Usage Guide for Elevator Pit Inspection Box JX03
Correct use and operation of the JX03 elevator pit inspection box are crucial to ensuring the safety of maintenance personnel and the normal operation of the elevator. Nanjing Zhuye Elevatorparts emphasizes that only certified elevator maintenance technicians are allowed to use and maintain the inspection box to avoid safety hazards caused by improper operation.
1. Pre-Installation Preparation
First, confirm that the elevator’s MAC car lighting controller model matches the POWCV24181MH power supply (check parameters such as input voltage, output voltage, output current, and installation dimensions). Consult Nanjing Zhuye Elevatorparts’ technical team if there is any uncertainty about compatibility. Then, cut off the elevator’s main power supply and the secondary power supply for the car lighting system, lock the switch, and place a “Maintenance in Progress” warning sign at the elevator landing doors and machine room entrance. Locate the power supply installation position (usually on the car top or in the car control cabinet) and clean the area to remove dust, debris, and oil stains. Finally, prepare professional tools such as a screwdriver, wire stripper, multimeter, and insulation tester, and check that the new POWCV24181MH power supply from Nanjing Zhuye Elevatorparts is intact (no damage to the shell, no loose pins).
First, confirm that the elevator model matches the JX03 inspection box (check parameters such as installation dimensions, electrical interface, and rated voltage). Consult Nanjing Zhuye Elevatorparts’ technical team if there is any uncertainty about compatibility. Before entering the elevator pit, cut off the elevator’s main power supply, activate the inspection mode through the JX03 inspection box, and place a “Maintenance in Progress” warning sign at the elevator entrance. Check the appearance of the JX03 inspection box: ensure the shell is intact without cracks or corrosion, the door lock is flexible, and the buttons and switches are not stuck. Use a multimeter to check the internal circuit of the inspection box to confirm no short circuit or open circuit exists, and the emergency stop function is normal.
2. Operation & Usage
After entering the elevator pit, close the inspection box door and ensure it is locked to prevent dust and water from entering. When performing maintenance work, use the JX03 inspection box’s control buttons to operate the elevator car (e.g., up, down, stop) at a slow speed (usually 0.25m/s) to adjust the car position as needed. In case of emergency (e.g., personnel danger, equipment failure), immediately press the emergency stop button on the JX03 inspection box to cut off the elevator’s power supply and stop the car. During maintenance, monitor the signal indicators on the inspection box to confirm the elevator’s operating status (e.g., power on, inspection mode, fault alarm). After completing maintenance work, reset the emergency stop button, switch the JX03 inspection box back to normal mode, and check all buttons and switches to ensure they return to their original positions.
3. Daily Maintenance & Post-Use Check
After using the JX03 inspection box, clean the surface of the box with a dry cloth to remove dust and moisture. Check the wiring terminals inside the box to ensure they are tight and free of oxidation; if there is oxidation, clean it with a wire brush in time. For daily maintenance, inspect the JX03 inspection box during monthly elevator pit patrols: Check if the shell is corroded or damaged, the door seal is intact (to ensure waterproof and dustproof performance), and the buttons and switches are flexible. Every 3 months, use a multimeter to test the electrical performance of the inspection box (e.g., circuit on-off, signal transmission); every 6 months, conduct a comprehensive inspection of the internal components, replacing any damaged buttons, switches, or wires in time with genuine parts from Nanjing Zhuye Elevatorparts.
Replacement Cycle of Elevator Pit Inspection Box JX03
The replacement cycle of the JX03 elevator pit inspection box is closely related to the working environment of the elevator pit and usage frequency. Under normal circumstances (elevator daily operation 12-24 hours, pit environment dry and low-dust, no frequent water accumulation), Nanjing Zhuye Elevatorparts recommends a replacement cycle of 4-5 years. This cycle is determined based on long-term field operation data and component aging tests, fully considering the wear of buttons and switches, corrosion of the shell, and aging of internal electrical components.
For elevators in harsh environments (elevator pit with frequent water accumulation, high humidity, heavy dust, or large temperature fluctuations) or high-traffic areas (e.g., large shopping malls, airports with frequent maintenance), the replacement cycle should be shortened to 2-3 years. Harsh environments accelerate the corrosion of the shell and the damage of internal components, while high-frequency use increases the wear of buttons and switches. For low-usage elevators (e.g., villa elevators, small office buildings with daily operation time < 8 hours) in stable environments, the cycle can be extended to 5-6 years, but only after inspection and confirmation by Nanjing Zhuye’s technicians that the inspection box’s performance and safety protection function meet standards.
Replace the inspection box immediately if any of the following issues occur, regardless of its service life: The shell is severely corroded or damaged, losing waterproof and dustproof performance; buttons or switches are stuck or invalid, affecting normal operation; internal circuits are short-circuited or open-circuited, causing the emergency stop function to fail; the inspection box cannot correctly transmit signals, leading to abnormal elevator operation or fault alarms; the wiring terminals are severely burned or oxidized, and cannot be repaired.
