INSTALLATION
To obtain the best results it is recommended to install the indicator and the platform (or transducer) in a place with the following conditions: - a flat, level surface on which to rest; - stable and vibration free; - no dust or strong vapours; - no draughts; - make sure the platform is level or that the loading cells are resting evenly; - moderate temperature and humidity (15-30°C and 40-70%); - do not install anywhere where there is the risk of explosion; - all the indicator connections have to be made respecting the rules applicable in the zone and in the installing environment. Respect the recommended electrical precautionary measures described in section 1.1; - make sure that the grounding is made correctly, see section 1.2; - everything not expressly described in this manual has to be considered as improper use of the equipment; - avoid welding with load cells installed; - use waterproof sheaths and couplings in order to protect the load cell cables; - use a waterproof junction box to connect the cells.
1.1
Electrical precautionary measures
Please follow the listed precautions: - mains power supply is restricted to within ± 10% of the rated voltage; - electric protections (fuses etc.) are provided by the technician installing the instrument; - respect the recommended minimal distances that are mentioned for the various cable categories; - the extension leads of the load cells or signal amplifiers, used for the connection of the serial ports and analogue output must be within the allowed maximum lengths, see section 1.2; - the extension leads of the load cells or signal amplifiers must be screened. In addition they must be laid on their own in a raceway or metal pipe as far away as possible from the power supply cables; - install “RC” filters on the contactor coils, on the solenoid valves and on all devices producing electric disturbances; - if it is possible that condensation could form inside the weight transmitter it is advisable to leave the instrument powered at all times;

1.2
every shielded cable or not (for instance PC cable, cell cable, power supply cable) connected to the indicator should be as shorter as possible, then you have to come out of the shield the minimum length of cable, then connect to the terminal box; if the indicator is situated inside an electric panel, the power supply cable should be a shielded cable as shorter as possible, distant from every coil supply cable, inverter, electromotive force, etc. and in addition dedicate an uncoupler transformer in order to feed the indicator only.
Earthing system
For the right earthing and the optimal functioning of the system, it is necessary to connect the indicator, the load cells, the possible junction box and the weighing structure to the earth. All earthing cables must have the shortest possible length in order to minimize their resistance. 1.2.1 Indicator Connect the external earthing of the indicator to the earth through copper cables having at least a 16 mm2 cross-section. 1.2.2 Load cells and junction box The earthing must be done by connecting the earthing cables to a ground bar with cables having a cross-section of at least 16 mm2 and by connecting the ground bar to a ground pole with a cable having a cross-section of at least 50 mm2. - In the case the load cells are connected to the indicator through a junction box, it is necessary to connect the sheathing both of cells cables and of indicator cable to the earthing of the junction box (refer to the junction box manual) and connect this to the earth through copper cables having at least a 16 mm2 cross-section. - If the load cells are connected directly to the indicator (without the use of the junction box), one should connect the shielding of the load cell cables to the grounding point (or earthing bar) inside the container. - If the weighing system concerns large and/or outdoor structures, like weighbridges, and the junction box is connected to the indicator in a distance that is greater than 10 m, or in the presence of noise, the cable shield must be earthed both in the junction box and in the indicator, and the two ground leads must be connected with an earth cable having a crosssection of at least 16 mm2 . 1.2.3 Weighing structure Connect the weighing structure and the possible connected structures (for example silos that release material on the weighing structure) to the earth through copper cables having at least a 16 mm2 cross-section. Furthermore it is necessary that for each cell, one connects the upper part with the lower part of the load cell through a copper braid section not less than 16 mm2; the upper part must be shortcircuited with the surface of the weighing structure and the lower part must be grounded through a copper braid section not less than 16 mm2.

