
If the safety-related input is not activated (actuator of Emergency Stop pushbutton pushed
down), the device remains in the operating state Run: Outputs Deenergized. The motor remains
at a standstill.
If the safety-related input is activated (actuator of Emergency Stop pushbutton pulled out), the
device transitions to the operating state Run: Outputs Energized (T3). The motor runs. This
operating corresponds to regular operation of the machine.
If an application function with synchronization
( see page 41 ) of the safety-related input is used,
this transition only occurs if the input channels of the safety-related input are activated within the
synchronization time.

In the operating state Run: Outputs Energized, the device monitors the state of the safety-
related input.
If the actuator of the Emergency Stop pushbutton is pushed down (the safety-related input
deactivated), the safety-related output is deactivated within the response time (transition T4 to
operating state Run: Outputs Deenergized). The device is again in the defined safe state. The
motor is stopped.
This corresponds to the Emergency Stop condition of the machine.

To return to the operating state Run: Outputs Energized (T3), the start input and the safety-
related inputs need to be activated again (start button pressed and actuator of the Emergency
Stop pushbutton pulled out).
If an application function with synchronization
( see page 41 ) of the safety-related input is used,
this transition only occurs if the input channels of the safety-related input are activated within the
synchronization time.
