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. Sixteen 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 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 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.
The annunciator module can be customized 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".

Controller - The solar battery charging controller is located inside the upper generator terminal box.
During normal operation, the "charging" LED should always be ON solid during sunlight to indicate the solar array is contributing power to the controller. Also, the "battery status" green LED (one on the left) should either be ON solid (indicating batteries fully charged) or blinking (solar is charging) and the other two "battery status" LEDs (yellow and red) should remain off.
Battery type selection for XQ product is number 2 (Sealed). Temperature sensor for batteries is not used on XQ product.
Battery Connection - Battery "+/-" has an uninterrupted connection to the batteries. A two-pin connector is located near the batteries to allow isolation from the solar charging system if desired. If the connector is unplugged, the red "battery status" LED will be "ON" solid.
The unit is equipped with display interface that provides touch screen control, and data logging. The display interface also provides the following capabilities:
- Fuel level monitoring
- Diesel Exhaust Fluid (DEF) level monitoring
- High Exhaust System Temperature (HEST) indicator
- Diesel Particulate Filter (DPF) indicator
