INSTALLATION
PREPARATION
Any precision instrument requires a suitable environment in which to operate as intended. Please review
each of the following prior to installation:
Electrical Power
The TI-500E Plus indicator has been designed to operate from 9 to 12 VDC and ships with an AC
adapter designed to operate from the local line voltage. All units ship with the appropriate power plug for
its area of intended use.
To avoid electrical noise interference and/or stray AC electrical transients, try to operate the indicator
from a circuit separate from any equipment containing inductive devices such as a contactor coil,
solenoid, relay coil, or motor. Be sure to use shielded cables for the load cell connections (ground shield
wire at indicator) and run these cables away from your AC/DC power cables if possible.
In extreme cases, it may be necessary to install surge suppressors, line conditioners or even UPS
(Uninterruptible Power Supplies) systems (not included).
Environment
-
Avoid installing the indicator in areas of direct sunlight or high humidity
Avoid sudden temperature change – if this is unavoidable allow equipment to ‘soak’ at a constant
temperature for at least three hours before use
Ensure that steady, clean AC power is available to the unit
Remember that the installer is ultimately responsible to assure that a particular
installation will be and remain safe and operable under the specific conditions
encountered.
CONNECTIONS
The rear panel contains all connectors necessary to make the appropriate connections to the weigh
platform, printer, remote display and power supply.
2
CONNECTING THE WEIGH PLATFORM
The TI-500E Plus ships with a 15 ft shielded load cell cable for connection to weigh platform’s load cell(s)
or junction box.
1. Plug the cable’s 14-pin parallel interface connector into the load cell port on the rear
panel of the indicator.
2. Wire the bare wires and shield to the weigh platform’s load cell(s) or junction box using
the color codes shown below.

CONNECTING THE POWER SUPPLY
The TI-500E Plus indicator ships standard with an external AC adapter.
1. Simply plug the AC adapter into the indicator’s DC Power Jack first, and then plug
into a standard wall outlet. Make sure that the AC voltage appearing at the wall
outlet matches the input voltage marked on the AC adapter.

CALIBRATION
CALIBRATION OVERVIEW
If your indicator was shipped as a complete scale, then calibration is not necessary. Please check
with your installer or supplier if you are unsure. Transcell recommends having your weighing
equipment checked by a qualified scale technician at least once a year depending on its intended
use and working environment.
The indicator requires two types of calibration: zero and span. Zero calibration (F16) requires the scale to
be empty (nothing on scale) and the span calibration (F17) requires known test weights. After a
successful calibration, you should record all calibration values in Table 2 using the F18 View Calibration
procedure.
In the unlikely event that any calibration value is lost, the setup menu makes provisions for re-entering
these values via F19 and F20; thus eliminating the need for re-calibration with test weights.
NOTE: This section assumes that the indicator is in Setup (“F”) Menu mode. If the indicator is not in
Setup Menu mode, refer to previous section for instructions.
ZERO CALIBRATION (F16)
1. While in the Setup mode, scroll to "F 16", then scroll down once using the ZERO key to enter
zero calibration menu. The display will momentarily show "C 0" followed by a value. This value
is the internal A/D count and can prove useful when trying to troubleshoot setup problems.
2. After making sure that there are no test weights on the platform, press the ZERO key again to
zero out the displayed value.
3. Press the NET/GROSS key to save the zero point value. The display will show "EndC0"
momentarily, and then revert back up to F16. At this time, proceed to the F17 span calibration
to complete indicator calibration.
SPAN CALIBRATION (F17)
1. While in the Setup mode, scroll to "F 17", then scroll down once using the ZERO key to enter
span calibration menu. The display will momentarily show "C 1" for the first span calibration
point, followed by a value with one flashing digit. This value will be zero with the Decimal Point
parameter selected in F10.
2. Place the first test weight on the weighing mechanism.
3. Use the four directional keys to adjust the displayed value to the actual test weight value.
Increase the flashing digit by pressing the UNITS key. Decrease the flashing digit by pressing
the ZERO key. Pressing the PRINT key or the TARE key will change the position of the
flashing digit.
4. After entering the exact value, press the NET/GROSS key to save the value. If the C1
calibration was successful, the display will show "EndC1" momentarily, followed by
"C 2" for the second calibration point.
5. Repeat steps 2 thru 4 for C2 and C3. At the conclusion of C3, the indicator reverts back up to
F17. NOTE: If you wish to use only one calibration point (C1), simply press the NET/GROSS
key when prompted for C2 and C3 (do not enter in a calibration value).
10
6. At this time it is suggested that the calibration values be recorded for future use (see next
section).
If the calibration was not successful, one of the error messages below will appear. Take the
indicated action to correct the problem, and then perform a new calibration.
"Err0" - The calibration test weight or the keyed-in weight is larger than the full capacity of the
scale. Change the calibration test weight or check the input data.
"Err1" - The calibration test weight or the keyed-in weight is smaller than 1% of the full
capacity of the scale. Change the calibration test weight or check the input data.
"Err2" – There is not enough input signal from the load cells to establish a proper calibration.
Most commons causes include incorrect load cell wiring, a mechanical obstruction or a faulty
load cell.
VIEW CALIBRATION VALUES (F18)
Note: The values displayed in this procedure are valid only after a successful calibration has been
performed using F16 and F17.
1. While in the Setup mode, scroll to "F 18", then scroll down once using the ZERO key to enter
View calibration menu.
2. The display will show the information listed in Table 2. The code will display briefly followed by
the value. It is recommended that you record each value in the table below. Press any key to
continue down the list. At the completion of the list, the indicator reverts back up to F18.

KEY-IN ZERO CALIBRATION VALUE (F19)
Note: This procedure is intended for emergency use only in the case of non-volatile memory loss.
A valid zero calibration value, obtained from a successful F16 calibration procedure, must
be used.
1. While in the Setup mode, scroll to "F 19", and then scroll down once using the ZERO key. The
display will momentarily show "ET C 0", followed by a value of zero
2. Use the four directional keys to enter in the actual zero calibration value.
3. After entering the exact value, press the NET/GROSS key to save the value. The display will
show "E E C 0" momentarily, and then revert back up to F19.
KEY-IN SPAN CALIBRATION VALUE (F20)
Note: This procedure is intended for emergency use only in the case of non-volatile memory loss.
Valid span calibration values, obtained from a successful F17 calibration procedure, must
be used.
1. While in the Setup mode, scroll to "F 20", and then scroll down once using the ZERO key. The
indicator will prompt you to enter the information in Table 3.
2. If the value shown is correct, press the NET/GROSS key to move to the next parameter.
Otherwise, use the four directional keys to enter in the actual calibration value
3. After setting the exact value, press the NET/GROSS key to save the value.
4. If the entered values are entered successfully, the display will show "E" momentarily before
continuing to the next parameter. At the completion of the sequence, the indicator will then
revert back up to F20.

