Displaying Status Messages
Under normal conditions, set the LCD to display status messages, including:
 iSTAR boot information
 Date and time
 Firmware version
 Controller status information.
Messages typically display for approximately four seconds, separated by an interval of about
one second. In some instances, however, a message can display until it is cancelled or
terminated.
Setting LCD Status Message Display
You can display LCD general status messages for a controller by setting the SW3 rotary switch
to positions 0 (zero) or F. Setting the SW3 switch to 0 or F also controls the ICU Block feature,
preventing or allowing users from modifying the ICU configuration, as shown in Table 10-2.
 When ICU Block is On (set SW3 to F) – the LCD displays general status messages;
however, fields in the ICU dialog box are unavailable and cannot be edited.
 With ICU Block Off (set SW3 to 0) – the LCD displays general status messages, and users
can read, write, and update the ICU configuration.
