HART Processor Detects an Error
During startup, the main processor sets a timeout (200 ms) and a DAC value for the
HART processor to use if it ever stops receiving communications. Once the HART
processor detects this timeout, the DAC value is used. The DAC value is determined by
the configuration of the channel Fault Mode setting.
Main CPU Failure
In the case where the main CPU does not run on power up, the outputs remain disabled.
The HART Processor does not boot up until specifically commanded via special
bootloader commands.
Disabled Channels
A disabled channel is held in reset and no processing takes place for that channel.
Technical Assistance
Note that your module contains electrostatic components that are susceptible to damage
from electrostatic discharge (ESD). An electrostatic charge can accumulate on the surface
of ordinary wrapping or cushioning material. In the unlikely event that the module
should need to be returned to Spectrum Controls Inc., please ensure that the unit is
enclosed in approved ESD packaging (such as static-shielding/metallized bag or
black conductive container). Spectrum Controls, Inc. reserves the right to void the
warranty on any unit that is improperly packaged for shipment.
For further information or assistance, please contact your local distributor, or call the
