1.11.4 SD Memory Option
An optional SD Memory card provides a medium on which to store files such as Alibi memory, IDs in the counting
application and target weights in the checkweighing application.
Note: The SD card is required for alibi memory.
The SD memory can also be used to extract and save the configuration and calibration settings of the terminal.
These can then be restored to the terminal or loaded to a different terminal. This feature can be used to clone the
setup of one terminal then transfer it to other units, which minimizes the chance of error in setting up a new
configuration.
1.12 Installation
Opening the Enclosure
The front panel of the harsh enclosure T72XW terminal is locked in place by six spring clips attached to the body of
the enclosure. To access the terminal’s PCB to install options, connect internal wiring and set switches, separate
the front panel from the enclosure as follows:
1. Insert the tip of a flat-blade screwdriver into one of the two slots located on the bottom of the front panel assembly
(see Figure 1-2). While squeezing the front panel and enclosure together, gently push the screwdriver in toward
the enclosure. A “pop” sound is made when the cover clip is released.
Figure 1-2: Opening the Harsh Enclosure
2. Repeat Step 1 for the other slot.
3. After releasing the two clips securing the bottom of the front panel, move the panel to each side to disengage
the side clips, then lift the bottom of the front panel firmly up and out (Figure 1-, 1) until it completely clears the
top edge of the bottom enclosure.
4. Squeeze the top of the front panel to the enclosure along the top edge slightly and push upward (Figure 1-, 2)
to unsnap the top two clips, then lift the cover to clear the two top clips. The cover will swing down, hinged by
two wire cables at the bottom.

Installing Cables and Connectors
Information for installing cables and connectors for the T72XW terminal is provided in this section, including:
Ferrite Core
Main Board Wiring Connections
Wiring Connections for Options
Ferrite Core
In order to meet certain electrical noise emission limits and to protect the T72XW from external influences, it is
necessary to install a ferrite core on the load cell cable connected to the terminal. The ferrite core is included with
the basic terminal.
To install the ferrite, simply route the cable through the center of the core and then take one wrap around the
outside of the core and route the cable through the center again. Either the complete cable or the individual wires
can be wrapped through the ferrite. This should be done as close to the enclosure as possible. See Figure 1-.
Figure 1-4: Installing the Ferrite Core
Main Board Wiring Connections
Once the T72XW terminal harsh enclosure is open, connections can be made to the terminal strips on the main
board, as shown in Figure 1-.

Load cell connections are made to the load cell connector located on the main board as shown in Figure
1-.
The AC version of the T72XW terminal is designed to power up to ten 350-ohm load cells (or a minimum resistance
of approximately 35 ohms). The battery version of the T72XW terminal is designed to power up to four 350-ohm
load cells (or a minimum resistance of approximately 87 ohms). To confirm that the load cell load for this installation
is within limits, the total scale resistance (TSR) must be calculated. To calculate TSR:
TSR =
Load Cell Input Resistance (Ohms)
Number of Load Cells
Ensure that the TSR of the load cell network to be connected to the T72XW has a resistance greater than the
minimums listed above before connecting the load cells. If the resistance is below the minimum, the T72XW will not
operate properly.
In addition, the maximum cable distance must be reviewed. Table 1-4 provides recommended maximum cable
lengths based on TSR and cable gauge.

When both SW1-2 and SW1-4 are positioned ON and AC power is applied to the terminal, a Master Reset function
will be initiated. This procedure will erase all programming in the terminal and return all settings back to factory
default values. This process is described in the T72XW Technical Manual, Chapter 4, Service and Maintenance.
SD Card Installation
The SD memory card can be used for additional storage in the Checkweighing and Counting applications, and
must be installed if the Vehicle Application is used. Figure 1-6 shows the installation of an SD card into the socket
on the edge of the T72XW main board.
Figure 1-6: Sliding an SD Card into the SD Socket (left); SD Card Installed (right)
Capacity Label Instructions
The regulations in some locations require that the scale capacity and increment be shown on the front of the
terminal, near the display. To satisfy this requirement, a blue capacity label is included with the terminal that must
be completed and adhered to the front overlay.
The capacity label (shown in
Figure 1-7) provides space for the Max, min, and e information for both ranges for which the scale is programmed.
If only one range is used, the unused portion of the label may be cut off with scissors. Written information must be
legible and a minimum of 2mm or 0.08 in. in height. A permanent marker should be used for this information.
Figure 1-7: Preparing the Capacity Label

