The 8200-203est systema digitale protectionis contra velocitatem nimiam ex serie ProTech 203 Woodward, constructum ut systema instrumentorum tutelaris specialis pro turbinibus gasosis, turbinibus vaporificis, et aliis machinis rotativis altissimae velocitatis . The 8200-203monitorat velocitatem motoris primarii per tres sensus magneticos independientes (MPUs) et applicat logicam votationis 2-ex-3 ad initiandum interruptionem emergentem cum duo ex tribus canalibus confirmant conditionem velocitatis nimiae. The 8200-203features de-energize-to-trip fail-safe design, ensuring that loss of control power results in a safe (tripped) state rather than a dangerous failure mode . The 8200-203offers front-panel configuration, hot-swappable modules, and NEMA 4/4X enclosure for demanding industrial environments .
Triple-Redundant Architecture with 2oo3 Voting – Eliminates single points of failure; a single sensor or channel failure cannot cause either a spurious trip or a failure to trip . This architecture aligns with SIL requirements for critical machinery protection .
De-Energize-to-Trip Fail-Safe Design – Loss of control power, internal faults, or wiring failures result in a safe (tripped) state. Woodward strongly recommends this configuration for general safety .
Moduli Substituendi in Statu Operativo – Each speed-sensing unit can be replaced while the other two units remain powered and operational, eliminating costly downtime .
Built-In Self-Test Capability – On-board frequency generator permits testing of each unit individually while the prime mover remains on-line .
Praecisio Superior super Machinas Mechanicas – Sensus et indicatio velocitatis digitalis praecisionem ad 0.1% attingunt, quae longe excedit facultates machinarum mechanicarum contra velocitatem excessivam.
Paratus ad Ambientes Asperos – Cella NEMA 4/4X (IP54/IP65) cum pannello anteriori claudibili prohibet modificationes non autorizatas parametrorum salutis .
Tres Unitates Independentes Sensus Velocitatis – Quaeque suum proprium subministrationis electricae habet, et velocitatem motoris principalis continuo inspicit
logica Votationis Hardware 2-ex-3 – Sex relais votorum in ordine seriei/paralleli disposita; duae unitates debent activari ut turbinis cessatio incipiat
Logica De-Energize-to-Trip (Secura contra Defectus) – Relais interponens durante operatione normali excitatur; de-excitatur in casu velocitatis excessivae aut amissae potestatis
Interfacs Operatoris Panellis Anterioribus – Touchpad cum display LCD duarum linearum et sedecim characterum; claves Menu, Cursor Dexter, Adjust Sursum, et Adjust Deorsum
Programmatio Claviswitch-Protecta – Impedit mutationes configurationis non autorizatas; modus MONITOR pro operatione normali, modus PROGRAM pro configuratione
Generator Frequenticus Incorporatus – Permittit experimenta overspeed uniuscuiusque unitatis singulariter sine remotione primi motoris ab operatione
Indicatores Status LED Comprehensivi – Indicatores pro Trip, defectu MPU, defectu CPU, statu relais voter, et statu supplicationis electricae
Registratio Velocitatis Maximi – Capit et servat velocitatem maximam durante eventibus overspeed in memoria non-volatili
Gestio Defectus MPU – Punctum defectus MPU programmatibile et tempus exspectationis; optio programmabilis ad interrumpendum propter defectum
Capacitas Reinitiandi Remota – Permittit reinitiationem ab loco remoto per connexionem in campo
Clavis – Impedit programmationem vel experimenta non autorizata
Cassette Securabilis – Gradus IP54/NEMA 4 pro ambientibus industrialibus sine ullo controllo climatico addito
Supervisio Velocitatis Continua – Unumquodque trium unitatum sensuum velocitatis legat suum signum MPU et calculat velocitatem rotationis omni 5 ms
Detectio Supervelocitatis – Comparat velocitatem mensuratum ad punctum destinatum programmabile pro cursu (typice 110–115% velocitatis nominis); incitat trip quando duo ex tribus canalibus confirmant velocitatem nimiam
Detectio Amissae Signi – Detectio defectus MPU cum frequencia cadit sub 100 Hz postquam antea superavit 120 Hz; responsio programmabilis aut modo ad alarmam aut ad alarmam et trip
Temporizator Defectus MPU – Temporizator initiationis certificat quod velocitas superet punctum destinatum defectus MPU intra tempus programmatum; alioquin trip fit in motore primo
Actuatio Relais Voter – Unumquodque unitatis sensoris velocitatis actuatur duo relais voter; sex relais configurata in serie/parallelo ducunt relais interponens
Controllo Relais Trip – Relais interponens praebet duo contactus normaliter apertos et duo contactus normaliter clausos pro integratione cum systematibus externis actuandis
Testus Automaticus Incorporatus – Generator frequenciae in vehiculo permittit probationem velocitatis excessivae unitatum singularum dum systema manet in linea
Storatio Velocitatis Maximalis – Actualizat et servat velocitatem maximam in memoria non-volatili quando velocitas excessiva accidit
Annuntiatio Alarmis – Outputus alarmis separatus et LED indicant statum trip unitatis singularis; LEDs pro defectu MPU et defectu CPU informationem diagnosticam praebent
Detectio Defectuum Hardware – Monitoratio continua EEPROM, signorum interconnectionis, et functionis microprocessoris; trip in detectione faulti hardware
1: Quae sunt requisita potentiae ad introitum pro 8200-203?
A1: Ille 8200-203accipit introitum 120 Vac/dc, cum intervallo operationis 88–132 Vac aut 90–150 Vdc. Consumptio potentiae est 12.5 VA pro operatione AC et 4.77 W pro operatione DC .
Q2: Quae est differentia inter modulos de-energize-to-trip et energize-to-trip?
A2: In modulis de-energize-to-trip ut 8200-203 8200-203, the trip relay is energized during normal operation and de-energizes on overspeed or power loss—ensuring a safe (tripped) state if control power is lost . Woodward strongly recommends de-energize-to-trip for general safety . Energize-to-trip models require power to trip and may not trip on power loss.
Q3: Can individual units be replaced without shutting down the turbine?
A3: Yes. The ProTech 203 system features hot-swappable modules. Each speed-sensing unit can be replaced while the other two units remain powered and operational, allowing on-line maintenance without tripping the prime mover .
Q4: What is the speed sensing frequency range of the 8200-203?
A4: The speed-sensing frequency range is 100 Hz to 32 kHz, with a trip-point frequency range of 250 Hz to 25 kHz. The minimum MPU input amplitude is 1 Vrms from 100 Hz to 25 kHz, and 2 Vrms from 25 kHz to 32 kHz .
Q5: How does the 2-out-of-3 voting logic improve system reliability?
A5: Logica votationis 2-ex-3 requirit ut duo ex tribus canalibus independentibus sensus velocitatis conditionem supervelocitatis detegant antequam trip initietur. Haec eliminat puncta unica defectus—defectus unius sensoris neque tripum spurium neque defectum tripandi causare potest, quod fiduciam systematis multum augent et tempus inutile inactivitatis praevinet. .
