GE DS3800HARA1B1C Gas turbine serial card

If the [SERVO ON READY] lamp does not light in previous operation (2), 

check the following: 

• The emergency stop button on the playback panel is pressed.

 • The emergency stop button on the programming pendant is pressed. 

• The emergency stop signal is input from external. If the servo is not turned on in a previous operation (4), check the following: 

• The overrun LS is operating. 

• If a major alarm is occurring

Battery Inspections 

The XRC has a battery that backs up the important program files for user data in the CMOS memory. A battery alarm indicates when a battery has expired and must be replaced. The programming pendant display and the message "Memory battery weak" appears at the bottom of the display. The way to replace the battery is described in “9.1.1 Replacing Parts of the CPU Rack”.Confirm if the lead cable for the power supply is wired as shown in the following. If the wiring is wrong or broken, repair it.Turn on the control power supply and check the open phase voltage of “U,V,W” of the circuit breaker (QF1) with an electric tester. If abnormal, replace the circuit breaker

Replacing XRC Parts

• To prevent anyone inadvertently turning ON the power supply during maintenance, put up a warning sign such as "DO NOT TURN ON THE POWER" at the primary power supply (knife switch, wiring circuit breaker, etc.) and at the YASNAC XRC and related controllers and use accepted lockout/tagout procedures. Failure to observe this caution may result in electric shock or injury. • Do not touch the regeneration resistors. They are very hot. Failure to observe this caution may result in burn injuries. • After maintenance is completed, carefully check that no tools are left inside the YASNAC XRC and that the doors are securely closed.
