Recommended action
1. Restart the transmitter.
2. If condition persists, replace the transmitter. Contact
the nearest Emerson Process Management Field
Service Center if necessary.
1. Verify the sensor connection and wiring. Refer to the
wiring diagrams found on the transmitter label to
ensure proper wiring.
2. Verify the integrity of the sensor and sensor lead
wires. If the sensor is faulty, repair or replace the
sensor.
1. Verify the process temperature is within the specified
sensor's range. Use the Sensor Information button to
compare with the process temperature.
2. Verify the sensor is properly wired and connected to
the terminals.
3. Verify the integrity of the sensor and sensor lead
wires. If the sensor is faulty, repair or replace the
sensor.
1. Verify the ambient temperature is within the device
specified operating range using the Terminal
Temperature Information Button.
1. Verify sensor type and number of wires matched the
Sensor Configuration of the device.
2. Reset the device.
3. If error persists, download the transmitter
configuration.
4. If error still present, replace the transmitter.
1. Perform a processor reset.
2. View other alerts to see if the transmitter indicates a
specific problem.
3. If the condition persists, replace the device.
