提供24V直流电以适应系统的商用单元是现成的。辅助输出这是作为状态输出提供的非安全输出。它在使用PLC功能机器控制和硬接线安全电路作为PLC状态输入的系统中特别有用。其他用途包括保护方案中的诊断和/或驱动状态灯或警报。安全功能不得依赖于此输出。电弧抑制建议所有感应负载使用电弧抑制网络或设备。对于安全电路，抑制器应安装在负载上，而不能安装在触点上。抑制器的类型和额定值将由电源和负载特性决定。注意，抑制器可以增加响应时间，特别是直流线圈两端的抑制器二极管，并且在测量响应时间时应安装到位。控制单元安全输出电源至控制单元执行力时间20ms响应时间控制单元安全输入电源至控制装置重置执行力时间20m s响应时间24接触器监控接触器监控通过标记为MC的两个端子提供。它应用于所有双通道双接触器系统。如果其中一个接触器未能隔离电源，则垫控制单元将锁定并防止另一个接触器重新通电，直到故障得到纠正。5.8最终传感器垫布局考虑到这些因素后，现在可以检查并最终确定传感器垫布局。考虑机器响应时间是否与初始计算有所不同。在可能的情况下，应在检测区的外侧边缘设置垫子和电线。这简化了安装和更换（如果需要），并且所有布线都受到周边装饰的保护。5.9布线所有系统布线必须防止机械损坏，并适当密封以适应操作环境。提供防水对接接头用于垫子到垫子的连接，并由边缘镶边保护。如果需要在地板上布线，440F-T3230导线导管可以提供适当的保护。其他电线线路应使用导管或线槽。控制装置的密封完整性必须通过使用尺寸正确且紧固的导管配件或电缆压盖保持在IP65。布线实践必须符合EN 60204-1第14条的要求。注意：为了确保110/230V电源的隔离，输入电源必须单独布线，并通过用于输出接线的单独配件或压盖进入控制单元。从控制单元到垫子的电线可以使用导管埋在地板中，或通过边缘装饰件。此类安装建议使用挠性导管。详见第6节。确定接线方法，并确定控制单元接线垫的输入和输出连接点。5.10最终细节准备安装布局和电路的工作计划和图纸。建议将所有测量和计算记录并保存在机器的技术文件中。25第6节-安装和调试开始安装前，应完整阅读本手册。
commercial units supplying 24V DC to suit the system are readily available. AUXILIARY OUTPUT This is a non-safety output provided as a status output. It is particularly useful in systems using PLC functional machine control in combination with hard wired safety circuits as a status import to the PLC. Other uses include diagnostics in protection schemes and/or driving status lamps or alarms. The safety function must not depend on this output. ARC SUPPRESSION Arc suppression networks or devices are recommended for all inductive loads. For safety circuits, suppressors should be fitted across the load and never across the contacts. The type and ratings of the suppressors will be determined by the supply and load characteristics. Note that suppressors can increase response time, particularly suppressor diodes across DC coils, and should be in place when measuring response times. CONTROL UNIT SAFETY OUTPUTS POWER TO CONTROL UNIT ACTUATING FORCE TIME 20ms Response time CONTROL UNIT SAFETY OUTPUTS POWER TO CONTROL UNIT RESET ACTUATING FORCE TIME 20ms Response time 24 CONTACTOR MONITORING Contactor monitoring is provided via the two terminals marked MC. It should be used in all dual channel two contactor systems. If one of the contactors fails to isolate the power, the mat control unit will lock out and prevent the re-energisation of the other contactor until the fault is rectified. 5.8 FINAL SENSOR MAT LAYOUT Having considered these factors, the sensor mat layout can now be checked and finalised. Consider whether the machine response time has changed from the initial calculations. Whenever possible, mats should be arranged with the wires at the outside edge of the detection zone. This simplifies installation and replacement if required and all wiring is protected by the perimeter trim. 5.9 WIRING All system wiring must be protected from mechanical damage and suitably sealed for the operating environment. Waterproof butt connectors are supplied for mat to mat connections and are protected by the edge trim. Where wire runs are required across the floor, the 440F-T3230 wire guide can provide suitable protection. Conduit or trunking should be used for other wire runs. The sealing integrity of the control unit must be maintained by the use of correctly sized and tightened conduit fittings or cable glands to IP65. Wiring practices must be in accordance with EN 60204-1 Clause 14. NOTE: In order to ensure the isolation of the 110/230V supply, the input power supply must be separately routed and enter the control unit via separate fittings or glands to those used for the output wiring. Wiring from the control unit to the mat may be buried in the floor using conduit, or pass via the edge trim. Flexible conduit is recommended for this type of installation. See section 6 for further details. Determine the wiring method and determine the input and output connection points for the mat to control unit wiring. 5.10 FINAL DETAILS Prepare a work schedule and drawings of the installation layout and the electrical circuit. It is recommended that all measurements and calculations are recorded and retained in the technical file for the machine. 25 Section 6 - INSTALLATION AND COMMISSIONING This manual should be read in full before commencing installation.
