This document provides a comprehensive list of error codes for the diesel generator controller. Each code is presented in numerical order with its corresponding parameter and description. All auxiliary output settings must be configured via a dedicated RS232 or USB communication module, and the PC must have the ComAp LiteEdit software installed to connect to the controller.
