If the communication is interrupted the error "COMMUNICATION WITH ICOS IMPOSSIBLE" appears on the
screen:
Select "STORING" → terminate the program for the time being → switch off the machine → eliminate the error.
Possible causes:
— Interruption between computer and ICOS: Check the plug connections to the ICOS at the multiplexer
and the computer, replace the cable, if necessary.
— Incorrect camera no.: Check the camera numbers in the MA-Data (change on the line computer!).
3. The screen display for the conveyor width adjustment incl. the function keys appears:
ADJUST CONVEYOR WIDTH TO PCB WIDTH
➤ The explanation of the function keys is contained in section 5.1.19 "Conveyor Width Adjustment".
4. For checking purposes, place the PCB on the input conveyor, however not over the light barrier, as otherwise
width adjustment cannot be performed. The PCB should not jam nor have too much play.
5. Now, if you have not already done so, adjust the conveyor width to the width of the PCB used, using the
function keys offered (see section 5.1.19).
6. After adjusting the conveyor width, press the "END" function key. The following display appears on the scre-
en:
PLEASE PLACE A PC BOARD OVER THE SENSOR OF THE INPUT CONVEYOR
7. Place the PCB above the light barrier of the input conveyor. The PCB is conveyed to the center conveyor.
8. The graphical display of the position of the calibration plate and the following instructions are displayed on
the screen:
PLACE CALIBRATION PART ON MOTHERBOARD
ADAPTER ON NOZZLE ?
MACHINE MOVING TO SERVICE POSITION
PLEASE PRESS <START> KEY
➤ In place of the adapter also nozzle type 207 from the nozzle changer can be used.
To this end, install the nozzle insert (nozzle top part) in the sleeve of the placement head beforehand!
• Performance of the action:
Open the protective cover → take hold of the calibration plate only (!) by the outer edges → check whe-
ther the calibration plate is oxidized or contaminated: All metal surfaces must have the same coloring
→ replace the calibration plate with a new one, if necessary → place the calibration plate exactly in
the upper right corner of the PCB (see display on the screen) → check the points relative to the directi-
on of travel → slip the adapter onto the nozzle (no pointed nozzle!) → close protective cover → switch
on the control → now press the "START" button → the complete calibration is performed in the follo-
wing sequence:
• DETERMINE CALIBRATION FACTORS OF HEAD CAMERA
• DETERMINE ANGLE CORRECTION OF D-AXIS
• DETERMINE CAMERA NOZZLE OFFSET
• DETERMINE JAW OFFSET

9. The procedure "DETERMINE CALIBRATION FACTORS OF HEAD CAMERA" follows automatically:
• The calibration plate is picked up, centered and put down again, the camera moves over the calibrati-
on plate, the calibration factors are determined, checked and displayed:
CAL. FACTORS CAMERA NO...
X1: -.0088 X2: 1.1783 X3: -.0149
Y2: -.0021 Y2: 1.4934 Y3: -.4704
VALUES X3 AND Y3 ARE NOT STORED BUT OCCUPIED WITH 0.
➤ If the error message "CHECK MEASUREMENT NOT SUCCESSFUL" is displayed, the values deter-
mined are ambiguous.
NOTE
The next menu option can only be performed if the check measurement was correct.
• Troubleshooting:
Press "RETURN" (values are not saved in this case) → press "END" (PCB together with calibration plate
is conveyed to the output conveyor) → remove PCB → visual inspect calibration plate for oxidation or con-
tamination → use new plate, if necessary → repeat the complete measurement (from point 1 onwards).
10. After the measurement has been successfully completed, "DETERMINE ANGLE CORRECTION OF
D-AXIS" follows automatically.
• The plate is picked up, centered, turned, put down and measured. The values determined incl. the de-
viation are displayed:
DETERMINE ANGLE OFFSET
ZERO POINT CORRECTION OLD : .......
ZERO POINT CORRECTION NEW : .......
ANGLE OFFSET MEASURED AND REFERENCE POINT FOUND
• If the discrepancy (old / new) is within the acceptable tolerance, the reference point run is carried out
using the new values. Otherwise, the display appears as under point 11.
11.The measurement is repeated with the new values. If the placement head is not within the tolerance when the
measurement is repeated, an error message is released and a display of the difference determined, as for example:
HEAD OUT OF TOLERANCE
MEASURED VALUE DIFFERENCE AT 0 AND 180 DEGREES: ....... DIGIT
THE VALUE OF THE ZERO POINT CORRECTION WILL NOT BE STORED
PLEASE CORRECT MANUALLY
• Locate the cause of the error (see listing below), eliminate the error and repeat the calibration, starting
with "DETERMINE CALIBRATION FACTORS".
Possible causes:
— Rotation error of D-axis → perform troubleshooting (see Service Manual HS-180, chapter 9,
29mm Head or Service Manual 30mm Head on HS-180)!
— Circular fiducials of the calibration plate are poor / incomplete → use a new calibration plate!
— Calibration factors are incorrect → Redetermine the calibration factors, then repeat the above
measurement!
12. If no error message is issued, the values determined are automatically transferred to the main memory.

13. "DETERMINE CAMERA NOZZLE OFFSET" follows automatically:
NOTE
If, when you are about to individually select this menu option, you are no longer sure whether you have in
the meantime exchanged or turned the calibration plate, you should in any case repeat the calibration,
starting with "DETERMINE CALIBRATION FACTORS".
Measuring procedure:
• The calibration plate is picked up, centered, turned and deposited. The distance between the nozzle
center and camera center is measured.
• The values determined including their algebraic signs are automatically displayed and saved:
CAMERA NOZZLE OFFSET
CAMERA OFFSET OLD X,Y ....... .......
CAMERA OFFSET NEW X,Y ....... .......
CAMERA NOZZLE OFFSET COMPLETED
14. "DETERMINE JAW OFFSET" follows automatically:
• The calibration plate is picked up, centered and put down, several times.
• The values determined are displayed and automatically transferred to the main memory.
JAW OFFSET
Z-JAW CORRECTION OLD : -.05 H-JAW CORRECTION OLD : -.07
Z-JAW CORRECTION NEW: -.05 H-JAW CORRECTION NEW: -.08
JAW OFFSET COMPLETED
15. Check the new jaws correction value displayed.
NOTE
The jaws correction value is displayed in mm (incl. sign).
The max. acceptable Z and/or H-jaws correction value is ± 0.20 mm.
➤ If the Z or H-jaws offset value is larger than ± 0.20 mm: adjust the symmetry of the jaws (see Service
Manual or adjusting instructions for jaws) → repeat the camera calibration, starting with "DETERMINE
CALIBRATION FACTORS".
16. After completion of all four measuring routines, all determined measurement results are displayed.
• Confirm the display with "RETURN".
17. The calibration plate is deposited, the PCB conveyed to the output conveyor and the main menu displayed.
• Remove the PCB, together with the calibration plate, from the output conveyor.
18. From the main menu, select "STORING". The values are transferred to the work diskette.
