This manual contains instructions on how to install and operate the pallet scale model ULP, designed with technology and quality standards set by Digi-Tron, a company specialized in precision instruments. Its proper functioning, however, depends also on the treatment and care given by the user, as much in the installation as in its daily use. It is, therefore, necessary to carefully read all the instructions contained in this manual, as well as abide by them. Only technicians certified by IPEM (Instituto de Pesos e Medidas/ Weights and Measures Institute) are allowed to open the instrument’s seal. The breaking of the seal by persons not certified by IPEM will result in the automatic annulment of the Digi-Tron guarantee and violates federal laws. We recommend that any technical problem be directed to Digi-Tron´s Technical Assistance Department so that we may direct you to an authorized technician. 2. Installation Your product is a mass weighing instrument and you should take certain cautions during its use. Before putting your scale to use, it is important to observe the following items:

- Verify that the instrument has not suffered any damage during delivery. - Check accessories - Take off protective insulation. (Instruments with dimensions up to

700x700mm) - Fasten the articulated feet that are in the indicator’s packaging. (Scales

800x800mm and up, follow the following instructions) - Adjust the level and then lock the articulated feet using the nuts and bolts

if the case may be. - The scale cannot undergo any kind of impact or overweighing on the

weighing platform so that there is no damage to the load receptor. Always place cargo as close to the center of the scale as possible so that there is no lateral force on the load receptors and so that you get the best weight distribution over the entire scale.

- Do not use the keypad with sharp objects in order to avoid damages to the keypad’s circuits.

- The cleaning and keeping of the entire scale will also avoid unnecessary maintenance. When possible, clean the scale with a damp cloth.

- Always clean the scale with the power cord unplugged. - Always make sure that the scale’s cables and connectors are in perfect

condition for they are essential for proper function. Maximum performance of your instrument depends on proper installation.

2.1 Accessories provided together with the scale: - Cable for battery recharge.

3. Operation The pallet scale is special by its simplicity. To transfer goods from one place to other is necessary only to put the pallet under the object in such a way that it keeps completely centralized. In this operation is necessary to use pallets to prevent damages on the forks. If the weight is not well distributed, the forks may be curved. These recommendations guarantee you the right use of the equipment improving its usage.

3.1 Special care You can see below examples of right use of the equipment:

- Never load only one of the fork pallets; - To walk up or walk down a ramp the operator must keep “holding” the

pallet scale by the loop handle always for the high part of the ramp. Right - Wrong

- Insert totally the fork pallets to maintain the equipment balanced.

3.4 Zeroing Bias in zeroing occurs due to variations in temperature, residue on the platform, impact incurred to the weighing platform, or the scale being uneven. If there is nothing on the platform and the zero indicators is off, it is necessary to zero the scale. There are two ways to do so: 3.5 Automatic Zero It is activated periodically and zeroes the reading up to + units. For example: if you have a 10kg scale with 1g divisions, this setting zeroes in the range of -3g to 3g. 3.6 Manual Zero Press Z with the platform empty to zero the scale. This setting zeroes the reading up to +20 units. After a successful weighing, the zero indicator should be lit and the display showing zero. In the case that the indicator does not light up, the weight is too heavy and is out of the automatic

zero range or the platform is oscillating. In this case press the Z button to zero the reading on the display. 3.7 Weighing without tare Before starting a simple weighing, verify these items: -The platform is empty -There are no obstructions to the weighing platform -The zero and kg indicators are lit With these items in order, you may place the product to be weighed on the scale. Avoid impacting the platform. When the cargo is on the scale and only the kg indicator is lit, it means that the cargo is stable and the reading is accurate. 3.8 Weighing with tare In this process you wish to weigh a product and subtract the weight of packaging, for example.

- Gross weight: Weight of the packaging plus the material, that is, the total weight that is on the scale.

- Net weight: is the weight that is inside the packaging. - Tara: is the weight that will be subtracted. Ex: packaging

3.9 Weight Counter

Place the weight to be subtracted on the scale and press the T button. The scale reads the tare. The display will blink in the case that the platform is oscillating or without any cargo. The tare indicator will stay lit, indicating that the scale is operating in tare mode. To exit tare mode, press the T button again. Note: The button is only accessible from the moment that the minimum weight

The sensitivity of the scale counter is 1/10, that is, one tenth of the unit division value. For example: a scale with a maximum cargo of 100kg with unit divisions of 0.01kg is capable of counting pieces weighing 0.001kg and up. To use the counter mode you need to configure the scale giving the weight and number of samples.

Set the tare with the packaging that with receive the sample. Press the T button to set the tare. Press the L button two times and the word ``tare´´ will appear on the display. Press the T button and the text will start to blink. At this time, do not touch the platform. OBS: In the case that you are not using any packaging the display will read `VAZIA´ (empty). The word PESO (weight) will appear the samples should be placed in the packaging. Press ´T`, the word will start to blink. At this time do not touch the platform. Whatever mistake will cancel the configuration (message ERRO 6/ error 6) and the procedure will have to be repeated. After reading the weight, the message qtd will appear. Press ´T´ to enter the number of samples. Note: The qtd message will only appear if the number of samples is greater than or equal to the minimum weight (20 unit divisions). For example, there are 10 pieces to be weighed. Press the ´T` button to see the cursor. Press the `L` button to change the value. Press the ´Z´ button to accept the value and start the counter.

