Transmitter Installation Installation Requirements Observe the following conditions for correct installation of the transmitter and the load receiver: • Flat, level support surface. • Stability and absence of vibrations. • Absence of aggressive dusts and vapor. • Absence of drafts. •... -
Page 9: Electrical Precautions
The cable ends (connectors, leads, terminals, etc.) must be installed correctly; the cable shielding must be kept intact until close to the connection point. • If the transmitter is placed inside an electrical panel, a shielded cable must also be used for the power supply. © Rice Lake Weighing Systems • All Rights Reserved... - Page 10 RECOMMENDED DISTANCES AND CABLE CLASSIFICATION Category I Category II Category III Category IV ≥ 3.94 in (100 mm) ≥ 7.87 in (200 mm) ≥ 19.69 in (500 mm) Distance ≥ 3.94 in (100 mm) ≥ 19.69 in (500 mm) ≥ 19.69 in (500 mm) Fieldbus, LAN network (PROFIBUS or Ethernet).

Page 11: System Grounding
Connect the serial cable shield to the earthing point (or earth bar) inside the panel. To avoid any undesired effects, the earth reference of the connection cable, power supply and transmitter must be at the same potential. © Rice Lake Weighing Systems • All Rights Reserved... - Page 12 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.

Page 16: 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 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. -

Page 28: 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. -
