9. Mount the vessel to the LD3xi/LD3xiC.
a. Lower the vessel gently onto the Load Discs.
(Alignment pins may be used to help guide and
position the vessel.) (See Figure 3-4)
b. Center the Load Disc top mounting holes with the
vessel mounting holes, using the clearance
available from the bottom mounting holes.
Note: If the vessel hole pattern does NOT match up with
the Load Disc hole pattern, modify the mounting holes on
the vessel. DO NOT hammer or force the Load Disc into
position by tightening the mounting bolts. The vessel holes
will need to be resized or relocated.
c. Place the four top bolts (customer supplied)
through the vessel and the Load Disc mounting
holes. The bolts must be able to pass freely
through the holes without interference.
d. Tighten the bolts, leaving a 1/4-inch gap for
positioning. (See Figure 3-2)
11. Check dead weight output.
a. Record the dead weight output on your Weight
Distribution Chart that was started on page 3-3.
b. Calculate the Output Change. (Change should be
positive.)
Note: All output changes should
be positive! If you observe a
negative output change, check
wiring polarity and vessel load
shifting.
