This equipment has been projected for the surface measurement of finished skins with maximum measurable thickness of 6,2 mm and maximum surface of 999 dm². Proper data processing allow to manage the acquired data in order to make the system to be adaptable to the specific working requirements and to obtain exact information regarding the skins’ data. This apparatus is therefore destined to those firms t hat they have necessity of measure the surface of the skins having a complete series of precise data like final result it i s on the number that on the surface of each lot of skins.
4.2
REQUIRED PARTICULARITY Being the method of skin transversal reading based on the principle of the bright beams infrared rays interruption placed at 20 mm one by one by the skin, is necessary that the same is able t o interrupt the beam of light. The 'read' surface is, however, produced by the skin projection on the photocell bar during the crossing in the reading group; if, for example, the skin has one side refolded on one self, the relieved area will be small than the real one.
4.3
PERFORMANCE As it consists basically of a microprocessor-controlled computer, the system is exploited via its software capacities. Features: Automatic or manual totals with: number of hides and total surface. Memorization of up to a total of 16 million hides. Signaling of errors automatically with acoustic warnings and display of m essages. Semiautomatic control of peripherals (printer, display, etc.). Setting of data relating to the batch of hides to be measured (article, color, etc.). In addition, the system is provided with: Memory retention in the event of accidental power cut-off 58 key keyboard with liquid crystal 80 character display High intensity illuminated display of the hide surface For the specific commands and use of the keyboard, refer to chapter “Key board use” of this manual.
4.4
APPLICATION LIMITS The morphological characteristics of the hide are the main limitation to use of this equipment; it is however necessary that it is not transparent, that the thickness doesn't overcome the 6 mm around and that the rigidity is sufficiently low from allow to the same skin of adapt to the surface of the conveyor. The maximum surface area that can be measured is 999 dm² or 99.75 ft².
4.5
WORKING ENVIRONMENT The equipment is made of steel coated in dual-component epoxy paint to provide a high level of resistance to the humidity commonly found inside tanneries. The whole system is constructed so that the electrical parts are protected from the water except for the printer - here particular care must be taken as water can enter the computer via the paper tear-off device. The system is protected to IP40.
AVOID USING JETS OF WATER NEAR THE SYSTEM. Environmental characteristics: The operating temperature can vary from 0°C to 45°C. Maximum relative humidity permitted is 80% from 0 to +30°C, dropping to 65% at temperatures between +30°C and +45°C. The maximum altitude at which the system can operate must not exceed 1,500 metres.

INCORRECT USE Correct installation of the system and specific application limit the possibility of incorrect use which in any case is confined to incorrect installation or incorrect programming of the surface calculation parameters (see chapter 7). If the measuring machine is not operating, avoid using the conveyor for depositing hides or wooden pallets which can weaken the mechanical structure. For the same reason you are advised not to measure rigid material weighing over 80 kg and/or thick than 10 mm.
4.7
CHECK MEASURE In equipment the machine has furnished a caliber sample realized in cloth polyester with circular form and with surface of 65.0 dm². This caliber is definite "disk sample" since his surface has an excellent stability both at the traction and at the temperature. Is important verify at least once the day the correctness of the machine's measure. Consult the normative ISO 11646 of the 1993 for the procedure of inspection measure. Considering that the resolution of measure machine is tenth of square decimeter (dm²/ 10), the GER ELETTRONICA, in each case, suggests to proceed like follows: Recall the screen "Q1" and set the measure unit in dm²/10 (" C.MEAS.= 5"); Recall the screen "Q2" and set 10 the number of skins for package (" PRE-SELET1= 10"); Introduce the disk sample on the left side of the machine. The disk sample must be leaned against on the skin introduction bench with the shinier side turned toward the bottom and introduced under the measure wheels. Ev en if it doesn't provoke remarkable variations, don't hold back the disk sample; it must be lets to flow during the measurement. Verifies that, during the measurement of his central portion, doesn't get out of the external profile of the measure front . Check the measure on the display that m ust be inside the lower limit of 64.6 dm² and the superior one of 65.4 dm² (64,6

