What to do if a change in valve position setpoint doesn't affect the actuator position in a Metso Controller?

If a change in the valve position setpoint does not affect the position of the actuator, consider the following potential causes: * The spool valve might be sticking. * The actuator and/or valve could be jammed. * The signal wires might be incorrectly connected, resulting in no value being displayed. * The circuit boards could be defective.
