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 work-
ing 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 two separate safety circuits which are monitored
by protective contactor combinations K1 and K2. Both protective contactor combinations are
incorporated into the power supply (see items 14 and 15 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
Protective contactor combinations K1 and K2 monitor the following circuits:
K1: EMERGENCY STOP circuit, safety circuits for the component trolleys or protective cover
switches 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 trans-
former that supplies the gantry axis motors will be interrupted. The voltage to the star-type motor
for the Collect&Place head is reduced from 70 V to 10 V. The DP and DR axes of the placement
heads continue to be supplied with 30 V. The next diagram illustrates the various statuses of K1
and K2 and their effects on the axes and the PCB conveyor components.
