Product Description

Tavsif

Bently Nevada 87890-01 — Bently Nevada 3300 mashina monitoringi stendlari uchun 3300/03 tizim monitorida ishlatiladigan monitor konturi yig‘ilmasi.

Yig‘ilma stend darajasidagi monitoring va boshqaruv funksiyalari uchun mas’ul tizim monitori elektronikasining bir qismidir. 3300 arxitekturasi 3300 monitoring tizimida System Reset, Inhibit, OK, Trip Multiply va Keyphasor bilan bog‘liq funksiyalarni ta’minlaydi.

Tizim monitori stend OK mantiqini ham muvofiqlashtiradi. Alohida monitorlarning OK relesi drayverlari stend OK shinasiga signal uzatadi, tizim monitori va quvvat kirish moduli esa yakuniy OK relesi holatini belgilaydi.

87890-01 yig‘ilmasini almashtirishda o‘rnatishdan oldin to‘liq 3300/03 katalog konfiguratsiyasi va barcha modifikatsiya ma’lumotlari aniqlanishi kerak. Dasturlanadigan opsiyalar dastlabki tizim monitori konfiguratsiyasiga mos kelishi shart.

FAQ

What is the Bently Nevada 87890-01?

The Bently Nevada 87890-01 is the Monitor Circuit Assembly used inside the 3300/03 System Monitor. It is listed as a separate replacement part rather than a complete System Monitor.

Is the Bently Nevada 87890-01 a complete 3300/03 System Monitor?

The Bently Nevada 87890-01 is not identified as the complete 3300/03 System Monitor. Bently Nevada lists 87890-01 as the Monitor Circuit Assembly, while the front panel assembly is a separate spare part.

What functions are associated with the 3300/03 System Monitor?

The Bently Nevada 3300/03 System Monitor architecture provides rack-level functions including System Reset, Inhibit, OK relay logic, Trip Multiply, and Keyphasor-related functions.

What should be checked before replacing a Bently Nevada 87890-01?

The Bently Nevada 87890-01 replacement should match the complete 3300/03 catalog configuration and any modification number. Existing programmable options and the -VT setting should be recorded before removal.

Why must the -VT setting be checked during 87890-01 replacement?

The Bently Nevada 87890-01 operates within a 3300/03 configuration that can use -18 Vdc or -24 Vdc transducer power. The System Monitor and Power Supply must use matching -VT settings.

Does the 87890-01 handle the rack OK relay directly?

The Bently Nevada 87890-01 participates in the 3300/03 rack OK logic. Monitor OK relay drives feed the OK bus, while the System Monitor and Power Input Module determine the rack OK relay condition.
