Table 6.11 IFIELD-MODULE Indicators on the ICE-FML Board
Indicators Description
+15 ISO OK LED indicator for isolated +15V power supply, measured with respect to isolated
Ground, GND-ISO. Normally ON. Turns OFF when module loses +15 ISO voltage.
F. BAD LED indicator for AC input on FMX1 and FMX2 terminals (on FMP board). Normally
ON. Turns OFF when any input side AC fuse opens.
+15 OK LED indicator for +15V power supply, measured with respect to Ground. Normally
ON. Turns OFF when module looses +15V.
HI TEMP LED turns ON to indicate high temperature on the heat sink. Normally OFF. Turns
ON when the temperature of the main IGBT raises above 85
o
C (185
