TYREL PRODUCT NOTICE – GROUNDING 6/2/96

Proper grounding is critical to ensure correct

operation of your new TCX-1300 Scale Indicator.

After mounting the indicator, directly connect the power cable of the

indicator to the vehicle battery or regulated power supply.

The stand of the TCX-1300 should be connected to the vehicle frame

using a lugged 16AWG or heavier stranded wire. This lug can be connected to

one of the bolts, which secures the indicator stand to the truck if the installation allows. Alternatively this lug can be connected to one of the two #6 screws at the bottom of the stand back-plate on the backside.

NOTE: In many newer vehicles the body and cab are isolated

from the frame, making these unsuitable for ground connections.

The chassis ground from the indicator must be connected to the

frame of the vehicle to ensure proper grounding.

When using a junction box, the negative load cell excitation must

not be connected to ground In the TCX-1300 negative excitation is not the same as

frame ground… so if negative excitation shorts to frame ground, it will cause a short and the TCX-1300 will be damaged. Likely it will have a failure to show a weight. The Negative Excitation Wire is connected to position 4 of the TCX-1300’s Load-Cell Connector. Be sure the negative excitation lead and ground are separate.

NOTE: In the TCX-1300 the negative excitation is carried on the black wire. DigiStar J-box cables (and possibly other brands) have the black wire connected to the shield wire. With this type of J-box cable, the installer must make sure that the

shield wire is electrically isolated from the junction box. To isolate the shield wire form the J-box, cut it, or apply electrical tape.

If the scale head is serviced in the field, please verify that all ground connections are secured. Even verify connection of ground wires inside the TCX-1300.

Whenever Welding, Jump starting, charging or any kind of electrical work on the truck, tractor or mixer, Disconnect the power and load cell connections to the TCX-1300. Major internal damage can be caused by not disconnecting.

I. OPERATOR INSTRUCTIONS

For specific operator instructions refer to the firmware guide included with this manual, or refer to the “ON CD Manual.”

A. POWER ON SEQUENCE

When the “ON” button is pressed, the indicator will power up into either the warm up cycle or go to gross cycle depending upon how the indicator is configured. These two cycles refer to “warmup” or “GotoGr” in the configuration menu. These options are set up by the installer to comply with your local weights and measures regulations. In most applications, the indicator will be configured on the GotoGr mode. This will allow simple power on and go operation. During either power on mode, the indicator will enter the segment test.

SYSTEM WARM UP

During a warm up cycle, the upper weight display will show all eight’s and the annunciators will flash on and then off, with appropriate LED’s displaying the current configuration of the indicator (Gross or Net, Lbs. Or Kg’s etc). If the warm up cycle lasts for more than 30 minutes call your scale service dealer. Upon completion of the warm up cycle the unit will enter the segment test. The warm up cycle is designed to allow the circuits to stabilize at a working temperature. The warm up option in not necessary for normal indicator operation.

SEGMENTS TEST

During the segments test, the weight display will show all eight’s and all eight annunciators will be on. If no interaction is taken with the indicator, the gross mode will be displayed.

NOTE: If system warm up is disabled (i.e. go to gross gotogr enabled) the unit will enter the segment test at power on bypassing warm up cycle.

B. PRESSING THE ESC KEY DURING SEGMENTS TEST

By pressing esc during segments test the user will have options to change time/date, load/delivery, tolerance, print settings, remote settings and others. For more detail refer to the “TCX-1300 ON+ESC Flow chart, included with this manual, or specific sections within this manual.

C. ID/RECALL

Pressing the ID/RECALL button will usually access the Mem Card functions of the TCX 1300, some versions of Firmware do not operate this way, refer to your Firmware guide for more information. The Mem Card functions allow you to pass information to the Mem Card “Log in” and place completed feeding records into the Mem Card “LogoUt”.

SETPT/ALARM

Various versions of firmware offer options to modify Setpoint parameters, call Digi-Star’s service department at (920) 563-9700 for assistance.

E. ZERO KEY

Press the Zero key to zero an empty scale. The ZERO key will only zero the gross weight. Pressing the ZERO key while displaying NET weight will have no affect on the net or gross weights

NOTE: The Zero key can be used to zero a scale for a weight such as a container or pallet that should not be included with the item to be weighed, same applies for auto tare. NOTE: The Zero key only works when the indicator is in the gross weigh mode and the gross weight is within the zeroing range of 2% or 100% as selected by the installer, and when there is not an overload, underload, or scale in motion condition.

F. GROSS/NET KEY

Press the Gross net key during segments test to immediately enter Gross weighing mode. During normal weighing operations pressing the net/gross key will switch between the gross and net weight.

G. AUTO TARE KEY

Press the Auto Tare key to tare the scales net weight to zero. Press the Auto Tare key to tare scales net weight to zero. If the auto tare key is pressed while the 1300 is in the gross weight mode then the indicator will be placed in the net weight mode.

