IMPORTANT - Never weld parts to the gate or posts when
the operator circuit board is powered. Doing so may damage
the board beyond repair.
Location of Pivot Point
Measurements are taken from the center of the gate
hinge.
The pivot arm needs to be securely mounted to the hinge
post or equivalent mounting surface. It is recommended
to weld the pivot arm to a metal post. In order to achieve
the correct articulation, geometry and rate of speed of the
gate it is critical that the measurements below are followed.
The pivot arm may need to be cut to achieve the correct
placement of the actuator mounting hole. Measurements are
taken from the center of pivot of the gate hinge.
The dimensions shown for both pull to open and push to
open (dim. A and dim. B.) should be adjusted as necessary
depending upon the post size or hinge location. Cut the pivot
bracket and weld the pivot bracket to the base as shown,
being careful to check that the bracket is level.
Calculate the position of the rear pivot bracket using the T5
or T7 graph provided on the next pages. The graphs serve
to establish the dimensions A and B and the value of the
maximum opening degree of the gate.
Important - The values of A and B must be similar to
allow linear movement of the gate and actuator.
Identify dimension C for a pull to open or push to open instal-
lation.
Once C has been identified, draw a horizontal line that
determines the value of dimension B. The point at which the
line you have drawn and the "Recommended installation
line" meet will detemine the value of the maximum degree of
opening.
From this point draw a vertical line down to determine the
value of dimension A. If the degree of opening found does
not corrospond to the requirements of your opening, adjust
dimension A, and if necessary dimension B, so they are
similar.
Do not use values of dimension B below the dotted line on
the graph as they will produce unsatisfactory results.
