CONCRETE PAD
The concrete pad for operator mounting should be approximately
24" deep x 24" wide x 26" long in order to provide adequate
weight and structure to insure proper and stable operation. Pad
should be 6" above finished grade (street level) even with top of
6" curb if one is present. Be sure to position pad so that the
operator mounting bolts are not too close to the edges of the
concrete pad. See drawing on page 3A.
NOTE: Pad must always extend below the frost line in areas
where the ground freezes.
ANCHORS
Proper anchors for fastening operator to pad will be a 1/2" x 6"
wedge anchor patterned to match the mounting base of the unit.
They should be installed with approximately 1" showing above
concrete surface in order to allow for the 3/8" thick base as well
as washers for any leveling. See drawing on page 3A.
CONDUITS
The Mega Swing UL is equipped with 1/2 and 3/4 knockout in the
back of the accessory cabinet. It is recommend that the conduits
come up under the outer enclosure. If wiring must be brought in
from outside the enclosure, be sure to follow all required
electrical codes. The conduits may come up any where beneath
the enclosure except under the mounting angles which the unit is
mounted with.
NOTE: Do not attempt to hook up the 120/230 Vac mains if wires
are LIVE or HOT. Be SURE power is off.
SAFETY EDGE INSTALLATION
It is highly recommended that a pressure sensing edge (safety
edge) be installed at the leading edge and at all hazard and pinch
points of the gate. Choose an edge that will cover the full height
of the gate. It should be installed securely and any coil cord used
to send the signal back to the operator should be cut so that
excess cord be eliminated to prevent it from getting tangled in the
gate or mechanism. Edges that are to REVERSE and re-open a
closing gate connect to J5 #5 and commons #9 - #12. Edges that
are to STOP the gate that is opening or closing will connect to the
2 pins on the JP2 block near the center of the board.
DRIVE ARM ADJUSTMENTS
To adjust the length of the Primary Arm, you can use any two of
the holes that line up with the two holes in the pivot plate that
mounts to the top of the output shaft. You will need to cut off any
excess material that extends off the back side. Install the two
bolts and tighten them securely.
To adjust the Secondary Arm, there are two set screws under the
ARM ENDS that can be loosened to allow that section to be
adjusted. It may be necessary to cut the aluminum tube to a
shorter length for some installations.

NOTE: Distance from top of concrete pad to bottom of plate that
mounts on gate is 26.9".
A= Primary Arm: Output shaft pivot point to elbow pivot point.
B= Secondary Arm: Elbow pivot point to gate plate pivot point.
C= Gate hinge pivot point to gate plate pivot point.
D= Gate leaf to output shaft pivot point (as measured while open).
E= Gate hinge pivot point to output shaft pivot point.
F= Where to begin back of pad. It is 9" less than the "E" dimension.
G= Required clearance for (B) secondary arm at full open position.
