Troubleshooting
Symptom Corrective Action
Impulse piping
• Check for entrapped gas in liquid lines or for liquid in gas lines.
• Make sure that process fluid has not frozen within the process flange.
• Ensure that block valves are fully open and equalize valves are fully and tightly closed.
Sensore module
• The sensor module is not field repairable and must be replaced if found to be defective. Check for obvious
defects, such as a punctured isolating diaphragm or fill fluid loss, and contact your nearest Emerson Process
Management Service Center.
Low PV Reading or No
PV Reading
Primary element
• Check the installation and condition of the primary element.
• Note any changes in process fluid properties that may affect output.
Loop wiring
• Check for adequate voltage to the transmitter. It should be 12 to 42.4 V dc for HART with no load at the
transmitter terminals.
• Check the milliamp rating of the power supply against the total current being drawn for all transmitters
being powered.
• Check for shorts and multiple grounds.
• Check for proper polarity at the signal terminal.
• Check loop impedance.
• Check the wire insulation to detect possible shorts to ground.
Impulse piping
• Check to ensure that the pressure connection is correct.
• Check for leaks or blockage.
• Check to ensure that blocking valves are fully open and that bypass valves are tightly closed.
• Check for entrapped gas in liquid lines or for liquid in gas lines.
• Check for sediment in the transmitter process flange.
• Make sure that process fluid has not frozen within the process flange.
Feature board electronics
• Check the sensor limits to ensure calibration adjustments are within the sensor range and that calibration is
correct for the pressure being applied.
• Confirm that the electronics housing is properly sealed against moisture.
• If the feature board electronics are still not functioning properly, substitute new feature board electronics.
Flow configuration (fully compensated mass and energy flow feature board only)
• Verify flow configuration is correct for current application
Process temperature RTD input
• Verify all wire terminations
• Verify sensor is a Pt 100 RTD
• Replace Pt 100 sensor
Sensor module
The sensor module is not field repairable and must be replaced if found to be defective. Check for
obvious defects, such as a punctured isolating diaphragm or fill fluid loss, and contact your nearest
Emerson Process Management Service Center.
Sluggish Output
Response/Drift
Primary element
• Check for restrictions at the primary element.
Impulse piping
• Check for leaks or blockage.
• Ensure that blocking valves are fully open
• Check for sediment in the transmitter process flange.
• Check for entrapped gas in liquid lines and for liquid in gas lines.
• Ensure that the density of fluid in impulse lines is unchanged.
• Make sure that process fluid has not frozen within the process flange.
Feature board electronics
• Confirm that damping is correctly set.
• Confirm that the electronics housing is properly sealed against moisture.
Sensor module
• The sensor module is not field repairable and must be replaced if found to be defective. Check for obvious
defects, such as a punctured isolating diaphragm or fill fluid loss, and contact your nearest Emerson Process
Management Service Center.
• Confirm that the electronics housing is properly sealed against moisture.
