Product Attributes
- Voltage Spike and Transient Protection: The board's primary function is to provide protection for the system's control power circuits against voltage spikes and transients. These electrical disturbances can occur due to various factors such as lightning strikes, power surges, or switching operations within the system. By incorporating a voltage protection circuit, the board actively diverts excess voltage away from sensitive control components. This attribute significantly reduces the risk of damage or system failure caused by such electrical disturbances, ensuring the overall stability and longevity of the system.
- Damage Prevention and System Reliability: By effectively diverting excess voltage away from sensitive control components, the board plays a vital role in preventing damage and maintaining the reliability of the system. It acts as a safeguard, ensuring that critical control components are protected from potentially harmful voltage spikes or transients. This attribute is crucial in applications where system downtime or component failures can have severe consequences, such as industrial processes, power generation, or critical infrastructure.
- Flash Memory for System Configuration and Setup Data: The board incorporates a flash memory chip that serves as a storage medium for system configuration and setup data. This flash memory allows for the retention of critical information that defines the system's operation and behavior. The stored data includes parameters such as control settings, communication protocols, or specific operating modes. The ability to store this information in non-volatile memory ensures that the system can retain its configuration even during power outages or system restarts.
- Reprogrammable Data for Flexibility and Upgrades: The flash memory chip on the board provides the flexibility to reprogram system configuration and setup data as needed. This attribute allows for easy upgrades or modifications to the system without requiring hardware changes. The ability to reprogram the data stored in the flash memory simplifies the implementation of changes, adjustments, or enhancements to the system's functionality, ensuring adaptability to evolving requirements or technological advancements.
- Enhanced System Maintenance and Troubleshooting: The inclusion of flash memory with stored configuration and setup data offers advantages in system maintenance and troubleshooting. In the event of a system failure or reconfiguration, the stored data can be used to restore the system to its previous working state quickly. It also facilitates efficient troubleshooting processes by providing a reference point for comparing system behavior or identifying potential issues related to the configuration or setup.
I/O Isolation and Distribution
- The 48 V ac, 27 kHz control power supply of the drive is fed into the module. An onboard high voltage transformer (T8) protects the input and output by providing 8000 V rms dielectric isolation.
- The secondary of the transformer feeds the output circuits, which are fuse-protected and shielded to chassis ground. Surge protectors are also installed across the terminals of the CPFP's seven output power connectors.
Distributed Control System
- To communicate with the plant's distributed control system, external communication links are available (DCS). This provides the DCS operator with real-time Mark VIe data as well as the ability to send discrete and analog commands to the Mark VIe control. There are three ways to connect the Mark VIe control to the plant DCS.
- Serial Modbus Slave connection to the DCS from the HMI server's RS-232C port or an optional dedicated gateway controller.
- A high-speed Ethernet link at 100 Mbaud using the Modbus Slave over TCP/IP protocol.
- A high-speed Ethernet link at 100 Mbaud using the TCP/IP protocol and an application layer known as GEDS Standard Messages (GSM)
- GSM allows for the transmission of turbine control commands, Mark VIe data and alarms, the alarm silence function, logical events, and contact input sequence of events records with a resolution of 1 ms. Modbus is widely used to connect to DCS, but Ethernet GSM offers greater system integration.
CPFP Isolation lost trip fault
- The CPFP isolation lost trip fault is a hardware-generated issue that warrants attention due to potential compromised isolation within the CPFP power supply isolation card. This card plays a critical role in providing control power to various circuit cards situated in the high voltage compartment. Its design incorporates a dual voltage barrier system, essential for isolating phases from each other and from the control system.
- When the CPFP isolation lost fault is detected, it signifies a breach in one of these crucial voltage barriers. Such a situation is inherently hazardous because if the second barrier were to fail, it could result in the transmission of dangerous voltages into the control cabinet or even provoke a phase-phase short circuit on the CPFP card itself.
- The fault triggers when the status light, transmitted via fiber from the CPFP, ceases to operate. To troubleshoot this issue, the fiber connection from CPFP (PWR OK) to FOSA (SPARE-R) should be carefully examined. To diagnose the problem:
- Inspect Fiber Connection: Ensure that the fiber is correctly installed between CPFP and FOSA. Disconnect the fiber from FOSA and observe for the presence of the status light traveling up the fiber. If there is no light observed, the issue likely lies within the CPFP.
- Check for Light Transmission: If light is visible upon disconnecting the fiber, the problem may be attributed to FOSA or BICM, warranting further investigation in those areas to identify and rectify the fault.
