Unlock device to makechanges to the device.Analog Channel 1 Saturated / WarningThe primary variable is outside the analog output range.1. Check the primary value.2. Check the analog output scaling.Analog Channel 2 Saturated / WarningThe secondary variable is outside the analog output range.1. Check the secondary value.2. Check the analog output scaling.Analog Channel 1 Fixed / ModeOutput 1 is either being tested, calibrated, or accidentally left on hold. Afault 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 1out of hold mode.Analog Channel 2 Fixed / ModeOutput 2 is either being tested, calibrated, or accidentally left on hold. Afault 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 2out of hold mode.4 – More Status Available4 – More Status Available4 – More Status Available4 – More Status Available4 – More Status AvailableTemperature Status BitsByte / Bit Meaning / Class Device Status Bits Set0 / 02 / 02 / 12 / 25 / 1Temperature Error / ErrorThe temperature measuring circuit is open or shorted. Check the wiring andthe temperature element in the sensor. If the temperature element in thesensor is open or shorted, replace the sensor.Temperature High / WarningThe measured temperature is above the temperature range of the transmitterand can damage the sensor. The temperature limits are:1066P / 1066DO, CL, and OZ: Temperature > 150°C1066C and 1066T: Temperature > 300°C1. Check process temperature.2. Check sensor and its wiring.Temperature Low / WarningThe measured temperature is below the temperature range of the transmitterand can damage the sensor. The temperature limits are:1066P / 1066DO, CL, and OZ: Temperature < -15°C1066C and 1066T: Temperature -25°C1. Check process temperature.2. Check sensor and its wiring.RTD Sense Line Open / WarningThe 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 wirejumper to connect sense and return terminals.Temperature Calibration In Progress / OtherA temperature calibration is or has been performed.4 – More Status Available7 – Field Device Malfunction1 – Non-primary Variable outof Limits4 – More Status Available1 – Non-primary Variable outof Limits4 – More Status Available4 – More Status Available4 – More Status Available108 HART Communications
