2.9 Disabling the compressed air supply and discharging
the pressure
The compressed air working pressure of the machine is set to 0.50 ± 0.025 MPa (5.0 ± 0.25 bar).
The position of the compressed air unit is shown at item 1 in fig. 2.9 - 1
, page 82 ) The supply of
compressed air to the machine can be interrupted with the shutoff valve (item 2 in fig. 2.9 - 1
, page
82
).
Use the machine key to release the cover lock.
Lift the cover (see fig. 2.9 - 1, page 82 ).
Turn the lever of the shutoff valve (item 1 of fig. 2.9 - 1, page 82) from the vertical to the hor-
izontal position.
Monitor the operating pressure manometer (item 5 in fig. 2.9 - 1, page 82 ). When the machine
is switched on, the pressure discharges to 0 MPa (0 bar) within 1 minute.

CAUTION
Data loss!
To avoid losing data, assess the following criteria before switching off your machine (apart
from in emergencies):
– Has the machine finished transmitting machine, setup and panel data?
– Has the machine finished processing the PCB?
– Has the machine completed the run-up phase?
CAUTION
Interruption to compressed air supply!
When the machine is switched on, do not use the stop valve to interrupt the com-
pressed 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 machine off at the main switch
and disconnect it from the power supply.
