The compressed air working pressure is set to 5,1 bar, although it may fluctuate between 5.0 and 5.3 bar.
The position of the compressed air unit is indicated by item 4 in Fig. 1.4.1
. The compressed air supply to the
automatic placement system can be interrupted using the shut-off valve (item 1 in Fig. 1.4.1
).
- You must remove the cover plate to use the shut-off valve.
- Turn the lever on the shut-off valve (item 1 in Fig. 1.4.1) from the vertical to the horizontal position.
- Watch the working pressure gauge and the pressure gauge for the compressed air supply to the stopper
(item 2 and 3 in Fig. 1.4.1
)
When the automatic placement system is switched on, the pressure discharges to 0 bar within 1 minute.

WARNING
NEVER disconnect compressed air lines while they are pressurized. Risk of injury!

DANGER
Automatic placement systems from the SIPLACE family are powered with 3 x 400 V ± 10 %, 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 placement systems are handled incorrectly.
Always follow the applicable accident prevention and VDE regulations (particularly VDE 0113).
The guards over the control and servo units must ONLY be opened by appropriately qualified and trained per-
sonnel.
