Dynatect’s Gortite® VF Automated Machine Safety Door can increase productivity while making your processes safer. It’s intended to safely isolate hazardous operations from other industrial processes, material, equipment, and people, while still allowing access to it. The door is installed in conjunction with existing machine guard panels on each side of the door to enhance the separation of environments further.
This high-speed industrial roll-up door is designed to minimize cycle time and maximize production in industrial environments. It satisfies the need of both an automated roll-up door as well as a high-speed industrial door, but with an application emphasis on it being used as secure barrier in automated processes. The door is equipped with a traveling photoeye sensor, that can bring the door to a full stop in a matter of seconds.
Easy Installation— Modular design includes (2) baseplates with leveling screws, (2) legs, (1) header with pre-rolled curtain assembly and gearbox attached, and (1) motor. Unit requires no cutting/drilling/tapping or welding for assembly. Free-standing design not dependent on machine or walls for support. (Anchoring/securing to floor is
Simplicity —All sensor cables terminated on door frame to a passive block with industry standard quick disconnects. Mounted on the motor-side leg column for accessibility and convenience.
Accessibility —Removable aluminum leg covers provide access for options, installation, commissioning, travel adjustment, and preventive maintenance.
Adaptability —Integrated T-slots on legs and header allow for structure and accessory mounting. Legs feature T-slots on side and back. Custom bracketry and wall-mount adaptation available.
Appearance — Attractive appearance enhances your modern facility. All aluminum and steel external surfaces are powder coated (base plate, columns, covers, and top roll header.)
Reliability — Door mechanism moves freely on roller-based guidance system for smooth, low-wear operation. Proximity sensors eliminate the need for mechanical rotary cam switches.
44” per second standard speed
Motor shaft is integrated to the honeycombed roller tube, minimizing motor oscillation
Leg assembly of extruded aluminum profiles and structural 2” square steel tube
Tested for more than 1 million cycles
1 year warranty
Door retained in columns to minimize risk of people falling through closed door (conforms with OSHA guardrail requirements)
Installation at a Manufacturer of Plastic Cases in Cannon Falls, Minnesota. The Gortite® VF Door was chosen for this application to improve safety and housekeeping. The door isolates the CNC machine router, preventing occasional flying debris from exiting the work area.

Safety Sensor Options
These safety sensor options are available with any control system option.
Sensor for detecting interference and supporting door-auto reverse function:
LiDAR Scanner (Non-Safety Rated or Safety Rated)
Fixed Photo Eye(s) for sensing interference while door traveling closed
Fixed 40” Light Curtain
Door Hold-Down Switch:
Latches door in closed-position, controlled by signal from machine
Door Closed Safety Interlock Switch and Safety Relay:
Helps meet PLe/Cat-4 safety requirements when combined with appropriate logic and conformance to risk assessment
Optional safety relay shipped loose or integrated into operator control unit
Safety circuit wiring required during installation
Note: The installer must ensure that the door, its controls, and any safety devices conform to applicable safety standards

Control System Options
Motor & 2 Travel-End Sensors only – (2) 24VDC Proximity limit switches. Motor with industry standard quick disconnect interface (4 conductor). No control box. Contactors, phase-relay, drive, logic, AC-power and DC-power by others. NOTE: Please advise Dynatect if a VFD will be used.
Integrator Control Box Option
Upgrade from “Standard Offering” that includes NEMA 4X (IP66)
control box with contactors, motor starter, and phase-relay. Pre-wired to accept “up” signal, “down” signal, and Standard Travel-End Sensors. Box mounting, field wiring, logic, AC-power and DC-power by others. All pushbuttons by others. Any “Sensor Options” are field wired to customer controls and logic by others. In-box safety relay mounting option.
Variable Speed Controller Option
Upgrade from “Integrator Control Box” with added pushbuttons
(Up, Down, E-stop), external disconnect switch, variable speed drive, 24VDC power and logic for all sensor options. Includes termination to accommodate options of: “LiDAR”, “Fixed Photo Eye”, “Fixed Light Curtain”, and safety interlock. In-box safety relay mounting option.
Motor Mounting Options
Right Angle Motor Mount (up, down, front, back)
In-Line Motor Mount (facing front, facing back, above top roll header) – adds $1700 to total price
Need to see through to the other side? One or more clear windows can be optionally added to the Gortite VF Door to allow for safe supervision of the isolated processes. Standard window size is 18 by 18 inches. For welding applications, red or bronze OSHA compliant UV windows are available.
Use of a physical barrier with safety sensors can save up to 30 square feet of manufacturing space. Using the ANSI minimum safety distance formula, the door limits the depth penetration factor and average approach speed, allowing closer location of the safeguarding device:
Ds = Safety Distance K = 63 in/sec (OSHA hand speed) Ts = Stop Time (in milliseconds) Tc = Response time of machine control (in milliseconds) Tr = Response time of presence sensing device (in milliseconds) Tbm = Additional time (in ms) to permit normal wear of brakes
before safety distance is violated Dpf = Distance (in inches), penetration depth factor
