IMPORTANT: Determining Correct Setback
E-S 500 / 502 Classic Series Instruction Manual
2.2
PULL TO OPEN - Standard operation. This means the gate operator is mounted on the
inside of the property and pulls your gate in towards the property. If you are going to use
push to open operation “X” out the next 3 pages and use the push to open section
instructions.
To the right are 3 common
examples of setback mountings.
These are not the only options for
mounting.
There a 3 factors to keep in mind when
finding the setback mounting:
1) The measurements must be correct
from the center of the hinge of the gate
to the center of the hole on the mounting
bracket.
2) There must be clearance for your
opener to attach to your gate in the
closed position.
3) The brackets do not move or pivot
after mounting, if you can achieve the
setback and clearance then bracket
position is inconsequential.
It is best to C-Clamp brackets on and test
arm movement clearance before
permanently attaching them.
Variations to the ideal setback can be
made, so long as the total is less than the
combined measurements for the desired
opening arc and the motor body is more
than 2 inches away from the gate in both
the open and closed position. (setback
variations significantly reduces the length
and weight capacity of the operator)
7 ½" 9" 16 ½ 100°
9 ½" 9 ½" 19 90°
To determine the position of the gate
mounting bracket (above is for the post
mounting bracket) refer to step 6 in the
section “Installation of operator”
