Check mA Output Fault Action
mA Output Fault Action controls the behavior of the mA Output if the transmitter
encounters an internal fault condition. If the mA Output is reporting a constant value
below 4 mA or above 20 mA, the transmitter may be in a fault condition.
1.
Check the status alerts for active fault conditions.
2.
If there are active fault conditions, the transmitter is performing correctly. If you
want to change its behavior, consider the following options:
•
Change the setting of mA Output Fault Action.
•
For the relevant status alerts, change the setting of Alert Severity to
Ignore
.
Restriction
For some status alerts, Alert Severity is not configurable.
3.
If there are no active fault conditions, continue troubleshooting.
12.21
Check for radio frequency interference (RFI)
The transmitter's Frequency Output or Discrete Output can be affected by radio frequency
interference (RFI). Possible sources of RFI include a source of radio emissions, or a large
transformer, pump, or motor that can generate a strong electromagnetic field. Several
methods to reduce RFI are available. Use one or more of the following suggestions, as
appropriate to your installation.
Procedure
•
Use shielded cable between the output and the receiving device.
-
Terminate the shielding at the receiving device. If this is impossible, terminate
the shielding at the cable gland or conduit fitting.
-
Do not terminate the shielding inside the wiring compartment.
-
360-degree termination of shielding is unnecessary.
•
Eliminate the RFI source.
•
Move the transmitter.
12.22
Check Frequency Output Mode
If the transmitter is configured for two frequency outputs, and Frequency Output Mode is
not configured correctly for your application, the frequency outputs may exhibit
unexpected behavior.
Frequency Output Mode is used only to define the relationship between two frequency
outputs. If your transmitter is not configured for two frequency outputs, Frequency
Output Mode is not causing your output problem.
