BLOCk)

The instrument is provided with a current and a voltage analogue output.

Features:

- Voltage analogue output: range from 0 to 10 Volts or from 0 to 5 Volts, minimum load 10KOhm;

- Current analogue output: range from 0 to 20 mA or from 4 to 20 mA. The maximum load is 300Ohm. For the connection use a shielded cable having care to connect to earth the screen to only one of the

two sides. The analogue transmission is particularly sensitive to the electromagnetic interferences and thus we

recommend that the cables are as short as possible and that they follow an independent path.

OPTIONAL ANALOGUE INPUT (CONTACTS 18÷-19, UPPER TERMINAL BLOCk)

It is possible to have an analogue input as optional with measurement field 0÷5V, 0÷10V, 0÷20mA, or 4÷20 mA. The measurement field shall be chosen during the order stage and can not be selected by the instrument.

The ADC has a 24 bit resolution.

NUM.

(pitch 5.08 mm)

ENCODER INPUT (CONTACTS 20÷23, UPPER TERMINAL BLOCk)

Connection for 2-phase encoder with 24 Vdc power supply.

- The encoder cable shall not be inserted together with other cables (for eg. outputs connected with

remote control switches or supply cables), it must be routed in its own path.

- Any cable extension connection shall be carefully shielded, respecting the colour code and using the

cable type supplied by the manufacturer. The extension connections shall be made through welding or support terminal blocks.

The maximum frequency of the encoder signals acquisition is of 2 KHz. Fit the encoder so as to avoid exceeding such work frequency. Example: if the encoder resolution is of 10000 pulses / rev. the rotation speed shall not exceed 12 rpm.

The encoder acquisition is of the up-down type (counting in both rotation senses). For this reason both phase cables (A and B). The rotation sense is automatically detected by the instrument.

- The RJ45 ethernet connection cable has a variable length which depends on the cable type. One Cat5 standard shielded cable can have a maximum length of nearly 180 m.

- It is possible to connect the ethernet communication port directly to the PC without passing through other network devices (routers, switches, hubs, lan-bridges or other), but it is necessary to use special RJ45 cables called “crossover”.

- Usually cables are of the “direct” type, and they allow a connection to network devices such as routers or hubs, but not to directly connect the two PCs (even if currently there are network boards with auto-sensing technology that recognise the cable and the connection type thus allowing PC-PC direct connections even without using crossover cables).

- Following are the diagrams of the two mentioned cable types and the relevant connection diagram.

- The cable shall not be inserted together with other cables (for eg. outputs connected with remote control switches or supply cables), it must be possibly routed in its own path.

TECHNICAL NOTES ABOUT THE BELT SPECIFICATIONS

TECHNICAL NOTE: MAXIMUM HOURLY FLOW RATE The set-up of this value determines also the indicated hourly flow rate resolution even though the instru-

ment uses a resolution 10 times higher. The unit of measurement of the hourly flow rate can be deduced from the following table.

The maximum hourly value is also used as analogue output scale end, both the adjustment one and the optional one for the transmission. Such value can be adjusted with the MACHINE TEST procedure.

Max.

ow rate

Flow rate

resolution

Weigh re-

solution

The instrument does not accept maximum hourly flow rate values that determine a ratio with the load cells unit of measurement lower than 20 or higher than 50000.

TECHNICAL NOTE: LOAD CELL FLOw RATE

The setting up of this value determines also the weight unit of measurement that can be deduced by the following table.

The load cells flow rate value, together with the set sensitivity, is processed to get the weight theoretic adjustment, which is calculated again at the menu output when one of these two parameters has been modified.

The side table indicates the units of measurement calculated by the system according to the installed

load cells max. ow rate. More in detail the rst square

shows the total cells load, whereas in the lower part is indicated the relative unit of measurement (value in kg).

The instrument does not accept values of the load cells flow rate that determine a ratio between a max. hourly flow rate and load cells unit of measurement lower than 20 or higher than 50000.

The total setpoint output control can not be connected with the general total. For both totalizers the max value that can be counted is 99999999 (8 digits), and after this value it is

reset. For both totalizers the weight resolution can be selected between 10x and 100x with respect to the weight unit used for the hourly flow rate.

TECHNICAL NOTES: GENERAL TOTAL

The general total counts the conveyed total weight separately from the standard total (lower level). The reset of such values is independent.

DR/2

TECHNICAL NOTE: ENCODER ACqUISITION

The encoder acquisition occurs in 2 phases (A and B), with rotation sense control. The phases connection does not matter since the instrument detects the prevailing rotation sense.

