Using Trim Pots and the Data Access Tool (DAT) 5-9
Error Conditions
When the DAT detects an error in its own operation, it displays the error screen.
The error screen consists of “Err” and a two-digit error code, as shown below.
The DAT can experience two different types of errors, internal errors and
communication errors.
Internal DAT Errors
Internal DAT errors are non-recoverable. When the DAT experiences an internal
error, it displays the error screen, and does not respond to any key presses. Remove
and re-install the DAT. If this does not clear the error, the DAT must be replaced.
Communication Errors
The DAT continually monitors the interface between the DAT and the controller
to ensure a good communication path. If the DAT loses communication with the
controller for more than three seconds, it generates an interface time-out error. The
DAT automatically attempts to re-establish communications. The error screen
displays until the DAT regains communications with the processor. All key presses
are ignored until the display clears.

power to the controller.
