Usage Guide for Elevator Leveling Sensor SLA30-Z15NK-F20DS
Correct installation, debugging, and maintenance of the SLA30-Z15NK-F20DS leveling sensor are crucial to ensuring precise elevator leveling 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 control system model matches the SLA30-Z15NK-F20DS sensor (check parameters such as detection distance, output signal type, 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 control system power supply, lock the switch, and place a “Maintenance in Progress” warning sign at the machine room entrance and landing. Use a hoist to fix the elevator car at a safe position to expose the sensor installation area. Finally, prepare professional tools such as a screwdriver, wrench, multimeter, and measuring tape; clean the installation position on the car or shaft, and check the door machine’s drive and driven pulleys for normal operation (abnormal pulley operation may affect door opening after leveling).
2. Installation & Wiring
If replacing the old sensor, first take photos to record its installation position, height, and wiring connections for later reference. Disconnect the wires from the old sensor according to the recorded labels and remove the old sensor. Take the new SLA30-Z15NK-F20DS sensor from Nanjing Zhuye Elevatorparts, install it on the preset bracket (ensure the detection surface is aligned with the induction plate on the shaft), and fasten it firmly with screws. The distance between the sensor and the induction plate should be 5-10mm (adjust according to Nanjing Zhuye’s technical parameters). Connect the wires to the corresponding terminals strictly following the photos and the wiring diagram provided by Nanjing Zhuye—distinguish between power wires, signal wires, and ground wires to avoid wrong connection. After wiring, use a multimeter to test the sensor’s output signal to confirm normal power supply and 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 elevator to run up and down, observing whether the elevator stops precisely at each landing (leveling deviation should be within ±2mm). Check if the door machine pulley system starts door opening immediately after leveling—no delay or misoperation is allowed. After 1 hour of stable operation, check the sensor’s temperature and wiring terminals (no abnormal heat or loose wires). For daily maintenance, inspect the sensor during monthly shaft patrols: Check for looseness, damage, or contamination on the sensor surface; confirm the induction plate is clean and not deformed; clean the sensor and induction plate with a dry cloth. At the same time, check the door machine pulley system’s operation—abnormal pulley wear may cause door opening faults after leveling. Every 3 months, recheck the sensor’s detection accuracy and output signal; every 6 months, inspect the wiring harness for aging and replace if necessary.
Replacement Cycle of Elevator Leveling Sensor SLA30-Z15NK-F20DS
The replacement cycle of the SLA30-Z15NK-F20DS leveling sensor is closely related to operating conditions and the frequency of door machine pulley operation. Under normal circumstances (elevator daily operation 12-24 hours, shaft 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 inductive elements and the attenuation of signal transmission performance.
For elevators in high-traffic areas (e.g., large shopping malls, airports with daily operation ≥ 20 hours) or harsh environments (shaft with high humidity, heavy dust, large temperature fluctuations), the replacement cycle should be shortened to 1-1.5 years. High-frequency leveling and door opening accelerate the aging of sensor components, while harsh environments easily cause sensor contamination and signal interference. 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 sensor’s detection accuracy and coordination with the door machine pulley system meet standards.
Replace the sensor immediately if any of the following issues occur, regardless of its service life: The elevator has obvious leveling deviation (exceeding ±5mm) and cannot be adjusted; the sensor has no output signal or the signal is unstable, causing the elevator to fail to stop at the landing or open the door; the sensor shell is cracked, damaged, or the waterproof performance fails; the sensor’s response speed is significantly reduced, causing delayed door opening after leveling; the sensor cannot coordinate with the door machine pulley system normally, leading to door opening faults.
