The 310SV is a configurable controller that provides automatic startup sequencing, speed control, and process control for a single-valve steam turbine driving a mechanical load (e.g. pump, fan, compressor).
The user can choose from a wide selection of control options to match the turbine operational requirements.
Major features include:
- Completely automatic turbine startup
- Eight configurable speed bands, each with separate ramp rates and idle times
- Critical speed band avoidance
- Startup, Run, Droop, and Overspeed Test tuning constants for the Speed PID
- Process PID for control of process suction or discharge measurements
- Local and remote speed and process setpoint control
- Rugged front panel operator interface
- Flexible, configurable I/O
- Modbus serial data communications
- Powerful PC Configurator
Front Panel Operator Interface
The enclosure, front panel display, and rugged pushbuttons and selector switch are all rated NEMA 4 for outdoor installations. From the front panel, the operator can:
- Start and stop the turbine
- Perform overspeed trip testing
- Enable/disable process control
- Change speed and process setpoints
- Monitor analog I/O values
- View and acknowledge alarms
Flexible, Configurable I/O
The 310SV continues the Triconex tradition of flexible, configurable I/O for turbomachinery controllers. It includes six flexible, digital I/O points, each configurable as a digital input or output by selecting the corresponding plug-in module. Input and output modules are available with a comprehensive range of voltages and current specifications to meet the requirements of almost any application. The user may choose from 17 input functions and 18 output functions (including nozzle valve control) for each flexible digital I/O point. The 310SV also includes five separate remote digital inputs that can each be configured from a list of 17 input functions. The remote digital inputs make it easy to connect a group of 24V DC digital inputs from a remote control panel with configurable functions like start, stop, speed raise/lower, halt, continue, idle/run, and alarm acknowledge.

Powerful PC Configurator
The 310SV Configurator is a Windows-based software application that allows the user to configure the controller from a PC. The Configurator makes setup easy with features like an expandable parameter view, drop down menus, and check boxes. Detailed online help minimizes the need to refer to the User’s Guide during configuration. Configurations can be easily downloaded/uploaded to/from the 310SV. A comparison feature makes it easy to recognize the differences between two configuration files.
The 310SV Configurator allows real-time monitoring of I/O values and states, calculated values, and alarm and trip history. Selectable real-time trending and recording are also available.
One of the most powerful features of the Configurator is the Simulate mode, which allows the user to test a configuration on the PC, without running the turbine or even connecting to the 310SV controller. The user can simulate a turbine startup and confirm configured speed ranges, ramp rates, and digital I/O functions without leaving an office environment. The Simulate mode can also be used as a tool to train technicians and operators.
