Introduction
2
Figure 2 shows an FL-4500 Series Petroleum Price display.
The Fuelight™Series includes
standard petroleum price displays.
In the United States, the displays
employ a 9/10 fraction.
The drop-in displays are designed
for installation in an existing or
custom sign structure. Fuelight™
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 Fuelight™displays
to illuminate numeric digits.
Fuelight™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).
A typical display system is shown in Figure 3.
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.

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.
Sign 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 sign 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 local
and national building codes.
Ventilation and Temperature Requirements
Fuelight™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.
Fuelight™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 Fuelight™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.
Display Installation
1� Remove existing displays.
2� Provide a rectangular opening in the sign structure to accommodate the Fuelight™
Petroleum Price display. Refer to the Shop Drawing for cutout dimensions.
3� Ensure there is a continuous minimum depth of 2.5" (64 mm) within the cutout to
accommodate the body of the Fuelight™display.

Mechanical Installation
4
4� Hand lift displays into the sign structure. Figure 4 shows a display being inserted into a
sign structure.
Note: Daktronics assumes no liability for display damage or injury resulting from
incorrect setup or incorrect lifting methods.
5� Drill through the front anges of the cabinet to attach the display to the structure
using appropriate hardware for site conditions. Refer to Figure 5. Actual site demands
will dictate variances and appropriate mounting methods.
6� Repair and seal any unused openings in the sign structure.
Note: Openings greater than 1/2" (13 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
Electrical installation consists of routing power to the power supply located in 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 Fuelight™displays are hinged to allow access to the
digits, cabling, and other electronic components. Refer to Access Internal Components
(p�6) for cabinet access details.
Warnings and Disclaimers
• Ensure that all electrical work meets or exceeds all local or national electrical codes.
• Provide the required power to the display as listed on the product labels,
specications, or site-specic riser drawings. The conductor size may vary based on
the length of the power run.
• Consider implementing a separate circuit for the display using an isolation
transformer or dedicated transformer.
• Daktronics assumes no liability for any issues caused by line voltage uctuations or
other improper power conditions.
Important Notes:
• Only qualied individuals should perform power and signal routing to the display and
termination at the display.
• Daktronics engineering staff must approve all proposed changes, or the warranty will
be void.
• Improper installation could result in serious damage to the equipment and could be
hazardous to personnel.
• 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% of the utility nominal
voltage.
Power Requirements
Do not connect displays to any voltage other than that listed on the display product
label. Fuelight™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 Fuelight™ 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 varies with the number and type of digit displays connected.
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.

Electrical Installation
6
Main Disconnect
Daktronics requires installation of a power disconnect switch with the display so 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.
Access Internal Components
The door of Fuelight™Petroleum Price displays is secured by two slotted fasteners.
1� Release the slotted latches by gently turning them counter-clockwise with a at-head
screwdriver.
2� Open the left door using the knob attached to the display face.
3� Open the right door by gently pushing it outward from inside of the display.
Note: Smaller displays may only have one door.
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 6 for
approximate component locations.

Grounding
FL-3000 and FL-4500 series displays do not require a local earth ground electrode�
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 Fuelight™displays using a two wire plus ground circuit. Connect the
ground from the circuit to the grounding stud within each display. Refer to Figure 7.
Do not connect neutral to ground at the disconnect or at the display as this violates
electrical codes and voids the warranty. Use a disconnect so that all ungrounded
conductors can be disconnected.

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 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.
