1.4 Product Overview

DataMaster Gasoline Price displays are part of a family of Daktronics products designed for easy installation, readability, and reliability. Microprocessor control assures consistent operation and accuracy. The Gas Price display is illustrated in Figure 3 below.

The DataMaster Series includes:

The Gasoline Price displays are available in two styles, a full-cabinet model designed for standalone use (DF-1020), and a front-insertion, or “drop-in”, model designed for installation in an existing or custom sign (DF-1021).

DataMaster displays use light emitting diodes to illuminate their numeric digits. (Light emitting diodes, or LEDs, are tiny, solid-state components that use a semiconductor to transform electrical current into light; they are high-intensity, lowenergy lighting units.)

The displays feature highly visible PanaView (The front-insertion Gas Price model is available with 13", 18" and 24" digits.) All DataMaster displays are configured with red or amber LEDs.

Because of their LED technology, the displays consume little power, some barely more than a household lamp. Power usage for individual displays in this series is a maximum 300 W. All models have a 120 V power requirement.

1.5 Model Names

Daktronics displays, video screens, and scoreboards are differentiated by their model numbers. The displays described in this manual all carry the two-letter prefix, DF-, which indicates that they are DataMaster models. The letter D indicates that they are numeric displays; the letter F indicates LED technology.

In the outdoor LED display series, typically the first set of numbers following the prefix identifies the series or product line, while the second set of numbers refers to digit height. A final letter denotes digit color. With Model DF-1020-13-A, for example, 1020 identifies the Gas Price full-cabinet line, and 13 signifies that the display’s primary digits are a nominal 13" tall. In the example, the letter A signifies that the digits are amber, while R would indicate red LED digits.

Another designation often used with the Model DF-1021 Gas Price display is an M or an S; those letters indicate that the display is either a master or a slave unit.

Section 3: Mechanical and Electrical

Installation

Mechanical installation typically consists of installing concrete footings and steel beams and mounting the display and any accompanying panels to the beams.

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 driver/power

enclosure.

 Connecting the display ground to a grounding electrode at the sign location.  Routing the control signal cable from the control location to the sign location.

3.1 Mechanical Installation

Reference Drawings:

Mounting Method, Flag Style, One Pole......................Drawing A-166139

Mounting Method, Single Line on One Pole................Drawing A-166142

While DataMaster outdoor digit displays are designed for wall or pole mounting, every installation will be different. Actual site demands will dictate the appropriate mounting method. Most DataMaster models have fully finished exteriors, for example, but other models are designed to be inserted into an existing sign cabinet and require a custom installation.

The engineering drawings referenced above detail a number of mounting methods, from a single display on a single column support to multiple displays stacked above one another in a two-pole installation. The drawings include welding and hardware notes that will be applicable for most installations.

Note: The drawings suggest mounting methods and are not to be considered as specifications for construction. The actual mounting hardware and structural design must be specified by a qualified engineer.

Lifting the Display

Model DF-1020 displays are shipped equipped with 3/8" eyebolts that are used for lifting and positioning the modules. Eyebolts are located along the top outer edges of the cabinet. Model DF-1021 drop-in displays are not so equipped.

Mechanical and 3-1 Electrical Installation

Daktronics strongly recommends using a spreader bar, or lifting bar, to lift the display. Using a spreader bar ensures that the force on the eyebolts is straight up, minimizing lifting stress. Figure 4, below, illustrates two lifting methods.

Figure 4: Lifting the Display

The illustration shows both the preferred method (left example) and an alternative method (right example) for lifting a display. Be sure to use every lifting point provided.

Note: Daktronics assumes no liability for display damage or injury resulting from incorrect setup or incorrect lifting methods.

Eyebolts are intended for lifting during installation o nly. Do not attempt to permanently support the display by the eyebolts.

