Factory default programming associates specific relay functions with the top
eight pushbuttons and LEDs, as listed in Table 7.13. For a concise listing of
the default programming for the front-panel pushbuttons and LEDs, see Front-

operator control pushbuttons to be programmed to display a particular HMI
screen category. The HMI screen categories available are Alarm Points,
