The TST FUZ2-A is a single-phase door control unit from FEIG ELECTRONIC with an integrated frequency converter, designed for balanced sectional doors and small high-speed doors in industrial and commercial settings. It drives 3-phase asynchronous motors up to 0.75kW at 230V with independently adjustable frequency ramps for soft-start and soft-stop — reducing mechanical stress on door panels, guides, and drive chains.

What safety systems does it support?

The controller features an integrated safety edge interface compatible with resistive 8k2 sensing edges and dynamic optical safety systems. Additional safety inputs accommodate photo eye beam sensors, induction loops via plug-in detector module, and radar motion sensors. A 24V safety extra-low voltage output per EN 60335-1 powers external safety devices, while TÜV type-examination certification confirms compliance with EN 12453 and EN 12978 door safety standards.

How is it configured and commissioned?

An onboard segment display with push-buttons enables direct parameter adjustment without additional tools. For advanced setup, the self-learning auto-configuration routine detects connected motor characteristics and applies factory presets for standard door types. A PC toolbox is available for detailed diagnostics and configuration backup via the service interface.

Can it be expanded with accessories?

A plug-in radio receiver slot accepts a 2-channel module for remote control integration. The 14 digital inputs and 2 programmable relay outputs handle common accessories including signal lights, traffic light control, induction loops, and external warning devices. Colored plug-in terminals simplify wiring and reduce installation time.
