Safety field interruption:
The safety outputs of the TNT 35/7-24V are opened (LED "OFF/ON" on red) if during
safety operation the light beam of the protective photo electric sensor is interrupted.
The restart-disable inside the TNT 35/7-24V becomes active and prevents an automatic
restart of the machine. The yellow LED "Start" displays the function of the restart-disable.
The TNT 35/7-24V is in waiting state and can be restarted by pressing the start-/restart
button after the safety field is free.
