After mounting the optional temp sensor, follow these steps to complete the electrical installation. A
2-pair, individually shielded cable (Belden 5594, Daktronics part number W-1234) is used to connect
the sensor to the controller.
1. Run ½
″
conduit from the sensor location to the controller within the display. The cable must be
routed through one-foot of ½
″
metal conduit that should be earth-grounded to protect the sensor
and controller form lightning damage.
2. Connect the cable to the temperature sensor terminal block within the temperature sensor as
follow:
Wire Color Terminal Block
Red V+
Green P
Black GND
White N
3. Install the mesh screen with the four screws enclosed.
4. Disconnect power to the display before attaching the cable
5. Connect the cable to the temperature sensor terminal block on the controlle r (TB7) per the
following table:
Wire Color Terminal Block TB7
(Temp In)
Pin 1 (+5)
Pin 2 (GND)
Pin 3 (Light +)
Pin 4 (Light -)
Green Pin 5 (Temp +)
White Pin 6 (Temp -)
Red Pin 7 (+5V)
Black & Shield Pin 8 (GND
OR Bare (shield) Pin 8 (GND)
To connect the temperature sensor to multiple displays (such as a double -face display):
