The compressed air working pressure is set to 0.52 MPa (5.2 bar). It may fluctuate between
0.5 MPa (5.0 bar) and 0.53 MPa (5.3 bar). The position of the compressed air unit is indicated by
item 5 in Fig. 2.7 - 1
. The compressed air supply to the machine can be interrupted using the
shutoff valve (item 1 in Fig. 2.7 - 1
).
– You must remove the cover plate to use the shutoff valve.
– Turn the lever on the shutoff valve (item 1 in Fig. 2.7 - 1
) from the vertical to the horizontal po-
sition.
– Watch the working pressure gauge (item 2 in Fig. 2.7 - 1
) and the pressure gauge for the com-
pressed air supply to the stopper (item 4 in Fig. 2.7 - 1
). When the automatic placement system
is switched on, the pressure discharges to 0 MPa (0 bar) within 1 minute.

WARNING 2
Automatic placement systems from the SIPLACE family are powered with 3 x 400 V or
3 x 208 VAC (U.S.A. version) ± 5 %, 50/60 Hz mains voltage. This means that parts of the system
carry potentially fatal voltages - even when switched off at the main switch. Death, serious injury
or considerable damage may result if these automatic placement systems are handled incorrectly.
Always follow the applicable accident prevention and DIN regulations (particularly EN 60204,
part 1). The guards over the control and servo units must ONLY be opened by appropriately qual-
ified and trained personnel. 2

2.8.1 Placement system switched off at the main power switch, but still connected
The following table specifies the voltages of assemblies when the automatic placement system is
switched off at the main switch, but still connected to the mains supply.

2.8.2 Placement system switched off at the main power switch and disconnected
The automatic placement system is unpowered, apart from slight residual voltages in the servo
unit.
2.8.3 Compressed air conditions in the machine after switching off at the main
power switch
When the system is switched off at the main power switch (item 1 in Fig. 2.8 - 1) or if the power
supply fails, the electrically-controlled main valve Y1 of the compressed air unit closes (Fig. 2.7 -
1, page 53 ). The pressure will drop to 0 MPa (0 bar) within 5 seconds.