INSTALLATION
1.2.4 General Notes All the grounding cables must have an adequate length, in order to obtain an overall resistance of grounding system less than 1Ω. In the case the weighing system regards great and/or outdoor structures, like weighbridges: the grounding connection is to be made by connecting the grounding cables to a grounding bar and the grounding bar to the grounding pole with a cable section not less than 50 mm2; the cable cross-section must be greater (for example 50 mm2 instead of 16 mm2 and 100 mm2 instead of 50 mm2), because the voltage into play is greater (for example thunderbolts); the ground pole must be positioned at a distance of at least 10 meters from the weighbridge structure; one needs to open the SENSE inside the indicator in order to offset the drifts due to the increase in temperature. One should check and remove, if necessary, the connection between the earth and the neutral wire of the electrical installation.
1.3
Connection to the load receiver
1.3.1 Analog load cells After having followed the instructions regarding the platform or the load receiver, the screened cable leading from the load cell(s) must be connected to the instrument through the CELL1 terminal board and the CELL1, CELL2, CELL3, CELL4 connectors; see section 0. The CELL1 terminal board of the indicator may be connected to the 6-wire load receiver (with use of SENSE), or simply 4-wire; for this, through 2 jumpers it is possible to choose whether to shortcircuit the SENSE with the POWER SUPPLY (jumpers closed) or not (jumpers open). The sense allows compensating for any drops in voltage in the part of the cable that connects the instrument to the transducer. It is useful when the distance between the indicator and the transducer is greater than 10 m. The 4-pin connectors instead allow just the 4-wire connection. To make the connection qualified personnel must open the instrument (see terminal board connections in the section 0). TAKE NOTE: if there is just one LOAD RECEIVER, it is possible to make a 6-wire connection (use of sense) directly with the terminal board, removing 2 jumpers for the sense. If there are two or more LOAD RECEIVERS, one should close the 2 jumpers (sense and power supply are short-circuited) and make the 4-wire connection. Normally the indicator comes already connected to the platform and is ready to use. If this is a LEGAL FOR TRADE instrument, access to the connection will be subject to a legal SEAL. Follow the instructions for preparing the platform for use. 15

Serial line connection
The connection of the serial ports must be made by technical personnel who knows the procedures on the basis of the user’s needs. The data transmission cable must be kept away from the AC power supply lines.
!! REMOVE VOLTAGE BEFORE OPENING THE INSTRUMENT !! 1.4.1 RS485 connection Below is the RS485 connection of the indicator in the 485 port: TERMINAL DFWL COM1-485 A(+) B(-)
DFW DF485 BOARD A(+) B(-) -
SIGNAL TX+/RX+ TX-/RXShield
Line 485 + Line 485 Earth
See terminal board connections in the section 0. On the same RS485 line it’s possible to connect up to 32 devices, among indicators, digital load cells, DGX conversion cards or 485/232 signal converter. 17
INSTALLATION

Use a STP (Shielded Twisted Pair) cable in order to make the connection (twisted and shielded pair/s with single shielding for each pair through aluminium band and total shielding through external sheathing). The maximum reachable length from the line with the use of the appropriate cable for RS 485 connections, the twisted 2x24 AWG duplex cable, shielded with external sheathing + aluminium band, is of about 1200 meters. With very long cables, the cable capacity (normally near 50pF/m) starts being a dominant factor in the power consumption and increases with the increase of speed. This implies that the maximum distance cannot be covered with the maximum possible speed. For an approximate value, one can consult the following table: Baud rate

Verify that the grounding satisfies the requirements of section 1.2. Especially, all the digital masses, as well as the analogue masses, and the power circuits, must be connected to the grounding bar and this last one must be connected to the grounding pole. The shielding can be connected into a single point of the entire network (as shown in Figure 1) or both its ends, however it’s important that all the masses have the same potential, in order to avoid the forming of current rings.
INSTALLATION

