Navigation Keys

AC Overview (2) - The "AC OVERVIEW" key will navigate the display to the first screen of AC information. The "AC OVERVIEW" information contains various AC parameters that summarize the electrical operation of the generator set.

Engine Overview (3) - The "ENGINE OVERVIEW" key will navigate the display to the first screen of engine information. The "ENGINE OVERVIEW" information contains various engine parameters that summarize the operation of the generator set.

Main Menu Key (4) - The "MAIN MENU"key will navigate the display to the main menu directly without having to navigate out of menus.

Acknowledge Key (5) - Pressing the "ACKNOWLEDGE" key will cause the horn relay to turn off. This will silence the horn. Pressing this key will also cause any red or yellow flashing lights to either turn off or to come on continuously, depending on the active status of the alarms. The "ACKNOWLEDGE" key may also be configured to send out a global alarm silence signal on the J1939 Data Link, which will silence the horns on the annunciators.

Reset Key (6) - Pressing the "RESET" key will reset various events.

Event Log Key (7) - Pressing the "EVENT LOG" key will navigate the display to the event log.

RUN Key (8) - Pressing the "RUN" key will start the engine.

Escape Key (11) - The "ESCAPE" key is used to navigate through the menus. When the key is pressed, the user moves backward or the user moves upward through the menus. The "ESCAPE" key is also used to exit out of entering data when the user is programming the setpoints. If the "ESCAPE" key is pressed while the user is programming the setpoints, none of the changes made on the screen will be saved to memory.

Up Key (12) - The "UP" key is used to navigate through the various menus and monitoring screens. The "UP" key is also used when a setpoint is entered. When entering numeric data, the "UP" key is used to increment the digits (0-9). If the setpoint requires selection from a list, the "UP" key is used to navigate UP through the list.

Right Key (13) - The "RIGHT" key is used during setpoint adjustment. The "RIGHT" key is used to select which digit is edited while entering numeric data. The "RIGHT" key is also used during some setpoint adjustments to select or to unselect a check box. If a check box has a check mark, the function has been enabled. Pressing the "RIGHT" key will disable the function. Pressing the "RIGHT" key will also cause the check mark to disappear. If the check box does not have a check mark, the function is disabled. Pressing the "RIGHT" key will enable the function. Pressing the "RIGHT" key will also cause a check mark to appear.

Enter Key (14) - The "ENTER" key is used to navigate through the menus. When the key is pressed, the user moves forward or the user moves downward through the menus. The "ENTER" key is also used to save any changes while the setpoints are being programmed. Pressing the "OK" key during programming the setpoints causes the changes to be saved to memory.

Down Key (15) - The "DOWN" key is used to navigate downward through the various menus or screens. The "DOWN" key is also used to program the setpoints. The "DOWN" key is used to decrease the digits when entering numeric data. If the setpoint requires selection from a list, the "DOWN" key is used to navigate DOWN through the list.

Left Key (16) - The "LEFT" key is used during setpoint adjustment. The "LEFT" key is used to select the digit that is edited during the entry of numeric data. The "LEFT" key is also used during some of the setpoint adjustments to select a check box. The key is also used to unselect a check box. If a check box has a check mark, pressing the "LEFT" key will disable the function. Pressing the key will also remove the check mark. Pressing the "LEFT" key will also cause the check mark to disappear. If the check box does not have a check mark, pressing the "LEFT" key will enable the function. Pressing the "LEFT" key will also cause a check mark to appear.

Solar Battery Charging System



Illustration 3g06243110
(1) Solar array panel

Solar Array Panel - One solar array panel is on the roof of the power module (1).

Check wire connections for tightness and corrosion, and exposed areas for chaffing and wear regularly. Module surface may be cleaned as needed using a soap and water. Abrasive chemicals cannot be used in the cleaning of your solar module. As the combination of water and electricity produces a large shock hazard, disconnect your solar panel from the charge controller or battery prior to any cleaning process and always wear protective rubber gloves and rubber sole shoes when working with electricity.

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 that 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.
