Usage Guide for Elevator Contact Switch AZ-051
Correct installation, wiring, and debugging of the AZ-051 elevator contact switch are crucial to ensuring the safe operation of elevators. Nanjing Zhuye Elevatorparts strongly recommends that only certified elevator electrical technicians perform installation and maintenance, as improper operation may lead to serious safety hazards such as elevator misoperation or unexpected stops.
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 AZ-051 contact switch is compatible with the elevator model (check parameters such as voltage, current, contact type, and installation dimensions). Consult Nanjing Zhuye Elevatorparts’ technical team immediately if there is any uncertainty about compatibility. Then, cut off the elevator’s main power supply and control cabinet power supply, lock the switch, and place a “Maintenance in Progress” warning sign at the elevator entrance. Wait 15-30 minutes to discharge the internal capacitor of the control system, and use a multimeter to confirm no residual voltage exists. Finally, prepare professional tools including a screwdriver, wire stripper, multimeter, and insulated gloves, and clean the switch installation area to remove dust, debris, and oil stains.
2. Installation & Wiring
Locate the original switch position in the control cabinet or door system and take photos to record the wiring direction and terminal connections for future reference. Disconnect the wiring of the old switch according to the labels and remove the old switch. Take the new AZ-051 contact switch from Nanjing Zhuye Elevatorparts, install it on the bracket, and fix it firmly with screws—ensure the switch is installed horizontally without tilt. Connect the wires to the corresponding terminals strictly following the wiring diagram provided by Nanjing Zhuye and the recorded photos, ensuring firm connections and correct polarity (reverse connection may damage the switch or control system). After wiring, use a multimeter to test the on-off performance of the switch, confirming that the contact is reliable when closed and the insulation is good when open.
3. Daily Maintenance & Post-Operation Testing
Restore the power supply and switch the elevator to inspection mode. Test the corresponding system (door control, emergency stop, etc.) to ensure the switch works normally—for example, the elevator door should not close when the door interlock switch is open, and the emergency stop function should be triggered immediately when the switch is activated. After 1 hour of stable operation, check the switch’s working status to ensure no abnormal heating or loose connections. For daily maintenance, inspect the switch during monthly patrols: check for cracks or damage on the shell, confirm the wiring terminals are tight and free of oxidation, and clean the switch surface with a dry cloth. Every 3 months, use a multimeter to recheck the contact resistance; every 6 months, inspect the mechanical structure of the switch to ensure flexible operation without jamming.
Replacement Cycle of Elevator Contact Switch AZ-051
The replacement cycle of the AZ-051 elevator contact switch is closely related to operating frequency and working environment. Under normal conditions (elevator daily operation 12-24 hours, control cabinet temperature 0℃-40℃, no frequent overload or 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 contacts, aging of internal springs, and attenuation of insulation performance.
For elevators in high-traffic areas (e.g., large shopping malls, airports with daily operation ≥20 hours) or harsh environments (high humidity, heavy dust, large temperature fluctuations), the replacement cycle should be shortened to 1-1.5 years. High-frequency switch operations accelerate contact wear, while harsh environments cause component corrosion and reduce insulation performance. 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 meets safety standards.
Replace the AZ-051 contact switch immediately if any of the following issues occur, regardless of its service life: The switch contacts are severely worn or burned, leading to poor contact or frequent circuit disconnection; the shell is cracked or damaged, losing protection performance; the switch fails to trigger or reset normally, causing elevator system faults; the contact resistance exceeds 100mΩ (uncorrectable); the switch is contaminated by corrosive substances and cannot be cleaned, affecting insulation performance.
