Safety Information

VIALE INDUSTRIA - 12051 ALBA (CN) - ITALIA TEL. (0173) 314111 TELEX 212357 BIANCO-I TELEFAX ITALIA (0)173 - 34872 - 297000 - 297022

Pursuant to law decree 626/94 the owner of a company must inform the workers on the risks associated with the use of the machinery and equipment. Moreover, appropriate information and training must be provided to all employees to enable them to protect themselves and others against accidents. A proper and prudent behaviour on the part of all employees is the first defence against accidents: the laws, standards and provisions contained in this document and even technical prevention measures will have little effect without this awareness. To behave in the appropriate manner is a key factor not only for one’s own protection, but also for that of one’s colleagues; similarly, the safety of everyone depends on the behaviour of others: hence, hazardous jokes should be avoided and so should any action that might distract, or harm, one’s fellow workers. Another crucial factor in accident prevention is attentiveness: being able to keep alert and retain control of our actions can ensure our own safety and that of the people around us. Correct behaviour and due diligence may not suffice to protect us against accidents; many hazard conditions, in fact, can be unpredictable and accidents may take place without any warning signs. For these reasons, we should comply with a series of rules and standards developed from the experience and knowledge accumulated by everyone. Users should comply very carefully to the following provisions. 1. Read the user manual before using the machine and follow the instructions imparted by the supervisors. 2. The machine should be used solely by specially trained personnel. 3. The machine and the relative workstation must be placed in a well illuminated area. 4. Do not encumber the working spaces around the machine. 5. The use and adjustment of the machine can be performed only by the operator in charge: access to the machine by unauthorised personnel is strictly prohibited. 6. Do not remove the safety guards without express permission and inform the supervisors of any malfunctioning of the safety and protection mechanisms, as well as any hazard condition you may become aware of. 7. Do not connect the machine electrically or pneumatically by means of flying cables and/or pipes, which might hinder the regular movement of people and things.

8. Check daily the efficiency of the safety devices and controls. It is forbidden to remove, modify or tamper with the control units of the machine and their protections against accidental starting. 9. Keep the working area free from foreign objects: the work station must be clean and orderly. The floor must not be encumbered with materials extraneous to the job in hand or processing scraps. Prevent the accidental spilling of greasy or oily substances: if this were to happen, clean the floor at once. 10. Use personal protection equipment and appropriate work clothes. 11. Entrust maintenance works to specially trained personnel. Tools must be used solely for the purposes they are intended for in the most appropriate manner. 12. It is forbidden to clean, oil or grease any machine part by hand, unless this is required by specific technical needs: in the latter case, use appropriate tools to prevent all conceivable hazards. 13. The drawing-in process must always be performed after deactivating the system by means of the key-operated switch located on the console and after removing the key, so as to prevent the risk of accidental starting. 14. After any maintenance intervention on the machine parts, return them to their original position. 15. If the supply of compressed air is cut off while the machine is running, and unless this is done automatically, close the air cut-off valve or discon 16. Before performing any operation on parts that may start moving abruptly, stop the machine and discharge the residual pressure from the pneumatic system, if this has not been done automatically by the ad hoc valve. 17. The use of compressed air to clean the equipment, parts of the machine, finished products, etc. must be limited to the cases envisaged by the production cycle, making use of the means of protection provided to prevent accidents. It is strictly forbidden to use compressed air to clean people and clothes.

2.2. Weft strainghtener operation The weft straightener automatically eliminates any distortions in the fabric weft as may be caused by the different manufacturing processes after weaving. Then the fabric passes alternatively between curved and diagonal rollers and between the optic reading heads, as described in figure 5. When the mobile frame (3) carrying the rollers (2) begins to oscillate, half the fabric is pulled from the centre towards the corresponding edge; as half the fabric is pulled towards the edge the other half relaxes thereby enabling diagonal distortions to be corrected. The other set of rollers (1) has a curved axis which can be aimed so as to present a more or less marked convexity towards the fabric wound around it and thereby apply to the fabric a force which gradually increases from the edges to the centre. This force enables curved distortions to be corrected. The reading heads (4) (5) detect weft distortions in the fabric leaving the weft straightener and supply a signal to a control unit which interprets the signal, processes it and transforms it into control pulses to the correction roller motors. Curved roller rotation is by means of a variable speed geared motor (8), whose speed is controlled by the dynamo fitted to machine downstream and by the compensation roller (7), so as control fabric feed as a function of the requirements of the machine downstream. Before passing through the correction rollers, the fabric is wound around the spreading roller (11) which spreads it and eliminates any creases that might be present. A similar operation is performed by means of the spreading roller (12) located right before the reading bridge.

5. HANDLING The unit is generally packaged and moved in a crate, without having to take down its constituent parts, other than the brake assembly. SAFETY RECOMMENDATIONS Before proceeding with machine transport, make sure it contains no loose items: any parts which are not firmly fixed must be removed, to prevent their accidental movements from changing the position of the centre of gravity and undermine the stability of the component when it is harnessedand lifted. To unload the unit at the customer’s plant, we recommend lifting and moving the unit by means of a fork lift truck. Make sure that the length of the forks is appropriate to guarantee the stability of the load and that truck capacity is sufficient. The fork lift truck must be driven by a qualified operator and the handling process must be supervised by another person to ensure that transport operations are completed in full safety. If any signs of unbalance are observed as you start lifting the unit, lower it immediately and make sure that the centre of gravity has been identified correctly. Avoid collisions and swinging movements during the handling process. Use low translation speeds. The unit can be moved solely by means of appropriate lifting tools (cranes, bridge cranes, hoists, etc.). When it has been removed from its packaging, hook up the unit with ropes passing through its eyebolts, as shown in figure 3. Check the conditions of the ropes, i.e. make sure there are undamaged and conforming to the standards.

