2.7.5 Compressed air conditions after switching off at the main switch
When the main switch is switched off or the mains supply to the placement machine fails, the elec-
trically-controlled main valve of the compressed air unit will close (item 1 in fig. 2.8 - 1
, page 96 ).
The pressure in the placement machine 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 placement machine has been switched
off and the mains plug has been disconnected.
When working on the power supply, switch off the main switch, secure it to prevent
switching on again, disconnect the placement machine from the power network and
wait 5 minutes until the capacitors have discharged.
Test to check that there is no remaining voltage supply. See the procedure described
in the service manual.
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 at location 2 (see fig. 4.2 - 1, page 192 ).
The working pressure of the placement 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 96. The supply of com-
pressed air to the placement machine can be interrupted with the shutoff valve (item 2 in fig. 2.8
- 1, page 96 ).
Use the machine key to release the cover lock.
Lift the cover (see fig. 4.2 - 1, page 192 ).
Turn the lever of the shutoff valve (item 1 of fig. 2.8 - 1, page 96) from the vertical to the hor-
izontal position.
Monitor the operating pressure manometer (item 5 in fig. 2.8 - 1, page 96 ). When the place-
ment machine is switched on, the pressure discharges to 0 MPa (0 bar) within 1 minute.

CAUTION
Interruption to compressed air supply!
When the placement 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 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.
