1.3.1.3 Description of the functions

Main power switch in the OFF position (items 1 in Fig. 1.3 - 1 1

The main power switch disconnects the three phases L1, L2, and L3 from the power supply.

WARNING 1

The following components still carry potentially lethal voltages even if the main power switch is

switched off:

– Cable connection terminals 1, 3, and 5 of the S1 main power switch

– Mains filter Z1

– Service socket X102

– F1 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 sys-

tems 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 push-button (item 5 in Fig. 1.3 - 1) 1

The emergency stop push-button is red and latches in the ON position when pressed. When you

press the emergency stop push-button the switching contact of the safety circuit opens and the

protective contactor combination (PCC K6) trips. The link voltage (250 VDC) for the gantry axes

and the link voltage (145 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 push-but-

ton closes and the message "emergency stop pressed" appears on the screen. The following

modules

– PCB conveyor

– PCB clamping

– width adjustment

– PCB stopper and the

– used tape cutter

are deactivated.

PLEASE NOTE Placement is interrupted and can then either be continued or canceled once the

machine is working correctly again.

1.3.2 Position of the push-buttons for docking the component trolleys in and out

Fig. 1.3 - 3 Position of push-buttons on the component trolley

1. Push-button on the top

2. Push-button in the guard

E1guard, location 1

E2guard, location 2

E3guard, location 3

E4guard, location 4

Two push-buttons are integrated into the guard module (items E1, E2, E3 and E4). These are used

to dock the component trolley in or out at the location. These push-buttons must be pressed si-

multaneously, if you docking the component trolley.
