DL7 [status of PHOTO NC] and DL8 [status of EDGE NC] should be constantly ON for the duration of 'POINT E'
You should jumper (short-circuit) [PHOTO NC] & [COM] if DL7 stays OFF and/or [EDGE NC] & [COM] if DL7 stays OFF and see if 'POINT E' proceeds as expected. After finishing programming, you should find the cause of the problem and fix it.
You can use pieces of wire to connect the 2 contacts of each of the 2 contact pairs above, leaving in place any existing wires (so you don't mess anything up) and remove those wires when you are done (restoring everything to its current status).
IF DL7 is always OFF then, as you guessed, the safety photocells are the problem.
- Safety photocells:
- No obstacle: DL7 -> ON
- Obstacle: DL7 -> OFF
- Safety edge:
- No obstacle: DL8 -> ON
- Obstacle: DL8 -> OFF
I'd set DIP14, DIP15 and DIP16 to OFF
