WIRE THE ENTRAPMENT PROTECTION DEVICES + EARTH GROUND ROD
WIRING
To prevent SERIOUS INJURY or DEATH from a moving gate:
• Entrapment protection devices MUST be installed to protect anyone who may
come near a moving gate.
• Locate entrapment protection devices to protect in BOTH the open and close
gate cycles.
• Locate entrapment protection devices to protect between moving gate and
RIGID objects, such as posts or walls.
WIRE THE ENTRAPMENT PROTECTION DEVICES
Entrapment protection devices are required. Refer to page 5 for more information regarding application.
EARTH GROUND ROD
Use the proper earth ground rod for your local area. The ground wire must be a
single, whole piece of wire. Never splice two wires for the ground wire. If you should
cut the ground wire too short, break it, or destroy its integrity, replace it with a single
wire length.
1
Install the earth ground rod within 3 feet of the control box.
2
Run wire from the earth ground rod to the control box. The earth ground wire
will be connected in a later step.
NOTE: If the operator is not grounded properly the range of the remote controls will
be reduced.
Check national and local
codes for proper depth
To Control Box
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 product manual for more information.
1
Connect the entrapment protection device to the EYES EDGE terminal on the
control board. These inputs are for pulsed photoelectric sensors and dry contact
edges.
• Close Photoelectric Sensor Entrapment Protection: Connect wires from the
photoelectric sensors to the Inputs on the CLOSE EYES/INTERRUPT terminal.
• Close Edge Entrapment Protection: Connect wires from the entrapment
protection device to the Inputs on the CLOSE EDGE terminal.
• Open Entrapment Protection: Connect wires from the entrapment protection
device to the Inputs on the OPEN EYES/EDGE terminal.
NOTE: Refer to the “Wiring Accessories to the Control Board” section on page 33.
