If any out of three (Normal Combustion / Remote/ 52G GCB Closed) signal is disable (AGC feedback) GLC Disable signal will enable & following things will happen in Auto:AGC Mode will be Non select, Manual Mode will be Non select, AGC GT high load limit SP will follow GT active MW, AGC GT load rate will be zero

If AGC in auto operation & due to any circumstances we put any/both GT from Remote to Auto (GT HMI) selection the above mentioned things will happen following GLC Disable signal enable, Now If we put GT in Remote the sequence is :

1) Put GT Mode in Remote selection: GLC Disable will disable, confirm it from feedback. 2) Select Auto/Manual AGC Operation (Confirm the AGC feedback)3) Confirm Load external selection enable feedback4) Put the SP of AGC GT high load limit ( REMOTE selection> Set AGC GT high load limit (AGC Auto/manual Operation.
