1 USEFUL RECOMMANDATIONS

1.1 Important

First read this manual carefully in order to avoid causing damage or injury to your setting bench unit as a result of incorrect use. GV METROLOGIA disclaims all liability for any malfunction caused by the use of the unit in a way that does not comply with the instructions contained in this manual. 1.2 Warnings signs

Motorised mobile part. Do not touch the setting bench or the mobile slide while moving them.

Risk of electrical shock

Safety measurement due to electromagnetic fields is required.

General warning

1.3 Safety precautions Strong impulsions emanating from electromagnetic fields may damage the electronics. Therefore, direct contact with all exposed steel components must be avoided. Under no circumstances the unit shall be opened so as to prevent damages or alterations from occurring while operating.

Should any malfunction arise as the unit or one of the accessories is being used, switch it off and contact your local GV METROLOGY customer service.

The electronics is fitted with high-tension components that make them dangerous to touch. Therefore, only qualified personnel, aware of the risk involved, is entitled to do any work requiring access to the electronics.

The holding force controlled over the motorised system is high. A special attention should be paid during any displacement.

2 INSTRUCTIONS FOR A CORRECT USE

Your bench unit includes a system that is able to restore the absolute position of the reference slide that could have been lost. If so, you’ll be asked to reset the unit to zero as described in chapter 5.2.

Should you use tools fitted with moving parts (e.g. removable arm) that can be tighten using a screw capable of producing a strong measuring or clamping force, it is advisable to use the fine setting device. During the setting procedure, the reference slide must not be moved forcibly along the measuring axis as this may

result in incorrect position of this feature, thus bringing about a warning sound. In

this case, you’ll have to repeat the whole procedure as described in chapter 5.2. Not using the support-screws will cause the loss of the warranty

If the ambient conditions vary from those applied at the time the bench unit was set and calibrated (i.e. reference temperature at 20° ±0,5° C), all relevant setting values must be compensated for according to the coefficient of linear expansion matching that of steel. Temperature variations occurring during shipment may result in faulty operating as the procedure for automatic positioning is in progress (looking for the zero). In such case, the slide may position itself on any value before the desired one could be reached. If so, you’ll get a message telling you that a TRACKING error or I*I*t has occurred. To avoid this happening, we advise to leave the unit unused for at least 48 hours until temperature has stabilised, thus matching that of your workshop or your laboratory.

Both messages TRACKING error and I*I*t may appear during manual or automatic

positioning. If the problem results from a collision, press several times to have

the current operation be ended and to return to main menu. To move the reference

slide to a higher value, press . Once the reason for collision has been

eliminated, press to start the procedure to search for the zero as described

under point 5.2.

“ZERO IN PROCESS, ERR. POSITION X! ” occurs when the zeroing of the machine is

not done properly. In this case, slide manually with the movable reference

around 140 mm and then press for zeroing: instruction video on youtube – GV

There are extra adapters available as an option.

Preparing the unit

1 Prepare a table or a surface area that’s suitable to support the weight of the unit, made of steel,

iron or granite. Or any material which do not deform because of the weight. 2 Prepare the screws/pins/shock-absorber 3 Lift up the machine, and screw 2 pins on a side and 1 central pin on the opposite side. They will

support the weight. For model from 1000mm and above, screws 2 more pins on the side where you initially have screwed 1 central pin. These additional 2 pins will work to keep the machine balanced, they don’t have to support much weight.

4 Balance the unit horizontally in a place avoiding doors, gates, air conditioning, fans, direct sunlight. 5 If the environment is very dirty/oily, a polycarbonate protection is suggested.

5 Connect DC jack outlet (11) to

the 18 V DC input (10) at the rear of the unit.

6. Activate the movement of the mobile part by pressing F1 X 2 TIMES. 7. In order to select a new value with tolerances proceed as described in point (4-6). To exit this

automatic mode press two times ESC (22) ( ) 5.7 Moving by manual steps The manual mode allows you to set the various positions where the mobile slide will stop at regular intervals. With regard to this, see both points about – Internal/External measurement In automatic mode, this setting is allowed providing the measuring mode for internal dimensions was previously selected.

5.7.1 Manual value setting for stepped displacement

First press the key twice in order to access main display window. Enter desired step length (e.g.

0.015), and then press ENTER to confirm. From then on, activating either of both keys as

often as necessary will cause the slide to move to the right or the left from the chosen length.

5.7.2 Automatic value setting for stepped displacement

Press both keys + simultaneously from main menu. Once this is done, enter all needed data in the following order: - Number of cycles (e.g. 10). - First value (e.g. 20). - Last value (e.g. 100). - Step length (e.g. 5).

Press ENTER to confirm each value input. Once all data have been input in the given order, you may scroll through displayed values using both

arrow keys .

Use the key to enable stepped displacement of the slide, which starts moving automatically before staying into position for about 3 seconds at each step (e.g. 20, 25, 30, 35 up to 100 in the first cycle, than 100, 95 down to 20 in the second cycle, and so on until the 10th cycle is performed).

15

Make sure that the difference between both first and last values is a multiple of the chosen increment (step length). If not, the length of the last steps will be arbitrary. No excess of the limit values is allowed.

