for SY-MFT Series Actuators

3 Configuration

On the "Configuration" tab, you can read

out parameter values from the actuator,

change them and save them back to the

actuator. The valid ranges for the

parameter values are displayed in

parentheses next to the input boxes.

What is “Loss of Signal” functionality?

This is the point at which the SY actuator interprets no input from the controller and either stops, closes or opens the

valve based on the programmed control functionality.

Loss of signal point is always at 0.5V. It doesn’t matter if the control signal is 2-10V or 0.5-10V.

Loss of signal point is 1mA if 4-20mA is selected.

Loss of Signal – Stop The actuator will stop in its last position.

Loss of Signal – Open The actuator will move to its 100% position.

Loss of Signal – Close The actuator will move to its 0% position.

Loss of Signal – Nothing The actuator will move to the zero position.
