Elevator Landing Door Car Bypass Control Box P207013B000G02

Model No.:P207013B000G02

An elevator landing door and car door bypass control box is a device used in elevator maintenance or emergency scenarios. It allows the temporary bypass of door lock circuit detection, ensuring the elevator can operate safely under specific conditions, such as fault troubleshooting or repair. Below is a detailed explanation of its features and functions:

Function Overview

1. Bypass Functionality:
   • Temporarily bypasses the detection of landing or car door locks when they are faulty or not fully closed.
   • Enables low-speed elevator movement in emergency or maintenance situations.
2. Safety Assurance:
   • Limits elevator operation speed and range when the bypass is active.
   • Used alongside other safety devices, such as inspection mode switches, to ensure personnel safety.
3. Control Features:
   • Allows manual activation and deactivation of the bypass function.
   • May include signal indicators (e.g., lights or buzzers) to display the bypass status.
4. Compatibility:
   • Designed to work with various elevator brands and models.
   • Can integrate with elevator control systems to provide real-time feedback.

Key Components

1. Control Switch:
   • A mechanical or electronic switch for manually activating or deactivating the bypass function.
2. Indicators or Displays:
   • Signal lights or screens to show the device status (e.g., bypass enabled, disabled, or fault detected).
3. Connection Ports:
   • Interfaces with the elevator control cabinet and electrical circuits to connect to the door lock circuit.
4. Safety Circuits:
   • Prevents unintended operations or prolonged bypass activation, with features like automatic reset.

Applications

1. Maintenance and Repair:
   • Assists technicians in moving the elevator to a convenient position when the door system requires servicing.
2. Troubleshooting:
   • Provides a temporary solution for faulty door locks while maintaining limited elevator functionality.
3. Emergency Evacuation:
   • Allows the elevator to be moved to specific floors during emergencies (e.g., fire or earthquake) to evacuate passengers.

Key Features

1. Safety and Reliability:
   • Operations are restricted under bypass mode (e.g., speed and range limitations) to prevent safety risks.
2. Portability:
   • Often designed as a portable device, making it easy for technicians to carry and use.
3. Ease of Use:
   • Simple interface, suitable for quick deployment in emergency or maintenance scenarios.
4. Standards Compliance:
   • Conforms to elevator safety standards (e.g., EN 81-20/50 or equivalent local regulations) to ensure the device’s safety and functionality.

Precautions

1. Restricted Use:
   • Only qualified technicians should operate the bypass function. It is not intended for regular user operation.
2. Reset After Use:
   • The bypass function must be deactivated after maintenance or troubleshooting is completed, and the door lock system should be verified to be operational.
3. Regular Inspection:
   • The control box and related circuits should be periodically inspected to ensure proper functionality and avoid degradation over time.
