2.8.1.2 Machine switched off at the main power switch and disconnected
The machine is unpowered, apart from slight residual voltages in the power supply unit.
2.8.2 Residual voltages and discharge times after pressing the EMERGENCY STOP
button
If the EMERGENCY STOP button is pressed or the machine is switched off, the 300 VDC link volt
-
age for the gantry axes and the 160 VDC link voltage for the star axes are reduced to harmless
residual voltages in a very short time.

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 92 ) The supply of
compressed air to the machine can be interrupted with the shutoff valve (item 2 in fig. 2.9 - 1, page
92 ).
Release and open the cover.
Lift the cover (see fig. 2.9 - 1, page 92).
Turn the lever of the shutoff valve (item 5 of fig. 2.9 - 1, page 92) from the vertical to the hor
-
izontal position.
Monitor the operating pressure manometer (item 2+3 in fig. 2.9 - 1, page 92 ). 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 cleaning
and checking or servicing work, you must switch the machine off at the main switch
and disconnect it from the machine voltage supply.
