- 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. 18/1).
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).
