Step-by-Step Usage Guide for Elevator Leveling Sensor DAA629F/F1/F2/F3/Q1

To maximize the positioning accuracy and service life of the Elevator Leveling Sensor DAA629F/F1/F2/F3/Q1, and to ensure the safe and stable operation of the elevator, strictly follow the professional guidelines provided by Nanjing Zhuye Elevatorparts for installation, debugging, and maintenance:

1. Professional Selection & Installation

Installation must be conducted by certified elevator technicians proficient in elevator control systems. Prior to installation, refer to the compatibility manual provided by Nanjing Zhuye Elevatorparts to select the appropriate model (DAA629F/F1/F2/F3/Q1) based on the elevator’s control system type, speed, and leveling requirements. The installation steps are as follows:

Safety Preparation: Cut off the elevator’s main power supply and lock the power switch to prevent accidental power-on. Operate the elevator car to the middle floor and fix it with mechanical supports. Clean the sensor mounting position (usually on the car roof or guide rail bracket) to remove dust, oil stains, and debris that may affect sensing accuracy.
Sensor Installation: Fix the DAA629 series sensor to the dedicated mounting bracket using bolts provided by Nanjing Zhuye Elevatorparts. Ensure the sensor’s sensing surface is aligned with the leveling plate (installed on the guide rail) and the distance between them is within the standard range (5–15mm, subject to specific model specifications). Adjust the sensor’s horizontal and vertical positions to avoid deviation affecting signal detection.
Wiring Operation: In accordance with the elevator control system wiring diagram and the DAA629 series user manual, connect the sensor’s signal cables (normally open/normally closed contacts) and power cables (DC 24V, standard for most models) to the corresponding terminals of the main controller. Use shielded cables for signal transmission to enhance anti-interference performance. Confirm correct wiring polarity and tight connections; label the cables clearly for future maintenance.

2. Debugging & Calibration

Debugging and calibration are crucial to ensure the sensor’s positioning accuracy. Follow these steps with reference to Nanjing Zhuye Elevatorparts’ technical guidelines:

Initial Debugging: Restore the elevator’s power supply and switch to inspection mode. Operate the elevator car to move up and down slowly, observing the sensor’s signal output status via the controller’s display. Confirm that the sensor outputs a stable signal when the car approaches the leveling plate and stops outputting when it leaves.
Leveling Calibration: Adjust the sensor’s position slightly to ensure the elevator car stops precisely at the floor level. Test the leveling accuracy at multiple floors (especially the top and bottom floors) and record the deviation. If the deviation exceeds the standard, re-calibrate the sensor’s position or adjust the controller’s leveling parameters until the deviation is within ≤ 2mm.
Function Test: Conduct 10 consecutive up-and-down operation tests to verify that the sensor transmits stable signals at each floor, and the elevator stops accurately without obvious vibration or deviation. Test the sensor’s anti-interference performance by simulating electromagnetic interference in the shaft to ensure no false signals or signal loss.

3. Daily Operation & Routine Maintenance

Regular inspection and maintenance are essential to ensure the long-term stable operation of the DAA629 series sensor. Maintenance personnel should integrate the following checks into their daily patrol routines:

Daily Visual Inspection: During shaft patrols, check the sensor’s external condition. Ensure the metal housing is free of deformation, corrosion, or damage; the sensing surface is clean without dust or scratches; the wiring is intact without aging, wear, or loose connections. Observe the elevator’s leveling status—abnormal phenomena such as obvious deviation or repeated adjustment when stopping may indicate sensor faults.
Weekly Signal Test: Use a multimeter to detect the sensor’s signal output status, confirming that the normally open/normally closed contacts switch correctly when the car passes the leveling plate. Check the sensor’s power supply voltage to ensure it is within the rated range (DC 24V ± 10%).
Monthly Cleaning & Calibration: Cut off the power supply and clean the sensor’s sensing surface and the leveling plate with a soft, dry cloth to remove dust and debris. Re-check the sensor’s mounting position and the distance to the leveling plate, adjusting if there is any deviation. Conduct a secondary leveling calibration to ensure the accuracy meets the requirements.

Recommended Replacement Cycle for Elevator Leveling Sensor DAA629F/F1/F2/F3/Q1

As a core positioning component enduring long-term environmental erosion (humidity, dust, vibration in the shaft), frequent signal transmission, and component aging, the DAA629 series leveling sensor has a specified service life. Timely replacement is critical to avoiding faults such as inaccurate positioning, delayed signal transmission, or signal loss—issues that may cause elevator overshoot, undershoot, or repeated adjustment when stopping, affecting passenger safety and ride comfort.

1. Standard Replacement Cycle

Under normal operating conditions (elevator daily operation time 12–24 hours, daily leveling times ≥ 1500, environment temperature -20–60℃, humidity 10%–95%), the recommended replacement cycle for the DAA629F/F1/F2/F3/Q1 is 5–6 years. This cycle is determined based on Nanjing Zhuye Elevatorparts’ long-term field operation data, sensor component aging tests, and global user feedback on elevator positioning systems.

2. Adjustments for Special Scenarios

Harsh Environments & High-Traffic Scenarios: For elevators in high-humidity coastal areas (salt spray corrosion), shaft pits prone to water accumulation, or high-traffic locations (e.g., airports, shopping malls) with daily leveling times ≥ 3000, the replacement cycle should be shortened to 3–4 years. Harsh conditions and frequent use accelerate the aging of sensing elements and housing corrosion, significantly reducing the sensor’s reliability.
Low-Frequency Use Scenarios: For elevators with low usage frequency (e.g., villa elevators, small office buildings with daily operation time < 8 hours) and stable shaft environments, the replacement cycle can be extended to 6–7 years—only if Nanjing Zhuye Elevatorparts’ professional technicians conduct an inspection and confirm that the sensor’s positioning accuracy, signal stability, and anti-interference capability meet the original factory standards.

3. Immediate Replacement Conditions

Replace the DAA629 series sensor immediately if any of the following issues occur, regardless of its service life:

The sensor’s positioning accuracy exceeds 5mm, and the elevator has obvious overshoot or undershoot when stopping, which cannot be corrected by calibration.
Signal transmission is unstable or lost, causing the elevator to fail to stop at the target floor, or to repeatedly adjust after stopping, affecting normal use.
The sensor’s housing is severely corroded or damaged, the sensing surface is scratched or contaminated (cannot be cleaned), or the internal components are faulty (no signal output).
Professional testing confirms that the sensor’s response time exceeds 0.3s, failing to meet the elevator’s leveling control requirements.
