Viewing Active Faults and Warnings
You can view active faults and warnings from the Faults and Warnings Menu.
Warning messages indicate a problem that could affect normal operation.
“Warning Active” appears on the LCD to notify you of the warning condition.
Normal operation continues until the warning condition:
•
clears and normal operation continues
•
escalates to a fault condition.
Fault messages indicate a fault condition. When a fault occurs, the XW SCC:
•
displays “Fault Active” on the LCD
•
disables the MPPT and charging functions
•
opens the relay that connects its power circuits to the battery bank.
The only fault that does not disable normal XW SCC operation is the Auxiliary
Output Overload Fault. The Auxiliary Output Overload Fault only disables the
auxiliary output. Other XW SCC functions continue operating. The Ground Fault
disables the auxiliary output as well as normal XW SCC operation.
Most warnings and faults clear automatically once the condition that caused them
goes away. The only exceptions are the Auxiliary Output Overload Fault and the
Ground Fault. The Auxiliary Output Overload Fault must be cleared manually.
The Ground Fault requires you to correct the ground fault and restart the system.
For more information, see Troubleshooting.
To view the complete list of active faults and warnings:
1. Press Enter on the Active Faults and Warning Menu screen.
2. Press the down button to view additional fault or warning messages.
If there are no active faults and warnings, no messages are displayed after you
press Enter from the Active Faults and Warnings screen.
To manually clear a fault:
1. Identify the active fault from the Active Faults and Warning Menu.
The two faults you can manually clear are “Batt Under Volt” (except when the
battery voltage has fallen below 10 V) and “Aux Output Ovld.” and See Table
4-6 for descriptions of these faults.
2. Press Exit to return to the Active Faults and Warnings Menu, then press the
down arrow to view the Clear Fault screen.
“Batt Under Volt” is displayed first.
3. Press Enter to view the cursor.
4. Press Enter again to clear the “Batt Under Volt” fault.
Or
Note:
The Faults and Warnings menu is visible only when the XW SCC has one or
more active faults or warnings.
