Frequently Asked Questions (FAQ)

What is the main purpose of this module?

• The IS220PPROS1B provides independent backup overspeed protection and generator synchronization checking for turbine systems.

How many packs are typically used in a system?

• A typical TMR system uses three PPRO packs mounted to a simplex protection (SPRO) terminal board.

What trip boards are compatible?

• Compatible with TREG (gas turbine), TREL (large steam), TRES (small steam), and TREA emergency trip boards.

How does it monitor primary control?

• It acts as an independent watchdog, monitoring primary control performance and validating speed operations.

What configuration software is required?

• Configuration is performed using the ToolboxST* application software from General Electric.

What happens during a fault detection?

• When a fault is detected, it trips the backup trip relays on the trip board and initiates a trip on the primary control system.
