Power Down Mode

    In Power Down Mode, the C Series Functional Safety powers off and ceases all operation. The User Program stops running, all outputs de-energize, and the module no longer communicates with LabVIEW.

    Automatic self-diagnostics can trigger Power Down Mode in the following situations:

    • Short condition on both DO FETs on a single output channel
    • Overvoltage on Vsup
    • Internal overvoltage faults

    If the module goes into Power Down Mode, follow these steps:

    1. Inspect all inputs and outputs to verify they are within specifications.
    2. Cycle external Vsup to the module.
    3. Contact NI if the module goes into Power Down Mode a second time.
