Description

1. Pre-Installation Safety: Shut down the elevator’s main power supply and activate lockout-tagout (LOTO) procedures to prevent accidental electrical shock. Access the car display area—typically mounted on the elevator car ceiling or front panel—and ensure the work area is clean, dry, and well-lit. Wear insulated gloves and safety glasses as additional precautions.

2. Remove the Old Display Board: Carefully detach the decorative bezel or cover surrounding the old board using a non-abrasive tool to avoid surface damage. Disconnect the wiring harnesses from the back of the old board, taking detailed photos or labeling each connector to ensure correct reattachment. Remove the mounting screws or clips securing the old board and gently extract it from the housing.

3. Install the New Board: Unpack the new LHD-601A from Nanjing Zhuye Elevator Parts and inspect it for shipping damage (such as cracked panels or loose wires). Align the board with the mounting points in the car display area and secure it firmly with the original screws or clips. Reconnect each wiring harness to its corresponding port—ensure connectors are fully seated to prevent signal loss or flickering displays.

4. Testing and Calibration: Restore power to the elevator and switch to inspection mode. Verify that the display board lights up immediately, showing clear floor numbers and direction indicators as the elevator travels between floors. Test emergency functions by activating the elevator’s test mode (per Mitsubishi’s technical manual) to confirm alerts display correctly. Adjust brightness via the elevator’s control panel if needed to suit passenger comfort and environmental lighting.

5. Routine Maintenance: During regular elevator inspections, wipe the display panel with a soft, dry cloth to remove dust and fingerprints. Inspect wiring for fraying, corrosion, or loose connections, and ensure the decorative bezel remains securely attached. Avoid using harsh chemicals or abrasive materials, as these can scratch the panel or damage the LED modules. Periodically check for software updates (if applicable) to maintain optimal performance.

• Standard Usage (Residential Buildings): For elevators operating 8–10 hours daily with moderate traffic, replace the display board every 48–60 months. Low-traffic residential elevators may extend this cycle to 60 months if no performance issues (such as dim LEDs, intermittent flickering, or incomplete displays) are detected.

• High Usage (Commercial/Industrial): Elevators in shopping malls, office towers, or airports—operating 12+ hours daily with heavy foot traffic—require more frequent replacement. Nanjing Zhuye advises replacing the board every 36–48 months to prevent sudden failures that can confuse passengers or disrupt elevator operation.

• Signs of Immediate Replacement: Replace the LHD-601A immediately if you notice: dim or non-functional LEDs, distorted floor numbers, unresponsive direction indicators, persistent flickering, visible damage (cracked panels or burnt circuits), or failure to display emergency alerts. Ignoring these signs can lead to passenger inconvenience, safety concerns, or non-compliance with building safety codes.

• OEM-Grade Compatibility: Each board is engineered to match Mitsubishi’s original design, ensuring seamless integration with existing elevator systems without modifications or software adjustments.

• Superior Build Quality: High-grade materials and strict quality control guarantee resistance to wear, dust, and temperature changes, extending the board’s service life even in harsh operating environments.

• Expert Technical Support: Nanjing Zhuye’s team of engineers provides professional guidance for installation, troubleshooting, and calibration, helping resolve issues quickly and minimizing downtime.

• Global Logistics Efficiency: With a well-established supply chain, Nanjing Zhuye ensures timely delivery of replacement parts to customers worldwide, ensuring maintenance teams can complete repairs without unnecessary delays.
