Protective contactor combination 3TK2806 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 circuit must be closed.
– The Start button must have been pressed.
The front side of the protective contactor combination has three green LEDs for the status display
(see fig. 2.8 - 7
, page 92):
– The "Mains" LED indicates that voltage is present.
– The "Channel 1" and "Channel 2" LEDs light up if the Start button was pressed, the EMER-
GENCY STOP circuit is closed and the signaling circuit is not signaling a fault status.
Service socket (item 2 in fig. 2.8 - 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 35)
2.8.4 EMERGENCY STOP Circuits and Signaling Circuit on SIPLACE and SWS
The EMERGENCY STOP functionality of the SIPLACE has been enhanced by the EMERGENCY
OFF circuit of the SWS. For this reason the switching device 3TK2830-1CB30 (K6.1) has been
integrated into the power supply unit of the SIPLACE (see the plan "Extension of SIPLACE CA
EMERGENCY STOP" [00386139]).

2.8.4.1 Structure of the SIPLACE EMERGENCY STOP Circuits
The following contacts are series-connected and form the EMERGENCY STOP circuit:
– normally open (NO) contacts for the four protective cover switches
– normally open (NO) contacts in the two protective switches for the cover flaps over the PCB
conveyor
– normally open (NO) contacts for the two EMERGENCY STOP buttons
– normally open (NO) contacts for the feeder module cover flaps (option)
– normally open (NO) contacts for the four component trolleys or SWSs (wafer feeders)
– channels of the protective contactor combination PCC 6 and the K6.1 (3TK2830-1CB30) ex-
tension
In the EMERGENCY STOP circuit 2, the CAN bus signal for the signaling circuit (see section
2.8.4.2
) is fed to channel 2 of the protective contactor combination PCC K6. If the EMERGENCY
STOP circuit is closed, and the signaling circuit is not signaling a malfunction, then the two green
LEDs for channels 1 and 2 light up, in addition to the green mains power check LED of the pro-
tective contactor combination.
