Troubleshooting
April 2019
Cause
The pickoff amplitude is too low.
Recommended actions
1. Check the drive gain and the pickoff voltage.
2. Check the wiring between the sensor and the transmitter.
3. Check the sensor coils for electrical shorts. If you find problems, replace the sensor. Refer to
internal electrical
4. Check the integrity of the sensor tubes.
5. Ensure that the sensor is completely full or completely empty.
6. Replace the sensor.
7. Contact customer service.
15.2.3 [004] Temperature Sensor Out of Range
Alert
Sensor Failed
Cause
The value computed for the resistance of the line RTD is outside limits.
Recommended actions
1. Check the wiring between the sensor and the transmitter. Refer to
2. Verify that the process temperature is within range of the sensor and the transmitter.
3. Check the sensor coils for electrical shorts. If you find problems, replace the sensor. Refer to
internal electrical
4. Check the feedthrough pins. Contact customer service for assistance. If you find problems, replace the
sensor.
5. Contact customer service.
15.2.4 [005] Mass Flow Rate Overrange
Alert
Extreme Primary Purpose Variable
Cause
The measured flow is outside the sensor's flow limits.
Recommended actions
1. Check your process conditions against the values reported by the device.
2. Verify that the transmitter is configured correctly for the connected sensor.
3. Check for two-phase flow.
Refer to Check for two-phase flow (slug
