Switch of input voltage range.
iii. PLC controller interface
Be used to connect programming controller, where
：
INTERLOCK
：
input the connecting locked signal
，
if off, starting output is not allowed.
TEST
：
Output synchronized-signal control when high voltage output is started.
START
：
Input the starting signal for outputting high voltage
，
corresponding to START
signal on the front panel.
