Basic Operation
Each pair of LED indicators on the annunciator
consists of two of the following three colors: green,
yellow and red. For example, a pair of red and yellow
LED indicators may be configured for engine oil
pressure. If a low engine oil pressure warning is read
over the data link, the annunciator will flash the
yellow LED and the audible horn will sound. If the low
engine oil pressure shutdown is read over the data
link, the annunciator will flash the red LED and the
audible horn will sound.
To acknowledge the shutdown and alarm conditions
or to silence the horn, press the “Alarm
Acknowledge” button that is located near the middle
of the annunciator.
To test the LED indicators or to test the horn when
the data link is connected or the data link is
disconnected, hold in the “Lamp Test” button that is
located near the top of the annunciator.
Configuration
The annunciator module can be customized in order
to signal many different conditions that are related to
the system. Each pair of LEDs must be configured by
using the appropriate service tool. Once the service
tool has been connected to the annunciator, the user
must enter the “Configuration” screen. Each pair of
LEDs has four settings: SPN, Trigger Type, Trigger
Severity Level and Failure Mode Identifier (FMI).
