With dip SW2 OFF: input for photocell active during both opening and closure
(NC contact): if obscured during opening, the gate stops moving, but starts
again as soon as the photocell is clear; in closure it reverses the motion
With dip SW2 ON: input sensitive edge (NC contact): both in opening and
closure the gate reverses the motion by 10 cm
