- Power & Water Treatment: Boiler steam control, circulating water regulation and municipal sewage treatment valve automation.
Common Problems & Solutions
No response to input signal
Solution: Inspect 4-20mA wiring and power supply; verify air supply pressure and check pneumatic lines for leakage.
Inaccurate valve positioning
Solution: Re-execute Quick-Cal automatic calibration; check stroke linkage and position sensor for mechanical misalignment.
Unstable HART communication
Solution: Confirm cable impedance and length within specification; eliminate electrical interference and check IS barrier compatibility.
