Preface Thank you very much for your purchase! This manual covers safety precautions, brief introduction, technical specifications, operation interface, installation&connection, function&operation, fault treatment, working specification and so on. In order to make the product running at its best, please read this manual in advance, and reserve it for the future reading.
1. Safety Precautions Lithium Battery Installation A Lithium battery should be equipped in the weighing indicator. If it is not allowed to be transported together with the product because of embargo, please make a purchase according to the model offered by us and install it by yourself. ...
2. Brief Introduction 2.1 Operating Principle Shovel Loader Weigher is a dynamic weighing and auto-totalizing equipment installed on shovel loader without changing the original structure of shovel loader. When the lift-arm of Shovel Loader is lift to a certain height, the position sensor will trigger the weighing process, and the weighing indicator will collect the oil pressure signals from lower and upper oil chambers of arm-lifting oil cylinder.
Position Sensor Input Interface (POSITION) 1 Switch signal Input. Excitation Voltage Output: DC12V. Print Port (PRINTER) RS232. Digital Communication Interface (COM1) RS232。 Connectable: IPC/PLC and Wireless Module. Report Print 1000 Loading Records can be saved, queried and printed, and each record can contain 50pcs Single-bucket-loading-weight value.
3.3 Technical Specification of Position Sensor HALL Type Proximity Switches Operating Voltage: DC5~24V. Detecting Distance: 5~8mm. Response Frequency: 5KHz. Quiescent Current:Max. 2mA. Thread Size: M8× 1mm. Service Temperature: -25℃~+70℃. Protection Level: IP67. ...

5. Installation&Connection 5.1 Installation 5.1.1 Structure of Shovel Loader 1: Bucket; 2: Lift-arm; 3: Arm-lifting Oil Cylinder; 4: Oil Connecting Port of Upper Oil Chamber : Oil Connecting Port of Lower Oil Chamber. Related Operation Terms: Arm-up: Lift the lift-arm so that the bucket rises. ...
5.1.2 Installation of Weighing Indicator 1: Fastening Nut for Lateral Rotation; 3: Fastening Nut for Vertical Rotation; 4: Printer Weld the mounting bracket of the weighing indicator firmly on the metal frame of the shovel loader driving cab. The installation position should be convenient for operation. Suggestion: Install the weighing indicator in the driving cab of shovel loader and on the side the door will not be opened frequently.
5.1.3 Installation of Position Sensor Position sensor includes two modules: Proximity Switch module: Main Mounting Plate with a chute for length adjustment, Sub-mounting Plate with a chute for angle adjustment and Proximity Switch [Detecting Distance: 5~8mm]. Magnet Module: Thread Pole , Weld-nut, Tight-nut, Nylon Block, Upper Magnet Block and Lower Magnet Block.
5.1.4 Installation of Oil Pressure Sensor 1. Intallation Position The upper oil connecting port and lower oil connecting port of arm-lifting oil cylinder are the installation positions of oil pressure sensors. Suggestion: Install the oil pressure sensors on the arm-lifting oil cylinder which is at the same side that the weighing indicator installed on.
5.1.5 Cable Laying signal calble and position sensor signal cable should be laid in flexible pipe for Oil pressure sensor protection, and fix them with nylon strip. Try to keep signal calbles away from the place with high temperature and possible extrusion, and reserve their bending length enough to avoid being pulled apart.
5.3.3 Power Supply Connector (POWER) POWER Wire Color Description Voltage Black DC Input - ± 20% DC24V +24V DC Input + Note: Reverse polarity protection function available. The power switch of the weighing indicator should be turned off and ensure that the power cables are not charged before DC24V power connection to avoid short circuit fault.

After shoveling materials into the bucket, flip the bucket upward to the limit position. Then the magnet blocks on the lift-arm should be under the proximity switch. After the shovel loader reached the loading position, lift the lift-arm and bucket with the usual accelerator in actual operation and keep the accelerator stable.
