How to calibrate the input signal of the actuator?

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 […]

Using IoT to Monitor and Analyze Intermittent Actuator Failures

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 […]
