➤ If YES has been pressed, continue with point 8.

➤ If NO has been pressed, the following screen display appears:

TEACH CALIBRATION UNIT OVER LASER BEAM

PRESS END-KEY ON THE TEACH PANEL

• Performance of the action:

Position the calibration nozzle in X/Y-directions so that it is approximately centered above the laser

"eye" that is closest to the conveyor (= above the laser beam) → press the "END" button on the teach

panel.

6. The following screen display appears:

DETERMINE COPLANARITY COORDINATES

START: SEARCH LASER FOCUS

7. The height of the laser focus is determined:

The z-axis is slowly moved downward, the highest and lowest point of the laser measuring range

are determined and the center of the measuring range is calculated therefrom.

8. If the measuring range could not be determined, the following screen display appears:

OLD LASER COORDINATES (X, Y, Z) ........... .......... .........

VALUES ARE NOT PLAUSIBLE AND ARE NOT SAVED

PRESS <RETURN>

Possible causes of error:

➤ The glass disk of the laser module is contaminated (for cleaning see Info!)

➤ Clamping of the sleeve (z-axis) is not working properly (for troubleshooting see Service Manual).

➤ Axis controller is not within the permissible tolerances (see measuring routine "CHECK AXIS AD-

JUSTMENT").

➤ The glass disk is damaged or another defect of the laser module has occurred (consult SMD Service

of Siemens AG!).

➤ The serial connection to the coplanarity laser module or serial multiplexer are defective (contact SMD

Service of Siemens AG).

DANGER

∆

For safety reasons the customer is not permitted to perform any troubleshooting activity other than cle-

aning work (with the machine turned off) on the laser module itself!

• Press "RETURN" and after troubleshooting has been terminated start calibration anew.

9. If measurement was successful, the measured results will be displayed, as for example:

— The measuring range of 1.84mm displayed above is a sample values. The values 863 and 912 rep-

resent the highest and lowest measured values of the laser focus, in counts.

NOTE

➤ The following is to be checked: The value of the measuring range must be at least 1.5 mm.

➤ The measurement will always be continued automatically, however, in the case of an error this

measuring routine is subsequently to be repeated, starting from the main menu.

➤ If the value of 1.5 mm is still not reached when the measurement is repeated,

consult the SMD Service of Siemens AG.

10. The X and Y-coordinates are determined. When so doing, the outer edge of the calibration nozzle is

determined and the center of the laser focus in X and Y-directions is calculated therefrom.

• During this measuring process, the figures "> 0" and " -1" are continuously displayed on the screen:

— Figure -1 = laser beam is outside of calibration nozzle area = edge found = O.K.

— Figure ≥ 0 = laser beam is on laser calibration nozzle

• The measurement is performed repeatedly (7x in all), with the newly calculated center being used as

starting point for the next measurement.

• After each measurement the X and Y-coordinates of the laser focus are displayed in mm, referred to

the reference point.

➤ If an error occurs during the measuring procedure, the following screen display appears:

TOLERANCE OF DEVIATION IN X OR Y DIRECTION TOO LARGE

PRESS <RETURN>

• Acknowledge this message with "RETURN". The screen display shown under point 14 appears.

➤ If you do not wish to repeat the calibration, proceed as described under step 19.

➤ If the measurement is to be repeated, simply press the "END" button on the teach panel and restart

calibration from the main menu (see procedure above).

11. If the measurement is satisfactory the following screen display appears, as for example:

LASER CALIBRATION

FOCUSING RANGE IN MM 1.84 863 912

X-,Y-COORDINATES OF LASER FOCUS 373.64 3.31

X-,Y-COORDINATES OF LASER FOCUS 373.65 3.32

etc.

’TEACH’ PLACEMENT HEAD OVER COMPONENT CAMERA

PRESS THE END-KEY ON THE TEACH PANEL

12. Teach the placement head with the laser calibration nozzle installed so that it is centered above component

camera and press the "END" button on the teach panel. Thus the relationship between the laser focus

and the upper edge of the conveyor belt (head height) is established.

13. The following screen display appears:

OLD LASER COORDINATES (X,Y,Z) 373.66 8.64 9.13

NEW LASER COORDINATES (X,Y,Z) 373.64 8.63 9.12

• The new coplan. data are automatically transferred to the main memory.

14. The following display appears on the screen:

LASER CALIBRATION

PLEASE REMOVE THE CALIBRATION UNIT.

MACHINE MOVING TO SERVICE POSITION

PLEASE PRESS <START> KEY

• Performance of the action:

Wait for the placement head to assume the service position → Open the protective cover → remove

the laser calibration nozzle (= measuring part) → install the nozzle required for the following activities

→ tighten the ring nut without pinching the O-ring → close protective cover →switch on the control →

press the "START" button → display of the main menu.

15. Select now "STORING" to transfer the coplan. values from the main memory to the file

MA_ZUSATZ or "_ .sk-" and "_ .kd" of the work diskette.

16. The AutoCal Routine Check procedure of the machine is thus terminated !

Remove the work diskette and carry out any final work required (see section 10.1).

7.16 MEASURE ANY HOLE (REPEATEDLY)

➤ Skip this menu option when carrying out the Routine Check. This measuring routine is only intended for

testing purposes. Observe the description of this menu option (see 5.1.18).

Testing aids required

• Steel nozzle, type 104, item no. 00301435

• Teach panel, external, item no. 00132207

1. From the main menu, select "MEASURE ANY HOLE (REPEATEDLY)". The HOLE MEASURING MENU

is displayed:

HOLE MEASURING MENU

NUMBER OF MEASURING CYCLES 1

WAITING TIME BETWEEN MEASURING CYCLES [MIN] 0.0

NUMBER OF MEASUREMENTS PER HOLE 1

• Move the cursor to the entry field, enter the desired values and confirm with "RETURN". The waiting

time is to be entered in minutes (6 sec. = 0.1 min.).

2. Start the measurement with "CONTINUE" (function key). The following screen display appears:
