DISPLAY AND KEY DESCRIPTION

OPERATING INSTRUCTIONS

Power On
Turn on the power by pressing the power button for 2 seconds. Once on, the scale will flash the voltage and then begin to auto-check and count down from 0-9 sequentially before entering the weighing modeNote: Anything on the scale before powering on will automatically be tared out.

Zeroing

• The zero function is used only when the scale is empty and is not at gross zero due to material build-up
• Pressing the ZERO key will reset your scale to 0
• Depending on what your manual zero range parameter is set to, you can zero out any numbers within your set selection, after that you will receive an error and will need to tare out the weight

Unit Selection
To switch between measuring units ((kg/g/lb/oz/lb:oz) press the UNITS key

Tare Function

• The Tare function is used when you only wish to see the current change in weight, not the entire amount of weight that is on the scale.
• When the indicator is in gross mode (gross light is shown) pressing the TARE keywill Tare the current weight on the scale and enter the net mode (net light shown).
• For example, if you are using a container add the container to the scale, press tare and the display will show the tare symbol and reset back to 0.
• Add your product to the scale to weigh without the weight of the container.
• To exit Tare mode press the TARE key again to enter gross mode and you will see the total weight of the container and the product
• Note: If you remove the container the scale will show the minus weight of the container

To use a pre-set tare weight

• Press and hold the TARE key for 2 seconds.
• Input the tare weight using the arrow keys.
• Press print key to confirm

Counting Function

• The counting function is used to count a high volume of identical parts. You can do this by setting a sample and then either adding to the sample or taking away from the sample to count the number of objects on the scale
• In weighing mode: Put a sample weight on the scale (Sample options are 5, 10, 20, 50, 100, 200, 500)
• Then press the COUNT key to go to the counting mode (“pcs” will light up)
  ● It will then display the sample number (ex. ) which you can change using the up or down arrows
  ● Press the PRINT key to confirm your sample number
  ● The scale is now ready to start counting, load your product on the scale and the indicator will show the quantity
  ● To exit counting mode press the COUNT key
  ● If you want to count a different product hold the PRINT and COUNT key together and the sample pieces will reset back to zero

Accumulation

• The accumulation function is used to add multiple weights and total them together
• In weighing mode load the first weight, once stable press the ACCUM key to enter the accumulation mode. The “total” indicator/light will display
• The screen will show “ ” to indicate the first weight has been saved
• Remove the first weight and press the ZERO key to stabilize the scale
• Add the second weight to the scale
• Once stable press the ACCUM key to add the weight to the accumulated total
• The screen will show “ ” to indicate the second weight has been saved
• Repeat previous steps until all desired weights have been added to the total (you can accumulate up to 999 different weights)
• When you are done and want to display the accumulated total, press the ACCUM and PRINT key together. The accumulated number “ ” (the number of weights you are adding together) will flash on the display followed by the total
• The total will display by flashing between 2 sets of numbers
• There are 8 digits in total, the display will flash 4 at a time, the first 4 on the left and the last 4 on the right. For example if the first 4 digits are “0012” and the last 4 digits are “3456” the actual weight is 001234.56 or 1234.56 lbs/kg
• If you want to print the accumulated total, hold the PRINT key for one second while the last 4 digits of the total are shown
• To exit accumulation mode, wait for the last 4 digits to the right of the screen to appear, and then press and hold the ACCUM key for one second
• “ ” will be displayed, asking you if you want to keep the data?
• If NO you do not want to clear the accumulated total, then keep “ ”.
• If YES you do want to clear the total, then use the arrow key to change to “ ”
• Finally, press the PRINT key to select exit accumulation mode

Hold

There are 4 different hold functions you can choose from in the C11 parameter

1. Peak Hold: Grabs the highest weight (for materials testing, ie. tension and pulling force)

   • Press the HOLD key then add weight to the scale
   • The indicator will show the highest weight it recorded and hold it on the screen until a higher weight is placed on the scale

2. Manual Hold: Grabs the current weight and holds it so it will not change/fluctuate
   While weighing, press HOLD and the indicator will hold the current weight on the screen until HOLD is pressed again

3. Auto Hold: If the weight on the scale is above 20d (20 x division) and is stable, the indicator will hold that weight on the screen for 3 seconds then go back to general weighing
   Pressing the hold key is unnecessary, holding is done automatically when the scale is stable

4. Average Hold: Used for animal weighing, the indicator will display the average weight sampled from 3 seconds

   • Add livestock to scale and press HOLD
   • Indicator screen will show “ ” for 3 seconds, then display the average weight from those 3 seconds
   • Press HOLD again to exit holding mode

Print

• If the indicator is connected to a printer and the weight on the scale is stable press the PRINT key to print the current weight
• In accumulation mode hold the PRINT key for one second when the last 4 digits of the total weight are shown to print the total weight

Note: In tare mode the printer can not print if negative weight is shown

INDICATOR PARAMETER SETTINGS

The parameter settings menu has a calibration section (C01 to C07 explained above) and a parameter settings section (C08 and up).
To access the calibration section the seal switch (located at one corner of the PCB) must be OFF. This will allow access to all C01 and up settings. If the seal switch is ON, then only C08 and up can be accessed by the user. If you break the official seal by opening the back of the indicator to access the seal switch, you may need to have the indicator recertified. Be sure to adjust the seal switch back to the original setting after calibration/configuration has been performed.

