Introduction Dear Customer, Thank you for purchasing a DINI ARGEO product. This manual contains all the instructions for installing and commissioning of the DGT4X digital weight transmitter with digital load cells. While thanking you for purchasing this product, we would like to draw your attention to some aspects of this manual.
Transmitter installation Installation requirements Observe the following conditions for correct installation of the transmitter: • Flat, level surface. • Stability and absence of vibrations. • Absence of aggressive dusts and vapour. • Absence of drafts. • Ensure that the platform is level or that the load cells are evenly supported. •...
Electrical precautions • Use a regulated mains supply within ± 10% of the rated voltage. • The electrical protections (fuses, etc.) are the responsibility of the installer. • Observe the recommended minimum distances between cables of different categories (see table on page 10). •...

RECOMMENDED DISTANCES AND CABLE CLASSIFICATION Category I Category II Category III Category IV ≥ 100 mm ≥ 200 mm ≥ 500 mm Distance ≥ 100 mm ≥ 500 mm ≥ 500 mm Fieldbus, LAN network (PROFIBUS, Ethernet, Devicenet...). Shielded data cables DC supply cables with (RS232...).
Earthing of the system For correct earthing and optimal system operation, the transmitter, load cells, junction box, if any, and weighing structure must be earthed. TRANSMITTER The earth connection must be made via the appropriate terminal. The cable cross-section must be less than 2.5 mm .

Technical features POWER SUPPLY 12 - 24 VDC LPS or with class 2 power supply. MAXIMUM ABSORPTION DGT4XDL: 4 W (without load cells) DGT4XDLAN: 4,5 W DGT4XDLPRONET : 7,5 W OPERATING TEMPERATURE From -10°C to +40°C. DISPLAY DIVISIONS 10000e, 2 x 3000e for legal weighing, expandable up to 800,000 for internal use (with a minimum cell signal of 1.6 mV/V).
Load cell installation After carrying out the instructions for the platform or load receiver, load cell connections can be made. There are two scenarios for connection depending on type of load cells. • RCD and RCPTD load cells attach to the indicator via a junction box. A shielded cable from the junction box must properly connect to the RS485 connector of the transmitter.
Cell Wiring Output The firmware is compatible with four load cells: RCD, RCPTD, RL541DC and RL5426DC. RCPTD Colour Description Colour Description Input + White Input + Black Input - Brown Input - Green Output (A +) Grey Input Signal (A +) White Output (B -) Pink...
