EV 20036.6General dataOn your terminal it is possible to control some functions which can make theinstrument use easier.The functions and their correct use are described below.6.6.1Progressive numberThe “EV 2003” terminal controls a progressive number of max. six digitswhich allows the executed weighing operations to be counted: this valuestarts from the unit and is automatically increased by "1" (one) after anyprinting.So it indicates the value that will appear in the next printing.To detect the value press the key and the"LCD" display will show the writing “progressive”and then the numeric value that will be printed inthe next printing.Progressive 4In the example, the present value of the progressivenumber is “4”.To change this value, follow the procedure below considering that:the progressive number can only be modified with the key selector “1”,placed on the back of the instrument, in position “I”, see fig. 6.6.1.fig. 6.6.1 -key selectorOperation1 - Press the key of the progressive numberand the display shows the writing "progressive"followed by the present value.2 - By means of the numeric keys enter the newvalue of the progressive number.In our example the value “50”.Displayed valueProgressive 4Progressive 503 - Then press the key for value acquisition.-49-

EV 2003Note:after setting the progressive number = 0 (zero),this is no longer increased and disappears fromthe printing data.Its maximum value is 999999.Once this value has been reached, the numberingre-starts from the value “1”.6.6.2Generic codeIt is an alpha-numeric value consisting of max. six digits, which is printed withthe weight data and can be used as a generic code whose meaning must begiven by the operator.After entering a certain value, the terminal will continue printing it for all thefollowing weighing operations, without changing its value.The operator has to intervene for changing it.Press the key .The display will show the words “generic code” and the relevant value thatwill be always printed.To change this value observe the following procedure:Operation1 - Press the key of the generic code and, onthe "LCD" display, the words “generic code”and the code present in the memory willappear.Displayed valueGeneric code A282 - By means of the alpha-numeric keys enterthe new value of the generic code consistingof max. six characters. In our example “B52”.3 - Then press the key for value acquisition.Generic codeB52Note:setting the value of the generic code = spacethis is no longer printed or used for thetotalization.-50-

EV 20036.6.3Dateand timeInside the terminal there is a clock with date indication which is operatingeven when the instrument is switched off for max. two months.This is due to an emergency power supply unit.Both date and time are printed with the weight and the total amounts.To display date and time press the key andthe display will show the date values expressed in“day, month, year” and then the time expressed in“hours, minutes, seconds”.Date 07/04/94 Time15:43:316.6.4Correctionof dateand timeWhen you need to change the time or date values just act as follows:Operation1 - Switch the terminal on by pressing the key.

EV 20036.8Printingof the weighingdataThe weighing data printing consists in two different operations and, consequently,different use of the keyboard.To know the configuration type of your terminal just press the keydata recall:for- if the display shows no variation, the operation is on single weighing;- if “rcd” or “1 weight” is displayed, the terminal is preset for the doubleweighing operation.Note:during the weight printing the display and thekeyboard are locked.When the printing key is pressed, if the weightresults to be unstable, the terminal stores therequest waiting for the weight to become stable.After a few seconds, if theinstrument has not becomestable, the weight isnot printed and the message“Unstable weight"Unstable weightappears.When the printing key ispressed, if the label is notcorrectly inserted, themessage “Insert new label”appears.Insert new labelIf the label is correctly positioned before themessage disappears, the printing occurs automatically.Otherwise press the printing key again.6.8.1Printing with operationon single weighing“Operation on single weighing” means that all weight values (gross, netweight and tare) are reported on single printing.The data concerning the weighing operation in progress can be printed-57-

EV 2003pressing the key: the printing request is accepted only if:- the weight is stable;- the weight is not negative or higher than the maximum capacity;- the weight is higher than the minimum weighing.Before printing the terminal checks if there is paper:- for a label printer, the presence of the label on the plate is checked;- for a Z-fold printer it is checked that there is still enough paper. Otherwisethe terminal ignores the printing instruction.An example of single printing on label is given below:NOTESDate 20/12/91 Time 10:28:43Progressive 26Progressive no. ofweighingsGROSSTARENET17380 kg10000 kg7380 kgfig. 6.8.1 - example of label printingIf one or more data controlled by the terminal have to appear on the printing,they should be set.In particular, it is possible to set:- the generic code (see par. 6.6.2);- the product code (see par. 6.7.1);- the coefficient (see par. 6.6.5).Finally, press the printing key and a single printing with all the set datawill appear (see example in fig. 6.8.2).-58-

