Frequently Asked Questions (FAQ)
- What is the main benefit of HART communication?
It allows digital setup and monitoring without breaking the analog signal loop. - Is this positioner suitable for outdoor use?
Yes. The IP65 rating protects against dust and water jets for outdoor areas. - What does “fail-freeze” do?
If power fails, it locks air pressures to hold the valve in the last safe position. - How do I pick direct or reverse action?
Choose direct for 4 mA to close the valve. Pick reverse for 4 mA to open it. - Is analog feedback included in this model?
Yes. The V18345-1020521001 model includes the analog feedback module by default.