In installations in which an ad panel or some other display section may be added to the base display, the lower section is installed first and secured to the support beams, and then the upper section is placed atop or above the lower sign section and attached to the beams. There may be cables extending from the top of the lower section. Guide these cables into the hole in the bottom of the upper section for later connection.

Installers may remove the lift eyebolts once the display is in place. On models with 13", 18" or 24" digits, thread digits, install

/2"-13 bolts in the holes.

/8"-13 bolts into the holes. On models with 36" or 48"

Daktronics DataMaster displays have been designed for easy access to components, and the power and control signal hookup has been simplified. Front panels are removable or hinged to allow access to the digits, cabling, and other electronic components.

Correct power installation is imperative for proper display operation. The subsections that follow give details of display power installation. Only qualified individuals should attempt to complete the electrical installation; untrained personnel should not attempt to install these displays or any of the electrical components. Improper installation could result in serious damage to the equipment and could be hazardous to personnel.

The DataMaster outdoor displays require a dedicated, 120 V circuit for incoming power. The display itself has no breakers or fuses.

WARNING: 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 overcurrent protection device requirements is a violation of the National Electrical Code

and will void the display warranty.

Refer to the DataMaster display schematics listed above and to the chart in Section 2 to determine circuit specifications and maximum power requirements for the models described in this manual.

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 recommends a resistance-to-ground of 10 ohms or less.

Mechanical and 3-3 Electrical Installation

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 schematics, Drawings A-165028, A-177935, and A-179599, or the driver reference, Drawing A-184918, for information on where to connect the grounding wire. Connection at

the driver enclosure terminal block is illustrated at the bottom of Drawing 184918.

The material for an earth-ground electrode differs from region to region and may vary according to conditions present at the site. Consult the National 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, and 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. 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 neutral 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 driver/power enclosure.

+ Use a disconnect that opens all of the ungrounded phase conductors.

Mechanical and 3-5 Electrical Installation

To gain access to the driver enclosure, open the access door and remove the cover from the enclosure. Refer to the electrical specifications drawings for the access location for your sign.

Connect the power and signal cables at the appropriate locations on the driver enclosure panel, as shown in Drawing A-184918.

The power feeder circuit connects directly to a terminal block in the driver enclosure. The block is located in the bottom center of both types of driver enclosure. Refer to the driver illustrations and the schematics, Drawings A-165028, A-177935 and A-179599, for wiring details.

Route signal cabling to the terminal block on the lower left edge of the enclosure (see Figure 5). The connections are labeled to permit easy installation. (In the 16column enclosure, the signal block is at bottom center.) For signal cable, Daktronics recommends 2-pair shielded cable, 22 AWG (Daktronics part number W-1234).

Host/Client and Master/Slave Definitions and Address Settings

Reference Drawings:

One driver at each sign installation is designated as the “host driver”. This driver receives its signal directly from the controller on the Signal In terminals, and it is the only driver that is connected to the light/temp sensor. The Sign al Out terminals are used to connect to “client drivers”.

Select the host driver by inserting the Protocol 4 plug into the 5-pin protocol jack (J20.) For protocol jack location, refer to the driver specifications drawings listed above.

The 12 V DC terminals connected to the host driver (see “Signal Connections” in Figure 5) run to the controller junction box. This output is used to power the DataMaster 100 controller.

All other drivers in the display system are client drivers. These drivers receive signal from the host driver on the Signal In terminals and can re-drive this signal to other “client drivers” on the Signal Out terminals.

Some multiple-module signs use “slave displays”. These displays do not contain a driver and may use either the client or host digit outputs. Refer to Drawing A- 168376 for an illustration of the client/host driver and master/slave display setups.

The address of each driver is set using the address jack (J19), and the address setting is based on that driver's position in the sign or display system. If a single-line sign is

3-6

Mechanical and Electrical Installation

used, the address will typically be address “1”. This is the default addr ess plug that is

shipped with each display. In a multiple-module display, the address plug determines

which line of information is shown on the drivers' digits. The address plug for each

line is included in the address plug kit, if applicable.