The encoder nominal resolution can be increased (2x or 4x) according to the phases acquisition modes, as shown in the following pictures:

C : 1x P : 2x S : 4x

DR corresponds to the distance between weighing bridge upstream and downstream rollers.

WEIGHING WITH BELT ON LOAD CELLS

WEIGHING WITH OVERHANG BELT

DR corresponds to the distance between the material load and unload point multiplied by two.

WEIGHING ON BELT

DR=(A/B)xA where A is the distance between the belt fulcrum and the material unload point, whereas B is the distance between fulcrum and load cell.

The rollers distance (DR) is measured in different ways according to the type of belt the weighing bridge is installed on. The following picture shows a summary of the different types with relevant identification mode of the parameter.

TECHNICAL NOTE: ROLLERS DISTANCE

TECHNICAL NOTE: BELT INCLINATION

The set-up of this value affects the saved weight adjustment by compensating the load cells response. It is possible to set the inclination degree after having adjusted the belt in horizontal position (or having carried out the theoretic adjustment), or proceed with the sample weight adjustment after having set the inclination degree.

The detected weight is calculated according to the belt inclination:

COMPENSATED WEIGHT = DETECTED WEIGHT / COS (angle)

TECHNICAL NOTES ABOUT THE SYSTEM SET-UP

This selection enables the flow rate setpoint continuous change function by one master. According to the selected value, this change can occur through COM2 (RS485) serial line or through analogue input. In the latter case the instrument must be provided with an analogue input optional board. The set flow rate setpoint value corresponds to the master input scale end (digital 1000 value or analogue input scale end) and is modified in proportion to the input.

TECHNICAL NOTE: MASTER INPUT

TECHNICAL NOTE: USB HOST PORT

The activation of the USB Host port implies the presence inside the instrument of the optional board which allows to interface one USB pen drive for saving and loading files. When this function is active the LOAD set-up, SAVE set-up and LOAD FILES operations are automatically addressed to this port and are no longer available on the COM2 line. The DATA LOGGER operation is, on the contrary, selectable between the 2 communication ports.

TECHNICAL NOTE: OTHER SELECTIONS

The other set-up menu selections must meet some compatibility requirements, otherwise upon the parameters menu output the display shows the error page. The requirements are as follows:

When selecting Operative Function = TRANSMITTER you must have 2nd Analogue Output = NO. When selecting Operative Function = TRANSMITTER you must have Master Input = NO. When selecting Master Input = ANALOGUE you must have Master Input = YES

The “TOTALIZATION” selection indicates the total setpoint use, and relevant parameters with set and total preset outputs management.

TECHNICAL NOTE: 2

ANALOGUE OUTPUT

The activation of the second analogue output implies the application of the optional board in the instrument.

In this configuration, during the run the second analogue output is in proportion to the current hourly flow rate and its scale end is the system maximum flow rate.

TECHNICAL NOTES: OPERATIVE TIMES

- Stop delay: the time at the end of the run, (input 1 opening) when the instrument continues totalizing the product even if it does not adjust the flow rate.

- Weight timeout: maximum time in which the weight during the belt movement can keep the same value before triggering the relevant alarm.

- Adjustment delay: delay, with respect to the run start, during which the instrument does not adjust the flow rate and keeps the starting output value.

- Tolerance delay: flow rate tolerance alarm activation delay. The alarm is activated only after that the flow rate remains out of tolerance for at least this time.

- Start tolerance delay: delay, with respect to the run start, during which the instrument does not control the instantaneous flow rate tolerance.

USER MENU TECHNICAL NOTES

TECHNICAL NOTES: VARIABLE FILTERS

- Minimum weight: under this threshold the flow rate is considered null.

- Minimum analogue output: below this analogue output minimum percentage value it is not possible to start the belt.

3.6 - LIST OF PARAMETERS PRIOR TO COMMISSIONING

For correct working conditions of the weighing system, the main parameters to check and enter before start are explained.

Par. Name Description Value

Maximum ﬂow rate of the system expressed in Kg/h. Programming of this parameter

determines the scale and ﬂow rate unit of measurement (see page 37), the same

value corresponds also to the Scale End analogical output exit in case it works as a

TRANSMITTER.

Sum of the system load cells ﬂow rate.

E.g..: if there are 2 load cells with nominal ﬂow rate of 50 Kg, set 100.

