I have a 1994 mazak qt18 with a tplus control. I went to start it today and nothing happens. i hear the fans turn on when you turn the main switch on. However, when the Green start button is pressed, nothing happens. (the green button is illuminated) I had someone push the green start button while i was in the back electrical cabinet and i hear something clicking in the MITSUBISHI NC Power Supply QX084 and a red led flashes ( red circle in picture) . I have replaced the 2 - 24v power supplies shown in a blue circle and just checked and they appear ok. Does anyone know if i should focus on the NC power supply? anything to check w/ the meter?
on a normal startup i hear the main breaker trip, then the hydrualic pump.
