Usage Guide for Elevator Pit Inspection Box KL300A004/5/6
Correct use and operation of the KL300A004/5/6 elevator pit inspection box are crucial to ensuring the safety of maintenance personnel and the elevator system. Nanjing Zhuye Elevatorparts strongly recommends that only certified elevator maintenance technicians perform operations on the inspection box, as improper use may lead to serious safety hazards such as elevator malfunctions or personal injuries. It should be noted that the pit inspection control has a lower priority than the car top inspection control in the elevator control system.
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 KL300A004/5/6 inspection box model matches the elevator model (check parameters such as voltage, current, and interface type). Consult Nanjing Zhuye Elevatorparts’ technical team immediately if there is any uncertainty about compatibility. Before entering the pit, cut off the elevator’s main power supply, lock the switch, and place a “Maintenance in Progress” warning sign at the elevator entrance and pit access. Check the pit environment to ensure no water accumulation, debris, or potential safety hazards; ensure the pit lighting is normal and the emergency stop device is functional. Put on personal protective equipment (PPE) including safety shoes, helmets, and insulated gloves, and carry necessary tools such as a multimeter and flashlight.
2. Core Operation Guidelines
After entering the pit safely, unlock the KL300A004/5/6 inspection box with the dedicated key (provided by Nanjing Zhuye Elevatorparts) and open the box door. First, check the internal indicator lights to confirm the elevator is in the standby state and no fault alarms are present. To perform inspection operations, switch the “Normal/Inspection” switch to the “Inspection” position; use the “Up/Down” buttons to control the elevator’s slow movement (speed ≤0.63m/s), and release the button to stop the elevator immediately. In case of emergency, press the red emergency stop button on the inspection box—this will cut off the elevator’s operating power supply immediately to ensure safety. After completing maintenance work, reset the emergency stop button (twist to release), switch the “Inspection” switch back to “Normal,” close the box door, and lock it firmly. Ensure the box is properly sealed to prevent moisture and dust from entering.
3. Daily Maintenance & Regular Testing
According to the “Elevator Maintenance Rules” (TSG T5002-2017), the KL300A004/5/6 inspection box should be inspected and maintained at least every 15 days. For daily maintenance, clean the box surface and surrounding areas with a dry cloth to remove dust and moisture; check if the box door seal is intact and the lock functions normally. Inspect internal wiring terminals for looseness, oxidation, or corrosion, and tighten or treat them if necessary. Every month, test the emergency stop button and inspection operation functions to ensure they are reliable; check if the indicator lights are bright and clear. Every 3 months, use a multimeter to test the electrical connections and ensure the wiring is in good condition. Keep a detailed maintenance record, which should be stored for at least 4 years in accordance with regulations.
Replacement Cycle of Elevator Pit Inspection Box KL300A004/5/6
The replacement cycle of the KL300A004/5/6 elevator pit inspection box is closely related to the operating environment and usage frequency. Under normal conditions (elevator daily operation 12-24 hours, pit environment dry and well-ventilated, no frequent water accumulation), Nanjing Zhuye Elevatorparts recommends a replacement cycle of 3-5 years. This cycle is determined based on long-term field operation data and component aging tests, fully considering the aging of internal electronic components, wear of mechanical parts, and attenuation of waterproof performance.
For elevators in harsh environments (pit with frequent water accumulation, high humidity, heavy dust, or chemical corrosion) or high-traffic areas (e.g., large shopping malls, airports with frequent maintenance operations), the replacement cycle should be shortened to 2-3 years. Harsh environments accelerate the corrosion of the box body and internal components, while high-frequency use increases the wear of switches and buttons. 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 all functions of the inspection box meet safety standards.
Replace the KL300A004/5/6 inspection box immediately if any of the following issues occur, regardless of its service life: The box body is severely cracked, deformed, or corroded, losing waterproof and protective performance; internal components (buttons, switches, indicators) fail or malfunction repeatedly and cannot be repaired; wiring terminals are severely oxidized or burned, causing poor contact or short circuits; the emergency stop function fails to trigger normally; the box cannot be locked properly, posing a safety risk of unauthorized operation.
