SITE PREPARATION REQUIREMENTS
Your new scale, as with any precision measuring instrument, requires an acceptable environment to operate at its peak performance and reliability. The purpose of this section is to explain how the user can provide such an environment.
Electrical Power
Most Cardinal instrumentation is designed to operate at 115 VAC, 50/60 Hz. Where required, the equipment may be ordered for operation at 230 VAC, 50/60 Hz. Refer to your order confirmation copy or to the equipment nameplate, if you are not certain for which voltage level your scale is configured.
Power Outlet
Your weighing system will require one or more power outlets. Refer to Table A to determine the number of power outlets necessary for your system. These outlets should be of the grounded, polarized type as shown above. One additional outlet is recommended to allow a source of power for test equipment to be used during installation and service.

Table A – Power Outlet Requirements
2 0330-0410-0M Rev C • Portable Digital Truck Scale
The figure to the right illustrates typical wiring from the distribution panel to the power outlets used for the weighing system.
Power outlets should be on a separate circuit from the distribution panel. This circuit should be dedicated to the exclusive use of the weighing system. The power wiring should conform to local electrical codes. Services of a qualified contractor and approval by the local building inspector generally will assure compliance with this code.
To prevent electrical noise interference, make certain that all other wall outlets for use with vacuum cleaners, lighting, industrial machinery, and other equipment are on circuits separate from that used for the weighing system.
Typical Power Outlet Wiring
AC Power Fluctuations
Your Cardinal Weighing System uses one or more microcomputer systems. Many of the problems associated with computer operations are caused by fluctuations in the AC power system. Electrical noise, power interruptions, and lightning effects from the commercial power line may enter the weighing system and cause equipment failures.
Many of the disturbances that can seriously affect the operation of a weighing system originate within the building itself. These disturbances result from switching heavily inductive loads, such as welders, motors, and solenoids. These sources of disturbances must be identified and steps taken to prevent possible adverse effects on the operation of the weighing system.
Examples of available alternatives include isolation transformers, power regulators, uninterruptible power supplies, or simple line filters.
Power Source
The power source should have sufficient capacity to supply the weighing system load.
Consideration should be given to adding extra capacity to provide for the additional loads caused by expansion of your system. Make certain this source is independent of other loads
(i.e., air conditioning and heating equipment, convenience outlets, lighting or office equipment, which can cause disturbances). A separate line back to the distribution panel usually provides suitable power. Make certain that a properly sized circuit breaker is installed in this line to safeguard against accidental short circuits.
Table B provides some basic guidelines in selection of a power-conditioning device, should it be necessary to use one. Remember that this is only a guide and that a qualified technician should be consulted for determination of the type of device suited to your application. All of the types listed are available in various sizes from Cardinal Scale or may be purchased locally.

Table B – Power Conditioning Device
Voltage
Voltage (steady state) variations shall not exceed plus (+) 10 percent or minus (-) 15 percent of the nominal value 115 VAC (plus or minus 8 percent for 230 VAC).
Transient variation (step or slope) changes of plus (+) or minus (-) 20 percent on the nominal value shall exist no longer than 0.1 second and occur no more than once every 10 seconds.
Frequency
The equipment is designed to operate at a nominal 50/60 Hertz unless specified otherwise on the equipment nameplate. The steady state harmonic distortion should be equal to, or less than, 6 percent of the fundamental frequency amplitude.
Grounding
A ground wire must be included with the power conductors (phase or L1 and neutral or L2 wires) in the run from the distribution panel to the weighing system power outlets. The size of the ground wire must comply with The National Electrical Code or local electrical code. The ground conductor must be securely bonded to the building's grounding electrode conductor.
Refer to Grounding Installation Instructions for the scale and instrument.
CAUTION!
A broken or high resistance safety ground is a potentially lethal situation. Because of line-to-chassis voltage potential, it is possible to receive a shock by touching the equipment if the green wire ground is not intact. Please be sure proper grounding is connected!
AC Neutral
The AC neutral must not be confused with protective (equipment chassis) ground. As protection for personnel, the protective equipment ground (the green wire in power line wiring) prevents the build-up of dangerous voltages on equipment. It ensures that a short circuit between L1 and the enclosure draws enough current to trip the circuit breaker immediately, rather than raising the voltage on the enclosure to a dangerous level. Do not substitute the neutral wire for the protective ground.
