STA 21 AUTOMATIC SLIDING DOOR OPERATOR
Automatic opening of light to medium weight linear sliding doors.
The STA 21 has been modified to suit a lower budget whilst still meeting the requirements of light to medium doors in heavy-duty applications.
Utilising the same Swiss-engineered intelligence system enables the interactive exchange of information between the control system and the various activation and safety devices. The majority of the STA 21 components are shared with the system 20, which is well proven in global markets but fitted with smaller, lighter electrical motors and a specially modified PLC.
Mechanics
The absence of noise is the most striking feature of our automatic doors and is achieved with a combination of:
- acoustically decoupled, hardened running tracks (replaceable)
- running carriage with hardened nylon wheels with sealed bearings and compensation for structural tolerance and adjustable attachment to door leaves
- motor and guide pulleys with sealed bearings
- low momentum toothed belt drive for minimum wear and low acoustic impact
Electronics
- interactive communication between components to monitor and enhance performance, safety and security
- malfunction potential is greatly reduced by the drive monitoring ability
- self learning processor with active automatic adjustment for optimum operation is the heart of the drive system which provides ongoing quality performance
- record BDE-D mode switch, with graphic display, enhanced by background lighting with menu-LED navigation, full diagnostics and programming capability
