c) Perform RTD resistance checks and check for shorts to case. If you find problems, replace the
sensor.
d) Check the continuity of all wires from the transmitter to the sensor.
2. Check your process conditions against the values reported by the device.
3. Check the feedthrough pins. Contact customer service for assistance. If you find problems, replace the
sensor.
4. Check the core processor housing for moisture, corrosion, or verdigris.
5. Contact customer service.
15.2.14 [017] Sensor Case Temperature (RTD) Failure
Alert
Sensor Failed
Cause
The values computed for the resistance of the meter and case RTDs are outside limits.
Recommended actions
1. Check the wiring between the sensor and the transmitter.
a) Refer to the installation manual and ensure that the wiring has been performed according to
instructions. Obey all applicable safety messages.
b) Verify that the wires are making good contact with the terminals.
c) Perform RTD resistance checks and check for shorts to case. If you find problems, replace the
sensor.
d) Check the continuity of all wires from the transmitter to the sensor.
2. Check your process conditions against the values reported by the device.
3. Contact customer service.
