Daktronics signs are built for long life and require little maintenance. However, from time to time,
certain sign components will need replacing. The
Replacement Parts List in Section 4.11 provides
the names and part number of components that may need to be ordered during the life of the sign.
Most sign components have a white label that lists the part number. The component part number is in
the following format: 0P-_ _ _ _-_ _ _ _ (circuit board) or 0A-_ _ _ _-_ _ _ _ (multi-component
assembly).
Following the
Replacement Parts List is the Daktronics Exchange and Repair and Return
Programs in Section 4.12 . Refer to these instructions if any sign component needs replacement or
repair.
1.2 Safety Precautions
Important Safeguards:
1. Read and understand these instructions before installing.
2. Be sure the sign is properly grounded.
3. Disconnect power when servicing the sign.
4. Do not modify the sign structure or attach any panels or coverings to the sign without
the written consent of Daktronics, Inc.
1.3 System Overview
Daktronics Galaxy AF-3050 signs are designed and manufactured for performance, reliability, easy
maintenance and long life. The pixels have a 20mm center-to-center spacing, and are lit using LEDs
(light emitting diodes). Each sign section has minimum 6-inch character height. A light sensor on the
front of the sign is used for automatic dimming of the LEDs based on the ambient light levels. The
configuration of pixels depends on the model of sign ordered.
The Galaxy model numbers are described as follows:
AF-3050-CCCxBBB-20-R
AF-3050 = Outdoor Galaxy Sign
CCC
= Number of Rows High
BBB = Number of Columns Long
20 = 20mm center-to-center spacing with 6"
Minimum Character Height
R = LED Color (Monochrome Amber or Red)
