WE 408, concentrated intelligence in a doorframe format

The WE408 is the chameleon amongst lift controls. It will perfectly adapt to the technical environment and leave no wishes unfulfilled. Be it in a narrow doorframe or conventional lift control format, it will enable your perfect integration of modules in the lift system.

CANopenLift

The WE408 is a CANopenLift controller. The easy integration of CANopenLift modules and their secure data exchange were decisive for the assertion of this bus standard in lift engineering. The system is rounded off by an automatic module recognition and its uncomplicated parameterization facility.

The control system is supplemented by a DCP and RS2323 interface, as well as I/Os for integrating conventional modules.

Intelligent

The system is virtually unlimited in scope where the software is concerned: be it as a group lift, special hospital lift or as a car lift, the WE408 will feel at home in every area. Special requirements can also be implemented.

Convenient status monitoring

The logic-based menu structure and many help texts and messages are self-explanatory and permit seamless and independent work.

Multilingual

Your customers are located all around the world. Which is why the languages German, English, Dutch, Polish and Turkish are already integrated at delivery. 

Energy-saving

The EnergyIQ option will provide you with an energy-efficient lift control technology that saves the user money while also being a good contribution to climate protection.

Fast and faultless installation

Plug & use means for you: installation cost savings. Install the preconfigured control elements, plug in the cables, start up – it couldn’t be easier!

Modular manufacture:

  • Short delivery periods
  • Consistently high quality
  • Favourable price-benefit ratio

This way of manufacturing has the advantage that basic modules can be produced in larger quantities, and then expanded with modules to meet the customer’s requirements.
