Fig. 29. Login required
If the user is authorized to change configuration settings, knows the display password,
and wishes to continue with the parameter change, the user presses the OK button with
the input focus on the "Yes" selection. If the user isn't authorized to change the parameter
or doesn't want to change it, the user tabs to the "No" selection with the right arrow or left
arrow button and presses the OK button. Control returns back to the previous page if the
user elects to not make the parameter change. If the user elects to change the parameter
setting, the user is asked to login (see Fig. 30).

The 3-digit display password is entered by scrolling the digits and tabbing to the "Yes"
command and pressing the OK button to login. A successful login transitions to the
configuration page. An unsuccessful login (wrong password) displays an "INVALID
PASSWORD" message (see Fig. 31). If the user elects to cancel the login, tabbing to the
"No" command and pressing the OK button returns control to the previous page.
Fig. 31. Invalid login
A successful login is active for all pages navigated to while staying within the configuration
pages. When the display module returns back to the Home or Lockout page the login status
is negated and future parameter changes will require the user to login again.
Navigating to these display setup functions starts from the "Display menu" selection on the
Home page (see Fig. 32). The Display Menu page allows the user to scroll to the function
desired.
