X2 - V1.4


Vector Controls X2 Operating System Version 1.4

X2-Operating System

The X2-Operating system consists of a standardized method to operate and configure a range of controllers and sensors. The system is built on pre-programmed control and function blocks which can be configured using a parameterization routine. All X2-type products use the same philosophy and can be configured using the same tools and methods. All X2-type products can be configured using the standard operation terminals, the PC based tool EasySet™ from Vector Controls or remotely through bus communication where available.
