Discrete Output Fault Action controls the behavior of a Discrete Output if the transmitter detects a fault
condition.
Important
• The fault action is implemented only if Alert Severity is set to Failure. If Alert Severity is set to any other
option, the fault action is not implemented.
For some faults only: If Fault Timeout is set to a non-zero value, the transmitter will not implement the
•
fault action until the timeout has elapsed.
CAUTION
Do not use Discrete Output Source as a fault indicator. If you do, you may not be able to distinguish a fault
condition from a normal operating condition. If you want to use the Discrete Output as a fault indicator,
see Fault indication with a Discrete
Procedure