6. INSTALLATION AND START UP Installation operations must be carried out by qualified personnel. The following paragraphs describe the weft straightener and reading bridge installation and start up procedures to be performed at the customer's premises.

6.1 Assembly Preliminary checks Remove all packaging materials and make sure that the mechanical parts are undamaged. Check voltage rating. Check for loose parts (e.g. damage to the tachometric dynamo). Alignment The machine must be placed perfectly level and aligned with the following unit (usually, the tenter frame). This condition is indispensable not to introduce fabric distortions which cannot be controlled. When assembling the reading bridge structure, it is essential to comply with the head-fabric distances specified (head focusing distance). Anchorage The machine must be anchored firmly. The anchoring procedure is described in paragraph 6.2 below. Vibrations Make sure no harmful vibrations are transmitted to the machine as may be produced by fitting devices that are not perfectly balanced or connecting the machine to the adjacent units by means of fastening brackets. Vibration may affect fabric readings and cause electrical system malfunctions. Separate cubicle In some versions (e.g. the reading bridge), the electrical equipment is separate from the machine. Follow with care the wiring instructions, complying with all the cable cross-section and max length provisions given in the wiring diagram.

Accessibility To do their job, maintenance personnel must be able to open fully the access doors to the machine sides and the electrical equipment. The reading head covers must also be accessible. Projector covers must be within easy reah for bulb replacement. Heat sources Do not place the electric cubicle (if separate from the machine) next to direct heat sources or steam nozzles. Do not expose it to direct sunlight through the windows. Optic system cleaning Make sure the optic system is clean. If necessary, clean carefully the reading head and projector lenses. Use a soft cloth, free from grease, and possibly a compressed air jet. Speed line reference dynamo Mod. MDC weft straightener (with pulling system) requires a voltage reference proportional to the line speed. As a rule, a tachometric dynamo is supplied, to be fitted to the first driven roller of the next machine. Make sure that the transmission of motion does not take place from rollers over-powered or under-powered compared to fabric feed speed in the straightener. Dimension the coupling pulleys so that max line speed shall correspond to a speed of rotation of the dynamo of 1000/1500 rpm (corresponding to 60/ 90 volt in dynamos with 0.06 volt/rpm) to take full advantage of the signal supplied and minimise disturbances. Make the coupling with accuracy, so as to prevent irregular movements or jolts from occurring even at low speed. To ensure trouble-free operation, the motion of the dynamo must be steady. Jolting of the dandy roll during machine operation may depend on the regularity of the signal supplied by the dynamo. Electrical connections The electrical connections are on the left side of the machine (in the direction of fabric feed). Power the machine via a three-pole + ground electric cable with crosssection as specified in the wiring diagram. Collect the tachometric dynamo (only for the MDC model) by means of a shielded cable of the required cross-section as specified in the wiring diagram. Refer to the wiring diagram supplied with the machine for details.

Exchange of enable signals and other signals The weft straightener has been designed so that it can be used in a line including other machines and governed by a higher level control unit. To this end, the following contacts are provided for the exchange of enable signals and other signals to external units (see the electrical wiring diagrams): Machine starting is timed and about 10 seconds elapse between the start command and the closing of the ready contact; it is indispensable to set the machine immediately after the weft straightener (generally the tenter) so that it will start upon the actual closing of the contact. Refer to the electrical wiring diagram supplied with the machine.

7.2. Maintenance of the reading system • Clean the reading head lenses every day with a soft cloth. Do not use running water. • At regular intervals, clean the filters in the cubicle ventilation slots and check fan functionality.

8. SAFETY DEVICES AND GUARDS The unit is equipped with the electrical safety devices described in the previous sections and a number of mechanical guards. The presence of the key-operator selector for t unit operating modes means that, once the key has been pulled out and handed in, the machine can be used solely by trained and knowledgeable operators performing deliberate actions. For safety purposes, the operator must never leave his/her work station with the key in the selector during any drawing-in, maintenance or cleaning operations; moreover, the operator must make sure that if any part has been removed, it has been fitted back and fastened firmly in the proper position before starting a new work cycle. In any case, it should be stressed that the unit cannot work independently and therefore is subject to the “STARTING PROHIBITED” provision until it has been incorporated into other machines and cer tified (MANUFACTURER’S DECLARATION). The unit has been designed so that the risks associated with ambient noise are reduced to the minimum, based on technical progress and the availability of appropriate means to attenuate noise, especially at the source, as provided for in decree D.P.R. 459/96 Annex 1, comma 1.5.8. The average value of Weighted Equivalent Noise level (A) with the working parameters of the machine set on optimal values is: L EP,d <70 dB(A). The operator is exposed to no hazard and hence no preventive activity is specified, no indications or reports are required.

The display panel is able to visualise the data in either full screen or reduced to ½ screen mode; the latter mode is used when the Vdtex is connected to 2 or more instruments or machines and is used for the simultaneous presentation of 2 data windows. The list of the machines or instruments connected to the Vdtex is shown by a series of icons aligned in the upper part of the screen. Each icon gives the instrument’s identification number; by typing this number you may recall the visualisation of the instrument concerned. In the ½ screen mode, the instrument recalled is positioned in the bottom part of the screen. You may switch from reduced to full screen visualisation and vice versa by means of the up/down arrow keys. The lower part of the screen displays the main controls and the operating status of instrument or the machine. In the ½ screen mode, you can work the instrument controls visible in the lower part of the screen. To move the visualisation of an instrument to the lower part, press the corresponding identification number.