On the RS485 network normally one connects 2 termination resistances equal to the characteristic impedance of the cable (typically 120 Ω, see Figure 3), ONLY on the 2 devices which are at the 2 ends of the ring connection (for example indicator and last device). The terminal resistance is not supplied with the ports of the indicator. The difference of potential between the A(+) and B(-) terminals in rest conditions (for example with instrument in set-up phase), must be of at least 0,2 V. To create a resistive divider which maintains this difference of potential also when all the transmitters are disabled, insert in the RS485 port of the indicator where there are the termination resistances, the polarisation or fail-safe resistances (RFS in Figure 3). The value of these resistances is between 390 Ω and 2,2 kΩ. NOTE: in particular, the value of each of these resistances must be greater than the value calculable through the formula: Req Vdc RFS 1 2 0,2 in which: Vdc is the power supply voltage of the line Req is the overall resistance to the A(+) a B(-) heads, supplied by the parallel of the 2 termination resistances and all the input resistances of the devices connected to the bus.
-
FOR EXAMPLE: Presuming that a connection has 120 Ω as termination resistance and 32 connected devices, each having an input impedance of 12 kΩ. The Vdc power supply is 5 V. One calculates Req , equal to about 52 Ω, and RFS which must be at least equal to 624 Ω. In case of connection with non Dini Argeo devices, there may be different ways of line marking: generally one presumes that the A/B indication corresponds to the +/- and HI/LO markings, but this is not always true. Therefore, if the device does not function, one should try inverting the connections even if everything seems to be correct.

Repe.dc - Protocol rEPE_dC The “RepeaterDC Protocol” is a communication protocol designed to control one or more remote weigh repeater(s) connected via a serial line possibly shared with digital cells, in order to make the best use of a single connection. Packets are sent by the weigher instrument to the repeater(s) at the end of a digital-cells enquire loop, one ID for each loop, when at least 100ms are elapsed from the last packet transmission. This means that a minimum interval of 100ms between repeaterDC packets is guaranteed. If no digital-cell is connected, RepeaterDC packets are sent with a fixed 100ms interval. No acknowledge message from receiver is expected. In the weighers you can select the number of scales. After that, when you set the “repeDC” protocol it’s requested, for each scale present and for the sum of all, if you want to see these always or never or (only if the scale or the sum is selected). In the repeater, after you have select the protocol, is necessary going to “Add.En” step and select the number of the scale then you will see, or the following number of the last scale for view the sum. You can use this protocol with 232 (analog cells) or with 485 (analog/digital cells). w.repe - Protocol W_rEPE It repeats the weight of the remote scale connected. The parameters to set in the repeater are described above (see section 4.2 Com.PC) and they are variable depending on the connected scale.

Transmission & temporary saving of the label programmed in the labeller. By pressing the ENTER key the instrument will temporarily saves the label in the labeller memory; by turning the printer off the label will be cancelled. Carefully read the section “SAVING THE LABEL IN THE LABELLER’S PERMANENT MEMORY”. Saving the label in the labeller’s permanent memory Once the programming of the label has been made, one should: 1. Download the label created in the labeller press ENTER when the display shows the "downld" step. 2. Press the C key; the display shows the message "l.save?": press the ENTER key to save the label created in the labeller’s permanent memory. When saving the data on the labeller, the led blinks; while this happens do not do anything with the indicator or the labeller. The saving of the label ends when this led does not blink any more. The labeller has the label saved and is ready to print it; turning off the labeller does not cause the loss of the saved data. REPEAT THESE SAVING OPERATIONS EACH TIME THAT ONE MODIFIES THE LABEL OR THE DATA IN IT OR IF IT IS NECESSARY TO CHANGE THE FUNCTIONING MODE AFTER HAVING PROGRAMMED THE LABEL.
110
TECHNICAL SETUP
Saving the label in the labeller’s permanent memory in master/slave systems To save the label for the sum of the weights programmed in the MASTER, one should follow the procedure described in the paragraph “SAVING THE LABEL IN THE LABELLER’S PERMANENT MEMORY”. To save the label programmed in one or more SLAVES one should: 1. On each SLAVE, exchange the selected PC serial port ( >> >> step) with the other available port, to allow the transmission of the label format to the MASTER. 2. On the MASTER, enter in the >> step and press ENTER (the display shows “ ”), then press again ENTER (the display shows “ ”): the MASTER can send to the PRN serial port the data received on the PC serial port. 3. For each SLAVE, follow the procedure described in the paragraph “SAVING THE LABEL IN THE LABELLER’S PERMANENT MEMORY” and then set the step at the original value.

