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 system arrives with top roll header fully assembled. Unit requires no cutting/drilling/taping or welding for assembly. Wall-mount adaptation possible with optional steel plates.
Freestanding — Design not dependent on machine or wall for support. Provides consistent design and function across multiple lines & work areas.
Simplicity — Modular system arrives with top roll header fully assembled. Unit requires no cutting/drilling/taping or welding for assembly. Wall-mount adaptation possible with optional steel plates.
Accessibility — Removable aluminum side column covers provide access for installation, travel adjustment, preventative maintenance, and adding accessories such as interlocks.
Adaptability — Side columns and top roll header feature T-slots on multiple surfaces for mounting.
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 on a maintenance-free ball bearing-based guidance system for smooth, low-wear operation.

Overview of Gortite® VF Automated Machine Safety Door’s Key Features
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.
VF Door Motor Phasing & Testing
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.
Safety Sensor Options
These safety sensor options are available with any control system option.
Sensor for detecting interference and supporting door-auto reverse function:
Traveling Photoeye (bottom edge monitoring)
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
(1) Door-Mounted Motor with quick-disconnect interface
(1) NEMA 4X (IP66) control box with motor contactors
Control box logic to accept inputs from (2) Door Mounted “Travel End” Sensors, 3rd-party “up” signal, and 3rd-party “down” signal
Box mounting and all field wiring by others
(1) 24VDC Power Supply and (3) Pushbuttons (Up, Down, E-stop)
Terminations and logic to accommodate options of Traveling Photo Eye, Fixed Photo Eye, Fixed Light Curtain, and Safety Interlock
Motor Mounting Options
In-Line Motor Mount (facing front, facing back, above top roll header)
Right Angle Motor Mount (up, down, front, back)
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
