GENERAL NOTES: • All earth cables must be of suitable length, so as to obtain an overall resistance of the earthing system of less than 1 Ω. • If the weighing system involves large and/or outdoor structures (weighbridges, silos, etc.): - the earth connection must be made by connecting the earth cables to an earth bar and the earth bar to the earth post with a cable having a cross-section of not less than 1-1/0 AWG (50 mm - the earth post must be placed at a distance of at least 33 ft (10 m) from the structure.
Load Cell Installation After carrying out the instructions for the platform or load receiver, the shielded cable from the cell must be properly connected to the terminal block of the transmitter (see page 17). The transmitter has one channel for 6-wire connection to load cells (using the REFERENCE). The REFERENCE allows you to compensate for any voltage drop on the section of cable connecting the transmitter to the load receiver.
Advanced Programming Menu The advanced menu contains all the transmitter configuration parameters for the most advanced adjustments. Access the Advanced Menu and Save Changes Reboot the transmitter. Press the key when the display shows 888888. HOW TO EXIT THE SETUP AND SAVE CHANGES Press several times, until the display shows “save?”.
Calibration with Sample Weights 888888 f.mode Setup ConfiG pre.Cal Calib deCi u.m. ranGe1 Calib.p equal n tp Tp 0 ddt1 tp 1 ddt2 Tp 2 ddt3 tp 3 CALIBRATION PROCEDURE: Set the calibration parameters: = Number of decimals. deCi = Unit of measurement (kG, G, t, lb). u.m.
Manual Calibration 888888 f.mode Setup ConfiG pre.Cal Calib deCi man.Cal If you know the number of ADC converter points for a known weight (for example if you want to copy the calibration from one transmitter to another) the calibration points can be entered manually: The display shows mod.pnt, and then the last calibration point.
Anti-peak Filter The transmitter has an additional filter for the elimination of sudden weight peaks (e.g. shocks or falling material). The following parameters, opportunely configured, allow you to eliminate the peak by blocking the weight for its entire duration. The weight is blocked if it remains within the number of divisions set in PK.LK.DV for the time set in PK.LK.TM and is subsequently unblocked if the weight deviates from the blocking value for a number of divisions greater than PK.DIV (or PK.BN.DV) or if the time set in PK.TIME has elapsed.
Gravity 888888 f.mode Setup ConfiG pre.Cal From 9.75001 to 9.84999. Grav = 9.80543. This parameter allows you to correct the gravity acceleration value. Before calibration, set the value of the calibration zone. Next, set this value to the value of the zone of use. Any difference between the two values will be automatically compensated.
Zero Tracking This menu allows to set zero tracking, i.e. the compensation parameter of the thermal drift of the scale; the set value corresponds to the number of divisions that is reset to zero in the fixed time of 1 second. tr 10 10 divisions.
Alibi Memory The alibi memory allows you to store the weight values transmitted to the computer for further processing and/or data integration. The stored values can then be retrieved from the PC port or directly on the display of the transmitter for later checking. Enabling the Alibi Memory 888888 F.mode...

Serial Commands By selecting the PC port on demand mode (onde), you can communicate with the transmitter via serial commands. For each command received, the transmitter emits a string containing the response (refer to the command description) or one of the following signals: Command sent when sending a correct command.
