Indicators Description
+15v ISO 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 ICE-FM board). Normally
OFF. Turns ON when any input side AC fuse opens.
+15v 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 board raises above 85
o
C (185
