3. Become familiar with all of Section II,
Installation, before actual installation is
started.
e. Mounting Procedure.
1. Design and Manufacture Foundation.
Foundation m”st be able to withstand at
least 500 ft-lbs torque plus X0 lbs weight.
Refer to Figure 2-2 for footprint dimensions
of power positioner. Use this footprint as a
guide to design foundation to match base of
power positioner. Mounting holes in base are
drilled for l/2 inch foundation bolts. Decide
which foundation material is best suited for
your application, steel or concrete, and
design and manufacture foundation.
2. Installation.
(a)
Install paver positioner on foundation
with l/2 inch bolts and standard flat
washers.
(b) Make sure power positioner is level.
Check by measuring side to side and
front to back with a level.
(c) If power positioner is not level, remove
l/Z inch bolts that secure power
positioner to foundation and install
shims between the power positioner
and foundation. Continue this process
until power positioner is level when
l/2 inch mounting bolts are tightened.
This will prevent distortion of power
positioner stand.
(d) If installed on a concrete foundation,
grout foundation with additional
concrete to prevent distortion of power
positioner stand.
2-4. AIR SUPPLY INSTALLATION. Using Figure 2-3,
match the torque load needed to position your device
to the “maximum torque required” axis along the
bottom of the graph. From this point, move vertically
up to the control torque curve. From the point that
intersects control torque curve, move horizontally to
the left scale labeled “supply air pressure”. This is the
mini”““” supply air required to develop the required
control torque. The stall torque curve represents the
maximum amount of toque the power positioner will
produce for given supply air pressure before stalling
