Features:
- Electronic identification checks the installed turbine terminal board before normal operation begins.
- Auto-Reconfiguration can restore the approved pack configuration after a service replacement.
- Front indicators separate pack health from the activity of the two I/O Ethernet paths.
Electronic ID information prevents an incompatible terminal combination from silently entering service. A mismatch remains visible to maintenance personnel instead of being treated as valid turbine data.
Network and pack diagnostics distinguish a lost Ethernet path from a local hardware or terminal-interface problem. That separation helps technicians narrow the fault before disturbing field wiring.
Replacement work can use the controller's stored configuration when Auto-Reconfiguration is enabled, reducing the manual recovery steps required after installing an approved spare.

How PTUR handles protective speed decisions
- Signal conditioning: Each magnetic-pickup waveform is converted into speed information before it reaches the controller frame.
- Primary paths: Dedicated protection channels preserve independent overspeed decisions instead of relying only on normal control logic.
- Low-speed observation: Turning-gear behavior remains visible below the normal turbine operating range.
- Fast algorithms: PR_Single and PR_Max use direct pack processing when an emergency response cannot wait for slower sequencing.
- Voted action: A three-pack arrangement lets the controller reconcile separate R, S, and T protection paths before issuing a trip.
Breaker-closing information handled by PTUR
- Voltage comparison: Compatible TTUR hardware supplies both bus and generator measurements for synchronization logic.
- Phase tracking: The control system evaluates angular difference rather than closing the breaker from voltage magnitude alone.
- Slip prediction: Relative frequency is used to predict when the two rotating references will coincide.
- Closure timing: Breaker operating delay is considered so the contacts meet near the intended zero-angle point.
- Monitor mode: Synchronizing behavior can be observed without issuing the final breaker command during commissioning checks.
Finding faults without disturbing turbine wiring
- Pack health: The attention indicator directs technicians to internal or configuration diagnostics rather than a network-only problem.
- Network isolation: Separate link and transmit indications show whether either Ethernet path is carrying controller traffic.
- Terminal identity: An electronic-ID mismatch flags unsuitable terminal hardware before its signals are accepted.
- ToolboxST detail: Device and channel diagnostics separate a sensor issue from a board, pack, or communication alarm.
- Replacement recovery: Auto-Reconfiguration can reload an approved setup when a compatible spare takes the failed pack's place.
Protected turbine and generator functions
- Gas turbines: A TRPG trip-board arrangement applies PTUR speed protection to gas-turbine emergency shutdown paths.
- Steam turbines: TRPS hardware supports the trip architecture used on small and medium steam-turbine units.
- Large steam units: TRPL arrangements extend the primary trip function to large steam-turbine installations.
- Generator synchronization: A TTUR-based configuration contributes voltage, phase, slip, and breaker-command information for automatic synchronization.
