INFORMATION ON THE MANUAL

3.1

AIM OF THE MANUAL

R

.

L

.

This manual contains all instructions for the use and maintenance of the “LOTO L” measuring machine. It is designed mainly for the machine operators as most of the information concerns the controls and programs that must be run to obtain maximum performance from the equipment; it therefore aims to instruct the end user re. correct use of the machine. However, as it is mainly a measuring system, the manual also contains information on thickness and surface measurement settings for the sole use of maintenance personnel.

3.2

LIMITS OF THE MANUAL The equipment consists basically of electronic components designed and produced by the manufacturer. Owing to their complexity and the fact that information concerning their construction is confidential, they will not be discussed in detail in this manual but treated as machine assembly “parts” (electronic cards) with their specific reference code. For more detailed information, please contact the servicing center by fax or the manufacturer itself, specifying the characteristics of the equipment, the reason for the request and position held by the applicant within the firm. The servicing center and/or the manufacturer reserve the right to supply specific documentation at their discretion.

3.3

STORAGE OF THE MANUAL This manual is considered an integral part of the machine and must be kept in a clean dry place. After consultation, it must be put away carefully in an easily accessible place near the machine. Generally the manual is consulted during the first month of operation of the machine; subsequently only the summary sheet of commands given in enclosure “N” is used. You should not leave the manual on the machine as it could be easily damaged or used incorrectly by other non-authorized personnel. WARNING: in case of sale or transfer of the machine to other user, make sure that the manual accompanies the machine always, to permit at the new owner to inquire on the operation and on the relative warnings. The same affair also is valid in case of transfer of the activity without removal of the machine.

3.4

USER RESPONSIBILITY Application of the equipment is extremely simple and does not require any particular user precautions but the following points must be observed: 1° During installation  Correct ROTATION DIRECTION of the conveyor as described in table “A”.  The LEVEL WITH POSITION of the measuring machine. 2° The general power supply must be the same value marked on identification plate with accepted voltage variations within 10%. 4x1.5 mm² NPI cable must be used (fire retarding) in compliance with C.E.I. 20-22 standards. The power installed is 1 kW. If the power supply cable is placed at less than 100 cm from power supply cables of other equipment with systems controlled by electronic drives, shielded-conductor cable must be used. Provide a cut-off device for the measuring machine power supply with 4A fuse protection. The cut-off device must be sized for a minimum power of 1 kW.

L

.

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 that they have necessity of measure the surface of the skins having a complete series of precise data like final result it is 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 to 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 messages.  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. Even 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 must be inside the lower limit of 64.6 dm² and the superior one of 65.4 dm² (64,6 HOURS 0 MIN 0 START -> DATE: 0/ 0 HOUR 0: 0 #Leathers 0 Sup.= 0.00 HOUR AVERAGE: # Leathers = 0 Sup.= 0.00 It displays data related to the production. In the frame QK there is a programming which allows to determine when the machine has the production in progress and when it is in pause. If it is programmed in progress, this display is automatically updated according to the to the leathers measured; in detail we have: DURATION: It displays in hours and minutes the total time of actual production; START: It displays the date and hour related to the start of the count.
