4 Operation
4.1Startup and Reset Procedure
When the CXC is powered-up or reset, it will first perform a 15-second self-test before displaying the Cordex logo and various identification messages. The three front-panel LED’s will illuminate temporarily, but will extinguish after the system has finished its self-test. Next, the GUI will display the power system’s parameters during Normal operating mode, see Figure 2.
4.2Normal Operation
This is the default-operating mode or “home page.” The GUI displays system status information and monitors all input channels.
Active areas to tap and activate are noted below:
Mode Status
Rectifiers Information
Converter Report may also be accessed via this active area
Alarm condition icon
Priority icon
Software Version
Home Page Icon, tap to login
Analog Signals Display
Alarm Indication

4.2.1Activation/Tapping
Each active area is touch sensitive and responds better to a stylus suited for this purpose; i.e. PDA type.
The Analog Signals Display on the home page will show two lines of text for system voltage and current by default (Figure 2). Tap this active area to decrease the font size for four lines of text showing the system values and the corresponding labels (Figure 3). The large font reappears after 20 minutes of inactivity (no user input); otherwise tap again to enter a new window of operation (Figure 10) or select a different active area as required. Refer also to 5.1.3.
The arrows beside the system values enable the user to return to the larger font of the normal (default) home page
The display also returns to the default page when the user logs out
from the menu.
A new window of operation will open for the active area selected, whereupon:
•Buttons may be tapped to evoke commands.
•Lists or pull-down menus enable item selection.
•Sliders and scroll bars may be used for navigation.
•Pop-up windows may appear from selected items; to be cleared as the user follows the prompts.

4.2.2LCD Touch Screen Calibration
A touch screen calibration page may be evoked from the user interface default operating screen: Perform a diagonal action or "swipe" from the top right area of the LCD to the bottom left area:
CAUTION: Do not use a pen, pencil or other sharp object to tap on the CXC screen. This will scratch the screen and may void the warranty.
Figure 4–Begin LCD touch screen calibration (default operating screen)
When the calibration screen appears, tap on the center of the first target within 20 seconds to complete this step:
Tap on the center of the first target
(top left area of the screen)
Calibration will be ignored if the user does not tap in the general area of the target
(correct area is the size of the target icon)
Count down timer; calibration will be ignored when time runs out
Figure 5– LCD touch screen calibration screen target one
Tap on the center of the second target (bottom right area of the screen) to complete the calibration:
If the user does not tap in the general area of the first target, then calibration will not be saved no matter what happens in the
second target
Count down timer; calibration will be ignored when time runs out
Tap on the center of the second target and calibration will be saved
automatically

NOTE: Both the targets must be tapped correctly for the calibration to take effect. This is done to prevent the calibration from changing dramatically from the default.