INSTALLING THE MEASURING MACHINE
6.1
PACKAGE The measuring machine construct by GER Elettronica S.r.l., could be sends gets off or already assembles (depends by dimensions), according to the destination and by contractual specific accords.
6.2
TRANSPORT AND RELOCATION IMPORTANT:
6.3
Is recommended that the unloading from the truck has made lifting the machine with carts elevators introduced in the apposite centers marks from this symbol. When is necessary shift the machine inside of the building, always proceed and in each case, lifting the machine on the marked supports. If for reasons of space is necessary often proceed at the relocation of the machine, is opportune supply to apply the self a system of support wheels with brake that could be furnished by GER ELETTRONICA.
POSITIONING The measuring machine must be positioned so that there is sufficient space at the outlet to easily distribute the hides on the pallet. If possible avoid places very near to the drums as the m achine could be subject to a high level of chemical aggression. Also avoid areas which are sometimes sprayed with water or near systems which are washed with pressurized water. If this is not possible, extreme care must be taken not to expose the parts of the measuring machine (especially the printer) to jets of water (or other) under pressure (e.g. hydro cleaners). The LOTO box must be positioned beside the measuring machine on the side which is best protected both from collisions with forklift trucks and jets of water. Despite a method of reading at modulated light allows to filter the light environment, is opportune avoid that the reading bar results illuminated by solar light or by lamps (neon) that would can, in extreme cases, preclude the functioning of the measuring machine.
6.4
ELECTRICAL CONNECTIONS The main part of the system is the LOTO box where all the signals and power supplies arrive and depart. Figures H and D show the main connections of the peripherals to the LOTO box. Fit the connector block to the left of the machine and identify the connection cables by means of the following: 1st Connect the receiver bar. Connect the 9-way connector ; 2nd Connect the projector bar with the two wires “21” and “19” ; 3rd Connect the encoder wheel cable. The aim is to ensure that the magnetic sensor fitted on the side of the speed detection wheel (figure A ref. 1) transmits to the LOTO box an impulse approximately every 10 mm of hide feed. The front of the control box features a red led marked CONV which lights up when the metal part of the encoder disk (die-cast inside) is in front of the sensor head. This type of sensor has a maximum detection distance of 2 mm and must therefore be regulated, to ensure correct operation, at 1 mm from the encoder wheel. The LOTO box controls both impulse edges thus obtaining reading of the photocell bar every 10 mm of hide feed. Fix the position of the sensor by tightening the jam nut and check, by rotating the encoder wheel manually, that the “CONV” led blinks regularly. BLINKING OF THIS LED IS IMPORTANT FOR OPERATION OF THE EQUIPMENT. 4th Link up the cable of the stamper. If inserted already into the chain plastic guide-threads, fix the chain either at the cart of the stamper since a side as at the beam since the other. In the case that the chain has already fixed, insert the cable of the stamper after have completely wide (without curves) the chain self. 5th Connect the emergency button cable. 6th Connect the motor cable. 7th Connect the power supply cable entering the LOTO box support. The electrical connection is made via the terminals in the support. Check that the machine power supply voltage corresponds to the factory power supply voltage. For connection to the power supply line, use 4x1.5 mm² NPI cable. If the distance exceeds 10 meters or if the cable runs alongside other motor power supply cables (especially if controlled by drives) you are advised to use 4x1.5 mm² shielded-conductor cable.

