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 loop must be closed.
– The start button must have been pressed.
The front side of the protective contactor combination has three green LEDs for the operating dis-
play (see fig. 2.8 - 7
, page 93):
– 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 machine 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.

2.8.4 EMERGENCY STOP Loops and Signaling Circuit for SIPLACE and the 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]).
WARNING
Safety instructions about lethal voltages!
Always follow the safety instructions concerning potentially lethal voltages - even when
the machine is switched off. (See section 2.1.3
from page 38)
