Usage Guide for Elevator Leveling Sensor DAA629AS2/DAA629AT1
Correct installation, debugging, and maintenance of the DAA629AS2 and DAA629AT1 leveling sensors are crucial to ensuring elevator positioning accuracy 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 model matches the selected sensor model (DAA629AS2/DAA629AT1) by checking parameters such as installation dimensions, induction distance, and signal type. 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 shaft access door. 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 area, 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
2. Installation & Wiring
If replacing old leveling sensors, first take photos to record their installation position, induction direction, and wiring connections for later reference. Disconnect the wires from the old sensors according to the recorded labels and remove the old sensors. Take the new sensor (DAA629AS2/DAA629AT1) from Nanjing Zhuye Elevatorparts, install it on the preset bracket, and fasten it firmly with screws. Adjust the sensor’s induction distance and angle to ensure it aligns with the induction plate on the car (induction distance: 5-10mm). 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 power supply voltage and signal output to confirm normal performance.
3. Usage & 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 DAA629AS2/DAA629AT1 sensor accurately detects the car’s position and sends leveling signals. Check if the door machine pulley system starts door opening operation immediately after the elevator levels—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 sensors during monthly shaft patrols: Check for loose brackets, deviation of induction angle, and damage to the sensor surface; clean the sensor and induction plate with a dry cloth to remove dust and debris. Every 3 months, recheck the induction distance and signal output; every 6 months, test the sensor’s positioning accuracy. At the same time, check the door machine pulley system’s operation—abnormal pulley wear may cause door opening jitter after leveling.
Replacement Cycle of Elevator Leveling Sensor DAA629AS2/DAA629AT1
The replacement cycle of the DAA629AS2 and DAA629AT1 leveling sensors 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 the induction module, attenuation of signal accuracy, and shell aging.
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 operations accelerate the wear of the sensor’s induction module, while harsh environments easily cause component corrosion 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 positioning 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), affecting door opening; the sensor fails to send leveling signals or sends wrong signals, causing the door machine pulley system to misoperate; the sensor’s signal is unstable, leading to frequent elevator leveling adjustments; the shell is severely damaged or corroded, losing protective performance; the sensor’s positioning accuracy cannot be restored after adjustment.
