After switching on the main switch, you will be prompted to press the START button in order to
start the placement system for placement orders. The same prompt will appear if you opened the
protective covers or pressed the EMERGENCY STOP button.

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
connection (L1, L2, L3, MP and PE). The socket cannot be used with a 4-wire connection, e.g.
without N.
Always follow the safety instructions concerning potentially lethal voltages - even when the place-
ment system is switched off.

The EMERGENCY STOP button is red and shaped like a mushroom. Activated, it remains latched
in its ON position. If you press the EMERGENCY STOP button, the switching contact of the safety
circuit will open and the protective contactor combination (PCC) will trip. 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 buttons closes and the message "EMERGENCY STOP acti-
vated" appears on screen. The following modules:
– PCB conveyor
– PCB clamping
– width adjustment
– PCB stopper and
– used tape cutter
become deactivated.
NOTE
Placement will be interrupted and once the machine is back to functioning mode, may either be
continued or cancelled.

Å With the help of these switches you may check whether the protective covers and other covers
are closed.
– If the covers are closed, the safety contact is closed and the signalling contact is open. If you
open one of the covers, 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).

The protective contactor combination is contained in the power supply unit. It will not be activated
or deactivated if any safety - related functions should fail.

NOTE
For normal mode the key switch remains open, i.e. in position "0".
The key has been drawn.
The protective contactor combination (PCC) trips if one of the protective covers is opened. The
link voltage (200 V) of the gantry axes will be switched off and the link voltage of the star axes
(100 V) will be reduced to 6 VDC. All modules are deactivated.

WARNING
The protective covers must only be opened by appropriately qualified and trained personnel and
only when the key switch is closed (position "I").
The protective contactor combination (PCC) trips as soon as one of the protective covers is
opened. The link voltage of the gantries gets switched off and the link voltage of the star - axes
will be reduced to 6 VDC. The star of the placement head can be cycled at a lower speed if the
cover is open. The following modules:
– PCB clamping,
– PCB stopper,
– lifting table motors and
– tape cutting units
become deactivated.

These sockets are used to supply the necessary voltages as well as the compressed air to the
component 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 to the system. If the component table is not connected, the
protective contactor combination will trip and deactivate all modules.

With the help of these push buttons you may lift or lower the table bed of the component tables.
These push buttons can be activated only after you first moved the placement head out of the
range of the component table and opened the flap over the button. After changing the component
table, you must close the flap over the button again.
– If the flap is closed, the safety circuit contact will close and the signalling contact will open. The
machine is then ready for operation.
– 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
started again with the help of the START buttons.

The following contacts are connected in series and form the safety circuit:
– 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 tables.
– Make contacts for the four flaps over the push buttons for lifting and lowering the component
tables.
