  • Page 4: Introduction

    Introduction 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.

  • Page 5: Warnings

    • 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. Forklift requirements For proper operation of the system, the forklift must meet the following requirements: •...

  • Page 6: Kit Components

    Kit components The LTP kit consists of: • Weight indicator • Pressure sensor • Fixing bracket to the forklift • Reference stickers • Power supply unit (optional) • Thermal printer (optional) 1. Weight indicator Powered directly from the forklift battery (via optional internal power supply), 5-key keypad and LCD Vertical tilt can be adjusted via the integrated bracket.
  • Page 7 DISPLAY AND KEYBOARD ITEM ICON DESCRIPTION This indicates that the scale is empty (gross zero). This indicates that the weight is unstable. The net weight is displayed. Note: A tare has been stored. 4 / 5 The gross weight is displayed. This indicates the battery level: A tare has been blocked.

    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. 3. Fixing bracket for the indicator in the cabin Bracket for horizontal adjustment during installation. 4.
  • Page 9 5. Power supply unit (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.

  • Page 10: Kit Installation

    Kit installation 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: Lower the forks to their maximum Place the forks on a stable object.

  • Page 11: Sensor Installation

    Sensor installation The sensor is connected to the hydraulic system of the forklift using a compatible tee fitting (not included in the kit). Install the sensor in the pressure pipe that guides the cylinder (the sensor should be positioned as close as possible to the cylinder). The sensor must be installed with the cable pointing downwards.

  • Page 12: Installing The Indicator

    Installing the indicator FIND A SUITABLE LOCATION FOR THE INDICATOR: Below are some installation examples: Adjust the orientation of the indicator vertically and horizontally so that it is clearly visible and easy to reach. INSTALLING THE INDICATOR BRACKET Install the bracket to the indicator using the supplied fixing components. The power cable and the sensor cable are then connected via the two side cable glands.

  • Page 14: Applying Reference Stickers

    Applying reference stickers Apply the stickers at a height of at least 50 cm from the ground. Apply the arrow-shaped sticker to the forklift plate and the rectangular sticker to the upright. These stickers identify the reference area: perform all weighing operations when the arrowhead is inside the yellow band. The operator must have full visibility of the reference stickers.

  • Page 15: Calibration

    Calibration FOREWORD The system detects the weight based on the pressure trend as a function of time. As each forklift has a different behaviour, it is recommended to use the LTPTOOL PC software to optimise the response speed and accuracy of the weighing system according to the conditions and characteristics of the forklift.
  • Page 16 4 OPTIMISING TIMES WITH LTPTOOL Select the “Settings” tab and select the serial port. Click on “Connect”. Set the number of up / down cycles (default = 5). By increasing the number of cycles, the procedure becomes longer but the results will be more reliable.

  • Page 19: Calibration Linearisation

    Calibration linearisation Perform the linearisation after calibration to increase weighing accuracy. Linearising the calibration means adding calibration points (up to 6). The more calibration points that are added, the more accurate the system will be. We recommend defining at least 2 linearisation points. Example: On a system with a capacity of 2000 kg, assuming an initial calibration with 2000 kg, we recommend adding 3 calibration points at 500 kg, 1000 kg, 1500 kg.
