Connect EARTH terminal to closer grounding in case Pitagora instrument is powered by power supply generator that is separated from the other generators of the application. Analog outputs, RS232, RS485 etc of Pitagora are all grounded: be careful not to have ground loops. It is advisable that all power supply negative (GND) connections are referred to the same earth connection for the whole machinery. Electrical signal cables are not to be cabled together with power cables. In case of low electrical noise environments this connection can be avoided.

The resistance is to be 120 Ohm, ¼ watt. This resistance is to be applied only on the last connected instrument, in order not to lower too much the overall line impedance (figure 11 ). fig. 11 : Multi-drop connection of several instruments. 3 Menu setting – general sequence This chapter describes the procedure to set instrument’s working parameters. This sequence is valid for all the instrument’s menus. ▼ ▲ E C Down arrow: It allows to scroll all the possible choices of a menu or to decrease a parameter’s value. Up arrow: It allows to scroll all the possible choices of a menu or to increase a parameter’s value. Enter: It confirms modified parameter and stores the value on the instrument. ESC: It allows to exit from a menu without confirming any change to the parameter’s value or to zero (dynamic zero) the value shown on display when Pitagora is in normal working status. Pitagora instruction manual V1 r 19 - 31/01/07 -15These push buttons can have additional functions, depending on the chosen operating modality. Push button can be damaged, if sharp objects are applied (screwdrivers or similar). By keeping pressed the E button, when modifying a parameter, allows to show on display (prior to the button release) the numeric index corresponding to the parameter (i.e.: P03501). The index can be used to modify the parameter by means of digital serial communication. 5 2 4 1 3 4 Display Pitagora instrument is has an LCD display, with backlight, able to show the following data: 1. Main 7 alphanumeric digits display, 8 segments, plus polarity able to display numbers up to ± 9999999 or words (capital or small letters). 2. Secondary display, with 14 alphanumeric digits, used to show information referable to the measured value displayed on the main displayed or used to provide additional indications during instrument customization. 3. Bar display, with central zero, to display the behaviour of the measured value. 4. MENU indication, active when Pitagora instrument is used during Customization procedure with a numeric value that indicates the active personalization level. 5. Serial communication and data transfer activity. When Pitagora instrument is switched on it will show, in sequence, the following information: 1. Pitagora Name of instrument 2. Pt 401 Hardware version 3. V 1.00 Installed firmware version 4. SN. X Serial number of instrument 5. MD 1 Active measurement modality Pitagora instruction manual V1 r 19 - 31/01/07 -16- 5 Instrument setting Personalization menu is protected against unwanted accesses. Switch on the instrument, keeping pressed at the same time ▲ and C push buttons. Instrument will allow to setup the card eventually installed into slot A. SLSET will confirm on the display that personalization menu is active (SLot SETup). “MENU 1-” indicates that setup procedure for the chosen card is on the topmost level of the main personalization menu. When push button are released display shows on upper alphanumeric line the type of menu (SLOT SETUP); main display line indicates the name of the installed card to be customized. Firmware uses the following syntaxes, when setting card parameters: 1. Slot reference: a letter, followed by a decimal point, to indicate the reference position of the card installed on the instrument (real card) or to indicate virtual card reference. 2. Function/parameter reference: 3 or more letters that identify the function/parameter to be set. If an A/D card (mod. I4) is installed in slot C, setup menu will refer to It as C.AdC (C. to indicate slot number = C; AdC to indicate card type = A/D converter); B.AdC indicates that an A/D card is installed on slot B. The following type of cards may be considered by Pitagora instrument: • Real card: cards installed on slots from A to D, on the rear of the instrument. • Virtual: are peripherals applied in the instrument, like serial communication ports or like functions that allow to perform calculus, alarm levels that will activate relays outputs or will send status messages through serial connection or complex functions like P.I.D or softP.L.C. etc. Menu structure, used to configure the Pitagora instrument, will be defined by the position and type of active cards on the instrument. Menu parameters can be set in the