1.2. List of connected instruments and operating status In the upper part of the screen we find the symbols of the instruments connected to the Vdtex. The number of symbols displayed depends on the installation. In the example given in the figure below, we see the icons representing the weft straightener, the reading bridge and the fabric humidity measuring instrument (Hygrotex).

Each instrument is associated with a progressive identification number. Each symbol can take on 4 colours, whose meaning is: • white: instrument not active (off, defective or not connected) • red: error signal coming from an instrument; to know the details, display the error message page relating to the instrument. when the message has been silenced, the red colouring disappears. • yellow: manual mode operation. • green: automatic control active.

1.12. Autooffset Description Autooffset is a function of the DIGITEX STD1 control system that can be used in systems fitted out with the weft straightener and the reading bridge, or minidigitex, connected to one another by means of a Vdtex computer: it makes it possible to minimise the weft distortion phenomena which may occur in the process after the weft straightener.

This function can only be used in conjunction with a Vdtex computer, and furthermore both the reading bridge and the weft straightener must be of the DIGITEX STD1 type.

Operating principle The reading bridge measures the average distortion of the fabric on the output side and adjusts the offset of the weft straightener located on the input, so as to compensate for the distortion introduced during the process with a distortion of the opposite sign. Applicability The autooffset function can be used only on sufficiently long pieces of homogeneous fabric, since the distance between the weft straightener and the reading bridge necessarily involves a certain delay between the control action can be started; furthermore the evaluation of the average distortion at the output always requires a certain time period. The autooffset makes it possible to remedy the distortion phenomena that come into being after the weft straightener, and it cannot be used to try to improve the action of the weft straightener itself. In actual fact, it will only work effectively if the behaviour of the weft straightener is optimal. Configuration The autooffset must be configured on the basis of system characteristics by means of the KM parameters dedicated to this function (See the section entitled: “Service adjustments: KM parameters”). The configuration must be performed on the basis of the KM parameters of the Digitex STD1control action concerning the reading bridge. When the autooffset has been configured, the bridge data display panel shows a symbol indicating the operating status:

When the autooffset function is off it proves impossible to modify the weft straightener offset manually; this condition is highlighted on the Vdtex computer by the light colouring of the offset setting symbols (the numbers inside the symbols show the offset value set automatically by the reading bridge):

whilst on the OP16 terminal the indication of the offset is preceded by symbol A (autooffset) in lieu of an O (offset).

Operating status The operating status is indicated by the acronym depicted inside the autooffset symbol of the Vdtex or the OP16.

To quit one level and return to the earlier one, it is necessary to display the EXIT command which is always included in the list of commands and press P, or just wait for 30 seconds. A detailed list of the commands is given in the following paragraphs. The following figure illustrates the arrangement of the commands.

2.5. Access codes to the secondary commands (protection keys) Some of the secondary commands are protected by an access key. The OP16 terminal permits 3 machine utilisation levels: levels 1 and 2 call for the introduction of a specific access key; at each level it is possible to perform a certain range of operations in addition to the ones permitted at the lower levels.

3. PARAMETER DESCRIPTION

3.1 KM parameters Space delay before reg. Time delay before reg. These parameters define the delay (in terms of space and/or time) to elapse between line start-up and the activation of automatic adjustment. The equipment waits for the required time interval to elapse and then for the set number of meters to pass before enabling automatic control. It is also possible to use only one of these two parameters, just set on zero the one you do no with to use. Min. stopping time This parameter lets you define the minimum line stopping time after which you wish the “delay before adjustment” to step in. In this manner, a brief line stop will not activate the “delay before adjustment” process (see paragraph “Space/time delay before adjustment” parameters). Min. working speed This represents the minimum speed threshold below which automatic control will not longer work. It is advisable to set values other than 0 to prevent automatic control from working when the line is stationary (see paragraph “Space/time delay before adjustment” parameters). Speed sensor calibration This is used to calibrate the speed measuring system and the meters of fabric processed counter. Speed is measured by means of a static sensor which is excited by the projections of a disk force fitted onto one of the machine cylinders. The set value represents the distance covered by the material between two successive pulses generated by the sensor. Example: disk-sensor assembly with 8 pulses/rev fitted to the axle of a cylinder in contact with the material, with 380 mm circumference: Cyl. circumference 380 mm Pulse spacing = —————————————— = —————— = 47,5 mm No. of pulses 8

To set this value, see the machine start-up procedure too.

Speed sensor average num. This is used to set the number of successive measurements to be performed by the speed sensor in order to obtain an average value. It is useful to filter the speed measurement and improve the stability of the reading. Set n.=1 to have a direct, non-averaged reading. Note: set this number to be the same as the number of pulses / disk revolution to neutralise the oscillations in speed indications due to the error associated with the subdivision of the notches over a revolution. Simulated speed (0=off) This service parameter makes it possible to simulate the measurement of the desired line speed even with the machine stationary or with no speed sensor fitted. It must be set on 0 during regular work. Set a simulated speed higher than the minimum working speed and switch the machine to automatic mode to activate the control system. Machine status This defines the operating conditions of the equipment, according to the following code: 0 = running-in of mechanical parts (forward/return movement of the skew and bow adjustment actuators by means of the limit switches) 1 = stop Weft reading off 2 = Manual mode Weft reading only 3 = Automatic mode Weft reading and control system on This parameter is updated automatically by means of the direct STOP/MAN/ AUTO commands. It is always possible to modify the machine status by working directly on this parameter. Program in use This is used to memorise the number of the selected program. This parameter is updated automatically by means of the program selection control:

The active program can also be changed by working directly on this parameter. Installed heads This is used to set the number of heads installed and connected to the control panel. Furthermore, this parameter established the max. number of heads selectable.

