➤ The MA-zero point entered in the MA-data remains unchanged!

➤ If an adhesive application head is installed on the machine, also the adhesive station zero point must be

checked after any change (adoption) of the MA-zero point correction. No measuring routine is offered for this type

of activity, although the performance is described in section 9.6 "Checking the Adhesive Station Zero Point".

➤ Pay attention to the WORKAROUND pertaining to this menu option → section 12.3.

5.3.5 DETERMINE ECCENTRICITY OF NOZZLE

The description of this menu option is contained in section 5.1.4!

5.3.6 REGISTER PLACEMENT LEVEL Z AXIS

This measuring routine is used to determine the value "REGISTER PLACEMENT LEVEL Z AXIS".

The manual determination that used to be necessary up to and including AutoCal version 110.xxx can thus

be dispensed with.

To determine the value, lower the nozzle onto a PCB of defined thickness (input of thickness in mm), confirm

the contact of the nozzle with the PCB by pressing "Return", the newly determined value is displayed toge-

ther with the old value. This new value can be accepted by means of the function key for YES.

NOTE

Any deviation of the value thus determined from the previous value can have the following causes:

- The effective max. Z-traversing range is not large enough to approach the actual Z-value of the

placement level (see measuring routine "DETERMINE MAX. AND MIN. Z-AXIS TRAVEL RANGES").

This means, however, that the value determined by AutoCal is correct. Troubleshooting activities on the

placement head must be carried out.

- The previous value in the MA-Data was determined manually by lowering onto the conveyor belt, and

the contact point was not selected correctly when so doing.

5.3.7 TRACK MEASURING MENU

The Track Measuring menu is used to determine successively, in the sequence displayed (see submenu,

Fig. 1.10), the exact pick-up positions of the feeder parts of the movable component table and the fixed com-

ponent table. When so doing, the position of the component tables in relation to the gantry is determined.

The following feeder parts with component tables are determined using the Track Measuring menu:

MS-102: Feeder parts 1-4

MS-128: Feeder parts 1-4 and 7 (!)

MS-132: 1 through 5

NOTE for MS-132:

Feeder parts 6 (= waffle-pack changer) and, if required, 7 through 10 ( = waffle-pack trays) are - as before -

determined in accordance with the Service Manual, chap. 2.

5.3.8 DETERMINE SENSOR MOVABLE SIDE ("Width adjustment offset")

This measuring routine is used to measure - for a defined conveyor width - the distance between the refer-

ence point and the Bero switching point in +Y-direction (= "Width adjustment offset").

To carry out the measurement,

prior

to selecting the measuring routine adjust the conveyor width exactly to

the width of the PCB used by means of "CONVEYOR BELT WIDTH ADJUSTMENT" - so that the PCB is con-

veyed without problem to the output station / without jamming. Then enter this PCB width (use a point as deci-

mal place) in mm into the computer when prompted in the measuring sequence to do so.

You require the "Width adjustment offset" value as reference value for automatic width adjustment:

—

In the AutoCal measuring sequence to adjust, for instance, the conveyor automatically to the mapping pla-

te width, to adjust the exact desire width using the "Conveyor width adjustment" function.

—

In the placement cycle, to adjust the conveyor automatically to the PCB width entered in the NU file.

5.3.9 MAPPING MENU

Mapping is used for the automatic measurement of the gantry offset.

On MS-machines the

steel

mapping procedure is offered.

Upon mapping, the PASSPKT (Mapping file) file of the machine is generated. The correction values entered

in this file which were determined by mapping are taken into account in the placement process for ap-

proaching the placement positions. This results in better

placement accuracy

of the station.

The MA zero point correction values previously determined and displayed within the scope of the mapping

procedure must be adopted for the performance of the measurement.

However, the values determined by the "MEASURE MACHINE ZERO POSITION" function will not be over-

written!

Upon selecting "START COMPARISON MEASUREMENT" (not required for the routine check) the compari-

son measurement with respect to the PASSPKT file existing on the hard disk is performed.

To perform the complete mapping process, work through the menu options (see Fig. 1.10) in the sequence

displayed.

➤ The mapping plates for MS-102, MS-128 and MS-132 machines have different dimensions (see chapter

3.3, under the topic "Testing Aids").

➤ The

temperature requirements

for steel mapping must be fulfilled as described in section 5.1.8.

5.3.10 ADHESIVE MENU

When this menu option has been called up, a

submenu

is displayed (see Fig. 1.10).

To calibrate the PCB camera of the adhesive station, the two menu items "DETERMINE CALIBRATION

FACTORS ADH. CAMERA" and "DETERMINE DISTANCE CAMERA - ADHESIVE NOZZLE" are to be cal-

led up successively.

Prerequisite for this calibration are: The MA-zero point and the adhesive station zero point must have already

been checked / corrected (see also "Interdependent Calibrations for Individual Checks, sections 6.1 and 6.4.).

When performing the initial calibration of the PCB camera of the adhesive station, a MA_MSZUS file must al-

ready exist on the hard disk.

5.3.11 AXES INIT MENU

When this menu option has been called up, a

submenu

is displayed (see Fig. 1.9).

The further description of this menu is contained in section 5.1.9!

5.3.12 NOZZLE MENU

When this menu option has been called up, a

submenu

is displayed (see Fig. 1.11).

The further description of this menu is contained in section 5.1.10.

Please note:

—

Prerequisite for the output of this measuring routine is that the nozzle changer for MS-102 or 128 or 132 is

activated in the MA-Data, as indicated in the Service Manual MS-102/132, Chapter 14, section "Nozzle

Changer".

—

The activation of the nozzle changer can be checked during the AutoCal measuring sequence with the aid

of the "EDIT MENU" under "Options", yet it cannot be changed!

DANGER of a PLACEMENT HEAD CRASH

∆

If the hardware of a

nozzle changer

is installed on the machine, it is absolutely necessary that the same

be also

activated by "1"

in the MA-Data.

—

Upon terminating the nozzle endurance run (by pressing any key) the nozzle picked up last is deposited

as assigned, i.e. thereafter

no more

nozzle is picked up. In this connection, observe the

following NOTE!

NOTE

Before starting the placement operation, the

reference status

of the nozzle changer (hardware-software

coordination) must be established as upon the start of the placement cycle the computer assumes that

nozzle

type 104

(normal nozzle) has been picked up (= current nozzle) and that the service position on

the nozzle changer is

free

(Establishing the Reference Status

see section 10.4 "Reworking...").
