3.13 BMS II QUICK-START GUIDE
NOTE
The “Quick Start” procedures in paragraph 3.13 assume that the
user fully understands the BMS II menu structure and is able to
navigate through these menus to display and change menu
options. Refer to paragraph 3.3 for menus and menu processing
procedures.
The following procedure assumes that you are programming a new BMS II that has the “Factory Default”
settings currently stored in memory.
If you wish to restore a “Field-Programmed” BMS II to the “Factory Default” values, go to the
CALIBRATION MENU and select the RESET DEFAULTS option. ALL SETTINGS, EXCEPT TIME AND
DATE, WILL RETURN TO THEIR FACTOR DEFAULTS.
This paragraph provides the instructions to quickly start up and operate the BMS II in some of the most
