        More Information

        Overview Manuals Overspeed Logic Synchronizing Trip Interfaces Field Verification

        Features:

        • Measures four magnetic speed-pickup channels for control and fast overspeed protection.
        • Combines generator and bus PT signals with breaker feedback for synchronization.
        • Interfaces eight flame detectors and three trip-solenoid driver paths through Mark VI trip hardware.
        The VTUR processor brings turbine speed, generator phasing, breaker state, flame status, and trip commands into one coordinated VME function.

        Its fast overspeed path can initiate protective action within 30 ms when the configured limit is exceeded, while the controller continues to receive detailed status and diagnostic data.

        Simplex and TMR racks use different signal distributions, so cable destinations and terminal assemblies must match the installed project rather than a generic board diagram.

        Apter Power supplies the General Electric IS200VTURH1B VME Turbine Interface Board for qualified Mark VI maintenance and replacement requirements.

        Fast protective speed path

        • Inputs: Four pulse-rate channels accept independent magnetic pickups.
        • Decision basis: Configured speed constants convert pulse frequency to shaft speed.
        • Trip timing: The fast path is designed to act within 30 ms.
        • Redundancy: TMR logic compares the available speed evidence across protection paths.
        • Validity: Missing pulses, noise, or wiring faults must be distinguished from true overspeed.
        • Disagreement check: A channel disagreement should lead first to pickup waveform, polarity, air-gap, and cabling checks, followed by comparison of the configured constants used by IS200VTURH1B.

        Generator-to-bus matching

        • Voltage references: Generator and bus PT channels supply the synchronization measurements.
        • Breaker state: The interface tracks breaker feedback used by the permissive sequence.
        • Phase relationship: Phasing and polarity must agree with the plant drawings.
        • Control outcome: Synchronizing logic depends on valid voltage, frequency, and breaker information.
        • Diagnostic sequence: If automatic synchronization stalls, compare PT levels and phase rotation, then trace the breaker indication into IS200VTURH1B before modifying the controller application.
        • Cable preservation: A board exchange should preserve the existing TTUR cable mapping so generator and bus references are not inadvertently reversed.

        Protective I/O boundary

        • Flame circuits: Eight detector inputs enter through the trip-terminal hardware.
        • Trip outputs: Three solenoid-driver paths support the shutdown architecture.
        • Terminal assemblies: TTUR and TRPG hardware connect the field devices to the VME processor.
        • Fail-safe review: Supply, fuse, solenoid, and feedback checks remain part of diagnosis.
        • Hardware identity: Connected board type and revision must match the downloaded configuration.
        • End-to-end proof: IS200VTURH1B status alone cannot prove the health of a flame detector or trip solenoid; terminal power and end-to-end field continuity are required evidence.

        Commissioning checkpoints

        • Rack record: Preserve slot number and R/S/T cable destinations before removal.
        • Speed channels: Confirm pickup polarity, air gap, and plausible running speed.
        • PT channels: Verify generator and bus phasing before synchronization is enabled.
        • Trip path: Check flame indications, trip commands, solenoid continuity, and feedback.
        • Final state: Require a healthy RUN indication and cleared hardware-identification alarms.
        • Return-to-service proof: Return IS200VTURH1B to service only after controller values agree with independent field observations and the approved turbine test procedure.
        Description
        The General Electric IS200VTURH1B VME Turbine Interface Board is the SPEEDTRONIC Mark VI rack module that unites shaft-speed protection and generator synchronizing.

        Four pulse-rate inputs accept magnetic speed pickups, while the generator and bus potential-transformer channels provide the phase information needed for synchronization. Additional shaft current or voltage monitoring and breaker-interface paths give IS200VTURH1B a direct role at the boundary between the turbine, generator, and protective hardware.

        Eight flame-detector inputs are brought through the trip-terminal assembly, and three independent trip-solenoid driver paths support the protective shutdown architecture. The documented fast overspeed response allows IS200VTURH1B to initiate the trip path within 30 ms when the configured speed limit is exceeded.

        Simplex or TMR implementation changes the way speed, trip, and synchronizing signals are distributed, but it does not replace field verification. Correct TTUR/TRPG interfaces, pickup polarity and air gap, potential-transformer phasing, and downloaded hardware identity all need confirmation before IS200VTURH1B is returned to service.

        FAQS

        The following is a list of questions commonly asked by our customers. Please contact us if you have a question about our process that is not answered below.
        VIEW ALL FAQS
        Why does IS200VTURH1B show zero or unstable shaft speed?
        Check magnetic-pickup wiring, polarity, air gap, connector seating, and channel diagnostics before replacing IS200VTURH1B; weak or noisy pulse signals can produce the same symptom.
        How should an overspeed disagreement involving IS200VTURH1B be investigated?
        Compare all available speed channels, verify the configured overspeed constant, and inspect pickup signal quality so IS200VTURH1B is not blamed for a field-sensor mismatch.
        What should be checked when IS200VTURH1B cannot complete generator synchronization?
        Confirm generator and bus PT phasing, amplitude, breaker feedback, and the synchronizing permissives received by IS200VTURH1B before adjusting the control logic.
        Why might a trip solenoid remain energized with IS200VTURH1B installed?
        Review the IS200VTURH1B trip commands, TRPG supply and fuses, solenoid continuity, and feedback state because a healthy VME board cannot overcome an open field path.
        How can a flame-input fault on IS200VTURH1B be separated from a detector problem?
        Trace the affected flame-detector circuit through the terminal assembly, compare neighboring channels, and review IS200VTURH1B diagnostics before exchanging the board.
        What should be recorded before replacing IS200VTURH1B in a TMR rack?
        Document the IS200VTURH1B rack position, R/S/T cable destinations, TTUR/TRPG hardware revisions, and project configuration so the replacement preserves the approved trip topology.
        What should a technician verify after installing IS200VTURH1B?
        After powering the rack, confirm IS200VTURH1B RUN status, healthy terminal identification, plausible speed and PT readings, breaker feedback, and a cleared trip path before enabling operation.
