Key Functions
Configuration menu
| Decreases digit / Scrolls down.
| Increases digit / Scrolls up.
| Enters the setup. Selects digit to modify.
| Enters a step / Confirms.
| Clears / Exits a step (no save).
Weighing mode
| Clears the displayed gross weight.
| Short press: executes semiautomatic tare. Long press: allows to enter known
tare.
| Activates / deactivates the function.
| Short press executes data transmission on the printer serial port.
Long press: Setpoint configuration.
| ON/Standby of the instrument.
Indicator Light Descriptions
| 1 | Weight on zero. |
|---|---|
| 2 | Unstable weight. |
| 3 | A tare is active. |
| 4 | A function is active. |
| 5 | Digital output 1 is active. |
| 6 | Digital output 2 is active. |
Configuration Menu
- Reboot the weight transmitter
- Press the key when display shows the 888888 message:
HOW TO EXIT THE MENU AND SAVE YOUR CONFIGURATION
- Press
**C**key repeatedly until save? appears; press ** to save or press C** to exit without saving
Maximum Scale Capacity, Increment and Decimal Point Settings
Set the decimal point position and the minimum scale increment*1
` **( 0,001 - 0,002 - 0,005 - 0,01 - 0,02 - 0,05 - 0,1 - 0,2 - 0,5 - 1 - 2 - 5
- 10 - 20 - 50 ).*`
Set the maximum scale capacity2 (max 999999 ).
Examples:
For a 60000 lb scale, with 2 lb
increment: div.deC = **2**
CapaC = **60000**
For a 10000 g scale, with 0.1 g increment:
**div.deC**= **0,1**
CapaC = **10000,0**
For a 3000 lb scale, with 0.05 lb increment:
div.deC = **0,05**
CapaC = **3000,00**
1 Increment = the amount that the scale will increment by as weight is added or removed.
2 Maximum capacity = the maximum weight that can be measured using the scale you are creating.
Theoretical Calibration
Set the total load cells capacity (up to 999999).
Set the load cells sensitivity (up to 999999) .
Dead load weight (from -9999.9 to 99999.9)
Zeroi Mechanic Tare (pre-tare zeroing)
Zeroing of the pre-tare (or mechanical tare).
This functionality allows to zero the weigh of the scale structure (e.g. empty
silo, conveyor, etc.) without changing the calibration in memory
Calibration with Sample Weight
Zero point acquisition.
Sample weight acquisition.
Load Cell Diagnostics (µV/V)
It allows to verify signal of each channel. It must be included into the range
0 to 3 mV/V.
Signal have to be stable and it have to increase by increasing the weight on
the scale.

HOW TO PROGRAM SETPOINTS
Fieldbus Settings
Set the IP address:
Weight Filter
The active weight filter is displayed, alternating with the weight value.
Press keys to scroll through the available filters (from slowest to fastest,
F1 to F11).
Programming Errors
| MESSAGE | DESCRIPTION | SOLUTION |
|---|
| Calibration error| First calibrate the zero point (zero), then proceed with
sample weight acquisition (span) (section 9).
| Calibration error| Check the connection of the load cell. Verify the load
cell signal is stable, valid and greater than the previously acquired point.
| Calibration error| Increase the calibration weight.
| Calibration error| Check the signal from the load cell increases when weight
is incremented on the scale.
| Calibration error| Repeat calibration and verify capacity and division have
been correctly set.
| Instrument not configured| Transmitter needs to be configurated.
| Calibration error| Verify the signal from the load cell is not negative.
| Calibration error| Verify the signal from the load cell is not negative.
| Weight unstable| Check in parameter that the signal is stable.
If the connection of the cells is with 4 wires, check that the sense jumpers
are inserted.
| A/D converter error| Converter failure. Reboot the instrument.
| Global load cell error| Signal anomaly: check the load cells connection.
