Fail-Action Test
Features:
- ABB ordering code V18345-1010421001 identifies a TZIDC digital electropneumatic positioner; the complete code must be retained for the installed option set.
- Confirm the full ordering code, control-valve tag, actuator action and travel, mounting geometry, air supply, two-wire loop and all fitted options.
- Use this execution only on the documented valve assembly whose mechanical and control-loop design was engineered for V18345-1010421001.
V18345-1010421001 must be matched to the receiving equipment and project record. Preserve the identified mounting hardware, air-port arrangement, linkage, signal wiring, grounding and cable entries during replacement. Run autoadjust and verify 4–20 mA response, travel direction, calibrated end points, feedback, alarms and safe failure behavior.
