• Performance of the action (see screen display):
Open protective cover→ remove MA-zero point gauge → close protective cover → switch on control →
press the "START" button → press "END" → display of the main menu.
➤ After "ECCENTRICITY OF NOZZLE OUT OF TOLERANCE": The values determined are not saved.
➤ After "ECCENTRICITY OF NOZZLE WITHIN TOLERANCE": Perform "DETERMINE HEAD HEIGHT".
7.6 DETERMINE HEAD HEIGHT
Testing aids required:
• Steel nozzle in perfect condition, type 104, item no. 00301435
• Steel plate, completely even and not at all bent, with parallel edges (thickness approx. 2 mm)
(alternatively, a PCB with a side without conduction paths)
➤ For machines up to and including batch identity no. 3 the conveyor width is now to be adjusted to the
width of the PCB (using the handwheel).
1. From the main menu select the menu option "DETERMINE HEAD HEIGHT". The display of the function
keys for width adjustment and the following prompt appear:
ADJUST CONVEYOR WIDTH TO PCB WIDTH
• For the performance of the action and use of the function keys: see section 5.1.19.
• When the adjustment is completed, press "END".
2. After "END" (conveyor width is adjusted) has been pressed, the prompt to enter the PCB thickness is
displayed:
ENTER PCB-THICKNESS [MM]
0.00
3. Measure the plate thickness or the PCB thickness in a place with no conductor paths, using the slide gauge,
and enter the exact thickness in mm into the computer.

4. The following display appears on the screen:
PLEASE PLACE A PC BOARD OVER THE SENSOR OF THE INPUT CONVEYOR
• Performance of the action:
Visual inspection: If a PCB is used, the side with no conductor paths must be facing up ! → insert steel
plate or PCB (the thickness of which was entered) → the plate is moved into the center conveyor.
5. The following display appears on the screen:
CHECK IF Z-AXIS IS ON PCB (NOT IN HOLE OR ELEVATION)
PRESS <RETURN>
• Performance of the action:
Visual inspection: The Z-axis must be positioned on the PCB (condition for the correct measurement)
→ subsequently press "RETURN" in any case.

6. The internally calculated head height is displayed, as for example:
HEAD HEIGHT OLD -- NEW : 30,6------29.9
ACCEPT VALUE(S) ? (YES / NO)
➤ If the Z-axis did not make proper contact with the PCB before the measurement: Press NO → the values are
not accepted → the Z-axis is raised → the PCB moves to the output conveyor → the main menu is displayed.
➤ Z-axis made proper contact: First pay attention to the following NOTE and press, if applicable, YES.
When YES is pressed, the new head height is transferred to the main memory.
NOTE
If there is a significant deviation (old = new) the value should not be accepted and the reason for the
deviation should be determined: check the values in the MA-Data and check sleeve height (see Service
Manuals "30mm Placement Head HS-180", under "Adjustment of the Sleeve Height" or 29 mm Head,
chap. 9, Service Manual HS-180).
7. The following display appears on the screen:
PLEASE REMOVE PCB FROM OUTP. CONV.
PRESS <RETURN>
• Performance of the action: Remove the PCB from the output conveyor → "RETURN" → main menu.
8. Now select the "STORING" main menu and the "TRACK MEASURING MENU" as the next measuring routine.
7.7 TRACK MEASURING MENU
➤ For reasons of tolerances, always used the same adjusting gauge for all stations of a line.
Testing aids required:
• Adjusting gauge (= "iron"), item no. 00120040
• Steel nozzle, type 104, item no. 00301435
• Teach panel, external, item no. 00132207
7.7.1 Procedure: Tracks 2 and 86 of the fixed side
1. From the main menu select "TRACK MEASURING MENU". The submenu (see Fig. 1.4) is displayed.
Select the tracks to be measured in the sequence as displayed on the screen.
2. First select "TRACK 2 OF FIXED SIDE". The following display appears on the screen:
MEASURE TRACKS
PLACE IRON ON FIXED SIDE TRACK NO. 2
PLEASE PRESS <START> KEY
• Performance of the action:
Open protective cover → if necessary clean contact surface on the component table using a dry cloth →
place the adjusting gauge (iron) on the track indicated → close protective cover → "SWITCH ON CON-
TROL UNIT" → "START" button.

3. The placement head moves over the large hole (measuring hole) of the adjusting gauge (taking the values
available in the MA-Data as the basis) → the nozzle is lowered into the large hole.
The following display appears on the screen:
NOZZLE IN MEASUR. HOLE? (5 mm)
4. Check the position of the nozzle. Select the appropriate function key YES / NO.
➤ When NO is pressed the teach panel is activated. The following display appears on the screen:
USE TEACH-PANEL
GUIDE NOZZLE INTO LARGE MEASURING HOLE
• Performance of the teaching procedure:
• "Teach" the nozzle above the large hole (measuring hole) → Select "Z-AXIS DOWN".
• The nozzle must be able to move into the hole. To be able to correct the X and Y-positions by me-
ans of "TEACH", the "Z-AXIS UP" function must be selected on the teach panel beforehand.
• If the nozzle was not able to move into the hole, press the "END" button on the teach panel.
• The further procedure is as described for "YES" in the following.
➤ When YES is pressed (nozzle was able to be inserted into measuring hole) the following display appears:
MEASURE TRACKS
• Measuring sequence: The measuring hole is measured → the placement head is automatically posi-
tioned above the small hole (test hole) → the Z-axis is lowered into the small hole.
5. Thereafter the display appears on the screen:
NOZZLE IN MEASUR. HOLE? (3.5 mm)
• Check nozzle position → press appropriate function key YES / NO.
➤ When NO is pressed (nozzle is not inserted in the test hole) the following is displayed on the screen:
NOZZLE UNABLE TO FIND ORIGINAL HOLE
PRESS <RETURN>"
• Press "RETURN". The measurement is repeated.
• Nozzle is still unable to be inserted into the test hole: eliminate error.
Possible causes:
Sluggishness / error on glass measuring scale/counting error (troubleshooting see Service Manual).
➤ When YES is pressed (nozzle is in test hole) the new and old track positions are displayed.
6. Press the "START" button. The new track positions are transferred to the memory.
The placement head is positioned in the MA-zero point and the TRACK MEASURING MENU is redisplayed.
7. Select "MEASURE TRACKS 2 AND 86 OF MOVABLE SIDE" (procedure as above).
In the case of faulty measurements, select the same track once more.