Heads in use Sets the number of heads in use. Its value must be comprised between 2 and the number of heads installed. When the number of heads in use is lower than the number of heads installed, the system progressively cuts out the outermost heads, so as to be able to adjust the number of heads in use to actual fabric height. Set the highest possible value compatible with fabric size. This parameter is updated automatically by means of the following control.

Width % covered by heads Expresses the percentage width of the nominal table of the machine to which the reading heads are applied. Example: in a machine with nominal effective table of 3000 mm, where the distance between external heads turns out to be 2000 mm, the % width covered is given by: (2000/3000)*100 = 66%. This parameter is used only to determine the bow offset. Graphics configuration This parameter defines the direction of the motion of the cylinders after a reset command, the polarity of the graphic and numerical indications of the skew and bow error in relation to the assembly positions of the reading bridge, the Vdtex computer and the skew and bow manual control button strip. Depending on the chosen configuration, the system automatically adapts the polarity of the distortion adjustment outputs. (It is always possible to change the polarity of the adjustment by means of the KM parameters “skew control” and “bow control”). This parameter consists of a numerical code consisting of 5 digits, each of which can take on only the values of 0 and 1, so as to give 32 possible combinations, from code 00000 to code 11111. Each digit identifies the assembly position of a component according to the table given below. In order to establish the assembly position of the reading bridge, the Vdtex computer and the manual skew and bow control button strip, refer to the following sign convention. Sign convention for skew and bow errors: stand ideally along the processing line with your shoulders turned to the fabric input side and facing the output side (as if it were river): in these conditions, the polarity of the indications must be as follows: Direction of movement of the fabric Skew polarity Bow polarity

12 Codes for the assembly position of the reading heads, Vdtex, manual controls: Position yourself ideally on the processing line by turning your back to the fabric input side and facing the output end (as if it were a river flowing): in these conditions, determine the codes according to the following rules:

The codes given above also apply to the manual skew and bow control of the OP16 terminal.

Skew cont. (0=0ff 1/-1=on) Bow cont. (0=0ff 1/-1=on) These parameters are used to activate the skew and bow automatic control, respectively. [ 0] Automatic adjustment is disabled. This setting can be used whenever you wish to use the equipment solely for skew and bow control.

Threshold for prop.regol. This parameter only affects the proportional analog skew and bow control. If the weft distortion is minimal and working speed is low, the system may require a displacement speed lower than the minimum acceptable limit for the actuator employed. This problem is specially important when using actuators with no speed feed-back (e.g. inverter for three-phase motors). The value set by means of this parameter establishes the minimum reference threshold below which the control action takes place by pulses, since it is not possible to obtain a correct management of the motors. Min. impulse for prop.reg. This parameter only affects skew and bow proportional analog control, and has no effects on pulse control. It sets the minimum time duration of a pulse when the proportional reference is below the “Proportional control threshold” (see previous parameter). The value set must ensure the smallest possible displacement of the skew or bow adjustment actuator in the presence of the minimum error (0.1% error and min. working speed). Indicator light mode This is used to define the operating mode of the indicator lights of skew and bow control (see the electrical wiring diagrams for the connections).

Autooffset eval.time This parameter can be used only when a weft-straightener is combined with a reading bridge placed on the output end of the system, and it makes it possible to manage the automatic adjustment of the offset (or “auto-offset”) of the weft-straightener through the evaluation of the average distortion measured at the output by the reading bridge.

Autooffset Bow coeff These parameters can be used only when a weft-straightener is combined with a reading bridge placed on the output end of the system, and make it possible to manage the automatic adjustment of the offset (or “auto-offset”) of the weft-straightener through the evaluation of the average distortion measured at the output by the reading bridge. They must be set on the KM table of the reading bridge. The coefficient determines the variation to be made to the skew or bow offset of the weftstraightener on the input in relation to the average evaluation of distortion. The following formula is applied: offset increment = auto-offset coeff. x average error measured

It is possible to set either positive or negative values to adapt to all installation conditions. If the sign is wrong, the weft will be distorted to an even greater extent.

Exceedingly high values will result in oscillations in control action.

This parameter must be set on the KM table of the reading bridge. The value entered determines the delay between the offset adjustment interventions (the greater is the distance, the greater must be the delay time, line speed being the same).

3.2 KT parameters Skew regulation gain Bow regulation gain The control of the global speed of reaction of the machine is determined by the settings of the KR control parameters. The skew and bow control coefficients (which can be set program by program) permit a further adaptation of the speed of reaction of the machine to meet special needs. By setting a value of 0, the control action is disabled and we can have a working program with only the skew or the bow control action active. For a correct adjustment of the speed of reaction of the machine, set these parameters on 100% (basic setting) and work on the KR parameters (proportional, integrative, derivative gain); then, only if it is really indispensable, use these control coefficients to increase/reduce the speed of reaction of the machine in specific programs. Skew offset Bow offset Setting the skew and bow offsets. These parameters are updated automatically by the commands:

it still proves possible to change the skew or curve offset by working directly on the parameters.

When offset control by means of an external reference signal is selected (see External Offsets parameter KM...) the value set with these parameters is ignored by the control unit.

Skew dead band regulation Bow dead band regulation Expresses the skew or bow error threshold to be passed before the automatic control action steps in. This parameter determines the “blind band” in which the automatic controller does not intervene and it is necessary to avoid unnecessary stresses on the actuator around the work point. By setting this parameter on 0, the control action steps in as soon as the error is other than 0. Sampling position Indication (in degrees) of the displacement (relative to the horizontal axis) of the weft reading zone. For normal weft structures, the reading position is 0 degrees, but some weft structures may require different angles (See figure).

Sampling Window Indication (in degrees) of the width of the weft reading zone. The value is understood as the sum of total width: for instance, by setting 15° we get a reading of between - 15 and + 15 degrees with respect to the reference represented by the reading position. This is illustrated in the following drawing:

Average number Setting the weft signal filtering coefficient: higher values attenuate the variations and improve the stability of the signal.

For problems of compatibility between the Alfa 90 and Alfa 180 reading heads, the “Number of averages for the measurement of distortion” parameter is also used to select the reflex reading mode: all odd settings activate the reflex reading, all even settings activate reading by transparency. Since the machine is equipped with its own control for the activation of the reflex reading system, we recommend using even settings only.

Threshold readability The weft reading system evaluated the readability of the fabric: the score assigned (from 0 &o 100) is shown on the display panel through the following icon.

This parameter defines the minimum readability threshold. When the readability of the fabric drops below the et value, automatic operation is disabled and the skew and bow corrector cylinders move to the neutral position automatically.

3.3 KS parameters Print enable (0=off, 1=on) Enables the transmission of weft distortion data to the print management module: 0=data printing disabled; 1 = enabled. This parameter is updated automatically by the control:

It is still possible to enable the printing of data by working directly on the parameter. For details, see the manual of the printing module. Chart time scale Defines the time scale (x axis) used to plot the evolution of the control error in graphic form. It only affects the charts displayed on screen.

Chart Y scale (skew err.) Chart Y scale (bow err.) Chart Y scale (global err.)

These parameters only affect the charts displayed on screen. 1st skew error threshold 1st bow error threshold 1st glob.error threshold 2st skew error threshold 2st bow error threshold 2st glob.error threshold Setting the alarm thresholds concerning the distortion measured for the skew, bow and global error, respectively. The 1st threshold governs the luminous indications displayed on screen and the alarm outputs (relay contacts), the 2nd threshold is used for the management of print-outs. When the 1st alarm threshold is exceeded, the indications present in the recording instrument light up and the output relay is excited (see list of available connections). The value set with either the 1st or the second threshold are used fro the management of print-outs; see the print module manual.

3.4 KR parameters The KR control parameters are listed in 2 tables: one for skew and one for bow adjustments. In this manner it is possible to diversify and optimise separately the response times of the 2 control actions. Delay compensation The control actuators (e.g., the skew and curved cylinders) are generally situated at a certain distance from the measuring heads. To obtain a prompt reaction of the control system when a change in distortion occurs, it proves necessary to reduce this distance to the minimum. The delay time with which the control action is perceived by the reading heads depends on the speed of the line: increasing speeds make for faster adjustments and vice versa.

Manual control gain Setting the variation ramp of the speed reference of the skew and bow actuators by means of the manual controls. This setting is possible only in the case of analog control and it does not affect contact type ON / OFF control. In actual practice, the manual controls and the analog output form an electronic moto-trimmer in which this parameter established the reference signal variation ramp. The minimum and maximum values reached by the output analog signals, DAC1 and DAC2, can be limited (see the “Minimum/maximum output limitation” parameters). For the standard version of the weft straightener with incremental skew and bow control it is advisable to set 0. Output limit min.value Output limit max.value Setting the variation range admissible in any condition for the analog control outputs contained in board C284 M1-4(DAC1) and M1-9(DAC2). The values must be expressed in volts. Increase 1st ret.impulse In the case of ON/OFF control by means of an electromechanical actuator, mechanical play might be present in the control system drive line and therefore, when the direction of action of the controller is reversed it proves necessary to take up play in the drive line before system adjustment can be obtained again. Thanks to this parameter, if the control direction is reversed, an additional time interval is added to the standard pulse time and is calculated so as to take up play immediately. Minimum impulse This parameter only affects the pulse control outputs (ON/OFF control) and establishes the minimum time duration of the pulse. Control pulses of a shorter time duration and harmonised with the minimum time duration set with this parameter. Exceedingly short pulses cause unnecessary stresses on the equipment and have no useful effects; on the other hand, exceedingly long minimum pulses do not permit a sufficiently fine adjustment. Hence it is important to determine the minimum admissible pulse with care.

Regulation period This established the time interval to elapse between one control pulse and the next. The value to be set depends on the type of actuator available and the rapidity of control that may be obtained: short periods can be used in the case of fast controllers, in which the minimum pulse is also shortlasting. In this connection it should be kept in mind that the “Minimum pulse” and “Regulation period” parameters determine the possible dynamics of the control action, in that the pulse adjustment range varies from 100% (contact permanently closed) to ON/OFF cycles with: minimum time duration of pulse duty-cycle % = ———————————————— x 100 regulation period

2. INSTALLATION

2.1. List of steps to be performed in the installation process The following list describes the sequence of operations necessary to install and configure the print-out management function; the details are given in the following paragraphs. • identify a suitable position where to place the printer. • identify the equipment (Digitex 90, instrumentation) to which you wish to connect the printer. • Position the RS422/RS232 converter in the immediate proximity of the printer. • Extend the connecting cable between the converter and the equipment in which the print-out management module is installed (for the connection, see the wiring diagram). • Configure the Beta90 board (in some instances it might be necessary to replace the software installed or to change the board versions: contact the technical servicing dept.). • Start the Vdtex computer self-configuration procedure so as to enable the computer to recognise the presence of the printer module.

