display, a minimum height of above 6 feet is required. If mounting below the display, a minimum of 8
feet above ground and a minimum of 1 foot between the sensor and the display is required, as seen in
Figure 8.
Greater accuracy is obtained if grass is below the sign rather than concrete or some other material.
Use a 2 pair, individually shielded cable (Belden 5594, Daktronics part number W-1234) to
connect the sensor to the display controller. Maximum length is 1000 feet.
Follow these steps to mount the temperature sensor.
1. Run ½” conduit from the sensor location to the controller where the sensor cable is to be
attached. The cable must be routed through ½” metal conduit which should be earth
grounded to protect the sensor and controller from lightning damage.
2. Power down the controller where the sensor cable is to be attached.
3. Connect the cable to the temperature sensor terminal block as shown below. (Refer to
Drawing A-79410 for the location of the terminals.)
