Spot-weld the sleeve into place on the bottom of the
shoe's U-shaped section. If you are using the shear-pin
assembly, spot weld the sleeve to the bottom of the
shear-pin assembly, and spot weld the top of the shear-
pin assembly to the bottom of the shoe’s U-shaped
section.
Next you must test the temporarily welded position of
the splined shaft's sleeve. Fit the shaft sleeve over the
splined shaft with the U-shaped section aligned in the
gate leaf's fully closed position. Verify with a plumb
line that the axis of rotation falls through the pilot hole
to the center of the splined shaft.
If the axis of rotation alignments are correct, then
permanently weld the sleeve for the splined shaft to the
bottom of the U-shaped section of the shoe.
Also, you now need to weld the pilot hole closed, and
you need to weld the vertical section of the shoe to the
U-shaped section of the shoe.
Lubricate the splined shaft with grease and place the
finished gate leaf shoe over the shaft in the closed
position.
Install the Gate Leaf
If you are not using the telescoping shear-pin assembly,
install the gate leaf by placing its 90-deg corner into the
gate leaf shoe and then installing the top gate hinge.
Installing the top gate hinge may require the gate leaf to
be at a particular height. To raise (or lower) the gate leaf
to the proper height, equally adjust the four leveling
bolts on the base of the drive unit. The bolts raise (or
lower) the splined shaft and thus the gate leaf shoe and
gate leaf.
To test the installation of the gate leaf, first make sure
that the hydraulic system has been disengaged (the
Manual Release lever should point down).
Next, very slowly open and close the gate leaf a few
times to see if it moves smoothly and evenly through its
entire path. As necessary, adjust the leveling bolts on
the base of the drive unit to correct any problems with
the gate’s travel.
Installing the Control Panel
Locate the control panel in the most convenient position
possible, considering the movement of the gate. For
example, a good position for the control panel box in on
the inner face of the post or pillar. Figure 12 shows the
typical layout for a two-leaf gate with the 750 Operator.
If you are embedding the control panel box into a wall
or post, you must be sure to allow a clearance between
the surface of the wall or post and the rim under the lid
of the control panel box.
Installing the control panel consists of six general steps:
•
Connecting the main power to the control
panel
•
Connecting the activating device
•
Connecting the operator to the control
panel
•
Checking the direction of the motor's
rotation
•
Connecting other devices (activating and
reversing) to the control panel
•
Setting DIP switches and potentiometers
for normal operation
The installer is responsible for grounding the gate and
operator systems, for providing the main power breaker
switch, and for making sure that the entire gate system
meets all applicable electrical codes.

Follow the instructions below when installing the
control panel for the 750 Operator.
Connect the Main
Power Supply
WARNING
! Turn the main power off before
you make any electrical connections or set any
switches inside the control panel box.
Wire the main power supply to control panel terminals
in block J1 (see Figures 13 and 14). The installer is
responsible for insuring that a separate, grounded circuit
protected by a circuit breaker is between the control
panel and the main power supply. All wiring should
conform to applicable electrical codes, and all wiring
and fittings should be weatherproof and/or suitable for
burial.
