WARNING
!
Strict adherence to the following instructions is mandatory to ensure operating safety:
– Never open one of the two protective covers if you are not completely familiar with the proce-
dure and the operation of the machine. The protective covers are only to be opened when \RX
DUHLQVWUXFWHGWRGRVRLQWKH6,3/$&(RSHUDWLQJPDQXDORULQWKLVPDQXDO
– The key-operated switch is to be unlocked only by qualified, trained personnel.
– The key-operated switch is to be unlocked only when you are instructed to do so in the opera-
ting manual or in this manual!
– When the station is switched on, never place your body (head or arms) in the positioning range
of the gantry!
No changes of any type whatsoever are ever to be carried out unless you are absolutely clear as
to their effect on the overall functioning of the system!
– Only appropriately trained personnel are to perform set-up, changeover or maintenance of the
stations.
– Use only OEM parts and authorized accessories from Siemens. Use of other parts negatively
affects safety and may void liability for the consequences which arise.
– The operating safety of the SMD placement machines is only guaranteed if the SMD place-
ment machines are used as intended and the 6,3/$&(operating manual is observed.
– The machine key and the key for the key-operated switch must be kept in such a manner that
they are only accessible to qualified personnel.
– The SIPLACE test program SITEST (required, for example, during adjustment tasks) is to be
run only by authorized personnel, i.e., persons trained at Siemens to do so.
– If any actions are necessary and no personnel in your company are adequately trained, it is
imperative that you commission a Siemens service engineer to handle it. Remember: No un-
professional action saves money; it may instead end up costing a lot of money.
The operators of the machine are only to perform activities for which they have been adequately
trained and which they have completely mastered.

3 Functional Description
This option uses suction to pick up PCBs 8.5” wide and of various lengths and to hold them pre-
cisely and level on a vacuum plate (tool top plate of vacuum tooling) during the placement pro-
cess. This establishes optimal conditions for placement.
The tool of the “vacuum tooling” is supplied by the Motorola Company.
During commissioning, Siemens makes the compressed air connection and integrates the elec-
trical system into the machine.
The most important functional elements of this option (see Fig. 3 - 1) are
– the tool (consisting of top and bottom plate) on the bottom plate which is placed in a defined
position (see Section 5.1) on the lifting table and held in place there by magnets. Depending
on the model from Motorola, the tool delivered is an 8.5” or an 11” type.
– the vacuum generator to which a number of vacuum branches are connected via multiple dis-
tributors (number varies by tooling model):
The vacuum generator is supplied with 5.5 bar compressed air from the compressed air unit
inside the machine.
The vacuum branches can be connected or disconnected, either manually via shut-off cocks
or automatically by appropriate shut-off valves (varies by model).
– the 3/2-way solenoid valve to shut the vacuum to the option ON and OFF during the place-
ment. process.
– the compressed air interface to connect the option’s vacuum generator to the 5.5 bar compres-
sed air branch inside the machine.
- the "vacuum tooling drive" for conveyor 1 and possibly for conveyor 2 (I/O terminal panel: see
Fig. 3 - 2):
– the electrical interface to connect the option to the power supply / drive:
– When the option is installed, it must also be connected electrically (see Section 5).
– The width adjustment is not deactivated and the optional sequence “vacuum tooling” for fa-
stening the PCB in place are not possible until after this electrical connection is made.

– The PCB moves to the placement area 1 - 4 -> The sonar proximity switch reports “PCB
present” -> The conveyor speed is reduced -> The stopper which has extended in the inte-
rim positions the PCB in the transport direction -> The lifting table starts moving upward ->