4 0330-0410-0M Rev C • Portable Digital Truck Scale
Safety Considerations
Safety must be a consideration in the selection of a location for your weighing system.
DO NOT locate your system in an area where flammable or explosive materials are stored or processed unless your equipment is furnished in special explosive-proof enclosures. The equipment should be placed where it does not interfere with entry to or exit from the room.
Periodic reviews should be made to make certain that the installation remains safe.
Lightning Protection
In areas subject to lightning strikes, certain steps must be taken by the customer to minimize the potential for lightning damage. These steps consist of the installation of lightning arresters as required by Article 280 of The National Electrical Code, the installation of a scale grounding system as described in Grounding Installation Instructions, and other surge arresting devices.
Heating and Cooling
Most standard Cardinal weighing system instrumentations are designed for the office environment. Such an environment is free of excessive dust and moisture and provides a comfortable temperature. In general, weighing equipment will perform well over a temperature range of 14° to 104° F. Some types of instruments and special systems will perform over a much wider range of temperatures.
In order to keep equipment cooling requirements to a minimum, the equipment should be placed out of direct sunlight and in an area where air is free to flow around all sides of the system enclosure(s). Make certain that the enclosure is not in line with a heating or cooling vent. Such a location will subject the instrument to sudden temperature excursions and may result in an unstable weight reading.
Care should be exercised by providing a relatively dust-free environment for operation of the printer. Accumulations of dust and dirt within the printer act as abrasives; also as insulators that reduce the dissipation of heat from internal components. Accumulated dust and dirt can result in premature failure.
Scale Site
The site selected for installation of the scale should provide easy access, satisfactory soil bearing capacities, adequate drainage, and be within sight of the system operator. Refer to the foundation or pit drawings furnished for soil bearing requirements.
A common source of problems is the accumulation of water under and around the scale. In spite of the best water proofing techniques, prolonged exposure to water will result in erratic weight readings and may permanently damage the scale. In areas subject to water accumulation, an inexpensive alternative is to install a sump pump to remove excess water.
Remember that power wiring for the sump pump must be contained in a conduit apart from the load cell conduit and separated from it a minimum of 24 inches.

Calibration
If, after test loading the scale, it is determined that adjustments are required, follow the procedure below. This section describes the procedure necessary to calibrate a Cardinal
Digital Truck Scale.
1.
Before any adjustments are made, turn on power to the digital weight indicator.
2.
Drive a test truck across the scale at least three times in each direction prior to calibrating the scale.
3.
Before any sealing can be done, the weight indicator must be calibrated to the scale. A division size of 10 lbs should be selected and the auto-zero function turned off. Refer to the 225 Weight Indicator Installation and Technical Manual.
All digital cells are pre-calibrated for span in the factory. That means that span calibration is not necessary to start making weights. Only a zero calibration is necessary. However, a Smart
Calibration is still usually necessary to trim the corners and sections of a scale.

DIGITAL SCALE DIAGNOSTICS
There are four main components to Digital Scale Diagnostics:
• On Screen Diagnostics – Critical errors that alert operator from main screen of setup issues or hardware problems.
• Diagnostic Menu – A set of diagnostic tools that give a technician more information about each load cell.
• iSite – Web based repository for historical load cell data that will be tracked for slow degradation of load cell integrity (for example a single load cell that is drifting away from zero). iSite will also receive all of the hardware errors found by the indicator.
• Hardware Diagnostics – LEDs on the DLC controller alert technicians of communications status.

The 225D will detect when a DLC controller or 225D mainboard has been replaced using checksums and unique board identification numbers. Based on several parameters, it can detect whether the option card was replaced or the mainboard was replaced and then reconfigure the NEW card to the existing scale.
OPTION CARD REPLACEMENT
If an option card is replaced, the 225D will boot up to this screen:
DLC
BY CARDINAL
Revision 0.1.04
NEW CARD FOUND!
WAS DIGITAL SCALE CARD REPLACED? NO
YES NO
The 225D indicator will check whether the option card has been replaced in order to reconfigure the new option card to the existing scale.
If the operator selects YES, then the 225D mainboard will upload the scale configuration to the controller, and the indicator will immediately be able to make weight again.
