CAUTION 2
To avoid losing data, assess 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?
2.8 Disabling the compressed air supply and discharg-
ing the pressure
The compressed air working pressure of the placement system is set to 0.50 ± 0.025 MPa (5.0 ±
0.25 bar). The position of the compressed air unit is indicated by item 1 in Fig. 2.8 - 1
. The com-
pressed air supply to the machine can be interrupted using the shutoff valve (item 2 in Fig. 2.8 - 1
).
Æ Use the machine key to release the cover lock.
Æ Lift off the cover (see Fig. 2.8 - 1).
Æ Turn the lever on the shutoff valve (item 1 in Fig. 2.8 - 1) from the vertical to the horizontal po-
sition.
Æ Watch the working pressure gauge (item 5 in Fig. 2.8 - 1). When the automatic placement sys-
tem is switched on, the pressure discharges to 0 MPa (0 bar) within 1 minute.
CAUTION
When the machine is switched on, do not use the stop valve to interrupt the compressed air sup-
ply 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.

WARNING
NEVER detach compressed air lines while they are still pressurized. Risk of injury. 2
