- Input start button
If the operating mode with restart interlock is set, a button must be connected on
the start button input for the start release of the operating movement (Fig. 26/1).
With a free protective field, the yellow LED on the receiver lights up as a start
prompt. Only once the start button has been pressed will the two outputs OSSD1 and
2 of the ULVTE receiver be switched to active.
If the operating mode without restart interlock is set, the start button input (start)
must be unoccupied).
