Sentinel Plus Press Brake Guarding System Operation Manual LS-CS-M-073Page 47Original Language Version: 1.04 Released: 19/07/20177 Light Curtain Mode (Optional)The Sentinel Plus Press Brake Guarding System supports dual guarding, where both theLZS-005-R laser guarding and a third party light curtain can be installed on the samemachine. The operator can select which guarding system best suits the parts that are beingformed. Changing the type of optical protection, and setting/resetting the mute point while inLight Curtain mode is restricted to Supervisor level access.Note:To use light curtains the Sentinel Plus system must be configured with operatingparameters for the OEM products that have been installed. If this is not done thelight curtains will not operate correctly. This requires access to the System menu,and must be done by a trained and qualified Sentinel Plus installer.The active optical guarding system can be selected through the Supervisor Menu in theUser interface Panel. When light curtains are selected, the Sentinel Plus system willdeactivate the laser guarding and activate the light curtain guards. When the light curtain isactive the system will automatically monitor the machine motion, speed and stopping time,as well as control the light curtain muting.When the light curtain is first activated the operator will be required to set a new mute point.This is a manual process where the operator closes the tools until the punch contacts thematerial - this is the pinch or zero opening point. The operator then confirms this position bypressing the SET button and the system automatically sets the mute point at 6mm (1/4”)above the zero opening position. During machine operation the light curtain remains activeuntil the mute point is reached; at this point the light curtain is automatically muted.Warning: REFER TO THE LIGHT CURTAIN MANUFACTURER’SDOCUMENTATION BEFORE OPERATING LIGHT CURTAIN MODE.The light curtain is a third party device and is not manufactured or supplied byLazer Safe.
