2.2.3.4 Functional description
Main switch in the OFF position (see item 1 in Fig. 2.2 - 4) 2
The main switch disconnects the three phases L1, L2 and L3 from the power supply. 2
DANGER 2
The following components still carry potentially lethal voltages even if the main switch is switched
off: 2
– cable connection terminals 1, 3, and 5 of S1 main switch
– Z1 main power filter
– BU1 service socket
– F1 automatic circuit breaker for the service socket
– The color of all individual wires, which still carry potentially lethal voltages even if the main
switch is switched off is brown.
– The uninterruptible power supply and the station computer may also still carry potentially lethal
voltages when the main switch is switched off.
Å Incorrect handling of the placement system can therefore result in death or severe injury or
considerable damage to equipment.
Å Always follow the applicable accident prevention and DIN regulations (particularly DIN EN
60 204, part 1) or the regulations specific to your country.
Å The safety doors to the power supply unit must only be opened by appropriately qualified and
trained personnel.
Main switch in the ON position 2
After switching on at the main switch, start the station computer and machine controller. All supply
voltages, apart from the link voltages for the gantry axes (200 V) and star axes (100 V), are then
available. 2
Stop button, black (item 2 in Fig. 2.2 - 4) 2
These buttons are used to stop the placement system. 2

Start button, white (item 3 in Fig. 2.2 - 4) 2
After switching on at the main switch, you will be prompted to press the Start button in order to
start the placement system for placement jobs. The same prompt appears if you open the protec-
tive covers or press the emergency stop mushroom-head push- button. 2
Component counter (Item 4 in Fig. 2.2 - 4) 2
This displays the number of inserted components. 2
Service socket (Item 5 in Fig. 2.2 - 4) 2
The service socket is contained in the power supply unit and is protected by the safety doors. It
can only be used if the placement system is connected to the main power supply via a 5-wire con-
nection (L1, L2, L3, MP and PE). If a 4-wire connection is used, e.g. without N, the socket cannot
be used. 2
Always follow the safety instructions concerning potentially lethal voltages - even when the place-
ment system is switched off. 2
Emergency stop mushroom-head push-button, latching, with override protection to EN 418
(Item 1 in Fig. 2.2 - 5) 2
The emergency stop mushroom-head push-button is a red, mushroom-shaped button. It latches
in the ON position when pressed. When you press the emergency stop mushroom-head push-but-
ton, 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 axes is reduced to 6 VDC. The servo amplifiers for the dp and z axes are still
supplied with 30 VDC. The signalling contact of the emergency stop mushroom-head push-but-
tons closes and the message "Emergency stop pressed" appears on screen. The following mod-
ules: 2
– PCB conveyor
– PCB clamping
– width adjustment
– PCB stopper and
– used tape cutter
are deactivated. 2
PLEASE NOTE Placement is interrupted and can either be continued or cancelled once the
machine is restored to working order. 2

Protective cover switches (Item2 in Fig. 2.2 - 5) and other cover switches (Item3 in Fig. 2.2 - 5)2
These switches check whether the protective and other covers are closed. When the covers are
closed, the safety contact is closed and the signalling contact is open. If one of the covers is
opened, the safety circuit opens and the signalling circuit closes. The individual components will
either be activated or deactivated, depending on the position of the key switch (Item 5). 2
Protective contactor combination 3TK2805 (Item 4 in Fig. 2.2 - 5) 2
The protective contactor combination is contained in the power supply unit. It is not activated or
deactivated if safety-related functions fail. 2
Key switch in position "0" (Item 5 in Fig. 2.2 - 5) 2
PLEASE NOTE The key switch remains open, i.e. in position "0" for normal mode. 2
The protective contactor combination (PCC) trips when one of the protective or other covers is
opened. The link voltage (200 V) to the gantry axes is switched off and the link voltage for the star
axes (100 V) is reduced to 6 VDC. All modules are deactivated. 2
Key switch in position "I" 2
WARNING 2
The protective covers must only be opened by appropriately qualified and trained personnel
when the key switch is closed (position "I").
The protective contactor combination (PCC) trips when one of the protective or other covers is
opened. The link voltage to the gantries is switched off and the link voltage for the star axes is
reduced to 6 VDC. The star of the placement head can be paced at a lower speed when the cover
is open. The following modules: 2
– PCB stopper
– lifting table motors and PCB clamping
– used tape cutters
are deactivated. 2
Sockets for the component change-over tables (Item 1 in Fig. 2.2 - 6) 2
These sockets are used to supply the necessary voltages and compressed air to the component
changeover tables. The terminals for the safety and signalling circuits are also integrated into
these sockets. This prevents the placement system being started up before the component tables
are docked. If the component table is not connected, the protective contactor combination trips
and deactivates all the modules. 2
