Flashing
Normal condition when control power is applied and bus voltage is less than
60V dc.
N/A
Steady Green
Normal condition when control power is applied and bus voltage is greater
than 60V dc.
N/A
Off Control power is not present Internal power supply failure Replace shunt module.
Temp Fault LED Status Potential Cause Possible Resolution
Off Normal condition N/A
Steady Red
SM internal temperature
exceeds operating
temperature specification
Shunt module fan failed Replace shunt module.
Shunt module temperature exceeds rating
• Allow shunt module to cool.
• Reset faults.
• Verify IAM bus regulator configuration.
External over temperature
condition
External temperature switch is open
• Allow shunt module to cool.
• Reset faults.
• Verify IAM bus regulator configuration.
TS jumper is not present Install jumper.
Shunt Fault LED Status Potential Cause Possible Resolution
Off Normal condition N/A
Steady Red
Shorted internal or external
shunt resistor
Mis-wired shunt jumper or other short on RC
connector
• Correct mis-wire (shorted) condition.
• If problem persists, replace shunt module.
Mis-wired (shorted) external shunt wiring
SM Status LED Status Potential Cause Possible Resolution
• Bus Status
• Temperature Fault
• Shunt Fault
All three SM status LED
indicators flash
simultaneously
Shunt module hardware failure
• Cycle power.
• If problem persists, replace shunt module.