Note 1: The more weight samples you use, the fewer the counting errors, and the closer the sample’s unit weight will be to the average weight calculated by the scale. Note 2: To be more efficient in counting, it is essential that the scale be level and away from any outside interference (air currents, vibrations, etc.).

3.10 Automatic shut-down of the display. The scale is configured to shut-down the display automatically when it’s in stand-by loaded or not. The time is 60s. In this case, the stable weight LED keeps blinking. Press the “L” button or move the scale and it will return to the weighing mode. OBS: To change the automatic shut-down time of the display it is necessary verify the menu general configurations item 4.1. 3.11 Battery Use The scale battery usage is about 50 hours. In the case of using the scale with low battery the display will show the message “LOW BAT” or “Erro 8” and the scale will shut-off automatically to prevent weighing errors. To recharge the battery is necessary to plug the cable provided with the equipment connecting it in the electrical net through the circular connector located on the side of the display. The battery charging time is approximately 8 hours.

Press the ´L`button to alternate between weight and number of pieces. Finalizing the weight counter mode To finalize the weight counter mode and return to weighing mode, press the `L´button two times.

3.12 Setting the Clock The clock displays the time that will be printed on the tickets.

Pressing the L and I buttons in sequence will access the clock configuration mode. Press Z to choose between setting the hour, date, day of the week, and year. Press T to set the clock.

Time Date Day of the Week Year

Press the T button to choose the day of the week or place the cursor on the time, date, and year adjustments.

Press the L button to change the number above the cursor on the time, date, and year adjustments. Press Z to accept the adjusted value.

The clock is powered by a long-life lithium battery when the scale is turned off. An error message is shown when the battery is low, making it necessary to change the battery and reset the clock. (see error 7) 3.13 RS 232 Serial Port The scale has a RS232 serial communication port. It is used to connect the scale to a computer or serial printer to print labels. OBS: To use the serial port is necessary to install the radio frequency communication kit – RF.

3.13.1Communication with a computer- Terminal Mode This option allows the scale to be connected to a PC so that with the use of management software it is possible to control the weighing and print reports and labels. The scale’s communication port has a configurable speed from 300 bps (bits per second) to 19200 bps. The instrument leaves the factory set at 9600 bps. A serial cable is required to connect the scale, the weight information is sent continuously. The scale continuously transmits a fixed stream of 8 bytes. The data are 8 bits in size. The stream for Modo Contadora (Counting Mode) is in the format in Figure 1.

0 primeiro byte - 0 first byte Contadora - counter Sobrecarga - excess weight Quantidade negativa - negative quantity Equilíbrio - equilibrium Centro de zero - zero center Modo tara - tare mode Quantidade (byte + significativo) - quantity (byte + significative) Quantidade (byte + signifacativo) - quantity (byte + significative) Retorno de carro - carriage return Status- status Fim de frame- end of frame Figure 1- Stream for Counter Mode

A stream for WEIGHING MODE has the format shown in Figure 2. This stream is also appears in COUNTER MODE, when the L button is pressed to alternate between quantity and weight. Peso (byte + significado)- weight (byte + significative) Figure 2- Stream for WEIGHING MODE

For example, a stream transmitted in Counter Mode is visualized in Hyper Terminal as D00005.

For example, a stream transmitted in WEIGHING MODE is visualized in Hyper Terminal as E1234.5.


11


The weight or the quantity is coded in ASC II with decimal point. The carriage return character is 0x0D (hexadecimal). The sending of the stream is interrupted in the case that there is no significance. The excess weight bit is set when there is excess weight (superior trace) or underweight (inferior traces) or analogical digital converter exceeding (Error 5). Note: For more details about configuring the serial port, check the general configurations item.

3.13.2Printing Labels The scale offers several label printing options. The serial port just needs to be configured for such (see general configurations item). There are three printer models compatible with the scales.

- Epson LX300 / LX300+ Dot Matrix Printer – Adhesive Label Printing - Epson LX300 / LX300+ Dot Matrix Printer – Adhesive Label Printing - Bematech MP20MI Dot Matrix Printer – Ticket Printing - Argox OS 214 Thermal Printer – Bar Code Label Printing

Press I to print.

The ticket will be printed as long as there is a net weight greater than or equal to the minimum weight to print (20 unit divisions) on top of the platform. If the minimum is not met, the display will blink, indicating that there is a pending printing command. If the minimum weight is met and the platform is stable, the printing will go through.

(Hold for 2s)

Ticket totals may be printed at any time. To do this, hold the I button for more than 2 seconds. It is not necessary to have any weight on the scale platform nor have it stable.


