The key to troubleshooting the CruiseCommand Control System is
identifying which of the categories listed below is the cause of the
problem:
• DC Power Source
• Interconnecting Wiring (Harnesses)
• Engine or Transmission
• Component Calibration
• Control Head Failure
• Processor Failure
The following pages should give you a good guideline for making this
determination. There is no need to troubleshoot the system to any
point further than one of the main components listed above. If the
fault is found to be with a Control System component, that component
is simply replaced.
In the event of a system malfunction, the first thing which typically
comes to the attention of the operator is the vessel’s current situation.
Are there other vessels in the area, is the vessel pulling to the Port or
Starboard, etc.? The second item which will draw the attention of the
operator is the Control Head and it’s levers. For this reason, and the
fact that the Control Head is located where the operator is, the Control
Head is utilized as the starting point for troubleshooting system mal-
functions. The Control Head produces 5 different tones to warn the
operator of a potential problem. These tones are explained in full
detail in Section 1.5. Additionally, the Red LED’s status; for instance,
are they On, Off, Blinking, etc.?
Knowing the status of these items is
quite beneficial in the troubleshooting process.
The Control Heads, located at all remote stations, have LED’s (Light
Emitting Diodes) and Sound Transducers installed. These devices
provide visual and audible system status indication, which assists in
system troubleshooting.
