Indicates the rotor failed to reach or maintain operational speed. This could be caused by an inverter board failure, wiring issues, or a seized gyro bearing.
The CMZ 700 series is designed to withstand the harsh environments of the open sea while providing consistent heading data to various bridge systems, including RADAR, ARPA, and ECDIS. Technical Specifications and System Layout
Manages signal processing, repeater driving, and system monitoring. Operating Unit: Used for daily operation and settings. Power Unit: Provides stabilized power to the system. 3. Operating Instructions (According to the Manual)
To ensure a lifespan exceeding a decade, the CMZ-700 requires strict adherence to the maintenance schedules outlined in the user manual. Annual Maintenance Checklist yokogawa gyro compass cmz 700 user manual
: Achieves a follow-up speed of 30°/s , significantly improved from previous models to accommodate sharp-turning, high-speed vessels.
Ensure the vessel is stationary or moving at a constant speed in a straight line for the fastest settling time. Turn on the main AC/DC power switches on the Control Unit.
The most critical aspect of the user manual—and the unit itself—is the configuration for data output. The CMZ-700 is famous for its flexibility in feeding data to other navigational aids (Radars, ECDIS, Autopilots). Indicates the rotor failed to reach or maintain
This article serves as a comprehensive guide based on the (specifically the 4th edition instruction manual, IM80B10M-12E) to assist marine officers, technicians, and operators in installation, operation, and troubleshooting. 1. Overview of the CMZ 700 Series

The Yokogawa CMZ-700 series is unique due to its modular design and the use of a unique fluid-suspended gyroscope. Unlike traditional mechanical gimbals, the CMZ-700 series suspends the gyro sphere in a specialized supportive fluid, drastically reducing mechanical friction, minimizing wear, and enhancing dampening against heavy vessel vibrations and rough seas. Key Configurations Among the pantheon of navigational instruments
In the demanding world of marine navigation, precision and reliability are not optional—they are the difference between a safe voyage and a catastrophic incident. Among the pantheon of navigational instruments, the stands as a paragon of Japanese engineering, known for its exceptional accuracy, fast settling time, and robust performance in high-sea conditions.
It takes approximately 3 to 4 hours for the gyro sphere to reach its settled, true-north orientation. Do not attempt navigation or calibrate equipment during this settling window. Speed and Latitude Error Correction
Features automatic speed-error correction based on GPS latitude and ship speed signals. External Sensor Backup:
: Shows the current True Heading in a 3-digit format with a decimal point.
Usually caused by extreme weather or rapid maneuvers. The system may require a manual reset or additional settling time. Safety and Compliance
