INSTALLATION STEP 9 continued... INSTALL ENTRAPMENT PROTECTION There are three options for wiring the entrapment protection devices depending on the specific device and how the device will function. Refer to the wiring diagram or the specific entrapment protection device manual for more information. These entrapment protection device inputs are for monitored devices, which include pulsed photoelectric sensors, resistive edge sensors, and pulsed edge sensors. NOTE: Only one monitored entrapment protection device may be wired to each input. CLOSE EYES/INTERRUPT (2 Terminals) The CLOSE EYES/INTERRUPT input is for photoelectric sensor entrapment protection for the close direction. When an obstruction is sensed during gate closing the gate will open to the full open position and resets the Timer-to-Close. This input will be disregarded during gate opening. CLOSE EDGE (2 Terminals) The CLOSE EDGE input is for edge sensor entrapment protection for the close direction. When an obstruction is sensed during gate closing the gate will reverse for 4 seconds then stop, disengaging the Timer-to-Close. This input will be disregarded during gate opening. OPEN EYES/EDGE (2 Terminals) The OPEN EYES/EDGE input is for photoelectric sensor or edge sensor entrapment protection for the open direction. When an obstruction is sensed during gate opening the gate will reverse for 4 seconds then stop. This input will be disregarded during gate closing.

INSTALLATION
STEP 9 continued...
INSTALL ENTRAPMENT PROTECTION
There are three options for wiring the entrapment protection devices
depending on the specific device and how the device will function. Refer
to the wiring diagram or the specific entrapment protection device manual
for more information. These entrapment protection device inputs are for
monitored devices, which include pulsed photoelectric sensors, resistive
edge sensors, and pulsed edge sensors.
NOTE:
Only one monitored
entrapment protection device may be wired to each input.
CLOSE EYES/INTERRUPT
(2 Terminals)
The CLOSE EYES/INTERRUPT input is for photoelectric sensor
entrapment protection for the close direction. When an obstruction is
sensed during gate closing the gate will open to the full open position and
resets the Timer-to-Close. This input will be disregarded during gate
opening.
CLOSE EDGE
(2 Terminals)
The CLOSE EDGE input is for edge sensor entrapment protection for the
close direction. When an obstruction is sensed during gate closing the
gate will reverse for 4 seconds then stop, disengaging the Timer-to-Close.
This input will be disregarded during gate opening.
OPEN EYES/EDGE
(2 Terminals)
The OPEN EYES/EDGE input is for photoelectric sensor or edge sensor
entrapment protection for the open direction. When an obstruction is
sensed during gate opening the gate will reverse for 4 seconds then stop.
This input will be disregarded during gate closing.