Pressing these keys + at the same time once again will cause the same procedure to be repeated. The automatic step-by-step programme sequence as saved will remain unchanged as long as no

changes are made. For value displaying, press any key + or prior to . 5.8 Choosing a language

6 USING THE ACCESSORIES

Any accessory or adapter can only be mounted once the mobile slide has been positioned to desired value, and it needs to be removed before positioning the slide back again, so as to eliminate any risk of collision resulting in faulty operation. 6.1 Identifying adapters for the 2-points standard bore gauge. N.B. For bore gauge with reversed dial indicator, the adapter A300044 is needed. To choose the right adapter you have to :

a). Identify the shape of the bore gauge foot ( or base ) which can be:

RECTANGULAR ROUND.

↓ ↓

↓ ↓

b). measure the foot width. measure the foot width.

18

c). Identify the proper adapter. N.B. For bore gauge with foot width less than 20 mm or bore gauge with round foot: only dedicated size adapters available.

In case of rectangular foot ( starting from 20 mm width ), the Versatile adapter is available. It is possible to choose adapter i.e. AL55090 which will work with foot width from 55 to 90 mm or i.e. AL28035 works with foot width from 280 to 350 mm. The arch-shape of these adapters ensure the self centering of the bore gauge on the ceramic. Counter adapter AL300003 ( in the picture on the left ) is needed for any AL adapter.

7.4 Adapter for external range reduction to 10 mm ( 0.4 in ) A300031

Fig.1 - Adapter A300031

Enable the Offset

1. Push F2 twice to zeroing the machine as per usual procedure. 2. Mount the adapter A300031 on the 2 metallic reference carefully on the 2 ceramic pads ( do

not tight the screws yet ). 3. To align the 2 accessories with 2 metallic reference bars so that they are perfectly on the

same axis. 4. Now tight the screws very lightly. 5. To enable the new zero set of the machine given by the 2 accessories, enter the main menu

from the keyboard by pressing PGdown, then press F3 offset. The machine requires a reference nr, enter number 6 and press ENTER.

TAR-AL is now ready to be used with the reduction adapters for the reduction of the minimum external value. To return to the standard functions of the machine it is enough to press ESC several times ( 2/3 times ).

7.5 Procedure for first setting the new zero offset and periodical checking of the offset.

To use the adapter A300031 on the TAR-AL , it’s necessary to insert a new setting in the machine memory as a second ZERO OFFSET value ( to recall every time these adapters are used ). It’s necessary to check the offset at least 3 times per year or at every weather season swift. The value must be inserted in the list of the OFFSETS in the TAR-AL memory and at first use must be checked and reset if needed ( we remind that the machine and its adapters are produced and set at controller temperature 20° ± 0.2 and all sets can be affected by any temperature change ). Inserting the adapter Offset :

1. Switch ON the bench and proceed with the zeroing ( F2 x 2 ).

2. From the main menu press PgDw (2) ( ) , entering the following submenu:

31

3. Select F2) param ( ) , to access at the 2nd sub-menu and digit the password (123456)

+ confirm with ENTER ( ) . In the new menu select F4) TAB/OFF ( ) , then press F3)

OFFSET ( )

4. In the opening menu, according to the order, insert:

a. Code-name referred to the accessory ( i.e.1 or 2 or 6 ) (important: do not overwrite the existing codes in the TAR-AL

b. . If the display shows the value of the article i.e. ”1”, press the down arrow until the display shows on the first empty line - ████████ █ )

Code-name: 6 – confirm with ENTER ( )

c. Value of the coefficient “M” = 1.000000 always to be written with n°6 decimals

after the decimal point ) – confirm with ENTER ( )

d. Value of the Offset “Q” = 13.00 – confirm with ENTER ( )

5. ESC from the parameters-insert mode by pressing ESC ( ) , and save the setting of the

value just entered by pressing at the same time “SHIFT” + “Y ” ( + ) . Then press

ESC ( ) to go back to the main menu.

Checking of the adapter offset : This procedure allows the re-setting of the adapter’s OFFSET value and to correct possible errors. It has to be done with a certified OD micrometer (it’s also possible to use a micrometer which

has just been zeroed on the ceramic reference of the TAR-AL ). NB. This procedure must to be redone also the first time the offset is entered in the new environment / shopfloor. Procedure. 1. Turn on the machine and press F2 x 2 to zeroing the machine. Mount the 2 accessories fixing

on the same axes. 2. To enable the measurement range with the accessories, from the main menu, press

PGdown, then F3 offset. The machine requires the article or name-code and digit number 6 + Enter.

3. Set a value over 20.000 mm (see pag. 10 of User’s manual ) and check the noticed value with a certified micrometer i.e.. 19.993 mm. The eventual difference from the set value (20.000 mm) and the noticed one (19.993 mm) represent the error of the offset to be adjusted. In this case: 20.000 – 19.993 = 0.007 mm

N.B. In case of negative offset, insert the value adding the minus sign : ( - ) ( )

4. Repeat again the procedure described from point nr.2 until point nr. 4 but this second time insert the parameter Q at the same value of the Offset previously noticed. In this example case:

F1)ESTERNAL F2) Param

F3)OFFSET F4) AUTOM

F2)LANGUAGE

F3)mm/pol F4)TAB/OFF

32

Q = 13+0.007 =13.007

5. ESC from the insert mode of parameters by pressing ESC ( ) , save the settings of the

value just entered by pressing at the same time “SHIFT” + “Y ” ( + ) , then press ESC

( ) to go back to the main menu.