In this configuration the instrument keys take on the following meanings (functions): ZERO It decreases the selected digit (blinking). TARE It increases the selected digit (blinking) MODE It selects the digit (blinking) from left to right. ENTER By pressing once after have a value has been entered, it enables the corresponding output analogue value, (allowing the check) but remains still inside the step in case of a new modification. By pressing a second time (on the same entered value), it confirms and exits the step. C It allows to quickly zero the present value. NUMERIC In the 17-key indicator, these allow to enter values, from right KEYS to left.

Communication modes
Please find below the various selectable serial weight transmission modes of the PC serial port through the corresponding “pCmode” step of the SET-UP environment.
TRANSMISSION REQUESTED FROM AN EXTERNAL DEVICE (
)
In this case the indicator waits for a command before transmitting (see the section “Format of the serial commands”). With Baud rate at 9600, through the READ command, it is possible to make up to 14 requests per second, while with the Baud rate at 115200 through the READ command, it is possible to make up to 24 requests per second. The transmission works with weight <, =, > 0 with approved or unapproved instrument. NOTE: This protocol is active also in the other functioning modes, only on the PC serial output.
126
SERIAL COMMUNICATION
TRANSMISSION IN RS 485 SERIAL MODE (485) The protocol is the same as the transmission upon request (ondE parameter), except that the instrument responds only if its machine code is the one requested (before the request the machine code must be put, I.E. 00READ). If a broadcast address command (99) is received no answer is given. If the command is correct it is executed anyways.
TRANSMISSION IN R.ADC MODE (r.adC) The protocol is used for the communication with the WWSERF platforms.
4 – 6 DIGIT REMOTE DISPLAY TRANSMISSION (repe.4 and repe.6) The weight displaying takes place both in the indicator as well as in a weight repeater of 4 or 6 digits, (normally the capacity will be properly set up for a correct displaying). NOTE: Independently from the set transmission speed it’s possible to obtain up to 6 transmissions per second.
TRANSMISSION WHEN THE PRINT KEY IS PRESSED (prin.st and prin.ex) The instrument communicates the weight data through the serial port when the ENTER/PRINT key is pressed (except for in the TOTALIZER mode in which one should press the MODE key or takes place automatically in case of automatic totalisation). For non approved instruments: - The transmission takes place if the weight is stable and the net weight is > 0, otherwise the display shows the “low” message. - Reenabling the transmission depends on how the “reaCt” step has been set in the SET-UP environment (passing by zero of the NET weight, weight instability or always). For approved instruments: - The transmission takes place if the weight is stable and the net weight is > 20 divisions, otherwise the display shows the “LOW” message. - Reenabling the transmission depends on how the “reaCt” step has been set in the SET-UP environment (passing by zero of the NET weight, weight instability or always). The data is transmitted using the standard string (prin.st) or the extended string (prin.ex); see the section “Transmission protocols” for the description of the two strings. 127
SERIAL COMMUNICATION
Notes: - The transmission is confirmed by the “trasm” message on the display or from the “print” or “tot” messages in the case in which the transmission takes place at the same time of the printing or totalisation. - In any case it’s possible to receive data through the transmission commands upon request. - With an unstable weight the display shows the “unstab” message. - If the transmission has not been reenabled the display shows the “no.0.uns” message. - In any case it’s possible to receive the data through the transmission commands upon request.
CONTINUOUS TRANSMISSION (all.std and all.ext) This mode is used for interfacing to the PC, remote displays and other devices which request a constant updating of the data independently from the weight stability. If one selects this mode for the PC, independently from the set transmission speed one can obtain up to 26 transmissions per second. If one selects this mode for the PRINTER port, the instrument transmits the data in relation to the set transmission speed: - With Baud rate at 9600 one can obtain up to 24 transmissions per second. - With Baud rate at 115200 one can obtain up to 26 transmissions per second. The transmission works with weight <, =, > 0 with approved or unapproved instrument. The data is transmitted using the standard string (all.std) or the extended string (all.ext); see the section “Transmission protocols” for the description of the two strings.
TRANSMISSION UPON STABILITY (all.std and all.ext) Each time a weight on the scale becomes stable, a communication string is transmitted on the PC serial port. For non approved instruments: - The transmission takes place if the weight is stable and the net weight is > 10 divisions. - Reenabling the transmission depends on how the “rEACt” step has been set in the SET-UP environment (passage by zero of the NET weight or instability of the NET weight of 10 divisions; by choosing “always” it works upon instability). For approved instruments: - The transmission takes place if the weight is stable and the net weight is > 20 divisions. - Reenabling the transmission depends on how the “rEACt” step has been set in the SET-UP environment (passage by zero of the NET weight or instability of the NET weight of 20 divisions; by choosing “always” it works upon instability). The data is transmitted using the standard string (stab.st) or the extended string (stab.ex); see the section “Transmission protocols” for the description of the two strings.

