Position of Protective Contactor Combination and Service Socket
Protective contactor combination 3TK2825
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 combination:
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 displaying the
operational mode:
The "Power" LED indicates that voltage is present.
The "Channel 1" and "Channel 2" LEDs light up if the start button has been pressed, the
EMERGENCY STOP loop is closed and the signaling circuit is not signaling a fault status.
