Setting the Standard for Door Control. Again.

In 1990, Rytec’s Digital Gateway® PLC-based door controller set the industry standard for flexibility and ease of use. Incorporating state-of-the-art motion control technology, the System 3® controller has raised the bar. It combines the flexibility and performance of AC Drive technology with the ease and precision of digital control.

The System 3® displays operational and diagnostic messages in English, Spanish or French. From making adjustments to setting parameters to troubleshooting problems, the System 3 is simply the best door controller ever.

Smoother Operation and Fewer Adjustments

Variable frequency drive makes for soft starts and stops. It also allows for speed adjustments in either direction even after initial installation. And its dynamic braking virtually eliminates the need for brake adjustments and reduces brake wear.

Easy, Flexible Programming

The System 3 features numerous pre-set and custom programming capabilities to accommodate traffic lights, air locks, freezer defrost systems and more, without requiring additional electrical components. Plug-in modules for floor loop and radio control activation make it simple and fast to add these options.

Precision

An absolute rotary encoder provides easy setting and adjustment of door positioning from the panel itself. A two-line, 32-character LCD display makes operational and diagnostic messaging clear and precise in English or Spanish.

Activator Options

The System 3® door controller is designed to operate with many different activators, depending on the application and operating environment.

Floor Induction Loop

Activation loops embedded into the concrete on both sides of the doorway substantially reduce operator error in opening and closing doors. With no moving or exposed parts, floor induction loops are extremely reliable.

Motion Detectors

Motion detectors operate on microwave technology. They detect pedestrian and vehicle motion in a prescribed area. The detector sends a signal to the controller to open the door.

Presence Sensors

Presence sensors detect pedestrians and vehicles in the area of the detector. Motion is not necessary. The sensor signals the controller to open the door.

Radio Controls

A radio control consists of a transmitter and a receiver. The vehicle operator activates the transmitter which sends a signal to the receiver. The receiver then signals the controller to open the door.

Push Button

The push button is generally used with pedestrian traffic and is typically mounted on the wall near the door. Pedestrians push the button as they approach the door, which signals the door to open.

Pull Cords

The pull cords are switches mounted on the ceiling. Pedestrians and vehicle operators pull the cord as they approach the door, signaling the controller to open the door. Vehicle operators generally have to slow down to pull the cord.

Photo Eyes

The photo eye sends a beam across the path leading to the door. If the beam is broken, it sends a signal to the controller to open the door.

Multiple Activators

The System 3® door controller permits many activators to be used in multiple combinations. For example, a door can be opened by forklifts through induction floor loops and by pedestrians through a push button, each with independent closing times to allow for pedestrians passing through the door.

Airlocks

In airlock applications, one controller with various activators permits doors to be interconnected so only one door is open at a time.

Expansion

Optional expansion board provides an additional eight inputs and five outputs.

Optional Activation Modules

Controller is designed to accommodate plug-in floor loop and radio control activation modules, thus eliminating any extra wiring.

Defrost Modules

Defrost system control made available with expansion
board and larger enclosure.
