Yokogawa CMZ-700 Gyrocompass PCB
YOKOGAWA DENSHIKIKI CO., LTD.
Refurbished
The Yokogawa / YDK CMZ-700 Series is a marine gyrocompass family used onboard commercial vessels for reliable true-heading information.
This technical spare-parts reference from SM MARINE SERVICE™ focuses particularly on the internal PCB/PWB assemblies, power supply units, inverter assemblies, interface boards, terminal boards, CPU boards, display electronics, gyrosphere and other replaceable components associated with the CMZ-700 system.
A vessel does not necessarily require replacement of the complete gyrocompass when a fault occurs. In many cases, only an individual electronic board, power assembly, sensor, interface board or gyro component requires replacement.

The CMZ-700 family includes several system configurations:
Master Compass based configuration designed for appropriate vessel installations.
Master Compass combined with Control Box and additional heading/control functionality.
Dual-gyro configuration incorporating two Master Compass units with control and changeover functionality.
System configuration and installed accessories can vary according to vessel specification.
The MKM022 Master Compass is the central gyro unit of the CMZ-700 system.
Inside the MKM022 are multiple independently identifiable electronic and mechanical components.
This is important for marine engineers because many CMZ-700 faults can be traced to an individual assembly rather than the complete Master Compass.
Part / Model: KT005
The KT005 Gyrosphere is the gyro element used in applicable CMZ-700 configurations.

Different CMZ-700 documentation revisions show different inverter assembly references.
Documented references include:
V8114SW – Inverter Assembly
V8123SE – Inverter Assembly
These numbers should not automatically be treated as interchangeable.
The exact installed assembly should be identified from the existing equipment, PCB/assembly label and applicable CMZ-700 revision before replacement.
