IS220PSVOH1A - SERVO PACK

Functional Description

IS220PSVOH1A is a Servo Control Pack under the Mark VIe series. GE developed this component for its Mark VI or Mark VIe systems. Steam and gas turbine systems are controlled by both of these systems.

1. The IS220PSVOH1A is an electrical interface that connects a TSVO servo terminal board to one or two I/O Ethernet networks. The WSVO servo driver module is used by the IS220PSVOH1A to control two servo valve position loops.

2. A front faceplate with various LED indications is included with the PSVO. Four LEDs display the state of the two Ethernet networks (ENet1/Enet2), as well as a Power and Attn LED and two ENA1/2 LEDs. There's also a single infrared port on the front, but it's not used in this pack.

3. After installation, the Control System Toolbox application is used to setup the IS220PSVOH1A. A CPU board with input power connectors, local power supply, and an internal temperature sensor are included in the kit. The board also has flash memory and RAM. This board is linked to a purchase board.

4. When the IS220PSVOH1A is replaced, it can be auto-reconfigured. This feature can be activated or disabled in the ToolboxST application's Component Editor. The operator can also manually reconfigure the module using the Component Editor.

5. The I/O pack must be manually reconfigured when a terminal board is changed. Stroking the actuator in manual mode, position ramping, or step current can all be used to test servo performance. Any irregularities in the actuator stroke will be displayed on the trend recorder.

6. Manufacturer user guides and manuals might provide more information about this and other parts of the board, their installation and operation, as well as any potential compatibility difficulties.
