The ACS 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.