SWITCHING THE EQUIPMENT ON Set the ‘MAIN BREAKER’ to position “1” (A) and press the button of "MAIN PUSH BUTTON" (B): the LOTO box acoustic warning signal emits two brief sounds, the monitor comes on showing the operating screen and the 3 leds signaling +24 +12 and +5 should all be on at the same intensity. Press the black button “START MOTOR” (C). The conveyor rotates correctly if the direction shown in figure A is B C observed. If the conveyor does not rotate, check the connection with the emergency button and/or that it is in the released position. If the direction is wrong, disconnect the power supply line and invert the A wires of 2 phases in the motor terminals. At switch-on, the measuring photocells are automatically tested. If some photocells are wrongly illuminated, the acoustic warning signal will indicate this by emitting an intermittent sound for approximately 20 seconds. An error message will also be automatically displayed generally indicating which photocell is not working. The LOTO box is provided with three 1.5V 14x50 alkaline torch batteries. The purpose of these batteries is to retain the data of the hides measured and the working parameters in memory when there is a power failure and the equipment cuts out.
VERY IMPORTANT: With the machine and battery switched off (or with the BATTERY button pressed) for at least 30 seconds, when the measuring machine is powered, the microprocessor performs a TOTAL RESET of the memory and preloads certain parameters which permit the measuring machine to operate. If the battery remains on (with the equipment switched off) when the measuring machine is powered, the microprocessor performs a PARTIAL RESET retaining the measurement data and pre–loaded parameters.
IN THE EVENT OF AN OPERATING FAULT , YOU ARE ADVISED TO PERFORM A
TOTAL MEMORY RESET. 6.6
DISPOSAL IMPORTANT:
If the machine has made over to other user, enclose the existing handbook always. The handbook is considered integral portion of the machine. If the dismantling and the demolition comes effected in proper, divide the materials varieties for typology undertaking afterward, for the disposal, firms authorize for the separate typologies. Proceed like f ollows:
Remove the aluminum plates in of the register and that portions approximately equal.
Report in the manual in proximity of the series number's reference, the date and the place of the happened destruction of the register.
When a temporary period anticipate the destruction of the machine, take off the electric and pneumatic connections and cover the machine with a pack-cloth. Is opportune apply a poster that carries the notice "MACHINE IN DEMOLITION".
The machine has constituted mainly by a metallic painted structure and by electronic cards at semiconductors that don't foresee specific procedures of disposal. In the models with conveyor of transport, is opportune loosen the tension of the conveyor or provide for cutting it transversally. The machines prepared of stamping unit, has air a tank in the regulation's group of about 20 cl oil that must be digested in accordance with the normative national. The type ribbons of the printers, contains ink that must be collected apart and digested in conformity at the in force l aws.

The programming of “Y” or “N” after the unit of measure, allows to enable or not the print the unit of measure on the heading of totals. It is possible to perform exclusively in print phase the conversion of the measurement performed, in a unit of measure different from the one programmed by setting the SECONDARY UNIT OF MEASURE. If it is selected an imperial unit of measure (square feet) it is possible to set the size of a side of the square foot operating on the data FOOT’S AREA; the m easure can be: “30.48 – 30.00 – 28.00”. As on the two previous programming, it is possible to enable or not the print of the value programmed in the heading of the totals. Once the parameter is set, press to exit.

PRESELECTION T1: here it is set the number of the leathers to have the total T1 automatic(from 2 to 1990). NOTICE T1: with this variable you set the intervention of the acoustic signaler according to the number of leathers missing before the closing of the total T1 previously set. if, for example, you set 5, the acoustic signaler shall indicate the end of the total T1 5 measurements before the end of the packet. NUMBER LEATHERS PER LOT: you set a number of leathers ; if it is reached, an acoustic signal is commanded. The count of the leathers is related to the total T2 and T1. LAST T1 CLOSED: You set the number of the last packet closed. Normally the numeration is automatic; it may be useful, with this programming, to start a numeration of the packet different from the automatic one. This programming is not enabled if a total T1 is open. ZEROING ON T2? Programming “ Y” the execution of the total T2 causes the zeroing of the counter of the T1; in this way t he first total T1 after the total T2, is the n°1. Programming “N” , the execution of the total T2 does not cause the zeroing of the counter of the T1; in this way the numbering of the T1 continues in a sequential way up to a maximum of 999999 and then restarts from 1.

