Shop Drawings................................................................See Appendix A

The MF Series cabinets contain two horizontal extrusions, two end plates, a
polycarbonate face, and a backsheet. The LEDs are all contained in one circuit board
that slides into grooves in the extrusions. Another circuit board attached to the LED
board has the transformers mounted to it.

Installation of the MF Series displays consists of the following steps:

1. Remove the backsheet by first unscrewing the two #6 screws on the bottom of

the display and then sliding the backsheet down and away from the display.

2. Knock out one of the two access holes, as shown in Drawi ng A-222256, from

the inside of the backsheet to the outside. This hole will be used to route pigtail
wires to the driver circuit of the display.

3. Attach the backsheet to the wall where desired. Two keyholes in the backsheet

allow mounting to two #10 screws.

2-2 Mechanical Installation

Section 3: Electrical Installation

Daktronics MF Series Status/Lane Indicator displays are ETL listed and tested to
CSA standards. Contact Daktronics with any questions regarding the testing
procedures.

Only qualified individuals should perform power routing and termination to the
display. It is the responsibility of the electrical contractor to ensure that all
electrical work meets or exceeds local and national codes.

3.1 Preparing for Power/Signal Connections

Reference Drawings:

Shop Drawings......................................................... Refer to Appendix A

MF-1000 Series Display Installation ............................Drawing A-222256

Electrical installation consists of the following processes:

• Providing power and ground to a disconnect near the display.

• Routing power and ground from the main disconnect to the display

enclosure.

• Connecting the ground to a grounding electrode at the display location.

Drawing A-222256 for displays in this series shows the locations of internal

components and electrical access holes. Refer to these drawings before making
power connections. Power terminates to the control board in the display enclosu re.
Termination is to be completed by the customer's electrician.

3.2 Power and Grounding Connections

Correct power and grounding installation is imperative for proper display operation.
The subsections that follow give details of display power and installation. Only
qualified individuals should attempt to complete the electrical installation. Improper
installation could result in serious damage to the equipment and could be hazardous
to personnel.

Power

Daktronics status/lane indicator displays have been designed for easy access to
components and to power.

Daktronics MF Series Status/Lane Indicator displays require a dedicated 120 VAC
circuit for incoming power. The display itself has no breakers or fuses.

Power conductors and conduit are to be sized and installed by the customer's
electrician. Knockout-type access holes for the conduit are
back plate.

The table below shows the circuit specifications and maximum power requirements
for each model in this series. Models are listed in order by size and display type.

Grounding

Reference Drawings:

Shop Drawings ........................................................Refer to Appendix A

Displays MUST be grounded according to the provisions outlined in Article 250 of
the National Electrical Code and according to the specifications in this manual.
Daktronics requires a resistance-to-ground of 10 ohms or less.

The contractor performing the electrical installation can verify ground resistance.
Technicians from Daktronics Sales and Service offices can also provide this service.

The display system must be connected to an earth electrode installed at the display.
Proper grounding is necessary for reliable equipment operation. It also protects the
equipment from damaging electrical disturbances and lightning. The display must

be properly grounded, or the warranty will be void. Refer to the shop drawings in
Appendix A for information on where to connect the grounding wire. Connection at

the driver enclosure terminal block is illustrated at the bottom of the drawing.

The material for an earth-ground electrode differs from region to region and may
vary according to conditions present at the site. Consult the Nation a l Electrical Code
and any local electrical codes that may apply. The support structure of the display
cannot be used as an earth-ground electrode. The support is generally embedded in
concrete. If it is in earth, the steel is usually primed, or it corrodes, making it a poor
ground in either case.

Power Installation

There are two considerations for power installation: installation with ground and
neutral conductors provided, and installation with only a neutral conductor provided.

3-2 Electrical Installation

These two power installations differ slightly, as described in the following
paragraphs:

Installation with Ground and Neutral Conductors Provided
For this type of installation, the power circuit must contain an isolated earth-ground
conductor. Under this circumstance, do not connect neutral to ground at the
disconnect or at the display. This would violate electrical codes and void the
warranty. Use a disconnect so that all hot lines and neutrals can be disconnected. The
National Electrical Code requires the use of a lockable power disconnect within sight
of or at the display.

Installation with Only a Neutral Conductor Provided

Installations where no grounding conductor is provided must comply with Article
250-32 of the National Electrical Code. If the installation in question meets all of the
requirements of Article 250-32, the following guidelines must be observed:

• Connect the grounding electrode cable at the local disconnect, never at the

display power enclosure.

• Use a disconnect that opens all the ungrounded phase conductors.

3.3 Lightning Protection

The use of a disconnect near the display to completely cut all current-carrying lines
significantly protects the circuits against lightning damage. The National Electrical
Code also requires it. In order for this device to provide protection, the power must
be disconnected when the display is not in use.

