2.4.1.3 Description of the functions
Main power switch in the OFF position
The main power switch disconnects the three phases L1, L2, and L3 from the power supply.
Cable connection terminals L1, L2, and L3 of the Q1 main power switch
Z1 line filter
Service socket BU1
FBU automatic circuit breaker for the service socket
The color of all individual wires, which still carry potentially lethal voltages even if the main power
switch is switched off, is brown.
– Death, serious injury or considerable damage may result if these automatic placement systems
are handled incorrectly.
– Always follow the applicable accident prevention and DIN regulations (particularly DIN EN 60
204, part 1) and the applicable regulations in your own country.
– The safety door to the power supply must ONLY be opened by appropriately qualified and trained
personnel.
EMERGENCY STOP pushbutton, latching, with override protection to EN 418
The emergency stop button is red and latches in the ON position when pressed. When pressed, the
emergency stop button opens the switching contact of the emergency stop circuit - the protective
contactor combination (PCC K1) triggers. The link voltage (200 VDC) for the gantry axes and the link
voltage (150 VDC) for the star axes is switched off. The servo amplifiers for the DP and Z axes are still
supplied with 40 VDC. The signaling contact of the EMERGENCY STOP button will open and the
message
EMERGENCY STOP operated
will be shown on the screen. The following assemblies will
be disabled:
PCB conveyor
PCB clamping
Width adjustment
PCB stopper
Empty tape cutter.

DANGER:
The following components still carry potentially lethal voltages even if the main
power switch is switched off:
NOTE:
Placement will be interrupted and can then be continued or canceled once the
machine is functional again.

2.4.3 Safety and Signaling Circuit
2.4.3.1 Safety Circuit Function
The following conditions must be fulfilled in order to start and operate the placement machine:
All four component trolleys must be docked in and connected.
All protective covers must be closed.
The two cover flaps over the PCB conveyor must be closed.
Both emergency stop buttons must be released.
The cover flaps (option) over the feeder modules must be closed.
The minimum operating pressure must have been reached.
The "software enable" signal must be active. This ensures that the safety circuit is closed.
The power supply must be sending 24 V to the Start buttons and the protective contactor
combination.
If one of the start buttons is pressed now, the protective contactor combination PCC K1 will switch
and enable the following components:
– 200 VDC link voltage for the servo amplifiers for the gantry axes
– 150 VDC link voltage for the star axes
– The axis unit receives a "Servo enable" signal for the servo amplifiers
– 40 VDC operating voltage is switched to the component trolleys.
– 24 VDC operating voltage is switched to the used tape cutters.
– The PCB conveyor control receives the enable signal for the PCB clamping, the PCB stopper
and the lifting table control.
The machine is then ready for use.
