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.

(1) Push-button on the top
(2) Push-button in the hand guard
E1 Hand guard, location 1
E2 Hand guard, location 2
E3 Hand guard, location 3
E4 Hand guard, location 4
Two push-buttons are integrated into the hand guard module (items E1, E2, E3 and E4). These
are used to dock the component trolley in or out at the location. To
dock out,
press the push-button
(item 1) on the top of the hand guard. To
dock in,
press both push-buttons at the same time (item
1 and item 2). They are far enough apart from one another that you will need both hands to press
the button. This is intended to prevent the risk of injury to operators while docking the component
trolley in or out.
