3. Select the area for the first mounting hole. Using a No. 7 drill bit, drill the hole
1/2" deep and bottom tap for a 1/4 x 20 thread.
WARNING
When drilling, make sure the holes are at right angles to
the surface. The strain link will not work if the mounting
holes are cocked or angled.
4. Mount the drill fixture supplied with the strain links, align it, and use the long
strain link screw to tighten it to the frame. Use the big hole in the fixture. The
screw will not fit through the other holes.
5. Using the drill fixture as a guide, drill the three remaining holes.
6. Remove the drill fixture and tap the three holes.
7. Mount the strain link (use semi-permanent Loctite—blue, no. 242 or equiv.—on
the mounting screws). Mark each strain link at the cable end to identify its
position on the press. Mark as "left" or "right."
Leave the mounting screws loose for now. Strain links must be properly zeroed
(set close to a 0 volt electrical output under no load) before mounting screws are
tightened.
This zeroing procedure must be done as part of the calibration
procedure in Chapter 3.
Therefore, do not tighten links until you get to that part of the calibration
procedure.
8. Run the strain link cables through flexible conduit to the bottom right knockout
on control box. Use conduit rated NEMA 12.
CAUTION
Do not run strain link wires through the same conduit as power
wires. Strain link wires are sensitive to electrical noise. Separate
conduit will provide protection and shielding.
Plan to leave a service loop inside box. Measure cable for length and cut cable.
Strip outer cable 1" to 2" (2.5 to 5 cm) from end–enough to separate and work
with individual wires. Strip wires 1/4" (6.4 mm) from end.
9. The strain link connectors are at the lower right inside the box. They are marked
"right input" (TB6) and "left input" (TB5). Determine which connector each set of
strain link wires go to.