3.4 Light Sensor Installation

Reference Drawing:

Light Sensor Installation, G3........................................Drawing A-183775

Displays in the DataMaster series use a light sensor to regulate sign dimming

functions. (Dimming involves decreasing overall display intensity, both for better

display viewing and to prolong LED life. The brightness level should be highest

during the day to compete with daylight, and lower at night.) Use Drawing A-

183775 and the following instructions to install the light sens or in your DataMaster

Gasoline Price display. If the sign or sign system has more than one display, install

the light sensor in the host display only.

1. Remove the screws on the front

of the display and open the hinged access door.

2. Locate and remove the

plastic plug from front panel of the display, as shown in Figure

6. The location of the plug varies by model. Refer to the mechanical specifications drawings for model-specific information.

3. There are two 6-32 studs above

and below the plughole. Position the internal light sensor assembly on the studs, with the clear lens toward the front of the cabinet and the cable at the bottom. Secure the sensor with the plastic wing nuts provided with the assembly kit.

4. Route the signal cable to the driver and insert the 6-postion plug into the

mating jack on the driver, TB1.

5. Close the hinged access doors and replace the screws.

IMPORTANT NOTES:

1. Disconnect power before doing any repair or maintenance work on the display!

2. Allow only qualified service personnel access to internal display electronics.

3. Disconnect power when not using the display.

4.1 Cabinet Specifications

Cabinets for the Daktronics outdoor LED digit displays are constructed of heavygauge aluminum. Exact dimensions and weights for each model are listed in the chart in Section 2. Hinged panels for servicing digits and indicators and for component access are detailed in each model's mechanical specifications drawing.

4.2 Component Location and Access

For the front-access modules in this series, all internal electronic components and digits can be reached by opening one of the hinged access doors on the front of the display. Each door swings outward when the two screws on the display face panel are removed, as shown in Figure 7. For front and opened views of the displays, refer to your model's electrical and mechanical specifications drawings, listed in Sections

2.1 and 2.2.

Figure 7: DataTime Time and Temp Display with Door Panels Open

Maintenance and 4-1 Troubleshooting

Component placement varies slightly with each DataMaster model; consult the model-specific mechanical drawing to determine the layout for your display.

Note: Disconnect power before servicing the display! Disconnect power, too, when the display is not in use. Prolonged power-on may shorten the life of some electronic components.

Replacing a Digit

The digit circuit board, the platform for the LEDs, is mounted to the back of the digit panel. Do not attempt to remove individual LEDs. In the case of a malfunctioning board, replace the entire digit panel. Refer to Figure 8 below.

To remove a display digit, follow these steps:

1. Open the digit panel as described in the preceding section.

2. Disconnect the power/signal connector from the back of the digit. Release

the connector by squeezing together the locking tabs as you pull the connector free.

3. The digits are secured to the inside of the panel with fixed machine screws,

spacers, and push nuts. Remove the nuts and lift the digit off the standoff screws. (The push nuts can be removed in several ways, but Daktronics recommends using a

/32" nut driver.)

4. Position a new digit over the screws and tighten the nuts.

5. Reconnect the power/signal connector. Note: This is a keyed connector, it

6. Close and secure the digit panel and test the display.

Replacing a Digit Segment

When a digit malfunctions, in most cases it is necessary to replace the entire digit circuit board. Some larger digits (24", 36", 48"), however, may be constructed in segments, as shown in Figure 9 and it may be possible to make repairs by removing only the defective segment. As with smaller digits, the digit segment circuit boards are mounted to the back of the digit panel. Do not attempt to remove individual LEDs.

To remove a digit segment, follow these steps:

1. Open the digit panel as described

2. Disconnect the 2-pin power/signal

3. The individual segments are secured to the inside of the panel with fixed

In the display, the LED drivers perform the task of switching digits on and off. Refer to Drawings A-166216 or A-184475 for a complete listing of driver connector functions and wiring pin numbers.