FUNCTION KEYS
Units – This key toggles the indicator among the available weight units if enabled in the User (“A”)
menu. Available weight units include lb, kg and pieces.
Zero - This key sets the indicator to display zero provided the following conditions are met:
1. The indicator is displaying Gross weight.
2. The displayed weight is within the zero reset range that is programmed in F4 of the Setup (“F”)
Menu.
3. The scale is not in motion.
4. The scale is not in overload (see Appendix D for error codes).
Net/Gross - This key toggles the indicator between Gross weight and Net weight only if a Tare has
been established.
Tare - This key is used to establish a Tare provided the following conditions are met:
1. The indicator is not at or below Gross zero.
2. The scale is not in motion.
3. The scale is not in overload (see Appendix D for error codes).
Print - This key is used to send weight information out to the serial port provided the following
conditions are met:
1. The scale is not in motion.
2. The scale is not in overload (see Appendix D for error codes).
GENERAL SCALE OPERATION
WEIGHING AN ITEM
1.
Select the desired weighing unit by pressing the lb/kg key until that unit is indicated on the
display.
2.
If necessary, press the ZERO key to obtain a weight reading of zero.
3.
If weighing an item in a container, place the empty container on the scale’s platter and, after
allowing the weight indication to stabilize, press the TARE key. The display shows zero weight
and turns the NET annunciator on
4.
Place the object to be weighed on the scale’s platter and allow the weight indication to
stabilize. If the item weight exceeds the scale’s weight capacity, it displays “oooooo”.
5.
Read the weight shown on the display. If you have established a tare, you may toggle between
the gross weight and the net weight by pressing the NET/GROSS key
14
PIECE COUNTING MODE
IMPORTANT NOTE: The piece counting function cannot be used in commercial (NTEP)
applications.
To activate this mode, set F30 to 3. This mode is used to indicate the number of pieces of an item
you have placed on the scale’s platform and is accessed by pressing the UNITS key. To ensure
accuracy, the parts you are counting must be consistent in weight.
The indicator uses the sampling method to determine the average piece weight (APW) of the items
you wish to count. When sampling items, always count the parts in your hand and place them on
the platform all at once. If the APW of the items is too light or the total weight of the sample is too
light, accuracy cannot be guaranteed. You will get an error message, but piece counting will still be
allowed. This indicator does not retain the piece weight when powered down.
1. If the items you will be counting require a container, you must first tare the container off by
pressing the TARE key.
NOTE: The TARE key is inoperative when in sampling mode.
2. Press the UNITS key until “5 0” is indicated on the display. If the screen does not show “5 0”,
press the ZERO key once. The indicator is prompting you to place five identical items on the
platform.
NOTE: If you wish to change the sample number, simply press the UNITS key repeatedly until
the desired sample number appears. Available choices are 5, 10, 20, 50 and 100. If you
continue to push the UNITS key, the indicator will resort back to weighing mode and you must
start again from Step 2.
3. Place the sample items on the platform all at once and allow the weight indication to stabilize.
Once this is done, the zero indicated after the sample number will change to a “–“. For example,
“5 –“.
4. Press the NET/GROSS key to take the sample. If the sample size is large enough, the indicator
now displays the number of pieces on the platform and the “PCS” annunciator is lit. If not, the
indicator briefly displays “Lo” and automatically increments the sample size. Repeat Step #4
with the new sample size.
NOTE: If the indicator continues to display “Lo” even after sampling 100 pieces, the unit weight
of the items you wish to count is too light for your scale to process accurately.
5. To exit the piece count mode, press the UNITS key.
NOTE: The APW will NOT remain in scale memory when you exit piece counting mode.
PEAK HOLD MODE
IMPORTANT NOTE: The peak hold function cannot be used in commercial (NTEP) applications.
To activate this mode, set F30 to 5. This mode is used to indicate and hold the peak weight
recorded during a specific process. The most common application is testing the breaking point of a
part or assembly. The TI-500E Plus records both positive and negative peak weights.
1. Push the UNITS key to active peak hold mode; the display briefly shows “HOLD”. If the display
does not show 0, then press the ZERO key.
2. Apply force to the piece – the display indicates and holds the peak force applied.
3. To toggle between positive and negative peak weights, use the NET/GROSS key.
4. To reset both peak values to zero, press the ZERO key.
5. To exit peak hold mode, press the UNITS key again; the display briefly shows “-HOLD”.
15
REMOTE DISPLAY MODE
To activate this mode, set F30 to 2. This mode is used to emulate a remote display for a separate
indicator. For it to work properly, a remote indicator must be transmitting information to the TI-500E
Plus continuously and at the same transmission (baud) rate configured in A1.
LEGAL FOR TRADE SEALING
Indicators can be sealed for commercial (Legal for Trade) applications as follows.
1. Power off the indicator.
2. On the back of the indicator, locate the setup/calibration switch cover.
3. Thread a wire security seal through both drilled head screws securing the calibration switch cover
as well as the single drilled head screw holding on the rear panel.

APPENDIX B: SERIAL PORT INFORMATION
SERIAL PORT MODES
DEMAND DUPLEX MODE
The Demand Duplex Mode provides a two way serial transmission mode. In this mode, the output
information is transmitted on demand; either by pressing the PRINT key on the indicator’s front panel
or upon receiving a recognized command from a host device (i.e. computer).
NOTE: Ensure that your cabling contains the proper handshaking.
CONTINUOUS DUPLEX MODE
The Continuous Duplex Mode provides a two-way serial transmission mode. In this mode, the output
information is transmitted continuously making it a popular choice for remote displays and other
remote devices requiring a constant data stream. The transmission automatically occurs at the end
of each display update. The indicator will react upon receiving a recognized command from a host
device.
RECOGNIZED HOST COMMANDS (applies to both demand and continuous duplex modes)
“P” - This command is sent to the indicator to print the indicated display. The indicator will not
respond if the scale is in motion, positive overload or negative overload.
“Z” - This command is sent to the indicator to zero the scale. The indicator will not respond if the
scale is in motion, positive overload or negative overload. The indicator will also not respond if
it is not in gross mode or within the zero range specified in F4 of the Setup Menu.
“T” - This command is sent to the indicator to tare the scale. The indicator will not respond if the
scale is in motion, positive overload or negative overload. The indicator will also not respond if
it displaying a negative gross value.
“G” - This command is sent to the indicator to switch to gross mode. The indicator will not respond if
the scale is in motion, positive overload or negative overload.
“N” - This command is sent to the indicator to revert to net. The indicator will not respond if the scale
is in motion, positive overload or negative overload. The indicator will also not respond if a tare
has yet to be established.
“C” - This command is sent to the indicator to toggle among the configured units of measure.
AUTO PRINT MODE
The Auto Print Mode provides a one-time serial transmission once a non-zero, stable condition is
achieved.
TEST AND MEASUREMENT MODE
The Test and Measurement Mode is identical to the Demand Duplex Mode with one exception: the
indicator will respond to a PRINT command even if the scale is in motion, positive overload or
negative overload.
