Understanding Kobelco excavator fault codes is crucial for efficient maintenance and minimizing downtime. Your machine's electro-hydraulic controller automatically stores detected abnormalities as faults, displaying them on the multi-function monitor. This guide provides a comprehensive overview of how to access and interpret these codes for various Kobelco excavator models, including the SK200/210/230/250-6E and SK330/350-6E series.

Growshine International, a leading importer and exporter of engineering machinery配件, 重卡配件, 农机配件, and 汽车配件, understands the importance of quick diagnostics. This detailed guide will help you navigate and understand Kobelco fault codes, ensuring your operations run smoothly.

Displaying Fault Codes

Here’s how to access the fault code display on your Kobelco excavator:

1. Turn the start switch to the “ON” position.

2. Within 10 seconds, press the buzzer stop switch 5 times consecutively to enter the fault code display screen.

3. The display will show up to 20 fault screens, starting with the earliest.

4. Fault data and engine hours will also be displayed. The screen shows “Engine Hours + 3 Fault Data”. If there are more than 3 fault data entries, the subsequent 3 entries will be displayed every 5 seconds.

5. Page navigation is done using the work mode selector switch and the buzzer stop switch. Pressing either switch will advance to the next page.

6. To stop the display, turn the start switch to the “OFF” position.

Clearing Fault History

To clear the fault history:

1. Enter the fault code display screen.

2. Simultaneously press and hold the work mode selector switch and the buzzer stop switch for more than 10 seconds.

3. When the display changes to “No abnormality,” all data will be cleared.

4. Turn the start switch to the “OFF” position.

Kobelco SK200/210/230/250-6E Excavator Fault Codes

Note: The main difference between the SK200-6 and SK200-6E is that the -6E model does not have a back pressure sensor and negative pressure sensors. The swing sensor is located on the multi-way valve, and there is only one alarm code B-7. Other differences are minor.

Understanding Common Excavator Parts

As specialists in engineering machinery parts, Growshine International offers a wide range of components. Here are some common parts and their explanations:

1. 风扇马达 (Fēngshàn Mǎdá / Fan Motor / Вентиляторный двигатель): The fan motor is responsible for driving the cooling fan in the engine compartment of equipment like the 卡特彼勒 345D (Caterpillar 345D). It helps regulate the engine temperature to prevent overheating.

2. 液压泵 (Yèyā Bèng / Hydraulic Pump / Гидравлический насос): The hydraulic pump converts mechanical energy into hydraulic energy, providing the power needed for various functions in excavators such as the 小松 PC200-7 (Komatsu PC200-7) to move its boom, arm, and bucket.

3. 喷油器 (Pēnyóuqì / Injector / Форсунка): Fuel injectors spray fuel into the engine cylinders at precise times. In a 三菱 6M60 (Mitsubishi 6M60) engine, the injectors ensure efficient combustion and engine performance.

4. 水温传感器 (Shuǐwēn Chuánsīnqì / Water Temperature Sensor / Датчик температуры воды): This sensor measures the temperature of the engine coolant. For instance, in a 斗山 DX225 (Doosan DX225), it sends temperature readings to the ECU to prevent overheating.

5. 空气滤芯 (Kōngqì Lǜxīn / Air Filter / Воздушный фильтр): The air filter cleans the air entering the engine, preventing dust and debris from causing damage. Regular replacement is essential in machines like the 常林 (Changlin) loader.

6. 曲轴 (Qūzhóu / Crankshaft / Коленчатый вал): The crankshaft is a crucial engine component that converts the linear motion of the pistons into rotational motion. You can find this in engines like the 五十铃 6HK1 (Isuzu 6HK1).

7. 增压器 (Zēngyāqì / Turbocharger / Турбокомпрессор): A turbocharger increases the power output of an engine by forcing more air into the combustion chamber. The 沃尔沃 D8E (Volvo D8E) engine often utilizes a turbocharger.

8. 行走马达 (Xíngzǒu Mǎdá / Travel Motor / Ходовой двигатель): The travel motor powers the movement of the excavator tracks, allowing it to move around the job site. This is vital for machines like the 小松 PC1250LC-10 (Komatsu PC1250LC-10).

9. 主控阀 (Zhǔkòng Fá / Main Control Valve / Главный распределительный клапан): The main control valve directs hydraulic fluid to various parts of the excavator, controlling the movement of the boom, arm, and bucket, as seen in the 神钢 SK260-8 (Kobelco SK260-8).

10. 油缸 (Yóugāng / Hydraulic Cylinder / Гидравлический цилиндр): Hydraulic cylinders convert hydraulic pressure into linear motion, powering the lifting and movement of the excavator's attachments, such as the 小松 大臂油缸 (Komatsu Boom Cylinder).
