Dear Customer,
Thank you for purchasing a DINI ARGEO product.
This manual explains the installation and commissioning for the hydraulic weighing system for forklifts.
In particular, the installation of the sensor and the calibration of the indicator are described (with the corresponding adjustable ranges of values
and practical programming examples) to assist the technician during system installation.
For any additional information or specific requests, please contact your local dealer.
This publication is optimised for A4 printing.

• The weighing system does not change the safety regulations normally applied to the forklift.
• Before weighing, make sure that the forklift is stationary, on a flat surface and that there are no people in the area around the load.
• The employee training on the use of the system is the purchaser’s responsibility.
• Please read this manual carefully before using the system.
• Assistance must only be carried out by personnel authorised by Dini Argeo.
• Dini Argeo is not responsible for any weighing errors resulting from improper use of the system.
For proper operation of the system, the forklift must meet the following requirements:
• Minimum friction between the sliding parts.
• No oil leaks.
• Good lubrication of the mast and chains.
• Good level of cleanliness.
• Use of an oil with a high viscosity index.
To make the system repeatable (i.e. to display the same weight when weighing in succession), the forklift must be kept in constant condition,
therefore regular cleaning and maintenance must be carried out.

3. Fixing bracket for the indicator in the cabin
Bracket for horizontal adjustment during installation.
2. Pressure sensor
Stainless steel sensor, IP65 protection rating and hydraulic connector with 1/4 inch parallel PSB female.
Sensor dimensions: length: 73.5 mm; diameter: 24.5 mm.
4. Reference stickers
Stickers used to identify the height range of the forks within which the weighing operations are to be carried out.
To be applied to the structure of the forklift.

OBTPRLT thermal printer with integrated bracket for fixing to the forklift. Powered directly from the weight indicator (if optional internal
power supply unit is present).
5. Power supply unit (optional)
6. Thermal printer (optional)
The appropriate optional ALxxV5 power supply unit with 18 to 72Vdc or 40 to 160Vdc input can be chosen according to the voltage on the forklift.
The ALxxV5 power supply units can be installed inside the weight indicator and can simultaneously power the OBTPRLT printer, optimising
the wiring of the various components.

Before installation
• Check that the maximum oil pressure is lower than the maximum value indicated on the sensor datasheet (4000 psi = 280 bar).
• Remove the pressure in the hydraulic circuit; this can be done in two ways:
A. Lower the forks to their maximum
andmove forward.
Make sure the chain is loose.
B. Place the forks on a stable object.
Make sure the chain is loose.
