1.2.3.1 Functional description
● Emergency stop button
When the emergency stop button is pressed (item 3 or item 4. in Fig. 1.2.4
), 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 cancelled once the system is working correctly
once more.
● Protective cover switch
If one of the protective covers is opened (see item 9, 10, 11 or 12 in Fig. 1.2.4
), the gantry axes will stop
immediately. They are no longer powered, and thus are not dangerous.
● Key switch
If the key switch (item 8 in Fig. 1.2.4
) 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.
WARNING
The protective covers must only be opened, with the key switch closed (position
I
), by appropriately qualified
and trained personnel.
1.2.3.2 Status messages and the action required
The following displays may appear in placement mode. If they appear, carry out the action specified in the
third column.

automatic placement systems have two separate safety circuits which are moni-
tored by protective contactor combinations K1 and K2. Both protective contactor combinations are incorpo-
rated into the power supply (see item 14 and 15 in Fig. 1.2.4
).
DANGER
Automatic placement systems from the SIPLACE family are powered with 3x400VAC ± 10%, 50/60Hz 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 VDE regulations (particularly VDE 0113) and the appli-
cable regulations in your own country.
The guard over the power supply must ONLY be opened by appropriately qualified and trained personnel.
Protective contactor combinations K1 and K2 monitor the following circuits:
K1:Emergency stop circuit, safety circuits for the component tables or wafflepack changer,
protective cover switch and the enable software signal
K2:Emergency stop circuit, K1 protective contactor combination, software enable signal and key switch
K1 or K2 is triggered if any of these functions fail. The mains voltage to the heavy current transformer that
supplies the gantry axis motors will be interrupted. The voltage to the star-type motor for the revolver head is
reduced from 70V to 10V. The dp and dR axes of the placement heads continue to be supplied with 30V. The
next diagram illustrates the various statuses of K1 and K2 and their effects on the axes and the PCB conveyor
components.
