Sleep Time
The display sleep time determines whether the LCD in the display module should go blank
or not after a period of time when no user activity occurs with the device. The display sleep
time can be set to one of the following settings:
• Never (don't ever go to sleep)
• 5 seconds
• 10 seconds
• 30 seconds
• 1 minute
• 5 minutes
• 1 hour
Sleep time setup is accessed from the Display Setup Menu (see Fig. 56). The current
parameter setting is displayed when the page is initially entered.

The up and down arrow buttons are used to scroll through the time choices on the edit
line. The right and left arrow buttons are used to tab to the save commands, "Yes" and
"No". When the input focus is on the save commands the up and down arrow buttons scroll
between "Yes" and "No". When the time is set to the value desired the "Yes" command is
selected and the OK button is pressed to commit the change. If the user decides not to save
the displayed time, the "No" command is selected and the OK button is pressed. In both
save command cases control returns back to the Display setup menu.
Inactivity Time
The display inactivity time determines whether any non-status (configuration, etc.) page
should be automatically exited after a period of time of no user activity on the display
module (no button presses). If this parameter is enabled, any page other than the Home,
Lockout, and diagnostics pages are automatically exited if the page is idle for the time
specified by this parameter. The intent of this parameter is to not leave the display on
a configuration page after the user has left the display module vicinity to prevent any
unauthorized changes to a parameter setting. The following settings can be selected for
this parameter:
• None (do not automatically exit any page)
• 30 seconds
• 1 minute
• 5 minutes
• 30 minutes
• 1 hour
Inactivity time setup is accessed from the Display Setup Menu (see Fig. 57). The current
parameter setting is displayed when the page is initially entered.
