Figure 6-9.

Refer to Figure 6-9 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 6-10.
