2.4 Temperature and Light Sensor
Reference Drawings:
Time & Temp Power/Signal Hookup ....................................................... Drawing A-938369
Shop Drawings .....................................................................................Refer to Appendix A
All displays in the DataTime® series use a light sensor to regulate dimming functions and a temperature
sensor to collect and display temperature information. Both temperature and light-monitoring electronics are
located in the sensor housing, shown in Figure 2.
The Daktronics Controller Area
Network (CAN) Temperature/Light
Sensor is pre-installed in a protective
housing. The assembly includes the
sensor, mounting bracket, and cabling
with a quick-connect plug. Instructions
that follow describe the placement
and connection of the device. Review
the wiring diagram and connection
illustration in Drawing A-184840 before
beginning.
Dimming involves decreasing overall
display intensity, both for better display
viewing and to prolong LED life. Set the
brightness level highest during the day
to compete with daylight, and lower at night.

Recommendations and Requirements:
• First choice for the sensor location is a north eave or northern exposure, away from direct sunlight
and above grass. This location gives extra stability and accuracy to the sensor because of the
additional shade usually provided by a northern exposure.

Figure 5: Temperature Sensor
Mounted Under North Eave
• Second choice for locating the sensor is on the display itself, or somewhere on the display structure.
(This works best with light-colored displays.) Locate the sensor above, below, or on the northern edge
of the display to keep the sensor shaded as much as possible. Sensor readings are more accurate if
there is grass below the sign, rather than concrete or asphalt.
Things to Avoid:
• The sensor requires a location away from chimneys, air conditioners, vents, tar roofs, concrete, and
parking lots, all of which can cause abnormal temperature fluctuations and incorrect sensor readings.
For accurate readings under these conditions, keep a separation of at least 20-30 feet horizontally and
8 feet vertically between the sensor and the influential element.
• Locations that restrict air movement are also unsatisfactory.
• When a display has two faces, do not mount the sensor between the faces.
Connecting the Temperature Sensor
After properly locating the sensing device, follow these steps to connect it with the display:
1. The temperature sensor is equipped with outdoor-rated cable that has a four-pin quick-connect plug
on the end. Route the cable from the sensor to the back of display.
2. A four-pin quick-connect jack located on the back panel of the display connects the sensor cable to
the display. Refer to the Shop Drawing for the exact location of the jack on a particular model. Simply
plug in the sensor cable and tighten the connector collar to the display. A factory-installed internal
cable, runs from the sensor jack to the TB1 connector on the driver inside the housing.
Mechanical Installation 5
3. Secure any additional cable to prevent the quick-connect plug from being pulled out of the display
and to protect it from weather or vandalism.
Note: The temperature sensor is equipped with 25 feet (7.6 m) of cable. If necessary, the cable can be cut to
shorten and then be re-terminated. In addition, the cable can be extended by using a four-conductor shielded
cable to a distance of 750 feet (230 m). When not using the provided weather-resistant cable, the cable from
the sensor to the display needs to be in conduit.
Connection to the Sensor
If it is necessary to reconnect the wires to
the temperature sensor terminal block,
refer to Figure 6 and the table for the
correct connections.
Note: Make sure the power is off before
making any connections.
Connection from Sensor to the
Display Driver
If the distance from the temperature
sensor to the display is greater than the
provided 25 foot (7.6 m) cable, connect a 4-conductor shielded
cable from the sensor to TB1 on the display driver board.
1. The display’s power must be OFF when attaching the
internal sensor cable to the host driver.
2. Connect the temperature sensor to the terminal
block (TB1) on the host driver. Refer to Figure 7
and the table for the correct
connections.

Section 3: Electrical Installation
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. Improper installation
could result in serious damage to the equipment and be hazardous to personnel.
3.1 Preparing for Power/Signal Connection
Reference Drawing:
Time & Temp Power/Signal Hookup ....................................................... Drawing A-938369
Electrical installation consists of the following process:
• 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 display location.
• Routing the control signal cable from the control location to the display location.
Drawing A-938369 provides detailed instructions for power and signal connections for time and temperature
displays, including connection of the temperature sensor and connections between host and client displays.
Refer to this drawing before completing any part of the electrical installation.
3.2 Power Connections
Daktronics DataTime® displays have removable or hinged front panels that allow access to the digits, cabling,
and other electronic components.
DataTime® outdoor displays require a dedicated, 120 V circuit (or 230 V for international use) for incoming
power. The display itself has no breakers or fuses.
WARNING: The display circuit must be fused at 15 A, and all conductors must be designed to pass a 15 A
current in normal operation. Failure to meet wiring and over current protection device requirements is a
violation of the National Electrical Code and will void the display’s warranty.
Displays MUST be grounded according to Article 250 of the National Electrical Code and according to
Daktronics specifications or the warranty will be void. Daktronics requires a resistance-to-ground of 10 ohms
or less.
The contractor performing the electrical installation must verify ground resistance. Technicians from
Daktronics Sales and Service offices can also provide this service.
Proper grounding is necessary for reliable equipment operation. It also protects the equipment from
damaging electrical disturbances and lightning. Drawing A-938300 illustrates where to connect the ground
wire at the driver enclosure.
Electrical Installation 7
Important points about grounding:
• Follow local and national codes: The material of an earth-ground electrode differs from region to
region and from conditions present at site. Consult any electrical codes that apply.
• Support structure cannot be used as an earth-ground electrode: Daktronics does not recommend
using the support structure as an earth-ground electrode; concrete, primer, corrosion, and other
factors make the support structure a poor ground.
• Note: The support structure may be used as an earth-ground electrode only if designed to do so. A
qualified inspector must approve the support structure and grounding methods.
• One grounding electrode for each display face
3.4 Power Installation
There are two types of 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. In this
circumstance, do not connect neutral to ground at the disconnect or at the display as this would violate
electrical codes and void the warranty.
Use a disconnect so that all ungrounded lines can be disconnect. The National Electrical Cod 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, observe the
following guidelines:
• 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.
3.5 Lightning Protection
Using a disconnect near the display to completely cut all current-carrying lines significantly protects the
circuits against lightning damage. For this system to provide protection, disconnect power when the display
is not in use.
Disconnect the DM-100 control console 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 DM-100 console’s circuitry.
Route power and signal cables into the display from the side or rear. There are 7/8" knockouts for 1/2" conduit
fittings on the sides of all DataTime® cabinets and on the back
panels. All power and signal wiring terminates at the driver
enclosure.
Open the display cabinet by turning the latches on the hinged
doors. To access the driver enclosure, open the access door and
remove the cover. Refer to the Shop Drawings for the access
location for the display.
Refer to Drawing A-938300 for a complete review of power and
signal connections for direct connection to the displays. Drawing
A-166216 provides connection specifications for the four-column
drivers used in all DataTime® Time & Temperature displays.
Power and signal connections, illustrated in Figure 8, are similar
for both drivers.
