All Power-Fail, RAM, ROM, Database Integrity, and other self-test failure errors can initiate a restart of the card. During a restart, the outputs are off (zero current) while all the self-tests are performed. After the card successfully completes all the powerup self-tests, the outputs are driven to 1 mA and wait for the system to download the configuration and enable the channels. The download and channel enabling are performed automatically.
Analog output card outputs cannot be driven below 1 mA except when in an error condition.
