Functional Description

• The IS215VPROH2BD manages emergency overspeed protection in the Mark VI system.
• It operates with TPRO and TREG terminal boards to create a robust safety mechanism.
• Triple redundant VPRO boards sit in a dedicated module separate from the control system.
• These boards control trip solenoids through the TREG board for reliable shutdown action.
• An Ethernet connection supports IONet communications with control modules.
• The VPRO board executes the emergency trip function inside Protection Module P.
• It connects up to three trip solenoids to TREG and TRPG terminal boards.
• The TREG board supplies the positive side of 125 V DC to the solenoids.
• The TRPG board provides the negative side for the same solenoids.
• Either board can initiate a turbine trip for redundancy and fail-safe operation.
• The board also oversees emergency stop functions beyond overspeed protection.
• It controls twelve relays on the TREG, with nine relays in three groups of three.
• These groups act as voting inputs that influence the three trip solenoids.
• The VPRO can drive a secondary TREG board through J4 for extra backup.

Input and Output Features

• Inputs: Passive speed pickups, generator and bus voltage, thermocouples, 4-20 mA current or voltage signals.
• Inputs: Trip interlocks and emergency stop functions for comprehensive monitoring.
• Outputs: Trip solenoids and economizer relays for protective actions.
• Outputs: Breaker relay commands and servo clamp relay contacts for precise control.
• MPU Characteristics: Specific output resistance and inductance values ensure efficient signal transmission.
• MPU Cable Requirements: Maximum distance of 300 m (984 ft) with shielded pair cables.
• Signal Integrity: Specific capacitance and resistance values support reliable data acquisition.

Installation Guide

• Power down the VME I/O processor rack before you begin the installation.
• Insert the VPRO board into the designated slot with both hands.
• Gently push the top and bottom levers to seat the edge connectors.
• Tighten the captive screws at the top and bottom of the front panel.
• Power up the VME rack after the board sits securely in place.
• Check the diagnostic lights at the top of the front panel.
• Verify proper initialization and functionality before you continue.
• Use J3, J4, J5, and J6 connectors on the front panel for cable connections.
• These latching connectors link to TPRO and TREG terminal boards.
• Connector J7 accepts the 125 V DC power input.
• Update the firmware to the latest version for optimal performance.
