3.1.10. Photocell(s) (optional, but recommended feature)
It is always recommended to connect additional safety mechanisms to
the
D2 Turbo
instead of relying only on the inherent anti-crushing
protection, referred on the previous page.
The typical device is a pair of infrared photocells which can detect the
presence of any vehicle, person or pet that breaks the beam and
communicates back to the
D2 Turbo
that something is in the path of
the gate.
Another option is an inductive loop detector, which is mounted in the
ground, adjacent to the gate, which is very effective at detecting
vehicles or the like, but not persons or pets.

3.1.10.1. Closing
Photocells
Closing photocells provide
additional protection
against your gate closing
on people or vehicles. If
the beam is broken while
the gate is opening, the
gate will continue to open.
If the gate is open, the
gate cannot be closed if the
beam is broken, and if the
gate is closing when the
beam is broken, it will stop
and re-open.
If you select the Autoclose (page
) feature, the gate will remain
10
open if the beam is broken and it will only close after the set
Autoclose time has expired when the beam has cleared.
3.1.10.2. Opening
Photocells
These photocells prevent
your gate from opening if
an object, person or pet is
in the way.
If the photocell is broken
while the gate is closed,
the gate will not open. If
the gate is opening and the
beams are broken, it will
stop then close. If the gate
is closing while the beams
are broken, it will continue
to close.
Gate closed - gate cannot open
Gate opening - gate stops and re-closes
Gate closing - gate continues closing