Programming this parameter also determines the weight unit of measurement (see page

37).

Number of revolution pulses of the encoder.

Refer to encoder ratings (normally 1000 Pulses/Rev)

Parameter visible only if 0012=YES.

Through this parameter it is possible to increase the encoder resolution X1, X2, X4 (see

technical note).

Generally use X1, in case of very slow belts use X2 or bigger.

Measure in cm to detect on the weighing system.

Since the method to measure this distance varies depending on the type of weighing belt,

refer to the diagram on page 38 on how to obtain the correct measurement.

Inclination of weighing belt (Max. 30°). Programming this parameter acts on the weight

setting in the memory ,compensating the load cells response. The weight is calculated

according to the belt inclination:

CALCULATED WEIGHT = DETECTED WEIGHT/COs (angle)

Sensitivity of load cells expressed in mV/V .

Refer to cells ratings (normally 2 mV/V).

Belt speed expressed in m/min .

The parameter is visible and must be set only if the encoder is not present (parameter

0012=NO).

The totalizator resolution can be increased with regards to the hour ﬂow rate resolution

10X or 100X.

Regulation parameter (not visible in case of TRANSMITTER). It is the ratio between instant

ﬂow rate variation and speed regulation analogical signal variation.

Regulation parameter, speed signal correction intervenes each time it reaches the set

number of samples in this constant.

E.g..: If Sampling Time= 3 seconds Integral Const.= 2 corrections will take place every 6

seconds.

Non intervention regulation belt (expressed based in the selected unit in N°0163).

Regulation does not intervene if the instantaneous ﬂow rate detected is between the range

Set Point Dead Belt and Set Point + Dead Belt.

Parameter which determines the activation of the out of tolerance alarm OUT 5.

If detected instantaneous ﬂow rate diverges from the one set in the Set-Point by a value

higher than the one set in the constant, the relative alarm is activated.

Totalization pulse, each time the total weight reaches a multiple of the value set in this

constant, the relative output OUT 3 is activated.

Selects the activation mode of the Null ﬂow rate output alarm (OUT 6) between:

NULL FLOW RATE= output is activated if during the run there is no ﬂow rate detected due

to weight = 0 (product missing) or speed = 0 (absence of encoder pulses);

MIN. WEIGHT=output is activated if during the run there is speed >0 (encoder pulses

present) detected weight is under the minimum values.

The logic of output alarms OUT 4 and OUT 5 can be selected between NO (normally

opened) and NC (normally closed).

In case of NC output is raised only after having closed the RUN input (IN 9).

Impossible regulation can be included or excluded from the general alarm activation causes

(OUT 4) through this parameter.

Possible absence of encoder pulses during run (IN RUN active) can be included or exclu-

ded from the general alarm activation causes (OUT 4) through this parameter.

Multifunction Input can be selected between:

Set Point selection or Belt Homing procedure activation.

Multifunction Input can be selected between:

Set Point or Totalizator and Print control reset selection (if present).

Time activated after opening of input RUN (IN 9) during which the instrument continues to

4.1 - INSTRUMENT COMMISSIONING PROCEDURE

For correct working conditions of the instrument, keep to the following steps. Only qualified personnel shall carry out the procedures described below.

1. Install the instrument and connect the terminal boards as shown in the diagram in the manual.

2. Only after being certain of the cabling made, supply power to the instrument and verify INPUT / OUTPUT using also the TEST FUNCTIONS. Check also weight and speed readings. Weight value shall be positive and shall increase when some

pressure is exerted onto the weighing bridge, while speed value shall correspond to the belt speed and vary proportionally.

3. Parameter the instrument according to installation specifications, usually it is not necessary to access SET-UP MENU parameters since it has already been configured as requested by the customer.

However, it is necessary to set the following parameter groups in the TECHNICAL MENU:

- Belt Specifications;

- Communication ports.

and in the USER MENU:

- Select I/O.

4. Perform a SYSTEM CALIBRATION after DYNAMIC BELT HOMING following the DYNAMIC BELT CALIBRATION.

Only if it is not possible to make a test with the product, perform the WEIGHT SAMPLE TEST CALIBRATION.

5. Start the system and adjust “operating” parameters:

- Adjustment Parameters;

- Operative Times;

- Variable Filters.

4.4 - MACHINE TEST PROCEDURE

Through this procedure it is possible to define one precise correspondence between the flow rate and the speed adjustment analogue output signal.

