Product representation

Detailed product information

Structural composition: The Sany Excavator Frontier block mainly consists of a fuse cover, fuse base, fuse nests, as well as various fuses and safety devices. The fuse cover, as a rule, is designed so that it can be opened, which is convenient for repair and replacement of fuses; The base of the fuse is made of insulating material, used to fix and support fuses and fuse and has good insulation characteristics; The fuse holder is used to fix fuses and fuse.

The principle of operation: when an abnormal situation occurs in the chain, for example, overload or short circuit, as a result of which the current exceeds the rated current of the fuse, the fuse is automatically burned out, thereby turning off the circuit and preventing damage to the circuit and equipment due to excessive current, thereby performing a protective function. In addition to fuses, the fuse block can also be equipped with other safety devices, such as circuit breakers and fuses that can automatically turn off the circuit when the electrical malfunction occurs, providing more complex protection functions.

Functional features: the fuse unit has functions such as overload protection, super -flow protection, short circuit protection and insulation protection. It can effectively prevent damage to the excavator electrical system due to an abnormal current, for example, the engine control module, the display screen, various sensors, etc., ensure the stable operation of the electrical system of the excavator, reduce the risk of equipment failure and increase the safety of work.

Applicable models: various models of Sany excavators are equipped with various fuse blocks. For example, fuse blocks suitable for excavators of different carrying capacity, such as SY55, SY135 and SY215, are designed purposefully in terms of size, internal layout and fuse characteristics to comply with the requirements of protecting electrical systems of various models.

Stages of installation

Preparation: First, make sure that the excavator is stopped, the engine is turned off, and the negative terminal terminal is disconnected to prevent lesions with electric shock or a short circuit during the installation process. Prepare the tools necessary for installation, such as screwdrivers, pliers, island, etc., as well as the fuse block of the corresponding model.

Remove the old fuse unit (if any): Find the original fuse unit, which is usually located in an electric control unit near the cabin or side of the car. Using a screwdriver, unscrew the fasteners or open the clamps, carefully remove the old fuse unit, be sure to save the screws and other parts, and mark the joints of each line.

Install a new fuse unit: install a new fuse unit in a given position, combine it with mounting holes and fix it with screws to provide a reliable installation. In accordance with the previously marked provisions of the lines connection, carefully insert each line of the line into the corresponding interface of the new fuse unit and insert it tightly to provide a reliable electrical connection. For some connectors of wires, for fixing which you need to tighten the screws, use a screwdriver to tighten them moderately.

Checking and testing: After installation, carefully check the correctness and reliability of all linear compounds, as well as the absence of weakening or incorrect connection. After checking, connect the negative pole of the battery, run the excavator and check if the functions of the electrical system work normally, such as the instrument panel display, lighting, various controls, etc. At the same time, check if the fuse unit is heated, whether it is smoked He, etc.

Common malfunctions

A blocked fuse: this is the most common malfunction. The reasons can be an overload of the electrical system, for example, the simultaneous use of too much powerful electrical appliances; short circuit in the chain, damage to the insulating layer of the wire, leading to direct contact between positive and negative poles; or internal malfunction of electrical equipment, for example, a short circuit in the engine. When the fuse is burned, the corresponding electrical equipment stops working.

Bad contact: poor contact is possible between the fuse and the fuse holder, as well as between the cable of the power cable and the interface of the fuse of the unit. The manifestation of this is that electrical equipment is unstable, sometimes good, sometimes bad, or with the vibration of an excavator, electrical equipment suddenly loses power. Long -term poor contact can also lead to heating the contacting parts and accelerate the aging of the components.

Damage to the fuse block: external exposure or prolonged exposure to harsh operating conditions (such as high temperature, humidity and dust) can lead to cracking of the fuse of the fuse block and damage to the internal printed circuit board, which will affect its normal functioning. In addition, aging and failure of the internal components of the fuse can also lead to the fact that the fuse block will not be able to normally perform its protective function.

Preparation of tools: Prepare all the tools necessary for installation, such as a cross screwdriver of the corresponding size, flat screwdriver, witty, tools for cleaning wires, isolet, multimeter, dynamometric key (if necessary), etc.

Choosing a place: choose an even, dry, well -ventilated and lit place for the excavator parking and make sure that there are no obstacles around for ease of use. At the same time, install warning signs to prevent the erroneous actions of other persons.

