Table 6.6 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
OFF. Turns ON 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 heatsink. Normally OFF. Turns ON
when the temperature of the main IGBT raises above 85
o
C (185
o
F).
IGBT FLT LED turns ON to indicate that the AUX IGBT has failed open.
Table 6.7 IFIELD MODULE Terminals on the ICE-FML Board
Terminal Description
1 1 BUS: AC input supply to the ICE-FML Board.
2 2B BUS: AC input supply to the ICE-FML Board.
FAN 1 (not used) Terminals for connecting an external fan.
FAN 2 (not used) Terminals for connecting an external fan.
TEMP 1 (not used) Terminals for connecting an external temperature sensor.
TEMP 2 (not used) Terminals for connecting an external temperature sensor.
Table 6.8 IFIELD-MODULE Terminals on the ICE-FMP Board (Brake Module)
Terminal Description
FMO+ Field Module Output, positive, to brake coil.
FMO- Field Module Output, negative, to brake coil.
FMSI Field Module Safety Input: Jumpered to FMSO. FMSI and FMSO are always jumpered
together unless there is a requirement for a mechanical safety contact to break
between the load and the field module.
FMCI Field Module Current Input: When load current is higher than 10A, jumper FMCI to
FMHC. For load current less than 10A, leave both FMCI and FMHC open.
FMHC Field Module High Current: See FMCI.
FMS1 Field Module Snubber 1: When used as a Brake Module, a shunt RC parallel network
(RB & CB) is connected between FMS1 and FMLD.
FMS2 Field Module Snubber 2: N/C
FMLD Field Module Load Diode: FMLD is connected to the cathode of a diode on the ICE-
FMP board. FMLD is also connected to RC network RB & CB (see FMS1).
FMSO Field Module Safety Output: Jumpered to FMSI. (see FMSI)
FMX1 AC power input to Field Module from brake contacts (70 VAC min, 300 VAC max)
FMX2 AC power input to Field Module from brake contacts (70 VAC min, 300 VAC max)