following ways: Prefix Menu parameter Card setting A letter, used to identify: Corresponding function or feature > the card slot, on the rear of the LEV indicates the alarm levels. instrument > a virtual card C. for slot number C H. for virtual slot number H Channel A number, to identify the channel of the Corresponding function or feature setting card (I/O cards with several VLO, to display the LO parameter. inputs/outputs) Available sub menus, for each card, can be accessed by pressing E push button. To return to the main menu from a sub menu, press C button. Pitagora instruction manual V1 r 19 - 31/01/07 -17- Example: menu structure of an instrument so configured: Slot A (physical) = mod. D0 or D1 relay card. Slot B (physical) = empty. Slot C (physical) = I1 or I4 input card, with A/D converter. Slot D (physical) = O2 analog output card. Slot F (virtual) = Modbus digital output. Slot H (virtual) = alarm level By pressing C pushbutton Pitagora instrument exits customization menu entering into normal measure modality, after having saved parameter (SAVE is displayed) and after a software reset. Menu structure: this customization menu structure is dynamic as It depends from the type and position of the installed hardware cards and is supplied just as example. NUL, with the reference of the selected slot, will be shown (example: b.nul) if no physical card is installed on the selected slot or if no virtual function is available. Pitagora instruction manual V1 r 19 - 31/01/07 -18- 6 AdC setting (I1 or I4 input cards) This menu allows to set the working parameters of any card with A/D converter. It is possible to set the behaviour of one or two A/D converter parameters, allowing the conversion of the measured voltage signals into the chosen engineering units. In order to convert measurements into displayed numeric values in engineering units Pitagora need to store two measured voltage signals, to be associated with the corresponding known values in the desired engineering units. Hereafter is indicated the sequence that allows to set the A/D parameters of an input channel. A/D channels are identified by a numeric index, displayed as prefix of the parameter to be set. • Channel A/D 0 (CH0) = setting of parameters 0.AdSP, 0.VLo, 0.VHI, 0.VtAr, 0,PSdP Transducer connected to this channel is identified as Bridge 1 • Channel A/D 1 (CH1) = setting of parameters 1.AdSP, 1.VLo, 1.VHI, 1.VtAr, 1,PSdP Transducer connected to this channel is identified as Bridge 2 When a new parameter is set and stored, by keeping pressed E push button, a numeric index is shown prior the release of the push button (i.e. P03501), to indicate the parameter’s reference. This index reference is useful when Modbus serial utility is used, as it allows an easy understanding of the parameter’s dictionary to be used with a remote connection (serial connection) allowing an advanced use of the unit. Pitagora instruction manual V1 r 19 - 31/01/07 -19- Pitagora instruction manual V1 r 19 - 31/01/07 -20The indicated A/D converter setup structure applies to channel 0 and channel 1 of a two channel A/D input card. A multi channel Pitagora unit, with two I4 input cards, will have the following parameters to be set: Slot (example) Type of setting Available channels Settings B B.AdC Ch0 0.AdSP 0.VLo 0.VHI 0.VTar 0.PSdP CH1 1.AdSP 1.VLo 1.VHI 1.VTar 1.PSdP C C.AdC Ch0 0.AdSP 0.VLo 0.VHI 0.VTar 0.PSdP CH1 1.AdSP 1.VLo 1.VHI 1.VTar 1.PSdP It is important to note that the AdSP settings for a summing unit are to be the same for all the channels, so that the result of the sum is obtained using measurements that can be related each other on a time basis. Cont (Continuous) parameter allows to set the instrument in order to: Cont = 0 Pitagora samples values from channels CH0 and CH1, from selected A/D converter. Cont = 1 Pitagora samples data solely from CH0, from selected A/D converter. AdSP value, for single channel 0 1 2 3 4 5 6 7 8 9 Continuous = 1 Continuous = 0 3840 1920 960 480 240 120 60 30 15 7.5 Hz Hz Hz Hz Hz Hz Hz Hz Hz Hz 320 160 80 40 20 10 5 2.5 1.25 0.625 Hz Hz Hz Hz Hz Hz Hz Hz Hz Hz Note for AdSP setting: the parameter sets the update rate of the measurements provided by the A/D converter with reference to the corresponding measurement resolution. Sampling rate and resolution are inversely proportional: increasing the frequency rate will correspond to a decrease of the available measurement resolution. This is a consequence of the fact that by increasing the frequency rate the A/D converter will reduce the filtering on the input signal so that more noise will be sampled and measurement will consequently be less stable than one obtainable with a lower frequency rate. This behaviour is typical of the used Sigma Delta A/D converter and has not to be considered as a defect.

