Visual and Audio Warning Systems
Audio Warning System
IMPORTANT: The audio warning system alerts the operator that a problem has occurred. It does not protect the engine from
damage.
Most faults cause the warning horn circuit to activate. How the warning horn activates depends on the severity of the problem.
There are two warning horn states:
• Caution
• Critical
There is also an alarm that sounds if the helm has not been properly configured using the G3 service tool.
Caution
If a caution state is detected, the audio warning system will sound for six one‑second intervals.
a - Horn (on or off)
b - Time (in seconds)
Critical
If a critical state is detected, the audio warning system sounds for six seconds and then turns off.
a - Horn (on or off)
b - Time (in seconds)
Nonconfigured Alarm–DTS Only
If the helm has not been properly configured using the G3 service tool, the audio warning system will sound for five one‑second
intervals.