ENABLING LEATHERS RECORDING: This variable allows to measure a leather without that it increases the total of the leathers measured (T1), furthermore it disables the print so that it does not modify the total measured. Pressing (disabling of the recording of data) the leathers measured shall neither be memorized nor printed; Setting the recording of the data is enabled (normal mode). LANGUAGE IN USE IN THE PRINTS: In this input type ‘ LIST -BOX’, it is possible to select the language with which you shall print on the heading the totals of the programming parameters. LINE FEED BETWEEN TWO PRINTS: With this print you enable the advancement of the paper of the printer at the end of the print, so that you make easier the tearing. The number set, corresponds to the number of white lines left by the printer at the end of each print. ENABLING MAIN PRINTER: Programming “ Yes” the printer is enabled; programming “No” the printer is disabled. PRINT LIST OF LEATHERS IN THE T1: Programming “ Yes” the print of each total T1 shall contain the list of the measures of each leather; programming “No” the total shall be printed only as a total where it is indicated, besides the heading, the number and total area of the leathers of the packet. PRINT # LEATHERS PER LINE: This input is of the type “ LIST-BOX” and can assume the value of “1” or “3”. In the print of the total T1 it is possible to write a leather for each line setting “1”, or three leathers on the same line setting “3”. It can be useful in the case of measurement of a pallet of leathers where an eventual total T1 could be printed on a long unpractical list. PRINT MODE T1: This input is of the type “ LIST-BOX” and can assume the value of “Progressive” o “End of Packet”. When it is selected PROGRESSIV , the print of the value of surface in the total T1 is made at each end of measure; selecting E ND OF P ACKET , the print of all the total T1 is made at the end of measure of the last leather of the packet.

ENABLING LOGO STAMPING: (Only for the stamper ZIP) Setting “S” it is enabled the heating of the marks in the stamper. The temperature is automatically adjusted on board of the stamper and the advancement of paper it is commanded in alternated way ( short/long) to optimize at maximum the consumption. DISTANCE FROM BOARD LEATHER: You set in centimeters the distance of stamping from the board of the leather. Increasing this value, the stamping is made more internally on t he leather. ENABLING STAMPING OF CHOICES: Programming “S”, on the leather, near the surface, it is stamped the choice set in the frame “W”. According to the type of stamper we have: a number for the numeric representation (0÷6) of the choice; STAMPER ZIP six horizontal segments superposed; the number of stamped TRADITIONAL STAMPER segments represents the choice set. PHOTOCELL 1 (2) COMMAND STAMPER: The signal of reference with which the stamper is commanded, can be determined by external photocells or by photocells of the same measuring front. In the second case, it is possible to program the two photocells, one on the right and the other on the left, in line with the head of print of the stamper. DURATION OF CONVEYOR STOP: (Present only in the prearranged machines) During the phase of stamping, it is possible to stop the belt of transport to obtain a stamping with the leather stopped and keep it well extended. You set the time in seconds of duration of the belt stop. ENABLING COMMAND FOR LEATHER RETENTION: There is the possibility that the code of the leathers is still in phase of measurement while the point of stamping has already passed under the stamper. Activating this function (Yes), the piston of stamping is commanded in any case on the point forecast, retaining the leather until the completion of the measurement. At the end of the writing, the leather is released. Deactivating this function (No), if the point of stamping exceeds the stamper before the end of measurement, the sequence of stamping is interrupted avoiding in this way to stamp externally to the leather.

CHECKS
7.4.1
CHECK C1 It is recalled pressing the keys and <1>. This command allows to perform a f unctional test on the reading bar. The test controls that there are not photocells obscured; on the monitor it appears:
TEST BAR. PHOTOTRANSISTORS OBSCURED: 00000-
# 0-
0-
0-
0-
In the lower line there are the numbers of ten photocells which are concerned by the leather; if the machine is not measuring, the display must be t otally at zero (as in the example). ATTENTION: before performing the test, check that there are not leathers or objects on the reading bar which obscure the photocells. In the machines by conveyor belt (without measuring system on wheels), it is possible to mask, in case of need, some photocells (maximum four) in order to continue to have the operativity of the machine. to activate this command, recall the f rame “SF”; on the monitor it shall appear:
REPLACEMENT REPLACEMENT REPLACEMENT REPLACEMENT

