FUNCTIONAL DESCRIPTION:

IS200TVIBH2BCC is a Vibration Input Terminal Board manufactured and designed by General Electric as part of the Mark VI Series used in GE Speedtronic Turbine Control Systems. The Vibration Input (TVIB) terminal board accepts up to 14 vibration probes, two of which can be cabled directly to the VVIB board. VVIB processes and digitizes the displacement and velocity signals, which are then sent over the VME bus to the controller. The Mark VI system uses Bently Nevada probes for shaft vibration monitoring. The following vibration probes are compatible with TVIB:

• Proximity
• Velocity
• Acceleration
• Seismic
• Phase

There are two variants of TVIB terminal boards: the H1A and H2A. The H2A board is equipped with BNC connectors, enabling the connection of portable vibration data collection equipment for predictive maintenance. Both types allow for permanent connection to Bently Nevada vibration monitoring equipment via connectors, which are used for measuring and analyzing turbine vibration. Within the Mark VI system, the TVIB board operates alongside the VVIB processor and is compatible with both simplex and TMR configurations. In simplex setups, two cables connect two TVIBs to the VVIB processor, while in TMR systems, three cables link the TVIB to three separate VVIB processors.

INSTALLATION:

Attach the wires from the 14 vibration probes to the two terminal blocks, with each probe using three wires. In simplex systems, connect the TVIB1 JR1 connector to the VVIB J3 connector on the VME rack, and connect the TVIB JR1 connector to VVIB J4. For TMR systems, connect the VVIB JR1, JS1, and JT1 connectors to the R, S, and T VVIB processors. Use jumpers JP1 through JP8 to set the probe type for the first eight probes. Optionally, connect the TVIB to a Bently Nevada system via connectors JA1, JB1, JC1, and JD1.

OPERATION:

TVIB is compatible with Bently Nevada’s Proximitor, Seismic, Accelerometer, and Velomitor probes, with power supplied to these probes from VVIB boards in both simplex and TMR modes. Probe signals return to VVIB, where they are A/D converted and sent via the VME bus to the controller, which generates vibration, eccentricity, axial position alarms, and trip logic. A -28 V dc supply from the VME board powers Proximitor probes, and in TMR configurations, a diode high-select circuit ensures redundancy by selecting the highest -28 V dc bus. Individual regulators provide protected excitation sources ranging from -23 to -26 V dc, while VVIB samples probe inputs at high speed over set intervals.

FREQUENTLY ASKED QUESTIONS:

How is the TVIB terminal board powered in simplex and TMR systems?

In both simplex and TMR configurations, power for the vibration probes is provided by the VVIB boards. Additionally, a -28 V DC supply from the VME board powers the Proximitor probes.

What is the purpose of the BNC connectors on the H2A TVIB board?

The H2A board includes BNC connectors to allow portable vibration data-gathering equipment to be connected for predictive maintenance.

How does the TVIB terminal board connect in a simplex setup?

In simplex systems, TVIB1 connects to the VVIB J3 port, and the main TVIB connects to VVIB J4 on the VME rack.
