Description

1. Safety Preparation: Prior to installation, shut off the elevator’s main power supply and secure the switch with a safety tag to prevent accidental activation. Equip yourself with insulated gloves and an anti-static wristband to protect against electric shock and electrostatic damage to the board’s sensitive electronics. Ensure the LOP housing—typically located in elevator lobbies or inside the elevator car—is clean, dry, and free of dust, debris, or loose wires.

2. Old Board Removal: Carefully remove the front cover of the LOP housing using a suitable screwdriver, following Mitsubishi’s recommended disassembly procedures to avoid damaging the fixture. Disconnect the wiring harnesses from the existing display board: take detailed photographs or label each connector with its corresponding position and color code, as incorrect reconnection can lead to malfunctions. Remove the mounting screws that secure the old board in place, then gently extract the board from the housing, taking care not to bend or damage the circuits.

3. New Board Installation: Align Nanjing Zhuye’s P366718B000G01 LOP display board with the mounting slots in the LOP housing. Secure the board firmly using the original screws or the provided replacement screws to prevent vibration during elevator operation—loose mounting can cause connection issues or physical damage to the board. Reconnect each wiring harness according to your labels or photographs, ensuring each connector is fully inserted and locked into place. Loose connections often result in dim displays, unresponsive buttons, or complete system failure.

4. Wiring & Function Verification: Cross-check all connections against the Mitsubishi elevator’s wiring diagram or Nanjing Zhuye’s technical documentation to confirm accuracy. Ensure power cables and signal wires are properly routed, insulated, and separated to avoid short circuits. For touch-enabled models, verify that the touch sensors align precisely with the button markers on the acrylic panel. No additional configuration is needed for basic operation, as the board is pre-programmed to sync automatically with Mitsubishi’s control system.

5. Power-On & Operational Testing: Restore the elevator’s main power supply. The display board should power on automatically, displaying the current floor number and default indicators. Conduct a comprehensive functional test: press each floor button to confirm responsive feedback, monitor direction indicators to ensure they update correctly as the elevator moves, and test emergency message display by activating the elevator’s test mode (e.g., fire alarm or overload simulation). Ensure the display is clearly visible from all angles within the lobby or elevator car. If any issues arise—such as flickering screens, incorrect floor readings, or unresponsive controls—immediately power off the system, recheck all wiring connections, and consult Nanjing Zhuye’s technical support team for troubleshooting assistance.

1. Standard Usage Environments: For residential buildings, small offices, or low-traffic facilities with 300-600 elevator trips per day, the recommended replacement cycle is 7-9 years. Conduct annual inspections to check for signs of wear, including dimmed LEDs, faded indicator symbols, intermittent button or touch unresponsiveness, or loose connectors.

2. High-Traffic Commercial Spaces: Elevators in shopping malls, hotels, airports, or office towers with over 1200 trips per day experience frequent user interactions, vibration, and power cycles, which accelerate component aging. Replace the display board every 5-6 years. Perform semi-annual inspections to monitor display brightness, button/touch sensitivity, connector integrity, and overall functionality.

3. Harsh Operating Conditions: Elevators in industrial areas (exposed to dust, heavy vibration, or extreme temperatures), coastal regions (high humidity and salt air), or locations with unstable power grids require more frequent replacement. Replace the board every 4-5 years. Conduct quarterly inspections to check for corrosion, moisture ingress, LED burnout, or circuit damage caused by power surges.

4. Immediate Replacement Scenarios: Replace the P366718B000G01 LOP display board immediately if it exhibits persistent issues such as blank screens, incorrect floor readings, unresponsive buttons or touch controls, or physical damage (e.g., cracked panels, water exposure, or burnt components). A faulty display board can confuse passengers, delay emergency responses, or hinder accessibility for individuals with disabilities, making urgent replacement critical for safety and compliance.
