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.
