SECTION 1 : Introduction
1.1 How To Use This Manual
This manual explains the installation, operation and maintenance of Daktronics Data Time
Series 50 Incandescent Time and Temperature Displays. It provides dimensions and guides
you in mounting, wiring and operating these displays. The manual is divided into mechanical,
electrical, operation and maintenance sections.
For additional questions regarding the safety, installation, operation or service of these displays,
please refer to the phone numbers listed on the cover page of this manual.
KImportant Safeguards:
1. Read and understand these instructions before installing.
2. Do not drop the control console or allow it to get wet.
3. Be sure the display is properly grounded.
4. Disconnect power to the displays when they are not in use.
5. Disconnect power when servicing the displays.
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. The manual refers to drawings by the last
five digits and the letter preceding them. In the example below, the drawing would be referred
to as Drawing A-69945. Each set of reference drawings will be inserted at the end of the
section which first references them.

TIME & TEMP DISPLAYS
SECTION 2 : Mechanical Installation
2.1 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. When mounted back-to-back, the maximum distance between displays cannot
exceed 24”. The interconnect harness for the slave unit is coiled up inside the cabinet of the
slave unit.
48” and 60” displays do not have the 24” maximum separation limitation. 48” and 60” displays
do not have the master/slave interconnect, only a controller signal cable.
2.2 Support Column Selection
Support column size is dependent on the height and total wind loading of the display and
advertising panels that make up the entire display. Column selection is critical and should be
done only by a qualified individual. Only pipe and square or rectangular tubing are
recommended for single column displays. Wide flange members have low torque resisting
properties and wind flutter may result. It is the responsibility of the insta ller to determine the
column size required to support all the components to be mounted.
2.3 Mounting Details
Reference Drawings: Display Mounting, Using Horizontal Angle.....Drawing A-72324
Display Mounting, Using U-Clamp................Drawing A-72325
Display Mounting, Vertical Angle...................Drawing A-72326
Drawings A-72324, A-72325 and A-72326 show suggested methods of mounting the
displays to columns. The display cabinet has a 1.25” external flange. It is the responsibility of
the installer to ensure the installation will adequately meet local standards. The mounting
hardware and method are also the responsibility of the installer. Any aluminum angle used for
mounting should be a minimum of 1/4” thick. Refer to the appropriate drawing in Section 1
for additional mounting details.
60” displays require a two (2) column mounting method unless additional horizontal support is
provided by the customer. Minimum center to center column spacing is 72”. Engineering of
additional support is the responsibility of the customer.

Knockouts for1/2” conduit are provided in the master display on either end of the display for signal and
power entrance. Refer to the appropriate drawing in Section 1 for dimensions. Figure 1 shows the
general electrical layout of an installation.
Figure 1: Installation Electrical Layout
3.1 Display Access
Access the inside of the display through the hinged lampbank to perform electrical installation.
The lampbank is held closed with 1/4-turn fasteners along the bottom. Release the fasteners
and swing the lampbank open. Cut the cable ties on the prop rod and secure the lampbank
open.

On a large display (36”, 48”, and 60”), the lampbank is in multiple doors. The internal
components are located under the far left door when viewed from the front.
Drawing A-57279 is an illustration of the termination panel. Drawing A-87841 shows the
controller and component access. The power connections are made on the power termination
panel located in the master unit. The signal connections are made directly to the display
controller. The controller is located in the master unit in an enclosure. The enclosure cover
must be removed.
3.2 Power Connection
Note : When power is run to the display, a disconnect switch or plug must be provided within
sight of the display. To maintain CSA listed display, use the supplied disconnect.
Refer to Drawing A-57279 and A-57319. Power is supplied to the display through the
terminal block labeled TB41. The service required for a single face display is 120 VAC.
Service for a 2V display is 120/240 VAC single phase. The display amperage is stated on the
display specification label. Follow the instructions below to connect power to the display.
1. Run power through conduit into the display through one of the knockouts provided and
route over to the termination panel.
2. Connect the white neutral wire(s) to position 2 “NEUT” on TB41.
3. Connect a 120 VAC line to position 1 “01 (120 VAC)” on TB41.
4. For a 2V display, connect the second hot line of the 120/240 VAC service to position 3,
“02 (120 VAC)” on TB41. (Do not use two lines of a 120/208 three phase Wye service).
Exceptions: For 48” and 60” models, power is run separately to each face. Both positions 1
and 3 of TB41 are needed for one face and must be connected to a 120/240 VAC single phase
service. Check the specification label on the display for amperage. Refer to Drawing A-
67341.
For a 12” 2V model, use a single 120VAC line and connect a jumper from position 1 to
position 3 on TB41.
3.3 Grounding
All power service must be supplied with an earth-ground wire. Use the following instructions
to properly ground the display:
1. Attach the ground wire to the earth ground lug in the termination panel marked with “Earth
Ground” (Drawing A-57279).
2. Attach the ground wire to a copper earth ground rod installed according to the National
Electrical Code. Do not ground to any steel columns supporting the display.
