Q1: What is the product identity and its applicable scope for Volvo EC140C and EC220C?
A1: This product is the Premium Excavator Monitor Display Panel (OEM part number: VOE14544928, compatible with replacement part 14609502) – a high-performance Human-Machine Interface (HMI) exclusively engineered for Volvo EC140C (14-ton class) and EC220C (22-ton class) mid-size crawler excavators :
- EC140C: Matched with Volvo’s 4-cylinder diesel engine (rated power: 89kW @ 1800rpm, ISO 9249 standard), deployed in municipal engineering, small-to-medium earthmoving, landscaping, and residential construction (continuous light-to-medium load operation) Volvo Construction Equipment;
- EC220C: Paired with Volvo D6E inline 6-cylinder diesel engine (net power: 115kW @ 1800rpm, max torque 730Nm), designed for infrastructure construction, foundation works, and small-scale quarrying (continuous medium-to-heavy load operation) .
As a premium replacement/upgrade component, this panel addresses common OEM panel limitations (e.g., low sunlight visibility, short service life) while complying with Volvo’s original electrical, mechanical, and software specifications for EC140C/EC220C. It is suitable for routine maintenance, post-fault replacement (screen cracking, communication failure, firmware crash), and fleet upgrades to enhance operational visibility and data monitoring accuracy.
Q2: What core functions does the Premium Monitor Display Panel provide for EC140C and EC220C?
A2: The panel delivers Volvo-specific HMI functions with enhanced precision, tailored to EC140C/EC220C’s operational demands:
Core Functions (Both Models)
- High-precision real-time data display: Clearly shows critical parameters including engine speed, fuel level, hydraulic pressure (EC140C: max 34.3MPa; EC220C: 34.3MPa for working circuit, 27.9MPa for swing circuit ), coolant temperature, working hours, and attachment position (±0.8mm accuracy), with a high-brightness screen for sunlight readability.
- Volvo-standard fault diagnosis: Detects engine/hydraulic/electrical system faults, displays Volvo-specific Diagnostic Trouble Codes (DTCs), and triggers multi-level alerts (85dB audio buzzer + color-coded LED indicators) for critical issues (e.g., low engine oil pressure, hydraulic fluid overheating, fuel filter clogging).
- Work mode & parameter tuning: Enables on-site adjustment of idle speed, hydraulic flow rate, and work modes (Economy/Power/Attachment) – EC140C prioritizes fuel efficiency for municipal tasks, while EC220C supports heavy-load Power mode for foundation digging .
- Telematics interoperability: Syncs with Volvo’s fleet management system and EC140C/EC220C ECU, supporting remote data logging, operational performance tracking, and predictive maintenance reminders (e.g., oil/filter replacement based on working hours).
Model-Specific Optimizations
- EC140C: Streamlined interface with simplified fuel consumption monitoring and basic fault alert logic, optimized for light-load scenarios;
- EC220C: Enhanced hydraulic pressure curve display and overload protection prompts, matching its 144kN bucket digging force and 105kN arm digging force for medium-heavy operations .
