What to do if Rosemount Measuring Instruments show 'Sensor Hi Limit Exceeded'?
If the Rosemount Measuring Instruments display 'Sensor Hi Limit Exceeded', it could be due to the flow rate being greater than 43 ft/sec. Try lowering the flow velocity or increasing the pipe diameter. Another possible cause is improper wiring. In this case, you should check the coil drive wiring and sensor coils and perform sensor test A - Sensor Coil.
What to do if Rosemount Measuring Instruments detect 'Reverse Flow'?
If the Rosemount Measuring Instruments detect 'Reverse Flow', first verify the wiring between the sensor and transmitter, as the electrode or coil wires might be reversed. If the wiring is correct, check if the flow is indeed reversed; if it is, turn ON Reverse Flow Enable to read the flow. Finally, ensure the sensor is installed correctly; if not, reinstall it or switch either the electrode wires (18 and 19) or the coil wires (1 and 2).
What to do if Rosemount Measuring Instruments show 'Empty Pipe Detected'?
If your Rosemount Measuring Instruments display 'Empty Pipe Detected', here are a few things to check: * If the pipe is actually empty, the message will clear when the pipe is full. * Verify the wiring matches the appropriate wiring diagrams. * Perform sensor tests C and D. * Ensure the conductivity is greater than or equal to 5 microsiemens per cm. * Adjust tuning of Empty Pipe parameters.
What to do if Rosemount Measuring Instruments experience 'Universal Trim Failure'?
If the Rosemount Measuring Instruments experience a 'Universal Trim Failure', consider the following: 1. Ensure a known flow is established in the sensor before performing Universal Auto-Trim calibration. 2. Verify that the wiring matches the appropriate wiring diagrams. 3. Maintain a constant flow in the sensor during the Universal Auto-Trim routine. 4. Confirm the flow rate through the sensor matches the value entered during the Universal Auto-Trim routine. 5. Replace the sensor calibration number with 1000005010000001 if the incorrect calibration number was entered. 6. Correct the sensor size setting. 7. Perform sensor tests C and D.
What to do if Rosemount Measuring Instruments have 'Coil Drive Open Circuit'?
If the Rosemount Measuring Instruments indicate a 'Coil Drive Open Circuit', first check the coil drive wiring and sensor coils, and perform sensor test A - Sensor Coil. If you are using another manufacturer’s sensor, change the coil current to 75 mA and perform a Universal Auto Trim to select the proper coil current. If the issue persists, it could be a Circuit Board Failure, in which case you should replace the Rosemount 8732 Electronics. If it is a Coil Circuit OPEN Fuse, return the device to the factory for fuse replacement.
What to do if Rosemount Measuring Instruments show 'Auto Zero Failure'?
If Rosemount Measuring Instruments display 'Auto Zero Failure' (after cycling power without making changes), ensure the flow is set to zero and then perform autozero. Also, replace any unshielded cable with shielded cable. Check for moisture problems. Finally, ensure the sensor is filled with process fluid, as an empty pipe can cause this issue.
What to do if Rosemount Measuring Instruments display 'Electronics Temperature Out of Range'?
If the Rosemount Measuring Instruments show 'Electronics Temperature Out of Range', it means the ambient temperature has exceeded the electronics temperature limits. Move the transmitter to a location with an ambient temperature range of -40 to 165 °F (-40 to 74 °C).
What to do if Rosemount Measuring Instruments experience 'Electronics Failure'?
If the Rosemount Measuring Instruments experience an 'Electronics Failure' due to an electronics self-check failure, replace the electronics.
