When the emergency stop button is pressed or the placement system is switched off, the electrolytic capaci-
tors quickly discharge to safe residual voltage levels via switched resistors on the discharge board
(00308443-xx).
The voltages can be tapped off at test sockets 001 - 009 on the voltmeter unit in the servo unit.
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 guard over the servo unit must ONLY be opened by appropriately qualified and trained personnel.

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?

Edition 04/98 1.4 Disabling the compressed 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 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!
