Description

1. Safety Preparation: Before installation, shut off the elevator’s main power supply and disconnect the traction machine power. Implement LOTO (Lockout/Tagout) procedures to prevent accidental brake activation. Wear insulating gloves, safety glasses, and protective footwear to avoid electrical hazards and mechanical injury.

2. Remove the Old Switch: Locate the existing X-10GD-B micro switch on the brake assembly (typically secured by 2-4 screws). Take detailed photos of the wiring connections, lever orientation, and mounting position – note terminal labels (Common, Normally Open, Normally Closed) and cable colors to ensure correct reconnection. Disconnect the wires gently (use a terminal puller if needed) and loosen the fixing screws to remove the old switch.

3. Prepare the Mounting Area: Clean the mounting surface with a soft brush or lint-free cloth to remove dust, oil, or debris. Inspect the brake lever or actuator that contacts the switch – ensure it is free of wear or deformation (replace if necessary to ensure proper switch activation).

4. Install the New Switch: Align the Nanjing Zhuye Elevator Parts X-10GD-B micro switch with the mounting holes, ensuring the lever actuator is positioned to make contact with the brake’s mechanical component (typically a cam or pin). Secure the switch with the original screws (torque: 0.8-1.2 N·m) to prevent vibration-induced misalignment. Reconnect the wires according to the photos, matching each wire to the correct terminal – use crimp connectors or terminal blocks to ensure tight, insulated connections (avoid loose wiring that can cause signal errors).

5. Test and Verify: Restore power to the traction machine (but not the elevator main power). Manually operate the brake lever to simulate engagement and disengagement: check that the switch clicks clearly (indicating contact activation) and that the controller receives the correct signal (verify via diagnostic mode). Conduct a dynamic test: restore elevator power, run the elevator through 10+ floor cycles, and confirm the brake engages/disengages as intended, with no error codes related to “brake switch malfunction.”

• Voltage/Current Compatibility: Confirm the elevator’s control circuit matches the switch’s ratings (AC 250V 10A / DC 30V 10A) before installation – exceeding these limits can damage the switch contacts.

• Lever Alignment: Ensure the brake’s mechanical actuator makes full contact with the switch lever (stroke: 1-3mm) without over-pressing (which can damage the spring mechanism). Adjust the mounting position if necessary.

• Regular Cleaning: Clean the switch housing and lever every 6 months with a dry cloth to remove dust or oil buildup. Avoid using water or harsh chemicals, as these can corrode contacts or damage the housing.

• Avoid Mechanical Damage: Do not bend the switch lever or strike the housing, as this can disrupt the snap-action mechanism and affect signal accuracy.

• High-Traffic Areas: Shopping malls, airports, or office buildings (12+ hours daily operation, 1,000+ brake cycles per day) – replace every 2-3 years. Frequent mechanical contact and electrical switching accelerate contact wear.

• Medium-Traffic Areas: Residential buildings, hotels, or small offices (8-10 hours daily, 500-1,000 brake cycles per day) – replace every 3-5 years.

• Low-Traffic Areas: Villas, industrial facilities, or low-occupancy buildings (4-6 hours daily, per day) – replace every 5-7 years, with semi-annual inspections.

• Brake Fault Codes: Recurring errors like “brake switch signal loss,” “brake not engaged,” or “unsafe movement detected” that persist after checking wiring and alignment.

• Intermittent Brake Issues: Elevator fails to start (due to false “brake engaged” signals) or stops unexpectedly (due to false “brake disengaged” signals) – indicators of contact bounce or switch failure.

• Physical Damage: Cracked housing, bent lever, or corroded terminals – which can cause signal interruption or short circuits.

• Reduced Response: The switch lever feels stiff or fails to snap back into position, or contact resistance exceeds 100mΩ (measured with a multimeter).

• Perfect Compatibility: Engineered to match Omron’s original specifications, ensuring seamless integration with existing elevator brake systems without modifications.

• Safety-Centric Design: Industrial-grade materials and precision manufacturing deliver accurate signal transmission and long-term reliability in harsh operating environments.

• Rigorous Quality Assurance: 100% pre-delivery testing, including contact resistance validation and mechanical endurance trials, to meet global safety standards.

• Expert Technical Support: Our team of engineers provides professional guidance on installation, alignment, and troubleshooting via phone or email, ensuring a smooth user experience.

• Fast Delivery: We maintain a large inventory of X-10GD-B micro switches to fulfill emergency replacement orders within 24-48 hours, minimizing elevator downtime.
