Troubleshooting of Comet T0110 Temperature Transmitter

Device Error States

The device continuously monitors its status during operation. If an error is detected, the LCD shows the corresponding error code:

Error 0
The first line displays “Err0.” This indicates a checksum error in the stored settings within the device’s memory. The output value is less than 3.8 mA. This error occurs if there was an incorrect writing procedure to the device’s memory or if the calibration data is damaged. In this state, the device does not measure or calculate values. This is a critical error; please contact the instrument distributor for assistance.

Error 1
The LCD displays “Err1.” The output value is approximately 24.5 mA. This error signifies that the measured value exceeds the upper limit of the allowed full-scale range. It occurs when the measured temperature is higher than about 600°C (indicating a high, non-measurable resistance in the temperature sensor, possibly due to an open circuit).

Error 2
The LCD shows “Err2.” The output value is around 3.8 mA. This condition indicates that the measured value is below the lower limit of the allowed full-scale range. It happens when the measured temperature is lower than approximately -210°C (suggesting low resistance in the temperature sensor, potentially caused by a short circuit).

Error 3
The LCD displays “Err3” on the upper line. This error indicates a problem with the internal A/D converter (the converter is unresponsive, which may indicate damage). No measurements can be taken in this state, and the output value is about 3.8 mA. This is a serious issue; please contact the instrument distributor for resolution.
