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: Locate the existing OMD4351BHR/OMC4351BHM in the elevator car panel (secured by concealed screws or snap-on clips behind the front bezel). 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., VCC, 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 display.

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 Display: Align the Nanjing Zhuye Elevator Parts OMD4351BHR/OMC4351BHM with the mounting bracket, ensuring the display is oriented correctly (floor numbers upright and direction arrows aligned with elevator movement). Secure the display with the original screws (torque: 0.9-1.3 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 XIZI’s service software via the main controller to confirm communication—ensure no “display module communication error” codes appear. For the OMD4351BHR color variant, test color accuracy and brightness adjustment; for the OMC4351BHM, confirm monochrome visibility in different lighting conditions. 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 display’s requirements (12V DC ±10%)—using the wrong voltage can damage the screen or communication circuit.

• Anti-Static Handling: Store the display in an anti-static bag when not in use. Never touch the screen 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 XIZI’s control system.

• High-Traffic Areas: Shopping malls, airports, or high-rise office buildings (XIZI elevators operating 12+ hours daily, frequent display updates) – replace every 6-8 years. Continuous screen illumination 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: Flickering screens, dead pixels, dim or unlit segments, frozen direction indicators, or garbled text – indicating screen module failure or circuit damage.

• Communication Failures: Recurring “display communication error” codes on XIZI’s 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 XIZI Compatibility: Engineered to match XIZI’s original form factor, wiring specifications, and communication protocols, ensuring plug-and-play integration with no modifications to the car panel or control system.

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

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

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

• Fast Delivery: We maintain a large inventory of both OMD4351BHR and OMC4351BHM variants to fulfill emergency replacement orders within 24-48 hours, minimizing elevator downtime.
