WIRING

WIRE THE ENTRAPMENT PROTECTION DEVICES

Entrapment protection devices are required. Refer to page 5 for more information regarding application.
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.
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 "Accessory Features on the Control Board" section on
page 27.
TO ERASE LEARNED MONITORED PHOTOELECTRIC
SENSORS
1
Remove the photoelectric sensor wires from the terminal block.
2
Press and release the SET OPEN and SET CLOSE buttons simultaneously until the
SET OPEN and SET CLOSE LEDs turn on.
3
Press and release both SET OPEN and SET CLOSE buttons again to turn off the
SET OPEN and SET CLOSE LEDs.
NOTE: For dual gate applications repeat the steps above on the other operator.

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 operator.
2
Run wire from the earth ground rod to the operator.
NOTE: If the operator is not grounded properly the range of the remote controls will
be reduced.
