CONCRETE PAD
The concrete pad for operator mounting should be approximately
24" x 24" x 24" in order to provide adequate weight and structure
to insure proper and stable operation. Pad should be 6" above
finished grade (street level) or 6" above top of curb if one is
present. Be sure to position pad so that it is not so close that it
will interfere with the wheel mounting/axle bolts on the gate or
that it is so far away that the rear mounting holes in the base will
be too close to the edge of the concrete form.
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 1/4" thick base plate as
well as washers for leveling. Mounting hole pattern is 15 3/4"
wide by 6 3/4" deep. The rear mounting hole centers (nearest to
gate) will need to be between 6 1/4" and 7" from gate if the chain
brackets that are provided are to be used (based on a gate with a
2" x 2" box tubing frame).
CONDUITS
Use the open area in base of the unit to position your conduits.
(12.0" wide by 10.75" deep). Use 1/2 or 3/4 inch UL listed
conduits. Please observe any requirements in your local electrical
code.
NOTE: Do not attempt to hook up the ac power if wires are LIVE
or HOT. Be sure power is off.

CHAIN INSTALLATION
Before beginning to install the chain, be sure that the centerline of
the mounting holes in the chain brackets are 8 3/8" above the
mounting pad. Once the brackets have been installed and the
mounting holes in the brackets line up with the bottom of idler
pulleys, connect one end of the chain to one end of the gate. Next
thread the chain through the idlers and drive sprocket, then attach
it to the other end of the gate. Cut chain so that the chain
tensioners will not be adjusted out, allowing for as much future
tightening as possible.
NOTE: Please allow 1" of droop (slack) for every 10' of chain.
SAFETY EDGE INSTALLATION
See safety page in front of manual
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 #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.
