Elevator CAN Repeater G-381 V1.2-100K & G-1003: Signal Enhancement Core from Nanjing Zhuye Elevatorparts

Elevator CAN Repeaters G-381 V1.2-100K and G-1003 are critical signal transmission components designed for elevator CAN bus communication systems, specifically engineered to amplify, regenerate, and extend CAN bus signals. As the “signal booster” of elevator communication networks, they solve signal attenuation and interference issues in long-distance or complex elevator systems, ensuring stable data transmission between the main control system, sensors, actuators, and other components (e.g., LOP display boards, door controllers, weighing devices). Exclusively supplied by Nanjing Zhuye Elevatorparts (a professional and trusted distributor of high-quality elevator electrical components), the Elevator CAN Repeater G-381 V1.2-100K & G-1003 fully comply with international CAN bus standards (ISO 11898) and elevator safety regulations (EN 81-20, GB 7588). Featuring high signal amplification precision, strong anti-interference ability, and wide compatibility (supporting 100Kbps baud rate for G-381 V1.2-100K), these repeaters are widely applied in high-rise buildings, commercial complexes, industrial elevators, and other scenarios requiring long-distance CAN bus communication worldwide.

Nanjing Zhuye Elevatorparts adheres to the core philosophy of “quality first, stability paramount” and implements strict quality control over the G-381 V1.2-100K and G-1003 CAN repeaters. Each unit undergoes multi-stage pre-delivery inspections, including signal amplification performance testing, anti-interference verification, baud rate compatibility detection, and long-term stability trials. The products adopt advanced signal regeneration technology, a flame-retardant ABS shell (UL94 V0 rating), and a sealed circuit design: the signal regeneration technology ensures that attenuated CAN signals are restored to standard amplitude and waveform without distortion; the flame-retardant shell and IP54 dustproof and waterproof rating adapt to the humid, dusty, and vibrating environment in elevator shafts and control cabinets; the optimized circuit layout enhances resistance to electromagnetic interference from elevator traction systems and other high-power components. Their standardized CAN bus interfaces (DB9 or terminal block) and compact structural design are tailored to most mainstream elevator CAN bus systems, eliminating the need for complex modifications and enabling quick installation.

Step-by-Step Usage Guide for Elevator CAN Repeater G-381 V1.2-100K & G-1003

To ensure the reliable operation of the elevator CAN bus communication system and extend the service life of the G-381 V1.2-100K and G-1003 repeaters, follow the professional guidelines provided by Nanjing Zhuye Elevatorparts for installation, parameter configuration, and maintenance:

1. Professional Installation & Wiring

Installation must be performed by certified elevator technicians familiar with CAN bus systems. Prior to installation, confirm the compatibility of the repeater model (G-381 V1.2-100K/G-1003) with the target elevator’s CAN bus baud rate and interface type using the detailed compatibility manual provided by Nanjing Zhuye Elevatorparts. The steps are as follows:

Safety Preparation: Cut off the elevator’s main power supply and the dedicated power supply of the CAN bus system. Locate the installation position (usually in the control cabinet or along the CAN bus trunk in the shaft) and clean the area to remove dust, oil stains, and debris that may affect heat dissipation and insulation.
Repeater Installation: Fix the G-381 V1.2-100K/G-1003 repeater to the dedicated mounting bracket using high-strength screws provided by Nanjing Zhuye Elevatorparts. Ensure the repeater is installed vertically (tilt angle ≤ 3°) and maintain a 10–15mm heat dissipation gap between adjacent components. Avoid installing it near high-power components (e.g., contactors, inverters) to reduce electromagnetic interference.
Wiring Operation: According to the CAN bus wiring diagram, connect the “CAN-H” and “CAN-L” terminals of the repeater to the upstream and downstream CAN bus lines (note the positive and negative polarity to avoid reverse connection). Connect the repeater’s power terminal to the specified DC power supply (rated voltage: 24VDC for both models). Fasten the wiring terminals with a torque wrench to ensure tight contact, and use shielding cables for CAN bus connections (ground the shielding layer properly as guided by Nanjing Zhuye Elevatorparts to enhance anti-interference ability).
Post-Installation Testing: Restore the power supply and switch the elevator to inspection mode. Use a CAN bus analyzer to detect signal parameters (amplitude, waveform, baud rate) at the input and output ends of the repeater, ensuring the signal is amplified and regenerated normally without distortion. Operate the elevator’s key functions (e.g., leveling, door opening/closing) to verify stable communication between all CAN bus-connected components. If there is signal distortion, communication interruption, or error codes related to the CAN bus, recheck the installation and wiring immediately.