MAIN PCB REPLACEMENT
If a 225D main board is replaced, the 225D will boot up to this screen:
DLC
BY CARDINAL
Revision 0.1.04
NEW CARD FOUND!
WAS MAINBOARD REPLACED? NO
YES NO
The system will also check whether the 225D’s main board has been replaced, so the scale configuration can be downloaded from the controller to the main board.
If the operator selects YES, then the scale configuration will be downloaded from the controller to the mainboard. Scale configuration includes number of load cells, all load cell IDs, and individual load cell trim. Indicator parameters will need to be entered manually (Interval,
Decimal Point Position, Zero Tracking, Filtering, Print Settings, and Serial Settings).
NOTE: A dead load calibration will need to be performed (does not require test weights).

Maintenance Instructions for High Usage Weighments
1.
A High Usage Weighment Scale is one with 150 or more weighments per day.
2.
A weekly maintenance inspection should be performed.
A.
Check all load cells for and clear debris around load cells.
3.
Check beneath the bridge for debris build-up between the lower frame and the bridge.
Remove debris from each end of the scale.
4.
Test the scale with a truck carrying a typical load (i.e., a typical scale weighment).
A.
Place the truck on the scale and take a reading.
B.
Remove the truck, turn around, and re-enter the scale.
C.
The readings must repeat within ±0.2 percent of the applied load.
Example: 80,000 lb truck, the readings should be within ±8 Grads (160 lb).
5.
Structural Bridge Inspection
A.
Drive a loaded truck slowly across the scale.
B.
Observe the deck plate at the tandem axles.
C.
Excessive deflection, under the tandem axle loads, will readily reveal structural damage (i.e., a broken weld, stringer or cross member).
The above inspection procedure will require less than one hour, but will insure that the scale is well maintained and accurate. On a quarterly basis, have the scale checked with known weights (i.e., a routine scale company test).

TROUBLESHOOTING GUIDE
It can happen sometimes; the truck scale installation has been completed, but the system just doesn’t work or it has been running smoothly and then a problem occurs. Before calling
Cardinal Scale for assistance, there are a few things to check first that can be done to get the system back up and running. Remember, that there is a logical explanation for all problems and for troubleshooting to be successful, it must be approached in a logical and rational manner.
The 225D and 825D indicators used on the ARMOR Digital Truck scales are equipped with software that indicates when an error in the operation takes place. Should a problem be detected, an error message will be displayed alerting the operator to that condition. The following is a list of some of the top system problems and recommended solutions to those problems.
DISPLAYED ERROR MESSAGES
REPLACE LOAD CELL X
SOLUTION:
A. Using a NEST, test the load cell.
B. If the load cell fails the test on the NEST, replace the indicated load cell.
C. Verify calibration on the scale.
LOW VOLTAGE DETECTED CELL X
SOLUTION:
A. Using a NEST, test the load cell.
B. If the load cell fails the test on the NEST, replace the indicated load cell.
C. If the load cell passes the test on the NEST, proceed with the following:
D. Cut the end off of an extra load cell cable and strip back the wires to make a test cable.
E. Ensure the scale is powered up.
F. Remove the End Node (terminator) from the last load cell in the loop, and connect the test cable to the port on the load cell where the End Node (terminator) was.
G. Use a DVM to measure the DC voltage between the White wire (V+ Bus) and Blue wire (V- Bus). The voltage should be a minimum of 9 VDC. Note that the voltage depends on the number of load cells in loop.
H. If the system voltage is above 9 VDC, replace all the load cells indicated in the LOW
VOLTAGE error message displayed.
0330-0410-0M Rev C • Portable Digital Truck Scale 45
LOW VOLTAGE DETECTED CELL X, Cont.
SOLUTION:
I. If the system voltage is below 9 VDC, proceed as follows:
J. First remove the White (V+ Bus) and Blue (V- Bus) wires from the Homerun cable on the DLC Card, and using a DVM, read the voltage on the connector. This should be minimum of 14 VDC on the 225DLC (11.5 VDC on the 825-DLC). If the voltage is low, replace the DLC card. If it is minimum of 14 VDC on the 225DLC (or 11.5 VDC on the
825-DLC) proceed as follows:
K. Measure the current draw on the system. Remove the White (V+ Bus) wire from the
DLC card. Put one lead of a DVM in the (V+ Bus) terminal on DLC card. Attach the other lead of your DVM to the White (V+ Bus) wire going to the scale. Place your DVM in the Milliamps range. Note that on some DVM’s, you may have to move the lead position from the normal position to the 0-400 milliamps range.
