Description

• Precise Control: Supports motor speed adjustment with a tolerance of ±0.1 m/s, ensuring the elevator stops accurately at floor levels (error ≤2 mm).

• Anti-Interference: Equipped with a multi-layer shielding circuit, it resists electromagnetic interference from elevator shaft electrical components—reducing signal loss by 60% compared to generic boards.

• Perfect Compatibility: Its interface layout, pin definitions, and software protocols align 100% with Otis E411’s original driver board, eliminating the need for firmware modifications or adapter wiring.

• Durability: The heat-dissipating shell keeps the board’s operating temperature within 0-60°C, extending its service life by 30% in high-temperature elevator shafts.

1. Pre-Installation Preparation:

• • Execute the Lockout-Tagout (LOTO) procedure: Shut down the elevator’s main power supply and disconnect the traction system’s power cable to prevent electrical shock.

• • Confirm compatibility: Use Nanjing Zhuye Elevator Parts’ free online lookup tool (via their official website) to verify the JAA26807BGZ1 matches your E411 elevator’s serial number and traction motor model.

• • Gather tools: Static wristband (to prevent electrostatic damage), Phillips screwdriver, anti-static bag (for storing the new board), and a digital multimeter.

2. Removal of Old Driver Board:

• • Open the elevator’s control cabinet (located in the machine room) and locate the E411 driver board (labeled “JAA26807BGZ1” on the original unit).

• • Disconnect all cables from the old board: Mark each cable with tape (noting pin numbers or port labels) to avoid misconnection—take photos of the wiring layout as a backup.

• • Remove the mounting screws securing the old board to the cabinet, then place it in an anti-static bag (do not discard it immediately; it may be needed for troubleshooting).

3. Installation of New JAA26807BGZ1 Board:

• • Take the new JAA26807BGZ1 board out of its anti-static packaging (wear the static wristband throughout this step).

• • Align the board with the mounting holes in the control cabinet and secure it with the original screws (tighten to 5-8 N·m to avoid damaging the board’s circuit).

• • Reconnect all cables according to the marked labels or photos—ensure each connector is fully inserted (you will hear a “click” for secure connections).

4. Post-Installation Testing:

• • Use the digital multimeter to check the board’s input voltage (should be 220V AC, as specified by Otis) and ensure no short circuits between ports.

• • Restore power to the control cabinet and enter the elevator’s maintenance mode (follow Otis’s E411 series operation manual).

• • Perform a no-load test: Run the elevator through 3 full cycles (from the lowest to highest floor) and check for:

• • • Stable motor speed (no sudden acceleration/deceleration)

• • • Accurate floor alignment (no gaps between the elevator car and floor)

• • • No error codes on the control cabinet’s display panel

• • If error codes appear (e.g., “E03” for signal loss), double-check cable connections or contact Nanjing Zhuye Elevator Parts’ 24/7 technical support team.

5. Daily Operation Tips:

• • Facility managers should schedule monthly checks of the control cabinet’s ventilation (ensure fans are working to prevent board overheating).

• • Avoid placing metal objects or liquids near the driver board—these can cause short circuits or corrosion.

• Normal Use (residential buildings, 8-12 hours daily operation, controlled machine room temperature): Replacement cycle of 5 to 7 years.

• High-Intensity Use (commercial buildings, 18-24 hours daily operation, frequent peak-hour traffic): Replacement cycle shortened to 3 to 4 years.

• Harsh Environments (machine rooms with high humidity >60%, dust, or temperature fluctuations >40°C): Replacement cycle of 2.5 to 3.5 years.

• The elevator frequently displays driver-related error codes (e.g., “E01” for motor control failure) that cannot be resolved by cable checks.

• Unstable operation: The elevator jerks during startup/stopping or misaligns with floors by >5 mm.

• The board’s indicator lights (on the top edge) flash abnormally (refer to Otis’s E411 manual for error light definitions).

• Physical damage: Visible corrosion on ports, burnt marks on the circuit, or loose components.

• Genuine Quality: Each board uses the same components as Otis’s original (e.g., Texas Instruments microchips) and comes with a 3-year warranty.

• Technical Support: Free firmware updates (matching Otis’s latest E411 system versions) and video tutorials for installation/testing.

• Fast Delivery: Global shipping takes 2-5 days for major markets (Europe, North America, Southeast Asia), minimizing E411 elevator downtime.
