Professional FAQ & Procurement Guide

• What happens to the valve position if the 4-20mA signal is lost?
• The fail-freeze function locks the pneumatic output, maintaining the current valve position until power is restored.
• Can I use this positioner in an explosive environment (ATEX)?
• No, the V18345-1010221001 is the “0” explosion protection variant; contact us for intrinsically safe versions.
• Does this model support split-range configurations for dual-valve setups?
• Yes, the intelligent software allows split-range settings between 20% and 100% of the nominal signal.
• What is the minimum current required for the positioner to operate with feedback?
• With the analog feedback module installed, the unit requires a minimum start-up current of 3.5 mA.
• Experience Tip: How often should I check the air supply filters for this unit?
• To prevent blockage in the intelligent I/P module, inspect air filters every 6 months or according to your local air quality.
