Table 4-3:Raven Status Indications

Notes:

Without latch mode:

The status indications are reset when the fault disappears.

With latch mode:

The Short and Over Temperature Failure status indications are reset when the enable signal is temporarily removed from the enable input.

Multiple faults:

Only the reading of the first fault is reliable. Additional faults add on to the status outputs and the indication is therefore meaningless.