These are normally set up by GER and concern the type of measuring machine and particular functions to be obtained. They can be accessed by removing the LOTO box cover.
8.1.1
CALIBRATIONS ON THE GER132B CARD The calibrations made on this card become operative only after switching off the measuring machine and for some parameters after performing a GENERAL RESET. The card is located inside the LOTO box. DECIMAL SELECTORS A-B-C These allow you to calibrate the surface measurement according to the diameter of the conveyor drive roller. This is an important calibration as it establishes the accuracy of the measuring machine. GER performs and records the calibration in the t est report. A = Selector with greatest effect (approx. 10% per step) B = Selector with average effect (approx. 1% per step) C = Selector with least effect (approx. 0.1% per step) SELECTOR D-1 In the OFF position the stamping command is generated by the LOTO box. In the ON position the stamping command is given by an appropriate photocell before the stamper. SELECTOR D-2 In the OFF position the tail stamping command is preset. In the ON position, the head stamping command is preset. SELECTOR D-3 In the OFF position the LOTO box is preset for ordinary measuring machines with conveyor. In the ON position, the box is preset for measuring machines with hide tendering by means of wheels. SELECTOR D-4 The ON position gives access to the Q6 screen for stamper control. The OFF position disables access to the Q6 screen for stamper control. SELECTOR D-5/6/7 They allow the setting out program operation language like by following table: DIP-SWITCH LANGUAGE 5 6 7 OFF ON OFF ON OFF ON OFF

- SELECTOR D-8 In the machines at conveyor (D3=OFF) it, in ON position, activates the functioning of measure with two wheels encoder for the speed survey. In the machines at conveyor (D3=OFF) it in OFF position activates the functioning of measure with an only encoder for the speed survey. - SELECTOR "E" e "F". Imposed the useful width of the measure front expressed in number of wheels or cards bar. Every card monitors eight photo-transistor. - SELECTOR G-H-L. In the machines at conveyor with increase skin's speed during the measurement, (es.: on press) imposed the second measure area setting in function of the measurement final speed. Like for the selectors A, B and C, it is one important setting because it decides the precision of the measuring machine. The GER effects and records this setting on bulletin of testing. G= Selector at better effect; (approximately 10% per step) H= Selector at middle effect; (approximately 1% per step) L= Selector at lesser effect; (approximately 0.1% per step)

TRIMMER "INTENSITY PROJECTORS"(DIS. E RIF. 27) It stabilizes the voltage of power supply of the bar projectors and allows moreover to adjust the bright intensity. It is accessible removing the rearward cover of the LOTO box. Normally this trimmer has set at approximately half of his excursion to obtain the correct intensity of light given out from the bar projectors; nevertheless in case of necessity (very dusty skins) could be necessary increase the intensity rotating this trimmer in cl ockwise direction. Rotating the trimmer in sense counterclockwise the intensity of light is reduced that could result necessary in the measurement of particular skins with thin thickness..