2.2. Positioning the printer and the protocol converter The printer must be placed in a protected position; pay attention to the arrangement of the paper so as to prevent poor alignment or friction from causing paper jams. To set and start the printer, follow the instructions given by the printer manufacturer. The protocol converter must be placed in the proximity of the Beta90 board, so as to minimise the length of the RS232 connecting cable with the printer. Keep in mind that the serial line with protocol RS422 between the converter and the Beta90 board is less vulnerable to noise than the line with protocol RS232. At any rate, make sure the RS422 connecting cable does not run next to power cables or strongly disturbed cables. If any problems arise, try moving the cables and check the grounding connections.

2.3. Choice of the equipment to which the printer is to be connected The printer must be connected to the Beta90 board of any equipment (Digitex 90, instrumentation) controlled by the Vdtex computer present on the system. The printer cannot be connected to the Vdtex computer. When selecting the equipment to which the printer is to be connected keep in mind that the print-out management module uses the meter counter sensor of the machine on which it is installed. If you wish to obtain a report giving the total no. of meters at the output of the line, it is therefore important to link up to an instrument whose sensor is at the output end (e.g. the reading bridge). Printer enabling by means of the configuration switches (SW1) must be performed only on the Beta90 board to which the printer is connected.

2.4. List of connecting terminals The electrical connection with the protocol converter and hence with the printer is by means of the M3 connector of the C285 board, called Beta90. 3ULQWHU 7HUPLQDO VWULS

2.7. Vdtex computer self-configuration procedure The self-configuration procedure of the Vdtex computer makes it possible to define the number and type of instruments connected. The procedure must be performed each time you change the number of instruments connected to the Vdtex (system expansion or modification). To perform the procedure, it is necessary to know the access code to level 3. • Turn on the Vdtex computer and all the instruments connected to it. • Select the access key setting command.

• Set the access key to level 3 (installation level).

• Select the self-configuration command.

• Wait a few seconds for the completion of the procedure (a progressive number marks the progress of the work).

At the end of the procedure, the upper part of the screen must display all the icons of the instruments connected to the Vdtex. If any of such instruments fail to appear at the end of the procedure, repeat the procedure at least a couple of times and then, if the problem persists, verify the station addresses set and the wiring of the missing instruments. If an instrument does not communicate with the Vdtex it cannot transmit the error messages: the data can be obtained from the display unit of the Beta90 board (see the diagnostic section). See the wiring information of serial connection RS422.

3. USE The following paragraphs illustrate the operation of the print-out management system and the relative controls by means of the Vdtex computer; for the general characteristics of the Vdtex computer, see the manual of the machine in which the printer module is installed.

3.1. General concepts The printing module is able to print out the processing data of all the devices connected to the Vdtex computer. Each instrument has it own printing enable control; only enabled instruments can transmit the data to the print management module. The print manager generates one or more columns of data for each instrument enabled, and therefore the size of the print-out depends on the number of instruments activated (see in the technical data the table listing the max. number of columns printable for each paper format). General print activation is performed by means of the control present on the print management module.

11 Selection of printing mode in groups of meters (PM). When this mode is chosen, the machine prints one line of data only upon reaching of the established number of meters. The number of meters can be set by means of the following control, which can be accessed only with the level 1 (supervisor) access key.

The change of printing mode is possible only when printing is disabled. Selection of the printing mode upon the passing of the set error thresholds (PE). When this mode is selected, the machine prints a line of data whenever the adjustment error exceeds one of the set thresholds. The machine performs an average evaluation of the error for a given number of meters. The number of meters can be set by means of the following command which can be accessed only with the level 1 (supervisor) access key.

The change of printing mode is possible only when printing is disabled. Setting the management data (HD). With this command it proves possible to set the data concerning the process underway. The maximum length admissible for each datum is 20 characters. The management data are printed in the heading of the report. The data introduced are displayed in the central column of the screen and cannot be used immediately by the machine, but are stored until they are activated by means of a special command (see next command). For the character and number setting method, see the “Data setting” chapter. Activation of the data introduced. By means of this command, the data introduced with the previous command (and displayed in the central column of the screen) are activated and are moved to the right hand side column of the screen. The data will be printed the next time the printing report is opened again.

Setting the group of meters for the group of meters (PM) printing mode. The value set cannot be too small in relation to the line speed and the printer’s printing speed so as to enable the printer to finish printing each individual line before the next one arrives. The setting process can be performed only when printing is disabled. Setting the number of meters within which the machine must determine the average of the error. The machine performs an error measurement every meter and therefore, by setting, for instance, 5, we get an average evaluation of the error over 5 readings. The setting process can be performed only when printing is disabled. Setting and changing the headings of the management data (HF). It proves possible to use up to 10 different management data. Unused data are not displayed. The maximum length of each heading is 15 characters. For the character and number setting procedure, see the “Data setting” chapter.

3.8. Printing modes The program has two printing modes: printing by groups of meters and printing upon the passing of the error thresholds. The selection is by means of the following commands: Selection of the printing mode by groups of meter (PM).

