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 (not provided).
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 (NOT PROVIDED)
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 obstruction is sensed
Switch set to OPEN: gate reverses 4 seconds when 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 obstruction is sensed
Switch set to OPEN: gate reverses 4 seconds when obstruction is sensed
