Configuring and calibrating the ABB TZIDC positioner involves several steps. Here's a general outline of the process:
#Configuration: Faisal Ahmed I&C
Mounting: Attach the TZIDC positioner to the valve actuator according to the manufacturer's guidelines.
Electrical Connections: Ensure proper wiring of power supply, control signals, and communication interfaces.
#Communication: If applicable, configure communication protocols (such as HART or Profibus) between the positioner and the control system.
Basic Settings: Set parameters such as supply voltage, fail action, and units of measurement.
#Calibration:
Zero Point Calibration: Adjust the positioner to the valve's #closed position (fully shut). Initiate a zero calibration to establish the closed position reference.
Span Calibration: Adjust the positioner to the valve's fully open position. Initiate a span calibration to define the open position reference.
Travel Calibration: Command the valve to several intermediate #positions (e.g., 25%, 50%, 75%) and verify that the positioner's feedback matches the actual valve position.

Linearity Check: Confirm that the positioner responds linearly to input #signals over the valve's operating range #TZIDC
Hysteresis Check: Test the positioner's ability to consistently return to the same position when approached from different directions.
Please note that these are general steps and the actual procedure may vary depending on the valve, actuator, and communication protocols used. Always refer to the official ABB TZIDC documentation or user manual for precise instructions tailored to your specific setup. It's also recommended to involve qualified personnel for installation, configuration, and calibration to ensure safety and accuracy
