Fault Action
Frequency Output Fault Action
controls the behavior of the Frequency 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.
