Appendix A - System Parameters

The following system parameter groups are listed as they appear on the Edit Parameters (EP) menu. See Section 4.0, User Interface, for information on using the EP command on the Supervisory Menu.
These parameters are for reference only and are not intended to be a comprehensive listing as the APU software is constantly evolving. Through periodic reviews and updates, we endeavor to keep it as current as possible. For parameters not found in this text, refer to the on-board help within the EP application (<CRTL>-U) or to the revision text file “VERSION.TXT” on the APU. Parameters from this text but not on your APU are not available to the current version of software in the APU.