EV 20036.9Totalization andsummary printingcontrolThe terminal can control different totalization forms depending on the user'srequirements; the totalization always occurs after printing and the summedupvalues are those reported in the printing. Thus, if the totalization optionis enabled, to print the exact totalization values it is absolutely necessary touse both the product code and the generic code correctly. All totalizationforms given below are independent and can be used at the same time.During a weighing operation, if a failure of the printer occurs, the totalizationis not executed; in this case, probably the operator will repeat the printingoperation. The terminal controls and can print 4 totalization types and threesummary printing types, i.e.:1 - Grand total2 - Subtotal3 - Total for product code4 - Total for generic code (if enabled)5 - Product description printing6 - Pre-determinate tare printing7 - RcD and pre-determinate weight printing.6.9.1How to ask for theprinting of the totals orof the product code listTo print the data of one of the available totalizations or of the summaryprintings operate as follows:1 - press the key and the display will showa message consisting of a number and theindication of a total printing or summary printing;**** TOTALS ***1) Grand total2 - by means of the key it is possible to choose among the differenttotal amounts;3 - press the key for confirmation.At this point there are two possibilities:A) if a grand total or a subtotal has been selected: the required total is printed.B) If the total for product code or the total for generic code (if enabled) orthe summary printing of the descriptions for product code has beenselected:the procedure is described in the following example.1 - The display shows the message "from code"and waits for the code number from which itbegins to print.The value of the present code is proposed.Change through the numeric keys and pressthe key , or press the key to confirmthe proposed code.**** TOTALS ***3) Total for prod. code3) Total for prod. codeFrom product code A28-68-

EV 20036.9.11Short procedure forprinting the totalsAny kind of total that can be printed like any other summary printing can bequickly recalled by pressing the key of printing requestand then theassociated numeric key.The list is given below:CodeDescription1 Grand total2 Subtotal3 Total for product code4 Total for generic code5 Description printing6 Pre-determinate tare printing7 RCD and pre-determinate weight printingAfter selecting the kind of total or printing concerned, just press the keyto confirm.If the request concerns the code “3, 4, 5, 6, 7” the terminal will ask for thearea of printing start and end.In these cases, proceed as described in par. 6.9.6.6.10OptionalfunctionsThe terminal operations described in the list below are optional, as they areenabled only upon request by the customer (before the installation).They are:1 - Pre-determinate tare (only for single weighing operation):- tare storing and change;- recall on display;- tare deletion;- self-deletion when unloading.2 - Pre-determinate weight (only for double weighing operation);- weight storing and change;- recall on display.3 - Coefficient associated to the product code (only for single weighingoperation):- coefficient setting and change;- change of the product code being used;- display of the coefficient being used and relevant result;- display of the description associated to the product code being used;- deletion of the description or of the coefficient associated to theproduct code.Their correct use is explained hereinafter.-81-

EV 20036.10.1Pre-determinate tare(only for single weighingoperation)On the “EV 2003” terminal it is possible to associate numeric codes to thesame number of tare values.Thus, you only have to recall a certain code so that the associated tare valuebecomes the tare of the weighing terminal.Once this pre-determinate tare value has been recalled, the display willshow the net weight with the symbols and “NET” (see the nextexample).This operation type results to be similar to the operation with preset tare.The only difference consists in the possibility of storing the tare valuescombining them with numeric codes, in order to make the recall operationeasier.Note:- the set tare value is automatically rounded tothe weighing interval of the terminal.- The set tare value must not exceed the maximumcapacity of the instrument.When the operation with unlocked tare is selected,in order to recall a pre-determinate tare thebalance must be loaded, neither on 0 nor negative.The number of tares that can be stored dependson the terminal programming.- For the “EV 2003 MD” (multi-interval) terminals,the maximum tare value is defined by the maximumcapacity of the first weighing extension(max 1). For the value indicated on the platewith the metrological data of the instrument seepar. 1.4.Thus, only for the “EV 2003 MD” (multi-interval)terminals, if a pre-determinate tare is recalledthe weight display re-starts using the lowerinterval.On the contrary, for the “EV 2003 ME” (multiextension)terminals the display of the net weightwill be the one related to the range of the grossweight.-82-

