Menu structure
The following table provides an overview about the basic and advanced programming parameters of BLR-ACX .
Menu 100 is the Basic Menu . Menu 200 through 600 is for advanced users only and requires a PIN access (242) . The settings in these
submenus should only be accessed and changed after consulting with Eaton
