2.5.3.1 Description of the functions
EMERGENCY STOP button
When the EMERGENCY STOP button is pressed (item 3 or item 4. in Fig. 2.5 - 4), the motor
voltage to the gantry axes is switched off. The gantry axes are no longer powered, and thus are
not dangerous.
PLEASE NOTE
Placement is interrupted and can then either be continued or canceled once the system is working
correctly again. 2
Protective cover switch
If one of the protective covers is opened (see item 9, 10, 11 or 12 in Fig. 2.5 - 4), the gantry axes
will stop immediately. They are no longer powered, and thus are not dangerous.
Key-operated switch:
If the key switch (item 8 in Fig. 2.5 - 4) is closed (position I), the star can still be paced at low
speed while the protective covers are open. The gantry axes are no longer powered, and thus
are not dangerous.
PLEASE NOTE
The key switch remains open for normal mode, i.e. in the 0 position. 2
WARNING
The protective covers must only be opened, with the key switch closed (position I), by appropri-
ately qualified and trained personnel. 2
2.5.3.2 Status messages and the action required
The following displays may appear in placement mode. If they appear, carry out the action spec-
ified in the third column.

2.5.4 Safety circuits
The SIPLACE automatic placement system has a safety circuit which is monitored by the protec-
tive contactor combination K1. The protective contactor combination is contained in the power
supply unit (see item 14 in Fig. 2.5 - 4
).
WARNING
Automatic placement systems from the SIPLACE family are powered with 3 x 400 VAC (3 x 208
VAC for the U.S.A. version) ± 5 %, 50/60 Hz main power voltage.
This means that some parts of the system carry potentially lethal voltages - even when switched
off at the main power switch. Death, serious injury or considerable damage may result if these au-
tomatic placement systems are handled incorrectly.
Always follow the applicable accident prevention and DIN regulations (particularly EN 60204,
part 1) and the applicable regulations in your own country.
The guard over the power supply must ONLY be opened by appropriately qualified and trained
personnel. 2
The protective safety combination K1 monitors the EMERGENCY-STOP circuits, the safety loops
for the component trolleys or protective cover switches and the enable software signal.
K1 is triggered if any of these functions fail. The main power voltage to the heavy current trans-
former that supplies the gantry axis motors, the star motor, the lifting tables and the used tape
cutter will be interrupted. The DP and Z axes of the placement heads continue to be supplied
with 30 V. The next diagram illustrates the various statuses of K1 and their effects on the axes
and the PCB conveyor components.
