FCC NOTE
This equipment has been tested and found to comply with the limits for a Class A digital device, pursuant
to Subpart J of Part 15 of the FCC Rules. These limits are designed to provide reasonable protection
against harmful interference when the equipment is operated in a commercial environment. This
equi pment generates, uses and can radiate radio frequency energy and, if not installed and used in
accordance with the instructions manual, may cause harmful interference to radio com munications.
Operation of this equipment in a residential area is likely to cause harmful interference in which case the
user will be required to corre ct the interference at his/her own ex pense.

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 -500 indic ators have been designed to operate from 4- AA alkaline /rechargeable batteries and
ships with an AC adapter designed to operate from the local line voltage. The un it ship s 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.
CONNECTI ONS

CALIBRATION
CALIBRATION OVERVIEW
If your indicator was shipped as a co mplete 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, y ou should record all calibration values in Table 2 using the F18 View Calibration
proc e dure.
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 "
mome n tarily, and then revert back up to F16. At this time, proceed to the F17 span calibration
to complete ind i cator 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, and then revert back up
to F17. .
5. At this time it is suggested that the calibration values be recorded for future use (see next
s ection).

10
If the calibration was not successful, one of the error messages below will appear. Take the
ind icated 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 capa c ity
of the scale. Change the calibration test weigh t or check the input data.
" Err2 " – There is not enough 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)
No te: 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.

The Continuous Dup lex Mode (A3 = ‘C’, A6 = ‘0’) 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 r e quiring 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.
R ECOGNIZED 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 mo tion, 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, positi ve 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 e stablished.
“C” - This command is sent to the indicator to toggle among the configured units of measure.

APPENDIX C : DISPLAYED ERROR CODES
CODE MODE MEANING / POSSIBLE SOLUTION
No rmal Operating
Mode Gross Overload. A weight greater than the rated capacity has been applied to the scale. Remove the weight from the platter or try re-calibrating the
scale. Otherwise, check for a bad load cell connection or possible load cell
damage due to overloa d ing.
Err 0
Span Calibration
Mode (F17)
Keyed -in weight value is larger than full-scale capacity. Use a smaller test
weight or check keyed - in value.
Err 1
Span Calibration
Mode (F17)
Keyed -in weight value is less than 1% of full-scale capacity. Use a larger
test weight or check keyed - in value.
Err 2
Span Calibration
Mode (F17) There is not enough load cell signal to produce the internal counts necessary to properly calibrate the scale. First check all load connections.
Use F16 mode to view int ernal counts.
Err 3
All Modes Non -volatile memory read error. One or more setup parameters have been
lost.
Err 4
All Modes Non - volatile memory write error. Indicator needs service.
Err 9
Normal Operating
Mode
Span calibration value has been lost. Re - ca librate the scale.
