➤ When NO is pressed (nozzle is not in measuring hole) the following display appears on the screen:

MEASUREMENT NOT IN ORDER

DO YOU WANT TO REPEAT MEASURING?

— When NO: The measuring operation is continued as described below from YES onwards (nozzle is

in measuring hole).

— When YES: The measurement is repeated (see above, point 4).

If the nozzle was not able to enter the checking hole properly when the measurement was repea-

ted, determine the cause.

Possible causes:

- Axis adjustment out of tolerance / nozzle concentricity out of tolerance (perform measuring routine!),

- Sluggishness / error on glass measuring scale / counting error (for corrective action see Service

Manual).

➤ When YES (nozzle is in measuring hole): The placement head is positioned above the movable compo-

nent table

10. The following display appears on the screen:

REMOVE THE MACHINE ZERO POINT

PLEASE PRESS <START> KEY

• Performance of the action:

Open the protective cover → lift out gauge in upward direction → close protective cover → switch on

the control → Remove MA-zero point gauge → Press "START" button → display of the main menu.

NOTE

After acceptance of the X / Y-zero point correction values, the "min. and max. X / Y-travel paths" must al-

ways be determined manually and be entered in the MA-Data by means of the EDIT MENU.

7.4 Determining the Min. and Max. X / Y-Travel Paths

Following any change of the MA-zero point correction values, the X and Y-travel paths must be determined

and entered in the MA-Data.

➤ No measuring routing is available for this purpose. Proceed as described in the following.

WARNING

∆

DANGER OF A PLACEMENT HEAD CRASH!

➤ To prevent the placement head from colliding with the tape reels of the electric feeder modules, the

conveyor width must

first be set up to maximum width.

➤ Move the X and Y-gantry axes to the limit switches only after the above has been completed.

1. "CONVEYOR BELT WIDTH ADJUSTMENT" → Adjust the conveyor to max. width (on machines up to

batch identity no. 3 using the handwheel).

2. Select "END" → the main menu is displayed → open the protective covers (corresponds to EMERGENCY STOP).

3. Open control cabinet → disable X and Y-axes on the axis controller cards.

4. Now approach the limit switches of the X and Y-axes in the sequence specified below and make a note of

the values determined.

NOTE

Press against a suitable place on the gantry carriage or take hold of the head by the grip.

Sequence of steps for manual determination of values:

• Move the X-axis into the direction of the output station until the limit switch releases an audible click.

- If no "clicking" can be heard: limit switch is defective or maladjusted (see Service Manual).

- Clicking can be heard: Read off the value (counts) from the axis controller card.

• Deduct 20 counts from this value and take this value down as "max. X-axis travel range".

• Push the X-axis toward the front in the direction of the input station until this limit switch audibly

clicks.

• Again read off the value from the X-axis controller card → again deduct 20 counts from this value →

take this value [in counts] down as "min. X-axis travel range".

• Now determine and make a note of the min. and max. travel paths of the Y-axis proceeding in the

same way as described for the X-axis (Caution: Y-axis above the movable component table toward

the left = max. Y-travel path) → deduct 20 counts in each case → take down these values properly as-

signing them to the min. / max. Y-travel paths.

5. As a final step, make absolutely sure that none of the limit switches is actuated !

➤ Therefore slide the X and Y-axes sufficiently far toward the machine center.

NOTE

If one of the limit switches is actuated upon continuing the AutoCal program sequence, this would lead to

malfunctions!

6. Now re-activate the X and Y-axes on the axis controller cards.

7. Close the control cabinet door and the protective covers.

8. From the main menu now select the "EDIT MENU" and thereafter "X-AXIS" / "Y-AXIS".

9. Observing the correct assignments, enter the four values [in counts] in the MA-Data under "MIN. / MAX. X /

Y-AXES TRAVEL RANGES".

NOTE

If more than 20 counts are deducted the component camera is likely to lie outside the travel range. Pay

attention to the negative sign of the minimum travel paths (see Fig. 12.2).

10. From the EDIT MENU select "STORING" → the values determined are saved to the work diskette.

11. Accept the travel path values via the "AXES INITIALIZING MENU" → "ALL AXES".

7.5 Determining Concentric Running of Nozzle

Tools and Testing Aids Required

• Steel nozzle, type 104, item no. 00301435

• New MA-zero point gauge with 2 holes, item no. 00120060

• Spherical hexagon socket screw key size 3

From the main menu select "DETERMINE ECCENTRICITY OF NOZZLE" whereafter the following display

appears on the screen:

DETERMINE ECCENTRICITY OF NOZZLE

PLEASE PRESS <START> KEY

The

further procedure

(insert MA-zero point gauge and install steel nozzle) is as described for "Measure

Machine Zero Point" (from point 2 up to and including point 3).

After the "START" button is pressed, the nozzle moves into the measuring hole of the

gauge and starts measuring the concentricity of the sleeve: After each measurement the nozzle is raised,

turned by 90 degrees and lowered again into the measuring hole.

The values

determined for the concentric running of the nozzle together with the evaluation of the re-

sults

are displayed, as for example:

DEGREES Y X in COUNTS

0 20190 5300

90 20189 5301

etc.

ECCENTRICITY OF NOZZLE IS (X,Y) 1 1 [DIGIT]

ECCENTRICITY OF NOZZLE WITHIN TOLERANCE

REMOVE THE MACHINE ZERO POINT

PLEASE PRESS <START> KEY

➤

If the deviation is too great

(sleeve runout > 0.02 mm in total) the following

error message

is dis-

played

ECCENTRICITY OF NOZZLE OUT OF TOLERANCE

ECCENTRICITY DETERMINATION OF NOZZLE IS IMPOSSIBLE

➤ Previously determined values are invalid. The error on the placement head must be eliminated as fol-

lows:

—

29 mm head: Troubleshooting, see Service Manual, chapter 9 "Placement Head".

—

30 mm head: Troubleshooting can

only be carried out at the factory

by customers especially trained

by SIEMENS AG according to the instructions contained in the "Special Service Instructions 30 mm

Placement Head".

NOTE

The placement head has to be removed for troubleshooting. After the installation of a (replacement)

placement head the

complete

procedure must be repeated beginning with the start of the program!
