Output Signal to FEC
The following signals are sent to FEC via BACKPLANE board.
•
OV(Over Voltage), OC(Over Current) of each power source : HV tests in itself. The result transmits
the FEC via BACKPLANE ASSY.
5-4-7-4
Input Signal from FEC
The following signals are sent to HV unit via FEC > BACKPLANE board.
•
+5V, +/- 15V, HV STOP: These signals are sent to PFC to control DC voltage output of HVH, HVL,
and -SHV. Normally HVSTOP is ON
-
HVH Ref, HVL Ref: These are the digital signals (8 bits) sent to the DAC of HVH or HVL from
FEC. Consequently, The DC Voltage (0 - 60V) is outputted from HV unit.
