Arkel ARCODE 4B26A, 400V, 26A Integrated Lift Control Unit (ILCU)

The Arkel ARCODE 4B26A is an Integrated Lift Control Unit (ILCU) designed for three-phase 400V systems, providing a nominal output current of 26 A and a maximum output current of 52 A (for periods under 6 seconds). This specific model is typically matched with lift motors rated up to 11 kW (15 HP).

As an integrated device, ARCODE combines the VVVF inverter, the primary control board, and the emergency evacuation system into a single, compact, and synchronized package.

The Arkel ARCODE 4B26A (400V 26A) ILCU is optimized for 11 kW motors. It offers superior performance through Direct Landing technology, full control synchronization, and is ideal for both modernization and space-saving Machine-Room-Less (MRL) projects.

Frequently Asked Questions (FAQs)

Q1: What is the primary benefit of the ARCODE’s integrated design?

The primary benefit lies in combining the VVVF drive, the control board, and the emergency evacuation system into a single unit. This full synchronization between the controller and the motor drive eliminates compatibility issues, minimizes installation time, reduces the complexity of wiring, and saves significant space, which is critical for Machine-Room-Less (MRL) applications.

Q2: How does the ARCODE 4B26A support modernization projects?

The ARCODE 4B26A supports modernization by offering universal motor compatibility for both existing Asynchronous (Geared) and new Synchronous (Gearless) machines. Modernization companies can initially replace the old control panel with the ARCODE and an ENCI (Incremental Encoder Card) to immediately gain comfort and efficiency. The motor upgrade can be performed later, simply by swapping the ENCI card for the ENCA (Absolute Encoder Card) to support the new synchronous motor.

Q3: What are the standard limits for the ARCODE 4B26A and how can I increase them?

The ARCODE 4B26A ships with a Basic License which limits operational speed to 1.6 m/s and the maximum number of floors to 16. If your project requires higher performance, the system is scalable. You can purchase and install optional hardware license dongles (MDA or HDA) to increase capacity up to 4 m/s and 64 floors.

Q4: How does ARCODE handle emergency evacuation during a power failure?

The ARCODE has an integrated evacuation system. In case of a mains power failure, the unit automatically uses an external backup power supply—either a 60-120VDC battery bank or a 1-phase 220VAC UPS connected to the L1 and L3 terminals—to drive the motor. The evacuation function moves the car to the nearest floor or a specific pre-determined evacuation floor to safely release passengers. This feature is supported only for closed-loop operation.
