ELECTRICAL INSPECTION

Under normal conditions, the Daktronics Banner Hoist should

provide years of maintenance free service. Daktronics recommends

periodic electrical inspections for corrosion and wear, particularly

in high temperature and/or high humidity environments. Should

issues occur or if the hoist is exposed to water or other fluids,

immediately disconnect incoming power and contact Daktronics for

technical assistance.
Figure 16 shows the proper wiring for the Banner Hoist power

panel. If electrical issues are observed, this is where technical

assistance will focus.
Figure 17 displays the Banner Hoist RF Receiver and the

schematic of the wiring in the power panel in Figure 16 which

will be used as a reference when receiving technical assistance.

VISUAL INSPECTION

A quick visual inspection can provide valuable information about

how the hoist is operating and whether further maintenance is

required. Periodical visual inspections should be completed in

between scheduled maintenance inspections.
When visually inspecting the hoist, look for components that

have become loose or possible failures such as cracking in the

metal framework or other components. In addition, check for the

following:
· Cables should be tight around the drum, in the correct grooves

and not overlapping

· Cables should follow the correct path from the drum through the

cable guide assembly

· Chains are fitted properly around the sprockets

· Adequate lubrication on the chains and acme screw parts

· Intact wire terminations

· No frayed wires

· No visible corrosion or wear on or around the electrical

components
