INTRODUCTION
Cardinal Scale’s DC Load Cell kit provides you with the components necessary for the
construction of a digital scale for a tank/hopper installation or an above-ground or pit truck
scale. The DC Load Cell Kit utilizes Cardinal Scale’s SmartCell DC digital load cells and
225DLC or 825-DLC Digital Load Cell Controller to provide in-depth diagnostics, easy
maintenance, and a simplified calibration. Braided cabling is available for enhanced rodent
protection throughout the scale.
This manual should be studied thoroughly before attempting to install the digital scale and
must be used in conjunction with certified drawings of the particular scale being installed.
In case of conflict, the certified drawings will govern.
Safety should always be the prime consideration during all phases of the installation. Failure to
comply with the instructions in this manual will void all warranty implied or stated.

LOAD CELL INSTALLATION
NOTE: Cardinal Scale Mfg. Co. recommends that the customer install protective conduit/cover
for the load cell cables whenever the condition is present that can result in damage or abrasion
to the load cell cables.
CAUTION! Be sure all restraint systems are loosened before jacking up the scale.
1. At each section, jack up the weighbridge and remove the load cell spacers.
2. Verify that the recess in the lower Locating Plate is clean and free of dirt and debris.
3. Place the load cells in the lower Locating Plate, following these guidelines:
•Ensure the flat surface (A) of the load cell is aligned with the notch (B) in the load cell
bearing cup.
•Make sure you place the load cell bearing cup with the notch in the lower locating plate.
•Additionally, the load cell must be correctly oriented on the scale. The notch in the load
cell bearing cup must be placed in the lower locating plate in the direction of longitudinal
scale movement (with the flow of traffic).
WARNING! Failure to install the load cell correctly in the load cell bearing cup,
and the notched load cell bearing cup properly oriented in the lower locating
plate will result in damage to the load cell and void the warranty!
NOTE: The load cell bearing cups are provided with O-ring seals to ensure the cleanliness of
the bearing surfaces, and that the bearing buttons are properly centered on the bearing
surface. Should the cups become separated from the cells, first lubricate the O-ring, and then
using a small wire to break the air seal on the O-ring, press the load cell bearing button back
into the load cell bearing cup, and then remove the wire.

4. Lower the weighbridge in place and verify that the load cell bearing cup is seated on the top
plate and that the load cell is plumb (within 2 degrees in all directions).
5. When all load cells are in place, verify that the scale weighbridge is properly located
laterally and longitudinally. Verify that all load cells are vertical (plumb, within 2 degrees in
all directions). If any are not plumb, jack up the scale at that cell, and reposition the cell.
Care should be exercised to ensure that when the process is complete, all load cells are
vertical (plumb).
6. After repositioning the load cells, again verify that they are vertical (plumb, within 2 degrees
in all directions) and that the weighbridge is seated on each load cell.
7. Next, verify that each load cell is taking its share of the dead load of the scale. If necessary,
install one or more shims between the upper loading bearing cup and weighbridge.
Refer to the Balancing Weighbridge Dead Load section of this manual for instructions on
checking load cell output.
LATERAL AND LONGITUDINAL CHECKING
The check stand brackets should be set on smooth and level concrete and securely fixed to
the concrete to prevent damage to the load cells and/or the scale from excessive movement of
the scale weighbridge.
IMPORTANT! Cardinal Scale Mfg. Co. recommends that lateral and longitudinal
checking limits be adjusted to ± 1/8-inch (3.2 mm) clearance.
IMPORTANT!Load cell
must be vertical (plumb)
within 2 degrees in all
directions!

INSTALLING LOAD CELL CABLES
All digital scales using Cardinal Scale’s SmartCell DC digital load cells are connected with a
daisy-chained CAN (Controller Area Network) cable. The load cell connection loop can begin
at any load cell and may continue clockwise as shown or counter-clockwise if preferred. Note
that in the tank/hopper example below there is not a connection between cells 1 and 2 and in
the truck scale example, there is not a connection between cells 4 and 6.
NOTE: Be sure to install the End Node Terminator on the load cell at the end of the connection
loop as shown in both examples.
Example: Typical Tank/Hopper Configuration
NOTE: If the loop were run in the other direction, the sequence would then be 2-4-3-1 with
load cell 1 having the End Node Terminator installed on it.
Example: Typical Truck Scale Configuration
NOTE: If the loop were run in the other direction, the sequence would then be 6-8-7-5-3-1-2-4
with load cell 4 having the End Node Terminator installed on it.

HOMERUN CABLE INSTALLATION
The Homerun Cable is installed between the 225D or 825D indicator and the first load cell in
the loop (Start Node). Consult the chart below to determine the maximum Homerun Cable
length. Note that the number of load cells in the scale determines the maximum length.

The Homerun Cable is made from five conductors, shielded PVC cable, and is terminated in
the 225D at the P5 terminal block and in the 825D at the P1 terminal block. The load cell end
is terminated with a 5-pin spring cage connector, from the Home Run Cable Connector Pack.

2. Lift the rear panel from the main housing, taking care not to stretch the cable and wires
between the panel and main housing. Lay the rear panel on the workbench next to the
indicator.
IMPORTANT:You may need to loosen the gland connectors for the I/O cables to
allow enough slack in the cable and wires to avoid stretching them.
3. Loosen and remove the metal gland connector nut, and then remove the plastic insert.

J1, End Node Jumper
Jumper J1 is the CAN bus END NODE jumper.
NOTE: The J1 jumper must be installed for the 225D communications to the scale to operate.
J2, J3 ICAN Jumpers
When ON (installed), these jumpers allow the 225D indicator to supply (source) 15 VDC to the
digital load cells in the scale. To operate from an external power source, such as the model
MB-AC media box or an external 12 to 24 VDC power supply provided by the customer, the
jumpers must be OFF (on one pin only or removed).
IMPORTANT! To operate from an external power source, the jumpers must be OFF
(on one pin only or removed), and 12 to 24 VDC must be applied to the V+BUS
terminal with a ground return to the V-BUS terminal of the P5 terminal block.
P5, Homerun Cable
The P5 terminal block is used to connect the homerun cable between the 225D indicator and
the first load cell in the loop (Start Node in the scale). Refer to the table below for terminal

tighten each of the cable gland connectors.
2. Ensure any unused gland connectors are plugged and replace the rear panel.
3. Secure the rear panel with the fourteen acorn nuts removed earlier, following a diagonal
pattern when tightening the acorn nuts.

J2, End Node Jumper
Jumper J2 is the CAN bus END NODE jumper and should be ON (installed).
NOTE: The 825D is one end of the CAN bus connections and must be installed for the 825D
communications to the scale to operate.
J1, J3 ICAN Jumpers
When ON (installed), these jumpers allow the 825D indicator to supply (source) 12 VDC to the
digital load cells in the scale. To operate from an external power source, such as the model
MB-AC media box or an external 12 to 24 VDC power supply provided by the customer, the
jumpers must be OFF (on one pin only or removed).
IMPORTANT! To operate from an external power source, the jumpers must be OFF
(on one pin only or removed), and 12 to 24 VDC must be applied to the V+BUS
terminal with a ground return to the V-BUS terminal of the P1 terminal block.
J4, PWR END
This jumper will be installed if power originates at the 825D and powers the digital load cells in
the scale over the CAN bus cable (HomeRun Cable).
