Component counter (item 4 in Fig. 2.6 - 3) 2
This displays the number of inserted components.
Emergency stop button, latching, with override protection to EN 418
(item 5 in Fig. 2.6 - 3
and item 1 in Fig. 2.6 - 4) 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 pro-
tective 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 button 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. 2
Protective cover switch 1, 2, 3 and 4 (items 1, 2, 3 and 4 in Fig. 2.6 - 4) and protective switch
for covers on the input and output sides of the PCB conveyor (item 5 in Fig. 2.6 - 4
) 2
These switches check whether the protective and any other covers are closed. When the covers
are closed, the emergency stop contact is closed and the signaling contact is open. If one of the
covers is opened, the emergency stop circuit opens and the signaling circuit closes. Some com-
ponents are deactivated or remain active (see Fig. 2.6 - 9
, page 67).

Protective contactor combination 3TK2806 (item 1 in Fig. 2.6 - 6) 2
The protective contactor combination is contained in the power supply unit. It is used to monitor
the emergency stop circuits and safety equipment.
There are three conditions that must be fulfilled in order to activate the protective contactor com-
bination:
– The "software enable" signal must have been sent.
– The emergency stop loop must be closed.
– The Start button must have been pressed.
On the front panel of the protective contactor combination, there are three green operating display
LEDs (see Fig. 2.6 - 8
, page 65):
– The "Mains" LED indicates that voltage is present.
– The "Channel 1" and "Channel 2" LEDs light up if the Start button was pressed, the emergency
stop loop is closed and the signaling circuit is not signaling a fault status.
Service socket (item 2 in Fig. 2.6 - 6) 2
The service socket is contained in the power supply unit and is protected by the cover. It can only
be used if the placement system is connected to the main power supply via a 5-wire connection
(L1, L2, L3, N, and PE). If a 4-wire connection is used, e.g. without N, the socket cannot be used.
WARNING 2
Always follow the safety instructions concerning potentially lethal voltages - even when the
placement system is switched off. (See Section 2.1.5 from page 26) onwards.
