Troubleshooting

S611 Soft Starter
MN03901003E—January 2012 www.eaton.com
S611 Fault Codes, continued
Note:
All mains and control power connections must be completed and voltage applied prior
to a START command. Failure to make all connections will result in one or more faults.
All isolation and/or reversing contactors must be staged prior to any START commands.
Manipulating contactors after the START command will result in one or more faults.
Code
Fault
Condition
Solution
29
Current Unbalance
•
The current imbalance of the incoming
phases exceeds the trip threshold
•
Correct imbalance problem with mains
•
Increase the
Current Imbalance
parameters
•
Disable the fault if the other issues cannot be
resolved
30
Current Phase Loss
•
Incoming phase disconnected
•
Open fuse or breaker
•
Phase imbalance exceeds specifications
or trip parameter
•
Severe voltage phase imbalance
•
Repair broken connection
•
Replace fuse
•
Inspect system for phase imbalance conditions
31
Voltage Phase Imbalance
•
The voltage imbalance of the incoming
phases exceeds the trip threshold
•
Correct imbalance problem with mains
•
Increase the
Voltage Fault Imbalance
parameters
•
Disable the fault if the other issues cannot be resolved
33
Jam
•
Soft starter in bypass: Motor below rated
RPM and/or current exceeds 3 x motor
FLA
•
Remove obstruction
•
Verify proper FLA setting in Operation mode
•
Jam fault can be disabled if trips occur during normal
operation (Overcurrent fault will provide protection at
a higher current threshold of 4 x catalog FLA)
34
Contactor Overcurrent
•
Only active in bypass if the jam fault is
disabled
•
Current exceeds the fault threshold of
4 x catalog FLA
•
Remove obstruction in motor drive train
•
Verify S611 is properly sized for the application
35
Missing Temp Sensor
•
Temperature sensor failure
•
Internal connection failure
•
Internal hardware failure (sensor and/or cable)
•
Note:
Disabling this feature (
Temp Sense
fault in
Protection
menu) will remove protection from
excessive temperature exposure (not recommended)
•
Not field repairable, contact Eaton Support
*
Cannot RESET fault
•
Fault condition still exists
•
Soft starter has not received RESET
signal
•
Troubleshoot fault and correct defective condition
•
Attempt alternate methods of RESET
NC
No communication
•
Firmware not programmed, firmware
corrupted
•
