General Electric (GE) created the DS3800NPCR to be a component in the Speedtronic Mark IV (MKIV) series. This is a series of components used to control turbines. This includes both steam and gas turbines. Mark IV is the third series in the Mark system. Mark IV was preceded by the Mark I and Mark II systems. These systems were based on the automation of turbine control, protection, and sequencing. These techniques have been in development since the end of the 1940s. The first Mark system, Mark I, was first introduced in the late 1960s.
The Mark IV control system features what was state of the art technology. The Mark IV fulfills all of the requirements of both gas and steam turbines. This includes controlling fuels and temperatures as well as steam and water injection. Auxiliary functions, as well as shutdown and cooldown are regulated by the Mark IV. The Mark IV features built-in diagnostics including power up, background, and manually initiated diagnostics. These diagnostics are very useful for troubleshooting and repairing turbines. The Mark IV features a printer which can copy any display which is shown on the CRT. The printer also logs alarms with a time stamp to help operators keep a record of issues. These logs can capture the cause of a problem and are very useful for troubleshooting. The Mark IV is in charge of fuel, air and emissions control, fuel sequencing, and protection against unsafe conditions.
AX Controls ships all products, including the DS3800NPCR, in static resistant packaging this gets rid of static energy to protect the operator when it is opened.
