Rectifier Current Limit
Rectifier(s) in current limit.
Rectifier Fail
A rectifier is faulty or its ac supply has failed without causing partial or total ac
supply failure.
Rectifier No Load
The total rectifier current is less than 2% of the maximum system output current or is
less than 2A.
Rectifier Over
Temperature
Rectifier(s) operating in temperature turndown mode, because of high ambient
temperature or low ac supply voltage.
Sensor Fail
The current, temperature or voltage sensing system is faulty, or the I/O board
mapping is incorrect.
Standby Mode
The SC100 is on but inactive. Another system controller controls the dc power
system. If the other system controller fails or is disconnected then the SC100 in
Standby Mode will become active (after a short delay).
System Overload
The power system is operating close to its maximum capacity and more rectifiers are
needed. The System Overload threshold is configurable. See System Overload Alarm
on page
Temperature Sensor Fail
The temperature sensing system is faulty, or the I/O board mapping is incorrect.
Unknown Hardware
The SC100 has detected an unknown type of device on the RXP bus. Contact your
Eaton DC product supplier for advice.
