2.7.2.3 Description of the functions
Main switch in OFF position (see item 1 in fig.
2.7 - 3, page 66) 2
The main power switch disconnects the three phases L1, L2, and L3 from the power supply.
WARNING
The following components still carry potentially lethal voltages even if the main power switch is
switched off:
– Cable connection terminals L1, L2, and L3 of the Q1 main power switch.
– Service socket X102 with F1 automatic circuit breaker switched on.
– 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 machines are handled in-
correctly.
Always follow the applicable accident prevention and DIN regulations (particularly EN 60204,
part 1 or IEC 60204, 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.
Main power switch in the ON position 2
After switching on the main switch, mains voltage is present at the inrush current limiter (A2) and
the 24 V- AC/DC converter is addressed. The "power" LED will shine on the protective contactor
combination (K6). The control computer will start up and supply voltage will be made available with
the exception of the intermediate circuit voltages for the gantry axes (260 V-) and star axes (150 V-
).
Stop button, black (items 2 and 7 in fig. 2.7 - 3, page 66 and items 3 + 5 in fig. 2.7 - 4, page 67)2
These buttons are used to stop the machine.
Start button, green (items 3 and 6 in fig. 2.7 - 3, page 66 and items 2 + 4 in fig. 2.7 - 4, page 67)2
After switching on the main power switch you will be prompted to press the start button in order to
start the machine for placement jobs. The same prompt appears if you open the protective covers
or the press the EMERGENCY STOP button.
Component counter 2
The number of placed components (component counter) can be read on the station software. For
more information, refer to the Online Help.

EMERGENCY STOP button with forced locking (item 5 in fig. 2.7 - 3, page 66 and item 1 in fig.
2.7 - 4, page 67) 2
The EMERGENCY STOP button is red and latches in the ON position when pressed. When you
press the EMERGENCY STOP button, the switching contact of the EMERGENCY STOP circuit
opens and the protective contactor combination (K6) trips. The link voltage (260 VDC) for the gan-
try 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 42 VDC. The signaling contact of the EMERGENCY
STOP button opens and the message "EMERGENCY STOP pressed" appears on the screen.
The following modules are deactivated:
– PCB conveyor
– PCB clamping
– Width adjustment
– PCB stopper
– Feeder Control Unit
– Safety valve for the tape cutter
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 1 to 4 (items 1 to 4 in fig. 2.7 - 5, page 68) 2
These switches check whether the protective covers are closed. When they are closed, the
EMERGENCY STOP contact and the signaling contact are closed. If one of the covers is opened,
the EMERGENCY STOP contact and the signaling contact will open. Individual components are
disabled or remain enabled (see fig. 2.7 - 8
, page 75 ).
