4� Features
4�1 Converter Modules
A module contains four isolated DC to DC converters with a common control and supervisory circuit. Each module
output operates independently. An internal micro controller monitors both the inputs and outputs of the converters,
turns the converters on and off, and generates a converter fail alarm if required.
4�1�1 Status Indicators
The converter module has four LED indicators – one per converter. The LEDs are color-coded to indicate converter
status as follows:
Table A — Converter Status LEDs
LED State Converter Status
Green Normal
Blinking Green Remote shutdown enabled on individual
channel/converter
Blinking Green
(All 4 LEDs)
Shelf is not compatible with the module
Module not seated properly
Yellow (All 4 LEDs)
Recoverable:
• Ambient temperature high
Blinking Yellow (All 4
LEDs)
Input qualify not OK
Blinking Yellow Recoverable:
• OCP/Overload
Non-recoverable:
• Converter Input Fuse fail
Red Locked-State:
• OVP
Non-recoverable:
• Converter Output Fuse fail
Blinking Red
Recoverable:
• GFI
OFF (All 4 LEDs) Recoverable:
• No power
Non-recoverable:
• Main Input Fuse cut-off
Chasing Red/Green

4�1�2 Converter Alarms
Two converter fail outputs are present at the card edge connector. Alarms are activated after a one second delay for
the following conditions:
•
Internal regulation fails
• Output voltage <±140V
• Over Voltage Protection (OVP) operation
• Ground Fault Interrupt (GFI) trip
• Input fuse or output fuse fail
• Output short circuit (±30V ± 20%)
• Input voltage out of range
• Heatsink/ ambient temperature out of range (Over Temperature Protection - OTP)