Selection of the printing mode based on the passing of the established error threshold (PE). The printing mode can be changed only after closing the printing process by means of the special command. Printing by groups of meter In this printing mode, the program determines (for the number of meters to be grouped) the percentage of fabric belonging to each of the tolerance ranges set. In the print-out obtained it is not possible to determine the exact point where the operation is out of tolerance nor can we establish the mean value and the sign of the error; on the other hand, knowing the length of the piece of fabric we may determine the number of lines in the printed report and the report will be more legible. The number of meters to be grouped can be set. In the example below of printing in groups of 10 m with weft distortion data we find that in the first 10 m 100% of the fabric is in tolerance 1 where both skew and bow distortions are concerned, between the tenth and the twentieth metre skew distortion occurs, so that 90% of the fabric is in tolerance 1 and 10% is in tolerance 2, etc.. The individual lines do not give the sign and mean value of the error, but only the percentage of fabric comprised in the specified tolerance range (to obtain the mean value of the error and its sign, use the printing mode described below). The printing process ends with an indication of the quantity of fabric (as a percentage and in metres) belonging to each tolerance range. Printing based on the passing of the established error threshold In this printing mode, the program prints a line whenever the error shifts from one tolerance range to another (in either direction); the printed line contains the value of the meter counter in which the passing of the tolerance limit has occurred. In this mode it is not possible to know in advance the number of lines that will be printed. The example below illustrates printing based on the passing of the error threshold, and it shows the columns with the weft straightener data; from the example it can be seen that the average skew error was 1.1% (tolerance 2) up to the twentieth metre, then it became 0.8% (tolerance 1) up to the thirty-fifth metre and finally it became negative (-1.2%) up to the forty-fifth metre, and so on. The printing process ends with an indication of the quantity of fabric (as a percentage and in metres) belonging to each tolerance range. Edition: 20/05/1998

4. SERVICE ADJUSTMENTS The only adjustments that can be made concern the number of meters to be grouped (for printing by groups of meters) and the number of meters within which to determine the average error (for printing based on the passing of the error thresholds); the indications are given in the list of level 1 commands. There are no tables of data to be set.

4.1. Setting the tolerance ranges The tolerance ranges (whose values are displayed in the heading of the print-out) must be set by means of the control panel of each individual instrument enabled for printing: for the information, refer to the description of the KS parameters of each instrument.

1- Standard configuration: 1.1- System configurations:

The VDTEX computer can be supplied in a single version suitable for installation on a revolving support or panel-mounting:

The data entry device consists of a membrane keypad and a resistive or capacitive touch screen. The components adopted for these computers are all of industrial type, the degree of protection on the front is IP65, there are no moving parts subjected to wear (such as hard disks) and the data are displayed on a last generation TFT colour screen. 1.2- Software configurations: The VDTEX computer can be equipped with two different types of software, depending on the machine you want to connect it to: 1. Software PROCES PC10 2. Software VDTEX96 SW PROCES PC10 makes it possible to control BIANCO machines fitted with DIGITEX 180electronic components and meant for this use. This SW is supplied only with VDTEX computers fitted with a keyboard, since it does not support the touch screen. SW VDTEX96 represents the evolution of PROCES PC10, and it makes it possible to control BIANCO machines using DIGITEX STD1 electronic components. This SW can be supplied with all VDTEX computer versions.

3- Use of VDTEX96 software: 3.1- Using the touch screen SW VDTEX96 recognises and manages the touch screen automatically. To activate a control by means of the touch screen just touch the screen, applying a slight pressure to the icon symbolising the control itself. By means of the touch screen you can also enter numerical values, when this type of entry is required: just press, on the screen, the value that you want to modify and a small numerical pad will appear, with digits 0 to 9 plus a number of function keys. If you press the screen outside the pad area or confirm the data entered by means of ENTER, the pad disappears. If you make changes to the values listed in the (KM, KT, etc…) tables, without the aid of the keyboard, it is possible to move from one field to the next by causing the small numerical pad to appear and then use the arrow keys displayed in the latter. We give below a few examples of views partly covered by the numerical pad:

3.2- General characteristics The figure below illustrates the front panel of the VDTEX computer. The indications provided also apply to the touch screen version. The display can show the data in full or half screen mode; the half screen mode is used when the VDTEX is connected to 2 or more instruments or machines so as to be able to display two display windows at the same time. A list of the machines or instruments connected to the VDTEX is provided by the set of icons aligned in the upper part of the screen. Each icon shows the instrument's identification number: to recall an instrument, just type the relative number via the keyboard or touch the icon on the touch screen. In half screen mode, the instrument recalled will appear in the bottom part of the screen. By means of the keyboard you can shift from half to full screen display mode, or vice versa, using the up/down arrow keys. To enlarge or reduce the display by means of the touch screen, instead, just press the icon of the machine in the top left corner of the screen. The lower part of the screen shows the main commands and the operating status of the instrument or machine. In half screen mode, you can activate the controls of the instrument displayed in the lower part of the screen. To cause an instrument to be displayed in the lower part, just press the corresponding identification number or press the relative icon, which can be found in the top first line of the screen.

Activates a terminal emulation program: this function is meant for service technicians testing the functionality of the electronic boards of the machines. The emulation program makes it possible to set the serial communication parameters (baud rate, parity, number of bits, stop number); it can be quit by pressing the ESC key once or twice. When you quit this program, the main menu reappears. The combination is used to check the integrity of a floppy disk with the upgrade of SW VDTEX96. This function is reserved to service technicians and it works only after connecting a floppy driver to the VDTEX. Accordingly, in a VDTEX in normal configuration it has no effects. This function is not described in the menu. Pressing these keys resets the VDTEX96 data access keys to the factory values. It is used when a user changes the keys and loses the new codes. Resetting is accomplished without any message and remains displayed in the menu. You are asked to enter the current date and time, then the main menu is restored. This function is used to update the system clock, even if the latter is not going to be used or displayed by the SW VDTEX96. An ancillary menu is displayed:

at this point, press SHIFT+A to set the serial line towards the machine for a baud rate of 9600 baud, or press SHIFT+B to set it at a baud rate of 19200 baud. The setting process does not display any message. Press the combination of keys SHIFT+C to return to the main menu. Note: The baud rate must be selected as a function of the setting of this value on the machines to which the VDTEX is connected. If the VDTEX is sold together with the machine, the baud rate set is already correct. If the VDTEX is sold as a spare, you may have to set the baud rate again.

