Chapter 2 Scale Operation
The GuardianXL has many advanced features. This Chapter will describe how to operate
an installed and functioning GuardianXL indicator.
Front Panel Features
The GuardianXL is equipped with a 19 pushbutton keypad. The layout is shown in
Figure 2.1 below. The GuardianXL display is divided into five areas.
Figure 2.1 GuardianXL Front Panel Layout
Primary LED Display
The primary display consists of six bright, 1” high, seven-segment red LED digits. These
digits typically display the current weight and are visible up to 50 feet away.
Secondary LCD Display
The two line 32-digit alphanumeric backlit LCD display provides feedback to the user.
This display is primarily used for displaying the gross / net mode, center of zero status,
motion, displayed units, setup mode and calibration mode information.

Scale Mode Control and Navigation Pushbuttons
The blue pushbuttons on the left of the touch panel controls the displayed units, gross /
net mode, tare, print and programmable pushbuttons. These pushbuttons also navigate
through the setup and calibration modes.
Numeric Keypad and Configuration Shortcut Pushbuttons
The purple numeric keypad is used to enter data for tares, setpoints and setup
configuration. The setup and calibration mode is entered through shortcut pushbuttons
that have setup and calibration menu abbreviations below the numbers on the keypad.
These dual function shortcut pushbuttons provide quick access to specific parameters in
the setup and calibration modes.
Scale Zero Pushbutton
This is the most often used feature of the indicator. Therefore the ZERO pushbutton is
centered on the front panel and the largest pushbutton on the GuardianXL.
Modes of Operation
Weighing Mode
The weighing mode of the GuardianXL is the most commonly used mode. While in this
mode, the primary display will indicate current weight and the secondary display will
indicate gross / net, center of zero, motion and displayed weight units. The rest of this
Chapter describes this mode in detail.
Output Mode
The output mode is only active while the GuardianXL is in the weighing mode and when
any output is enabled. The second line of the secondary display will indicate the status of
each setpoint output while the indicator displays all weigh information included in the
weighing mode. A sample output status line is “1- 2- 3- 4*” where a dash to the right of
the output number indicates an inactive output while an asterisk to the right of the output
number indicates an active output. Outputs are accessible at terminal block TB3 or by
the Digital I/O option. Setpoint configuration is described in Chapter 6.
Batch Mode
The batch mode controls outputs in a batch sequence. Batch sequences require no
programming to implement, simply select a canned batch sequence from the menu and
the program is ready to run. The second line of the secondary display will indicate the
status of each setpoint output while the indicator displays all weigh information included
in the weighing mode. A sample output status line is “1- 2- 3- 4*” where a dash to the
right of the output number indicates an inactive output while an asterisk to the right of the
output number indicates an active output. If a standard batch sequence does not meet
your needs, the batch sequence can be altered by changing setpoint configurations. The
batch mode is fully described in Chapter 7.
