MTL MTL831C模拟发射机的使用方法

当您自己铺设光纤线或电缆时，请遵循以下说明。1.产品附带使用说明书。接线负责人应首先彻底阅读手册，然后按照说明铺设电线或电缆。2.交付时，确保通过发送光束来测试产品的性能。通过从电线或电缆的一端发送阳光或手电筒光束并确认其到达另一端，可以轻松测试光纤的性能。安装前测试产品性能在铺设电缆之前，客户应检查电缆（交付后立即）是否有任何缺陷。原则上，所提供的保修不包括安装后发现的功能缺陷（如电缆中断）光纤电缆KM61、KM62、KM65、KM67和KM69为定制产品。因此，更换有缺陷的电缆可能需要KM65电缆一周，KM61、KM62和KM67电缆一个月，KM69电缆两个月。

系统设计注意事项

本节包含设计包含FA-M3.A3.3.1电源线布线和紧急停止电路的系统时应考虑的事项。电源线大致可分为三组：一组用于动力设备，一组用于除FA-M3以外的控制设备，另一组用于FA-M3本身。FA-M3的电源线进一步分为一条用于电源模块，另一条用于I/O单元。所有这些电源线必须配备单独的断路器或开关，并单独接线。将FA-M3电源模块上的FAIL OUTPUT端子与外部继电器电路结合使用，以配置紧急停止电路。采用这一策略对于防止整个系统的错误操作或FA-M3中任何可能的故障或失灵至关重要。如果系统存在可能导致人员伤亡的风险，请务必采取适当的安全措施，例如在紧急情况下关闭动力电路的电源，如图A3.9所示。

When you lay the fiber-optic cord or cable yourself, follow the instructions given below. 1. The product comes with an instruction manual. The person in charge of wiring should first read the manual thoroughly, and then lay the cord or cable as instructed. 2. Upon delivery, be sure to test the performance of the product by sending light beams through it. The performance of optical fiber can be easily tested by sending sunlight or flashlight beams from one end of the cord or cable and confirming their arrival at the other end. Test the performance of the product before installation.- Before laying cables, customers should check the cables (immediately after delivery) for any defect. In principle, the provided warranty does not cover functional defects (e.g., cable discontinuity) discovered after installation. - Fiber-optic cables KM61, KM62, KM65, KM67, and KM69 are made-to-order products. Hence, replacement of a defective cable may require a week for KM65 cables, a month for KM61, KM62, and KM67 cables, and two months for KM69 cables.

System Design Considerations

 This section contains the considerations you should take into account when designing a system that incorporates the FA-M3. A3.3.1 Power Line Wiring and Emergency-stop Circuit The power lines can roughly be divided into three groups: one for motive-power equipment, one for control equipment except for the FA-M3 and one for the FA-M3 itself. The power line for the FA-M3 is further divided into one for the power supply module and one for I/O units. All these power lines must be equipped with separate circuit breakers or switches and wired separately. Use the FAIL OUTPUT terminal on the power supply module of the FA-M3 in combination with your external relay circuit to configure an emergency-stop circuit. The adoption of this strategy is essential to prevent erroneous operation of the entire system or any possible failure or malfunction in the FA-M3.If there is a risk that the system could cause injury or death of personnel, be sure to take appropriate security measures, such as power shutdown to the motive-power circuit in the case of an emergency, as shown in Figure A3.9.
