FUNCTIONAL DESCRIPTION OF IS220PVIBH1A, REV G:

The IS220PVIBH1A, REV G is a Vibration Monitor Board designed and manufactured by General Electric for the Distributed Mark VIe turbine control Systems. The PVIB provides the electrical interface between one or two I/O Ethernet networks and the TVBA vibration terminal board. The pack contains a processor daughterboard. The pack uses channels 1 through 8 to read vibration or proximity information from the following sensor types: Proximitors, accelerometers with an integrated output (Channels 1-3 only), Velomitor, or seismics. Channels 9 through 12 only support proximitors, and channel 13 can input either a Keyphasor signal type or a proximity-type signal. Input to the pack is through dual RJ45 Ethernet connectors and a 3-pin power input. The PVIB supports dual Ethernet networks for frame rates slower than 100 Hz. It supports a single Ethernet network for frame rates of 3.125, 6.25, 12.5, 25, 50, and 100 Hz. Output is through a DC-37 pin connector that connects directly with the associated terminal board connector. Visual diagnostics are provided through indicator LEDs, and local diagnostic serial communications are possible through an infrared port.

INSTALLATION:

• Directly plug one PVIB I/O pack for simplex or three PVIB I/O packs for TMR into the terminal board connectors.
• Mechanically secure the packs using the threaded studs adjacent to the Ethernet ports. The studs slide into a mounting bracket specific to the terminal board type.
• The bracket location should be adjusted such that there is no right-angle force applied to the DC-37 pin connector between the pack and the terminal board. The adjustment should only be required once in the life of the product.
• Plug in one or two Ethernet cables depending on the system configuration. The pack will operate over either port. If dual connections are used, the standard practice is to connect
• ENET1 to the network associated with the R controller.
• Apply power to the pack by plugging in the connector on the side of the pack. It is not necessary to insert this connector with the power removed from the cable. The I/O pack has inherent soft-start capability that controls current inrush on power application.
• Verify that the TVBA's N28 power supply daughterboard is seated properly in the TVBA connector.

OPERATION:

The processor application code contains all the logic necessary to allow the pack to operate from one or two Ethernet inputs. When operated from two Ethernet inputs, both network paths are active all the time. A failure of either network will not result in any disturbance to the I/O pack operation, and the failure will be indicated through the working network connection. This arrangement is more tolerant of faults than a classic hot-backup system where the second port is only used after a primary port failure is detected. The Ethernet ports on the processor auto-negotiate between 10 MB/s and 100 MB/s speed, and between half-duplex and full-duplex operation. An industry-standard infrared serial communications port is provided on the processor board. Accessible through the pack front, this port provides diagnostic information on the pack status and the ability to program the pack when both Ethernet connections fail. It is possible to communicate with this port using most notebook computers and most hand-held Personal Digital Assistants (PDA).

• High-speed processor with RAM and flash memory
• Two fully independent 10/100 Ethernet ports with connectors
• Hardware watchdog timer and reset circuit
• Local ambient temperature sensor
• Infrared serial communications port
• Status-indication LEDs
• Electronic ID and the ability to read IDs on other boards
• Substantial programmable logic supporting the acquisition board
• Input power connector with soft start/current limiter
• Local power supplies, including sequencing and monitoring

VIBRATION MONITORING APPLICATION FIRMWARE:

Channels 1 through 3 can be used for position information from Proximitors, wideband vibration information from Proximitors, accelerometers with integrated outputs, Velomitors, and Seismics. 1x and 2x information can be derived from Proximitors viewing axial vibration information when a Keyphasor is used. Tracking filters are normally used in Mark V LM control applications. Gapx_Vibx_Wideband_Filtering runs every 10 ms, activating the low-pass filter for the gap calculation, the wideband vibration filter, and the maximum/minimum detection for the peak-to-peak calculation. The Gap Scaling and Limit Check runs at the frame rate. This function converts the gap value from counts to the desired engineering units (EU). The system limit check provides the user with two detection limits and Boolean outputs for the status. The Vibx Wideband Scaling and Limit Check block runs every frame. The peak-to-peak calculation is based on the Vmax and Vmin values of the Gapx_Vibx Wideband Filtering. The wideband peak-to-peak signal is filtered and then scaled to EU. The re-scaled wideband peak-to-peak signal is then run through a limit check. The limit check provides the Booleans, SysLim1VIBx and SysLim2VIBx, for the limit check status.
