General Reference Information

THE GATE
Double check the gate and its related hardware. Does the gate move freely? Are there
unprotected pinch points? - If yes, then correct.
WIRING DIAGRAM
Always reference the wiring diagram that was supplied with the operator. Note that some of the
accessory items may have their own wiring diagram.
If you cannot correct the problem or if you feel you will require technical assistance, contact your
local distributor or dealer. If you do not have a distributor or dealer, then contact us for technical
assistance. Please when calling for assistance, make sure you have the gate operator model
number, voltage, phase, horsepower and a list of all accessories that are attached to the operator.
