3.3 BMS II MENU STRUCTURE
The BMS II incorporates an extensive menu structure which permits the operator to set up, and configure
the unit. The menu structure consists of nine major menu categories as shown in Figure 3-2. Each of the
menus shown, contain options which permit operating parameters to be viewed or changed. The menus
are protected by two different password levels to prevent unauthorized use. These passwords provide
access as follows:
• Password Level 1 (159) allows viewing of all menu categories. In addition, this Password Level allows
all Menu options to be changed, except for Calibration Menu options.
• Password Level 2 (6817) allows viewing and changing of the options contained in the Calibration
Menu. In addition, it allows all Level 1 menu categories to be viewed or changed. The Calibration
Menu should only be used by factory-trained personnel.
Prior to entering the correct password, the options contained in all of the Menu categories (except the
Calibration Menu) can be viewed. However, except for Internal Setpoint Temperature (Field Adjust Menu),
none of the viewable menu options can be changed.
Once the valid Level 1 (159) or Level 2 (6817) password is entered, the options listed in the available
menus can be viewed and changed, if desired.
Menu Processing Procedure
Accessing each menu and option is accomplished using the Menu Keys shown in Figure 3-1. Therefore,
