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.

| Short press executes data transmission on the printer serial port.
Long press: Setpoint configuration.
| ON/Standby of the instrument.

Indicator Light Descriptions

Configuration Menu

1. Reboot the weight transmitter
2. Press the key when display shows the message:

HOW TO EXIT THE MENU AND SAVE YOUR CONFIGURATION

1. Press key repeatedly until appears; press to save or press to exit without saving.

Maximum Scale Capacity, Increment and Decimal Point Settings

| Set the decimal point position and the minimum scale increment1

Set the maximum scale capacity2 (max ).
---|---

Examples:

For a 60000 lb scale, with 2 lb increment:| For a 10000 g scale, with 0.1 g increment:| For a 3000 lb scale, with 0.05 lb increment:
---|---|---

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 ).
Set the load cells sensitivity (up to ).
Dead load weight (from -9999.9 to . ).
---|---

Zero Mechanical 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 Cells 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.

Fieldbus Settings

Weight Filter

The active weight filter is displayed, alternating with the weight value.
Press and keys to scroll through the available filters (from slowest to fastest, F1 to F11).

Programming Errors

sample weight acquisition (sp n) (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.