As with all machines, the measurer may become less efficient with use. For correct measuring, it is very important to maintain machine efficiency. This chapter aims t o instruct the operator so that he can perform all the controls and work necessary to ensure correct operation of the measuring machine.
9.1.1
CLEANING THE PHOTOCELL BAR The beginning of operation of the measuring machine is based on the obscuring of the photocells set under the threads of the carpet to the passage of the skin. That's why motive therefore is good norm proceed to the cleaning of the front of measure once a week with a rag of damp cotton of water. The "P.P." led place in the measure display points out, when it has lit, that at least a photocell results darkened. The flash with this led in absence of skin, generally points out the need to proceed to the cleaning of the bars of reading.
9.1.2
CONVEYOR ROLLER BEARINGS These are fitted in the cast iron supports located at the ends of the conveyor rollers. The bearings are provided with lithium-based grease. In normal working conditions they do not require any maintenance. They must be re-lubricated only if operating in very damp or particularly dirty conditions or if they have to work for long periods at high speed. The bearings can be re–lubricated via a grease hole in the support. For lubrication use a lithium-based grease (SKF LGMT2). The grease must not be injected too energetically in order not to damage the protections.
9.1.3
TRANSMISSION CHAIN It transmits movement from the speed reducer to one of the conveyor rollers. In normal working conditions, it does not require any maintenance but if necessary suitable aluminium greases can be used for lubrication, e.g. VALIANT Seri ATAZ/0 lubricant.
9.1.4
DAILY CHECKS Another important procedure is to perform the daily checks given on the equipment serial number plate. These consist of fiv e control commands which the computer will carry out to check the following peripherals: C1 = Photocell reading bar. C2 = Alphanumeric printer. C3 = Stamper. C4 = Measuring display. C5 = RAM memory.
9.1.5
REDUCTION GEAR OF SPEED The reduction gear has already furnished of lubricating grease. For a possible addition of lubricating, only in the section reduction gear, use a fluid grease to long duration for gears. (greaset IP Atina "0", TOTAL Calindris "O", ESSO Fiber–Grase 370). Check the level of the grease at least once each six months (around 1000 hours of job).
9.2
REPAIRS IMPORTANT: Any repair work must be carried out by specialist or adequately instructed personnel and after informing either the manufacturer or servicing centre. For greater simplicity, work is divided into the following two areas: 1) Reading bar 2) LOTO box
9.2.1
READING BAR Correct operation of the reading bar is indicated by the “ P.P.” led on the measuring display. The led comes on to indicate that at least one photocell is receiving sufficient light from the projector bar. In

practice the “P.P.” led is always off and comes on only when the hide is pre sent over the photocell bar during m easurement.
POSSIBLE FAULTS
REMEDIES
The P.P. led on the measuring display is always on or comes on repeatedly even when there is no hide under the reading bar. When the measuring machine is switched on, a repetitive acoustic signal is generated with a photocell fault message.
Check that above the bar photocells there are not pieces of skin or other material. Check the threads of transport of the conveyor.
One of the hide measurements is periodically skipped (display and printing) and the next hide is recorded with a surface increased by a value similar to the surface of the previous hide.
The P.P. led is always on and the hides are not measured and/or an acoustic alarm signal is generated with the message ***OVERFLOW*** on the alphanumeric display. The P.P. led comes on periodically and inexistent hides with very small surfaces are displayed, printed and stamped.
This happens because at switch-on the obscured photocells are automatically checked. 1) Check that the conveyor is clean as abo ve. 2) Check the power supply voltage; in particular the +12Vdc between terminals 1 and 2 at the rear of the LOTO box. 3) Check the bar connection cable. The problem is on one of the reading bar cards. Repeatedly perform a PARTIAL RESET, switching the measuring machine off and then on again. Every time it is switched on, a bar test is performed. Replace the receiver bar card indicated on the LOTO box monitor. Check the “unit measure” on the ‘ Q1’.
The hide passes under the measuring bar but the P.P. led does not come on and the hide is not measured.
9.2.2
This means that the photocell bar is reading something on the conveyor or that one of the bar cards is not working. Perform a PARTIAL RESET as above. Check the encoder sensor. Perform a GENERAL RESET: switch the measuring machine off and press the BATTERY button for 30 seconds.
LOTO BOX Chapter 4 contains the description of all the parts of the LOTO box which is the main and most complex part of the equipment. To streamline work, the commonest faults are given in the column PROBLEMS and the commonest solutions in the column REMEDIES. The following five areas are distinguished: 1) Printer 2) Power supplies 3) Keyboard 4) Monitor 5) Other work
9.2.2.1
Printer The printer receives the data through the serial connection RS232 with the LOTO box; the power supply has obtained from an appropriate current’s plug at 230V~ set on the side of the machine.
IMPORTANT:
don't connect with other apparatuses to the above-said current’s plug. For any reference to the m aintenance of the printer, see the manual specific enclosure.