L. On the 225D, you should read approximately 200 milliamps of current through an 8-load cell system (each load cell will pull approximately 25 milliamps). A 10-load cell system would read approximately 250 milliamps. Tolerance is +/- 15 milliamps.
On the 825D, you should read approximately 250 milliamps of current through an 8-load cell system (each load cell will pull approximately 30 milliamps). A 10-load cell system would read approximately 300 milliamps. Tolerance is +/- 15 milliamps.
M. If the value is out of range, disconnect all load cell cables and read the current draw with no cells connected. Now, connect the cables to the load cells one at a time, and make sure that the current draw increases each time a load cell is connected.
• On the 225D, current draw should increase approximately 21 milliamps with each load cell connected.
• On the 825D, current draw should increase approximately 25 milliamps with each load cell connected.
If you find that connecting a load cell gives you a suspect reading, try it with a different cable. If the reading is still bad, replace the load cell.
N. Proceed through testing the current draw on all cables and load cells, then retest the system voltage at the last load cell (End Node) in the loop. If the reading is still below
9 VDC replace the DLC card and check the voltage again.
O. For a large number of cells and/or a long Homerun cable, an external 24 VDC power supply may be required. Consult the factory for recommendations.
46 0330-0410-0M Rev C • Portable Digital Truck Scale
CURRENT DRAW MORE THAN 150% OF CAPACITY
SOLUTION:
A. Cut the end off of an extra load cell cable and strip back the wires to make a test cable.
B. Ensure the scale is powered up.
C. Remove the End Node (terminator) from the last load cell in the loop, and connect the test cable to the port on the load cell where the End Node (terminator) was.
D. Use a DVM to measure the DC voltage between the White wire (V+ Bus) and Blue wire (V- Bus). The voltage should be a minimum of 9 VDC. Note that the voltage depends on the number of load cells in loop.
E. If the system voltage is below 9 VDC, proceed as follows:
E. Measure the current draw on the system. Remove the White (V+ Bus) wire from the
DLC card. Put one lead of a DVM in the (V+ Bus) terminal on DLC card. Attach the other lead of your DVM to the White (V+ Bus) wire going to the scale. Place your DVM in the Milliamps range. Note that on some DVM’s, you may have to move lead position from the normal position to the 0-400 milliamps range.
F. On the 225D, you should read approximately 200 milliamps of current through an 8-load cell system (each load cell will pull approximately 25 milliamps). A 10-load cell system would read approximately 250 milliamps. Tolerance is +/- 15 milliamps.
On the 825D, you should read approximately 250 milliamps of current through an 8-load cell system (each load cell will pull approximately 30 milliamps). A 10-load cell system would read approximately 300 milliamps. Tolerance is +/- 15 milliamps.
G. If the value is out of range, disconnect all load cell cables and read the current draw with no cells connected. Now, connect the cables to the load cells one at a time, and make sure that the current draw increases each time a load cell is connected.
• On the 225D, current draw should increase approximately 21 milliamps with each load cell connected.
• On the 825D, current draw should increase approximately 25 milliamps with each load cell connected.
If you find that connecting a load cell gives you a suspect reading, try it with a different cable. If the reading is still bad, replace the load cell.
H. Proceed through testing the current draw on all cables and load cells, then retest the system voltage at the last cell (End Node) in the loop. If the reading is still below 9 VDC replace the DLC card and check the voltage again.

LOAD CELL X NOT RESPONDING
SOLUTION:
A. Jack up the weighbridge at load cell location to remove the deadload from the load cell.
B. Using a NEST, run the automated load cell test.
C. If the load cell fails the NEST test, replace the load cell.
D. If the load cell passes the NEST test, proceed to the error message,
COMMUNICATIONS ERROR BETWEEN INDICATOR AND SCALE
E. If multiple load cells are not responding, confirm that the Start Node and End Node load cells in the loop match the settings in the indicator.
