YA00019911 Original Excavator Monitor for Hitachi ZX70

The part number YA00019911 is an original monitor specially designed by Hitachi for the ZX70 series (with a total working weight of approximately 7 tons) ultra small hydraulic excavator. Its universal models usually cover small models on platforms such as ZX70-5A, ZX70-5G, and ZX60. As the core of the overall information display, it integrates engine water temperature, fuel level, hour meter, fault codes, and various working status alarm lights into one. The "SET", "PLAY", and "SELECT" buttons at the bottom of the screen indicate that they support parameter settings and display interface switching. As the original human-machine interaction interface, its interface definition is completely matched with the vehicle's circuit system

This product is an integrated monitoring instrument that combines pointers and numbers. The casing is made of engineering plastic, and the left pointer gauge is the engine coolant temperature gauge (scale C-H), while the right pointer gauge is the fuel level gauge (scale E-F). The central square monochrome LCD display screen is used to display digital information such as hours and fault codes. The three physical buttons below (SET/DIPLAY/SET) are used for menu operations. The metal sheet connected on one side is the grounding and mounting bracket. Its working voltage is DC 12V/24V, and it receives signals from sensors and ECU through the wiring harness. The core function is to provide drivers with intuitive and reliable machine status monitoring, which is the basic instrument to ensure the normal operation of equipment.

Basic operation: You can switch the information displayed on the central screen (such as hour meter, mileage, etc.) by pressing the "PLAY" key; The "SET" and "SELECT" keys can be used to set maintenance reminders or view diagnostic information. Daily maintenance: Clean the screen and dial with a soft, slightly damp cloth every week, avoiding the use of corrosive solvents. Check if the instrument harness plug is secure and if there is any water ingress or oxidation every 500 working hours. Troubleshooting: If there is a black screen or all pointers malfunction, the fuse (usually 5A/10A) and power supply should be checked first; If a single pointer gauge is inaccurate (such as an oil gauge but a water temperature gauge is normal), priority should be given to checking the corresponding sensor (such as an oil level float) and its circuit.