DataMaster Gas Price displays may use 4-, 8-, or 16-column drivers, depending on the model and size of digits. Each 16-column driver has 20 or more connectors providing power and signal inputs to the circuit, and outputs to the digits and indicators. The following table describes connector functions for a 16-column driver. (Major functions are the same on 4- and 8-column drivers.)

Output connectors 1 through 16 each have nine pins. Pin 7 provides power (hot) to the digit or indicators wired to that connector. The other eight pins provide switching connections.

The display line controlled by the driver is set with jumper wires in the 12-p in address plug inserted in jack J19. All DataMaster displays ship with a “Line 1” plug installed.

4.5 Segmentation and Digit Designation

Reference Drawing:

Segmentation, 7 Segment Bar Digit ..............................Drawing A-38532

In each digit, certain LEDs always go on and off together. These groupings of LEDs are referred to as “segments”. Drawing A-38532 illustrates digit segmentation. It also details which connector pin is wired to each digit segment and the wiring color code used throughout the display.

The component locations drawings in Section 2 specify the driver connectors controlling the digits. Numbers displayed in hexagons in the upper half of each digit, as shown in Figure 10, indicate which connector or connectors are wired to that digit. (Larger digits, like the 36" digits shown in Figure 10, are each wired to two connectors.)

4.6 Troubleshooting

This section lists potential problems with the display, indicates possible causes, and suggests corrective action. This list does not include every possible problem, but it does represent some of the more common situations that may occur. (Refer to the appropriate manual for a list of potential problems with add-on or separately mounted message centers.

Symptom/Condition Possible Cause

Garbled display

Digit will not light

Segment will not light

Segment stays lit

Data appears in the wrong place on the display, wrong data on a particular line of the display

 Internal driver logic malfunction  Control console malfunction

 Black wire to digit broken  Poor contact at driver connection  Driver malfunction

 Broken LED or connection  Driver shift register failure  Broken wire between driver and digit  Poor contact at driver connector

 Driver shift register failure  Short circuit on digit

 Incorrect address settings on drivers

(Refer to “Power On Self-Test” in the following section, and consult tables to set correct addresses.)

Some DataMaster displays have their own built-in troubleshooting mechanism. Failures that may occur in the display driver are described using codes. In the event a sign malfunctions, a failure code registers by displaying an “Ex” value on the first two digits of the display. “E” simply indicates an error, and the letter “x” represents the actual code number. Refer to the following table for a description of each failure code and for possible solutions.

Note: The LCD screen on the DataMaster 100 controller will not show the failure codes described in the table below. Failure codes will only be displayed on the DataMaster sign.

Maintenance and Troubleshooting

Failure Code Description Possible Solution

E1 Protocol Setting Error: There is an

unsupported driver protocol setting.

E2 Time Error: There is no valid time

stored in the driver; it may be a failure of the real-time clock on board or other timekeeping device.

E3 Temp Error: There is no response

from the temp sensor or light sensor, or general temp sensor failure.

E4 No Message Error: This code is

shown when there are no messages downloaded to the display

E5 No Line Number Selected Error:

The driver for this line has a Protocol 4 plug installed in J20, but there is no address plug installed in J19.

Check the value set in the protocol plug of the driver (J20).

Set the time in the display using the Set Time menu option on the DataMaster 100 controller.

(DataTime Time & Temp displays only)

Check the temp sensor location and verify all connections. Refer to the instruction sheet for the CAN Temperature/Light Sensor mounting, ED13364.

Note: The temp sensor takes approximately 10 seconds to initialize on power-up. The sign will display this error until initialization is complete.

Download a new message to the display using the <

> key on the DataMaster

Power On Self-Test:

A useful troubleshooting tool is the power on self-test the host driver performs every time it powers up:

+ If the signal wiring between each controller is correct, the first two digits of

each driver will display “Ad” momentarily, and the first digit will then flash three numbers indicating the decimal address that is set with the address plug in J19. (If a client driver displays “A <number>,” followed by “P

Maintenance and 4-7 Troubleshooting

<number>,” it is not receiving “signal in,” and is performing its own selftest.)

