Installation and Wiring Guidelines

Proper installation of the ABB V18347-2041150001 ensures reliable valve control. Follow these key points.

• Mounting: Attach to linear actuators per DIN/IEC 534/NAMUR standard. For rotary actuators, use VDI/VDE 3845 mounting.

• Electrical Wiring: Use screw terminals for connections. Do not expose the terminals to mechanical strain.

• Wire Sizes: Max 1.0 mm² for option modules. Max 2.5 mm² for the analog signal.

• Cable Entry: Use the provided M20x1.5 cable gland. The second entry has a pipe plug.

• Pneumatic Tubing: Connect air supply using 1/4-18 NPT fittings. Use G 1/4 threads for other regions.

• Grounding: Properly ground the aluminum case for safety and noise immunity.

• Air Supply Quality: Use clean, dry instrument air for reliable operation.

• Configuration: Use the operator panel for local configuration. Use FOUNDATION Fieldbus for remote setup.

Foundation Fieldbus Communication

The ABB V18347-2041150001 uses FOUNDATION Fieldbus for digital communication. This protocol allows two-way communication between the positioner and your DCS. You can monitor valve position, set parameters, and diagnose issues remotely. The V18347-2041150001 supports device description (DD) files for easy integration. Foundation Fieldbus reduces wiring costs compared to analog 4-20 mA systems.

ATEX Approval for Hazardous Areas

This ABB V18347-2041150001 has ATEX EEx ia IIC T6 certification. The "ia" rating means intrinsic safety for Zone 0, 1, and 2 hazardous areas. Gas group IIC covers hydrogen and acetylene. Temperature class T6 is safe for surfaces up to 85°C. The V18347-2041150001 is ideal for petrochemical, refinery, and gas applications.

Fail-Safe Single Acting Operation

The ABB V18347-2041150001 is a single acting fail-safe positioner. In case of electrical power failure, the unit moves the valve to a safe position. This is critical for emergency shutdown situations. Single acting operation requires only one pneumatic output. The V18347-2041150001 controls spring-return actuators perfectly.
