Chapter 3: Alarms and Error Codes

The CMZ 700 is self-diagnostic. The user manual contains a master table of LED codes and LCD messages. For example:

• Code 21 (Rotor Speed Low): Indicates a vacuum or bearing failure.
• Code 35 (Latitude Error): Input latitude likely set to zero.
• Code 44 (Power Interruption): Requires a full restart and settling.

Understanding these codes without the manual is impossible. The manual does not just list the code; it provides the course of action for each.

Manual Breakdown: What You Need to Know

If you are looking for the manual, you are likely troubleshooting or installing. Here is what the manual covers that operators find most useful:

• Latitude & Speed Error Correction: The CMZ-700 requires manual input of the ship's speed and latitude to correct for "Steaming Error" (the apparent movement of the gyro due to Earth's rotation and the ship's motion). The manual explains how to input this data. Note: Newer CMZ-700B models can accept this data automatically via NMEA from the GPS/Log, removing the need for manual entry.

• Alarm Codes: The manual provides a comprehensive list of alarm codes. Common ones include: Yokogawa Gyro Compass CMZ-700 User Manual: A Comprehensive

  • Fail 1/Fail 2: Usually indicates a power supply issue or a gyro sphere failure.
  • Temp Alarm: Issues with the cooling fluid or ambient temperature in the compass room.
  • Review Verdict: The troubleshooting section is written in "technician language." It is excellent for ETOs (Electro-Technical Officers) but can be confusing for deck officers looking for a quick fix.

• Maintenance: The manual outlines the replacement of the Gyro Sphere. This is a periodic maintenance item (usually every 2–3 years depending on running hours). The manual provides clear diagrams for removing the liquid, replacing the sphere, and re-filling the fluid mixture (specific gravity is crucial here).
