The Guardian Defender™
The Safer, Environmentally Friendly, Cost Saving Light Curtain Alternative
Frommelt Safety introduces the Guardian Defender™, the industry's most effective machine guarding device yet. Designed with the latest regulations and most demanding manufacturing process in mind, the Guardian Defender is the ideal safety guarding device in many manufacturing environments. Anywhere that a machine operator interfaces with a machine, robot or process is an ideal application for the Guardian Defender.
What is a safety light curtain?
A safety light curtain is an optically driven, non-contact method of machine guarding and are a form of perimeter access guarding that falls into the category of "presence sensing devices" much like safety mats, photo eyes and safety laser scanners.
Safety light screens use a series of infrared beams to sense the presence of an obstruction, stopping machine movement before the hazard can be accessed. Additionally, they are connected to a safety relay or control, this safety relay communicates to the machine or application that is being guarded. When a beam is interrupted, a signal is sent through the safety relay to the machine and ceases motion.
A safety laser (area) scanner is much like a safety light curtain, a non-contact method of machine guarding also using perimeter access guarding. Safety laser scanners are also considered a presence sensing device. The difference of safety laser scanners from safety light curtains is that they send out a fan shaped beam that can detect movement. Safety laser scanners may be programmed to sense various distances and be set for various resolutions. Safety laser scanners are also connected to a safety relay control.
Automated barrier doors, roll up curtains as an alternative:
Frommelt Safety manufactures a number of automated barrier doors, roll up curtain doors and innovative machine guarding solutions that are ideal alternatives to safety light curtains. By using non-contact, coded signal switches and safety rated relays (controls) Frommelt Safety can deliver the same level of safety (up to Cat. 4 per EN954-1, and/or PLe per 13849-1 when integrated properly) as light curtains, safety light curtains, safety light screens, safety laser scanners and laser scanners with the added benefit of providing a high speed retractable safety guard between the machine operator and the process being guarded.
By guarding points of operation, and limiting access points through both electronic and physical means, Frommelt Safety's complete line of Roll up barrier doors offer the best in automation safeguarding solutions.
The Guardian Defender, Retractable Safety Door Advantages
Safety
- Contains secondary hazards associated with the manufacturing process, ideal as automation safeguarding
- Guards employees from weld flash, sparks, splash, flying debris and other process driven hazards
- Uses non-contact coded signal switches and actuators to monitor and maintain that the doors is in the safe position. Up to Cat. 4 and/or PLe per EN/ISO 13849-1.
- Machine guarding that is VISIBLY SAFER! Fully sealed barrier tabs on curtain edge have 450# tear-out strength
- Multiple brands of switches/actuators and controls integrated with barrier protection enhances machine safety
- Electronic and physical means of controlling access. Provides up to Cat. 4 or PLe with proper control wiring.
Environment
- Interlocked Barrier Doors reduce footprint of manufacturing cell by locating closer to hazard. Greatly reduces the need for a “safety zone”. May/can apply the same safety distance formula
- Reduces footprint of manufacturing cell by locating closer to hazard. Greatly reduces the need for a “safety zone”
- Frommelt Safety’s Automated Curtains are ideal in applications that require additional space for light curtains because it is also a movable physical barrier that can be locked or programmed to delay opening to allow for machine to de-energize.
Productivity
- Increases productivity by locating closer to hazard and provides clear visual cue for operator to be on task
- Allows operator to pivot to load and unload parts due to reduced “safety zone” space requirements.
- Soft Bottom edge enhances safety
- Designed to stand up in the harshest manufacturing applications
- TEFC motors and curtain fabrics designed to withstand application and environmental conditions.
- Optional windows allow for continuous monitoring of the process.
- Gravity down operation - not powered down.
