Description
Product Overview
The Kongsberg PSI-100 3C is a marine-certified signal conversion board designed for Dynamic Positioning (DP) systems. It converts analog synchro, resolver, or stepper signals from vessel gyrocompasses into high-resolution digital data. This ensures low-latency, real-time heading telemetry directly to the central DP controller for precise station-keeping.

Operational Guidelines
Power-Up / Power-Down Sequence
- Startup: Isolate the rack power. Slide the card into its slot until fully seated, then secure the screws. Restore rack power. The green heartbeat LED will flash steadily, confirming a successful boot and backplane handshake.
- Shutdown: Deselect the gyro channel on the DP operator terminal. Turn off the rack power breaker. Wait for power to discharge, then use the ejector handles to remove the card using proper ESD protection.
Step-by-Step Standard Operation
- Set Voltage: Adjust onboard switches to match the gyro stator voltage (11.8V to 90V).
- Mount Card: Insert the board into the marine cabinet slot using an anti-static wrist strap.
- Verify Lock: Power up and check that the front LEDs show a solid signal lock with the gyro.
- Calibrate: Cross-check the digital heading on the DP screen with the mechanical gyro compass.
- Engage Loop: Activate the heading channel in the DP software matrix for active vessel control.
Frequently Asked Questions
Q: What does a red front-panel LED mean? A: It indicates a reference signal mismatch or a loss of incoming synchro phases. Check the field wiring and gyro output fuses.
Q: Can I hot-swap this card during live DP operations? A: No. Removing an active sensor card disrupts the positioning algorithm and can cause sudden thruster movement. Always take the channel offline first.
Q: Are different part numbers like 37752771 and 37737996 interchangeable? A: Yes, these are production revisions of the same core PSI-100 3C framework and share identical backplane pin assignments.
