2.7.4 Compressed air conditions in the machine after switching off at the main
power switch
When the main switch is switched off or the mains supply to the machine fails, the electrically-con-
trolled main valve of the compressed air unit will close (item 1 in fig. 2.8 - 1
, page 104 ). The pres-
sure will drop to 0 MPa (0 bar) within 5 seconds.
DANGER
Lethal voltages in the power supply unit!
The power supply unit has components (capacitors) which can still conduct potentially le-
thal voltages for approx. 5 minutes, even when the machine is switched off and the mains
plug has been disconnected.
Wait at least 5 minutes before you perform work on the power supply unit.
Only ASM Assembly Systems GmbH&Co.KG service engineers or the machine
owner's service engineers, who have been trained by ASM, may perform work on the
power supply and the safety cutoff (CBS).

2.8 Disabling the compressed air supply and discharging
the pressure
The compressed air unit is located in the sector distributor of location 1 (see fig. 4.2 - 1, page 214
). 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. 2.8 - 1
, page 104. The supply
of compressed air to the machine can be interrupted with the shutoff valve (item 2 in fig. 2.8 - 1
,
page 104
).
Use the machine key to release the cover lock.
Lift the cover (see fig. 2.8 - 1, page 104 ).
Turn the lever of the shutoff valve (item 1 of fig. 2.8 - 1, page 104) from the vertical to the
horizontal position.
Monitor the operating pressure manometer (item 5 in fig. 2.8 - 1, page 104 ). When the ma-
chine is switched on, the pressure discharges to 0 MPa (0 bar) within 1 minute.

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 preven-
tive maintenance or servicing work, you must switch the machine off at the main
switch and disconnect it from the power supply.

WARNING
Risk of injuries!
Risk of injuries from pressurized compressed air lines.
NEVER detach compressed air lines while they are still pressurized.
