A14B-0076-B10 Fanuc 11 input unit. This unit almost never fails. Green LED indicates that Green ON pushbutton has been pushed. If Red LED is on, the main power supply is probably bad or an output voltage (usually 24V) is shorted. If the main power supply powers up OK,a set of closed contacts in the main power supply keep the RED LED off and the 200V on. Rebuild of yours.
