When it comes to modern machine control systems, touch systems come to mind. But there are other ways – and sometimes even better. A new, illuminated membrane keypad with particularly intuitive menu navigation was created for the redesign of a docker winder control panel.
THE REQUIREMENT:
The previous solution consisted of a robust switch panel with a carrier plate, mechanical buttons, potentiometers and a front foil. This unit was getting on in years and needed a complete overhaul.
It was important to the customer:
- Large, clearly visible buttons
- simple, guided operation
- the continued use of the existing machine interface
The operator should be clearly guided through the menu to prevent operating errors.
OUR SOLUTION:
We first presented our technical capabilities and the SideLED demo board at an on-site meeting. The first ideas for a modern redesign of the control system were already being developed. After further joint workshops, it was clear that the new operating unit would be a fully illuminated membrane keypad with a disappearing effect.
The result is a membrane keypad on a printed circuit board with LEDs and integrated electronic components. A key requirement was that automatic and manual mode could not be activated at the same time. We developed our own software for this in combination with intelligent lighting effects. Operation is now clear and guided:
After selecting a mode, only the associated functions are illuminated and visible. All other buttons remain “invisible”. The disappearing effect means that symbols only appear when they are really relevant.
To ensure that the new keypad can continue to communicate with the existing machine interface, we worked with the customer to program the appropriate communication protocol for the existing frequency inverter.
The result is a modern, clear and fail-safe operating panel without touch, but with clear advantages for the user. The new membrane keypad combines intuitive user guidance, robust technology and a modern look. A successful example of how existing machines can be further developed with intelligent input systems.
Our video below shows the intuitive operation through intelligent user guidance in action:
- After starting, two modes initially appear: automatic and manual mode
- Select mode and further functions become visible
- Non-relevant functions remain invisible due to the “disappearing effect”
- Programmed software controls the menu navigation in real time.
