Frequently Asked Questions about DS200FCGDH1A

What does the DS200FCGDH1A board do?

The DS200FCGDH1A receives SCR firing information from the DSPC board and returns diagnostic and feedback information via the VME backplane. Not only does the DS200FCGDH1A board perform the aforementioned it receives and scales bridge feedback signals and will then send the voltages, current status information, and frequency back to the DSPC board. 

One of the functions within the DS200FCGDH1A board is to receive voltage feedback from the Voltage Feedback Scaling (NATO) board, what do these signals include?

The signals included from the NATO board are five attenuated analog voltage signals which correspond to the plus/minus DC, as well as three AC voltages which are all referenced to ground through a local resistor. 

What is the system heartbeat?

The system heartbeat is a periodic signal that is generated by an electric component to announce the component imbedded within the DS200FCGDH1A is still functional.

What is the compatibility of the DS200FCGDH1A board?

The FCGD board is compatible with the VME (A24/D16) bus specification both electrically and physically. The typical environment surrounding the DS200FCGDH1A board is four FCGD boards and a VME bus host CPU.

Product Description

Model number DS200FCGDH1A is a Gate Distribution and Status Model is an interface board that is a six-pulse-phase-controlled non-reversing bridge model. The primary function of the interface board is to receive silicon-controlled rectifiers (SCR) firing information from the DS200DSPCH1A model, which is the VME processor, that will return diagnostic and feedback information through the VME backplane. This model has six layers as well as SMDs (surface-mounted devices). 

One of the functions of the DS200FCGDH1A is a system heartbeat. The heartbeat is a signal that is sent intermittently, this heartbeat signal is generated by electronic components, the purpose of which is to ensure that the component is still functioning. Please note that when operating this model if the heartbeat exceeds a number greater than eight milliseconds the front IMOK LED and gating will both turnoff, if this occurs then a hard reset will need to occur to exit this condition. 

The LS2100 Series model number, DS200FCGDH1A, has three hardware overcurrent signals which will combine to form an IFB signal. If the IFB signal receives a signal that is greater than or equal to that of twenty-six milliseconds the overcurrent signal that occurs on the FCGD will need to be cleared by a hardware reset.