In correspondence to a speed value within 20% and 80% it is possible to save the real flow rate value; this allows to assume already from the first start the speed value corresponding to the required setpoint and to speed up the adjustment.

This procedure is not compulsory because usually the maximum speed is associated with the value saved in the Maximum Flow Rate and shall not be performed if the instrument is set as Transmitter.

During the test no adjustment is carried out and the I/O are not managed. It is furthermore necessary to make sure that the passing product is constant and that the working conditions are the standard ones.

Set the speed value in manual mode (20% ÷ 80%).

Start the belt and make sure the product is constant.

After saving the current hourly flow rate the display shows the value corresponding to the calculated scale end and the previous value.

With output within 20% and 80% this key allows you to save the

detected ow rate, to calculate the real ow rate at scale end

according to a linear proportion.

It rejects the calculated value and restores the old one.

It conrms the new calculated ow rate scale end.

5.1 - BELT HOMING DYNAMIC PROCEDURE

This procedure allows to reset the weighing system tare with moving belt.

The procedure duration is determined by the time/ length values set in the relevant parameter (we recommend a value corresponding to one complete cycle).

At the end of the procedure the zero calibration is automatically saved by considering the mean of all sampled weights.

During the zero calibration stage the belt must move empty (without product).

The weighing belt calibration is a fundamental stage to get a correct measure and shall always be carried out; it is furthermore necessary to repeat it periodically and each time you carry out mechanical adjustments on the belt.

The calibration consists of two phases:

1) Zero calibration that allows to acquire the system tare and can be carried out both with moving belt (recommended procedure) and with stopped belt;

2) scale end calibration that can be carried out both with a product (recommended procedure) and with a sample weight.

Note: before proceeding with the calibration make sure to have correctly set the flow rate parameters of cells, sensitivity, maximum flow rate and belt inclination (parameters 0154, 0160, 0152, 0159).

Press the PROG key to enter the set-up menu and enter the values corresponding to one complete cycle of the belt through the parameters (operative mode, cycle time or length).

Note: this operation shall be carried out only the first time since the parameters remain in memory.

Only in case the instrument is set as regulator you shall set the speed at which you want to carry out the test by means of the special control.

Check that the belt is completely empty.

It starts the weight reset procedure; to do this you will be asked to enter a password (if set).

Once the reset procedure is started the system waits for the run input closure and, when it detects the belt movement through the encoder, it measures the belt cycle time or length. The measure that remains at the end of the procedure is displayed as decreasing in the state section. It is possible to interrupt at any time the procedure by the touch screen without modifying the weight calibration. At the end of the reset tare value is displayed in the relevant menu of the parameters.

It quits the procedure and goes back to the technical menu.

5.2 - BELT CALIBRATION DYNAMIC PROCEDURE

TECHNICAL MENU -> SYSTEM CALIBRATION-> BELT CALIBRATION

This procedure calibrates the belt with product by getting a K correction factor.

During the test a certain quantity of product is conveyed on the belt (the product could be recovered at outfeed and weighed on the static balance) and the correspondence between real and calculated weight is checked.

The K factor is calculated by the instrument as a ratio between the total weight calculated by the same and the one actually conveyed detected and set by the operator.

Before starting the test, reset all values by pressing the relevant section.

Only in case the instrument is set as regulator you shall set the speed at which you want to carry out the test.

Start the belt by closing the run input and pass the quantity of product necessary for the test and then stop the belt.

It enters the real conveyed weight set-up in case the value does not correspond to the one calculated by the instrument.

After setting up the detected real weight the display shows the calculated K correction

factor and the previous value.

It confirms the correction value.

It rejects the value and restores the previous one.

The reset procedure can also be activated by a remote control using the saved parameters only in stop conditions. The control can be transmitted by the serial line (5001 parameter), or by the logic input (input 5). The procedure modes are the same of the manual one but with set maximum resettable value (0135); at the end the general window is restored.

5.3 - ZERO STATIC CALIBRATION AND WITH SAMPLE WEIGHT

TECHNICAL MENU -> SYSTEM CALIBRATION -> WEIGHT CALIBRATION

Note: during the calibration test it is necessary to follow the rule below: if you start with empty belt you must finish with empty belt, if you start with full belt you must finish with

full belt.

This procedure shall be used in case it is not possible to carry out the reset with moving belt or the calibration of belt with product.

The detected weight is first of all determined by the nominal flow rate parameters and the cell sensitivity (parameters 0154 and 0160); furthermore the calibration is influenced by the belt inclination (parameter 0159).