12


Observation: - To verify with what printer model your scale is compatible, check the code that appears on the display when it is turned on. - When the scale is turned on, the display will show the word `Digi-Tron´ and then the model and version code will appear. - Codes starting with the letter E indicate label printing with the Epson LX300 / LX300+. - Codes starting with the letter `t´indicate ticket printing with the Bematech MP20. - Codes starting the the letter `b´ indicate label printing with the Argox OS 214. - If the printing interface is not prompted, the communication default is with the Epson LX300 / LX300+.

3.14 Maximum Limit Retention The maximum limit retention function is used to store in the display the highest scale reading possible, that is, the maximum weight will stay frozen on the display. This function can be used for demonstrations and tests. For example: resistance tests for materials to be weighed.

Every time the limit is exceeded the scale will beep. To return to weighing mode, press the L and Z buttons in sequence again.

4. General Configurations This menu will guide you through the possible scale configurations and the necessary adjustments during the use of the instrument. These configurations are related to the instrument’s performance. We suggest that the manual be read attentively before any adjustment whatsoever. In the case that you should have a question, please contact our technical department.

Pressing the L and Z button in sequence will start the Limit Detection Mode. The Z button will restart detection.

To access General Configurations, press the L and T buttons in sequence.

4.1 Digital Filter The Digital Filter is a mechanism that adjusts platform shock absorption. At the same time, however, it adjusts the stabilizing time on the display (in other words, it slows down the scale). You should choose a filter level taking into consideration the compromise between shock absorption and weighing time. As you gain in one aspect, you loose in the other.

4.2 Reading per Second Readings per second is the number of readings presented on the display every one second interval. It also corresponds to the maximum rate by which the streams are sent by the serial communication port operating in Terminal Mode. Adjusting the number of readings per second adjusts the scale’s speed, that is, you get faster weightings. At the same time, however, it reduces the platform’s shock absorption.

5. Troubleshooting 5.1 Error Zero

- There could be weight on the platform upon turning on the scale. Take the weight off the platform.

- Moisture in the connectors. - Breakdown in the cargo cells due to overload (excess weight or impact

incurred to the weighing platform). - If the error continues, seek technical assistance.

5.2 Error Five

- Look for a bad connection in the cables or a severed cable. - Cargo cell burned by electrical surge. (solder, lightning, short circuit, etc). - In the case that there is no problem with the cargo cell, seek technical

assistance. - Breakdown in the cargo cell due to overload (excess weight or impact

incurred to the weighing platform). - In the case that the error persists, get in contact with technical assistance. - Note: In the case that error 5 is indicated, be it from impact to or overload

of the weighing platform, it is because there is a discrepancy in the cargo cell. The cargo cell will have to substitute and a new calibration will have to be done.

5.3 Error Six

Description of error: The weight is 20% heavier than the Maximum Load upon turning on the scale.

Description of error: Overload on the scale beyond the cargo cell’s capacity. This error only appears during scale operation.

Description of error: Incorrect data input.


20


- Verify that the values were entered in Counter Mode. - Verify that the values were entered within the configuration parameters. 5.4 Error 7

5.5Error Eight

- Recharge the battery. - Note: If this error appears recharge the battery immediately. Avoid

running the scale by battery. 5.6Low Battery

- Recharge the battery immediately so that there is no damage to the battery or errors in the weight readings.

5.7Overload

- Verify overload condition. The cargo cells can be damaged.

5.8Under weight.

Description of error: Insufficient operation tension to give a reliable weight reading.

Description of error: When the battery is low, this error message is shown every two minutes.

Description of error: The clock battery is low. This problem only occurs when you check the clock for the first time after turning it on.

Description of Error: The weight is over 5 unit divisions of the Maximum Load. Weight on the scale over a long period of time, can cause small deformations in the cargo cell and the loss of the initial zero reading.

Description of Error: The weight is equal to or less than -20% of the Maximum Load. Low weight cell indication, due to signal noise and traction on the contrary direction on the weight cell.


21


- Verify the spinning of the weight cell. - Verify that there aren’t any objects blocking the scale or pulling it on the contrary direction. In the case that the error persists, get in contact with Technical Assistance.

5.9Blinking Display - If the display is blinking after a command on the keypad (tare or printing),

there is a pending command waiting for the platform’s stability or the minimum weight set the tare or to print.

- If the display is blinking after starting up the scale and keeps on blinking for an extended period of time the instrument is not able to stabilize a zero reading. Check for vibrations in the platform.

- If the problem persists, seek technical assistance.

5.10 Display with some segments dimly lit

5.11 The Scale doesn’t turn on Symptom: The start-up message may light up completely but shuts down immediately or lights up and shuts down before the start-up is finished.

5.12 The scale turns off after weighing or counting

-Recharge the battery - Check to see if the Display Shut-Off Time function is activated.

Symptom: Digits or LED´s keep blinking or are dimly lit. Seek technical assistance.

If it turns on with the display brightly lit, there is too much power. Seek technical assistance. If it lights up normally but it is not able to finish the start-up, there is not enough power. Check the battery and recharge if necessary.

Symptom: The scale turns off after the start-up’s 00000.
