Mitsubishi Elevator LOP Display Board LHH-1005E G21/G24: Usage Guide, Replacement Cycle & Trusted Supply from Nanjing Zhuye

The Mitsubishi Elevator LOP Display Board LHH-1005E G21/G24 is a vital landing-side interface exclusively engineered for Mitsubishi elevator systems—including NexWay, ELENESSA, and MAXIEZ series—essential for residential complexes, commercial buildings, transit hubs, and public facilities worldwide. As the “landing information hub,” this dual-variant LOP board (G21 for standard configurations, G24 for extended status functions) provides clear real-time feedback to waiting passengers: elevator car position, direction indicators, door status, and service alerts. It integrates Mitsubishi’s proprietary high-brightness LED technology, anti-interference communication circuits, and weather-resistant design—upholding the brand’s strict standards for visibility (viewing angle ≥170°, brightness ≥400 cd/m²), responsiveness (signal latency ≤30ms), and operational reliability in high-traffic environments.

Compliant with global elevator safety and usability standards (EN 81-20/50, ISO 13407, UL 94, JIS A4300), the LHH-1005E G21/G24 features a durable, landing-adapted design: a scratch-resistant polycarbonate front panel, flame-retardant ABS housing (UL94 V0 rating), low-power LED modules (energy consumption ≤3W), and dust/waterproof connectors (IP55 protection). This robust construction withstands harsh landing environments—temperature fluctuations (-15°C to +55°C), humidity (up to 90% non-condensing), minor impact, and dust accumulation—critical for preventing display failures, unresponsive call buttons, or passenger confusion. For maintenance teams, facility managers, and elevator service providers, mastering proper installation, configuration, and replacement timelines is vital to ensuring user experience, regulatory compliance, and elevator operational efficiency. Nanjing Zhuye Elevator Parts, a trusted supplier of authentic Mitsubishi components, delivers the LHH-1005E G21/G24 that meets Mitsubishi’s original manufacturing specifications—guaranteeing seamless compatibility, clear visibility, and long-term reliability.

Proper Usage Methods of Mitsubishi LHH-1005E G21/G24 LOP Display Board

1. Pre-Installation Preparation

Before installation or replacement, prioritize safety by shutting off the elevator’s main power supply, engaging the emergency stop button, and securing the landing panel area with warning signs and lockout-tagout (LOTO) devices. Inspect the new LHH-1005E variant (G21/G24) for physical damage—cracked display panel, damaged call buttons, loose connectors, or bent circuit board pins—defects that compromise functionality or safety. Nanjing Zhuye’s strict quality control process ensures each unit arrives in optimal condition: intact LED modules, responsive tactile buttons, secure wiring harnesses, and pre-loaded Mitsubishi-compatible firmware.

Verify compatibility with your Mitsubishi elevator model by cross-referencing the technical manual or consulting Nanjing Zhuye’s technical support team. Ensure three key details align: (1) the variant (G21: basic floor/direction display; G24: adds service status/overload alerts) matches the landing’s functional requirements, (2) the mounting dimensions (160x100x40mm) fit the landing panel cutout, and (3) the communication protocol (Mitsubishi’s CANopen) is compatible with the main control board. Using an incompatible LOP board can result in mismatched display data, unresponsive call buttons, or communication errors. Additionally, prepare the installation area: Clean the landing panel cutout to remove dust and debris, disconnect the old board’s wiring harness (label cables for easy reinstallation), and gather necessary tools (Phillips screwdriver, wire strippers, anti-static wristband).