Furthermore the printout on the printer port will also include the ALIBI rewriting and weigh number, at the beginning of the printout. The identification of the weigh takes place through the ID code; a code is given to each weigh, allowing to find the weigh in the database. The ID has the following format: < Rewriting number > — < Weigh number > The rewriting number is a number of 5 digits which may go from 0 to 00255; it indicates the number of complete rewritings of the alibi memory. 131
SERIAL COMMUNICATION
The weigh number is a number of 6 digits which may go from 0 to 131071; it indicates the weigh number in the current rewriting of the alibi memory. With each storage the weigh number is increased of 000001; when this reaches the value 131071, it restarts from 000000 and the rewriting number increases of 00001. If the weigh cannot be saved in the alibi, the numeric ID will be substituted with the message "NO".

I/O optional expansion card with 2 inputs and 2 outputs
INPUTS (OPTOISOLATOR PHOTOCOUPLERS) Power supply: 12 Vdc ÷ 24 Vdc (standard configuration: J3 and J4 open); 6Vdc (J3 and J4 close); min 5 mA - max 20 mA. PHOTOMOSFET OUTPUTS Maximum power: 48 Vac or 60 Vdc, 150 mA max., 10 ohm max NOTE: Make sure that J1 is open and J2 is close. It is possible to connect two expansion cards having 2 inputs and 2 outputs each. The first I/O board is connected through a 350 mm cable which connects the BOOT connector (on the indicator board) and the Y1 connector (on the I/O board); the second board instead is connected “in cascade” to the first one with a 350 mm cable (equal to the previous one) which connects the two Y1 and Y2 connectors. With the jumper J5 in two positions (1 and 2) one selects whether the board should manage inputs 1 and 2 and outputs 1 and 2 (J5 in position 1) or whether it should manage inputs 3 and 4 and relays 3 and 4 (J5 in position 2).

Therefore the correct configuration with two cascade boards is: BOARD 1: J5 on 1 (therefore Input 1, Input 2, Output 1, Output 2) BOARD 2: J5 on 2 (therefore Input 3, Input 4, Output 3, Output 4) The inputs will be put outside the instrument with a 12 X 0,5 mm multipolar cable connected in this way: MEANING COLOUR OUT1 WHITE OUT2 GREY OUTCOM (common outputs) BLACK IN1 RED IN2 BLUE INCOM (common input) BROWN + VE (+12 Vdc) WHITE - GREEN - VE (GND) WHITE - BROWN ONLY WITH SECOND CONNECTED I/O CARD: OUT3 PINK OUT4 GREEN IN3 YELLOW IN4 PURPLE The optoisolation of the inputs is not correct anymore if these are activated with a voltage available on the indicator (for example the VE); an external voltage must be used instead. However, for convenience’s sake the VE of the indicator is brought onto the multipolar cable. !!!WARNING!!! Be careful not to short-circuit the wires of the VE (WHITE – BROWN and WHITE – GREEN wires) since this would cause permanent damages to the electronic card. 5.5 Connection of the electronic TILT sensor Indicator Electronic TILT Meaning (SENSOR) Y1 1 1 +5V – Sensor power supply + 2 2 GND - Sensor power supply 3 3 TILT Signal 4 4 t-power - TTL Power must be set ON to enable the 5V power supply on the SENSOR connector.