NOTE: The Auto Tare key will not operate with an overload, underload, scale in motion condition, or if the weight is negative.

H. UNITS KEY

Press the Units key to switch between the LB and KG weigh units. The units button will only function if the configuration step “2 Unit” has been enabled. See Operational Flowchart for more information.

I. PRINT KEY

Press the Print key to print a weigh ticket. In either the gross or net modes a weigh ticket can be printed as formatted using the “Printr” configuration. (See Firmware guide)

NOTE: The time and date will be printed if enabled. Printing is inhibited if the gross weight is negative or if o-LoAd, U-Load, no tiC, or no BAL is being displayed in the upper display. Often an o-Load or U-Load condition can be solved by Zeroing and/or auto taring the indicator. If the indicator is too sensitive to motion, the motion detection stability window can be altered. The message “no-tic” refers to no ticket present in the printer. Check the printer for problems as well, as the cabling to the indicator. If it should be required to disable the indicators ability to detect a ticket in the printer, this can be done with the buSy configuration step in the printer subsection.

J. SETPT/ALARM KEY

The set-point setup mode can only be entered from the weigh mode for which the set point is configured.

Press the set-point key to display the set-point weight settings.

NOTE: Set-Points may only be setup in the primary (LB or kg) units, but are functional in both the primary and alternate units.

If the value needs to be changed then set the new value per the following: Press the NO/CLEAR key to clear the value to zero. Press the YES/ENTER key to save the new value

NOTE: The set point responds to the absolute value of the weight reading (minus signs are disregarded). Thus, a negative weight condition may be used to activate the set point for weigh out applications.

K. ANNUNCIATORS

Eight enunciators are located to the left and right of the upper display.

ID# This annunciation is on in the id# entry/recall sequence.

MOTION when on motion is present on the scale.

LB and KG Either the LB or the kg annunciator will be on whenever the indicator is in the

one of the weigh modes.

TARE WEIGHT On in the manual tare entry mode.

GROSS WEIGHT When on the indicator is in the gross weigh mode

NET WEIGHT When on the indictor is in the net weight mode

SET PT On in the setpoint entry mode.

CENTER OF ZERO A letter “c” displayed in the top half of the most significant digit.

When on, the gross weight is within ¼ of a graduation of true zero.

L. ERROR MESSAGES

o-LoAd Whenever the weight on the scale exceeds 102.5% of the scale capacity the error message

o-LoAd will be displayed.

U-LoAd The scale may need servicing. Disconnect Load-Cell cable and press the word ZERO,

then reattach cable.

No bAL The printing was inhibited by scale motion. This message may be displayed during the

calibration procedure or during the printing process. Look at the raw counts and see if

they are varying by more than +/- 20 counts. If they are make sure the truck is not running for calibration. Check the filter settings and make adjustments if necessary.

No tiC The ticket was not printed. The ticket may not have properly placed in the printer. The

CTS line was not at the proper state to print a ticket, see section 3 for more information. Make sure the buSy= configuration step is not set to buSy=1 in the printer configuration section.

OFLO The indicator internally has gone into over range. Press the Zero button in the gross

mode and the Autotare button in the Net mode. This may correct the problem, the scale may have lost the zero point. The scale may need servicing.

UFLo The indicator internally has gone into under range. Press the Zero button in the gross

mode and the Autotare button in the Net mode. This may correct the problem, the scale may have lost the Zero point. The scale may need servicing.

NoCArd There is no MemCard in the socket or the cable to the MemCard socket is damaged or

missing. Check to see that the card is inserted correctly and nothing is blocking the pins at the bottom of the socket. Try the MemCard in the controller or another indicator. Try the MemCard socket in a different indicator. If problems persist call your local scale dealer.

LobAtt The indicator has an internal battery voltage detector. If the voltage to the indicator is

less than approximately 10.8 volts, this message will be displayed. The message will flash on the display for a period of time determined by the configuration step Lbt=***. After the time period defined by this step, the indicator will shut off. This auto-shutoff feature can be software disabled by Lbt=no

no A-d Calibration was not completed due to A/D errors. Check the internal counts.

-- SPAn Calibration was not completed due to a zero or negative span. Test weight may not be on

scale.

LoSPAn Calibration was not completed due to insufficient number of internal counts per

graduation.