2. Installation & Configuration Steps

Panel Preparation: Remove the old LOP display board by unscrewing the mounting screws (typically 2–4 screws) from the landing panel. Disconnect the wiring harness by releasing the locking clip—avoid pulling cables to prevent insulation damage. Inspect the landing wiring for fraying, corrosion, or loose connections—repair or replace with genuine Mitsubishi-compatible wires from Nanjing Zhuye if needed.
Board Installation: Align the LHH-1005E G21/G24 with the landing panel cutout, ensuring the display faces outward and mounting holes align. Secure the board with corrosion-resistant screws (torque to 0.6–0.8 Nm) to prevent vibration-induced loosening—over-tightening can crack the polycarbonate panel. Connect the wiring harness to the board’s connector until it locks into place, verifying correct pin alignment (refer to Mitsubishi’s wiring schematic to avoid reverse polarity).
Configuration & Testing: Restore power to the elevator (performed exclusively by certified Mitsubishi technicians) and conduct functional tests:
1. Display Calibration: Verify floor numbers, direction arrows, and status LEDs (if G24) illuminate clearly—adjust brightness via the main control board (range: 300–500 cd/m²) for optimal visibility in different lighting conditions.
2. Call Responsiveness Test: Press the up/down call buttons to confirm the board transmits signals to the main control unit immediately—no delayed or unregistered calls. Verify the call button LED illuminates to indicate a pending request.
3. Communication Validation: Run the elevator through the landing to ensure the display accurately tracks car position and direction—no mismatched data or “communication loss” alerts. For G24 variants, test service/overload alerts to confirm they display correctly.
  
  Document installation details, calibration settings, and test results in maintenance records to demonstrate compliance.

3. Routine Usage Maintenance

To preserve the LHH-1005E G21/G24’s performance and extend its lifespan, implement proactive maintenance practices tailored to landing interface components:

Daily Visual Inspections: Check the display for dimness, dead LEDs, or flickering. Verify call buttons are responsive and the panel surface is free of cracks or damage.
Weekly Cleaning: Wipe the polycarbonate panel with a soft, damp cloth and mild detergent (avoid abrasive cleaners or solvents) to remove dust, fingerprints, and smudges—maintain visibility.
Monthly Wiring Check: Inspect the wiring harness connection for looseness or corrosion—re-seat the connector if needed to prevent communication interruptions.
Quarterly Function Test: Test call buttons and display functions to confirm responsiveness and accuracy. Use the elevator’s diagnostic system to check for “LOP Display Error” codes.
Semi-Annual Firmware Update: Check for firmware updates via Mitsubishi’s official portal and install if recommended—updates enhance display stability and resolve compatibility issues.

Recommended Replacement Cycle

The service life of the Mitsubishi LHH-1005E G21/G24 LOP Display Board depends on usage intensity (daily call button presses, foot traffic), environmental conditions (humidity, dust), and maintenance quality. Based on Mitsubishi’s engineering standards and Nanjing Zhuye’s technical expertise:

1. Standard Replacement Cycle

Under normal operating conditions (regular cleaning, moderate traffic, ambient temperature -15°C to +55°C), the LHH-1005E G21/G24 should be replaced every 6–8 years. This timeframe aligns with the typical lifespan of LED modules (60,000 operating hours) and tactile button contacts, ensuring proactive replacement before display degradation or button failure impacts user experience.

2. Signs That Require Immediate Replacement

Replace the LOP display board immediately if:

Display Failures: Dim, flickering, or non-functional LEDs that make floor numbers/direction unreadable—compromises passenger safety and convenience.
Button Malfunctions: Stuck, unresponsive, or intermittently working call buttons (despite cleaning) that prevent passengers from summoning the elevator.
Physical Damage: Cracked panel, broken buttons, or water intrusion into the circuit board—risks electrical shorts or further component damage.
Communication Errors: The main control board displays recurring “LOP Communication Loss” codes—cannot be resolved by re-seating the wiring harness.
Safety Compromise: Service alerts (e.g., elevator out of order) or emergency notifications fail to display—violates EN 81-20/50 safety communication requirements.

3. Maintenance to Extend Service Life

Environmental Protection: Install a protective cover for outdoor or high-humidity landings to shield the board from moisture and dust.
Button Care: Avoid using sharp objects to press buttons; post gentle usage guidelines if high traffic causes excessive wear.
Connector Maintenance: Apply dielectric grease to the wiring harness connector annually to prevent corrosion and ensure stable signal transmission.
