Functional Description:

The IS200TSVOH1BAA is a servo I/O terminal board www.cniacs.com manufactured and designed by General Electric as part of the Mark VIe series used in GE’s distributed turbine control systems. The servo input/output (TSVO) terminal block is connected to two electrohydraulic servo valves that actuate steam/fuel valves. The valve positions are measured using LVDTs. Two cables are connected to the VSVO using the J5 plug on the front of the VSVO and the J3 or J4 connectors on the VME rack. the TSVO provides a simplex signal through the JR1 connector and fans out the TMR signal to the JR1. JS1 and JT1 connectors. Plugs JD1 or JD2 are used for external tripping of the protection module.

Installation:

Connect the sensor and servo valve wires directly to the two I/O terminals on the terminal block as shown in Figure Servo Terminal Block Wiring. Each module is secured with two screws and has 24 terminals that accept wiring up to #12 AWG. The shield terminal strip connected to chassis ground is immediately to the left of each terminal. Connect the external trip wires to JD1 or JD2. Connect the J5 connector to the front of the VSVO board in racks R, S, and T. Connect the J5 connector to the front of the VSVO board in racks R, S and T. Connect the J1 connector to the VME rack underneath the VSVO in racks R, S, and T.

Operation:

The VSVO provides four channels including bi-directional servo current outputs, LVDT position feedback, LVDT excitation, and pulse rate flow inputs.The TSVO provides excitation for, and accepts inputs from, up to six LVDT valve position inputs. One, two, three, or four LVDTs can be selected for each servo control loop, and if three inputs are used, they can be used for gas turbine flow measurement applications. These signals are transmitted through the TSVO and sent directly to the front of the VSVO board at J5. Each servo output is equipped with a firmware-controlled, independent suicide relay that short-circuits the VSVO output signal to common in the event of a power failure and returns it to the nominal limit when a manual reset command is issued. Diagnostics monitor the output status of each servo voltage, current, and suicide relay.

Description:

General Electric’s IS200TSVOH1BAA circuit board assembly is part of the company’s Mark VI turbine control system. The Mark VI has been monitoring and controlling industrial turbine systems for decades. Meanwhile, Speedtronic systems have been in use since the late 1960s.

This IS200TSVOH1BAA is used as a servo valve termination board. While MKVI systems use many different termination boards, this particular board is a barrier type board that uses screws to clamp the wire connections. When connecting wires to the terminals, it is important to strip the wires to the correct length; otherwise, the screw clamps will be difficult to access.

This IS200TSVOH1BAA has two termination blocks located on one side of the board. Other connectors used on the board include d-shell connectors and vertical plugs. The board has six jumper switches that can be used to change the way a particular circuit works. Each jumper switch on the board has multiple settings. Before removing a jumper from the unit, be sure to make note of the way the jumpers were set on the previous board; best practice suggests duplicating these settings on the new assembly.

Other board components include relays, transformers, ICs, and transistors. For more information on these components and how the board should be located, wired, installed, and maintained, refer to the GE Speedtronic manual.

The IS200VSVOH1B is a VME servo control board manufactured by General Electric as part of the Mark VI series used in gas turbine control systems. The four electrohydraulic servo valves that operate the steam/fuel valves are under the direction of the servo control (VSVO) board. Typically, two servo terminal boards are used to separate these four channels (TSVO or DSVO). The valve position (LVDT) is determined using a linear variable differential transformer.

The VSVO performs a cyclic control algorithm. Three cables are connected to the VSVO at the J5 plug on the front panel and at the J3/J4 connectors on the VME rack. the JR1 connector is used for the

TSVO to provide simplex signals, while the JR1. JS1 www.cniacs.com and JT1 connectors are used to fan out TMR signals. The external trip of the protection module is inserted into JD1 or JD2.

IS200VSVOH1B Installation

Close the VME’s processor rack.

Place the board in place, then hand press the top and bottom ties into the base of the edge connector.

Tighten the plus screws at the top and bottom of the front panel.

The cable connections to the TSVO terminal board are made at the lower J3 and J4 connectors of the VME rack. They are locking the connections in order to secure the cables. Start the VME rack and check the diagnostic indicators on the front panel.

IS200VSVOH1B Operation

LVDT position feedback, LVDT excitation, bi-directional servo current outputs, and pulse rate flow inputs are contained within the four channels of the VSVO.

The TSVO can provide excitation for up to six LVDT valve position inputs, and the TSVO accepts inputs from them as well. For each servo control loop, one, two, three or four LVDTs can be selected.

For applications measuring gas turbine flow, three inputs are provided. These signals are routed through the TSVO and sent directly to J5 on the front of the VSVO board. when power is lost, each servo output has a dedicated suicide relay which, when controlled by firmware, short-circuits the VSVO output signals to common and then returns to normal operation after a manual reset command.

Each servo’s output voltage, current, and suicide relay are monitored through the diagnostic function.

Functional Description:

The IS2020JPDBG01 is a power distribution board manufactured and designed by General Electric as part of the Mark VIe series used in GE distributed control systems.

The JPDB board for AC power distribution regulates, monitors, and decentralizes AC power. The module contains two line filters and an IS200JPDB board.

The module contains two independent AC power distribution circuits, each rated at 20 A at 115 or 230 V AC.

The input circuits should be wired in parallel to prevent PPDA alarms when only one AC power source is available.

Each circuit has one fuse output and three fuse and switch branch circuit outputs. the JPDF 125 V DC power distribution module has an optional connection.

The IS200JPDB has status feedback for all fuse circuits and passive supervisory circuits for both AC ranges.

On connector P1 is the supervisory circuitry for connecting cables to the board containing the power supply diagnostic PPDA I/O packages.

Port P2 on the IS200JPDB allows monitoring signals from other power distribution system cards to pass through.

Compatibility:

The JPDE, JPDF, JPDS, and JPDM feedback signal P1 and P2 connections on the IS2020JPDB are compatible, resulting in a PPDA I/O package. The AC input on the JPDF module of the same name can be used with connector JAF2.

Installation:

In the PDM cabinet, the IS2020JPDB module is mounted vertically on a metal rear base. The protective grounding system and the IS2020JPDB sheet metal must be connected.

For the first AC circuit, input power is delivered to www.cniacs.com terminals AC1H (line) and AC1N (neutral), and for the second AC circuit, input power is delivered to AC2H (line) and AC2N (neutral).

There must be a grounded neutral connection on both AC inputs. Follow the documentation for the system’s output circuit connections.

If the distribution system has a PPDA Power Diagnostics I/O package, a 50-pin ribbon cable is required to connect JPDB connection P1 to connector P2 on the board with the PPDA. Other core PDM boards can use the P2 connector for this connection.

Operation:

The terminal block on the right side of the JPDB module has two AC power supplies connected to it. Below the IS200JPDB board, the AC power is directed to the AC line filter assembly.

The J1 connector on the JPDB circuit board is connected to the filter assembly via the wire harness.

The circuit board for the IS2020JPDBG01 module is the IS200JPDBH1A. since J1 is connected directly to the output branch circuit, this board is not used for AC power selector connections.

The IS200JPDBH2A board is used by the IS2020JPDBG02 module. This board requires an AC power selector.

The JSS1 connector is mounted on one of the boards.JSS1 receives externally filtered AC power from connector J1. To feed the power supply, the branch circuit outputs, and the source selector outputs are returned to JSS1.

The two DACA power conversion modules are powered by JAF1. which feeds power directly from input connector J1 to the adjacent optional JPDF board.

For systems utilizing 125 V DC batteries, the DACA modules are used as an AC backup power supply that converts AC power to 125 V DC power.