F. CONTROL CODES FOR COMPUTER CONTROL

If a cable is connected to the serial port and the codes listed below are sent to the indicator, the indictor will perform the listed tasks. This can be quite useful, if programming of the indicator is to be done from a computer. All information that can be entered in from the front panel can be done through the serial port. This includes ration and feeding information. The only operation that cannot be done through the serial port is the pressing of calibration switch (SW1). This is an NTEP requirement. However, if a single raw count reading is needed while in any mode, the “T” DATA REQUEST command can be issued to get the current raw count value. This command may be issued continuously to access sequential rawcount clues. If data is to be entered for batching or feeding information (i.e. information on the 2x40 display) the same entry format for letters is required as with front panel entry. This means that to enter the letter “Q”, for example, the number 7 should be sent through the serial port followed by the down arrow twice. The information that is displayed on the upper display will be sent back through the serial port. There is no means of transmitting any of the information on the 2x40 display back through the serial port to the host computer.

The values thus selected are shown in the far right columns of this table. By far the option used most for on-board weighing is that of the Auto=3. The indicators come from the factory with an Auto=3 setting. If an individual option is to be changed, graduation size for example, do not set the indicator to Auto=3 unless all other setting are desired to be changed back to factory defaults. Use the Auto=n setting and once the chosen option has been modified, press the Yes/Enter button until the Pdn=no option is displayed. This insures that the changes have been recorded into memory.

Note: The preceding steps have been provided to adjust the indicator for the best response time

and the best vibration tolerance. The Filter Readings sets the maximum number of internal readings that may be averaged together to smooth out vibration and other scale fluctuations. The TCX 1300 takes a reading 16 times per second, thus the filter time is adjustable from .125 seconds to 2 seconds. The Filter Off Readings sets the number of consecutive readings that differ more than this amount that will be ignored; the next such reading will end filtering. The majority of applications where the scale never settles, such as a cattle scale, the High Vibration filter will need to be selected. In cases where very small changes in weight must be displayed quickly, the filter readings may be adjusted downward. In case where “spike” readings are common, the filter off readings may be adjusted upwards.

VII. CALIBRATION

A. Calibration using a Load-Cell Simulator.

REQUIRED TOOLS / ITEMS:

-Screwdriver: Medium, flat blade. (To Open/Close the TCX indicator.)

-A load-cell simulator which can achieve 0mV/V and .4mV/V settings.

1.) Turn on the indicator

2.) Open the indicator and press the tiny black push-button “SW1” one time. (Refer to page 25)

3.) Press [YES/ENTER] one time, the indicator will display “ConFig”

4.) Press [ESC] three times, the indicator will display “CAPCty”

5.) Press [YES/ENTER] one time, then use the [NO/CLEAR] key and the NUMBERS on the keypad to enter a desired Capacity.

(The TCX-1300 User Defined Capacity “CAPCty” can be set to equal the maximum amount of weight which may be loaded onto the scale system, plus the amount of weight already on the load-cells.)

For commercial applications the “CAPCty” is limited to 10,000 graduations. To calculate the capacity (in this case,) multilply 10,000 times your graduation size. Example: 10,000 * 5 = 50,000

Once the desired Capacity is visible on the indicator, press the [YES/ENTER] keypad. The indicator will display “CAL 0”

6.) (Make sure a load-cell simulator is connected to the indicator and set to 0.0

mV/V,) With “CAL 0” still being displayed, make sure the motion LED is not lit, and press the [ZERO] keypad for approximately one second. The indicator should display “CALPnt” at this time.

7.) Switch the load-cell simulator to .4 mV/V.

8.) With “CALPnt” still being displayed on the indicator, press [YES/ENTER].

Using the indicators numeric keypad, input the calibration number*. The calibration number depends on the type of load-cells in the scale system. (Call Digi-Star at 920-563-9700 to get the calibration number for your system.)

* The calibration number must be rounded to the nearest graduation. (Example: If your indicator is set to display in 5-pound graduations round your calibration number to the nearest 5.)

With the TCX Calibration Number “CALPnt” visible on the indicator, press

the [YES/ENTER] key.

The indicator will display “BUSy” for up to three minutes, then it will go into segment test (flash 888888 with all Red LED’s on.) After Segment Test the

indicator should settle into Gross Weighing Mode (The Gross LED should be on.) The amount of weight being displayed should be equal to the “CALpnt” or “Calibration Number” which was just entered.

Calibration is complete!

Switch the simulator to 0.0 mV/V, the indicator should go to 0, Press the word “ZERO” if the indicator isn’t displaying 0.

When reconnecting the load-cell cable – the weight of the “box” will appear on the indicator. The weight of the box can be “zeroed out” by pressing the ZERO key. (When the Box is “zeroed off” it will use a portion of the Indicators User Defined Capacity.)

B. Calibration using weight.

REQUIRED TOOLS / ITEMS:

-Screwdriver: Medium, flat blade. (To Open/Close the TCX indicator.)

-Calibration weight, (or a way to figure out how much weight will be loaded into the truck/wagon.)

1.) Turn on the “TCX-1000 Series” scale indicator.

2.) Make sure the “load-cell cable” is connected to the indicator.