+ Next, the first two digits of each line will display “Lx”, where “x” is the line

number that the driver is set to control (set with address plug).

+ Finally, each line will display “1234…” according to the column number of

each of its digits. Every line should show “1” on the left-most digit, and all digits should be numbered consecutively from left to right. If this is not the case, either the wrong address plug is installed, or the driver or digit harness is connected incorrectly.

If there is no address plug in the host driver, the host driver will display “E5,” and all client drivers will continually cycle through the power on self-test.

4.7 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. The control console should also be disconnected from power and from the signal j-box when the system is not being used. The same surges that may damage the display's driver can also damage the console's circuit.

Typically, the j-box is mounted to the display pedestal or column support, and the controller connects with the box via TIA/EIA-232 signal cable (formerly RS-

232). The controller draws its power from the display itself. Refer to Drawings A- 175342 and A-164988 for complete details on both indoor and outdoor directwire installations.

Signal from the junction box enters the sign and travels to the first display driver over 2-pair, shielded signal cable. The 22

Figure 12: DataMaster 100 Controller

with Signal Cable

AWG cable must be enclosed in conduit. Re-driven signal travels from the driver of the first display to the driver of the next over another line, also 22 AWG shielded cable in conduit. The process repeats for as many displays as there are in the system.

Once instructions have been input into the display, the driver's memory retains the data, and the controller can be unplugged. The sign will continue to operate on the stored information.

Signal cabling is similar for systems where the DataMaster displays will be operated remotely from a building location, except that the controller requires a wall pack transformer. The transformer plugs into both the hand-held controller and into a 120 V AC outlet. The DataMaster controller also connects to a junction box to send signal to the display, but the j-box will be located within the store or office. The control location can be up to 2000 feet from the actual sign.

The operator changes the display by entering current prices, rates, and operating instructions on the keypad of the DataMaster controller. For complete details on sig n operation, refer to Section 6.

5.3 Controller Signal Connection

This section provides information on the setting up the signal connection between the DM-100 and DataMaster Gasoline Price displays.

Reference Drawing:

System Riser Diagram; Control Combinations.....Drawing A-164988

The DataMaster displays may be controlled from a location inside a building, or from the base of the display, depending on customer preference. Drawing A-164988 and the subsections that follow provide greater detail on both installations using signal wire.

Wire Control from the Base of the Sign

This control option, illustrated in Figure 13, permits operation of the sign from the base of the display. The controller is connected to an outdoor junction box mounted on the display pole, which routes the signal to the sign through one 2-pair cable, 22 AWG. Cable is in conduit where required.

This control option does not require the controller to be connected to a power outlet. In this configuration, the DataMaster 100 uses the sign as a power source.

To operate the DataMaster display using this setup, connect the 9-pin to 9-pin cable from the DataMaster controller to the 9-pin j-box mounted on the display pole.

Figure 13: Wire Control from Base of Sign

Wire Control from a Building Location

This control option, illustrated in Figure 14, permits operation of the sign from an indoor control location. The hand-held controller is connected to an indoor junction box (j-box), which routes the signal to the sign through one 2-pair cable, 22 AWG. Cable is in conduit where required.

Section 7: POS Interface Installation and

Operation

A Point of Sale (POS) interface option is available with DataMaster LED Gasoline Price Displays. Displays with this option automatically update when product prices are changed in the POS. Displays with the POS interface option will be supplied with a POS Interface Kit (0A-1279-0400 for Gilbarco G-Site).

BEFORE YOU START:

1. Ensure that the POS system has a price sign output port, and refer to the POS

manuals to enable and/or configure the port.

2. Locate the parts in the list below.

7.1 Hardware installation:

1. Locate the following parts: a) POS Interface Kit containing:
