A自动复位模式当在自动复位模式下使用时，机器的控制系统将需要一个单独的复位功能，以防止机器在离开垫子或临时电源故障或下降后启动。选择电源系统提供四种电源选择，在任何情况下，机器都会提供合适的电源。检查电源参数是否符合规范中给出的垫系统要求。如果使用24V AC或DC电源，则必须根据国际电气安全惯例（IEC 364-4-41）将其与主电源隔离。一个极应接地（直流电源负极接地）。如果必须作出特殊安排，则可随时提供适合系统的24V DC商用装置。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。
UTO RESET MODE When used in the auto reset mode, the machine’s control system will need a separate reset function to prevent machine start up when stepping off the mat or after a temporary power supply failure or dip. SELECTING THE POWER SUPPLY The system offers four possibilities for power supply and in virtually every case a suitable supply will be available from the machine. Check that the power supply parameters conform with the requirements of mat system as given in the specification. Where a 24V AC or DC supply is used it must be isolated from the mains supply in accordance with international electrical safety practice (IEC 364-4-41). One pole should be earthed (negative to be earthed for DC supplies). If special arrangements have to be made, 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.