3.) Open the TCX scale indicator and press internal push-button (SW1) one time. (A large positive number –higher than 200,000 will be displayed.)

(Refer to page 25)

4.) Press [YES / ENTER], the indicator will display “COnfig” in the upper display.

5.) Press [ESC] 3 times to “CAPCty”

6.) Press [YES / ENTER]--- make sure that the Capacity Number is correct, (change the Capacity Number if necessary.)

(The indicator’s Capacity Number can be set to the weight of the “box” plus the maximum weight that could be put into the “box”.)

(The capacity is user selectable, for more information on this please contact DigiStar.)

7.) With the Capacity Number showing on the upper display, Press [YES / ENTER] the indicator will display “CAL 0”.

8.) With the Wagon or Truck cleaned out, on a level surface, (preferably with no wind

present,) press the [ZERO] button. Now the indicator is displaying “CALPt1”

At this point some amount of weight must be put into the feed truck/wagon. It is important that this amount of weight be known or can be figured out (perhaps by using a truck platform scale.)

-If using a platform scale to figure the amount of weight to be loaded into the feed truck/wagon, then the feed truck/wagon should be weighed at this time, (this is the “empty weight”) record this number.

9.) The indicator is still displaying “CALPt1” at this time…

-If a truck scale is being used: Load some amount of weight onto the feedtruck/wagon, subtract the “empty weight” from the “loaded weight”. (At this point the amount of weight inside the feed truck/wagon has been figured.)

-If not using a truck scale: Put a known amount of weight into the truck/wagon.

10.) Press [YES / ENTER], and using the numeric key-pad enter the amount of weight

that is inside the truck/wagon. This number should be visible in the upper display.

Press [YES / ENTER], the indicator should display “BuSy” followed by

888888” then go into Gross Weighing mode.

“

The Gross Weight on the display should be equal to the calibration weight which was just put into the truck/wagon. When calibration weight is unloaded --- the indicator will display a number very close or equal to “0”.

Calibration is complete!

( Call Digi-Star’s service department at (920) 563-9700 for further assistance. )

VIII. SECURITY CODE ENTRY

The SECUrE display indicates that a password must be entered into the indicator to allow the configuration and calibration menus to be accessed. In order to proceed, you must press the Enter key to display SEC=00. Use the “?” and “?” keys to enter the first security code, then press the Enter key. The display will again show SEC=00. Now enter the second security code. After the second security code has been entered, if it matches the user defined security code, the configuration step will be displayed. Otherwise the TCX 1300 will return to a menu that is not Security protected. There is a provision to have a user definable security code in addition to the factory default. This allows the scale installer to set a code that will allow a user to access the configuration and calibration should it become necessary. This user definable access code can be changed as often as necessary with the factory default value always constant.

Test Conditions: This certificate supersedes Certificate of Conformance number 89-086A4 and is issued to indicate the transfer of ownership from Tyrel Corp. to Digi-Star LLC. The NTEP Certificate of Conformance 89-086A4, though inactive, remains in effect to cover those devices previously sold and installed under the original name. Previous test information and documentation provided by the company was reviewed. The test conditions for the original type evaluations are listed below for reference.

Certificate of Conformance No. 89-086A4: This Certificate supersedes Certificate of Conformance No. 89-086A3 and is issued to include the Model TCX-1000 and include the 12 VDC battery option. The Model TCX-1000-B was tested at –10 °C to verify operation of the LCD display at low temperatures. Additionally, low battery tests were conducted using a variable DC voltage power supply.

Certificate of Conformance No. 89-086A3: This Certificate supersedes Certificate of Conformance No. 89-086A2 and is issued to remove the B option for use of a 12 VDC power input instead of 117 VAC power. No testing was done with this power source and the B option was included in error. Test conditions for Certificate of Conformance No. 89-086A2 have been revised to remove the reference to the B option.

Certificate of Conformance No. 89-086A2: This Certificate supersedes Certificate of Conformance No. 89-086A1 and is issued to include the -L suffix. The addition of the suffix has no metrological effect on the device, and no formal testing was required.

Certificate of Conformance No. 89-086A1: This Certificate supersedes Certificate of Conformance 89086 and was issued to add optional Model TC-10A. Model TC-10A is the same as Model TC-10 except that it has extra keys on the front panel to prevent operator errors and a two digit display to show the cut-off set point. Two internal changes were made to automatically set the dead load and gain switch during calibration.

Certificate of Conformance No. 89-086: The emphasis of the evaluation was on the device design, operation, and compliance with influence factor requirements. The indicator was interfaced with an

approved weighing element for purposes of the evaluation. The indicator was tested over a temperature range of -10 to 40 °C (14 to 104 °F). Additionally, tests were conducted using power supplies of 100 to 130 VAC. The results of the referenced evaluations indicate these devices comply with applicable requirements of NIST Handbook 44.
