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 SH-GS3W4 leveling sensor (check parameters such as working voltage, 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 the power supply of the leveling system, lock the switch, and place a “Maintenance in Progress” warning sign at the machine room entrance and landing doors. Use a hoist to fix the elevator car at a middle floor to ensure a safe operation space. Finally, prepare professional tools such as a screwdriver, wrench, multimeter, and level ruler, and clean the sensor installation position (on the car or guide rail) to remove dust, rust, and debris.
2. Installation & Calibration
If replacing the old sensor, first take photos to record its installation position, wiring direction, and terminal connections for later reference. Disconnect the wires from the old sensor according to the labels and remove the old sensor. Take the new SH-GS3W4 leveling sensor from Nanjing Zhuye Elevatorparts, install it on the preset position with screws, and ensure it is vertical and aligned with the leveling plate on the guide rail (use a level ruler for calibration). Connect the wires to the corresponding terminals strictly following the photos and the wiring diagram provided by Nanjing Zhuye: Connect the power line to the “DC24V” terminal, the signal line to the “SIG” terminal, and the ground line to the “GND” terminal. After wiring, calibrate the sensor: Operate the elevator to each floor, adjust the sensor’s height so that the signal is triggered accurately when the car is level with the floor; use a multimeter to check the signal output, which should be stable without interference.
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 all floors repeatedly, checking the leveling accuracy at each floor: The gap between the car floor and the landing floor should not exceed 1mm, and there should be no obvious vibration when stopping. After 2 hours of stable operation, stop the elevator and inspect the sensor again to confirm no loose wiring, abnormal heating, or signal interference. For daily maintenance, inspect the sensor during monthly shaft patrols: Check if the shell is damaged, the lens is dirty, and the wiring terminals are tight; clean the lens with a dry cloth to ensure accurate detection. Every 3 months, use a multimeter to test the power supply and signal output; every 6 months, re-calibrate the sensor’s position to ensure consistent leveling accuracy.
Replacement Cycle of Elevator Leveling Sensor SH-GS3W4
The replacement cycle of the SH-GS3W4 elevator leveling sensor is closely related to the operating environment and usage frequency. 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, optical component aging tests, and electronic circuit performance assessments, fully considering the attenuation of positioning accuracy and the wear of mechanical components.
For elevators in high-traffic areas (e.g., large shopping malls, airports with daily operation ≥ 20 hours) or harsh environments (e.g., high humidity, heavy dust, strong electromagnetic interference, frequent vibration), the replacement cycle should be shortened to 1-1.5 years. High-frequency operation accelerates the aging of optical and electronic components, while harsh environments affect signal stability and sensor durability. 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 positioning accuracy and signal stability meet safety standards.
Replace the sensor immediately if any of the following issues occur, regardless of its service life: The elevator has obvious leveling deviation (gap exceeding 3mm) that cannot be corrected by calibration; the sensor signal is unstable or lost, causing the elevator to overshoot, undershoot, or fail to stop; the sensor lens is severely scratched or fogged, affecting detection; the shell is severely damaged, deformed, or corroded; the sensor has no signal output or abnormal heating during operation; the elevator frequently reports leveling system faults confirmed to be caused by the sensor.