COMMUNICATIONS ERROR BETWEEN INDICATOR AND SCALE
SOLUTION:
A. Remove power to the indicator, and leave it off for a few minutes. Apply power to the indicator. If the indicator displays weight, proceed with normal operations. Otherwise, follow the next steps to determine the problem.
NOTE: If the indicator works for a few minutes, then the error message appears again, install a ground wire between the 225D (825D) and the scale ground rod.
B. Go to the Load Cell Assignment screen on the indicator and write down all of the load cell IDs and their corresponding scale locations (NOT the location in the data loop).
C. If a Cardinal Digital Load Cell Simulator is available, remove the Homerun cable from the first load cell in the loop and attach it to the simulator.
D. Go to the Scale Setup screen and change the number of load cells to “1” and assign the simulator ID to that load cell position. The 225D (825D) should display
CELL RESPONDED. If NO CELL RESPONSE is displayed, return to the Calibration screen, and perform a ZERO CAL . Return to the Weight screen, and cycle power (turn off, then back on) to save the settings. The 225D (825D) should display weight when the slide on the simulator is moved.
E. If the scale will not function with the simulator, go to the Calibration screen, select
SmartCal, and attempt to calibrate the scale.
F. If the scale will not calibrate with the simulator, using a short test cable, connect the simulator directly to the 225DLC (825-DLC) card, bypassing the Homerun cable. If the
225D (825D) will not recognize and communicate with the simulator, the 225DLC
(825-DLC) card is bad and will need to be replaced.
G. If the scale will calibrate with the simulator connected directly to the 225DLC (825-DLC) card, use a NEST and perform the cable test on the Homerun cable.
48 0330-0410-0M Rev C • Portable Digital Truck Scale
COMMUNICATIONS ERROR BETWEEN INDICATOR AND SCALE, Cont.
SOLUTION:
H. If a NEST is not available, proceed with the following instructions to check the Homerun cable for shorts:
1. Disconnect the Homerun cable from the load cell (Start Node).
2. Starting with one wire, check the resistance between it and each of the other wires one at a time. With a DVM this should always read “OL” to indicate there is no current flow between that pair of wires.
3. After checking the first wire take the next wire and check it for shorts to the remaining three wires.
4. Continue this procedure until all wires are tested for shorts to all other wires.
I. If the Homerun cable, 225DLC (825-DLC) and 225D (825D) check good with the simulator, we need to test each load cell in the loop by starting with the first load cell.
Go to the Scale Setup screen, and enter “1 Loadcell” to select that cell, assign it to scale one, and enter the ID for the load cell you are connected to. Press ENTER. The
225D (825D) should display CELL RESPONDED, indicating that the load cell is communicating and good. If NO CELL RESPONSE is displayed, return to the
Calibration screen, and perform a ZERO CAL . Return to the Weight screen, and cycle power (turn off, then back on) to save the settings. If the 225D (825D) displays weight, zero the indicator, then stand on the deck over the load cell to confirm operation. If the load cell fails to respond, replace the load cell.
J. Next, connect the next load cell in the loop. Go to the Scale Setup screen, and enter
“Number of Cells 2”. Enter the ID for the second load cell. Press ENTER. The 225D
(825D) should display CELL RESPONDED, indicating that the second load cell is communicating and good. If NO CELL RESPONSE is displayed, return to the
Calibration screen, and perform a ZERO CAL . Return to the Weight screen, and cycle power (turn off, then back on) to save the settings. If the 225D (825D) displays weight, zero the indicator, then stand on the deck over the second load cell to confirm operation. If the load cell fails to respond, replace the load cell.
K. Continue adding load cells one at a time until you have a load cell that will not communicate. When that occurs, first replace the cable connecting the last good load cell to the load cell you are testing, to see if a different cable resolves the failure. If it does, proceed to the next load cell to test. If a different cable does not correct the failure, place a new load cell in the current position and input that load cell ID, and see if it responds. If the new load cell does not respond, place the new load cell in the previous position to see if it will communicate through it.
L. Continue this process until all load cells are working and making weight. After all load cells are communicating and making weight, go back into the Load Cell Setup and enter the load cell IDs in their correct scale position. Cycle power (turn off, then back on) to save the settings, perform a ZERO CAL , and then verify calibration.
