CAUTION
To avoid the risk of loosing any data, evaluate the following criteria before you switch off your
automatic placement system (emergencies excluded):
Has the placement system finished transferring machine, set-up and working data?
–Has the placement system finished operation on the PCB?
–Has the placement system completed the run - up phase?
–Has the Windows NT operating system been shut down correctly?

The compressed air working pressure is set to 5.3 bar + 0.2 bar. The position of the compressed
air unit is indicated by item 4 in fig 2.4 - 1
. The compressed air supply to the machine can be
interrupted using the shut - off valve (item 1 in fig 2.4 - 1
).
Å Open the protective door.
Å You must remove the cover plate to use the shut - off valve.
Å Turn the lever on the shut - off valve (item 1 in fig 2.4 - 1) from the vertical to the horizontal
position.
Å Watch the working pressure gauge and the pressure gauge for the compressed air supply of
the stopper (item 2 or 3 in fig 2.4 - 1
).
– If the automatic placement system is switched on, the pressure discharges to 0 bar within 1
minute.
CAUTION
When the machine is switched on, do not use the stop valve to interrupt the compressed air supply
for more than 30 minutes. If you need to shut off the pneumatic system for longer in order to carry
out maintenance or servicing work, you must switch the placement system off at the main switch
and disconnect it from the power supply.
