Component counter (item 4 in Fig. 2.5 - 4) 2
This displays the number of inserted components.
Service socket (item 5 in Fig. 2.5 - 4) 2
The service socket is contained in the power supply unit and is protected by the safety door. It can
only be used if the placement system is connected to the main power supply via a 5-wire connec-
tion (L1, L2, L3, N, and PE). If a 4-wire connection is used, e.g. without N, the socket cannot be
used.
Always follow the safety instructions concerning potentially lethal voltages - even when the
placement system is switched off. 2
EMERGENCY-STOP-button, latching, with override protection to EN 418 (item 1 in Fig. 2.5 - 5)2
The EMERGENCY-STOP-button is a red mushroom shaped button. It latches in the ON position
when pressed. When you press the EMERGENCY-STOP button the switching contact of the
safety circuit opens and the protective contactor combination (PCC) trips. The link voltage (200 V)
for the gantry axes is switched off, whereas the link voltage (100 V) for the star axis is reduced to
6 VDC. The servo amplifiers for the DP and Z-axes are still supplied with 30 VDC. The signaling
contact of the EMERGENCY-STOP button closes and the message "EMERGENCY-STOP
pressed" appears on the screen. The following modules
– PCB conveyor
– PCB clamping
– width adjustment
– laser light barrier and
– used tape cutter
are deactivated.
PLEASE NOTE
Placement is interrupted and can then either be continued or canceled once the machine is work-
ing correctly again. 2
Protective cover switch (item 2 in Fig. 2.5 - 5) and other cover switches (item 3 in Fig. 2.5 - 5)2
These switches check whether the protective and any other covers are closed. When the covers
are closed, the safety contact is closed and the signaling contact is open. If one of the covers is
opened, the safety circuit opens and the signaling circuit closes. The individual components will
be activated or deactivated, depending on the position of the key-operated switch (item 5).

Protective contactor combination 3TK2805 (item 4 in Fig. 2.5 - 5) 2
The protective contactor combination is contained in the power supply unit. It is not activated or
deactivated if safety-related functions fail.
Key-operated switch in position "0" (item 5 in Fig. 2.5 - 5) 2
PLEASE NOTE
The key switch remains open for normal mode, i. e. in the 0 position. The key is pulled out. 2
The protective contactor combination (PCC) trips when one of the protective or other covers is
opened. The link voltage (200 V) for the gantry axes is switched off, whereas the link voltage
(100 V) for the star axis is reduced to 6 VDC. All modules are deactivated.
Key-operated switch in position "I" 2
WARNING
The protective covers must only be opened, with the key switch closed (position I), by appropri-
ately qualified and trained personnel. 2
The protective contactor combination (PCC) trips when one of the protective or other covers is
opened. The link voltage of the gantries is switched off and the link voltage for the star axis is re-
duced to 6 VDC. The star of placement head can be paced at a lower speed when the cover is
open. The following modules
– PCB clamping
– laser light barrier
– lifting table motors and
– used tape cutters
are deactivated.
Sockets for connecting the CO trolleys (item 1 in Fig. 2.5 - 6) 2
These sockets are used to supply the necessary voltages and compressed air to the CO trolleys.
The terminals for the safety and signalling circuits are also integrated into these sockets. This pre-
vents the placement system being started up before the component trolleys. If the component ta-
ble is not connected, the protective contactor combination trips and deactivates all the modules.

Push-button for raising and lowering the CO trolleys (item 2 in Fig. 2.5 - 6) 2
Use the push-buttons to raise and lower the component trolley table bed. To use this push-button,
and thus the drives for the component table you must first move the placement head out of the
range of the component feeder table and open the flap over the button. After changing the com-
ponent table, you must first close the flap over the button once again.
– If the flap is closed, the safety circuit contact will close and the signalling contact will open. The
machine is then ready for use.
– If the flap is open, the safety circuit is interrupted and the signalling contact closes. An error
message will appear on the screen prompting you to close the flap. The machine can then be
restarted using the Start button.
Uninterruptible power supply (UPS), station computer (item 3 in Fig. 2.5 - 6) 2
Both the UPS and the station computer are contained beneath the input conveyor.
WARNING
Always follow the safety instructions concerning potentially lethal voltages - even when the place-
ment system is switched off. 2
2.5.4 Safety circuit and signaling circuit
2.5.4.1 Structure of the safety circuit
The following contacts are connected in series and form the safety circuit loop :
– make contacts for the four protective cover switches
– make contacts for the two PCB conveyor covers
– make contacts for the two EMERGENCY-STOP buttons
– make contacts for the four component trolleys
– make contacts for the four flaps over the push-buttons for raising and lowering the CO trolleys
– channels 2 and 3 of the protective contactor combination PCC
If the safety loop is closed, 24 VDC is present at channels 2 and 3 of the PCC. The two green
LEDs for channels 2 and 3 light up in addition to the green Power ON LED. 2
