Доброго времени! Ребят подскажите, такая проблема: при начале движения загорает ндикатор красным кузов и непрерывно звучки сигнал! Как отрегулировать и избавиться от этого звука?
To adjust and eliminate the continuous sound from the red body indicator (engine system caution lamp) on a Komatsu HM400-5 when starting to move, follow these steps:
1. Check SCR Information Screen: Press the menu switch to display the “SCR Information” screen and read the message (e.g., “Please inspect and maintain SCR system”).
2. Understand the Warning Level: If the action level “L03” is lit in red and the engine system caution lamp is red, the machine is in a warning or continuous warning state. The DEF system caution lamp may also be yellow.
3. Derated Engine Power: Engine power is already reduced (derated) as part of the warning.
4. Move to a Safe Location: Stop operating the machine and move it to a safe place.
5. Contact Komatsu Distributor: You must contact your Komatsu distributor to inspect and service the SCR system.
The continuous sound and warnings will not stop until the cause is diagnosed and corrected by authorized service.
