Installation/Operation Manual - Introduction 3
Front Panel
The 920i front panel, shown in Figure 1-1, consists of a 27-button keypad with a large backlit LCD display. The
keys are grouped as five configurable softkeys, five primary scale function keys, four navigation keys, and
numeric entry keys.
Two scale widgets can be displayed in standard metered water applications. Status areas on the display are used
for operator prompts and entering data. Display contrast can be adjusted with the LCD contrast potentiometer.

1.1 Operating Modes
The 920i in the CB-2 automated concrete batching
system has two basic modes of operation:
Normal mode
Normal mode is the weighing mode of the
indicator. The CB-2 “program” only executes in
Normal Mode. The weight is only displayed in
Normal Mode. Once configuration is complete
and a legal seal is affixed to the large fillister-head
screw on the indicator enclosure, this is the only
mode in which the
920i
can operate.
When in Normal Mode, the CB-2 program will
always show softkeys. The operator’s interaction
will be driven by softkey selections. As softkeys
are collectively named in the Main Menu. On the
far right of the main menu is the “Admin Menu”
softkey. The Admin Menu may be passcode
protected. The Admin Menu is where all
configuration and database entry takes place. A
large portion of this manual is dedicated to
explaining the categories and individual settings
in the Admin Menu.
Setup mode
A few of the procedures described in this manual
require the indicator to be in setup mode,
including configuration and calibration.
Setup Mode (sometimes referred to as
Configuration Mode) is entered by pressing the
setup switch. Setup Mode will be used during the
initial installation of the CB-2. Calibration of the
scales, configuration of filtering and motion band,
and upgrading the CB-2 software are some of the
important tasks that require the indicator to be in
Setup Mode. Once the CB-2 has been installed
and calibrated, there will probably be only three
reasons to ever enter Setup Mode again;
•
Annual service calibration of scales
• Adding a PS/2 keyboard
• Upgrading the CB-2 software
Section 3 of this manual explains the Scale
configuration and calibration while in Setup
Mode.
To enter setup mode, remove the large fillister
head screw from the enclosure. Insert a
screwdriver or a similar tool into the access hole
and press the setup switch once. The indicator
display changes to show scale configuration
menus.
