Field Installation Guidelines

• Handling Precautions: This board contains sensitive CMOS logic; use an anti-static wrist strap connected to a verified ground before removing the unit from its protective packaging.
• Backplane Alignment: Align the board precisely with the Mark V chassis rails to prevent damage to the backplane edge connector pins during installation.
• Signal Cabling: Ensure all turbine speed sensor inputs are wired using shielded, twisted-pair cabling to minimize signal noise that could cause false overspeed trips.
• Calibration: After physical installation, perform a software-level zero-speed and span calibration check through the Mark V operator interface to ensure frequency-to-RPM accuracy matches the turbine mechanical design.
