Functional Description

5417-027 is a NetCon LoDen Analog Cable developed by Woodward. The cabinet serves as a shield termination point for cables entering the enclosure. Shielded I/O shields must be connected to the FTM shield pins and either AC or DC terminated directly to the cabinet (earth ground) at the cabinet's entry. Cable shield termination hardware must be installed at cable entry points and must be electrically connected to the structural frame to allow direct grounding or AC (capacitive) grounding of cable shields.

Product Attributes

• Customer installations necessitate the use of double-shielded Cat 5 Ethernet cables (SSTP). Using shielded cable will help to ensure the reliability of serial communications. When connecting to the CPU module's serial interface, a shielded cable is necessary.
• Using shielded cable will help to ensure the reliability of serial communications. Each expansion rack can be situated up to 30 meters away from the main CPU chassis using copper Ethernet cables and switches. Each extension rack can be situated up to 2 kilometers away from the main CPU chassis using fiber optic cables and switches.

Troubleshooting

• Check cable connections if the Main XCVR module is not working or is not working properly.
• If the module is still not working properly after checking the cable connections, replace the cables that connect to it.
• Replace the module if it is still not working properly after changing the cords.

System Features

• Control systems with multiple 2 CH Actuator modules (part numbers 5501-428, -429, -430, -431, -432) have the potential to generate a 'beat' frequency of around 3000 Hz. This signal has been known to cause fluctuations in low amplitude signals such as RTDs and thermocouples, as well as to generate noise within the chassis.
• It may also cause increased noise in other analog signals. The source of the problem is that each actuator module generates an excitation signal (either LVDT or RVDT) that is independent and asynchronous to the other actuator modules producing the same output.
• Because these signals are likely to be slightly offset in frequency and amplitude, a corresponding beat frequency on the chassis backplane and on the analog common line may develop.
• When using copper RS485 cable, avoid using any intervening devices such as relays or terminal blocks to ensure reliable communications. The cable should be connected directly from one RS-485 device to the next.
