 AT-3000 Plasma Control System

The AT-3000 Plasma Control System is designed with all considerations towards user-friendly and safe operation. Using PLC and Touchscreen control, the user can take advantage of many features that aid in the plasma process, such as: automatic start-up and shutdown sequences, an hour meter and settable maintenance alarm, and a series of built-in process alarms and warnings.

The system is designed with safety in mind, such that the AT-3000 can safely run Hydrogen as a secondary gas. The AT-3000 features a built-in user-operated Safety Purge System. This purge system allows a user to power up the console into a safe condition. All of the components of the system are designed so that all electrical signals and power entering and leaving the AT-3000 console during purging are deactivated. This insures that a dangerous condition prior to purging does not exist. From alarm and warning settings that include automatic safety shutdown sequences, to external components that send alarm feedback to the console, the AT-3000 system is designed with safety and ease of use in mind.
