XIO Elevator 18.5KW Inverter SMART 100-LR-4018-H3: Efficient & Stable Drive Core for Elevators

Proper Usage Methods of XIO Elevator 18.5KW Inverter SMART 100-LR-4018-H3

1. Installation & Parameter Configuration

• First, cut off the elevator’s main power supply and secure the work area to ensure safety. Install the inverter in a well-ventilated, dry, and dust-free position in the machine room, avoiding direct sunlight, high-temperature heat sources, and water splashing. Ensure there is at least 15cm of heat dissipation space around the inverter to prevent overheating.
• Firmly fix the inverter on the mounting bracket using matching bolts, ensuring the installation surface is flat and stable to reduce vibration during operation. The tightening torque should comply with XIO’s technical requirements (typically 8–12 N·m) to avoid loosening due to long-term machine room vibration.
• Correct wiring connection: In accordance with the wiring diagram provided by Nanjing Zhuye Elevatorparts and XIO, connect the inverter’s input terminals (L1, L2, L3) to the three-phase power supply, and output terminals (U, V, W) to the elevator traction motor. Connect the control signal wires (elevator speed command, emergency stop signal, etc.) to the corresponding control terminals of the inverter. Ensure all wiring is tight and reliable, the wire cross-section meets the current requirements (≥4mm² for power wires), and the insulation layer is intact to prevent short circuits or poor contact. Pay special attention to the phase sequence of input and output wires to avoid motor reverse rotation.
• Parameter configuration & commissioning: After wiring, power on the inverter and enter the parameter setting interface. According to the XIO elevator’s technical requirements and the traction motor’s parameters (rated voltage, rated current, rated speed), configure key parameters such as base frequency, rated current, acceleration time, and deceleration time. After configuration, operate the elevator in inspection mode to test: verify that the elevator starts smoothly without obvious impact, runs stably at rated speed, and stops accurately at each floor. Monitor the inverter’s operating data (output current, temperature, voltage) through the display panel to ensure all indicators are within the normal range. If there is abnormal vibration, noise, or fault code, recheck the parameter settings and wiring and adjust promptly.

2. Daily Operation & Routine Inspection

• During daily elevator operation, monitor the inverter’s operating status through the display panel. Pay attention to fault codes, output frequency, current, and temperature. Abnormal phenomena such as frequent fault alarms, excessive temperature (exceeding 60℃), or unstable current indicate potential faults in the inverter or peripheral circuits.
• Conduct weekly visual inspections and cleaning: Cut off the power supply first, then use a dry, lint-free cloth or a professional dust blower to clean the inverter’s surface and heat dissipation vents, removing dust and debris to ensure unobstructed heat dissipation. Check the inverter’s shell, wiring terminals, and connecting wires for cracks, deformation, looseness, or oxidation, and retighten loose terminals or replace damaged wires in a timely manner.
• Periodically check the cooling system: Inspect the inverter’s cooling fan (if equipped) for normal operation, ensuring there is no abnormal noise or jamming. Check the heat sink for accumulated dust; clean it with a soft brush if necessary to maintain heat dissipation efficiency.

3. Regular Maintenance

• Every 3 months, conduct a comprehensive inspection of the inverter’s wiring connections and insulation performance. Use a multimeter to detect the insulation resistance between the power terminals and the ground to ensure it meets the standard requirements (≥1MΩ). Check the tightness of all terminals and retighten if there is any looseness due to vibration.
• Every 6 months, perform a full performance test: Verify the inverter’s output voltage stability, speed regulation accuracy, and energy consumption indicators. Recheck and calibrate key parameters to ensure they are consistent with the elevator’s operating requirements. Test the built-in protection functions (simulate overcurrent, overtemperature scenarios) to confirm they can be triggered accurately and reliably.
• Annually, arrange professional maintenance with Nanjing Zhuye Elevatorparts’ technical team. Disassemble the inverter’s shell to inspect internal components (including power modules, capacitors, and control circuit boards), remove internal dust with professional tools, and replace aging components (such as electrolytic capacitors) if necessary. This ensures the long-term stable operation of the inverter and maintains its performance at the factory standard.

Recommended Replacement Cycle of XIO Elevator 18.5KW Inverter SMART 100-LR-4018-H3

1. Standard Replacement Cycle

2. Scenario-Based Cycle Adjustment

• Harsh Operating Environments: For elevators in high-humidity coastal regions, high-dust construction sites, unventilated high-temperature machine rooms, or areas with strong electromagnetic interference (e.g., near high-voltage equipment), the replacement cycle should be shortened to 5–7 years. Harsh conditions accelerate the aging of power modules, corrosion of circuit boards, and damage to cooling systems, significantly reducing the inverter’s reliability and service life.
• Low-Frequency Use Scenarios: For elevators with low usage frequency (e.g., villa elevators, small office buildings with less than 3,000 monthly rides) and stable machine room environments, the replacement cycle can be appropriately extended to 10–12 years—provided a professional inspection by Nanjing Zhuye Elevatorparts confirms that the inverter’s output stability, insulation performance, and key component status are intact.

3. Immediate Replacement Conditions

• The inverter frequently triggers irreversible fault codes (e.g., persistent overcurrent, overvoltage, or overtemperature alarms) that cannot be resolved after maintenance and parameter adjustment.
• The power module is damaged, leading to abnormal output voltage, unstable motor operation, or failure to start the elevator.
• Internal components (such as capacitors) show obvious bulging, leakage, or burning phenomena, posing potential safety hazards.
• The inverter fails the annual performance test, and key indicators (speed regulation accuracy, energy efficiency, protection function reliability) cannot be restored to the standard range even after maintenance.
