Description

1. Safety Preparation: Before installation, shut off the elevator’s main power supply and disconnect the car control panel power. Implement LOTO (Lockout/Tagout) procedures to prevent electrical hazards. Wear an anti-static wristband and insulating gloves to protect sensitive electronic components from static damage and injury.

2. Remove the Old Display Board: Locate the existing KM51275572G02/G01 board in the elevator car panel (secured by concealed screws or snap-on clips behind the front panel). Use a plastic pry tool to gently remove the bezel (avoid metal tools to prevent scratches). Take detailed photos of the wiring connections—note terminal labels (e.g., 24V+, GND, DATA+, DATA-) and cable colors to ensure correct reconnection. Disconnect the wiring harness gently, then remove the fixing screws or release the clips to detach the old board.

3. Prepare the Mounting Area: Clean the mounting bracket and car panel cutout with a dry, lint-free cloth to remove dust, debris, or residual adhesive. Inspect the wiring harness for fraying, insulation damage, or bent pins (replace if necessary) to ensure reliable electrical contact.

4. Install the New Board: Align the Nanjing Zhuye Elevator Parts KM51275572G02/G01 board with the mounting bracket, ensuring the display is oriented correctly (floor numbers upright and direction arrows aligned with elevator movement). Secure the board with the original screws (torque: 0.8-1.2 N·m) or snap it into place until the clips lock firmly. Reconnect the wiring harness according to the photos, matching each wire to the correct terminal—push connectors until they click to avoid loose connections.

5. Test and Calibrate: Restore power to the car control panel and elevator. Verify the display initializes properly: check that floor numbers, direction indicators, and door status lights update in real time as the elevator travels. Access KONE’s LCE Tools software via the main controller to confirm communication—ensure no “display module error” codes (e.g., E33, E34) appear. For the G02 variant, test adaptive brightness by adjusting ambient light in the car (e.g., turning on/off ceiling lights) and confirm the display adjusts automatically. Run 15+ floor cycles to validate consistent performance with no flickering, frozen screens, or delayed updates.

• Voltage Compatibility: Ensure the car control panel’s power supply matches the board’s requirements (24V DC ±10%)—using the wrong voltage can damage the LED modules or communication circuit.

• Anti-Static Handling: Store the board in an anti-static bag when not in use. Never touch the LED modules or exposed circuit board with bare hands, as static electricity can cause permanent component failure.

• Physical Care: Avoid striking or scraping the tempered glass panel. Clean the display with a soft, lint-free cloth dampened with distilled water (no harsh chemicals or abrasive materials) to maintain clarity.

• Wiring Protection: Route the wiring harness away from sharp edges or moving parts in the car panel. Do not pull, twist, or bend the harness excessively, as this can disrupt communication with KONE’s control system.

• High-Traffic Areas: Shopping malls, airports, or high-rise office buildings (KONE elevators operating 12+ hours daily, frequent display updates) – replace every 6-8 years. Continuous LED operation and power cycling accelerate component aging.

• Medium-Traffic Areas: Residential buildings, hotels, or mid-rise offices (8-10 hours daily usage) – replace every 8-10 years.

• Low-Traffic Areas: Villas, industrial facilities, or low-occupancy buildings (4-6 hours daily usage) – replace every 10-12 years, with annual functionality and visibility inspections.

• Display Defects: Dim or dead LED segments, flickering floor numbers, frozen direction indicators, or garbled text – indicating LED module failure or circuit damage.

• Communication Failures: Recurring “display communication error” codes on KONE’s LCE controller that persist after wiring checks and harness replacement.

• Physical Damage: Cracked glass panel, loose mounting (causing rattling during elevator movement), or water damage (from car roof leaks).

• Power Irregularities: The display fails to power on, shuts off intermittently, or resets unexpectedly – signs of power supply module degradation.

• Synchronization Issues: Floor numbers or door status do not match the elevator’s actual position (e.g., display shows “door closed” when doors are open) – indicating protocol communication failure.

• 1:1 KONE Compatibility: Engineered to match KONE’s original form factor, wiring specifications, and communication protocols, ensuring plug-and-play integration with no modifications to the car panel or control system.

• KONE-Grade Durability: Tempered glass panels and industrial-grade LED modules deliver the same resilience as KONE’s OEM boards, withstanding heavy usage and minor impacts.

• Rigorous Quality Assurance: 100% pre-delivery testing, including display functionality, communication sync with KONE’s LCE system, and environmental stress trials (temperature, humidity, vibration).

• Expert KONE Support: Our team of certified technicians specializes in KONE elevator interfaces, providing professional guidance on installation, calibration, and troubleshooting via phone or email.

• Fast Delivery: We maintain a large inventory of both KM51275572G01 and G02 variants to fulfill emergency replacement orders within 24-48 hours, minimizing elevator downtime.