ZERO CALIBRATION

CALIBRATION wITH SAMPLE wEIGHT OR CHAINS

With this key you start the ZERO CALIBRATION; make sure that the belt is empty (without product) and the weight is stable, then press the key to save the detected value as system tare.

Once the zero value has been saved it is possible to check/calibrate the system by using one sample weight (knowing its total weight) or chains (knowing the weight per meter).

For this procedure it is necessary to put the weight or the chains in the weighing area and check the weight displayed on the instrument. In case of significant differences proceed with the calibration.

CORRECTION FACTOR MANUAL CALCULATION AND SET-UP

This function allows to manually set the “correction factor”; this is useful when you have production data and you wish to correct the calibration without carrying out a specific test.

The new correction factor (K) shall be calculated as follows:

K = K1 x REAL TOTAL / CALCULATED TOTAL

Where : CALCULATED TOTAL = value of calculated weight displayed by the instrument REAL TOTAL = value of weight actually conveyed on the belt K1 = correction factor saved in the instrument during the test

In page 2 of the belt calibration window it is possible to see the saved K factor and to enter directly the set-up of the previous calculated value by pressing the relevant section.

If enabled, it will be programmed in sequence the KK factor.

5.4 - MC 353 OPERATION ALARMS

During RUN the following alarms may occur, shown in the display’s dedicated area, up to the right, with a blinking icon, beyond the activation of the relevant output. All alarms deactivate automatically when the cause ceases to exist and normal function is established, but blinking icon still stays on until manual RESET occurs (press the dedicated virtual button) or until the next RUN START (except out-of-tolerance alarm which ceases automatically by itself). The alarms linked with an external input module are active if each input is associated with an alphanumeric description (they have low priority; among them the highest priority goes to input 1 on module 1 while the least goes to input 4 on module 2).

With this key you enter the sample weight loaded on the belt (in Kg/m) usually made up of chains placed on the whole weighing area whose weight per meter is known.

OR It allows to enter the sample weight loaded on the belt (in Kg); usually one roller placed near

the load cells axis.

5.5 - DENSITY CALIBRATION PROCEDURE

Density calibration consist in programming parameter Specific Weight and register a weight value for “Peso Mem”. These values are used for actual density calculation according the formula indicated at the next chapter.

Press box on display to setup the specific weight

Press box on display to setup the actual weight

DENSITY CALCULATION

Density parameter is calculated according the actual weight detection, based upon the following formula:

WEIGHTmem : PS = actualWEIGHT : D Where:

- WEIGHTmem: calibration weight value recorded during density calibration phase;

- PS: specific weight;

- actualWEIGHT: actual detected weight;

- D: calculated density.

Density is transmitted to the 3rd analogue output (*). To enable data transmission, set, through “SYSTEM SETUP” the parameter “3rd ANALOGUE OUTPUT” = YES. Also, set parameter “FS DENSITY” at the value you wish to associate to the upper limit of the analogue output.

Density, specific weigh and full scale density are expressed in kg/dm3 units with 3 decimals and upper value 2000 kg/dm3 (*) 3rd analogue output is a serial data transmission to a D/A converter (code SW P12043) which receives digital data to convert to analogue output (tension or current depending upon D/A converter’s configuration). Further details on the specific manual.

Serial transmission is held on COM3 (parameters 9600, N81, frequency 5Hz). Transmitted string:

<value> 5 numeric digits for density, related to the full scale according the formula: Density : FSdensity = <value> / 10000

When the 3

analogue output is active, parameter “protocollo COM3” is forced to NUL

6.1 - DATA LOGGER

6 - aDDITIonal fUncTIons of Mc 353

This function can be enabled by the technical menu and allows to continuously record run operative data to analyse the system behaviour over time. The provided data are the following:

Actual time of the sampling period in ms TTTTT (5 car.) Instantaneous hourly flow rate FFFFFF (6 car.) Belt speed in cm/min SSSSSS (6 car.) Number of encoder counted pulses PPPPPPPP (8 car.) Detected weight WWWWWWW (7 car.) Manual / automatic operation selectio M (1 car.) Analogue output value in percentage RRR (3 car.) Alarm code A (1 car.)

When each sampling period elapses one data record is sent in the following format (CSV compatible).

In the technical menu it is possible to activate the Data Logger function to transmit the data record in data stream on COM2 (with USB, RS232 or R485 interface). These data are available for a PC application that stores it in a file for a future analysis, displays it on a monitor screen or shows it in graphic format to highlight the trend over time.

