The NABTESCO MCB-1302-01 is a high-precision microcomputer control board (PCB) specifically designed for the management of automatic sliding door systems. Manufactured by Nabtesco Corporation (formerly Nabco), this control card serves as the central intelligence unit, coordinating motor drive signals, sensor inputs, and safety protocols to ensure smooth and reliable door operation.

 

Product Overview

The MCB-1302-01 is a core component of the Nabco DS series and related automatic door operators. It manages the complex acceleration and deceleration curves required for commercial door movement, preventing mechanical wear and ensuring pedestrian safety. The board is equipped with integrated logic to handle various operating modes, including “Always Open,” “Partial Open,” and “Locked,” making it a standard choice for high-traffic retail and healthcare entrances.

 

Technical Datasheet & Parameters

 

Country of Origin

The NABTESCO MCB-1302-01 is designed and manufactured in Japan.

Application Fields

• Commercial Entrances: Controlling sliding doors in shopping malls and office buildings.
• Healthcare Facilities: Managing touchless entry systems for hospitals and labs.
• Transportation Hubs: Operating heavy-duty automatic doors in airports and train stations.
• Cleanroom Environments: Interfacing with interlocking door systems to maintain air pressure.
• Accessibility Upgrades: Providing automated entry solutions compliant with ADA (Americans with Disabilities Act) standards.

 

Technical Description

Technically, the MCB-1302-01 features a high-speed 8-bit or 16-bit microprocessor that executes real-time position tracking via motor encoder feedback. It includes onboard potentiometers or digital settings for adjusting “Open Speed,” “Close Speed,” and “Brake Strength.” The board is designed with high-grade electrolytic capacitors and opto-isolated I/O ports to protect the logic circuits from electrical surges and motor back-EMF. It also features a dedicated port for the “APS” (Automatic Programming System) tool used for field calibration and fault diagnostics.

 

Usage Instructions

1. Safety First: Disconnect the main power supply before installing or servicing the MCB-1302-01. Ensure the door panel is manually secured to prevent movement.
2. Mounting: Secure the PCB into the operator housing using the original plastic standoffs to prevent short circuits against the metal chassis.
3. Wiring: Connect the motor leads, limit switches, and activation sensors (microwave or infrared) to the designated terminal blocks. Refer to the specific Nabco wiring diagram for your door model.
4. Learning Cycle: Upon power-up, initiate a “Learning Run” (often via a push-button on the board) to allow the microprocessor to detect the door’s full stroke length and weight.
5. Fine-Tuning: Use the onboard adjustment dials to set the “Hold-Open Time” and “Safety Sensitivity” to ensure the door responds correctly to pedestrians.
