• When the LED in Not Lit , that Station is not in command or
is experiencing an error.
• A Slow Blinking LED indicates that the Control Head is in
the “Warm-up Mode”.
• A LED that is Blinking Rapidly or strobing indicates that the
system is in “Troll Mode”.
E) Has anything changed on board the vessel?
• This is a question which is often overlooked but should
always be considered. Items like adding additional electronic
equipment to the vessel can obviously affect the load on the
power supply and in turn effect the Control System.
• There are also changes which may have occurred, that seem
obvious to you as having an effect on the system, that an
operator doesn’t think to tell you. An example would be re-
powering of the vessel. Changing from, lets say, a Caterpillar
to a Cummins Electronic Engine would have a serious impact
on delivering the correct signal from the Processor to the
Governor.
• Also ask about any changes, that when initially considered,
appear to have nothing to do with the Control System. An
example where this occurred was a vessel which had just
been repainted. For some unknown reason, the painter took it
upon himself to disconnect a Control Head and then recon-
nected it incorrectly.
In a lot of cases, these simple questions can resolve a problem with no
further actions from you. Take the time to consider these questions.
In the long run you will save yourself and the customer a lot of time
and money.

If a problem could not be resolved by asking the previous questions, a
careful inspection of the Control System may be the next step. Verify
