– Use of the option is possible starting with >
No. 1 with dual or single conveyor.
– The position of the sonar proximity switch - and thus the stopper - is limited by the opening in
the tool of the "vacuum tooling" to the middle of the conveyor width.
– The conveyor width must be set to the PCB width to be populated before the option is installed.
The PCB must be moved from loader to unloader without getting stuck and without too much
clearance on the sides.

– This option must be connected directly to an external compressed air supply.
NOTE
When the option is connected to the compressed air system of the placement machine, its proper
operation is no longer ensured.
– The option must be aligned in X- and Y-position on the lifting table:
– At right angles to the direction of transport: The bottom plate must be placed in the middle
of the lifting table parallel to stationary and movable sides. To do this, the transport width
must first be set to the required width for the work with the option.
– In the direction of transport: The vacuum plate (top plate) of the option has to be positioned
such that the PCB lying against the extended stopper is optimally drawn against the suction
cups.
WARNUNG
The vacuum tooling must be position on the lifting table outside the admissible ranges of distur-
bances. Incorrect positioning can result in damage to the machine (or the PCB)!
– The interfaces of the option have to be connected (see Fig. 3 - 1):
- Interface for electricity: connection see "Circuit Diagrams", Section 10.
- Interface for compressed air: The 5.5 bar compressed air branch in the machine has
to be connected to the option’s vacuum generator.

– As customary in the entire working area of the placement heads, the option “vacuum too-
ling”, in particular its vacuum plate (top plate of the tool) and suction cups must be kept free
of components or other foreign bodies.

– Use of the vacuum tooling must be coordinated with Siemens insofar as the spectrum of PCBs
to be populated is concerned.
– The suction cups subjected to vacuum must be completely covered. Vacuum branches of suc-
tion cups which are not covered must be shut off by hand with manual shut-off cocks.
– It is not permissible to use the width adjustment without conveyor bracing.
– The vacuum tooling option automatically cancels the "decrease width" function of the conveyor
width adjustment feature.
– Details on setting the time interval for reducing the vacuum are contained in the chapter "Set-
ting the Time Interval for Vacuum Reduction", Section 3.
The position of the stopper is restricted to a middle position by the opening in the tool of the va-
cuum tooling.
