Functional Description

DS200GHDQF1CBD is a Software EPROM Set developed by GE. It is a part of Mark V control system. EPROM, or Erasable Programmable Read-Only Memory, is a type of non-volatile memory used extensively in computing and electronics for storing data that must be preserved when the power is turned off. One of the defining features of EPROMs is their ability to be erased and reprogrammed, which distinguishes them from other types of ROM (Read-Only Memory) that are either non-erasable or require complex processes for data modification. The data stored in an EPROM remains intact even when the device is powered down, making it suitable for applications where data longevity is crucial.

Master Trip Circuit

• The Mark V control system safeguards the turbine through a robust Master Trip Circuit. This circuit leverages multiple cores within the control panel to achieve reliable trip decision-making. It functions in two stages: inputs received by the Mark V and outputs generated by the system.
• The Master Trip Circuit receives hardwired or remote trip signals (contact opens to trip) through dedicated inputs. These inputs connect to the coils of relays designated as 4's. This crucial stage employs redundancy.
• One set connected in series with the external trip contact inputs and the positive DC bus.
  Another set connected in series with the negative DC bus.
  This configuration ensures that a single failed relay coil in the 4's won't cause an unintended turbine trip. The remaining healthy hardware contact within the relay will overrule the faulty coil, preventing a spurious trip.
• For a turbine trip to occur, both relays connected to the same DC bus (positive or negative) must be de-energized. This two-step confirmation process minimizes the risk of accidental trips due to isolated component failures.
• In essence, the Mark V Master Trip Circuit prioritizes reliable trip decisions through redundancy and a deliberate de-energization requirement. This multi-layered approach enhances the safety and operational stability of the turbine.

Frequently Asked Questions

What is DS200GHDQF1CBD?
It is a Software EPROM Set developed by GE under the Mark V series.

How do you erase data from an EPROM?
Data is erased by exposing the chip to UV light through a quartz window. This process typically takes about 20 minutes and removes the charges from the floating gates, effectively resetting the memory cells.

How is data programmed into an EPROM?
Data is programmed by applying a higher than normal voltage to the transistors to inject electrons into the floating gate. This process requires a special device known as an EPROM programmer.

What are the advantages of using EPROMs?
EPROMs offer the advantages of being reusable and having excellent data retention capabilities. They can be erased and reprogrammed multiple times and can retain data for many years without power.
