Power Up Diagram
The following diagram shows the respective TD7
AdaptiView™ screens during a power up of the UC800
and display. This process takes 25 seconds for the
UC800 and 90 seconds for the display. On all power
ups, the software model always will transition through
the 'Stopped' Software state independent of the last
mode. If the last mode before power down was 'Auto',
the transition from 'Stopped' to 'Starting' occurs, but it
is not apparent to the user.
