Power Up

The Power up chart shows the respective TD7 screens during a power up of the main processor.
This process takes from 30 to 50 seconds depending on the number of installed Options. On all
power ups, the software model will always transition through the 'Stopped' Software state in-
dependent 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.