EV 20036.10.7Pre-determinate weight(only for doubleweighing operation)To make the weighing operations of the instrument with double weighingfaster, it is possible to store weight values that can be recalled several timesthrough a code without repeating the first weighing (for example the tarevalue of a vehicle that must be weighed several times with different loads).For this purpose, data recall registers similar to those used for storing thedata of the first weighing are used; the difference is only the fact that, in theregisters, the data cannot be set and after the output printing they aredeleted in order to be used again.Besides the weight value, it is also possible to store a series of general dataof the instrument, such as the product code and the generic code, in orderto make the weighing and totalization operations easier.The use of pre-determinate weights does not affect the standard input/output weighing operation of the terminal.While customizing the instrument, indicate which data recall codes areenabled to be used for this purpose.Therefore, if you require the output printing after recalling a pre-determinateweight, you will obtain a complete printing, i.e. with a first weighing wherethe pre-determinate weight appears, followed by the second weighingwhere the gross and the net weights of the mass on the instrument appear.6.10.8How to store and tochange apre-determinateweightA storing procedure of a pre-determinate weight is given below:OperationDisplayed value1 - Press the key and the display shows thelast entered data recall code.RcD 0 0RcD 02 - Through the keypad enter the data recallcode to which the value of the pre-determinateweight has to be combined (e.g.: 1).RcD 0 0RcD 13 - Press the confirmation key and the displayindicates the last entered value of predeterminateweight (e.g.: 0).4 - Through the keypad enter the pre-determinateweight value (e.g.: 10000).This must not exceed the maximum capacityof the instrument.RcD 1 0Pre-determinate weight 0RcD 1 0Pre-determinate weight10000-87-

EV 20039 Maintenance9.1IntroductionDANGER!!Any cleaning and maintenance intervention mustbe executed with the terminal disconnected fromthe power supply line.To guarantee constant and proper operation of the terminal and to preventthe guarantee from being null, any part replacement must be performedexclusively with original spare parts. Only technicians who have beenexpressly authorized by Coop. Bilanciai have to care for the maintenance.WARNINGThe data on the plate, the closing and certifyingseals of the terminal must no way be modified orremoved.If they are impaired or removed, the guaranteeimmediately falls off and the manufacturer is nolonger responsible for any material and economicdamage.9.2Checks performedin Coop. BilanciaiworksThe weighing system you purchased has been carefully tested andchecked in our works in order to be properly set in every part (platform,electronic terminal), in accordance with the metric regulations.-149-

EV 20039.3Checks to beperformed duringinstallationWhen installing the terminal, to check that it has not been damaged duringtransport, carefully perform the checks listed below:- make sure the power supply voltage corresponds to that of the terminal.- Check the presence and the integrity of the warning and danger plates andthat containing all identification data of the instrument.- Check the integrity of the front panel, the electronic component case andthe rear connectors, as an incorrect transport might have damaged them.- Test the operation in order to check the integrity and the correct working ofall inner components of the terminal and the integrity of the luminoussegments of the display.9.4Periodical checksBesides what above described, make regular checks on the basis ofthe indicated terms.Before every working shift- Check the perfect operation of the display segments pressing the key .Periodically- Check the correct power supply- Check the integrity of all the keys of the terminal and of the connectingcables to the external devices.- Check the correct weight display with known weights. The term variesdepending on the use frequency of the weighing system.9.5How to performthe requiredchecksBesides the periodical checks the electronic terminal does not needparticular maintenance operations; however, for cleaning the painted orplastic parts do use a wet cloth with a non-toxic, non-corrosive and nonabrasivecleaning agent.-150-
