Fault Action
mA Output Fault Action controls the behavior of the mA 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.
Procedure
1. Set mA Output Fault Action as desired.
• Default: Downscale
Important
If you set mA Output Fault Action to None, the mA Output will be controlled by the setting of Process
Variable Fault Action. In most cases, if you set mA Output Fault Action to None, you should also set
Process Variable Fault Action to None.
2. If you set mA Output Fault Action to Upscale or Downscale, set mA Output Fault Level to the signal
that the mA Output will produce during a fault.

8.3 Configure the Frequency Output

The Frequency Output is used to report current values of process variables. The frequency varies between
0 Hz and 14500 Hz in proportion to the current value of the assigned process variable.
Depending on your purchase order and channel configuration, your transmitter may have zero or one
Frequency Output. One channels is available to use as a Frequency Output:
• Only Channel B can be configured as either Frequency Output 1 or Discrete Output 1.
