Main switch in ON position 2
After switching on the main switch, mains voltage is present and the 24 V- AC/DC converter is
addressed. 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 (300 V-) and star axes (160 V-).
Stop button, black (item 2 in fig. 2.7 - 3, page 81 and item 1 in fig. 2.7 - 2, page 80) 2
This button is used to stop the machine. After reaching STOP state protective lock is released and
covers can be opened.
Start button, white (item 3 in fig. 2.7 - 3, page 81 and item 2 in fig. 2.7 - 2, page 80) 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 press the EMERGENCY
STOP button. The protective covers are locked and can no longer be opened.
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.
DANGER
Lethal voltages!
Incorrect handling of the machine can therefore result in death or severe injury or consid-
erable damage to equipment.
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
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 coun-
try.
The safety cover to the power supply must ONLY be opened by appropriately quali-
fied personnel.

EMERGENCY STOP button (item 4 in fig. 2.7 - 3, page 81 and item 3 in fig. 2.7 - 2, page 80) 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 safety contactors trips. The link voltage (300 VDC) for the gantry axes and the link
voltage (160 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
–Star axis
–Gantry axis