3.4 Manual Control Functions (Switch Inputs)

Reference Drawing:

Models MF-1001, MF-1002, MF-1003, and MF-1004..Drawing A-208524

MF-1000 Series Display Installation ............................Drawing A-222256

This is the simplest control scheme, suitable
for low cost applications where an integrated,
remote control system is not needed. Using the
switch, a display can show ‘OPEN’,
‘CLOSED’, ‘FULL’, ‘X’, or a diagonal arrow,
depending on the model. An optional three
way switch will give a blank display as well.
Refer to Drawing A-208524.

The signal will be sent using two wires from
the switch to the display. The switch is
switching 120 VAC between Lines A & B; it is not switching a signal. Refer to
Figure 3 and Drawing A-222256 for system layout.

Use 18 AWG or larger cable to connect the switch to the display as shown in
Drawing A-222256.

Figure 3: Manual Control Layout

3.5 Automatic Dimming Operation

The display’s brightness is automaticall y adjuste d by the use of a phot o cel l circui t .
The display brightness can also be adjusted be the potentiometer (POT) located on
the power supply. The POT controls the display’s brightness limit. Rotate the knob
clockwise to increase the display’s brightness limit and rotate it counter clockwise to
lower the display’s brightness limit.

4.1 Cabinet Specifications

Reference Drawing:

MF-1000 Series Display Installation ............................Drawing A-222256

Cabinets for the Daktronics outdoor LED digit displays are constructed of heavy gauge
aluminum. Refer to Drawing A-222256 in Appendix A for instructions on mounting the
cabinet.

4.2 Component Location and Access

Displays in the MF Series consist of three main components: the enclosure, the power
supply circuit board, and the display circuit board.

Displays are made up of a single circuit board that slides into grooves in the horizontal
extrusions of the enclosure.

The MF Series displays are side-access, meaning that the displays open from the side for all
service. Removing an end plate will allow access to all the internal components.

To remove an end plate and access components, complete the following steps:

1. Disconnect power to the display.

2. Unscrew the four #6 flathead screws on the side of the display that secure the end

plate onto the enclosure.

3. Carefully slide the panel out the open end of the display.

4. Disconnect all wires for easier access to the internal components.

4.3 Service and Diagnostics

Panel/Power Supply Circuit Replacement

The circuit board is the platform for the LEDs. Do not attempt to remove individual LEDs.
In the case of a malfunctioning board, replace the entire panel and power supply circuit.

Maintenance and Troubleshooting 4-1

To remove and replace a panel, follow these steps:

1. Disconnect power to the display.

2. Follow the steps in Section 4.2 to gain access to the panel.

3. Completely remove the panel/power supply circuit assembly from the display.

4. Locate the replacement panel and attach the wiring to this new panel.

5. Slide the replacement panel into the enclosure.

4.4 Troubleshooting

4.6 Daktronics Exchange and Repair & Return Programs

To serve customers' repair and maintenance needs, Daktronics offers both an Exchange
Program and a Repair & Return Program.

Exchange Program

Daktronics' unique Exchange Program is a quick, economical service for replacing key
parts in need of repair. If a part requires repa ir or replacement, Daktronics sends the
customer a replacement, and the customer sends the problem part to Daktronics. This not
only saves money but also decreases display downtime.

To participate in the Exchange Program, follow these steps.

1. Call the local Daktronics representative or the Daktronics Customer Call

Center: [phone] (toll free) or 605-697-4958. Choose option 2 to have a
Customer Service Coordinator order a new part.

2. When the new exchange part is received, mail the old part to Daktronics.

If the replacement part fixes the problem, send in the problem part that is being
replaced.

a. Package the old part in the same shipping materials in which the

replacement part arrived.

b. Fill out and attach the enclosed UPS shipping do cument.
c. Ship the part to Daktronics.

Maintenance and Troubleshooting 4-3

3. You will be billed for the replacement part immediately, unless you have a
qualifying service agreement in place.

In most circumstances, you will be invoiced for the replacement part at the time it
is shipped. This bill, which represents the exchange price, is due when you receive
it.

4. You must send the problem part to Daktro nics within 30 days.

If you do not ship it to Daktronics within 30 working days from the invoice date,
Daktronics assumes you are purchasing the replacement part outright with no
exchange. You will therefore be invoiced for the replacement part at the full
purchase price, with the balance due upon receipt. The second invoice represents
the difference between the exchange price (billed previously) and the full purchase
price of the part. If you return the exchange equipment after 30 working days from
the invoice date, you will be credited for the amount on the second invoice, minus
a restocking fee.

Note: Second invoice policies also apply to customers with qualifying service
agreements in place.

To avoid a restocking charge, return the part which has been replaced

5. If the replacement part does not solve the problem, return the part within 30
working days or you will be billed for it at full purchase price.

If, after you make the exchange, the equipment still causes problems, please
contact our Customer Call Center immediately. Daktronics expects
return of an exchange part if it does not solve the problem. The company also
reserves the right to refuse parts that have been damaged due to acts of nature or
causes other than normal wear and tear.

within 30 days of the invoice date.

immediate

Repair & Return Program

For items not subject to exchange, Daktronics offers a Repair & Return Program. To send a
part for repair, follow these steps.

1. Call your local Daktronics representative or the Daktronics Customer Call
