the emergency stop mushroom-head push-button
2.3.2 Residual voltages and discharge times after switching off at the main switch
CAUTION To avoid losing data, evaluate the following criteria before switching off your
automatic placement system (apart from in emergencies):
– Has the placement system finished transmitting machine, set-up and working data?
– Has the placement system finished processing the PCB?
– Has the placement system completed the run-up phase?
– Has the Windows NT operating system been shut down correctly? 2

2.4 Disabling the compr. air supply and discharging
the pressure
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 5 in Fig. 2.4 - 1
. The com-
pressed air supply to the machine can be interrupted using the shut-off valve (item 1 in
Fig. 2.4 - 1
). 2
– You must remove the cover plate to use the shut-off valve.
– Turn the lever on the shut-off valve (item 1 in Fig. 2.4 - 1
) from the vertical to the horizontal
position.
– Watch the working pressure gauge (item 2 in Fig. 2.4 - 1
) and the pressure gauges for the com-
pressed air supply to the component tables and tape cutters or to the stopper (item 3 or 4 in
Fig. 2.4 - 1
). When the automatic placement system is switched on, the pressure discharges
to 0 bar within 1 minute.

DANGER
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 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
