Introduction
2
The FuelightTM Series includes standard petroleum price displays. In the United States the
displays employ a 9 to represent the 9/10 fraction.
The displays are designed for installation in an existing or custom sign or can be mounted
to a sign structure. FuelightTM cabinets, specially developed for outdoor use, are
constructed of heavy-gauge aluminum. Digit faceplates are black and are set directly
into the surface of the display.
Amber, green, or red LEDs are used in FuelightTM displays to illuminate numeric digits. LEDs
are high-intensity, low-energy lighting units.
FuelightTM displays are controlled using one of the following communication kits: FLR3-100
(includes an RC-50 key fob remote), FLR3-1500 (includes a DM-100 controller and xed-
mount radio), or FLD3-2000 (DM-100 controller).
Safety Precautions
• Please read and understand installation instructions before installing.
• Do not disassemble control equipment or electronic components of the display;
failure to follow this safeguard will void the warranty.
• Disconnect display power before servicing power supplies to avoid electrical shock.

2 Mechanical Installation
Important Notes:
• Read and understand these instructions before installing the display.
• Do not drop the transmitter/controller or allow it to become wet.
• Disconnect power when servicing or not using the display.
• Do not modify the display structure or attach any panels or coverings without the
express written consent of Daktronics, Inc.
Support Structure Design
• Structure design is critical and should be done only by a qualied individual.
• It is the customer’s responsibility to ensure that the structure and the connectors are
adequate.
• The customer must also ensure the installation meets local standards.
• Daktronics is not responsible for installations, the mounting structure or its structural
integrity, or for the quality of the mounting hardware used to attach the displays
to the support structure. Structure and attachment must conform to all applicable
building codes.
Ventilation and Temperature Requirements
FuelightTM Petroleum Price digit displays are front ventilated. The display must NOT be
fully enclosed inside a support structure or sign or behind a sign face of plastic, glass, or
other material. The front of the display must be exposed to the air to allow for convection
cooling.
FuelightTM displays are designed to operate in ambient temperatures ranging from -40°F
to 120°F (-40°C to 49°C). However, overall sign structure design and ventilation should
keep the FuelightTM display cabinet interior below 140°F (60°C).
Items to consider when designing a sign package to house LED price displays include:
• Solar gain from the black face of the displays
• Solar gain from other sign cabinet surfaces
• Heat gain from electronics inside the displays
• Passive or active airow with adequate intake and exhaust areas
Daktronics is not responsible for high-temperature failure due to inadequate ventilation.

Mechanical Installation

See Section 4: Display Interconnections
(p�8) for Display Interconnection details.
4� Close and latch the doors of each section securely.
Installing the Display Inside a Sign
Cabinet
Design a space in the sign for the display so that the front
of the FuelightTM display cabinet is ush with the front of
the sign, allowing the doors to protrude 1/2" [12.5 mm].
Consult DWG-1154438 for more detailed information
regarding sign cabinet requirements. Use the display shop
drawing to locate mounting holes used in this installation
type.
1� Lift the display into the support structure. Refer to
Figure 5.
Note: Daktronics assumes no liability for display
damage or injury resulting from incorrect setup
or incorrect lifting methods.
2� Use 3/8-16 bolts and the four mounting holes in each
section to attach the display to the sign cabinet.
Actual site demands will dictate variances and
appropriate mounting methods.
3� Repair and seal any unused openings in the sign
structure.
Note: Openings greater than 1/2″ (12.7 mm) in
diameter require a metal patch secured
by screws or rivets and caulked with non-
hardening caulk. Smaller openings may be
sealed with non-hardening caulk.

