Usage Guide for Elevator Brake Detection Switch V4NS/3502UL
Correct installation, debugging, and maintenance of the V4NS/3502UL brake detection switch are crucial to ensuring elevator brake safety and coordinated operation with the door machine pulley system. Nanjing Zhuye Elevatorparts emphasizes that only certified elevator maintenance technicians are allowed to perform installation and replacement operations.
1. Pre-Installation Preparation
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 brake model matches the V4NS/3502UL detection switch (check parameters such as contact type, action stroke, 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 brake system power supply, lock the switch, and place a “Maintenance in Progress” warning sign at the machine room entrance. Fix the elevator car at a safe position with a hoist to ensure the brake is in a released state. Finally, prepare professional tools such as a screwdriver, wrench, multimeter, and measuring tape; clean the switch installation area and brake linkage parts, and check the door machine’s drive and driven pulleys for normal operation (abnormal pulley operation may affect door operation after brake release).
2. Installation & Wiring
If replacing the old detection switch, first take photos to record its installation position, contact direction, and wiring connections for later reference. Disconnect the wires from the old switch according to the recorded labels and remove the old switch. Take the new V4NS/3502UL switch from Nanjing Zhuye Elevatorparts, install it on the brake bracket, and fasten it firmly with screws. Adjust the switch’s action pin to ensure it is in close contact with the brake linkage—when the brake is engaged, the switch is triggered; when released, it resets. Connect the wires to the corresponding terminals strictly following the photos and the wiring diagram provided by Nanjing Zhuye—distinguish between signal wires and power wires to avoid wrong connection. After wiring, use a multimeter to test the contact on-off performance to confirm normal signal transmission.
Debugg3. Operation & Daily Maintenance
Remove the hoist fixing the car, restore the power supply, and switch the elevator to inspection mode. Operate the brake to engage and release repeatedly, observing whether the V4NS/3502UL switch is triggered accurately and sends correct signals to the control system. Check if the door machine pulley system starts door operation only when the brake is released—no misoperation is allowed. After 1 hour of stable operation, check the switch’s temperature and wiring terminals (no abnormal heat or loose wires). For daily maintenance, inspect the switch during monthly machine room patrols: Check for loose bolts, deformation of the action pin, and oxidation of contacts; clean the switch surface and action pin with a dry cloth. At the same time, check the door machine pulley system’s operation—abnormal pulley wear may cause door operation delays after brake release. Every 3 months, recheck the switch’s action stroke and contact performance; every 6 months, lubricate the switch’s moving parts with special lubricant.
Replacement Cycle of Elevator Brake Detection Switch V4NS/3502UL
The replacement cycle of the V4NS/3502UL brake detection switch is closely related to operating conditions and the frequency of door machine pulley operation. Under normal circumstances (elevator daily operation 12-24 hours, machine room environment dry and low-dust, no frequent vibration), Nanjing Zhuye Elevatorparts recommends a replacement cycle of 2-3 years. This cycle is determined based on long-term field operation data and component aging tests, fully considering the wear of the action pin, contact fatigue, and shell aging.
For elevators in high-traffic areas (e.g., large shopping malls, airports with daily operation ≥ 20 hours) or harsh environments (machine room with high humidity, heavy dust, large temperature fluctuations), the replacement cycle should be shortened to 1-1.5 years. High-frequency brake engagement and release accelerate the wear of the switch’s moving parts, while harsh environments easily cause component corrosion and jamming. 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 3-4 years, but only after inspection and confirmation by Nanjing Zhuye’s technicians that the switch’s performance and coordination with the door machine pulley system meet standards.
Replace the switch immediately if any of the following issues occur, regardless of its service life: The switch fails to trigger or is triggered incorrectly, causing the door machine pulley system to misoperate; the action pin is deformed or broken, affecting normal operation; the contacts are severely oxidized or burned, resulting in unstable signal transmission; the shell is severely corroded or damaged, losing protection performance; the switch cannot coordinate with the brake system normally, leading to frequent elevator safety alarms.
