To help you get the exact technical steps or schematics you need, please let me know:
Allow the system to sit or run in a static state to let any air bubbles escape from the fluid before operational use. Gyrosphere Inspection
Measure power supply voltages to ensure they are within specification.
Periodic verification of heading accuracy and error correction, particularly in relation to speed-error correction. 4. Troubleshooting and Repair
The Anschütz Standard 20 gyro compass is a widely used marine navigation instrument offering reliable true-heading information for ships. The service manual is essential for installation, routine maintenance, troubleshooting, calibration, and repair. This article summarizes key sections and practical maintenance guidance to help ship engineers and technicians keep the unit operating accurately and safely. anschutz gyro compass standard 20 service manual
1. Check data wiring terminals for corrosion.2. Verify output signals from the Distribution Unit distribution board. 5. Technical Specifications for Service Verification
The manual serves as a comprehensive guide, containing troubleshooting aids and detailed descriptions of all electronic circuit boards (PCB) and mechanical parts. 5. Technical Specifications
Check the servo belt tension. Inspect the follow-up amplifier PCB for burnt components or loose ribbon cables. EL3: Power Supply Error
An electronic servo system that continuously realigns the outer sphere with the inner gyrosphere without physical contact, preventing frictional drag. Electronic and Distribution Units To help you get the exact technical steps
Introduced by Raytheon Anschütz (now part of Raytheon Marine GmbH), the Standard 20 series represented a leap forward in gyrocompass technology. Unlike magnetic compasses, a gyrocompass seeks true north, unaffected by the Earth’s magnetic field. The Standard 20 uses a electrically suspended gyrosphere (typically 20 cm in diameter) spinning at high revolutions—around 20,000 rpm—to achieve this.
Procedures for proper mounting and initial setup.
High-precision, with, in some cases, enhanced accuracy due to advanced speed-error correction methods. Power Requirements: Standard marine voltage inputs. 6. Safety and Environmental Regulations
– grounding, EMI suppression, emergency shutdown emergency shutdown 24V DC emergency backup
24V DC emergency backup, with 115V/230V AC mains through the power supply unit.
Always isolate the AC/DC power supply before touching the main distribution board or inverter circuits.
→ These usually require a trained Anschütz technician with calibrated test sets.