5- SW upgrade functions. 5.1- Initial installation of the SW. We describe below the procedure to be followed to install the SW in a new VDTEX, or to install it again if the storage disk or the data contained therein have been damaged. First of all, you must have on hand a floppy disk driver, which is not supplied as standard with the VDTEX, a keyboard, for touch screen versions, and the following floppy disks: 1. System reset disk 2. VDTEX96 Ver…program installation disk Proceed as follows: 1. Turn off the VDTEX. 2. Connect the floppy disk driver to the VDTEX; the method of connection will vary depending on the VDTEX version your are using. For this operation, see the documentation attached to the floppy disk driver itself. 3. Introduce the SYSTEM RESET disk into the driver and turn on the VDTEX. 4. Follow the prompts as they appear on the screen (these prompts are not given in this manual, as they may vary depending on the type of system reset disk supplied: at any rate they boil down to pressing certain keys). 5. At some point you will be asked to pull out the SYSTEM RESET floppy disk and to introduce the PROGRAM INSTALLATION disk, then turn off the VDTEX, wait a few seconds and then turn it on again. At this point, the chosen software has been installed: follow the prompts that appear on screen until the final message tells you that the process as been completed. 5.2- Upgrades after the initial installation of the SW. If you are upgrading the SW with a new version, i.e., the VDTEX IS ALREADY OPERATIONAL, you can proceed faster by means of the ancillary functions menu, described in the previous paragraph. Warning

Some or all of the ancillary functions described below may not be missing from the ancillary function menu or your VDTEX. If the upgrade functions are not present, the only way to upgrade the software is apply the procedure explained in the previous subparagraph.

Function activated Makes it possible to modify a recipe or create a new one. The recipe is displayed as a page, in table form. Each page contains all the operating settings of a machine and the number of pages corresponds to the number of machines connected to the VDTEX. The tables with the recipes can be modified in the same way as a normal table (for instance, table KM), as described in the relative section. The difference is that in lieu of descriptions, the different lines contain icons illustrating the parameter. For further details, see below subparagraph “Recipe tables”. Makes it possible to recall a recipe created previously. You are asked to enter a recipe code. If the recipes have been configured from BIU (see recipe configuration section) the recipe code remains available for the PC, or the PLC, which can read it and transmit the relative data. If the recipes have been configured from the disk, the file with the same name as the recipe code introduced is sought, and it this search does not succeed, the operator is warned by an error box. This is used to save a modified or a newly created recipe. If it is a new recipe, you are asked to enter a code. The recipe is saved in a file with the same name as the code entered; if the file cannot be saved, the operator is warned by means of an error box. N.B.: This command appears only if the recipes have been configured from the disk. Transmits the recipe to the machines. The different settings are transmitted to machines. The settings transmitted to a machine that is not ON are lost (if the machine is turned on when the recipe has been transmitted, it will be necessary to transmit the recipe again to set the machine).

C.2- Configuration methods As discussed above, it is possible to configure the recipes for management purposes by means of the BIU board (command ) or to save the data on the disk (command ). In the subparagraphs that follow, we shall examine different operating modes for the two types of configuration.

VDTEX HG 2005_E

R

S.p.A.

VDTEX User's Manual Page 35 of 41

C.2.1- Configuration for the management of recipes on disk. In this case, the codes entered, for recipe reading or saving, must be valid file names since they are going to b used, with extension “.RIC”, to have access to the files and either read the recipe from them or write the recipes onto them. The path giving access to such files is saved in a special file “VDTEX.MES” and cannot be easily changed by the user. By default, this path points to a special directory residing in the local disk of the VDTEX computer. If it proves necessary to connect the VDTEX computer to the network, to manage the recipes on a remote disk, contact the BIANCO service and supply indications on the type of network you want to connect to and the type of connection to be established, as well as the path to be introduced into the “VDTEX.MES” file. C.2.2- Recipe management by means of BIU90 option. By means of the different versions of the BIU90 option (see specific documentation) it is possible to connect all BIANCO machines, that are pre-set and present on a line, either to a PLC or to a remote PC. This BIU enables the recipes to managed from a remote unit in different ways: 1. The remote PC (or PLC) manages the recipes independently and, through the BIU, sets the various machines; in this case, the VDTEX management function is not exploited and the VDTEX is used solely as a local control station. 2. The VDTEX is set for recipe management through the BIU. The recipe code is entered via the VDTEX, which is read by the remote PC (or PLC); the various machines are set by the PC (or PLC), and the settings are displayed on the VDTEX too. 3. Same as at point 2, save that the settings are displayed on the VDTEX but are not transmitted to the machines: through the VDTEX you can see them, modify them as necessary, and then transmit the to the machines when the fabric begins to be processes. The types of management described above are the most common, but there are variants that can be introduced such as the transmission of a recipe from a remote PC (or PLC) depending on the action of an external device, connected to such units, without having to enter the code via the VDTEX, and so on. For a detailed description of the possibilities offered by the various optional models of BIU90, see the relative documentation. C.3- Colours of the recipe icons. After the configuration, the top line of the VDTEX screen shows the recipe symbol ( ), which can take on 4 different colours, with the following meanings: white red
