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?

Edition 08/2011 EN 2.10 Disabling the Compressed Air Supply and Discharging the Pressure
101
2.10 Disabling the Compressed Air Supply and Dis-
charging the Pressure
The operating pressure of the machine and SWS is fixed to ± 0.025 MPa (5.0 ± 0.25 bar). The
position of the compressed air unit is shown by item 1 of the fig. 2.10 - 1
. You can interrupt the
flow of compressed air to the machine with the shutoff valve (item 2 of the fig. 2.10 - 1
).
The SWS is supplied with compressed air via the machine.
Use the machine key to release the cover lock.
Lift the cover (see fig. 2.10 - 1).
Turn the handle of the shutoff valve (item 1 of the fig. 2.10 - 1) from vertical to horizontal po-
sition.
Observe the operating pressure manometer (item 5 of the fig. 2.10 - 1). When the automatic
placement system 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.