To enter calibration/parameter settings, follow the procedure below:

1. Make sure the unit is set to either kg or lb
2. Press and hold the HOLD and PRINT key at the same time for 2 seconds
3. Navigate through the settings (C01 to C45) as shown in the table 4 below by using the arrow keys and return keys as labeled under each indicator button
4. Press the PRINT key to enter/edit the parameter setting
   Press the ACCUM key to save and exit settings at any time

HELPFUL DEFINITIONS

• Division: The amount of increments a scale offers. How accurate the scale can be
• Capacity: the maximum amount the scale can contain
• Initial Zero Range: The percentage of weight allowed on the scale when indicator is powered on that will automatically zero.
• example: If initial zero range is set to 10% of the max. capacity and your max. capacity is 100lbs, you can place up to 10lbs of weight on the scale and when the indicator is powered on, it will automatically zero out the weight.
• Manual Zero Range: The percentage of weight allowed on the scale where the indicator will let you manually zero (anything above this percent will be tared)
• Zero Tracking Range: A subset to the manual zero range; if the weight on the scale is not stable, the zero tracking range still allows you to zero within a set division of the scale
• Zero Tracking Time: A subset to the zero tracking range, it is the time allowed for the scale to fall within the zero tracking range tolerance and still qualify to be zero’d
• Overload Range: Weight allowance that is out of the set calibrated range. Adds a tolerance to the calibrated max. capacity without having to recalibrate.
• example: If your scale has a max. capacity of 1000lbs with a division of 1 and you set the overload range to 60, you can add 1060lbs of weight to the scale without it displaying an error code
• Negative Display: How far you can go in the negative direction before displaying an error code
• Standstill Time: How fast the scale will stabilize
• Standstill Range: How much the scale can fluctuate before being determined stable
• Digital Filter: For filtering moving weight, such as animals, It changes how sensitive the scale is to variations in movement.
• Noise Filter: A filter for how susceptible the scale is to general variations
• Baud Rate: The rate at which information is transferred in a communication channel. example: In the serial port context, “9600 baud” means that the serial port is capable of transferring a maximum of 9600 bits per second.

The following are the printing formats:

4-20 mA ANALOG OUTPUT (OPTIONAL)

The 4-20 mA analog output of the SL-7510 scale is a voltage sourcing sensor that will output current which is proportional to the calibrated scale’s weight range (i.e. 4 mA = 0 LBS and 20 mA = 10,000 LBS). It is important to note, that this is a sourcing output sensor (i.e. the sensor will source 9VDC with an output current range of 4-20 mA). Unlike many other “loop powered” type 4-20 mA sensors, an external supply voltage should not be connected to the unit’s 4-20 mA circuit, however, the ground connection (pin 6) of the DB-9 connector will need to be connected to the same ground as the data acquisition device which will be responsible for interoperating the 4-20 mA signal. This ground connection is imperative, as both the data acquisition device’s power supply and the scale’s internal 9VDC power supply will need to be on the same ground plane for the output current to be synced and measured correctly. Please reference Figure 6 as a visual clarification on how to connect your scales 4-20 mA output to a data acquisition device.
Below is a list of important notes when using the indicator with the 4-20 mA option

FIGURE 6. CONNECTION DIAGRAM

Below is a list of important notes when using the indicator with the 4-20 mA option

• Resolution: 1/1000
• Outside Load: 100-350ohms
• Inside connection: load input port pin “1” of J2, ground port pin “GND” of J2
• Outside connection: load input port pin 1 of DB9, ground port pin 6 of DB9
• To test the connection, connect a 250 ohm load; Locate a volt meter, and probe across the 250 ohm load. As the weight input to the indicator varies, the voltage of the volt meter will change accordingly
• Pressing the TARE key will reset to output current to 4mA
• 0-20mA output can be set by setting parameter C31 to 0
• Please note that this option will disable the RS232 weigh data output (serial ASCII data) that comes in the standard indicator

Calibration

• Press PRINT and HOLD key to go into configuration mode
• Go to C32 and press PRINT key
• The display should show [out-4] and output should be at 4mA
• Press the up/down arrow keys and the [out-#] will increase/decrease

Note: X corresponds to the output current. For example if out-12 is displayed, then 12mA should be the output. If not, press the left and right arrow key to adjust/calibrate

RELAY OUTPUT (OPTIONAL)

• The indicator can output 4 signals, which when connected to outside equipment, can perform an automatic control function and an upper/lower limit alarm function.
• Change parameter setting C33 following Table 6 below:

Table 6: Relay Output Parameter Setting

C33=0

| Out1| Turn off output function| No Output Signal
Out2| Turn off output function| No Output Signal
Out3| Turn off output function| No Output Signal
Out4| Turn off output function| No Output Signal

C33=1

| Out1| Turn on overload control function| Output overload control signal
Out2| Turn on compliance control function| Output compliance control signal
Out3| Turn on under-load control function| Output under-load control signal
Out4| Turn on stable control function| Output stable control signal
C33=2,3| Preserved, no function

Table 7 below shows the DB9 port pinout for the relay output option. Please note that this is optional and only available for the SL-7510 indicator ordered with this option.
The relay output option will disable the RS232 weigh data output (serial ASCII data) that comes in the standard indicator.