If a the USB Host option is available the data records can be directly saved in a CSV file that is automatically named logxxxx.csv, where instead of x you will find a progressive number. At the file start and end the system adds a line with current date and time. In this case the USB pen drive shall be inserted during the data logging operation.

If you selected the data logger operation on USB file, it is automatically disabled after 3600 records, to avoid having files with a great amount of data in case the function is forgotten active.

6.2 - SAVE AND LOAD SET-UP

With the set-up files saving and loading operations (available in the set-up menu) all parameters that can be set can be transferred from the instrument memory to a PC or a USB memory support and vice versa.

This function can be used to save a copy of the parameters, to store the set-up of one system instrument, to duplicate the same set-up on more instruments, to receive the set-up files of a remote system through the web for technical reasons.

The data transfer occurs on the COM2 communication port (RS485, RS232 or USB device). In case the USB Host option is available and set, the file transfer occurs directly on the USB (pen drive) memory support.

The transferred data are those indicated in the parameters table and identified with the univocal address. The file format is CSV, made up of one table with one parameter per line and 2 columns indicating the

parameter address and value.

In case of transfer on COM2 the load function waits to receive one file whereas the saving function sends data directly to the communication port without waiting handshake operations: the receiving unit must be able to receive data when the control is activated.

In case of transfer on USB pen drive, the memory support shall be entered before the activation of the saving and loading controls. The transferred file has a fixed name: set-up.csv.

The data loading could also be partial, i.e. the table can contain only some parameters (or even just one) and they must not be compulsorily ordered as in the table created by the instrument with the saving operation.

This offers an alternative system for setting up the parameters.

6.2 - FILE LOADING

The file loading operation (available in the set-up menu) allows to set the instrument so as to customise some functions. The display shows a control menu and each control corresponds to one file to be loaded in the instrument.

There are 10 contextual Help text files available that can be transferred from the instrument memory to the PC or a USB memory support and vice versa.

H01.TXT Help text waiting for controls of the main window H02.TXT Help text in numeric data set-up H03.TXT Help text in selectable data set-up H04.TXT Help text for warning or confirmation windows H05.TXT Help text in the total section H06.TXT Help text in the setpoint section H07.TXT Help text in the hourly flow rate section H08.TXT Help text in confirmation of the calculated K correction factor H09.TXT Help text in the default zero weight calibration function H10.TXT Help text in the default 2mV/V weight calibration function SPLASH.BMP Image displayed upon instrument switching-on SETPOINT.TXT Names associated with the setpoints

INEXT.TXT Descriptions associated to logic inputs of external modules

The files loading occurs on the COM2 communication port (RS485, RS232 or USB device). In case the USB Host option is available and set, the file loading occurs directly on the USB (pen drive) memory support.

The Help texts are ascii files with max. length of 300 characters. The splash.bmp file shall necessary be a black and white bitmap file (1 bit of colour depth), with fixed

dimensions 120 x 40. The setpoint.txt file is a text constituted by 1 to 15 text lines corresponding to setpoints from 1 to 15.

Each setpoint name can feature maximum 10 characters. File inext.txt is a text file composed of 1 to 8 text lines, corresponding to descriptions assigned to inputs

from 1 to 8 (4 + 4) on the two external I/O modules. Each description can be composed by up to 16 characters (we recommend to check the visualization on the display, which may vary according to the used characters).

In case of loading from COM2 the loading function waits to receive one file. In case of loading from USB pen drive, the memory support shall be inserted before the activation of

the loading controls.

6.4 - ANALOGUE MODULE

( OPTIONAL)

MC 353 instrument can handle up to 3 external analogue modules. Transmittable data may be density, speed and weigh (or weigh per meter)

Full scale reference can be set through page “SYSTEM SETUP” (parameters “FS Speed”, “FS Weigh”, “FS Density”.

For further details see the specific manual.

6.5 - RELAY MODULE

Relay module MOD-RELE’, connected through COM2 (RS485) to the MC 353 instruments, can handle an additional 8 outputs and 4 inputs.

Each MC 353 instrument can be connected to a total of 2 relay modules at the same time, handling this way up to 16 outputs and 8 inputs.

INPUTS: Relay module, through serial port, transmits status of inputs to MC 353 instrument. The input status is converted to specific registry status of inputs on the ModBus/Profibus registry.

It is possible to program the instrument so the status of a certain input on the relay module may generate a general alarm on MC 353 instrument.

