Comment calibrer le signal d'entrée de l'actionneur ?
When the actuator’s valve position does not match the 4–20mA input signal (resulting in a discrepancy between the feedback signal and the input signal), you can calibrate the input signal to eliminate this deviation. 6 Simple Steps for Calibration: Turn the S-A switch to position 2. Press and hold the Set button until the L2 […]
Utilisation de l'IdO pour surveiller et analyser les défaillances intermittentes des actionneurs
Customer Feedback: The Three-Way Valve in the Cooling System Failed to Reach the Designated Position A nuclear power customer reported an intermittent failure of the actuator. Specifically, after the control system issued an opening command via a 4-20mA signal, the actuator’s feedback position remained unchanged. Upon cutting off the power and inspecting the site, the […]
