ECONDARY
Refer to Figure 6-8 to help plan the most appropriate placement for the photo eyes being installed as secondary
entrapment protection devices. If no other secondary external entrapment protection devices (like edge sensors)
are installed, then at least two photoelectric sensors are required to guard the gate in each direction of travel. If
the photo eyes are tripped, the operator will temporarily stop the gate.
Consult a photoelectric sensor manual for wiring details. Make all electrical connections to Smart DC
Controller as shown in Figure 6-9.

PERATION OTES
• A photo eye trip does not reverse gate.
• The Smart DC Controller software is factory set to stop upon photo eye trip.
• Software is configurable to stop and reverse two seconds upon photo eye trip.
• If the photo eye is cleared within five seconds, the gate will proceed in the direction of travel.
The Smart DC Controller has two photoelectric sensor inputs (EYE OPEN and EYE CLOSE). See
Figure 6-9. Underwriters Laboratories requires that any non-contact sensor used as an external entrapment
protection device, must be tested to, and recognized by, the UL 325 Standard.
