Usage Guide for Elevator Pit Inspection Box 13508674-A

Correct use, installation, and maintenance of the 13508674-A elevator pit inspection box are crucial to ensuring the safety of elevator pit maintenance and the coordinated operation with the door machine pulley system. Nanjing Zhuye Elevatorparts emphasizes that only certified elevator maintenance technicians are allowed to perform installation, operation, and replacement operations.

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 13508674-A pit inspection box (check parameters such as installation dimensions, interface type, and control function). Consult Nanjing Zhuye Elevatorparts’ technical team if there is any uncertainty about compatibility. Then, cut off the elevator’s main power supply and control system power supply, lock the switch, and place a “Maintenance in Progress” warning sign at the elevator entrance and pit access door. Enter the pit after ensuring the pit is dry and free of debris, and use a bracket to fix the inspection box installation position. Finally, prepare professional tools such as a screwdriver, wrench, multimeter, and wire stripper; clean the installation area, and check the door machine’s drive and driven pulleys for normal operation (record any abnormalities for subsequent maintenance).

2. Installation & Wiring

If replacing the old pit inspection box, first take photos to record its installation position, wiring connections, and fixed method for later reference. Disconnect the wiring harness from the old inspection box according to the recorded labels and remove the old inspection box. Take the new 13508674-A inspection box from Nanjing Zhuye Elevatorparts, install it on the preset bracket, and fasten it firmly with screws (ensure the box door can be opened and closed smoothly). Connect the wiring harness to the corresponding terminals strictly following the photos and the wiring diagram provided by Nanjing Zhuye—distinguish between power wires, control wires, and signal wires to avoid wrong connection. After wiring, use a multimeter to test the power supply voltage and signal transmission to confirm normal performance. Install the waterproof seal on the box door to ensure the inspection box’s waterproof performance.

3. Usage & Daily Maintenance

Before using the inspection box for maintenance, confirm the elevator is in the maintenance state and the main power supply is cut off. Open the inspection box door, turn on the pit lighting switch, and check the display module for normal operation. Use the emergency stop button in the box to test the elevator’s emergency stop function—ensure the elevator stops immediately and the door machine pulley system stops operating. During maintenance, use the inspection control button to coordinate the door machine pulley system’s door opening and closing operation. After maintenance, reset all switches in the box, close the door tightly, and restore the power supply. For daily maintenance, inspect the inspection box during monthly pit patrols: Check if the box body is intact, the door seal is tight, and there is no water or dust inside; confirm the buttons and switches are sensitive and the wiring terminals are tight. Clean the box surface and internal components with a dry cloth. At the same time, check the door machine pulley system’s operation—abnormal pulley operation can be recorded and fed back through the inspection box’s monitoring function.

Replacement Cycle of Elevator Pit Inspection Box 13508674-A

The replacement cycle of the 13508674-A pit inspection box is closely related to the pit environment and maintenance frequency, and is also associated with the door machine pulley system’s operation status. Under normal circumstances (pit environment dry and low-dust, daily elevator operation 12-24 hours, regular maintenance), Nanjing Zhuye Elevatorparts recommends a replacement cycle of 5-6 years. This cycle is determined based on long-term field operation data and component aging tests, fully considering the aging of the box body, buttons, and internal control modules.

For elevators in harsh pit environments (high humidity, heavy dust, frequent water accumulation) or high-traffic areas (e.g., large shopping malls, airports with frequent maintenance), the replacement cycle should be shortened to 3-4 years. Harsh environments easily cause corrosion of the box body and internal components, while frequent use accelerates button wear. For low-usage elevators (e.g., villa elevators, small office buildings with daily operation time < 8 hours) in stable pit environments, the cycle can be extended to 6-8 years, but only after inspection and confirmation by Nanjing Zhuye’s technicians that the inspection box’s performance and coordination with the door machine pulley system meet standards.

Replace the inspection box immediately if any of the following issues occur, regardless of its service life: The box body is severely corroded or damaged, losing waterproof and protective performance; buttons or switches are stuck, insensitive, or invalid, affecting maintenance operations; the display module fails to work, unable to monitor the elevator status; internal components are burned or short-circuited, causing frequent elevator fault alarms; the inspection box cannot send control signals to the door machine pulley system, affecting door opening and closing during maintenance.
