After mounting the optional 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 from lightning damage.
2. Connect the cable to the temperature sensor terminal block within the temperature sensor as
follows:
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 controller (TB7) per the
following table:
Wire Color Terminal Bock TB7
(Temp In)
Pin 1 (+5V)
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):
Wire Color Display 1 TB7 Display 2 TB7
Green Pin 5 (Temp +) Pin 5 (Temp +)
White Pin 6 (Temp -) Pin 6 (Temp -)
Red NC NC
Black NC NC
Note: GND and +5V (Red and Black) are connected from the temp sensor to the first display
only. The Red and Black wires must not be connected between controllers in additional
displays.
