Elevator Buffer Switch I88-SU1Z: Premium Safety Component from Nanjing Zhuye Elevatorparts
The Elevator Buffer Switch I88-SU1Z is a critical electromechanical safety component designed for elevator buffer system protection, mainly used to detect the actuation state of elevator buffers and trigger emergency stop signals to prevent secondary accidents when the elevator overtravels. As a trusted supplier, Nanjing Zhuye Elevatorparts provides genuine I88-SU1Z buffer switches that fully comply with international standards such as EN ISO 13849-1 and EN IEC 60947-5-1, as well as national standards GB7588 and GB/T18775. It features IP65 protection grade, 1NO/1NC contact configuration, manual reset function, and a durable metal enclosure, widely compatible with mainstream elevator brands and suitable for various buffer types, including polyurethane and spring buffers.
Nanjing Zhuye Elevatorparts adheres to strict quality control, and each I88-SU1Z buffer switch undergoes rigorous pre-delivery testing, including mechanical life testing (minimum 50,000 operations), high-low temperature (-25℃ to 85℃) resistance, insulation verification (≥2MΩ with 500V megohmmeter), and contact reliability detection. It adopts an adjustable roller actuator, M20×1.5 screw terminals supporting 0.75-2.5mm² cables, and anti-corrosion coating for harsh hoistway environments. The compact design fits narrow buffer installation spaces, and all products are backed by a one-year warranty and professional technical support from Nanjing Zhuye Elevatorparts.
Usage Guide for Elevator Buffer Switch I88-SU1Z
As a core part of the elevator safety loop, the I88-SU1Z buffer switch requires standard installation, debugging, and regular inspection to ensure elevator operation safety. Nanjing Zhuye Elevatorparts strongly recommends operations be performed by certified technicians. Before installation, confirm the switch matches the elevator’s buffer model and control system. For detailed diagrams and parameters, refer to Nanjing Zhuye Elevatorparts’ product manual or contact our technical team.
1. Pre-Installation Preparation
First, cut off the elevator’s main power and lock the switch to avoid accidental startup, then move the car to a safe position to expose the buffer installation area. Prepare tools: screwdriver, torque wrench, multimeter, wire strippers, insulation tape, and level ruler. Clean the installation surface on the buffer bracket to remove dust, oil, and rust. Inspect the I88-SU1Z switch for enclosure damage, loose terminals, or actuator wear, and use a multimeter to test contact continuity to ensure no internal faults.
2. Installation & Wiring
Fix the I88-SU1Z switch on the buffer bracket according to EN 50047 standards, adjust the position to align the roller with the buffer plunger, ensuring the actuating angle is 30-60° for sensitive triggering. Tighten screws to the specified torque to prevent vibration-induced loosening. Follow Nanjing Zhuye Elevatorparts’ guidelines to wire the switch to the control cabinet: connect power and signal wires to M20 terminals, ensure firm connections, and insulate joints. Separate power and signal wires to reduce interference, and confirm the contact configuration matches the control system requirements before finishing wiring.
3. Debugging & Daily Inspection
After installation, restore power and start debugging. Manually actuate the buffer to verify the switch triggers the emergency stop signal reliably, and the elevator stops immediately without malfunction. Test the manual reset function to ensure it resumes normal operation after reset. For daily inspection, follow TSG regulations and Nanjing Zhuye Elevatorparts’ recommendations: conduct semi-monthly checks on the switch’s enclosure and terminals, quarterly contact continuity tests, and regular cleaning of the actuator to maintain sensitivity.
Replacement Cycle of Elevator Buffer Switch I88-SU1Z
The replacement cycle of the I88-SU1Z switch depends on usage frequency, environment, and maintenance. Under normal conditions—12-24 hours daily operation, regular maintenance, and dry hoistways—Nanjing Zhuye Elevatorparts recommends replacement every 4-6 years, considering contact wear, enclosure aging, and actuator degradation over time.
For high-traffic elevators (airports, subway stations) or harsh environments (high humidity, dust), shorten the cycle to 2-4 years to avoid safety risks. For low-usage elevators (villas, small offices), proper maintenance can extend the cycle to 6-8 years. Switches used for over 5 years require semi-annual comprehensive inspections by Nanjing Zhuye Elevatorparts technicians to assess replacement needs early.
Replace immediately if: The switch fails to trigger or reset; the enclosure is cracked or corroded (reducing IP65 protection); contact is poor; the actuator is stuck; it causes frequent elevator safety loop faults; or it fails annual safety inspections. Always use genuine I88-SU1Z switches from Nanjing Zhuye Elevatorparts to ensure compatibility and safety.
