Section 5: Troubleshooting

The user manual provides a decision tree for common alarms: PSU fuse: 5x20mm, 2A slow-blow (250V)

  1. Do not simply cut power. The gyro sphere floats on mercury. Sudden power loss without caging can cause the sphere to contact the tank walls.
  2. If the CMZ 700 has a caging switch (on older units), engage it. This mechanically locks the gyro in a stable position.
  3. Wait for the "CAGED" indicator.
  4. Then cut the main breaker.
  5. If no caging switch exists (modern units), the manual says to simply power off, but the vessel must remain upright (list less than 5°).

END OF MANUAL

Startup Sequence: Ensure the horizontal gimbal system is unlocked before switching on the main power. The system enters a "C.S." (standby) mode before reaching full operational status.
