  • Page 15: Load Cell Installation

    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 section “Wiring diagrams”). 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.

  • Page 31: Anti-Peak Filter

    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.