7000 SERIES INDICATORS EN 11
Clean any oil or other contaminants from the area of the overlay shown in Figure 1-8 where the capacity label will
be added. Peel the backing from the label and adhere it to the overlay in the location shown in Figure 1-8, or
another location acceptable to the local regulations.
Figure 1-8: Capacity Label Installed
Closing the Enclosure
After all work has been completed inside the terminal, the enclosure must be snapped shut properly to maintain its
environmental integrity.
To properly close the terminal, follow these steps:
1. Position the front cover over the rear housing then gently press it down into place.
2. Press down firmly in each of the four corners of the front cover in sequence until each corner clip snaps audibly
snaps into place.
3. It is very important that each of the 4 corner clips have snapped into place. When pressing down on the cover
during installation, listen for the “click” sound of each clip engaging.
Securing the Enclosure
When the T72XW terminal is used in a metrologically “approved” application, it must be protected from tampering
by use of a seal. A wire security seal is included with the terminal.
For sealing details of the T72XW terminal, refer to Figure 1-9 and follow these steps:
1. Ensure that the appropriate approval region has been selected in setup under Scale > Type > Approval, and
that the Metrology security switch SW1-1 is in its ON position (refer to Figure 1-5 and
2.
3. Table 1-5).
4. With the front panel installed on the enclosure and snapped into place, thread the free end of the wire seal
through either the left or right hole in the T72XW front panel, and through the hole in the retaining clip.
5. Thread the end of the wire cable through the hole in the plastic seal (as shown in Figure 1-9), remove any
remaining slack in the wire, and snap the seal shut.

1.13 Display and Keyboard
The T72XW terminal uses a graphic, transflective type Liquid Crystal Display (LCD) with a white LED backlight.
The front panel including the display and keypad is shown in Figure 1-.
Figure 1-6: T72XW Front Panel Layout
1.13.1 Display Layout
At the top of the display, a single system line displays terminal status and operator error displays and messages.
Time and date and the status of the Digital I/O can be displayed in this area, when so configured in setup.
Below the system line is the weight display. During normal, basic weighing operation, the T72XW terminal display
shows the Gross or Net weight in the larger 28.5mm (1.1 in.) size. When one of the applications is running, the
weight is shown in 20mm (0.8 in.) high characters. Below the weight display is a single line to display the weight
units, the weight legend, the center of zero icon, weight range and motion icon. Tare values also appear on this
line, to the left of the display.
At the bottom of the normal basic weighing display is a line used for data entry. For display operation during setup,
refer to Chapter 3, Configuration.
1.13.2 Front Panel Keys
The T72XW terminal provides a total of 25 keys as an operator interfaces. The ON/OFF key, four scale function
keys and three operational keys are positioned under the display while the alpha-numeric keys are positioned to
the right of the display. The print/enter key and navigation keys are located at the bottom right of the display. These
keys are used to enter the setup menu, to navigate and select setup elements, and to enter values in setup as
described in Chapter 3, Configuration.

2.2.2 Keypad Operation
The front panel keys are used to operate and configure the T72XW.
Alphanumeric Keypad
The T72XW permits the entry of both alphabetical and numeric data, using the 12-element keypad to the right of
the display.
Figure 2-2: Alphanumeric Keypad
Key Timeout Period
When using the keys to enter data, after a set amount of time elapses the terminal accepts the character that is
currently displayed, and moves to the next position. Pressing the key without allowing the Key Timeout period to
elapse cycles through the current option for that key. For instance, when the 4 key is pressed in mode, the
display cycles through g, h and i.
The length of this timeout period is measured in tenths of a second, and can be configured in setup at Terminal >
Terminal\Device.
SHIFT Key
The SHIFT key is used to determine the type of entry made when a key is pressed. Four entry modes are
available:
Numerical (123)
Upper case alphabetical (ABC)
Lower case alphabetical (abc).
Decimal entry (Dec) (This mode is available only when entering template strings.)
The current entry mode is indicated at the upper right corner of the display (Figure 2-, Table 2-1).
Entering Numeric Data
To enter a number into either the ID (data) field in the main display, or into a field in one of the setup screens:
1. Check that the entry type display shows 123; if it does not, press the SHIFT key until 123 appears.
2. Then simply press the appropriate keys on the key pad –0 to 9 and period.
Pressing a numeric key followed by TARE enters a manual tare value. Pressing the ID key shifts
focus to the prompt line at the bottom left of the screen, and allows data entry there.
To delete one or more figures, press the CLEAR key.
Entering Alphanumeric Data
To enter an alphabetic character:
1. Press the SHIFT key to access the character type (lower or upper case)
2. Press the appropriate key until the correct character displays.
For example, when the display is in its default (numeric, 123) entry mode, the key sequence to enter The T72XW
(including a space) is shown in Table 2-2.
