Page 19: Chapter 2. Error Codes
Chapter 2. Error Codes Chapter 2. Error Codes Introduction The XGF868i ultrasonic flow transmitter is a reliable, easy to maintain instrument. When properly installed and operated, as described in the Startup Guide, the meter provides accurate flow rate measurements with minimal user intervention. - Page 20 Chapter 2. Error Codes E0: No Error Problem: No error condition currently exists. Cause: This message appears briefly to confirm that the response to another error message has corrected the problem. Action: No action is required. E1: Low Signal Problem: Poor ultrasonic signal strength or the signal exceeds the limits entered via the Keypad Program.
- Page 21 Chapter 2. Error Codes E4: Signal Quality Problem: The signal quality is outside the limits programmed in the Channelx-Set up-Signal submenu of the Keypad Program. Cause: The peak of the upstream or downstream correlation signals has fallen below the correlation peak limit, as set in the Channelx-Set up-Signal submenu.
- Page 22 Chapter 2. Error Codes E8: Temperature In Problem: This message indicates a temperature input error. Cause: The temperature exceeds the specified limits for the analog/RTD inputs option card or no input device is connected. Action: Check the temperature transmitter and the connecting cable. Refer to Chapter 1, Calibration, and recalibrate the analog/RTD inputs option card.
- Page 23 Chapter 2. Error Codes E13: Over Range Problem: This error code message indicates that the present measurement exceeds the range of the meter. Cause: A internal mathematical overflow has occurred in either the volumetric or mass flow calculations. Action: Select larger measurement units or a shorter time interval for the current measurement parameter. For example, choose KSCF/M instead of SCF/M in the Channelx-System menu.
