Installation Instructions
Rosemount 3051CD + 5-Valve Manifold Installation Guide
1. Pre-Installation Preparation
Tools and Materials Required:
Rosemount 3051CD pressure transmitter
5-valve manifold assembly (block and bleed type)
Wrenches (appropriate sizes for manifold and process connections)
Torque wrench Calibration equipment (HART communicator or AMS Trex device)
Safety gloves and goggles Leak detection solution or soapy water
Safety Precautions:Ensure the process is depressurized and isolated before installation.
Verify compatibility of the manifold material with the process fluid.
Follow site-specific safety protocols (e.g., hot work permits, lockout/tagout).
2. Mounting the 5-Valve Manifold
Step 1: Inspect the ManifoldConfirm the manifold is clean and free of debris.
Check valve markings (HIGH, LOW, and BLOCK/VENT ports) for correct orientation.
Step 2: Install Manifold to Process ConnectionsApply thread sealant to the male threads of the process connections (e.g., NPT, BSP).
Hand-tighten the manifold onto the process piping. Use two wrenches to avoid twisting the assembly.
Torque the connections to the manufacturer's specification (typically 15-20 ft-lb for ½" NPT).
Step 3: Verify AlignmentEnsure the manifold is oriented for easy access to valves and transmitter.
Avoid stress on the manifold due to misaligned piping.
3. Installing the Rosemount 3051CD Transmitter
Step 1: Mount the TransmitterAttach the transmitter to the manifold using the mounting nuts or bolts.
Hand-tighten initially, then torque to 15-20 ft-lb (refer to datasheet).
Step 2: Connect Impulse Lines (if applicable)For remote diaphragm seals, connect impulse lines to the HIGH and LOW ports.
Ensure impulse lines are sloped to prevent gas entrapment (gas applications) or sediment buildup (liquid applications).
4. Electrical Connections
Step 1: Wire the TransmitterRemove the transmitter's electronics housing cover.
Connect the power supply wires to the terminal block (Terminals + and -).
Use shielded twisted-pair cable for noise immunity.
Step 2: Check PolarityConfirm correct polarity (+ to +, - to -) to avoid damaging the transmitter.
Step 3: Secure Conduit ConnectionsInstall conduit fittings to meet IP66/NEMA 4X requirements.
Apply thread sealant to conduit entries.
5. Manifold Valve Configuration
Valve Positions During Installation:Isolate Process:Close the HIGH and LOW block valves (valves 1 and 2).
Open Equalizing Valve:Ensure valve 3 (equalizing valve) is closed initially.
Close Bleed Valves:Keep valves 4 and 5 (bleed/vent valves) closed.
Procedure for Start-Up:Open the HIGH and LOW block valves (valves 1 and 2).
Slowly open the equalizing valve (valve 3) to balance pressure across the transmitter.
Use bleed valves (4 and 5) to vent trapped air or fluid during calibration.
6. Calibration and Configuration
Step 1: Zero CalibrationWith no pressure applied, use a HART communicator to navigate:
Device Setup > Calibration > Sensor Trim > Zero Trim.Follow on-screen prompts to complete the trim.
Step 2: Span Calibration (if required)Apply a known pressure source to the HIGH and LOW ports.Adjust the span using the HART communicator:Device Setup > Calibration > Sensor Trim > Upper Sensor Trim.
Step 3: Verify Output,Check the 4-20 mA output corresponds to the applied pressure.7. Leak Testing
Step 1: Pressurize the SystemGradually increase process pressure to the maximum operating limit.
Step 2: Apply Leak Detection SolutionSpray soapy water on all threaded connections and valve stems.
Look for bubbles indicating leaks.
Step 3: Tighten as NeededIf leaks are detected, depressurize the system and retorque the affected connection.
8. Final CommissioningEnsure all valves are in their normal operating positions:
Block valves (1 and 2): OPEN
Equalizing valve (3): CLOSED
Bleed valves (4 and 5): CLOSED
Power on the transmitter and confirm stable readings on the control system.
9. Maintenance and Troubleshooting
Routine Checks:Inspect for corrosion or physical damage quarterly.Verify calibration annually or per site requirements.Common Issues:Zero Drift:Reperform zero trim.No Output:Check wiring, fuse, and loop resistance (≤ 600 Ω).Overrange Error:Confirm process pressure is within the transmitter's rated span.10. Safety and Shutdown
Emergency Isolation:Close block valves (1 and 2) to isolate the transmitter.Open bleed valves (4 and 5) to depressurize the manifold.Transmitter Removal:Depressurize the manifold and disconnect wiring before unbolting the transmitter. Company Profile