2. Parameter Configuration & Routine Inspection

Scientific parameter configuration and regular inspections are key to ensuring optimal performance of the G-381 V1.2-100K and G-1003 repeaters:

Parameter Configuration: The G-381 V1.2-100K is pre-configured with a 100Kbps baud rate (matching most elevator CAN bus systems), while the G-1003 supports multi-baud rate adjustment (via DIP switches). Adjust the baud rate according to the elevator’s CAN bus requirements (refer to the manual provided by Nanjing Zhuye Elevatorparts) to ensure consistency with the entire communication network.
Daily Visual Inspection: During control cabinet and shaft patrols, check the external condition of the repeater. Ensure the shell is free of cracks, deformation, or discoloration (a sign of overheating); the power indicator and communication status indicator (if equipped) are working normally; the wiring terminals are tight without looseness, oxidation, or burning marks.
Weekly Functional Check: Use a CAN bus analyzer to monitor the repeater’s working status, including input/output signal strength and error frame rate (should be ≤ 0.1%). Verify that the elevator’s CAN bus communication remains stable during peak operation periods. Record the test data for future comparison and fault diagnosis.

3. Regular Maintenance Schedule

Systematic maintenance can effectively extend the service life of the G-381 V1.2-100K and G-1003 CAN repeaters. Follow Nanjing Zhuye Elevatorparts’ recommended maintenance plan:

Quarterly Maintenance: Disconnect the power supply and remove the repeater from the mounting bracket. Thoroughly clean the shell, terminals, and ventilation holes with a professional electrical cleaner to remove dust and oxide. Inspect the wiring for aging or cracking (replace with shielded cables if necessary) and recheck all connections for tightness. Reinstall the repeater and verify that parameters remain unchanged.
Semi-Annual Performance Test: Conduct a comprehensive performance test, including signal amplification gain, anti-interference ability, and baud rate stability. Simulate harsh working conditions (e.g., voltage fluctuation, electromagnetic interference) using professional equipment to verify the repeater’s stable operation. For high-rise elevators or those in industrial environments with strong interference, increase the test frequency to once every 3 months.
Annual Professional Overhaul: Arrange a professional inspection with Nanjing Zhuye Elevatorparts’ certified technical team. Update the repeater’s internal firmware (if applicable) to optimize compatibility and performance. Replace aging repeaters with genuine G-381 V1.2-100K/G-1003 units. Inspect the entire CAN bus system (including cables, connectors, terminating resistors) and replace damaged components to ensure coordinated operation with the repeaters.

Recommended Replacement Cycle for Elevator CAN Repeater G-381 V1.2-100K & G-1003

As core signal transmission components bearing long-term electrical loads, frequent signal processing, and environmental erosion, the G-381 V1.2-100K and G-1003 CAN repeaters have a specified service life. Timely replacement is critical to avoiding faults such as reduced signal amplification capacity, frequent communication errors, or complete signal interruption—issues that may lead to abnormal elevator operation, failure of safety-related components, or even elevator shutdown.

1. Standard Replacement Cycle

Under normal operating conditions (elevator daily operation time 12–24 hours, stable CAN bus communication load, environment temperature -10–60℃, humidity 10%–95%), the recommended replacement cycle for both G-381 V1.2-100K and G-1003 CAN repeaters is 4–5 years. This cycle is determined based on Nanjing Zhuye Elevatorparts’ long-term field data, component aging tests, and global user feedback.

2. Adjustments for Special Scenarios

Harsh Environments: For elevators in high-humidity coastal areas (salt spray corrosion), high-dust construction sites, or industrial zones with strong electromagnetic interference (e.g., near welding equipment, high-voltage lines), the replacement cycle should be shortened to 2–3 years. Harsh conditions accelerate circuit board aging, component corrosion, and signal processing performance degradation.
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 communication environments (no frequent electrical interference), the replacement cycle can be extended to 5–6 years—only if Nanjing Zhuye’s professional inspection confirms the repeaters’ signal amplification performance, anti-interference ability, and component integrity are intact.

3. Immediate Replacement Conditions

Replace the G-381 V1.2-100K/G-1003 CAN repeater immediately if any of the following issues occur, regardless of service life:

Frequent CAN bus communication errors (error frame rate > 1%) cannot be eliminated through debugging, leading to abnormal operation of elevator components (e.g., incorrect floor display, unresponsive door control).
The repeater fails to amplify signals normally—signal amplitude at the output end is less than 50% of the standard value, resulting in communication interruption between remote components and the main control system.
The repeater’s shell is severely cracked, deformed, or corroded; internal components show signs of burning (e.g., marks, odor), and the repeater cannot work normally even after maintenance.
The repeater has no power output or communication signal (confirmed by professional testing), and the fault cannot be resolved by checking the power supply and wiring, affecting the elevator’s normal operation and safety protection functions.
