Type "E" codes - Indicate an external fault condition has occurred and caused charging to stop.
Type "P" code - Indicates charger programming mode is active. This will occur when the charger profile is
being configured.
Type "USB" code - Indicates the USB interface is active, and the USB should not be removed. This will
occur when the charger firmware is being updated.
Solid red - Internal fault condition. Type "F" fault code.
Flashing amber - External fault condition. Type "E" error code.
Flashing green - USB interface is active.
Solid green - Firmware update is complete. Remove USB from charger.
Codes are displayed as F, E or P and followed by three numbers and a period (example: E-0-0-4). The
charger can display multiple codes.
If the batteries are changed from one type to another, (example: flooded lead acid to AGM), the charger
profile must be programmed. Refer to Repair Procedure, Programming the Charger Profile.