ON status of inputs does not involves other operating procedures on the instrument. OUTPUT: status of module’s output is determined by the ModBus/Profibus registry, transmitted to the

PC/PLC by MC 353 instrument.

For further details see the specific manual.

ERROR MANAGEMENT (Ref. Par. OPERATING ALARMS) [Err. PROFIBUS] Communication failure error between Modbus and S125 module : after 5 consecutive communication time-outs. A communication reset is automatically executed, but if

it fails the error is displayed and you can manually reset the error by pressing the RESET push-button. [NoCom. PROFIBUS] Off-Line PROFIBUS network error: for example in case of failed connection of S125

module with the Profibus network. This error is automatically muted upon standard connection reset. [CRC PROFIBUS] CRC error in Modbus communication.

The timeout on module answer is fixed at 100mS.

RESET PROCEDURE FOR EXTERNAL MODULE (S125) As no hardware reset line is available, module shall be switched off and on after the following operations:

- module first connection to the instrument;

- following changes of PROFIBUS address. When the module is internal, such procedure is automatically handled by the software.

INPUT and OUTPUT AREA MANAGEMENT: module’s default setting is a fixed configuration of input and output areas. Programmable parameters are identified and listed on a list included in module’s manual. Eventually, through a specific application (PWIN 75) is possible to configure I/O areas of PROFIBUS DP and PROFINET IO field buses, in order to obtain an ordered list of parameters to meet application specifications. The GSD, GSDML files and PWIN 75 application are available in our web site under the ‘download’ area.

PROFIBUS / PROFINET CONNECTION TEST PROCEDURE

Profibus Master (E.g. PLC) may verify connection of the instrument to Profibus network by the following procedure:

1. Master writes a value (e.g. counter) on Test Register Out (bytes 6-7 of Output Area);

2. Instrument copies that value to Test Register In of Input Area; Master verifies that the value read from input Area is the same value written at position 1

CUSTOM MAPING OF INPUT AND OUTPUT AREAS It is possible to configure the PROFIBUS DP and PROFINET IO field buses I/O areas, to obtain an

ordered list of parameters according to the specific needs of the system.

This configuration is done using a specific utility (PCWIN 75) connected to the RS232/USB port COM2 of the instrument (communication parameters selectable).

The configurator PCWIN75 presents a user-friendly graphical environment through which compose the areas of I / O: at each register can be associated with one parameter selected from a down list menu.

It is possible to customize up to 2 pages of INPUT and 1 page of OUTPUT. The application can be downloaded in ns. website.

PROGRAMMING AREAS I / O (PC -> Touchscreen)

Through LOAD PROFI IO function, accessible from the setup menu when turned on, the touch screen is enabled to receive the configuration.

Proceed with the submission of data by pressing the SEND button in the dialog of the configurator.

READING AREAS I / O (PC <- Touchscreen)

Set your PC to receive data by pressing the GET in the mask in the Configurator. Using the SAVE PROFI IO function, accessible from the Setup Menu when turned on, the touch screen

will proceed with sending the configuration currently in memory.

RESTORE THE AREAS OF I / O TO DEFAULT

By entering the password in 1012 function (FACTORY SETUP) accessible from Setup Menu when turned on, you can restore the areas of INPUT to the default values or those in the following pages. This operation will also lead to the cancellation of the customized OUTPUT .

COMPATIBILITY WITH PREVIOUS SW VERSIONS

Full compatibility with older software is ensured.

• Area of INPUT: thanks to the function that forces the configuration to default values

• Area OUTPUT: compatibility is guaranteed, because the meaning of the area registers always depends

on the value of the command register.

DETAILS MAPPING

• Area of INPUT: The first register of the Input always identifies the page number, the next 63 registers

are customizable. And it is possible but not mandatory to define up to two customized virtual pages.

• Area OUTPUT: The first register of the Output is always the Command Register.

Is maintained the logic according to which the value of the Command Register identifies the meaning of the subsequent 63 registers available. A new command “activation area custom Output” (7FFFh) is set: until the Command Register contains this command, the 63 following registers are directly accessible and match the custom parameters defined by the user. You can define only one single page of customized output.

It is possible to connect a repetitor (RIPH20, RIPH60, RIPH100, RIPH160) in parallel with the slaves to display the transmitted value.

7.4 - SUPERVISION FUNCTIONS

The supervision functions by one PC/PLC are carried out through the COM1 communication port (RS422 / RS485 or optional Ethernet ).

