Power

Power is automatically applied when the power cord is connected to an AC source. When AC power is applied, the switcher performs a self-test that blinks all of the front panel LEDs and then lights only the LED for the previously selected output and the tied input. The self-test also displays the model name, part number, and the firmware version in the LCD display. After approximately 2 seconds, the LCD reverts to its default display cycle, alternating between two displays; one showing the inputs selected for outputs 1 and output 2, and the other showing the selected output rates (figure 3-6). An error-free power up self-test sequence leaves all of the LEDs, with the exception of the selected output’s and input’s LEDs, off and the LCD cycling through the default displays.

The selected inputs for output 1 and output 2, the picture adjustments, and other current settings are saved in nonvolatile memory. When power is applied, the latest configuration is retrieved.

On figure 3-6 and all other flowcharts in this chapter, solid lines indicate screen changes initiated by the operator. Dashed lines indicate screen changes that are the result of a timeout function.
