INSTALLATION & OVERVIEW

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.
The indicator must be properly configured and calibrated prior to use.
Installation
Find a suitable location for the indicator and use the included bracket to mount the unit to a wall or table. Use this handy guide for mounting the bracket to a wall or table: The indicator ships with a homerun cable which plugs into the appropriate connector. Use the following color codes to connect the load cell or junction box.
Load cell / junction box Cable Leads

The indicator features one full duplex RS-232 serial (COM) port, designed for connection to a computer or a serial printer. The same port may be also used as a simplex, RS-232 port de-signed for connection to a remote display.
DSUB9 Connector

The indicator has been designed to operate from 9 to 12 VDC and ships with an AC wall adapt-er designed to operate from the local line voltage. All units ship with the appropriate power plug for its area of intended use.

Getting Started

1. There is a power switch on the rear panel of the unit. Flip the switch to the “1” position to switch on.

After a brief initialization period, the indicator will revert to a zero (“0”) weight display.
Your indicator is now ready for configuration and calibration.

INDICATOR CONFIGURATION

Configuration Menus
The TI-500E contains two (2) menus to configure the indicator:
Setup (“F”) Menu – Configures all metrologically-related parameters including calibration procedures.
User (“A”) Menu – Configures communication parameters and other misc. parameters, e.g., Units key behavior.
The configuration menus are laid out in the following vertical arrangement:

•  Top [Parameter] level
•  Selection level (or function level, e.g., span calibration)

Please review the following chart to get a feel for how to navigate among the various menus and parameters. Entering the Setup (“F”) Configuration Menu

1. Switch off the indicator
2. Locate the slide switch on the rear cover and move it to the opposite position. NOTE: A metal plate held on by two drilled-head screws conceals the slide switch.
3.  Switch on the indicator. The display shows “F 1” to indicate that you are in Setup Menu mode.
4. Move from one “F” menu parameter to the next by using the TARE (left) or PRINT (right) keys. For example, to go from F1 to F2, press the PRINT key. To go from F2 back to F1, press the TARE key.
5.  Once you have arrived at the proper “F” menu parameter, e.g.,” F 1”, press the ZERO (down) key once to arrive at the selection level. The indicator displays the current parameter setting.
6. If there is a selection list, scroll thru the available parameter settings, use the TARE (left) or PRINT (right) keys. Otherwise, use the arrow keys to adjust the displayed value to the new value.
7. Once the setting you want is displayed on the screen, press the NET/GROSS (set) key to save this value.

INDICATOR CALIBRATION

Calibration Overview

There are two ways to calibrate the instrument:

1. Live calibration: You will be calibrating a scale platform to the indicator using actual loads, e.g., test weights. In general, this is the most accurate and dependable method of the two.
2. mV/V calibration: You will be calibrating the instrument using a load cell simulator (calibrator). You must calculate what weight value corresponds to a specific mV/V setting on the calibrator. (Hint: use the rated output of the load cell.)

For both methods, the calibration procedure comprises two steps: zero calibration (F16) and span calibration (F17). We recommend doing zero calibration (F16) first.

Only one span calibration point is supported on this model. This span calibration point is denoted as C1. The minimum load that can be used for C1 is 1% of Max (maximum capacity). The recommended load is 2/3 of Max, however 100% of Max can also be used. In general, the larger (heavier) the calibration weight, the more accurate the scale will be after calibration.   The procedures that follow are written for “live” calibration mode. When using a calibrator, simp-ly substitute the mV/V setting for the prompted load (weight) values.

Zero Calibration Instructions (F16)

1. While in the Setup mode, scroll to “F 16”, and then scroll down once using the ZERO (down) key. 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. Assure a no-load condition on the scale platform and then press the ZERO key again to zero the display reading. Do NOT skip this step!
3. Press the NET/GROSS (set) key to save the zero-point value. The display will show “SET” and “EndC0” momentarily, and then revert up to F16.

Span Calibration Instructions (F17)

1.  While in the Setup mode, scroll to “F 17”, and then scroll down once using the ZERO (down) key. The indicator will briefly display ‘C 1’ and then prompt you to enter the data for the span calibration point (C1).
2. Place the actual calibration load (weights) onto the scale platform.
3.  Use the four directional keys to enter in the actual calibration weight value, e.g., 5000 lb. Increase the flashing digit by pressing the UNITS key. Decrease the flashing digit by pressing the ZERO key. Pressing the TARE key or the PRINT key will change the position of the flashing digit.
4.  Press the NET/GROSS (set) key to save this value. The indicator briefly displays ‘End C1’, and then reverts up to the F17 screen.

If the calibration was not successful, one of the following error messages will appear.

• “Err0” – The calibration test load or the keyed-in load is larger than the full capacity of the indicator. Change the calibration test load or check the input data.
•  “Err1” – The calibration test load or the keyed-in load is smaller than 1% of the full ca-pacity of the indicator. Change the calibration test load or check the input data.
•  “Err2” – There is not enough “signal” from the scale platform to complete the calibration process. Most common causes include incorrect weight sensor wiring, a mechanical obstruction or a faulty (damaged) load cell.

Take the indicated action to correct the problem, and then perform a new calibration.
Exit calibration mode by moving the slide switch back to its original position. The display will go through a digit check, and then settle into Normal Operating mode. All front panel keys will now return to their normal mode of operation.

ADVANCED OPERATION

Piece Counting Mode
This mode is used to calculate (“count”) the number of items (parts) you have placed onto the scale platform. To ensure accuracy, the items you wish to count must be consistent in weight. To activate this mode, set F24 to “1” in the Setup Menu. The indicator uses the sampling 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 is too light or the weight of the sample size is too light, accuracy cannot be guaranteed. You will see an error message, but piece counting will still be allowed. This indicator does not retain the piece weight when powered off.

1. If the items you will be counting require a container, you must first tare off the weight of the container by pressing the TARE key.
2. Press the UNITS key a few times 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 onto the scale platform4.
3. Place the samples onto the platform all at once and allow the weight indication to stabi-lize. The screen will change from “5 0” to “5 – “.
4.  Press the NET/GROSS key to take the sample. The indicator now displays the number of pieces on the platform and the “PCS” annunciator is lit5.
5.  To exit the piece count mode, press the UNITS key. The APW will NOT remain in scale memory when you exit piece counting mode.

Please refer to the footnotes below in case of errors and then take the indicated actions to cor-rect the problem.

•  If you wish to change the sample size, simply press the UNITS key a few times until the desired sample size appears. (Available choices are 5, 10, 20, 50 and 100). If you continue to press the UNITS key, the indicator will resort back to weighing mode and you must start again from Step 2.
• If the sampling process was not successful, the indicator briefly displays “Lo” and automatically increments the sample size. Repeat Steps 3 and 4 with the new sample size. If the indicator continues to display “Lo” even after sampling 100 pieces, then the unit weight of the items you wish to count is too light fo your scale to process accurately.

SERIAL (COM) 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 or upon receiving a recognized command from a host.
NOTE:
Ensure that your cabling has a crossover (null modem) and contains the proper handshaking lines.
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 trans-mission automatically occurs at the end of each display update.
RECOGNIZED HOST COMMANDS

Please note that host commands may be ignored if the scale is in motion, in positive overload or in negative overload.
AUTO PRINT MODE
The Auto Print Mode provides a one-time serial transmission once a non-zero, stable condition has been achieved.
Note:
this option may not be available on all models
