Chapter 2: Screen Types
Log Screens
Log screens are used to view recorded system information. The width and length of the
log screens may be wider and longer than allowed by the LCD display area. The arrow
and page keys can then be used to view the entire log. All systems are configured with the
following logs: Operation Log, Trend Log, Alarm Log, Failure Log, and User Log. Other
log types may also be included, depending on system options. Below is an example of a
log screen.
