Page 14: Laser Classification And Warnings
Defender Press Brake Guarding System Operation Manual LS-CS-M-069 These sensors are divided into three zones that represent the front, middle and rear of the laser plane (the FR, MI, RE signals). If an obstruction blocks the laser light to any of the sensors, the receiver will turn off the appropriate signal, and the PGS-2 controller will immediately disable downward movement of the press beam. -
Page 15: Mute Point
The laser to punch distance is displayed in mm, and you must ensure that the laser is set to this distance below the punch tip. Refer to Lazer Safe Alignment Reference Guide (LS- CS-M-017) for a step by step description of how to fully align the laser. -

The operator must release and press the pedal again. The system will force the tools to close in safe speed only with the optical protection muted and display the message LASERS INACTIVE until the bend is completed. -
Page 18: Back Gauge Mode
Defender Press Brake Guarding System Operation Manual LS-CS-M-069 Back Gauge Mode Back Gauge mode is used in cases where the back gauge of the press brake is moving forward far enough to obstruct the rear sensor. When Back Gauge mode is enabled, the rear sensor is muted 16mm above the normal mute point, allowing the back gauge to enter the work space without causing an obstruction. -
Page 19: Mute Mode - Restricted (Optional)
Defender Press Brake Guarding System Operation Manual LS-CS-M-069 Press Brake Guarding System ensures that the machine does not exceed safe speed in this mode, particular caution must still be exercised. 3.10 Mute Mode - Restricted (Optional) The Defender system may be installed on machines that do not support dual speed operation. - Page 20 Defender Press Brake Guarding System Operation Manual LS-CS-M-069 The system also monitors the machine process for failures of hydraulic valves, failures of electrical components, and failures in the machine controller software in relation to the actions of the parts of the machine that pose risk to the operator.

Page 21: Transmitter And Receiver Adjustment
Initial Alignment When the system is first installed, a complete alignment of the laser transmitter and receiver is required. Refer to Lazer Safe Alignment Reference Guide (LS-CS-M-017) for detailed step by step instructions on how to perform a full alignment. - Page 22 Figure 4-3: Tool Locator Tabs To assist in setting the laser to punch distance correctly, Lazer Safe provides magnetic alignment cards, which are supplied with adhesive backed tool locator tabs. The tool locator tabs can be stuck onto the alignment card at the laser to punch distance. The operator can then attach the magnetic alignment card to the punch, locating the tool tip in the centre groove of the locator tab.
- Page 23 Defender Press Brake Guarding System Operation Manual LS-CS-M-069 If the new tool has changed the laser to punch distance, then the laser will not be aligned to the slots in the alignment card. The example in Figure 4-5 shows a laser that needs to be moved down to return to alignment.
