The TS310 is a 1 or 2 valve, user configurable control system that provides complete control for simple or complex prime movers. The functional objective of the TS310 is to supply multiple control loops necessary for safe and accurate control. The TS310 system has field configurability, allowing it to provide the necessary functions to control a two-valve steam turbine or a single-valve steam turbine with Anti Surge Control or reciprocating engines. These functions take in speed, process and safety control.

The system is a simplex microprocessor-based controller with standard software to provide the required controls and functions. It is designed to provide precision control, high reliability and ease of maintenance. Contact output hardware consists of solid state devices. An option for dry contacts is also available.

The TS310 has a sealed membrane-type keypad to provide the means for field configuration and operation. This keypad is of a weather-tight design. The system provides a liquid quartz display for the viewing of the configuration and operation of the system.

The system provides hardware for expansion via an RS422 communication port. The TS310 is a rugged, field-proven configurable steam turbine governor that provides pre-programmed control for one-valve and two-valve (extraction) steam turbines. Using the Windows-based PC Configurator, or from the front keypad, the user can quickly configure the TS310 for a wide range of steam turbine control applications, including:

  • Inlet pressure control
  • Extraction/admission control
  • Backpressure control

The TS310 can also be configured for driven-equipment control applications, including:

  • Suction pressure control
  • Discharge pressure control
  • Synchronous (isochronous and droop) generator control
  • Paper line drive control
  • Compressors
  • Pump drivers
  • Generators
  • Hydro-turbines
  • FD/ID fans

  • Nozzle valve control
  • Load limiting
  • Critical speed band avoidance