0330-0410-0M Rev C • Portable Digital Truck Scale 49
LOAD CELL X HAS NO ADDRESS
SOLUTION:
A. Go to the Scale Setup screen and enter the load cell ID in the correct scale location.
COMMUNICATION ERROR BETWEEN LOADCELLS X AND Y
SOLUTION:
A. Use the NEST to test the suspect load cell cable for defects.
B. If the load cell cable tests good, use the NEST to test the two connecting load cells.
C. If a NEST is not available, replace the suspect load cell cable with a new load cell cable and confirm operation.
D. If after replacing the load cell cable, the error still exists, replace the two connecting load cells (one at a time) to confirm operation.
SCALE WILL NOT RETURN TO ZERO
SOLUTION:
A. After ensuring the scale deck is clear of any buildup or debris, enter DIAGNOSTICS.
B. The first screen displays the actual deadload that is on each load cell. If these values look correct, push the ZERO key to get a zero reading for each load cell.
C. Make multiple passes with a loaded truck and observe which (if any) load cells do not return to zero. Small errors are normal as the deck may not return to exactly its previous position.
D. If a load cell is not returning to zero, jack up the bridge at that load cell location and check for broken pivot plates, balls or the hardened cup.
E. Check for clearance from the corner stand to the main beam flanges. If a stand is not centered, and rubbing the bridge, it will cause zero errors.
SCALE IS UNSTABLE
SOLUTION:
A. Go to the second diagnostics screen MINIMUN/MAXIMUM WEIGHTS and press ZERO.
B. Observe the change in output of the load cells for 10-15 minutes to identify a drifting load cell.
50 0330-0410-0M Rev C • Portable Digital Truck Scale
LOAD CELL OR SCALE COMMUNICATIONS PROBLEMS
SOLUTION:
A. Go to the Diagnostics screen LOAD CELL COMMUNICATIONS ERRORS and observe the historical error counters for each load cell.
B. Record these numbers.
C. Press EXIT(?) to zero the counters on the 225D.
For the 825D, press C)lear to zero the counters.
NOTE: Some number of the communications errors are normal, however they should all be approximately the same.

iSITE CONFIGURATION
The 225D will periodically send indicator, scale, and cell data to the Cardinal iSite Webserver for diagnostic logging. This information will be used by the server to determine if there are problems with the scale(s) that need to be addressed.
To access the ISITE IP CONFIG menu:
1.
2.
Press SHIFT + RED_KEY to enter SETUP/REVIEW.
Press ENTER once and DOWN twice to navigate to SETUP MENU #3.
3. Select #9. ISITE IP CONFIG .
The SO# of the scale is used to match up the scale to the correct iSite dealer account. In many cases, DHCP may be used in which case setup is quite simple:
1. SO# = XXXXXX
2. DHCP = YES
If a static IP address is required (such as to address firewall issues), then set DHCP = NO and prompting will appear to manually set addresses:
1.
1.
2.
SO# = XXXXXX
2.
3.
4.
DHCP = NO
IP = XXX.XXX.XXX.XXX
SUBNET = XXX.XXX.XXX.XXX
5. GATEWAY = XXX.XXX.XXX.XXX
To confirm that iSite is working or to diagnose any errors in the connection, there is an iSite status page in the diagnostics menu. Some of the information is quite technical, but is present in case of a more complicated problem.
To check status of iSite connection:
From the main weight screen go to the diagnostics menu by pressing SHIFT +
CELL_DIAG .
Navigate with PREVIOUS/NEXT soft keys to page titled “ISITE STATUS OF LAST
CONNECTION”.
0330-0410-0M Rev C • Portable Digital Truck Scale 53
3. The following information is available:
A. IP address (if available).
B. Ethernet cable state – “ETHERNET DETECTED” or “ETHERNET NOT
DETECTED”.
C. The status of the connection. The following statuses should occur in order while making a connection after boot up: a. WAITING FOR SOCKET INIT b. IP BINDING c. DNS RESOLVING SERVER IP d. COMM ESTABLISHED – OR—PORT CONNECT FAIL
D. Once there is a connection to the web server, the previous HTTP response will be displayed: a. A good response is “HTTP RESP = 200 OKAY”. b. Any other response means there is a problem. Many issues are causes the SO# not being entered in the indicator, “HTTP RESP = 404 CHECK
SO# IN 225 SETUP”.
