Can someone please explain the below protection of GE 9E MKVIe
Below I have got these from GT HMI Trip Diagram. Why there are so many protection signals related to speed. If someone can explain the below one by one.<pre>
L12HF Loss of control speed signal
L12HFD_P HP over speed fault-protective input trouble
L12HFD_C HP over speed fault-Control input trouble
L12H_P PPRO HP over speed trip
L22h_ACC PPRO Loss of protective speed signal
L12_HPW_TREA Over speed Hardware TREA
L12H_P_HW Over speed Hardware trip signal
L12H_HP_TREA Over speed TREA trip</pre>
