统检测操作员的存在，以防止操作员在围栏内时重置周界防护系统并重新启动机器。图13合适的周界防护系统应为固定式防护装置，该防护装置配有带条件防护装置解锁的联锁开关的检修门（见ISO14119）。诸如安全光幕的跳闸装置也可适用于某些应用。需要注意的是，光幕的位置必须根据EN 999进行计算。在这些应用中使用Allen-Bradley Guardmaster系统时，操作员可接近的整个封闭地板区域应覆盖传感器垫。固定防护联锁门（带锁）危险传感器垫罗克韦尔自动化出版物95302194/EO:0240发行号：8 17 440F MatGuard™ 垫子管理员用户手册第5节-安装设计5.5固定防护装置固定防护装置的设计应确保除了通过Allen-Bradley防护装置主垫子外，不可能进入危险区域。防护结构和定位应符合EN 953、ISO13852（EN294）和ISO13853（EN 811）。5.6良好的安装设计和防止旁路的措施如果不站在Allen-Bradley护栏主垫上，就不可能到达危险区域。必须防止从不需要站在Allen-Bradley警卫席上的位置进入危险区。这通常需要额外的角板和电缆槽的小心定位。这方面的良好实践如图14所示。图14 1。固定防护装置防止进入危险区域，使得防护装置和传感器之间无法进入。2.倾斜盖板防止操作员站在机器底板上避开感应区域。3.传感器边缘的跳闸危险通过入口处的斜坡减少。斜坡还可以保护连接电缆。AllenBradley Guardmaster周界修剪是一个斜坡段。4.电缆槽安装在固定防护装置的外部。这可防止其被误用为进入危险区域。5.复位按钮位于保护良好的位置，可完全看到机器。6.垫安装正确。5.7电气接口Allen-Bradley Guardmaster系统提供的保护取决于Allen-BradleyGuardmaster系统与机器之间的正确接口。Allen-Bradley Guardmaster控制单元的安全输出触点设置为独立的无电压N/O触点对。
the Allen-Bradley Guardmaster system detects the presence of an operator to prevent the perimeter guarding system being reset and the machine re-started while the operator is inside the enclosure. Figure 13 A suitable perimeter guarding system would be a fixed guard with an access door fitted with an interlock switch with conditional guard unlocking (see ISO14119). A trip device such as a safety light curtain may also be suitable for some applications. It is important to note that the positioning of the light curtain must be calculated according to EN 999. When using the Allen-Bradley Guardmaster system for these applications the entire enclosed floor area accessible to the operator should be covered by sensor mats. Fixed Guarding Interlocked Door (with locking) Hazard Sensor Mats Rockwell Automation Publication 95302194/EO:0240 Issue No: 8 17 440F MatGuard™ Mat Manager User Manual Section 5 - Installation Design 5.5 Fixed Guards The fixed guards should be designed so that access is not possible to the hazard zone other than via Allen-Bradley Guardmaster mats. Guard construction and positioning should be in accordance with EN 953, ISO13852 (EN294) and ISO13853 (EN 811). 5.6 Good Installation Design and Measures Against Bypass It must not be possible to reach the hazard without standing on the Allen-Bradley Guardmaster mats. Access to the hazard zone from positions which do not involve standing on the Allen-Bradley Guardmaster mats must be prevented. This will typically require additional angle plates and careful positioning of cable troughs. Good practice in this respect is illustrated in Figure 14. Figure 14 1. Fixed guards prevent access to the hazard zone in such a way that there is no access between the guard and sensors. 2. A sloping cover plate prevents the operator eluding the sensing area by standing on the machine base plate. 3. The tripping hazard at the sensor edge is reduced by a ramp at the point of access. The ramp may also protect connecting cables. The AllenBradley Guardmaster perimeter trim is a ramp section. 4. Cable troughs are installed outside of the fixed guard. This prevents its misuse as access to the hazard zone. 5. A reset button is located in a well protected location giving full visibility of the machine. 6. Mats are properly installed. 5.7 Electrical Interfacing The protection provided by the Allen-Bradley Guardmaster system depends on the correct interfacing between the Allen-Bradley Guardmaster system and the machine. The safety output contacts from the Allen-Bradley Guardmaster control unit are arranged as independent voltage free N/O contact pairs.
