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
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. Only one monitored entrapment protection device may be
wired to each input. Additional entrapment protection devices may be wired to the expansion board.
CONTROL BOARD
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 to the full open position, 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.
EXPANSION BOARD
EYE ONLY and COM
Open or Close Direction Photoelectric Sensors, the functionality is based
on the switch settings (located next to the terminals)
Switch set to CLOSE: gate reverses fully when an obstruction is sensed
Switch set to OPEN: gate reverses 4 seconds when an obstruction is
sensed
EYE/EDGE and COM
Open or Close Direction Photoelectric Sensors or Edge Sensor, the
functionality is based on the switch settings (located next to the terminals)
Switch set to CLOSE: gate reverses fully when an obstruction is sensed
Switch set to OPEN: gate reverses 4 seconds when an obstruction is
sensed
