5 Professional FAQs

• What does “double acting, fail safe” mean on this positioner?
• Double acting means it drives both sides of the actuator. Fail safe means it moves to a safe position when power fails.
• Can I use this positioner without the LKS adapter?
• Yes. The LKS port is optional for PC connection. You can configure fully using the onboard panel.
• What is the minimum supply pressure for reliable operation?
• Use at least 1.4 bar (20 psi). Below this, the positioner may not move the valve fully.
• Do you offer the mechanical kit for digital feedback (option 0)?
• This unit comes without digital feedback kit. Please contact us if you need to add this feature.
• How do I select the right temperature class for my plant?
• For ambient above 50°C, choose T4. For outdoor cold climates, all classes work down to -40°C.

Selection Guide – Pick the Right TZIDC Positioner

• Step 1 – Actuator type: Choose code 1 (this model) for linear or rotary mounting.
• Step 2 – Explosion protection needed: Code 0 has no protection. For Zone 1, choose a model with intrinsic safety code.
• Step 3 – Output type: Code 4 gives double acting fail safe. For single acting, pick other codes.
• Step 4 – Connections: Code 2 gives NPT threads. For metric threads, choose different code.
• Step 5 – Feedback option: Code 1 includes analog 4-20 mA feedback. Add digital feedback kit if needed.
• Pro tip: For very dusty or wet areas, the IP65 housing works well. Add an air filter regulator before the positioner for best reliability.
