2.10 Interlock Control
For high-demand scenarios, the actuator is ingeniously configurable for conditional control, ensuring optimal performance.
In this advanced mode, operations hinge on the coordination of two distinct signals. For instance, when both a remote close input signal and a close interlock input signal are present, the actuator decisively closes the valve. Should only one signal be available or a signal be lost, the actuator will prudently hold or halt to avert failure. For critical applications necessitating ESD, a dedicated ESD input is provided, taking precedence over all local or remote control signals, thereby nullifying any active or incoming control signals upon its application.
