MTL MTL831C模擬發(fā)射機的使用方法
當您自己鋪設光纖線或電纜時，請遵循以下說明。1.產品附帶使用說明書。接線負責人應首先徹底閱讀手冊，然后按照說明鋪設電線或電纜。2.交付時，確保通過發(fā)送光束來測試產品的性能。通過從電線或電纜的一端發(fā)送陽光或手電筒光束并確認其到達另一端，可以輕松測試光纖的性能。安裝前測試產品性能在鋪設電纜之前，客戶應檢查電纜（交付后立即）是否有任何缺陷。原則上，所提供的保修不包括安裝后發(fā)現(xiàn)的功能缺陷（如電纜中斷）光纖電纜KM61、KM62、KM65、KM67和KM69為定制產品。因此，更換有缺陷的電纜可能需要KM65電纜一周，KM61、KM62和KM67電纜一個月，KM69電纜兩個月。
系統(tǒng)設計注意事項
本節(jié)包含設計包含F(xiàn)A-M3.A3.3.1電源線布線和緊急停止電路的系統(tǒng)時應考慮的事項。電源線大致可分為三組：一組用于動力設備，一組用于除FA-M3以外的控制設備，另一組用于FA-M3本身。FA-M3的電源線進一步分為一條用于電源模塊，另一條用于I/O單元。所有這些電源線必須配備單獨的斷路器或開關，并單獨接線。將FA-M3電源模塊上的FAIL OUTPUT端子與外部繼電器電路結合使用，以配置緊急停止電路。采用這一策略對于防止整個系統(tǒng)的錯誤操作或FA-M3中任何可能的故障或失靈至關重要。如果系統(tǒng)存在可能導致人員傷亡的風險，請務必采取適當?shù)陌踩胧?，例如在緊急情況下關閉動力電路的電源，如圖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.
