The annunciator module is used to indicate various system events and conditions. The annunciator module uses indicator lights and an audible horn to give the operator information about the status of the system. The annunciator module can be used to announce faults and/or status signals to the operator. The annunciator module allows the operator to silence the horn. The annunciator module also allows the operator to acknowledge faults to the system.
There are 17 pairs of LED indicators on the front panel of the annunciator. The top 16 pairs of LED indicators are used to announce events, diagnostics, and ready signals. The 17th pair of LED indicators is used as a combined network/module status LED. The 17th pair of LED indicators can tell the operator if there is a problem with the RS-485 annunciator network connection.
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. The audible horn will then sound. If the low engine oil pressure shutdown is read over the data link, the annunciator will flash the red LED. The audible horn will then sound.
To acknowledge the shutdown and alarm conditions or to silence the horn, press the "Alarm Acknowledge" button (20).
To test the LED indicators or the horn when the data link is either connected or disconnected, hold the "Lamp Test" button in.
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).
For detailed information about the annunciator module, see Systems Operation, Troubleshooting, Testing, and Adjusting, UENR1210, "EMCP4.3/4.4" or Application and Installation, LEBE0007.
