Frequently Asked Questions
- Q: What is the difference between single and double acting?
Single acting uses one output. Double acting uses two outputs for push-pull. - Q: Can I use this positioner with HART communicators?
Yes. HART Protocol 5.1 is fully supported. - Q: What is the minimum input current for operation?
3.4 mA without feedback, 3.5 mA with feedback. - Q: Is this unit suitable for SIL2 applications?
Yes. It meets SIL2 requirements for safety loops. - Q: What approvals does this model have?
ATEX, FM, CSA, IECEx, and CE mark.
Experience-based Q&A
- Q: The positioner does not respond. What should I check?
Verify the 4..20 mA signal and air supply pressure. Check the fault LED. - Q: How to perform auto-calibration?
Press the single button. The unit will automatically find travel limits. - Q: The output pressure is unstable. What is wrong?
Check air supply quality. Also verify the actuator for leaks.
Selection Guide
- For linear actuators, choose standard mounting to DIN/IEC 534.
- For rotary actuators, select mounting to VDI/VDE 3845.
- For HART communication, model includes FSK module.
- For explosion-proof areas, consider options with intrinsic safety.