Turn off the equipment: turn off the excavator engine, turn on the manual brake and make sure that the equipment is stopped. Then open the cover of the battery compartment, with the help of a wrench, unscrew the terminal nut on the negative terminal of the battery, remove the negative cable and wrap it with insulating tape to prevent random contact with electricity.

Checking details: Check the list of products to make sure that there is a full set of fuses and accessories for the new Sany excavator, including fuses, fuse holders, linear plugs, fasteners, etc. At the same time, check if there are damage fuses on the block, deformations, cracks, etc. If there are any problems, replace it on time.

Stages of installation

Removing the old fuse unit

Accommodation: depending on the model and the operating manual of the excavator, find the installation site of the old fuse unit, which is usually located under the instrument panel inside the cabin, in the electric control unit outside the cab or next to the motor compartment.

Place the lines: use a marker or sticker to mark each line connected to the old fuse block, write down the connection position and line number so that you can accurately connect it when the new fuse unit is subsequent. This step is very important, especially for excavators with a large number of complex wiring to avoid failures in the operation of electrical wiring caused by improper wiring.

Remove the mounts: use a screwdriver to unscrew the screws or open the clamps that attach the old fuse unit. Some fuse blocks may also require removal of some protective lids or decorative panels before access. During the removal process, be careful not to damage the surrounding components.

Divide the lines: disconnect the linear forks on the old fuse block one after another. For some forks, which are tightly inserted and taken out, you can use the sprouts to gently squeeze both sides of the fork and pull it out with uniform effort. Do not pull the wires with force so as not to damage the lines. If there are screw terminals on the line, unscrew the screws with a screwdriver and loosen the terminals.

Remove the old fuse block: after all the mounts and wiring are removed, carefully remove the old fuse block from the installation site and place it in a safe place.

Installation of a new fuse unit

Accommodation and installation: Place a new fuse unit in the place of installation of the old fuse unit, making sure that the mounting holes coincided. For some fuse blocks for which the installation bracket is required, first secure the bracket at the installation site, and then install the fuse block on the bracket.

Fasten the fuse block: use the screwdriver to screw the fasteners into the fasteners. Tighten the screws gradually diagonally to make sure that the fuse unit is reliably installed without shaking or displacement. When tightening the screws, be sure to apply a moderate force to avoid cracking of the fuse of the fuse block or damage to the mounting holes due to excessive effort.

Connect the lines: in accordance with the numbers of the lines and the positions of the joints marked earlier, insert the lines plugs into the corresponding interfaces of the new fuse unit at one, making sure that the plugs are inserted to the stop, and the clicks mean that the plugs are inserted reliably. For terminal blocks with a screw mount, insert the wires into the terminal holes and tighten the screws with a screwdriver to make sure that the wires are securely connected and have good contact. When connecting the lines, carefully check the connection of each line to make sure of the absence of incorrect or absent connections.

Install the fuse: In accordance with the requirements of the electrical system of the excavator, insert the fuse to the corresponding specification into the fuse holder in the fuse unit, observing caution so as not to insert it upside down. When installing the fuse, make sure that the fuse and the fuse holder are in good contact to avoid a false connection.

Checking and testing

Appearance check: After installation, carefully check the appearance of the fuse block to make sure that all lines are connected correctly and reliably, without weakening, falling off or intersection. Check if the fuse is installed and is the fuse holder damaged.

Electrical conductivity check: Use the multimeter resistance range to check the integrity of each connecting line to check its conductivity and the presence of a short circuit or a chain break. During the test, tape the multimeter of the two ends of the chain, respectively. If the multimeter shows the resistance value equal to zero or close to zero, this means that the circuit draws the current normally. If the displayed resistance value is infinite, this means that the circuit is open, and you need to check the connection of the circuit and eliminate the problems.

Power Testing Test: Having made sure that the external inspection and verification of the electrical characteristics are performed correctly, again connect the negative battery cable to the battery terminal and tighten the nut. Then run the excavator, check if the indicators on the dashboard are burning, and check if all the functions of the electric system work normally, for example, headlights, wipers, beeps, displays, various control handles, etc. During the on checking for the power of power, pay attention on abnormal heating, smoking, smell, etc. If there are any deviations, immediately stop the check and find out the cause of the malfunction.

Cleaning after installation

Clean the installation location: after the installation is completed, clean the installation site, pack the tools and the remaining parts, and also properly save or dispose of the old fuse block.
