10 / 0
analog Channel 1 Saturated / Warning
The primary variable is outside the analog output range.
1. Check the primary value.
2. Check the analog output scaling.

10 / 1
analog Channel 2 Saturated / Warning
The secondary variable is outside the analog output range.
1. Check the secondary value.
2. Check the analog output scaling.

13 / 0
analog Channel 1 Fixed / Mode
Output 1 is either being tested, calibrated, or accidentally left on hold. A fault
condition could also set the analog output to a fixed value.
If there is no active fault, wait for test or calibration to end or take Output 1
out of hold mode.
4 – More Status available
13 / 1
analog Channel 2 Fixed / Mode
Output 2 is either being tested, calibrated, or accidentally left on hold. A fault
condition could also set the analog output to a fixed value.
If there is no active fault, wait for test or calibration to end or take Output 2
out of hold mode.

Temperature Error / Error
The temperature measuring circuit is open or shorted. Check the wiring and
the temperature element in the sensor. If the temperature element in the sen-
sor is open or shorted, replace the sensor.

7 – Field Device Malfunction
2 / 0
Temperature high / Warning
The measured temperature is above the temperature range of the transmitter
and can damage the sensor. The temperature limits are:
1066P / 1066DO, CL, and OZ: Temperature > 150 °C
1066C and 1066T: Temperature > 300 °C
1. Check process temperature.
2. Check sensor and its wiring.
1 – Non-primary variable out
of limits
4 – More Status available
2 / 1
Temperature low / Warning
The measured temperature is below the temperature range of the transmitter
and can damage the sensor. The temperature limits are:
1066P / 1066DO, CL, and OZ: Temperature < -15 °C
1066C and 1066T: Temperature -25 °C
1. Check process temperature.
2. Check sensor and its wiring.
1 – Non-primary variable out
of limits
4 – More Status available
2 / 2
RTD Sense line Open / Warning
The sense line of the temperature sensor is not connected.
1. Check sensor wiring.
2. If a 2-wire RTD is being used for temperature compensation, use wire
jumper to connect sense and return terminals.

5 / 1
Temperature Calibration In progress / Other
A temperature calibration is or has been performed.
