Annunciator Module

Illustration 5	g01101388

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 current 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 seventeen pair of LED indicators on the annunciator's front panel. Sixteen pair of LED indicators are used to announce events, diagnostics, and ready signals. The seventeenth pair of LED indicators is used as a combined network and a module test. The seventeenth pair of LED indicators can tell the operator if there is a problem with the J1939 data link 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 reading is read over the data link, the annunciator will flash the yellow LED and the audible horn will sound. If the low 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 when the data link is disconnected, hold in the "Lamp Test" button that is located near the top of the annunciator.

The annunciator module can be customized in order to signal many different conditions that are related to the system. Each pair of LED lights 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 LED lights 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, RENR7902, " 3508B, 3512B, 3516 and 3516B Engines EMCP3".