3 Electrical Installation
Important Notes:
• Only a qualied individual should terminate power and signal cable at the display.
• All proposed changes must be approved by Daktronics engineering staff, or the
warranty will be void.
Electrical installation consists of routing power to the power supply each display face.
Each Shop Drawing shows details on installation and access for electrical connections.
Refer to the notes on the appropriate Shop Drawing for the electrical requirements for
that size of display.
The front panels of Daktronics FuelightTM displays are hinged to allow access to the digits,
cabling, and other electronic components. See Access Internal Components (p�7) for
cabinet access details.
Note: Only qualied individuals should perform power routing and termination to the
display. It is the electrical contractor’s responsibility to ensure that all electrical
work meets or exceeds local and national codes. Improper installation could
result in serious damage to the equipment and could be hazardous to personnel.
Power Requirements
Do not connect displays to any voltage other than that listed on the display product
label. FuelightTM displays have a voltage input of 100-240 VAC and a frequency input of
50/60 Hz.
• The dedicated circuit can be shared among all components of the sign structure
(including FuelightTM displays and uorescent lighting), but not with other external
electrical devices (such as air compressors or island lighting).
• A dedicated circuit is dened as one hot, one neutral, and one ground wire.
• Maximum amperage will vary with the number and type of digit displays connected.
Note: Follow all local and national electrical codes during electrical installation.
Note: It is critical that the display circuit be fused at 15 A and that all conductors
used must be designed to pass a 15 A current in normal operation. Failure to
meet wiring and over-current protection device requirements may violate
local and national electrical codes and will void the display warranty.
• Size conductors of circuits delivering power to a Daktronics display according to local
and national electrical codes so that the power distribution systems can deliver full-
load power to the display while maintaining a voltage within 5 percent of the utility
nominal voltage.
Main Disconnect
Daktronics requires using a power disconnect switch with the display. Use a disconnect
so that all ungrounded conductors can be disconnected near the point of power
connection.
Locate the disconnecting means either in a direct line of sight from the display or so it
can be locked in the open position. This ensures that power is not reconnected while
service personnel work on the display.

Electrical Installation
7
Access Internal Components
The door of FuelightTM Petroleum Price displays is
secured by two slotted fasteners.
1� Release the fasteners by gently turning
them counter-clockwise with a at-head
screwdriver.
2� Open the doors using the knobs attached to
the display faces.
3� Open doors without knobs by gently pushing
the door outward from inside of the display.
4� The driver and power supply(s)
are attached inside the cabinet
to the display’s backsheet and
their locations vary between
display sizes. Refer to Figure 8
and Figure 9 for component
locations.
5� A breakout board for each digit
is located between the upper
digit segments.
Grounding
The displays are designed so the most sensitive components are isolated and a local
earth ground electrode is not required and is no longer recommended.
The displays still require a safety ground from the electrical service panel for the primary
power wires to comply with national electric codes.
Please note that local earth ground electrode requirements for other Daktronics products
remain unchanged.
Power Installation
Install Daktronics FuelightTM displays using a two wire plus ground circuit. Connect the
ground from the circuit to the grounding stud within each Fuelight display. Do not
connect neutral to ground at the disconnect or at the display, this violates electrical
codes and voids the warranty. Use a disconnect so that all ungrounded conductors can
be disconnected.
To connect power to the display:
1� Route the power cable into the display through one of the knockouts on the display’s
backsheet.
2� Use wire nuts or other appropriate hardware to connect power wires - hot (black)
and neutral (white) - to the power supply harness or pigtail.
3� Connect supply power ground wire to the grounding stud.
Note: Verify the power supply ground wire is connected to the to the grounding
stud.

Power-Up Self Test
A useful troubleshooting tool is the power-up self test performed by the host driver every
time the display powers up. If there is a problem, an error code, shown in the left column
of the table, will appear on the display.
Information Shown on Display Meaning of Information
E10 Temperature over 75°C – normal controller operation
E11 Temperature over 85°C – report this error message to
Daktronics Customer Service
Exx All other error codes relate to the display driver. Contact
Daktronics for more information or to order a new driver.
After the self test, each display is programmed with a default price that corresponds to
the line number for which it is addressed. Changing each
line’s price overwrites these defaults.