It is herewith described the procedure to set the parameters of alarm level 0 and this procedure can be used for all the other available alarm levels (0.LEV, 0.HYST, 1.LEV, 1.HYST, etc.) The parameters to be set are to be entered as integer number, without any decimal point, using the same number resolution considered when A/D converter calibration parameters have been entered for input cards setup (Example: if I1 input card has 0.VLO and 0.VHI values expressed with grams resolution, then also 0.LEV has to be set with the same grams resolution, without decimal point). l Card A Relays RL2 A RL3 B RL0 B RL1 Pitagora instruction manual V1 r 19 - 31/01/07 Parameters 0.LEV 0.HYST 1.LEV 1.HYST 2.LEV 2.HYST 3.LEV 3.HYST -24- 10 MAG setting (I10 Start Stop input card) Pitagora instrument, with installed Start Stop card (I10), allows to acquire measured measurements from a DS Europe linear displacement magnetostrictive transducer. VLO and VHI parameters have to be acquired and stored, by pressing E push buttons, having the transducer’s cursor in the mechanical positions, along the transducer measuring rod, to which it is needed to associate the corresponding position value (expressed in mm, inch or other engineering unit). Pitagora instruction manual V1 r 19 - 31/01/07 -25- 11 LCD display setting If Pitagora instrument has installed an LCD display, it is possible to set background light intensity and contrast, in order to optimize measurement’s readability, accordingly to the ambient light conditions. 12 Return to Measure modality After having completed all settings it is possible to get back to the measurement modality. From the topmost level of the main configuration menu, press C push button. Pitagora instrument saves set parameters, displaying SAVE. A software reset is performed and then current measured value is displayed. Note that all parameters are saved on a EEprom memory to hole them after power off of the instrument. Pitagora instruction manual V1 r 19 - 31/01/07 -26- 13 Introduction to measure modes Pitagora instrument allows a modular configuration of its hardware (input and output cards). Consequently all internal configuration menus and operating measurement capabilities are dynamic and will reflect the existing hardware configuration. Also the available measuring functions will reflect the installed hardware and the internal function configuration performed by DS Europe, prior shipment of the unit, in order to fit different measuring needs. In the following pages are listed some of the most common hardware configurations, matched to their software operating modes. Additional software and hardware configurations can be developed by DS Europe accordingly to Customers’ needs. Virtual channels allow to handle, mathematically, signal values measured by input channels (I cards) through sums, subtractions and all most common mathematic operators. For multi channel configurations it is possible to change the sequence used to display data or to transmit their values by digital connections to remote devices, using instrument’s internal communication ports. All the listed measurement modes are to be considered as a reference for order definition, since instrument is configured in our Factory, as hardware and function configuration, accordingly to Customer’s needs, so to simplify the installation and use of the unit. DS Europe is ready to develop additional measurement modes that may be needed by Customer for their measurement purposes, starting form one of the existing measurement modes, considering all possible mixes of hardware input/output cards, measurement functions or data displaying required. In order to develop a new measurement mode for a new application, we need a detailed description of the behaviour required from the measurement system, considering the technical characteristics of the different I/O cards that can be installed on the unit. New I/O cards can be developed. On the following modes the Measure table indicates all the available measurements performed by the instrument, that can be displayed in the indicated sequence. When several measurement are available press the  pushbutton to obtain the required measurement value, indicated on the LCD display by the corresponding labels that appears on the secondary display. Displayed measurement are shown using a closed loop display sequence. Example: with a 3 channel summing unit, as for MD = 2, displayed powered on is NET SUM.

I10 (Start-Stop) input card for DS Europe magnetostrictive position transducers model PCS /PCR LCD display Secondary display Main display 123.4 MM -12345 Shows the displacement measured by DS Europe displacement transducer model PCS / PCR, with 0,1 mm resolution. It is possible to set engineering units different from “mm” (4 characters, by serial communication). It shows the tension / compression force measured by the DS Europe load cell. It is possible to set Kg or Newton engineering units. Calibration procedure of sample breaking test modality Calibration procedure of the input card (I10) for magnetostrictive transducer is similar to that one of the connected load cell ADC card (model I1 or I4 input cards). To convert the measurement from magnetostrictive transducer Pitagora needs to store the measures (LO and HI) to be associated with the chosen point of Zero (VLO) and Full Scale (VHI) on transducer’s measuring rod, expressed in the engineering units and resolution required. For magnetostrictive transducers model PCS or PCR, VLO and VHI values have to be entered with 0,1 mm resolution. Secondary display indicates displacement measurement having a fixed position for decimal point, accordingly to 0,1 mm resolution. Display could eventually show other types of engineering units as set during the calibration procedure. To enter into the calibration procedure, while powering on the instrument, keep pressed push buttons ▼ and C on the front panel.
