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 8 1/4" wide
by 9 1/8" deep. The rear mounting hole centers (nearest to gate)
will need to be between 5 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
The area available in base of unit to position conduits is 10 3/4"
wide by 7 1/4" deep. All conduits must be cut down to 1 1/2" in
height to allow for the insertion of the equipment accessory shelf.
The equipment accessory shelf maybe installed after all conduits
are cut to proper height and all wiring has been properly routed.
NOTE:
Do not attempt to hook up the 120VAC mains 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 1/2" above the
mounting pad. Once the brackets have been installed and that 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.
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 #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.
