    6. Do not modify the displays or attach any panels or coverings to the displays without the written consent of Daktronics, Inc. The box below is an illustration of Daktronics drawing numbering system. The drawing number “7087-P08A-69945” is how Daktronics identifies individual drawings. This number is located in the lower right corner of the drawing.

  • Page 9: Mechanical Installation

    SECTION 2: MECHANICAL INSTALLATION Display Definitions Two configurations of displays are offered: single face displays and 2V displays. A single face display is a single-sided, stand-alone unit. A 2V display consists of two units – one master and one slave. The two sides of this display may be mounted at any angle between 0 and 180 degrees.

  • Page 13: Electrical Installation

    SECTION 3: ELECTRICAL INSTALLATION Knockouts for 1/2” conduit are provided in the master display on the left end of the display (front view) for signal, power and temperature sensor entrance. Refer to Drawing A-91840 in Section 1 for dimensions. Figure 4 shows the general electrical layout of an installation. Figure 4: Installation Electrical Layout Display Access Access the inside of the display through the hinged face panel to perform electrical installation.
  • Page 14 Figure 5: Display Components The power connections are made on the power termination panel located in the master unit (refer to Figure 6 for a close up view of the panel). The signal connections are made directly to the display controller. Both the power termination panel and the controller enclosure can be accessed by removing the 1/4 turn retaining screws in the cover (refer to Figure 7).

  • Page 15: Power Connection

    Power Connection Reference Drawings: Schematic, 13 LOC T&T ......Drawing A-80682 Note: When power is run to the display, a disconnect switch or plug must be provided within sight of the display. Refer to Figures 6 and 7. Power is supplied to the display through the terminal block labeled TB41.

  • Page 16: Temperature Sensor/Light Detector

    Figure 8: Handset and Enclosure Temperature Sensor/Light Detector The temperature sensor/light detector (optional) is mounted separately and requires a location away from the influence of chimneys, air conditioners, or vents which can cause abnormal temperature fluctuations. Usually a separation of at least 20-30 feet horizontally is required to achieve this.

  • Page 17: Eave Mounting Of Sensor

    The second choice for locating a temperature sensor is on the display itself, or somewhere on the display structure. A light-colored display is preferred in this application. Location of the sensor should be on a northern edge of the display to try to keep the sensor shaded. Greater accuracy is obtained if there is grass below the sign rather than concrete or some other material.

  • Page 18: Connection To Controller

    3.5.2 Connection to Controller A 5-conductor 18-gauge cable (Belden 8465, Daktronics part number W-1007) is used to connect the temperature/daylight sensor to the display controller. Maximum length is 1,000 feet. Install as follows: 1. Connect the cable to the temp sensor as shown in Figure 9 and route through 1/2”...

  • Page 19: Master/Slave Connection

    Master/Slave Connection The slave display is electrically connected to the master display by means of an interconnect harness provided in the slave display. This harness should be routed from the slave display into the master display using a conduit nipple or other appropriate method. When back-to-back, the displays can have a maximum separation of 24”...

  • Page 23: Operation

    SECTION 4: OPERATION This section outlines the operation of a Series 50 time and temperature display. This display uses a standard 16 column LED driver and a Series 50 controller built into the cabinet of the display. The controller is programmed using a handset which is stored at the base of the display. The handset has three push button switches which are used to set the time, price, and display function values of the controller (refer to Figure 8).

  • Page 24: Setting The Functions

    Setting the Functions The FUNCTION SET mode is used to adjust the 14 FUNCTION values of the display. These functions include such things as hold time and display sequence. To enter this mode, push the first button, labeled SET. When this button is pressed, the display will show an F1. Pressing the second button (FUNCTION) will advance through the 14 FUNCTION numbers.

  • Page 27: Function 13: Month

    This function sets the current date. Values of 1 through 31 can be programmed. The controller automatically adjusts for months with fewer than 31 days (including leap year). It is the user’s responsibility to make sure the correct date is programmed initially. If an incorrect value is programmed, the calendar will be miscalculated.

  • Page 28: Setting The Price Values

    Month 1-12 Year 90-99, 00-20 Setting the Price Values This display is capable of showing not only time and temperature but also two separate price values. Refer to Section 4.4.2 for different possible combinations. The price values are free format, which means that for either price, each of the four digits and the decimal point is set to exactly the character that is desired for that digit position.

  • Page 29: Switch Settings

    If the sensor is disconnected, the display driver will sense this and will not display any temperatures. When the sensor is reconnected, the display will again show any temperature values as selected by the Display Sequence. Therefore it is not necessary to change any settings on the display if the sensor is being disconnected for a short period of time (such as for replacement).

  • Page 31: Maintenance & Troubleshooting

    SECTION 5: MAINTENANCE & TROUBLESHOOTING IMPORTANT NOTES: 1. Display power must be turned off before any repair or maintenance work is done on the display. 2. Any access to internal display electronics must be made by qualified service personnel. This section outlines maintenance and troubleshooting for Series 50 Time and Temperature displays. The layout and operation of the display components are explained first.

  • Page 32: The Display Controller

    The driver has 16 jacks (one per column) for switching digit pixels. Figure 12 shows the pin assignments and color code for the plugs that mate to these jacks. The jacks are divided into two groups as follows: Master Digits: J1, J3, J5, J7, J9, J11, J13, J15 Slave Digits: J2, J4, J6, J8, J10, J12, J14, J16 Plugs from all the digits are connected directly into these jacks on the driver.

  • Page 33: Connectors

    5.2.1 Connectors The controller receives input from the temperature sensor (TB2) and handset (TB3) and sends out data to the driver (TB1). Power is brought into the controller on J1. Refer to Figure 10 for locations of these connectors on the controller. The following tables show the pin functions of the jack and terminal blocks.

  • Page 34: Status Indicators

    5.2.3 Status Indicators The LED indicators show the status of the display controller. These indicators can be used to determine controller problems and are located on the left side of the controller, beneath J1 (refer to Figure 10). Their function is as follows: PW2: Temperature Sensor/Light Detector Power (+5 volts).

  • Page 35: Controller Pixel Test

    Once the display is open, power can be turned ON again for troubleshooting purposes. Caution should be taken when troubleshooting with display power ON. Only qualified personnel should attempt this. 5.3.1 Controller Pixel Test The controller can be set to run a pixel test in two different ways: 1.

  • Page 36: Dimming

    5.3.3 Dimming 1. Dimming can be most easily checked during the day by covering the temperature sensor/light detector for a minimum of five seconds. 2. If this does not work, set the controller to Manual Dim and Manual Bright using Function #3.
