2.4.3.4 Description of the functions

Main power switch in the OFF position (see item 1 in Fig. 2.4 - 4) 2

The main power switch disconnects the three phases L1, L2, and L3 from the power supply. 2

WARNING 2

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

switched off: 2

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

– main power filter Z1

– BU1 service socket

– 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.

– The uninterruptible power supply and the station computer may also still carry potentially lethal

voltages when the main power switch is switched off.

Æ Death, serious injury or considerable damage may result if these automatic placement sys-

tems are handled incorrectly.

Æ Always follow the applicable accident prevention and DIN regulations (particularly DIN EN 60

204, part 1) and the applicable regulations in your own country.

Æ 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 power switch, the station computer and the machine controller will

start. All supply voltages, apart from the link voltages for the gantry axes (200 V) and the star axes

(100 V) are then available. 2

Stop button, black (item 2 in Fig. 2.4 - 4) 2

These buttons are used to stop the placement system. 2

Start button, white (item 3 in Fig. 2.4 - 4) 2

After switching on the main power switch you will be prompted to press the Start button in order

to start the placement system for placement jobs. The same prompt appears if you open the pro-

tective covers or the press the EMERGENCY-STOP mushroom-head push-button. 2

Component counter (item 4 in Fig. 2.4 - 4) 2

This displays the number of inserted components. 2

Service socket (item 5 in Fig. 2.4 - 4) 2

The service socket is contained in the power supply unit and is protected by the safety door. It can

only be used if the placement system is connected to the main power supply via a 5-wire connec-

tion (L1, L2, L3, N, and PE). If a 4-wire connection is used, e.g. without N, the socket cannot be

used. 2

Always follow the safety instructions concerning potentially lethal voltages - even when the place-

ment system is switched off. 2

EMERGENCY-STOP mushroom-head push-button, latching, with override protection to EN

418 (item 1 in Fig. 2.4 - 5) 2

The EMERGENCY-STOP mushroom-head push-button is a red mushroom shaped button. It

latches in the ON position when pressed. When you press the EMERGENCY-STOP mushroom-

head push-button the switching contact of the safety circuit opens and the protective contactor

combination (PCC) trips. The link voltage (200 V) for the gantry axes is switched off, whereas the

link voltage (100 V) for the star axis is reduced to 6 VDC. The servo amplifiers for the DP and Z-

axes are still supplied with 30 VDC. The signaling contact of the EMERGENCY-STOP mushroom-

head push-button closes and the message "EMERGENCY STOP pressed" appears on the

screen. The following modules 2

– PCB conveyor

– PCB clamping

– width adjustment

– laser light barrier and

– used tape cutter

are deactivated. 2

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

machine is working correctly again. 2

Protective cover switch (item 2 in Fig. 2.4 - 5) and other cover switches

(item 3 in Fig. 2.4 - 5) 2

These switches check whether the protective and other covers are closed. When the covers are

closed, the safety contact is closed and the signalling contact is open. If one of the covers is

opened, the safety circuit opens and the signalling circuit closes. The individual components will

be activated or deactivated, depending on the position of the key-operated switch (item 5). 2

Protective contactor combination 3TK2805 (item 4 in Fig. 2.4 - 5) 2

The protective contactor combination is contained in the power supply unit. It is not activated or

deactivated if safety-related functions fail. 2

Key-operated switch in position "0" (item 5 in Fig. 2.4 - 5) 2

PLEASE NOTE The key switch remains open for normal mode, i.e. in the 0 position. The key is

pulled out. 2

The protective contactor combination (PCC) trips when one of the protective or other covers is

opened. The link voltage (200 V) for the gantry axes is switched off, whereas the link voltage

(100 V) for the star axis is reduced to 6 VDC. All modules are deactivated. 2

Key-operated switch in position "I" 2

WARNING The protective covers must only be opened, with the key switch

closed (position I), by appropriately qualified and trained personnel. 2

The protective contactor combination (PCC) trips when one of the protective or other covers is

opened. The link voltage of the gantries is switched off and the link voltage for the star axis is re-

duced to 6 VDC. The star of placement head can be paced at a lower speed when the cover is

open. The following modules 2

– PCB clamping

– laser light barrier

– lifting table motors and

– used tape cutters

are deactivated. 2
