Sentinel Plus Press Brake Guarding System Operation Manual LS-CS-M-073Page 12Original Language Version: 1.04 Released: 19/07/20173 System OverviewThe Lazer Safe Sentinel Plus Press Brake Guarding System is a guarding system designedfor hydraulic press brakes that provides a highly effective solution for both operatorprotection and machine productivity.3.1 Key Benefits• Sentinel Plus gives the operator unrestricted access to the tooling area.• The operator can hold the work piece as close as 20mm to the bend line andoperate the machine at high speed.• Complex shapes can be produced with the "Tray / Box" and "Field Muted" modes ofoperation.• The Sentinel Plus system continuously monitors the machine speed and stoppingdistance in real time.• In Normal mode the LZS-005-R block laser detects obstructions as small as 2mm,allowing a mute point of 2mm.• The 2mm mute point is set on the first stroke. The laser guard detects the materialposition, and the operator confirms the mute point.• Failure detection is performed by real-time monitoring of the process under control.• Sentinel Plus also supports a wide range of third party light curtains. The operatorcan easily switch between laser guarding or light curtains.• Supports non ‘V’ tools with Special Tools Mode.• The Sentinel Plus system can be installed either at the time of manufacture or as aretrofit to a press brake already in service.Figure 3-1: Sentinel Plus Press Brake Guarding System Key FeaturesAutomatic Mute Point Set-upThe 2mm mute point set-up is automatically initiated on the firstcycle. The system detects the material surface and the operator isprompted to confirm the mute point via the User Interface Panel. Thesystem automatically monitors the mute position and detectschanges in tool size and material thickness.Sentinel User Interface PanelThe 4.3” colour graphicsdisplay makes the system verysimple to operate. A magneticbacking allows the panel to beeasily moved.Laser Transmitter (TX)As the tools close in high speed theprotective zone is progressively mutedwhile machine deceleration and speed ismonitored. The system provides opticalprotection until the opening is 2mm.Close Proximity ProtectionSentinel Plus gives the operator unrestrictedaccess to the tooling area. The operator canhold the work piece as close as 20mm fromthe bend line, and still operate the machinesafely in high speed.Laser Receiver (RX)The camera receiver featuresautomatic Tool Alignment todetect the tool profile forsimple and fast set-up.Quick Adjust BracketsThe TX and RX can bequickly moved clear duringtool change, are easilyadjusted and highly tolerantto machine vibration.Advanced Monitoring FunctionsSentinel Plus automatically monitorsmachine performance in real time. |
