Figure 3-2: Sentinel Plus Press Brake Guarding System Components Optical Protection Overview The Sentinel Plus Press Brake Guarding System comes as standard with the LZS-005-R Block Laser transmitter and receiver pair. The transmitter and receiver are mounted on the upper beam of the press brake, allowing the operator to remain close to the work-piece as the tools close at high speed. -
Page 15: Laser Classification And Warnings
3.3.2 LZS-005-R Block Laser The Sentinel Plus system employs a LZS-005-R Block Laser transmitter and receiver. The transmitter projects a square beam of laser light approximately 80mm wide by 50mm high that surrounds the upper tool. This creates a silhouette (or shadow) of the upper tool on the... -

Figure 3-3). In the illustrations describing the operation of the Sentinel Plus the lasers are shown in segments to highlight the sensor zones, however the guarding region is a continuous band around the tool tip. The system can mute these individual zones when forming various shape work pieces (e.g. -

Open Tools Enable button. The enable outputs will remain on only while the tools are opening, and will turn off again at the end of travel. Tray/Box Modes The Sentinel Plus supports two types of Tray/Box mode. In Normal mode a workpiece with large side flanges (as shown in Figure 3-5) would trigger an obstruction and force the press into slow speed for a long distance. -

However, the Sentinel Plus system maintains all of its other safety functions. For example, it continues to monitor that the closing of the tools occurs at safe speed and stops the machine if that speed is exceeded. -
Page 20: Special Guarding Modes
3.9.1 Special Tools Mode The tool tip finding process in the Sentinel Plus is designed around V tools that are used in most press brake operations. Once the tool tip is found the optical protection is set to guard the danger zone around the tool tip. -
Page 21: Thermal Compensation Mode
(as recommended by European Standard EN12622). If the Sentinel Plus is in Special Tools mode, and a large tool has been detected that requires a 20mm mute/slow speed point, a Stop at Mute will also be performed on every stroke. -
Page 22: Tool Set-Up Mode (Optional)
Tool Set-up mode. Tool Set-up Mode is only required for some models of press brakes. In Tool Set-up mode the Sentinel Plus will attempt to restrict the tool closing speed to crawl speed (the crawl speed output Y02 is active). However, some models of press brake ignore the crawl signal in Tool Set-up mode, and permit higher closing speeds. -
Page 23: Light Curtain Mode (Optional)
3.11 Light Curtain Mode (optional) The Sentinel Plus system also supports dual guarding, where a third party light curtain can be connected to the PGS-3. This gives the machine operator an option to select either the laser guarding function or light curtain function. When in Light Curtain Mode the Sentinel Plus continues to control the mute, speed and stop time monitoring functions. -

Sentinel Plus Press Brake Guarding System Operation Manual LS-CS-M-073 A tool alignment is performed, and the receiver will prompt the operator with directions that will move the receiver into the optimum position. After the tool change, the mute point is then set and confirmed by the operator on the first stroke. -
Page 25: Lzs-005-R Operation
LZS-005-R Operation This section describes the operation of the LZS-005-R block laser transmitter and receiver, and in particular the automatic tool alignment feature of the Sentinel Plus system. Alignment Procedure The LZS-005-R receiver features automatic tool alignment, where the image of the tool silhouette is analysed by the receiver, the tip of the punch is located and the protection zone is accurately aligned with the tool tip position. - Page 26 Sentinel Plus Press Brake Guarding System Operation Manual LS-CS-M-073 Move the receiver UP Move the receiver DOWN Move the receiver LEFT Move the receiver RIGHT (front of machine) (rear of machine) Figure 4-4: Receiver Alignment Correction In some cases (extreme environmental conditions, unusual tool shapes, poor alignment etc.) the automatic tool alignment may not be able to find the tool tip.
