Description

1. Professional Selection & Installation: Installation must be performed by certified elevator technicians with expertise in KONE systems. Before starting, shut off the elevator’s main power supply and follow lockout-tagout protocols to eliminate electrical hazards. Select the correct model based on the elevator’s functional requirements (refer to KONE’s official compatibility list): KM713700G71 for basic setups, KM713720G71 for commercial applications, KM713730G71 for smart/remote-monitored elevators. Align the communication board with the designated mounting slots in the control cabinet and secure it with corrosion-resistant screws to prevent vibration-induced loosening. Connect the wiring harnesses to the main controller, peripheral devices, and power supply—adhere to KONE’s official service manual for precise pin connections and protocol settings. After installation, power on the system and verify physical connections (no loose wires or reversed polarity).

2. Protocol Configuration & Calibration: Use KONE-approved diagnostic software to configure communication protocols (CANopen/Modbus) and network parameters (baud rate, address, data format) to match the elevator’s control system. For KM713730G71, set up remote communication parameters (IP address, port number) to enable connectivity with KONE’s monitoring platform. Calibrate signal transmission thresholds to ensure stable data exchange between components—Nanjing Zhuye Elevator Parts recommends conducting a communication loop test to verify data integrity (no packet loss or corruption).

3. Routine Inspection & Maintenance: Maintenance teams should conduct regular inspections semi-annually. Visually check for physical damage (burnt components, swollen capacitors, loose connectors) and signs of overheating (discolored circuit traces, abnormal heat emission). Inspect wiring connections for tightness, corrosion, or fraying—especially in high-humidity environments. Clean the board’s surface and connectors with a dry, anti-static cloth to remove dust and debris (dust accumulation can cause short circuits or signal interference). Use professional testing equipment to monitor communication speed, signal strength, and error rates, ensuring alignment with KONE’s specified ranges. Document inspection results, including model-specific performance data, to track trends and identify potential issues early.

4. Troubleshooting Operational Issues: If the elevator experiences communication errors (e.g., “no response from display” or “remote monitoring failure”), unresponsive peripherals, or data synchronization glitches, troubleshooting the KM7137 board is essential. First, verify the power supply to the board and check wiring connections for damage or looseness—poor electrical contact is a common cause of communication failures. Use KONE’s diagnostic software to retrieve error codes (e.g., protocol mismatch, signal loss) and test communication links between the board and connected devices. For model-specific issues (e.g., KM713730G71’s remote connectivity failures), inspect network settings and firewall configurations. Visually examine the PCB for physical damage (burnt chips, cracked traces) which indicates immediate replacement. For persistent problems like intermittent signal drops or uncorrectable protocol errors, contact Nanjing Zhuye Elevator Parts’ technical support team for expert guidance tailored to KONE KM7137 series systems.

5. Safety Precautions: Never handle the communication board without proper electrical and KONE elevator system training. Do not attempt maintenance while the elevator is in operation; always isolate power and use lockout-tagout procedures. Avoid electrostatic discharge damage by wearing an anti-static wristband during installation or inspection. Do not modify the board’s circuitry, protocol settings, or component configurations—such alterations compromise system compatibility, void the warranty, and may lead to operational failures.

1. Standard Replacement Cycle: Under normal operating conditions (8-12 hours of daily use in medium-traffic buildings), the KM7137 series has an average service life of 8-10 years. Nanjing Zhuye Elevator Parts recommends a comprehensive performance audit every 4 years to assess communication stability, protocol compatibility, and component aging.

2. Factors Shortening Lifespan: High-traffic environments (airports, malls, transit hubs) with 14+ hours of daily operation or frequent data transmission (especially KM713730G71 in remote-monitored elevators) may require replacement every 6-7 years. Harsh operating conditions such as high humidity, extreme temperatures (below -10℃ or above 45℃), poor ventilation in control cabinets, or frequent power surges can accelerate circuit degradation. Poor maintenance (infrequent cleaning, ignored communication errors) also shortens service life by causing cumulative damage to communication chips.

3. Key Signs for Replacement: Replace the communication board immediately if you observe persistent communication errors, unresponsive peripherals, failed protocol synchronization, physical damage (burnt components, cracked PCB), or if the board has exceeded the 10-year maximum service life. Delaying replacement can lead to elevator downtime, loss of remote monitoring capabilities, and increased maintenance costs.

4. Replacement Best Practices: Always use a genuine KONE Elevator Communication Board KM713720G71/KM713730G71/KM713700G71 from a trusted supplier like Nanjing Zhuye Elevator Parts to ensure full compatibility with KONE systems. Before replacement, isolate the elevator power, document existing wiring configurations and protocol settings, and back up the main controller’s program. Install the new board following KONE’s guidelines, reconnect wiring accurately, and reconfigure protocols to match the elevator’s specifications. Conduct comprehensive tests—including communication loop verification, peripheral connectivity checks, and remote monitoring (if applicable)—before returning the elevator to service. Dispose of the old board in accordance with local electronic waste regulations.
