8 Rosemount 405 Compact Reference Manual CONSIDERATIONS Functional The Rosemount 405 produces the most accurate and repeatable measurement when it is used in single-phase flow or steam flow above the saturation temperature. Location of the 405 in pulsating flow will cause a noisy signal. Vibration can also distort the output signal and compromise the structural limits of the flowmeter. Mount the 405 in a secure run of pipe as far as possible from pulsation sources such as check valves, reciprocating compressors or pumps, and control valves. Install the 405 in the correct location within the piping branch to prevent measurement inaccuracies caused by flow disturbances. Maximum temperature for direct mount applications is 450 F (232 C). Maximum temperature for remote mount applications is 850 F (454 C). 1-2

28 Rosemount 405 Compact Reference Manual TROUBLESHOOTING If a malfunction is suspected despite the absence of a diagnostic messages on the communicator display, follow the procedures described below to verify that the flowmeter hardware and process connections are in good working order. Always approach the most likely and easiest-to-check conditions first. Symptom Possible Cause Corrective Action Questionable accuracy or erroneous flow signal Improper installation System leaks Contamination/plugging Closed valve Calibration Connections (remote mount only) Entrapped air (liquid applications) 3095MFC misalignment Operating conditions Is the flow arrow pointed in the direction of the flow? Verify that the cross reservoirs are perfectly level with one another. Is there sufficient straight run upstream and downstream of the flowmeter? Check for leaks in instrument piping. Repair and seal all leaks. Remove the flowmeter and check for contamination. Verify that both 3095MFC (PH & PL) or (MH & ML) valves are open. Verify that vent, equalizer, and line valves are properly positioned per the start up procedure. Is the calibration too high or low for the flow rate? Verify that the high side of the electronics is connected to the high side of the flowmeter. Check the same for the low side. Are there uneven water legs caused by air entrapment in the instrument connections? If so, bleed air. Misalignment of the flowmeter beyond 3 degrees will cause an erroneous signal. Are the operating conditions in compliance with those given at the time the flowmeter was purchased? Check the flow calculation and the fluid parameters for accuracy. Double-check pipe inside diameter for proper sizing. Spiking flow signal Two-phase flow The flowmeter is a head measurement device and will not accurately measure a two-phase flow. Spiking flow signal (Stream Service) Milliamp reading is zero Electronics not in communication Milliamp reading is low or high No response to changes in applied flow Low reading/high reading Erratic reading for pressure variable Improper insulation (Vertical pipes only) Excessive vibration Added insulation may be required to ensure that a phase change occurs at the cross reservoirs. Check the impulse piping for vibration. Check if power polarity is reversed Verify voltage across terminals (should be 10 55V dc) Check for bad diode in terminal block Replace electronics terminal block Check power supply voltage at electronics (10.5V minimum) Check load resistance (250 ohms minimum) Check if unit is addressed properly Replace electronics board Check pressure variable reading for saturation Check if output is in alarm condition Perform 4 20 ma output trim Replace electronics board Check test equipment Check impulse piping for blockage Check for disabled span adjustment Check electronics security switch Verify calibration settings (4 and 20 ma points) Contact factory for replacement Check impulse piping for blockage Check test equipment Perform full sensor trim (if software revision is 35 or higher) Contact factory for replacement Check impulse piping for blockage Check damping Check for EMF interference Contact factory for replacement 4-2

29 Reference Manual Rosemount 405 Compact Check Flow Direction Check that the flow arrow on the neck of the 405 points in the direction of flow. If the DP transmitter is remote mounted from the 405, be sure that the impulse tubing is connected correctly from the 405 to the DP transmitter (high to high and low to low). Check Orientation Improper orientation can result in inaccurate measurements. Check Zero The transmitter may read off in the high or low direction if not zeroed properly at start-up/commissioning. Refer to the appropriate transmitter reference manual for additional information. Check Valves The correct valve setting for flow measurement are; equalizer valve fully closed, high and low side valves fully open. Check Configuration/Scaling Is the 20mA DP URL of the 405 set properly? This may involve sizing the 405 in the Toolkit Software program to confirm. Confirm the DCS or PLC and transmitter on 405 are scaled consistently. Is the square root being taken in the DCS or transmitter attached to the 405? The square root should not be taken in both places. Check 3095MV Configuration If a Rosemount 3095MV transmitter is being used, its enhanced functionality should be taken into account during configuration and troubleshooting. The square root should not be taken in the DCS if a 3095MV transmitter is being used. See the Rosemount 3095MV reference manual (document number ) for additional information. 4-3

30 Rosemount 405 Compact Reference Manual RTD MAINTENANCE Remote Mount This section covers RTD maintenance procedures. If an RTD needs to be replaced on a remote mount, proceed as follows: 1. Close instrument valves to ensure that the pressure is disconnected from the transmitter. 2. Open the bleed valves on the transmitter to remove all pressure. 3. Remove the cap. 4. Remove the RTD wiring only from the terminal. 5. Remove the Terminal Housing from the head. 6. Pull the RTD wire out of the nipple and remove the RTD. The RTD is in a thermowell, so no live line pressure will be present. 7. Install the new RTD and thread the wires through the nipple. 8. Using the appropriate thread lubricant or tape, install the terminal housing onto the remote head. 9. Reconnect the RTD wires to the terminal. This diagram is for a typical RTD transmitter wiring connection. 10.Open the instrument valves.
