3. OPERATION 3. OPERATION IMPORTANT Do not turn off the power to the transmitter immediately after setting the data using the BT200. If the transmitter is turned off less than 30 seconds after parameters have been set, the setting data will not be stored in the transmitter. • Damping time constant setting See Page 3-6 Setting the response time of the transmitter smooths the output with rapid changes in input. The damping time constant can be set between 1 and 99 seconds.
3. OPERATION • Sensor Backup Function (YTA320 only) See Page 3-10 Configure the transmitter to automatically transfer the input from Sensor1 to Sensor2 when Sensor1 fails. H20: SNSR BACKUP, H21: RETURN SNS1 • Copy the Setting Data to the BT200 See Page 3-11 Copy the setting data of one temperature transmitter to another via the BT200.

3. OPERATION USER CAL IGNORE : Ignore user trim value and return to the factory set value. USER CAL ACT : Use user trim value. NOTE Regardless of restarting the transmitter, the “USER CAL ACT” is always set and the user trim value is used as the input signal unless it is cleared by “USER CAL CLEAR.” 3.2.16 CJC Selection For thermocouple input, terminal temperature measured by an internal sensor is used for Cold Junction Compensation function.
4. SELF-DIAGNOSTICS 4. SELF-DIAGNOSTICS The temperature transmitter continually monitors its own performance during normal operation. If an error occurs, it displays and records the error to the logging parameters, and with the integral indicator, an error code corresponding to the error is displayed. 4.1 Error Message An error message is displayed on the BT200 when there is a problem with functions. The error message can be checked with the parameter number of each item ■60:SELF CHECK.
4. SELF-DIAGNOSTICS Table 4.1 List of Error Codes Indicator BT200 display Cause Output operation upon error Action N/A GOOD Er-01 Output Too Low Input value is lower than the PV low range value. Outputs goes to minimum value. (3.68 mA, –2.0%) Check the LRV and adjust. Er-02 Output Too High Input value is higher than the PV Upper range value. Outputs goes maximum value. (20.8 mA, 105%) Check the URV and adjust. Er-03 Sensor1 Failure Sensor1 fails or disconnects from the terminal box.
4. SELF-DIAGNOSTICS 4.2 Warning ● Example: Displaying “Setting” and “Special” warning 1. Set “3FFC0108” in the Data to set column for F combination in the table above. SET H50:WARNING ENBL 00000000 3FFC0108 1) Warning and contents The YTA series has a warning display function. DEL The warning display function displays a warning when there is an incorrect use status such that a setting is out of the specified range.
4. SELF-DIAGNOSTICS Table 4.2 List of warnings Class Setting Parameter Status Countermeasure LRV Too Low The LRV setting is lower than the temperature range (GS stated value). Check the LRV setting. LRV Too High The LRV setting is higher than the temperature range (GS stated value). Check the LRV setting. URV Too Low The URV setting is lower than the temperature range (GS stated value). Check the LRV setting.
4. SELF-DIAGNOSTICS 4.3 Logging Function The YTA series has the capability to store useful information for trouble shooting. The % value is calculated from the number of BCC errors that occurred in BRAIN communication reception frame and the number of transmissions/receptions. Turning the power off clears the data. 4.3.1 Error Log *1 Up to four error histories are stored in the transmitter memory. The transmitter records an error that continues to occur for more than 6 minutes.