The communication protocol used is MODBUS RTU, with records that can be set whose addresses are listed in the parameters table and they shall be added the value 40000.

Following are the ModBus supported functions:

- READ HOLDING ADJ

- PRESET SINGLE ADJ

- PRESET MULTIPLE ADJ

Address Parameter 0151 Max Flow Rate (HIGH WORD) 0152 Max Flow Rate (LOW WORD) 0153 Load Cells Flow Rate (HIGH WORD) 0154 Load Cells Flow Rate.

At the end of the parameter set-up it is necessary to send the ‘3’ control to the command register (address 5001) to save in the permanent memory the applied changes before switching off the instrument.

Some parameters feature 32 bits and thus they are made up of one couple of 2 records with consecutive address. Near is the concerned parameters list. All other parameters feature 16 bits (1 modbus record).

7.5 - MASTER / SLAVE COMMUNICATION PROTOCOL

The instrument can be configured to operate as master of other instruments or as slave. In the first case the detected hourly flow rate percentage with respect to the scale end is transmitted continuously to the slaves which adjust the flow rate setpoint according to the received percentage.

This function can be implemented with RS485 serial connection on COM2 by suitably setting the 0104 parameter.

The communication string is sent to the frequency of 10 Hz, by using the communication parameters set for the COM2 port that shall be the same on all instruments.

It is possible to connect a repetitor to the instrument (RIPH20, RIPH60, RIPH100, RIPH160) to display the transmitted value.7.6 - REPETITOR TRANSMISSION PROTOCOL

SCHEDULE

Using the MODBUS-RTU and ASCII in which the instrument acts as a SLAVE, consider that:

- MASTER timeout for each transmitted query must be submitted for at least 25 ms; at this time, add also the transmission time of the query and the time of receipt of the response, which depends on the baud rate.

- The MASTER must be able to resume operation after a communication error (string not recognized or framing error).

8.1 - TROUBLESHOOTING

Hereinafter is a list of the most frequent questions and answers relating to problems which may arise upon MC 353 electronics installation and operation.

Anyway, should you have further doubts or problems, contact the technical service.

Question Possible cause Possible solution

Belt turns but instrument

does not display any ow rate

value

- Instrument does not receive the run input

- Load cell does not issue a correct signal to instrument

- Encoder does not send pulses to instrument

1- Press COST 3 times, and check that in the input line

the rst digit is at 1). In case of

negative output, check wiring harness and operating logic

2- Check the signal coming from the load cell (displayed on weight box); it shall be positive and, when exerting a pressure on the weighing bridge, it has to increase. Using a tester, measure the value in millivolts between S+ and S-: it shall be between 0 and 10mV. If necessary, check cell wiring harness, its correct installation, and also check that the weighing system has been mechanically released.

3- Check correct coupling between belt drum and encoder shaft. Check also that shaft is turning.

The instrument displays ALL-ADJUSTMENT

- Adjustment impossible (instrument cannot reach the set SET-POINT)

4- Check that the material on the weighing system is suitable to the selected SETPOINT. Should this not be the case, change the height of the extraction gate, if any. Check that motor speed range allows achieving the

required ow rate.

The instrument displays ALL-ENCODER

The instrument displays ALL-MIN.WEIGHT

The instrument displays ALL-LOAD CELL

The instrument receives the run input, but belt does not turn

- Encoder does not send pulses to instrument

- No material

- Zero setting error

- Locked load cells

- Problems due to load cells

- A value too low has been set in the WEIGHT TIMEOUT parameter

- Instrument analogue output (if set as an adjuster) does not correctly transmits the signal to drive or inverter

- Wrong work data set on the instrument

- Mechanical problems

- Electrical problems

3- Check correct coupling between belt drum and encoder shaft. Check also that shaft is turning.

5- Check for the presence of material on the weighing system

6- Execute or repeat the ZERO setting

7- Operate on the block positioned under load cells so as to leave a gap of a few millimetres for the cell to bend and thus give a correct weight

See points 2 and 7

8- Check and increase the time set in WEIGHT TIMEOUT parameter

9- Check that the analogue output adopted by the instrument corresponds to the one pre-set in the driver. Check wiring harness.

10- Check that (in case instrument is in MANUAL mode) the percentage set on the instrument does not correspond to the M00% value. If working in AUTOMATIC

mode, make sure that a ow

rate value has been entered in the selected SET POINT

11- Check that drive roller adheres to belt, thus transferring the motion.

12- Check for motor correct operation, and check that it turns in the correct direction
