Linak Control Box KC33D for Electric Medical Bed and Adjustable Furniture Actuator System

Introduction

The Linak KC33D is an intelligent control box from the OpenBus series . It serves as the central control unit for electric actuator systems commonly found in medical and care equipment think hospital beds, nursing beds, operating tables, and rehabilitation devices. Its primary job is to coordinate actuator movements, manage power distribution, and oversee safety functions, making it a key component for ensuring smooth and safe device operation.

The control box is built with a compact, lightweight design and comes in two power variants 120W and 190W to suit different application needs. It sits within LINAK's K-series product line and is equipped with OpenBus technology, allowing it to handle multiple hand controls or other OpenBus accessories for applications that require more advanced features.

Advantages

• Up to five channels
• Dedicated emergency stop switch channel (for LINAK 's next generation ES2)
• Two OpenBus ports for connecting two hand controllers or one hand controller and one accessory
• Unique OpenBus safety feature to prevent accidental lever movement.
• Dedicated safety movement modes can be implemented in applications using specialized software.
• Excellent cable management, clean and tangle-free. Multiple flexible installation options.

Installation

1. Select an appropriate mounting location. The control box supports multiple installation options and is compatible with a range of mounting brackets.

2. Attach the appropriate mounting bracket to the application frame using screws.

3. Slide the control box onto the bracket until you hear a distinct click, this indicates the box is securely locked in place.

4. Important: The KC33D should be installed in a position that allows any accumulated water to drain away.

5. Connect the power supply (230–240 VAC, 50/60 Hz) to the control box.

6. Connect actuators to the desired channels (up to five channels available).

7. Connect hand controls or other OpenBus™ accessories to the two OpenBus ports.

8. If required, connect an ES2 emergency stop switch to the dedicated ES port.

Attention

• Ensure proper prioritisation of emergency functions. In an OpenBus system with the KC33D, the ES2 emergency stop must never be given a higher priority than CPR (Cardiopulmonary Resuscitation) functions—CPR must always have the highest priority to ensure patient safety.

• Use only genuine LINAK accessories. To ensure safe and reliable operation, only use LINAK-approved actuators, hand controls, cables, and accessories with the KC33D control box.

• Observe the duty cycle. The KC33D has a 10% duty cycle, supporting continuous operation for up to 2 minutes before entering automatic sleep protection. Extended operation beyond this limit may trigger thermal protection.
