CAUTION
To avoid losing data, evaluate the following criteria before switching off your automatic placement
system (apart from in emergencies):
– Has the placement system finished transmitting machine, setup and panel data?
– Has the placement system finished processing the PCB?
– Has the placement system completed the run-up phase?
– Has the Windows XP operating system been shut down correctly? 2

CAUTION 2
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 preventive maintenance or servicing work, you must switch the placement system off at the

main switch and disconnect it from the power supply. 2
The compressed air working pressure is set to 0.52 MPa (5.2 bar). It may fluctuate between 0.5
MPa (5.0 bar) and 0.53 MPa (5.3 bar). The position of the compressed air unit is indicated by
item 5 in Fig. 2.7 - 1
. The compressed air supply to the machine can be interrupted using the
shutoff valve (item 1 in Fig. 2.7 - 1
).
– You must remove the cover plate to use the shut-off valve.
– Turn the lever on the shut-off valve (item 1 in Fig. 2.7 - 1
) from the vertical to the horizontal
position.
– Watch the working pressure gauge (item 2 in Fig. 2.7 - 1
) and the pressure gauge for the com-
pressed air supply to the stopper (item 4 in Fig. 2.7 - 1
). When the automatic placement system
is switched on, the pressure discharges to 0 MPa (0 bar) within 1 minute.
