6.1.3.4 Uncontrolled movements
In the following cases, the valve disc's position may change in an uncontrolled
manner due to the system's pressure with resultant effects on the plant:
▪
Control failure
▪
Signal error
▪
Power supply failure during operation
▪
Incorrect actuator setting
▪
Deactivation of the position switches in the actuator
