internal power supply. At the same time, the signal of fault will output a conduction
signal with the 9th pin (EX_AL) and the 10th pin (EX_ALARM_OUT-)
in the 16 pin Ctrl_Interface on the rear panel. And then the front panel display will
display the fault information at this time.
The customers can make detailed query on the software fault query page when
