Each module contains drive electronics that receive data packets from the Vanguard control board and lights the ®... -
Page 8: Traffic Cabinet
Traffic Cabinet Power Supplies The power supplies provide voltage to power the modules. Multiple power supplies provide power redundancy. If one power supply in the group fails, the other supports the full power load, preventing power failure to the modules. Isolation Board One isolation board mounts to each power supply. -
Page 9: Cabinet Heater
Cabinet Heater The heater fan is located at the bottom of the traffic cabinet. The fan, thermostat, and heater regulate the temperature within the traffic cabinet, ensuring internal components operate at ideal temperatures. A UPS contains batteries and an inverter. If the utility AC power fails, the UPS powers the Vanguard Field Controller and communication equipment for a limited amount of time. -
Page 10: Mechanical Installation
Use appropriate hardware to support the weight of the display. Have a qualified engineer inspect the mounting structure. Note: Daktronics is not responsible for mounting methods or the structural integrity of support structures provided by others. After installing the display, inspect the top and sides of the display for any openings that may allow moisture to enter the display. -
Page 11: Electrical Installation
Electrical Installation Getting Started Daktronics recommends that a separate circuit be run to the electronic display(s) to isolate it and prevent any issues that could be caused by line voltage fluctuations or high frequency noise on the power line caused by other types of equipment. A separate circuit also makes display maintenance and troubleshooting easier. -
Page 12: Display Termination
To make AC power connections at a traffic cabinet: 1. Remove the panelboard cover to reveal the lugs. 2. Route the power cables through the bushing and into the panelboard. 3. Terminate each hot wire at L1 and L2, neutral wire at neutral ground bar lug, and ground wire to the ground bus bar in the panelboard. -
