Mounting a Sectional Display
Follow these steps to mount a sectional display.
Note: The bottom section has protective faceplates on the top. These faceplates are a
protective measure for safe traveling. By removing the faceplates, any and all
openings on the top of the bottom section are exposed and the display is vulnerable.
Because of this, the top section needs to be attached to the bottom section very soon
after the faceplates are removed. Before combining the sections, examine the inside
of the bottom display to ensure no foreign objects entered the display that may
damage internal components. Daktronics is
not responsible for any damage that is a
result of postponed top section installation.
Behind the second module in the bottom row of the top section is a padded envelope
that contains the needed hardware.
1. Carefully uncrate the display and inspect each side of the display for possible
damage that may have occurred during shipping.
2. Mount the bottom section first.
3. Remove the eyebolts from the top of the bottom display that secure the
faceplates.
4. Carefully remove the faceplates making sure not to damage the protective
sealant around the top of the display. Any damage done to the sealant may result
in rusting or worse damage to the display. Daktronics is not responsible for any
damage resulting in damaged sealant, and if the sealant is harmed during
faceplate removal, the
warranty will be void .
5. Install alignment pins to help set the top section onto the bottom section. The
alignment pins are stored in the padded envelope mentioned above.
6. Following the guidelines described in Section 2.4, lift the bottom display into
position on the support structure.
7. Weld or use 1/2" Grade-5 bolts and hardware to secure the clip angles to the
support structure as shown in
Drawing B-227417.
8. Remove the first, second and every even module from the bottom row on the top
section. There should be two holes visible in both the top and bottom sections
where the modules are removed.
9. Set the top section on to the mounted bottom section.
10. Remove the alignment pins.
11. Use the bolts found in the padded envelope to secure the top section.
12. Install the bolt and washer into the captivated nut in the bottom section.
13. Torque the bolts to 40-50 ft/lbs torque.
14. Re-install the modules and the power and signal jacks.
15. Refer to Section 3 for information on routing power to the display and the
communication manual for routing the signal.
16. After installation is complete, carefully inspect the display for any holes that
may allow water to seep into the display and seal any openings with silicone –
if
the eyebolts on the top of the display have been removed, plug the holes
with bolts that were removed with the eyebolt (unless there is an overhead
structure).
