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

D3556 05/29/03 REV. 2.2 Copyright 2001 2

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 [phone] 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.

D3556 05/29/03 REV. 2.2 Copyright 2001 8

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

D3556 05/29/03 REV. 2.2 Copyright 2001 9

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.

Hi CAP Calibration was not completed due to lack of over-capacity span. The TCX 1300 must be

able to display 104% of the capacity.
