Component Description and Theory of Operation
4
LED Modules
The LED modules consist of a display panel and clusters of LEDs. Each module contains 64
clusters of LEDs, and each cluster is referred to as a pixel. The pixels create the digits seen
on the sign. The module receives data packets from the sign controller and then turns on
and off and sets the dimming level of the module’s pixels appropriately.
LED Diagnostics
A pixel test can be performed to test each pixel in the sign for proper operation. The Pixel
Test in the Vanguard
®
Central Controller software performs the check and monitors the
results. Refer to Vanguard
®
Software Help File [F1] .
Power Supplies
The power supply mounts to the cabinet truss behind module A102. The power supply
provides the necessary voltage to the LED modules and sign controller.
Cooling
An exhaust fan and filtered air intake vent are mounted on the back of the sign for
cooling during warm weather. The fan turns on during warm weather to circulate the air
behind the LED modules. A thermostat inside the sign controls the fan.
Light Sensors
The light sensor consists of one (1) photocell at one location. The sensed lighting
conditions are converted to signals that transmit to the sign controller through the CAN
lines. The sign controller then adjusts the LED brightness levels appropriately.
