The main switch disconnects the three phases L1, L2 and L3 from the power supply.
DANGER
The following components still carry potentially lethal voltages even if the main switch is switched
off:
– 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 uninterruptable power supply and the station computer may also still carry potentially
lethal voltages when the main switch is switched off.
– Incorrect handling of the placement system can therefore result in death or severe injury or
considerable damage to equipment.
NOTE
The color of all individual wires, which still carry potentially lethal voltages even if the main switch
is switched off, is brown.
Å Always follow the applicable accident prevention and DIN regulations (especially DIN EN 60
204, part 1) and the specific regulations of your country.
Å The safety doors to the power supply unit must be opened by appropriately qualified and
trained personnel only.

Switching on of the main switch, will 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.

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.
